Particles are suspended by an electric field so as to grow large enough to be observed by an optical microscope. It is found that the particles are single crystals and have particular shapes depending on the gas temperature and the laser-light intensity. 1392 0031-9007 13 Physical Review Letters 1390 http://link.aps.org/doi/10.1103/PhysRevLett.63.1390 63 The American Physical Society Shapes of laser-produced CsH particles 2433/75426 Suito, Eiji 1954/03/31 87 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 85 32 Institute for Chemical Research, Kyoto University On the Characteristic Properties of the Three-Stage Electron Microscope SM-C3 as an Electron Diffraction Camera 2433/52361 OKADA, Yoshio 1969/12/25 The terminal bronchiolar epithelium of the mouse and the guinea pig were examined with the scanning electron microscope and the conventional electron microscope. The ciliated cells and the Clara cells were well preserved and it is possible to discern individual cell with the scanning electron microscope. The apical part of the cytoplasm containing the agranular endoplasmic reticulum was occasionally seen to be extruded into the bronchiolar lumen. This finding indicated that the Clara cell has an apocrine secretory function. Osmiophilic lamellar inclusions are rarely found in this cell. However, there is no proof that they are the important source of the pulmonary surfactant. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 10 0009-3378 1 京都大学結核胸部疾患研究所紀要 1 3 京都大学結核胸部疾患研究所 THE ULTRASTRUCTURE OF THE CLARA CELL IN THE BRONCHIOLAR EPITHELIUM 2433/77483 Kobayashi, Takashi 1993/02/26 461 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 451 70 Institute for Chemical Research, Kyoto University High Resolution Electron Spectro-Microscope (HRESM) 2433/75365 Suito, Eiji 1953/09/30 360 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 359 31 Institute for Chemical Research, Kyoto University Crystal Structure Analysis of the "Trigon" Particles of Colloidal Gold by a Three-Stage Electron Microscope 2433/75273 Suito, Eiji 1953/01/30 49 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 47 31 Institute for Chemical Research, Kyoto University Studies of Organic Pigments by Electron Microscope 2433/74236 Suito, Eiji 1951/03/30 74 0023-6071 京都大学化学研究所報告 74 24 京都大学化学研究所 Studies on the Ultrafine Powders for Industrial Use by Means of Electron Microscope and Electron Diffraction 2433/72819 IWATA, Fumio 2008/04/30 The present paper deals with three species of monostiliferous hoplonemerteans collected in the San Juan Archipelago, Washington state, USA in 1964. Two were originally described as Amphiporus formidabilis Griffin, 1898 and A. imparispinosus Griffin, 1898; the third was originally described as Amphiporus punctatulus Coe, 1905, later became the type species of the genus Nipponnemertes (Crandall, 2001). Specimens were fixed in Bouin's solution after anesthetized by addition of menthol or 70 % alcohol. Two specimens of both Amphiporus species and two specimens of N. punctatula were sectioned at 8 μm and stained with Delafield's hematoxylin and eosin. A Sony video camera with Symphonic monitor television and Sony color video printer, in addition to an Olympus BH-2 microscope, were used for observation of the material. 45 0037-2870 5-6 Publications of the Seto Marine Biological Laboratory 9 40 Seto Marine Biological Laboratory, Kyoto University Nemertea On Three Monostiliferous Hoplonemerteans from the San Juan Archipelago, Washington State, USA 2433/3673 Gotoh, Y 2002/10/30 11 0921-5093 1-2 MATERIALS SCIENCE AND ENGINEERING A-STRUCTURAL MATERIALS PROPERTIES MICROSTRUCTURE AND PROCESSING 6 353 ELSEVIER SCIENCE SA electronic perturbation On the stability of electronic perturbations on a graphite surface produced by low-energy ion bombardment 2433/8386 Yamamoto, S 1999/10/30 3720 0021-4922 6B JAPANESE JOURNAL OF APPLIED PHYSICS PART 1-REGULAR PAPERS SHORT NOTES & REVIEW PAPERS 3717 39 JAPAN J APPLIED PHYSICS Au islands Differentiation of Au islands on Ni film by friction force microscopy, force curve and new force modulation method 2433/7141 Saya, Y 1999/10/30 3803 0021-4922 6B JAPANESE JOURNAL OF APPLIED PHYSICS PART 1-REGULAR PAPERS SHORT NOTES & REVIEW PAPERS 3799 39 JAPAN J APPLIED PHYSICS ferroelectric thin films Investigation of nonswitching regions in ferroelectric thin films using scanning force microscopy 2433/34885 Kitagawa, F 2005/10/30 42 0021-9673 1-2 JOURNAL OF CHROMATOGRAPHY A 36 1106 ELSEVIER SCIENCE BV capillary electrophoresis Toward million-fold sensitivity enhancement by sweeping in capillary electrophoresis combined with thermal lens microscopic detection using an interface chip 2433/75362 Ishibashi, Masayoshi 1953/09/30 367 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 365 31 Institute for Chemical Research, Kyoto University Morphology of Organometallic Precipitates by Electron Microscope 2433/74411 Ueda, Shizuo 1952/03/30 57 0023-6071 京都大学化学研究所報告 57 28 京都大学化学研究所 Study on Surface Electricity.

Two kinds of surface cells were identified. Long filamentous cilia covered the free surface of the ciliated cells and frequently extended over the hollows formed by non-ciliated cell surfaces. Many well-preserved erythrocytes were seen on the somewhat rough surface of the pulmonary vein. The three dimensional features of collagen fibers in subbronchial connective tissue were also demonstrated. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 170 0009-3378 2 京都大学結核胸部疾患研究所紀要 163 2 京都大学結核胸部疾患研究所 SCANNING ELECTRON MICROSCOPY OF THE BRONCHUS AND ADNEXES OF RATS 2433/93321 木村, 吉秀 1988/09/20 この論文は国立情報学研究所の電子図書館事業により電子化されました。 1092 0527-2997 6 物性研究 1092 50 物性研究刊行会 27.

Fresh green samples of two conifer species, SUGI (Cryptomeria japonica D. DON) and KUROMATSU (finus thunbergii PARL.) were used, and each sample of species was classified into 3 groups and treated respectively by the different methods, that is, two drying methods (drying at 105℃ and air drying at room temperature) and FAA treatment known as a fixing one, and again treated respectively with sodium hydroxide solution of four different concentrations (1, 0.5, 0.25 and 0.125%). And then, from all these samples treated, small block specimens were prepared according to the electron microscope technique, and sections of about 2 p thickness were cut and observed under a phase contrast microscope. From the results of this experiment, it was indicated that there was a possibility of dissolving or removing tori without large modification of the morphological features of cell walls or pit borders, and it was known that even a dilute solution of sodium hydroxide such as 0.125% was also well available to dissolve the pectic material of tori, that the difference of concentration would be almost negligible within the limits of this experiment, and that no remarkable difference existed between the two drying treatments but only some general tendencies were recognized in the case of concentration differences and drying methods. As to SUGI wood, the comparatively remarkable effect of FAA was recognized, but similar result of FAA on KUROMATSU wood was not obtained. Then, the causes of balloon-like expansion of half-bordered pit membranes, and of curving pit borders in the direction to tracheid lumina were also discussed and presumed. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 105 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 90 52 Wood Research Institute, Kyoto University Artificial Modification of Bordered Pits in Softwoods : (1) Treatment with Sodium Hydroxide Solution 2433/74095 Sawai, Ikutaro 1950/06/30 64 0023-6071 京都大学化学研究所報告 63 21 京都大学化学研究所 Studies on the Manufacture of Roofing Tiles "Kusube Gawara".

The light intensities passed through sample specimens, i, e. votage values, were digitized and converted to absorbances by this microscope-microcomputer system. This computer program was written in BASIC and consists of three subroutines, i.e. analogue/digital conversion, reading data into a diskette, and processing parts. The absorbances thus obtained were then summarized as frequency histograms with sample numbers, mean values, variances and standard deviations for every morphological cell types on CRT (Cathode Ray Tube). Possible applications and limitations of this system were described. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 41 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 32 70 Wood Research Institute, Kyoto University A Microcomputer System with an Analogue/Digital Converter for Cytophotometry 2433/84971 2008/10/30 47 1342-0321 ICR annual report 46 15 Institute for Chemical Research, Kyoto University Electron Microscopy and Crystal Chemistry 2433/75610 Suito, Eiji 1958/03/30 152 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 150 35 Institute for Chemical Research, Kyoto University A Specimen Preparation Technique for the Crystal Habit 2433/95080 Teramura, Yuji 2010/02/27 Cell-cell interactions play vital roles in embryo development and in homeostasis maintenance. Such interactions must be stringently controlled for cell-based tissue engineering and regenerative medicine therapies, and methods for studying and controlling cell-cell interactions are being developed using both biomedical and engineering approaches. In this study, we prepared amphiphilic PEG-lipid polymers that were attached to polyDNA with specific sequences. Incubation of cells with the polyDNA-PEG-lipid conjugate transferred some of the polyDNA to the cells' surfaces. Similarly, polyDNA-PEG-lipid conjugate using polyDNA with a complementary sequence was introduced to the surfaces of other cells or to a substrate surface. Cell-cell or cell-substrate attachments were subsequently mediated via hybridization between the two complementary polyDNAs and monitored using fluorescence microscopy. 2235 1878-5905 8 Biomaterials 2229 31 Elsevier Cell-cell attachment Control of cell attachment through polyDNA hybridization. 2433/76377 Shiojiri, Makoto 1971/11/05 229 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 222 49 Institute for Chemical Research, Kyoto University Electro-Crystallization of Silver in Silver Iodide Films 2433/160653 Moon, Chiwon 2011/01/01 Defects inside single crystals are an important concern because they directly affect the physical or chemical properties of the material, especially in sapphire used as substrates for semiconductors. We have investigated the thermally activated transformations of nanometer-scale cracks and phase transitions inside sapphire by femtosecond laser irradiation and successive heat treatments. The nanocracks transformed into periodic arrays of pores and dislocations that aligned along the {1Ī02} planes after heat treatments above 1300 °C. The amorphous phase at the focal point recovered into the initial single crystalline phase after the heat treatments. Our study provides useful information on the recovery behavior of nanometer-scale defects in a single crystal. 0021-8979 1 JOURNAL OF APPLIED PHYSICS http://link.aip.org/link/?jap/109/013517 109 American Institute of Physics cracks Morphology change from nanocrack into periodic pore array formed by femtosecond laser pulses 2433/75487 Suito, Eiji 1954/10/30 28 0023-6071 s Bulletin of the Institute for Chemical Research, Kyoto University 18 32 Institute for Chemical Research, Kyoto University Paper IV Colloid Morphological and Crystalline Studies of "Bikini Dust" fallen on the No. 5 Fukuryu Maru by Electron Microscopy and Diffraction Methods.

Counterclockwise rotation of the filaments allows them to join in a bundle and propel the cell forward. Loss of motility can be caused by environmental factors such as temperature, pH, and solvation. Hydrostatic pressure is also a physical inhibitor of bacterial motility, but the detailed mechanism of this inhibition is still unknown. Here, we developed a high-pressure microscope that enables us to acquire high-resolution microscopic images, regardless of applied pressures. We also characterized the pressure dependence of the motility of swimming Escherichia coli cells and the rotation of single flagellar motors. The fraction and speed of swimming cells decreased with increased pressure. At 80 MPa, all cells stopped swimming and simply diffused in solution. After the release of pressure, most cells immediately recovered their initial motility. Direct observation of the motility of single flagellar motors revealed that at 80 MPa, the motors generate torque that should be sufficient to join rotating filaments in a bundle. The discrepancy in the behavior of free swimming cells and individual motors could be due to the applied pressure inhibiting the formation of rotating filament bundles that can propel the cell body in an aqueous environment. 1880 0006-3495 8 Biophysical Journal 1872 102 Elsevier Inc.

Both calculated YOUNG'S moduli of cell wall substances and of crystalline rich cell wall also increased. Because the increasing pattern of α-cellulose, lignin and crystalline region were not similar to that of the moduli, a distinct linear correlation between these structural parameters and the modulus could not be found. Contributions of these constituents to mechanical characteristics of the growing hypocotyls are discussed. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 12 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 7 56 Wood Research Institute, Kyoto University On the YOUNG'S Modulus during Growth of Pine Seedlings 2433/53337 TANAHASHI, Mitsuhiko 1983/03/25 Wood chips of Shirakaba (Betula platiphilla Skatchev var, Japonica Hara) and Karamatsu (Larix leptolepis Gordon) were treated with a high pressure steam (12-28 kg/cm^2) for 1-16 min., and the steam pressure was released instantaneously to result in explosion wood. When the treating time was longer more fibrillation of cell walls of Shirakaba occurred. However, Karamatsu chips gave small non-fibrillated block fragments. Fibers of the explosion wood of both woods were observed to be vigorously ruptured. Glycosidic linkage of hemicelluloses and alkyl-aryl linkages of lignin were hydrolyzed to give low molecular weight fragments. Cellulose, on the other hand, remained apparently intact. The crystallinity and micelle width were found to be increased by explosion. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 51 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 36 69 Wood Research Institute, Kyoto University Characterization of Explosion Wood : 1.

This method is dependent upon the principle of specific formation of acid chloride from the carboxyl group through the action of thionyl chloride in the first step of the method. Newly formed acid chloride was converted into acid amide in a dilute ammonia solution in the second step. The acid amide was precipitated as a metaphosphate in a concentrated sod. metaphosphate solution in the third step. Thereafter, metaphosphate was converted into silver salt in a silver nitrate solution. The silver salt was reduced to metallic silver by the neutral formol solution. The metallic silver was replaced by metallic gold by immersing in a gold chloride solution to inprove observation under a microscope. There were some problems encountered in this method which are described in the item of comment of this report. Further investigations will be performed by the authors. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 74 2 Acta tuberculosea Japonica 69 6 Tuberculosis Research Institute, Kyoto University Histochemical Specific Demonstration of the Carboxyl Group in Tissue Sections 2433/52979 KATO, Hiroyuki 1965/11/29 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 60 0049-7916 木材研究 : 京都大學木材研究所報告 55 36 京都大學木材研究所 チロースの形態について Some Morphological Observations of Tyloses 2433/120909 Nakaya, Takayuki 2010/03/23 Kyoto University femtosecond laser フェムト秒レーザによる誘電体材料内部への微小構造形成に関する研究 Studies on fabrication of microstructures in dielectric materials by femtosecond laser pulses 2433/76042 Kobayashi, Keinosuke 1965/07/15 493 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 473 42 Institute for Chemical Research, Kyoto University The Changes of Polymer Crystals due to Irradiation with Electrons Accelerated at Various Voltages (Special Issue on Electron Microscopy) 2433/152427 Liu, Yi-Hung 2012/01/30 In this study, we have investigated the application of dry ice blasting to remove fine particles adhering to surfaces and examined the removal process. The removal efficiency, area, and frequency have been analyzed using images captured with a high-speed microscope camera. In addition, the temperature of the dry ice jet has been measured in order to evaluate the dry ice particles and their effects on the particle removal process. The removal processes due to the impacts of primary dry ice particles and their agglomerates occurred in two stages corresponding to slow and rapid particle removals. High removal efficiency was achieved when the impacts of the agglomerates were dominant during the particle removal at approximately − 70 °C. Furthermore, we have investigated the effects of the jet flow rate on the removal area and frequency and proposed a system parameter to determine the optimum jet flow rate for efficient particle removal. 613 0032-5910 Powder Technology 607 217 Elsevier B.V.

Its ciliary movement plays a role of cleaning the respiratory passage. For the ciliary movement, ciliated epithelial cells have probably large energy requirements and glucose from the blood is an important source of the energy. Therefore, it is of interest whether, or how, glucose 6-phosphatase (G-6-Pase), an important enzyme in glucose metabolism, is localized in the cells. Female Sprague-Dawley rats, about 100g, were used. They had free access to food and water prior to experiments. About 0.5mm thick cross-sectioned tracheae adjacent to the bifurcation of the trachea were fixed in 2% glutaraldehyde buffered with 0.1M cacodylate (pH7) for 30 minutes at 4℃ and washed in 0.1M cacodylate (pH 7) for 1 hour at 4℃. The tissues were cut into 30μ sections by a freezing microtome and incubated in Wachstein and Meisel's medium for the demonstration of G-6-Pase for 45 minutes at room temperature. The sections were postfixed in buffered 1% osmium tetroxide for 1 hour at 4℃, dehydrated in graded series of alcohol and embedded in Epon. Thin sections were cut with glass knives on a LKB ultratome, stained with uranyl acetate and lead citrate and examined in a JEM-7 A electron microscope. Control experiments were carried out as described previously. The reaction product was present in the endoplasmic reticulum and nuclear envelope of ciliated cells, together with goblet cells. Golgi complex, mitochondria, plasma membrane and other organellae of these cells showed no deposits of final product. This pattern of localization is entirely equal to that of the enzyme in hepatocytes and other cells, although new findings were expected because ciliated cells probably consume a large amount of glucose as a energy source of the ciliary movement. G-6-Pase has an important role in carbohydrate metabolism, In the liver and kidney, gluconeogenesis and glycogenolysis are important pathways, and the role of G-6-Pase is to release glucose into the blood from these organs. However, the physiologic function this enzyme is unknown in a variety of other organs. Arion et al. have recently suggested that the physiologically functional form of this enzyme is specific for glucose 6-phosphate and hydrolysis of glucose 6-phosphate is the sole function of the enzyme in vivo. On the other hand, tracheal ciliated cells and goblet cells probably have large glucose 6-phosphate requirement as the energy source for the ciliary movement and material for biosynthesis of secretory glycoprotein. Thus, these cells possibly have a potent ability to produce glucose 6-phosphate from glucose in the blood. One might, therefore, postulate that the role of G-6-Pase is to regulate the level of concentration of glucose 6-phosphate in these cells, hydrolyzing excess glucose 6-phosphate produced by these cells. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 10 0009-3378 1 京都大学結核胸部疾患研究所紀要 8 8 京都大学結核胸部疾患研究所 CYTOCHEMICAL LOCALIZATION OF GLUCOSE 6-PHOSPHATASE IN CILIATED CELLS OF RAT TRACHEAL EPITHELIUM 2433/84975 2008/10/30 39 1342-0321 ICR annual report 38 15 Institute for Chemical Research, Kyoto University Molecular Aggregation Analysis 2433/84977 2008/10/30 35 1342-0321 ICR annual report 34 15 Institute for Chemical Research, Kyoto University Polymer Materials Science 2433/46951 Linsley, F.

Instruments for recording spermatozoal movement consisted of a phase-contrast microscope, a camera head, a camera control unit, an X-Y tracker, a TV monitor and an X-Y recorder. These are assembled as illustrated in Fig's. 1 and 2. The X-Y tracker, one of the most important instruments in this system, was devised for use in aeronautics or architecture, such as to monitor the orbit of a rocket, to measure the sway of skyscrapers to predict when it might crumble down during an earthquake and to measure the sway of a big bridge to determine whether it would hold during a storm. In the spermatozoal trackogram the spermatozoon progressed in a roughly straight line in a sine curve, and at times in a rectangular wave (Fig. 2 to 5). The speed of spermatozoa movement in the X and Y directions can be immediately and automatically calculated if a computer is connected to this system. The system will be useful for recording the movement of a single free cell. 158 0018-1994 2 泌尿器科紀要 153 28 泌尿器科紀要刊行会 SPERMOTOZOAL TRACOGRAPHY - TRACING OF THE MOVEMENT OF A SPERMATOZOON - A PRELIMINARY REPORT ヒト精子細胞の運動軌跡 -精子運動軌跡図- の描記法(予報) 2433/156133 Fujimoto, R. 2012/06/29 The propagation of surface plasmon polaritons (SPPs) on Ag waveguides with two different widths is directly observed using dual-probe scanning near-field optical microscopy (DSNOM). We find that the waveguide structure strongly affects the propagation of locally excited SPPs. SPPs in a flat plane structure spread radially, whereas SPPs in a 3.4-μm wide waveguide structure form two-dimensional interference fringes due to the multiple reflections at the side edges. The experimental results agree well with finite-difference time-domain calculations. The results suggest that the DSNOM technique can visualize the nanoscale characteristics of the SPP waves in various plasmonic waveguides. 7376 0169-4332 19 Applied Surface Science 7372 258 Elsevier B.V.

It has been proposed that the heat-modification occurs in the region in which the temperature had overcome a threshold temperature during exposure of laser pulses. In order to understand the mechanism of the heat-modification, we investigated the temperature distribution during laser exposure and the threshold temperature by analyzing the volume of the modification based on a thermal diffusion model. We found that the threshold temperature becomes lower with increasing laser exposure time. The dependence of the threshold temperature on the laser exposure time was explained by the deformation mechanism based on the temperature-dependent viscosity and viscoelastic behavior of a glass under a stress loading by thermal expansion. The deformation mechanism also could simulate a tear-drop shape of a heat-modification by simultaneous double-beams’ irradiation and the distribution of birefringence in a heat-modification. The mechanism proposed in this study means that the temperature-dependence of the viscosity of a glass should be essential for predicting and controlling the heat-modification. 0021-8979 7 Journal of Applied Physics 108 American Institute of Physics birefringence Mechanism of heat-modification inside a glass after irradiation with high-repetition rate femtosecond laser pulses 2433/145964 Hashida, Masaki 2011/05/30 Crystal structures on a single-crystalline copper film with a periodic self-organized surface induced by femtosecond laser pulses with fluences of 0.08–0.64 J/cm[2] have been analyzed by transmission electron microscopy. It was found that the crystal structures depend on laser fluence: polycrystalline structures are formed at fluences less than 0.2 J/cm[2], an amorphous state forms around 0.3 J/cm[2], and polycrystalline structures form again at fluences greater than 0.35 J/cm[2]. The energy spectrum of ions emitted during the formation of periodic structures on the surface shows that the energy of copper ions is high enough to transform the crystal to an amorphous state. A conceptual mechanism for crystal structure transformation by the penetration of energetic ions generated in the process of self-organization of periodic structures is proposed. 1098-0121 23 Physical Review B 83 American Physical Society Crystal structures on a copper thin film with a surface of periodic self-organized nanostructures induced by femtosecond laser pulses 2433/76703 1977/03/25 389 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 381 54 Institute for Chemical Research, Kyoto University Laboratory of Powder and Crystal Chemistry (Special Issue on the Commemoration of the Fiftieth Anniversary) 2433/77138 Uemura, Akio 1986/07/25 77 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 66 64 Institute for Chemical Research, Kyoto University Morphology of Solution-grown Crystals and Crystalline Thin FiIms of Poly (p-phenylene sulfide) 2433/46103 平田, 文夫 1937/08/30 274 4 物理化學の進歩 262 11 日本物理化學研究會 熱可逆凝膠の剛性と構造に就て On the rigidity and the constitution of a thermoreversible gel 2433/77466 Sakata, Kazumi 1992/10/30 269 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 257 70 Institute for Chemical Research, Kyoto University Methods for Orienting Purple Membrane in Vitreous Ice (Commemoration Issue Dedicated to Professor Shigeo Tanimoto On the Occation of His Retirement) 2433/108619 Hiroi, Junya 1998/07/30 To investigate the involvement of the yolk-sac membrane in ion absorption, developmental changes in whole-body cation contents, cellular localization of vacuolar-type H^[+]-ATPase (V-ATPase), and size and density of pavement and chloride cells in the yolk-sac membrane were examined in tilapia (Oreochromis mossambicus) larvae in fresh water (FW) and those transferred to seawater (SW) at 2 days before hatching (day-2). The whole-body content of Na^[+] in embryos and larvae adapted to both FW and SW increased constantly from day-2 to day 10, although they were not fed through the experiment. The yolk-sac membrane of FW larvae at days 0 and 2 showed V-ATPase immunoreactivity in pavement cells, but not in chloride cells. No positive immunoreactivity was detected in SW larvae. Whole-mount immunocytochemistry showed that some pavement cells were intensively immunoreactive, whereas others were less or not immunoreactive. Electron-microscopic immunocytochemistry revealed that V-ATPase immunoreactivity was present in the apical regions of pavement cells in FW larvae, especially in their ridges. The pavement cells in FW larvae were significantly smaller in size but higher in density than those in SW. These results suggest that pavement cells are the site of active Na+ uptake in exchange for H+ secretion through V-ATPase in FW-adapted tilapia during early life stages. 453 0289-0003 4 Zoological Science 447 15 Zoological Society of Japan Immunolocalization of Vacuolar-Type H+-ATPase in the Yolk-Sac Membrane of Tilapia (Oreochromis mossambicus) Larvae 2433/160051 Blanchard, F. 2012/08/09 A terahertz microscope has been used to excite and observe the resonant modes of a single split ring resonator in the reactive and radiative near-field zones. The two lowest resonant modes of an isolated split ring resonator with their corresponding radiation patterns are reported; they showed good agreement to simulations. The passage from the reactive to radiative near-field zone is also discussed. Further, our result introduced a novel technique to perform terahertz time-domain spectroscopy of samples a few tens of micrometers in size by measuring the in-plane radiative near-field zone. 19403 1094-4087 17 Optics Express 19395 20 Optical Society of America Terahertz spectroscopy of the reactive and radiative near-field zones of split ring resonator 2433/93442 Ogawa, Hiroki 2008/05/13 We report structural development in blend thin films of deuterated polystyrene (dPS) and poly(vinyl methyl ether) (PVME) below not, vert, similar200 nm in two phase region during the incubation period before dewetting using neutron reflectivity (NR) and atomic force microscopy (AFM). As was predicted by the former optical microscope (OM) and small-angle light scattering (LS) measurements on blend thin films of protonated PS and PVME [Ogawa H, Kanaya T, Nishida K, Matsuba G. Polymer 2008;40:254–62.], the NR results clearly showed that the tri-layer structure consisting of the surface PVME layer, the middle blend layer and the bottom PVME layer was formed in the one phase region. After the temperature jump into the two phase region, it was found that the phase separation of the middle blend layer proceeded in the depth direction during the incubation period before dewetting, suggesting that the dewetting was induced by the composition fluctuations during the incubation period. 2559 0032-3861 10 Polymer 2553 49 Elsevier Polymer blend thin film Composition fluctuations before dewetting in polystyrene/poly(vinyl methyl ether) blend thin films 2433/50509 Sakakura, Masaaki 2002/12/30 894 0034-6748 1 REVIEW OF SCIENTIFIC INSTRUMENTS 892 http://link.aip.org/link/?rsi/74/892 74 AMER INST PHYSICS Study on the femtosecond laser-induced refractive index change in a silicate glass by transient lens method 2433/75494 Suito, Eiji 1955/01/31 13 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 8 33 Institute for Chemical Research, Kyoto University Surface Area Measurement of Powders by Adsorption in Liquid Phase.

Pearly-white tumors began to appear in a few weeks after the last injection. Light microscopic observations revealed that the benign adenomas arose from the alveolar region remote from any possible contact with the bronchioli. In the early stages, proliferation of the alveolar wall cells were shown by electron microscopic observations. The tumor cells are divided into three types according to their fine structures; (1) cells bearing osmiophilic bodies in their cytoplasm, which resemble the alveolar wall cells, (2) ciliated cells devoid of osmiophilic bodies, which resemble the ciliated cells of the bronchial epithelium, (3) non-ciliated cells devoid of osmiophilic bodies, which resemble in shape the cuboidal cells of the terminal bronchioli. Therefore, it is indicated that these induced pulmonary tumors in mice probably originate from the alveolar wall cells. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 82 2 Acta tuberculosea Japonica 73 11 Tuberculosis Research Institute, Kyoto University MORPHOLOGICAL STUDIES OF INDUCED PULMONARY TUMORS IN MICE WITH SPECIAL REFERENCE TO THEIR CYTOGENESIS 2433/39937 Hiramatsu, S 2004/08/30 2077 1041-1135 9 IEEE PHOTONICS TECHNOLOGY LETTERS 2075 16 IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Laser-written optical-path redirected waveguide device for optical back-plane interconnects 2433/39664 Qu, SL 2004/03/22 2048 0003-6951 12 APPLIED PHYSICS LETTERS 2046 http://link.aip.org/link/?apl/84/2046 84 AMER INST PHYSICS Metal nanoparticle precipitation in periodic arrays in Au2O-doped glass by two interfered femtosecond laser pulses 2433/49850 Kubo, K 2003/09/22 2470 0003-6951 12 APPLIED PHYSICS LETTERS 2468 http://link.aip.org/link/?apl/83/2468 83 AMER INST PHYSICS Optically driven transport into a living cell 2433/169121 Yamazaki, Shinichi 2009/04/20 In order to clarify the effects of entanglement species on nucleation of polymers, we studied the nucleation rate I of cyclic and linear polyethylenes (C-PE and L-PE) from the melt as a function of degree of supercooling ΔT by means of polarizing optical microscope. We prepared several C-PEs with different weight average molecular weights M_w=4600-114800. I of all the sample were obeyed the equation, I=I_0exp(-C/ΔT^2). I_0s of C-PE with M_w=114800 and L-PE with M_w=35400 were almost the same. This indicates that C-PE is easier to nucleate than L-PE due to lack of knot entanglements. On the other hand, Cs for C-PE significantly increased with increasing M_w. This tendency is quite different with L-PE previously reported. The increase of C indicates that folding regularity of end surface of nucleus increases. Since topological constraint of C-PE arose from the lack of chain ends is relatively decreased with increasing M_w, it was implied that the nucleation behavior of C-PE approaches that of L-PE. この論文は国立情報学研究所の電子図書館事業により電子化されました。 50 0727-2997 1 物性研究 47 92 物性研究刊行会 Topological Mechanism of Nucleation of Cyclic Polyethylene(Knots and soft-matter physics: Topology of polymers and related topics in physics, mathematics and biology) 2433/85394 宍戸, 信之 2009/09/24 京都大学 デジタル画像相関法 デジタル画像相関法を用いた微細領域ひずみ場計測とその工学的応用 2433/128847 Takinoue, Masahiro 2010/03/12 We report the rotary motion of an aqueous microdroplet in an oil phase under a stationary direct current electric field.

In this study, we determined the temperature distribution due to heat accumulation and the characteristic temperature for heat modification inside a soda lime glass by analyzing the relationship between the radius of modification and glass temperature. The validity of the analysis was confirmed by reproducing the modification due to two-beam irradiation. The determined characteristic temperature suggested that the temperature distribution and the spatial dependence of the stress relaxation are important in the mechanism of heat modification. 0003-6951 23 APPLIED PHYSICS LETTERS http://link.aip.org/link/?APPLAB/93/231112/1 93 American Institute of Physics calcium compounds Temperature distribution and modification mechanism inside glass with heat accumulation during 250 kHz irradiation of femtosecond laser pulses 2433/84591 Yang, Weijia 2008/10/27 Control of structural modifications inside silica glass by changing the front tilt of an ultrashort pulse is demonstrated, achieving a calligraphic style of laser writing.

The index profile in the photoinduced area has a ring-shaped pattern, which indicates that local densification occurred in the glass. An irregular surface reflecting the density distribution is formed around the focal point by dry etching process using a focused ion beam. By the irradiation of femtosecond laser pulses, the effect of ion exchange between the focal point and the surrounding area is also observed in the area in which local densification occurred. 0003-6951 2 APPLIED PHYSICS LETTERS http://link.aip.org/link/?APPLAB/93/023112/1 93 American Institute of Physics Ion exchange in glass using femtosecond laser irradiation 2433/75358 Sawai, Ikutaro 1953/09/30 375 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 374 31 Institute for Chemical Research, Kyoto University A Method of Sampling for Obtaining the Daily Average of Batch Composition 2433/75361 Suito, Eiji 1953/09/30 369 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 368 31 Institute for Chemical Research, Kyoto University Sedimentation Analysis of Powders.

The following species were found: Teredo navalis LINNAEUS and Limnoria lignorum (RATHKE) at Onagawa, T. navalis, Lyrodus pedicellatus (QUATREFAGES), Bankia carinata (GRAY) and L. lignorum at Tatok Island, T. navalis, L. pedicellatus, Teredo furcifera VON MARTENS and L. lignorum at Noto. Monthly settlement of shipworm larvae was determined by test panel method (pine wood, 5 × 20 × 2 cm) in which the number of borer apertures on wood surfaces was counted under stereo-microscope. Very light larval settlement was observed for only two months (September and October, 1974) at Onagawa. Shipworm attack on wood at Tatoku Island occurred for six months from June through November, 1974. The extent of larval settlement was very light, fewer than 10 borer apertures per 100 cm^2. Occurrence of larval settlement at Noto began in June when water temperature rose up to around 20℃, and continued for nine months with a peak in September, 1974. The more larval settlement was recorded on the lower surfaces than on the upper surfaces. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 39 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 33 59/60 Wood Research Institute, Kyoto University Studies on the Shipworms II : Monthly Settlement of Shipworm Larvae 2433/90331 Mihara, Takashi 1981/06/20 182 0527-2997 3 物性研究 181 36 物性研究刊行会 4.

The color difference caused by sunshine exposure was minimized at an acetylation level of 20% weight gain (WG) with a rapid decline from 10% WG, even though the exposure time was prolonged. Weathering led to early disintegration and enlargement of bordered pits, extensive separation of the latewood tracheid walls in the middle lamella and checkings oriented along the microfibril angle of the S_2 layer. These characteristic patterns of cell-wall erosion due to weathering were essentially the same in both untreated and acetylated wood. However, scanning electron microscope observations revealed that more extensive microscopic and macroscopic checks leading to distortion of the cell alignment appeared in untreated wood and wood which had been treated with a low-level of acetylation. For highly acetylated wood, severe intra- and inter- cell wall erosion was limited, and the original cell alignment was retained. However, after long-term exposure to natural weathering, the surface cell-layers of acetylated wood were defibrated separately and were attached to the unexposed cellular structure beneath them. This may explain the observation that acetylated wood has more severe surface-contamination than untreated wood, in which the new cell-layers appear successively because of the severe erosion of the exposed surfaces. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 61 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 54 79 Wood Research Institute, Kyoto University Acetylated wood Morphological Changes in Acetylated Wood Exposed to Weathering 2433/77485 Yan, Donghang 1993/02/26 442 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 435 70 Institute for Chemical Research, Kyoto University Electron Beam Radiation Damage and High-resolution Electron Microscopy of Poly(aryl-ether-ketone) Crystal 2433/51110 Iwatake, Atsuhiro 2006/08/31 37 1880-6503 Sustainable humanosphere : bulletin of Research Institute for Sustainable Humanosphere Kyoto University 37 2 Research Institute for Sustainable Humanosphere Kyoto University Mechanical properties of wood pulp/Poly Lactic Acid green-nano composites(ABSTRACTS (MASTER THESIS FOR GRADUATE SCHOOL OF AGRICULTURE)) 2433/51113 Sasaki, Kanako 2006/08/31 40 1880-6503 Sustainable humanosphere : bulletin of Research Institute for Sustainable Humanosphere Kyoto University 40 2 Research Institute for Sustainable Humanosphere Kyoto University Expression analyses and characterization of isoprene synthase from Populus alba(ABSTRACTS (MASTER THESIS FOR GRADUATE SCHOOL OF AGRICULTURE)) 2433/75840 Tsuji, Waichiro 1961/11/15 330 0023-6071 4-5 Bulletin of the Institute for Chemical Research, Kyoto University 330 39 Institute for Chemical Research, Kyoto University Spontaneous Extension of High Molecular Substances 2433/77270 Tahara, Yoshikazu 1989/03/15 604 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 598 66 Institute for Chemical Research, Kyoto University Direct Observation of Gold Sol by Cryo-Electron Microscopy (Commemoration Issue Dedicated to Professor Natsu Uyeda, on the Occasion of His Retirment) 2433/122552 高山, 秀則 1979/11/29 Spermatocytic seminoma was first described as a distinctive histologic variant of pure seminoma by Masson in 1946. Reported herein is a case of spermatocytic seminoma, being a very rare case in Japan. A 49-year-old man was hospitalized because of painless enlargement of left scrotal content. Left orchiectomy was done under a diagnosis of testicular tumor. A histologic study did not confirmed a sure diagnosis and even immature rhabdomyosarcoma was suspected at that time because of resembling histologic features. Retroperitoneal lymphadenectomy was performed and no lymphatic metastasis was proved. Eight months after the operation, the patient was again hospitalized because of an irregular surface of contralateral scrotal content. Right orchiectomy was again performed under a diagnosis of right testicular tumor. Detail histological examinations by light microscope and electron microscope showed pictures of spermatocytic seminoma in the bilateral testicular tumors. The patient is healthy after three years postoperative follow-up period with no evidence of metastatic disease. 1331 0018-1994 12 泌尿器科紀要 1327 25 泌尿器科紀要刊行会 NONSYNCHRONOUSLY GROWN BILATERAL SPERMATOCYTIC SEMINOMA: REPORT OF A CASE 非同時発生両側性Spermatocytic Seminomaの1例 2433/172574 2011/10/30 59 1342-0321 ICR annual report 58 19 Institute for Chemical Research, Kyoto University Photonic Elements Science 2433/172585 2011/10/30 37 1342-0321 ICR annual report 36 19 Institute for Chemical Research, Kyoto University Polymer Materials Science 2433/172604 2011/10/30 iii 1342-0321 ICR annual report iii 19 Institute for Chemical Research, Kyoto University Preface 2433/139914 Uchikawa, Toru 2011/04/01 Large vacuoles are characteristic of plant and fungal cells, and their origin has long attracted interest. The cellular slime mould provides a unique opportunity to study the de novo formation of vacuoles because, in its life cycle, a subset of the highly motile animal-like cells (prestalk cells) rapidly develops a single large vacuole and cellulosic cell wall to become plant-like cells (stalk cells). Here we describe the origin and process of vacuole formation using live-imaging of Dictyostelium cells expressing GFP-tagged ammonium transporter A (AmtA-GFP), which was found to reside on the membrane of stalk-cell vacuoles. We show that stalk-cell vacuoles originate from acidic vesicles and autophagosomes, which fuse to form autolysosomes. Their repeated fusion and expansion accompanied by concomitant cell wall formation enable the stalk cells to rapidly develop turgor pressure necessary to make the rigid stalk to hold the spores aloft. Contractile vacuoles, which are rich in H(+)-ATPase as in plant vacuoles, remained separate from these vacuoles. We further argue that AmtA may play an important role in the control of stalk-cell differentiation by modulating the pH of autolysosomes. 57 0012-1606 1 Developmental biology 48 352 Elsevier Inc.

Phase behavior of the LCs in the networks has also been observed. It has been found that the nematic-to-isotropic phase transition temperatures of the LCs in the networks (TNI g) are slightly (ca. 1K) lower than the ones of the corresponding pure LCs (TNI o), and that the depression degrees of TNI in each system are comparable in spite of large differences in Q between every system. In the temperature regions of TNI g σy)), is inversely derived by finite element method fitting the experimental results. The residual stress in each layer is experimentally examined, and the effect is included in the inverse analysis. We obtain σ = 3316ε0.29 [MPa] and a yield stress of 765 MPa for the Cu film. The yield stress is about 10 times higher than that of the bulk, and the exponent is also larger. Moreover, inverse analysis based on the bending experiment data, without considering the residual stress, gives a good approximation of the plastic law. This is because the plastic deformation preferentially takes place at the top and bottom surfaces, where the residual stress is relieved during fabrication of the specimen. 6047 0040-6090 21 Thin Solid Films 6040 518 Elsevier B.V.

Accordingly, we assessed the hypothesis that carvedilol may reduce the severity of atherosclerosis in apolipoprotein E (apoE)-deficient mice in addition to its hemodynamic effects. Atherosclerosis was induced in apoE-deficient mice fed a high-fat diet containing 0.3% cholesterol. Mice were orally treated with propranolol (30 mg/kg/day), metoprolol (75 mg/kg/day) and carvedilol (10 mg/kg/day) over eight weeks (each group n = 7-9). Fatty streak plaque developed in apoE-deficient mice, and was suppressed in mice treated with all three drugs. The accumulation of macrophages and expression of CD4(+) and CD8(+) cells in the lesions were decreased by the treatment of the drugs, of which carvedilol was the most effective. In addition, carvedilol reduced superoxide production in aortic walls detected by ethidium staining. There were no significant changes in blood pressure among the study groups. The heart rates in the treated groups were decreased by 4%-12% compared with the control group, with carvedilol yielding the highest suppression of heart rate. The β-blocker treatment did not significantly modify the serum lipid profiles. Carvedilol may suppress atherosclerosis via reducing superoxide production, in addition to the hemodynamic modifications in this animal model. 1044 1535-3702 9 Experimental biology and medicine 1039 237 Royal Society of Medicine Press Ltd atherosclerosis Carvedilol reduces the severity of atherosclerosis in apolipoprotein E-deficient mice via reducing superoxide production. 2433/147207 Satoh, Nobuo 2010/05/30 We demonstrated near-field light detection by dynamic force microscope using a self-sensing piezoelectric cantilever having a lead zirconate titanate thin film layer. The cantilever tip was brought close to a glass plate with a patterned chromium film on a right angle prism. The backside of the prism was irradiated by an intensity modulated laser light to create an evanescent field at the glass surface. We obtained near-field optical images of the patterned glass by detecting the frequency shift modulation or the amplitude modulation induced by the near-field light while the tip-sample distance was regulated by the frequency modulation method in ambient condition. 0003-6951 23 APPLIED PHYSICS LETTERS http://link.aip.org/link/APPLAB/v96/i23/p233104/s1 96 AMER INST PHYSICS Near-field light detection by conservative and dissipative force modulation methods using a piezoelectric cantilever 2433/76041 Uyeda, Natsu 1965/07/15 504 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 494 42 Institute for Chemical Research, Kyoto University Some Behavior and structures of Leaf-Like Crystals of Copper- and Zinc-Phthalocyanines vacuum-Deposited by Electron Bombardment (Special Issue on Electron Microscopy) 2433/76722 Ishizuka, Kazuo 1977/08/31 268 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 260 55 Institute for Chemical Research, Kyoto University Effects of the Dynamical Scattering on the Molecular Images in High Resolution Electron Microscopy (Commemoration Issue Dedicated to Professor Keinosuke Kobayashi on the Occasion of His Retirement) 2433/76086 Hosono, Kazuhiko 1966/02/28 329 0023-6071 4-5 Bulletin of the Institute for Chemical Research, Kyoto University 323 43 Institute for Chemical Research, Kyoto University Measurement of Absolute Energy Loss of 28 MeV Alpha Particles in Various Materials 2433/49903 Yamada, A 2005/05/30 0003-6951 22 APPLIED PHYSICS LETTERS http://link.aip.org/link/?apl/86/223901 86 AMER INST PHYSICS All-or-none switching of transcriptional activity on single DNA molecules caused by a discrete conformational transition 2433/87358 Ito, Yuichi 2006/12/30 We have studied the mechanism of the photoluminescence (PL) enhancement and quenching of single CdSe/ZnS core/shell nanocrystals on Au surfaces by means of single nanocrystal spectroscopy. The on-off PL blinking observed on the glass surface is drastically suppressed on Au surfaces, because of the fast energy transfer between Au surfaces and nanocrystals. The PL enhancement of single CdSe/ZnS nanocrystals occurs on rough Au surfaces, but PL quenching occurs on flat Au surfaces, compared to the case of the glass surface. Single nanocrystal spectroscopy reveals that the PL enhancement on rough Au surfaces is caused by the suppression of PL blinking and the electric field enhancement due to localized plasmon excitation. 1098-0121 3 Physical Review B 75 American Physical Society cadmium compounds Mechanism of photoluminescence enhancement in single semiconductor nanocrystals on metal surfaces 2433/87364 Ishizumi, Atsushi 2005/08/30 We have fabricated Mn-doped CdS (CdS:Mn) nanocrystals embedded in Al2O3 matrices by sequential ion implantation and studied their photoluminescence (PL) properties by a scanning near-field optical microscope (SNOM). In the PL spectra of CdS:Mn nanocrystals measured by the SNOM, several sharp PL lines and a broad PL band were observed. The sharp PL lines are related to bound excitons at shallow impurities in CdS nanocrystals. The Mn-related PL spectrum is very broad even in single nanocrystals at low temperatures, and both the peak energy and the spectral width of the PL band depend on the excitation laser intensity. The PL properties of single CdS:Mn nanocrystals are discussed. 0003-6951 13 Applied Physics Letters 87 American Institute of Physics Photoluminescence properties of single Mn-doped CdS nanocrystals studied by scanning near-field optical microscopy 2433/78103 Imai, Tomoya 2000/03/23 Kyoto University 天然セルロースミクロフィブリルにおけるナノドメイン構造 Nanodomain Structure of Native Cellilose Microfibril 2433/84593 Chen, Tao 2008/08/04 We reported on the fabrication of microchannels in the interior of silicon wafers using a femtosecond laser of 800 nm wavelength, which was in the absorption region of silicon. The scanning electron micrographs showed that microchannels were induced inside the silicon wafer when the femtosecond laser beam was focused inside the wafer. The aspect ratio of the microchannel cross section decreased with the increase in scan velocity of the laser. The formation of the photoinduced microchannels probably resulted from the microexplosions due to both the linear absorption and avalanche ionization. 0003-6951 5 APPLIED PHYSICS LETTERS http://link.aip.org/link/?APPLAB/93/051112/1 93 American Institute of Physics Photoinduced microchannels inside silicon by femtosecond pulses 2433/75489 Kikuchi, Takehiko 1954/10/30 11 0023-6071 s Bulletin of the Institute for Chemical Research, Kyoto University 4 32 Institute for Chemical Research, Kyoto University Paper II Studies on the Properties and Size of the Radioactive Ashes Obtained from the No. 5 Fukuryu Maru (The Radioactive Dust from the Nuclear Detonation) 2433/87368 Ishizumi, Atsushi 2004/02/28 We report on photoluminescence (PL) properties of Cu- and Al-doped ZnS nanocrystals fabricated by sequential implantation of Zn+, S+, Cu+, and Al+ ions into Al2O3 matrices. The spatially resolved PL spectrum has been studied by a scanning near-field optical microscope (SNOM). In the SNOM image, bright spots are observed on the sample surface. The PL spectrum at each bright spot is broad and is not sensitive to the monitored positions. The broad SNOM-PL spectrum at each spot is very similar to the macroscopic PL spectrum measured by conventional optics. The donor-acceptor pair luminescence process in nanocrystals is discussed. 0003-6951 13 Applied Physics Letters 84 American Institute of Physics Space-resolved photoluminescence of ZnS:Cu,Al nanocrystals fabricated by sequential ion implantation 2433/50581 Gotoh, Y 2007/05/14 0003-6951 20 APPLIED PHYSICS LETTERS http://link.aip.org/link/?apl/90/203107 90 AMER INST PHYSICS Derivation of length of carbon nanotube responsible for electron emission from field emission characteristics 2433/49731 Yamada, Ayako 2007/09/29 2218 14394227 18 Chembiochem 2215 8 John Wiley & Sons biomimetics Spontaneous Generation of Giant Liposomes from an Oil/Water Interface 2433/52902 UEYAMA, Akinori 1962/07/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 30 0049-7916 木材研究 : 京都大學木材研究所報告 24 28 京都大學木材研究所 木材のDimensional Stabilityに関する研究(第11報) : 強制腐朽試験に供した塩化水素 : ホルムアルデヒド処理材の組織内における菌糸の行動 Studies on the Dimensional Stabilization of Wood.

The major components of the end walls may be disintegrated enzymatically from their surfaces, but disintegration of the minor components (probably a part of cellulose micro-fibrils) may be achieved by the transpiration streams. In the case of intervessel pit membranes, it seems that only the non-cellulosic substances may be removed enzymatically. Parenchyma cells adjacent to vessels, having protective layers, seem to be got rid of the enzymatical attack through the vessel-parenchyma pit membranes. Considering the observation results by O'BRIEN (1970), it seems likely that the disintegration of unlignified cell walls is a general phenomenon that occurs later in the autolysis of the vessel elements. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 11 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 1 50 Wood Research Institute, Kyoto University Formation of Perforation Plates and Bordered Pits in Differentiating Vessel Elements 2433/77245 Kajiwara, Kanji 1989/02/15 175 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 165 66 Institute for Chemical Research, Kyoto University Lyotropic Mesophase Formation of Imogolite (Commemoration Issue Dedicated to Professor Hiroshi Ibagaki, Professor Michio Kurata, Professor Ryozo Kitamura, On the Occasion of Their Retirments) 2433/51703 OHKAWA, Kinichi 1965/08/30 (1) Comparative studies have been made on the inhibitory effects of phaspholipase A, phospholipase C and phospholipase D upon the activities of cytochrome cxidase, DPNH diaphorase, TPNH diaphorase, succinic dehydrogenase and malic dehydrogenase. (2) The inhibitory effect of phospholipase A was conspicuous, however those of phospholipase C and phospholipase D were weak.

The reduction process is monitored by an in situ measurement of a mixed potential. The mixed potential, which is above the redox potential of a Co(II)/Co redox pair, drops by the addition of the nucleating agent H2PtCl6 and also decreases with an increase in the H2PtCl6 concentration. Smaller Co nanoparticles are formed. In the smaller particle size, the fraction of the face-centered cubic Co phase increases, and the hexagonal close-packed Co phase decreases.

In these species, oocytes grew very rapidly from about 40 μm in diameter to about 75 μm (O. dioica) and 110 μm (O. longicauda), respectively within a few hr. Moreover, cutting off the gonads at the last phase of the growth stage yielded matured gametes. The eggs and sperm obtained by the dissection of gonads could be fertilized when they were mixed together. 727 0289-0003 5 Zoological Science 723 15 Zoological Society of Japan Rapid Oocyte Growth and Artificial Fertilization of the Larvaceans Oikopleura dioica and Oikopleura longicauda 2433/169115 Dietler, Giovanni 2009/04/20 Long double stranded DNA (dsDNA) and single stranded DNA (ssDNA) molecules were studied by direct imaging with the Atomic Force Microscope (AFM) in order to determine their scaling properties, exponents, distributions and persistence length in the frame work of the theory of polymer physics and at the single molecule level.

In this study, we aimed to establish a method for attaching cells to the substrate, in which the pattern is drawn by an inkjet printer. Poly-deoxyribonucleic acid (DNA) was immobilized onto the cell surface by use of DNA-conjugated poly(ethylene) glycol-phospholipid (DNA-PEG-lipid), which is the amphiphilic conjugate of PEG-lipid and single-stranded DNA. The surface of the substrate was then modified with the complementary DNA using an inkjet printer. Finally, DNA-immobilized cells were attached onto the substrate through DNA hybridization. The use of the inkjet printer enabled us to draw the DNA pattern accurately on the substrate with a resolution of a few hundred micrometers. DNA-immobilized cells could be attached precisely along the DNA pattern on the substrate. In addition, various kinds of cells could be attached simultaneously by using various sequences of DNA. Our technique is promising for analysis of cell-cell interactions and differentiation induction in stem cell research. 3602 1878-5905 14 Biomaterials 3596 32 Elsevier Ltd.

To elucidate the manner in which cell fates are established, single blastomeres of the two-cell stage embryos of the benthic arrow worm, Paraspadella gotoi, were injected with a fluorescent lineage-tracing dye. The distribution of labels was observed in the hatchlings by using a confocal laser scanning microscope. A total of four different labeling patterns was observed: 1) the dorsal epidermis, the right half of the ventral epidermis, and the right half of the dorsal longitudinal muscles (DR pattern); 2) the dorsal epidermis, the left half of the ventral epidermis, and the left half of the dorsal longitudinal muscles (DL pattern); 3) the right half of the ventral epidermis, the ventral longitudinal muscles, the right half of the dorsal body muscles, and the primordial germ cells (PGCs) (VR pattern); and 4) the left half of the ventral epidermis, the ventral longitudinal muscles, the left half of the dorsal body muscles, and the PGCs (VL pattern). Thus, one blastomere of the two-cell stage largely contributes the dorsal epidermis and the other contributes the ventral longitudinal muscles and the PGCs. Bilateral halves of the dorsal longitudinal muscles and the ventral epidermis were labeled as complementary pairs. These labeling patterns indicate that the first cleavage plane runs oblique to the bilateral and dorsoventral axes. In addition, the occurrence of complementary “DL and VR” and “DR and VL” labeling patterns indicates that the first cleavage plane bears one of two different angular relationships relative to the future body axes. 469 0289-0003 3 Zoological Science 459 16 Zoological Society of Japan Establishment of Axial Properties in the Arrow Worm Embryo, Paraspadella gotoi (Chaetognatha): Developmental Fate of the First Two Blastomeres 2433/171146 Lin, Aiming 2013/02/27 Field investigations, combined with meso- and microstructural analyses, reveal that numerous ultracataclastic veins are widely developed within a fault zone (<150 m wide) as simple veins, complex lenses, and networks, along active faults of the Arima–Takatsuki Tectonic Line, southwest Japan. These veins comprise mainly pseudotachylyte-like vein and weakly consolidated to unconsolidated fault gouge that is black, dark-brown, brown, gray, and brownish-red in color. Meso- and microstructural features show that these pseudotachylyte-like and fault gouge veins and networks formed during multiple stages, as earlier veins are generally cut and overprinted by younger veins, indicating that the vein-forming events occurred repeatedly and that ultracataclastic material was injected into networks of faults and fractures in the fault zone. The pseudotachylyte-like and fault gouge veins are characterized by an ultrafine- to fine-grained matrix and angular to subangular fragments of host granitic rocks of various sizes, ranging from submicron to millimeters. SEM–EDS (Scanning Electronic Microscope-Energy Dispersive X-ray) and powder X-ray diffraction analyses show that all the ultracataclastic veins are characterized by crystalline materials composed mainly of quartz and feldspar, similar to the host granitic rocks.The present results support the existing hypothesis that ultrafine- to fine-grained materials formed by comminution can be fluidized and injected rapidly into fracture networks located far from the source fault plane in a solid–fluid–gas system during seismic slip; therefore, such materials provide a record of paleoseismic faulting events that occurred repeatedly within the seismogenic fault zone. 13 0191-8141 Journal of Structural Geology 3 48 Elsevier Ltd.

In Takamatsu and Gomoris' methods the precipitates of calcium phosphate were transformed into silver or cobalt phosphate for visualization with light microscope. However, one step reaction is necessary to obtain exact cytochemical results for electron microscopy. Lead ions were first used by Molbert et al. as the capture reagent for this purpose. However, the reaction was carried out below pH 8 and diffusion seemed to occur. Deimling, her co-worker, described a modified lead method conducting the reaction at pH 8.2-9.2 with light microscopy. The present author also tried the lead method and found that the concentration of potassium sodium tartrate, the chelating reagent added to make lead ions stable in alkaline solution, is critical and they used too much tartrate. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 38 1 Acta tuberculosea Japonica 34 16 Tuberculosis Research Institute, Kyoto University MODIFICATION OF LEAD METHOD FOR DEMONSTRATION OF ALKALINE PHOSPHATASE ACTIVITY WITH LIGHTAND ELECTRON-MICROSCOPY 2433/77406 Iwauchi, Kozo 1991/12/30 382 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 375 69 Institute for Chemical Research, Kyoto University Dielectric Properties of α-Fe₂ 0₃ (Commemoration Issue Dedicated to Professor Tetsuya HANAI On the Occasion of His Retirement) 2433/39645 Chen, XQ 2001/06/04 3716 0003-6951 23 APPLIED PHYSICS LETTERS 3714 http://link.aip.org/link/?apl/78/3714 78 AMER INST PHYSICS Aligning single-wall carbon nanotubes with an alternating-current electric field 2433/49848 Ichikawa, M 2001/12/31 4600 0003-6951 27 APPLIED PHYSICS LETTERS 4598 http://link.aip.org/link/?apl/79/4598 79 AMER INST PHYSICS Optical transport of a single cell-sized liposome 2433/49849 Harada, T 2002/12/16 4852 0003-6951 25 APPLIED PHYSICS LETTERS 4850 http://link.aip.org/link/?apl/81/4850 81 AMER INST PHYSICS Mode switching of an optical motor 2433/47055 1978/08/20 0034-6675 1 The Review of Physical Chemistry of Japan 48 The Physico-Chemical Society of Japan Cover 2433/47077 1980/02/20 0034-6675 2 The Review of Physical Chemistry of Japan 49 The Physico-Chemical Society of Japan Cover 2433/47086 1979/10/30 0034-6675 The Review of Physical Chemistry of Japan 50 The Physico-Chemical Society of Japan Cover 2433/117013 三品, 輝男 1990/09/29 症例は58歳の男性,1986年8月,5年間続いた頻尿と高度の排尿障害のため三品泌尿器科を受診.直腸診にて,弾力硬,表面平滑な,くるみ大の左右対照的な前立腺を触知,経直腸的超音波断層撮影と逆行性尿道膀胱造影により膀胱内への小腫瘤の突出を確認し手術.腫瘍は,円柱上皮から成るcysticな腺成分の増生と巨細胞の混在した異型のある間葉系細胞の増生を認めphylloidestumorと診断.戻し電顕の結果,巨細胞は平滑筋由来であることが判明.術後3年以上経過するも経過は良好.前立腺に発生したphylloidcstumorの症例をreviewし,病理学的鑑別診断の要点を明らかにする. 1188 0018-1994 10 泌尿器科紀要 1185 36 泌尿器科紀要刊行会 Phylloides tumor A case report of phylloides tumor of the prostate: review of the literature and analysis of bizarre giant cell origin 前立腺に発生したphylloides tumorの一症例 2433/168457 1942/10/01 377 257 天界 = The heavens 376 22 東亞天文協會 標準天文用語表(11) 2433/77694 Takabe, Keiji 1985/01/23 Kyoto University 針葉樹仮道管における細胞壁成分の堆積 DEPOSITION OF CELL WALL COMPONENTS IN CONIFER TRACHEIDS 2433/139190 2010/10/30 11 1342-0321 ICR annual report 10 17 Institute for Chemical Research, Kyoto University Chemistry of Polymer Materials 2433/139167 2010/10/30 57 1342-0321 ICR annual report 56 17 Institute for Chemical Research, Kyoto University Photonic Elements Science 2433/139187 2010/10/30 17 1342-0321 ICR annual report 16 17 Institute for Chemical Research, Kyoto University Nanospintronics 2433/143419 Jill D.

We adopted a frequency modulation (FM) detection method not only to stabilize the imaging conditions in our DFM but also to enhance the sensitivity for the detection of electrostatic forces in KFM measurement. We deposited Alq3 [tris (8-hydroxyquinolinato) aluminum] thin films and aluminum (Al) electrode patterns on an indium tin oxide (ITO)/glass substrate by vacuum evaporation using shadow masks. The surface structures and local surface potential of Alq3 films on metals were investigated using our DFM/KFM instrument to study the local electrical properties at the molecule–metal interface. The photosensitive organic material sample can be in a completely dark environment because no optics are required for cantilever deflection sensing in our experimental setup. 0021-8979 11 Journal of Applied Physics 109 American Institute of Physics cantilevers Surface potential measurement of organic thin film on metal electrodes by dynamic force microscopy using a piezoelectric cantilever 2433/74464 Takagi, Hideo 1952/09/30 38 0023-6071 京都大学化学研究所報告 36 30 京都大学化学研究所 X-Ray Study on Thallium Foils 2433/75325 Suito, Eiji 1953/05/30 215 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 213 31 Institute for Chemical Research, Kyoto University Formation and Aging of Precipitates.

Initially, condensed DNA was stably grasped by a laser without any chemical modification and without physical attachment to an artificial object such as micro-plastic beads. Under optical transport, the trapped genome gradually unfolded in solution due to viscous friction. Interestingly, the nucleoid DNA from a log-phase cell is almost fully elongated, whereas in the stationary phase, unfolding of the nucleoid is characterized by step-wise elongation of 1.7–5.1 μm, corresponding to a size of 5–15 kbp, and a few tightly packed domains remain along the DNA chain. This suggests the coexistence of tightly packed and swollen domains in the genome in the stationary phase. article in press 176 01681656 2 Journal of Biotechnology 172 133 Elsevier Optical tweezers In situ analysis of the higher-order genome structure in a single Escherichia coli cell 2433/65329 ISODA, Seiji 2002/02/27 7 1342-0321 ICR annual report 6 8 Institute for Chemical Research, Kyoto University Effect of molecular packing efficiency on the epitaxial growth modes of monomolecular film on graphite sudied by STM / Lattice defects in organic crystals revealed by derect molecular imaging (STATES AND STRUCTURES - Electron Microscopy and Crystal Chemistry) 2433/65367 2003/02/27 11 1342-0321 ICR annual report 10 9 Institute for Chemical Research, Kyoto University Molecular Aggregates 2433/65370 2003/02/27 5 1342-0321 ICR annual report 4 9 Institute for Chemical Research, Kyoto University Electron Microscopy and Crystal Chemistry 2433/53106 TABATA, Yasunori 2003/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 12 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 11 90 Wood Research Institute, Kyoto University Aloeswood Structural Survey and Artificial Induction of Aloeswood 2433/53108 SYAFWINA, SYAFWINA 2002/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 20 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 19 89 Wood Research Institute, Kyoto University empty fruit bunch Pre-treatment of Oil Palm Empty Fruit Bunch by White-rot Fungi for Enzymatic Saccharification 2433/49185 Ichikawa, Masatoshi 2007/09/29 Thermal convection and thermophoresis induced by µm-scale local heating are shown to elongate a single DNA molecule. An infrared laser used as a point heat source is converged into a dispersion solution of DNA molecules, which is observed under a fluorescent microscope. The thermal convection around the laser focus manifests as extensional flow for the long DNA chain. A simulation of thermal convection that reproduces the experimental condition provides numerical support for the stretching caused by thermal convection. This DNA elongation technique is a novel method for manipulating the intact single DNA molecules, and it can be applied to a “lab on a chip”. 00319007 Physical Review Letters 148104 99 American Physical Society Extension of a DNA Molecule by Local Heating with a Laser 2433/53127 SHIMOO, Tsuyoshi 2002/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 16 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 15 89 Wood Research Institute, Kyoto University cellulose synthase Expression of Cellulose synthase fused to Green Fluorescent Protein in the Tobacco Suspension-cultured Cells 2433/76721 Shimamura, K. 1977/08/31 272 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 269 55 Institute for Chemical Research, Kyoto University Observation of Deformation Process of Polyethylene with an X-Ray TV System (Commemoration Issue Dedicated to Professor Keinosuke Kobayashi on the Occasion of His Retirement) 2433/52342 1971/01/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 5 0009-3378 1 京都大学結核胸部疾患研究所紀要 1 4 京都大学結核胸部疾患研究所 English abstracts 2433/53390 1974/08/31 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 72 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 70 57 Wood Research Institute, Kyoto University Abstracts 2433/52308 KANAMURA, Shinsuke 1972/03/31 A fixation technique for the ultrastructural observation of the lung is presented.

By steam-explosion hemicelluloses were rapidly hydrolyzed to lower molecular weight products. Almost all hemicelluloses (27.9%) in Shirakanba wood were hydrolyzed to oligosaccharides to be extracted with water by only one min. steaming at 20 kg/cm^2, and 53.7% of hemicelluloses were converted to monosaccharides by 8 min. steaming at 28 kg/cm^2. Monosaccharides obtained by 2 min. steaming at 28 kg/cm^2 of Shirakanba wood were composed of 61.1% of xylose and only 4.9% of glucose, and the yields were in accord with original composition of hardwood hemicelluloses. Cellulose in non-crystalline area was partially hydrolyzed, and micelle length was decreased to about 2000 Å by 8 min. steaming at 28 kg/cm^2. However, cellulose was not hydrolyzed to glucose, and non-crystalline cellulose would be annealed and transformed to crystalline celluslose. Thus the crystallinity and micelle width of cellulose were increased by steam explosion treatment. However, when reaction time was increased, the yields of furfural and 5-hydroxymethylfurfural derived from polysaccharides were increased. Lignin was degraded slower than hemicelluloses. The yield of lignin was 29.2% in maximum by 8 min. steaming at 28 kg/cm^2, and the molecular weight of lignins obtained were decreased to Mw=2100 and 1100 by 2 min. and 16 min. steaming, respectively. A degradation mechanism of lignin by steam explosion was presumed to be homolytic cleavage of aryl ether linkage. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 12 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 1 75 Wood Research Institute, Kyoto University steam explosion Characterization of Steam-Exploded Wood II : Chemical Changes of Wood Components by Steam Explosion 2433/84987 2008/10/30 15 1342-0321 ICR annual report 14 15 Institute for Chemical Research, Kyoto University Inorganic Photonics Materials 2433/84966 2008/10/30 57 1342-0321 ICR annual report 56 15 Institute for Chemical Research, Kyoto University Photonic Elements Science 2433/84972 2008/10/30 45 1342-0321 ICR annual report 44 15 Institute for Chemical Research, Kyoto University Laser Matter Interaction Science 2433/77280 1989/03/15 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 66 Institute for Chemical Research, Kyoto University 植田夏教授略歴 Emeritus Professor Natsu Uyeda, Cover & Contents 2433/53209 MATUMAE, Tomoyuki 1996/08/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 32 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 30 83 Wood Research Institute, Kyoto University wood identification The Composition of Tree Species in the Forest Buried by the Aso-4 Pyroclastic Flow : Identification of Wooden Remains Excavated from Yato Relics in Saga Prefecture 2433/53190 IMAI, Tomoya 1997/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 30 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 28 84 Wood Research Institute, Kyoto University cellulose Iα Structure Determination of Cellulose Microfibrils in the Cell Wall of Cladophora 2433/53174 KIYOSHIGE, Mariko 1998/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 70 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 68 85 Wood Research Institute, Kyoto University auxin The Effect of Auxin on the Polarity of Tracheid Arrangement in Pinus Thunbergii 2433/53150 HIKAWA, Yoshinobu 2000/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 38 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 37 87 Wood Research Institute, Kyoto University hexaflumuron Effect of Hexaflumuron on the Two Major Japanese Subterranean Termites, Coptotermes formosanus Shiraki and Reticulitermes speratus (Kolbe) 2433/53165 MURASE, Koichi 1999/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 50 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 49 86 Wood Research Institute, Kyoto University carbonization Changes to the Permeability of Wood Resulting from Carbonization 2433/75841 Kitamaru, Ryozo 1961/11/15 330 0023-6071 4-5 Bulletin of the Institute for Chemical Research, Kyoto University 329 39 Institute for Chemical Research, Kyoto University The Preparation of Some New Synthetic Fibers from Polyvinyl Alcohol by Mixed Emulsion Spinning 2433/76618 O'Nrien, Neal R. 1975/09/25 76 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 71 53 Institute for Chemical Research, Kyoto University Experimental Results of an SEM Study of Clay Fabric (Commemoration Issue Dedicated to Professor Eiji Suito on the Occasion of his Retirement) 2433/50093 Takahashi, K 2000/10/30 2060 0734-2101 5 JOURNAL OF VACUUM SCIENCE & TECHNOLOGY A-AN INTERNATIONAL JOURNAL DEVOTED TO VACUUM SURFACES AND FILMS 2055 19 AMER INST PHYSICS Solid particle production in fluorocarbon plasmas.

An octadecyltrimethoxysilane (ODS) monolayer, self-assembled on an indium tin oxide (ITO) surface, was exposed to VUV light (172 nm) through a photomask to construct the linear pattern by photodegradation of the ODS monolayer. Subsequently, an aminopropyltriethoxysilane (APS) monolayer was deposited on VUV-exposed sites by chemical vapor deposition. The immobilization of AuNPs on amino-terminated sites is due to the electrostatic attraction between citrate-stabilized AuNPs and amino groups of the APS monolayer, while the methyl-terminated sites remain unexposed. The structural organization of AuNPs in an alternating linear fashion was demonstrated by scanning electron microscope (SEM) analysis. The X-ray photoelectron microscopy (XPS) measurements were performed to probe the self-assembly of ODS, the APS monolayer, photopatterning and AuNPs immobilization. 5052 0021-4922 6 Japanese Journal of Applied Physics 5048 47 Japan Society of Applied Physics indium tin oxide Spatially Controlled Functionalization and Chemical Manipulation to Fabricate Two-Dimensional Arrays of Gold Nanoparticles onto Indium Tin Oxide 2433/95791 Okada, Motoyuki 1996/06/20 この論文は国立情報学研究所の電子図書館事業により電子化されました。 509 0527-2997 3 物性研究 508 66 物性研究刊行会 MOLECULAR WEIGHT DEPENDENCE OF LATERAL GROWTH RATE OF A SINGLE CRYSTAL OF POLYETHYLENE(Session III : Complex Fluids, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations) 2433/95843 Miyakawa, Kenji 1996/06/20 この論文は国立情報学研究所の電子図書館事業により電子化されました。 377 0527-2997 3 物性研究 376 66 物性研究刊行会 SYNCHRONIZATION AND CHAOS IN THE DISCRETE CHEMICAL OSCILLATION SYSTEM(Session I : Cross-Disciplinary Physics, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations) 2433/108568 Hori, Michio 2007/04/29 Antisymmetry in the direction of the mouth opening, to either the right (“lefty”) or left (“righty”), was documented in the scale-eating cichlid Perissodus microlepis. This study revealed the presence of lefty and righty mouth morphs in the herbivorous cichlid Neolamprologus moorii, although the degree of deviation was not large. Both species are biparental brooders and guard their young. We examined the inheritance pattern of the dimorphism (laterality) using parents and broods of P. microlepis and N. moorii collected in the wild. In P. microlepis, lefty-lefty pairs had a 2:1 frequency of lefty:righty young, lefty-righty pairs a similar number of each type of young, and righty-righty pairs only righty young. Similar inheritance patterns were observed in N. moorii. We propose two hypotheses to explain the inheritance pattern: Mendelian genetics with the lefty allele dominant over the righty and the dominant allele homozygous lethal, and cross-incompatibility that is predominant in lefty homozygotes. 492 0289-0003 5 Zoological Science 486 24 Zoological Society of Japan Inheritance Pattern of Lateral Dimorphism in Two Cichlids (a Scale Eater, Perissodus microlepis, and an Herbivore, Neolamprologus moorii) in Lake Tanganyika 2433/108334 2009/10/30 45 1342-0321 ICR annual report 44 16 Institute for Chemical Research, Kyoto University Laser Matter Interaction Science 2433/108328 2009/10/30 57 1342-0321 ICR annual report 56 16 Institute for Chemical Research, Kyoto University Photonic Elements Science 2433/109943 Tsukimoto, Susumu 2009/04/29 Growth and microstructure of ternary Ti3SiC2 compound layers on 4H-SiC, which play am important role in formation of TiAl-based ohmic contacts to p-type SiC, were investigated in this study. The Ti3SiC2 layer was fabricated by deposition of Ti/Al contacts (where a slash “/” indicates the deposition sequence) on the 4H-SiC(0001) substrate and subsequent rapid thermal anneal at 1000°C in ultra high vacuum. After annealing, reaction products and microstructure of the Ti3SiC2 layer were investigated by X ray diffraction analysis and transmission electron microscopy observations in order to understand the growth processes of the Ti3SiC2 layer and determination of the Ti3SiC2/4H-SiC interface structure. The Ti3SiC2 layers with hexagonal plate shape were observed to grow epitaxially on the SiC(0001) surface by anisotropic lateral growth process. The interface was found to have a hetero-epitaxial orientation relationship of (0001)TSC||(0001)S and [0\bar110]TSC||[0\bar110]S where TSC and S represent Ti3SiC2 and 4H-SiC, respectively, and have well-defined ledge-terrace structures with low density of misfit dislocations due to an extremely low lattice mismatch of 0.4% between Ti3SiC2 and 4H-SiC. 1075 1345-9678 5 MATERIALS TRANSACTIONS 1071 50 Japan Institute of Metals Ti3SiC2 Growth and Microstructure of Epitaxial Ti3SiC2 Contact Layers on SiC 2433/123406 Yamasue, Kohei 2009/08/24 We successfully demonstrated the first experimental stabilization of irregular and non-periodic cantilever oscillation in the amplitude modulation atomic force microscopy using the time-delayed feedback control. A perturbation to cantilever excitation force stabilized an unstable periodic orbit associated with nonlinear cantilever dynamics. Instead of the typical piezoelectric excitation, the magnetic excitation was used for directly applying control force to the cantilever. The control force also suppressed the cantilever's occasional bouncing motions that caused artifacts on a surface image. 3144 0375-9601 35 Physics Letters A 3140 373 Elsevier Controlling chaos Controlling chaos in dynamic-mode atomic force microscope 2433/172579 2011/10/30 49 1342-0321 ICR annual report 48 19 Institute for Chemical Research, Kyoto University Electron Microscopy and Crystal Chemistry 2433/160364 Arioka, Yuko 2012/09/17 Activation-induced cytidine deminase (Aid), a unique enzyme that deaminates cytosine in DNA, shuttles between the nucleus and the cytoplasm. A recent study proposed a novel function of Aid in active DNA demethylation via deamination of 5-hydroxymethylcytosine, which is converted from 5-methylcytosine by the Ten-eleven translocation (Tet) family of enzymes. In this study, we examined the effect of simultaneous expression of Aid and Tet family proteins on the subcellular localization of each protein. We found that overexpressed Aid is mainly localized in the cytoplasm, whereas Tet1 and Tet2 are localized in the nucleus, and Tet3 is localized in both the cytoplasm and the nucleus. However, nuclear Tet proteins were gradually translocated to the cytoplasm when co-expressed with Aid. We also show that Aid-mediated translocation of Tet proteins is associated with Aid shuttling. Here we propose a possible role for Aid as a regulator of the subcellular localization of Tet family proteins. 1932-6203 9 PloS one 7 Public Library of Science Activation-induced cytidine deaminase alters the subcellular localization of tet family proteins. 2433/65600 Ogawa, Hiroki 2008/07/23 Kyoto University Polymer blend 高分子ブレンド薄膜における相分離と脱濡れ Phase Separation and Dewetting in Polymer Blend Thin Films 2433/169680 Yoshida, Aya 2012/01/02 Diabetes mellitus is characterized by an impairment of glucose uptake even though blood glucose levels are increased. Methylglyoxal is derived from glycolysis and has been implicated in the development of diabetes mellitus, because methylglyoxal levels in blood and tissues are higher in diabetic patients than in healthy individuals. However, it remains to be elucidated whether such factors are a cause, or consequence, of diabetes. Here, we show that methylglyoxal inhibits the activity of mammalian glucose transporters using recombinant Saccharomyces cerevisiae cells genetically lacking all hexose transporters but carrying cDNA for human GLUT1 or rat GLUT4. We found that methylglyoxal inhibits yeast hexose transporters also. Glucose uptake was reduced in a stepwise manner following treatment with methylglyoxal, i.e. a rapid reduction within 5 min, followed by a slow and gradual reduction. The rapid reduction was due to the inhibitory effect of methylglyoxal on hexose transporters, whereas the slow and gradual reduction seemed due to endocytosis, which leads to a decrease in the amount of hexose transporters on the plasma membrane. We found that Rsp5, a HECT-type ubiquitin ligase, is responsible for the ubiquitination of hexose transporters. Intriguingly, Plc1 (phospholipase C) negatively regulated the endocytosis of hexose transporters in an Rsp5-dependent manner, although the methylglyoxal-induced endocytosis of hexose transporters occurred irrespective of Plc1. Meanwhile, the internalization of hexose transporters following treatment with methylglyoxal was delayed in a mutant defective in protein kinase C. 711 0021-9258 1 The Journal of biological chemistry 701 287 American Society for Biochemistry and Molecular Biology hexose transporter Reduction of glucose uptake through inhibition of hexose transporters and enhancement of their endocytosis by methylglyoxal in Saccharomyces cerevisiae. 2433/139380 TANAKA, Yuriko 2011/02/27 159 0084-5515 ZINBUN 147 42 Jinbun kagaku Kenkyusho, Kyoto University Koch’s Technologies and Postulates: How They Work Together in Connecting the Material and the Human in the Foundation of Bacteriology 2433/76952 Chen, Guan-Wen 1981/11/30 283 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 267 59 Institute for Chemical Research, Kyoto University Microheterophase Structure, Permeability, and Biocompatibility of A-B-A Tri-Block Copolymer Membranes Composed of Poly (γ-ethyl L-glutamate) as the A Component and Polybutadiene as the B Component (Special Issue on Polymer Chemistry, XVI) 2433/160661 Tsunemi, Eika 2011/02/27 We developed a dual-probe (DP) atomic force microscopy (AFM) system that has two independently controlled probes. The deflection of each cantilever is measured by the optical beam deflection (OBD) method. In order to keep a large space over the two probes for an objective lens with a large numerical aperture, we employed the OBD sensors with obliquely incident laser beams. In this paper, we describe the details of our developed DP-AFM system, including analysis of the sensitivity of the OBD sensor for detection of the cantilever deflection. We also describe a method to eliminate the crosstalk caused by the vertical translation of the cantilever. In addition, we demonstrate simultaneous topographic imaging of a test sample by the two probes and surface potential measurement on an α-sexithiophene (α-6T) thin film by one probe while electrical charges were injected by the other probe. 0034-6748 3 REVIEW OF SCIENTIFIC INSTRUMENTS http://link.aip.org/link/?rsi/82/033708 82 American Institute of Physics atomic force microscopy Development of dual-probe atomic force microscopy system using optical beam deflection sensors with obliquely incident laser beams 2433/169726 Ikeda, Toru 2012/12/30 Numerical methods like the finite element (FE) method are often used to evaluate the reliability of electronic packages. However, the accuracy of non-linear numerical analyses should be confirmed by experimental measurements. In this study, we evaluated the strain distribution in flip chip (FC) packages with multi-layered printed circuit boards (PCBs) by combining the digital image correlation method (DICM) and the non-linear FE method, considering the viscoelasticity of resins and the elastoplasticity and creep of solder alloy. Four types of FC package consisting of two types of buildup (BU) resin and two types of underfill (UF) resin were evaluated. The distributions of strain on the cutting sections of FC packages were measured using the DICM with microphotographs obtained by a confocal laser scanning microscope (CLSM). The strain measurements showed that the UF resin with the low coefficient of thermal expansion (CTE) reduced thermal strain around a solder bump, and the BU resin with the low CTE reduced the strain concentration along the interface between a Si chip and a solder bump. We performed the non-linear FE analyses while taking into account the viscoelastic Poisson’s ratio of the UF resin and the constant instantaneous Poisson’s ratio. The result of the FE analyses with the constant instantaneous Poisson’s ratio did not correspond with the strain measurements using the DICM. The normal strain in a solder bump was less than that obtained by the measurement, and the direction of a shear strain band in a solder bump was different from that measured using the DICM. On the other hand, the FE analyses considering the viscoelastic Poisson’s ratio showed good agreement with the strain measurements using the DICM. The strain measurement using the DICM improved the accuracy of the non-linear FE analysis of microelectronic packages effectively. 153 0026-2714 1 Microelectronics Reliability 145 53 Elsevier Ltd.

Here, we focused on integrin-mediated cell-scaffold adhesion and prepared cell adhesive fibroin in which a tandem repeat of the Arg-Gly-Asp-Ser (RGDS) sequence was genetically interfused in the fibroin light chain (L-chain) (L-RGDSx2 fibroin). We investigated the effects of the sequence on chondrocyte adhesion and cartilage synthesis, in comparison to the effects of fibronectin. As the physicochemical surface properties (e.g., wettability and zeta potential) of the fibroin substrate were not affected by the modification, specific cell adhesion to the RGDS predominately changed the chondrocyte adhesive state. This suggestion was also supported by the competitive inhibition of chondrocyte attachment to the L-RGDSx2 fibroin substrate with soluble RGD peptides in the medium. Unlike fibronectin, the expression of RGDS in the fibroin L-chain had no effect on chondrocyte spreading area but enhanced mRNA expression levels of integrins alpha5 and beta1, and aggrecan at 12 h after seeding. Although both the sequence and fibronectin increased cell adhesive force, chondrocytes grown on the fibroin substrate exhibited a peak in the force with time in culture. These results suggested that moderate chondrocyte adhesion to fibroin induced by the RGDS sequence was able to maintain the chondrogenic phenotype and, from the histology findings, the sequence could facilitate chondrogenesis. 7511 0142-9612 29 Biomaterials 7503 31 Elsevier Ltd Cell adhesion Effects of RGDS sequence genetically interfused in the silk fibroin light chain protein on chondrocyte adhesion and cartilage synthesis. 2433/86411 Maruyama, Keizo 1966/03/23 Kyoto University 花粉形成時における細胞内膜系の行動 Behavior of membrane system in the cell during microsporogenesis 2433/91250 Sugano, Shigeo S 2009/12/09 Stomata in the epidermal tissues of leaves are valves through which passes CO(2), and as such they influence the global carbon cycle. The two-dimensional pattern and density of stomata in the leaf epidermis are genetically and environmentally regulated to optimize gas exchange. Two putative intercellular signalling factors, EPF1 and EPF2, function as negative regulators of stomatal development in Arabidopsis, possibly by interacting with the receptor-like protein TMM. One or more positive intercellular signalling factors are assumed to be involved in stomatal development, but their identities are unknown. Here we show that a novel secretory peptide, which we designate as stomagen, is a positive intercellular signalling factor that is conserved among vascular plants. Stomagen is a 45-amino--rich peptide that is generated from a 102-amino-acid precursor protein designated as STOMAGEN. Both an in planta analysis and a semi-in-vitro analysis with recombinant and chemically synthesized stomagen peptides showed that stomagen has stomata-inducing activity in a dose-dependent manner. A genetic analysis showed that TMM is epistatic to STOMAGEN (At4g12970), suggesting that stomatal development is finely regulated by competitive binding of positive and negative regulators to the same receptor. Notably, STOMAGEN is expressed in inner tissues (the mesophyll) of immature leaves but not in the epidermal tissues where stomata develop. This study provides evidence of a mesophyll-derived positive regulator of stomatal density. Our findings provide a conceptual advancement in understanding stomatal development: inner photosynthetic tissues optimize their function by regulating stomatal density in the epidermis for efficient uptake of CO(2). 葉の気孔の数を増加させる因子の発見～CO2削減や食糧増産へ向けて～. 京都大学プレスリリース. 2009-12-10. http://www.kyoto-u.ac.jp/ja/news_data/h/h1/news6/2009/091210_1.htm 244 1476-4687 Nature 241 463 Stomagen positively regulates stomatal density in Arabidopsis. 2433/128866 Sumigawa, Takashi 2010/09/25 In order to investigate the fatigue behavior of metals in nanoscale, a cyclic bending experiment is carried out using a nano-specimen. The specimen includes a copper film with a thickness of 20 nm constrained by highly rigid materials, which yields a high strain region with a size of a few nanometers near the interface edge. The specimen broke before the maximum load in the 7th cycle under fatigue (load range of 18 μN). The load-displacement curve shows nonlinear behavior and a distinct hysteresis loop, indicating plasticity in the Cu film. Reverse yielding appearing after the 2nd cycle suggests the development of a cyclic substructure in the Cu film. The cumulative plastic strain in the Cu film at fracture is more than three times larger than that under monotonic loading. These results indicate that the specimen breaks owing to fatigue of the Cu film on the nanoscale. 6523 0921-5093 24-25 Materials Science and Engineering: A 6518 527 Elsevier B.V.

First, the stones were studied using a scanning electron microscope and bacteriological method. Most of the stone cores consisted of calcium phosphate and organic materials containing bacteria, fibrin, erythrocytes, leukocytes and so on. Second, in experimental ascending pyelonephritis in rats which received the intravesical instillation of Proteus mirabilis, the incidence of renal stone formation was increased with the grade of the pyelonephritis and necrotic papillae played an important role as stone nuclei. Third, urinary materials, which may initiate and accelerate stone formation, were investigated using the urine of stone formers associated with renal infections, nucleopore filters and stitches, from the standpoint of crystal aggregation and adhesion effects. The bacteria tended to aggregate crystalline and organic matters in the urine and to adhere them to the stitches before the crystals. The results obtained suggest that the bacteria and organic matters in the urine of stone formers participate actively in stone genesis and growth as an adhesive agent. 1391 0018-1994 8 泌尿器科紀要 1387 31 泌尿器科紀要刊行会 Infection Renal infections and implicated urinary stone formation 感染と尿路結石形成 2433/139157 2010/10/30 98 1342-0321 ICR annual report 95 17 Institute for Chemical Research, Kyoto University Selected Grants 2433/148416 Matsuoka, Tomoyo 2009/10/30 Maskless and electroless patterning of gold was performed by a simple method: 3-mercaptopropyltrimethoxysilane (MPTMS) and an aqueous solution of hydrogen tetrachloroaurate (HAuCl4·4H2O) were reacted, and the obtained solution was dropped onto a silicon substrate processed by a focused ion beam (FIB). This method utilizes the selective growth of gold nanoparticles on an FIB-processed area of a silicon surface. Raman microspectroscopy revealed that gold nanoparticles selectively grew on an FIB-processed area when an amorphous silicon phase was induced by an FIB. Unlike other attempts to fabricate metal patterns with silane coupling agents, MPTMS acts as a reducing agent, not as glue. 578 1882-0743 1379 JOURNAL OF THE CERAMIC SOCIETY OF JAPAN 575 118 CERAMIC SOC JAPAN-NIPPON SERAMIKKUSU KYOKAI Metal patterning Selective growth of gold nanoparticles on FIB-induced amorphous phase of Si substrate 2433/75536 1956/03/30 100 0023-6071 1-2 Bulletin of the Institute for Chemical Research, Kyoto University 95 34 Institute for Chemical Research, Kyoto University A List of Scientic Papers : Published in Other Journals by the Staff of the Institute and their Co-workers during the Year 1955 2433/151987 Chen, Hao 2011/09/26 Kyoto University Islet 人工膵臓開発における高分子材料の応用 Application of polymer materials for development of artificial pancreas 2433/151703 Takaoka, Gikan H. 2011/10/30 The irradiation of Si(100) surfaces by ethanol cluster ion beams exhibited high-rate sputtering and low-damage formation. The sputtered depth increased with increase of the acceleration voltage for ethanol cluster ions, and the sputtering yield was a few hundreds times larger than that by Ar monomer ion beams. Also, the RBS channeling measurement showed that the irradiation damage was much less than that by Ar monomer ion irradiation. Furthermore, the AFM image showed that the surface roughness of the irradiated Si(100) surface was less than 1 nm. As well as the Si(100) surface, the sputtered depth of the photo-resist surface increased with increase of the acceleration voltage for ethanol cluster ions. Based on these results, micro-patterning with various sizes in a range of 3 μm to 100 μm was performed on the Si(100) surfaces by the ethanol cluster ion irradiation. Various kinds of photo-resist mask patterns such as circle, square and line patterns were made on a Si(100) surface by photo-resist technique. The SEM observation showed that micro-patterns were prepared on the Si (100) surface by the ethanol cluster ion irradiation. 873 0257-8972 5 Surface and Coatings Technology 869 206 Elsevier B.V.

At the substrate temperature of 420 °C, the Ge nanowhiskers grow on the sample deposited at the deposition angle of α = 85°, whereas no long nanowhisker grows on the samples deposited at α ≤ 73°. The kinetic growth model that takes into account the directional incidence of the vapor flux agrees with the experimental results and suggests that the atoms deposited on the side surface of the nanowhiskers play an essential role in the HT-GLAD assisted VLS growth. Supplying the atoms on the side surface of the nanowhiskers is expected to accelerate the growth of the nanowhiskers in any vapor phase growth methods, such as molecular beam epitaxy and chemical vapor deposition. 0003-6951 22 Applied Physics Letters 99 American Institute of Physics elemental semiconductors Vapor-liquid-solid growth of Ge nanowhiskers enhanced by high-temperature glancing angle deposition 2433/49880 Nomura, SM 2002/03/04 0031-9007 9 PHYSICAL REVIEW LETTERS http://link.aps.org/abstract/PRL/v88/p093903 88 AMERICAN PHYSICAL SOC Autonomous swinging of a lipid tubule under stationary irradiation by a Nd3+: YAG laser 2433/87345 Matsunaga, Ryusuke 2008/09/29 We studied exciton structures and the Aharonov-Bohm effect in a single carbon nanotube using micro-photoluminescence (PL) spectroscopy under a magnetic field at low temperatures. A single sharp PL peak from the bright exciton state of a single carbon nanotube was observed under zero magnetic field, and the additional PL of dark exciton state appeared below the bright exciton peak under high magnetic fields. It was found that the split between the bright and dark exciton states is several millielectron volts at zero field. The tube diameter dependence of the splitting arises from the intervalley short-range Coulomb interaction. 0031-9007 14 Physical Review Letters 101 American Physical Society Evidence for dark excitons in a single carbon nanotube due to the Aharonov-Bohm effect 2433/87344 Yoshikawa, Kohei 2009/02/27 We studied the temperature and chirality dependence of the photoluminescence (PL) linewidth of single carbon nanotubes to clarify the mechanism of exciton dephasing. The PL linewidth of a single carbon nanotube broadened linearly with increasing temperature, indicating that the linewidth and exciton dephasing are determined through exciton-phonon interactions. From the chirality dependence of the PL linewidth, we concluded that exciton dephasing is caused by both the longitudinal acoustic and twisting phonon modes. 0003-6951 9 Applied Physics Letters 94 American Institute of Physics Mechanism of exciton dephasing in a single carbon nanotube studied by photoluminescence spectroscopy 2433/157611 Asakawa, Harutoshi 2012/03/26 Kyoto University Isotactic polypropylene メゾ相経由のアイソタクチックポリプロピレンの巨大単結晶の形成 Formation of Giant Single Crystals of Isotactic Polypropylene via Mesophase 2433/141948 Taguchi, Ayako 2011/02/27 The dependence of the deformation change on the location and number of cells during water adsorption was examined by microscopy combined with a “charged-coupled device” camera and image analysis based on the digital image correlation method. The deformation change ratio (DCR) vs. moisture content (MC) in the radial direction approached linearity with MC with increasing in number of cells between measurement points in earlywood, whereas its relation in latewood was various such as swelling, swelling after shrinking, or remaining constant with MC. The number of cells between observation points clearly affected the DCR vs. MC, i.e., its relationship had the so-called “scale effect” that a certain physical property appears clearly with increasing scale. The mechanism of the scale effect differed in the radial and tangential directions. 256 0018-3830 2 Holzforschung 253 65 Walter de Gruyter anisotropy swelling Scale effect in the anisotropic deformation change of tracheid cells during water adsorption 2433/87360 Inoue, Tadashi 2006/05/30 We have investigated the diameter dependence of the exciton luminescence linewidth in individual single-walled carbon nanotubes (SWNTs) by means of microphotoluminescence (µ-PL) spectroscopy. The line shapes of µ-PL spectra for single SWNTs suspended on a patterned Si substrate at room temperature can be fitted by single Lorentzian functions. It is found that the µ-PL linewidth depends strongly on the diameter of SWNTs and the exciton-phonon interaction is enhanced with a decrease of the diameter. 1098-0121 23 Physical Review B 73 American Physical Society Diameter dependence of exciton-phonon interaction in individual single-walled carbon nanotubes studied by microphotoluminescence spectroscopy 2433/87357 Ueda, Akihiro 2008/03/30 We studied photoluminescence (PL) and energy transfer dynamics in CdSe nanocrystal (NC) assembled monolayers on Au surfaces. The close-packed CdSe NC monolayers were fabricated using the Langmuir–Blodgett method on spin-coated inert polymer films on rough-surface Au substrates. The PL intensity and PL decay time were dependent on the distance between the CdSe NCs and Au surfaces. These observations indicate that the metal-semiconductor distance and the luminescence-energy dependences of the energy transfer rate can be understood in terms of the Coulomb interaction between excitons in NCs and plasmons on the Au surfaces. 0003-6951 13 Applied Physics Letters 92 American Institute of Physics Energy transfer from semiconductor nanocrystal monolayers to metal surfaces revealed by time-resolved photoluminescence spectroscopy 2433/49172 SAEKI, Daisuke 2005/12/30 We investigated the kinetics of domain growth on liposomes caused by decreasing the temperature; the liposomes consisted of a ternary mixture (unsaturated phospholipid, saturated phospholipid, and cholesterol). The domain-growth process was monitored by fluorescence microscopy, and the growth was mediated by fusing the domains through collisions. It was found that an average domain size r develops with time t as r ∼t0.15. This indicates that the exponent is about half of that deduced from the theoretical analysis of a model of the Brownian motion on a two-dimensional membrane. We discuss the mechanism of the experimental scaling behavior by considering the elasticity of the membrane. 0031-9015 1 Journal of the Physical Society of Japan 013602 75 The Physical Society of Japan giant vesicle Domain-Growth Kinetics in a Cell-sized Liposome 2433/143574 Iwahashi, Seita 2010/10/30 We have successfully generated vector beams with higher-order polarization states using photonic-crystal lasers.

In dilute DNA conditions, individual DNA assumes a compact state via a discrete coil-globule transition, whereas in concentrated solution, DNA molecules exhibit an extended conformation via macroscopic phase segregation. The long-axis length of the stretched state in DNA is about 10(3) times larger than that of the compact state. Phase segregation at high DNA concentrations occurs at lower PEG concentrations than the compaction at low DNA concentrations. These opposite changes in the conformation of DNA molecule are interpreted in terms of the free energy, including depletion interaction.

On the other hand, in the stage of secondary wall thickening, cytoplasm is poor in amoeboid plastids and lipid droplets, but rich in smooth- and rough-surfaced ER. The fact that microtubules alter their orientation from perpendicular to parallel to the cell axis in the course of transition from primary to. secondary wall deposition suggests that microtubules are responsible for the orientation of microfibril. Through secondary wall growth, vesicle-secreting ability of Golgi bodies seems to be very poor. In view of almost all cellulose that composes the cell wall components of cotton fiber, Golgi-derived vesicles could not excrete cellulose precursor to the wall. It was found that smooth-surfaced ER (SER) is derived from RER during the secondary wall thickening. In addition, vesicles (larger than Golgi-derived vesicles) and cisternae of SER appear most frequently near the plasmalemma and seems to be incorporated into the cell wall. Consequently, a close correlation between SER and wall synthesis is presumed in the development of cotton fiber.

For the light polarized along the major axis of the nanorods, the plasma resonance of the Ag nanorods has been tuned to a wavelength suitable for Raman spectroscopy. The average width and the length-to-width ratio of the resulting nanorods are 56 nm and 3.5, respectively, and the nanorods align in line with small gaps of a few 10 nm. The Raman scattering for the polarized light along the nanorods is enhanced significantly as compared with that perpendicular to the nanorods. This polarization dependent Raman enhancement is attributed to the local field concentration at the ends of the nanorods. Since the preparation process is physical and completely bottom up, it is robust in its selection of the materials and is useful in providing the surface-enhanced Raman scattering sensors at low cost. ©2006 American Institute of Physics 0003-6951 20 Applied Physics Letters http://link.aip.org/link/?apl/88/203121 88 American Institute of Physics In-line aligned and bottom-up Ag nanorods for surface-enhanced Raman spectroscopy 2433/24203 Fujihira, K 2002/03/04 1588 0003-6951 9 Applied Physics Letters 1586 http://link.aip.org/link/?apl/80/1586 80 American Institute of Physics High-purity and high-quality 4H-SiC grown at high speed by chimney-type vertical hot-wall chemical vapor deposition 2433/24186 Suzuki, Motofumi 2006/09/25 The authors demonstrate the growth of unusual Al whiskers by glancing angle deposition on a high temperature (HT-GLAD) substrate, while the usual columnar structures completely disappear due to accelerated surface diffusion.

Using a near-field optical setup we investigated the photoluminescence maps with a polarization-modulation method. If the optical emissions have a preferred polarization orientation, our apparatus yields a signal that is proportional to the degree of polarization. We could demonstrate that within the quantum well there are localized submicrometer centers that emit strongly oriented light. This points toward the existence of quantum-dot like confined asymmetric domains hidden within the quantum well. 0003-6951 21 APPLIED PHYSICS LETTERS http://link.aip.org/link/APPLAB/v95/i21/p211904/s1 95 American Institute of Physics gallium compounds Near-field evidence of local polarized emission centers in InGaN/GaN materials 2433/109814 Le, Nam Cao Hoai 2009/11/29 We report a dual-color total-internal-reflection (TIR)-based chip that can generate two overlapping evanescent fields with different wavelengths for simultaneous imaging of two types of fluorophores. We derived a general relationship among the dimensions of the components of the chip to guarantee the overlap of two evanescent fields. Optical simulation results also confirm the generation and overlap of two evanescent fields. Using Si bulk micromachining and poly(dimethylsiloxane) (PDMS) casting, our fabrication method integrates all miniaturized optical components into one monolithic PDMS chip. Thus, assembly is unnecessary, and misalignment is avoided. Our PDMS chip can be employed with various sample delivery platforms, such as glass slide, flow cell, microchannel, etc. We first demonstrated the capability of the chip by imaging TIR fluorescent spots of a mixture of two fluorophores, namely, fluorescein and tetramethylrhodamine. We then employed the chip to observe the Brownian motion of a mixture of nile-red and dragon-green 500-nm microbeads. Our chip could potentially be integrated into a micro-total analysis system for highly sensitive and high-resolution dual-fluorescence imaging applications. 1381 1057-7157 6 JOURNAL OF MICROELECTROMECHANICAL SYSTEMS 1371 18 IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Dual-color total-internal-reflection fluorescent microscopy (TIRFM) A Monolithic Dual-Color Total-Internal-Reflection-Based Chip for Highly Sensitive and High-Resolution Dual-Fluorescence Imaging 2433/122523 武藤, 浩 1979/09/29 The ureteral epithelium of male adult rabbits was observed with a scanning electron microscope and the following results regarding the developmental changes were obtained. 1. The ureteral epithelium changes remarkably in form developmentally or on account of mechanical depression or traction. 2. The epithelium which developed in the basement membrane seems to be a ridge toward to the longitudinal direction of the ureter. 3. In the next stage, these cells develop in columnar form and touch with the basement membrane directly or indirectly through another cells. These cells seems to be a pseudostratified epithelium, because they are isolated from other surrounding cells. 4. The epithelial cell with a pointed end matures and it transforms into a flattened one approaching to the inner surface of the ureter. 5. It has become obvious that the covering epithelium of the ureter is a transitional type. Because, numerous furrows are observed on the surface of the covering epithelium reached to the inner surface of the ureter. These furrows indicate the elasticity of the cell. 1014 0018-1994 10 泌尿器科紀要 1009 25 泌尿器科紀要刊行会 DEVELOPMENTAL PROCESSES OF THE EPITHELIUM IN THE URETER OF RABBITS 家兎尿管粘膜上皮細胞の発生的変化 2433/122471 Kawamura, Nobuo 1979/06/29 男子尿性器由来の陸トリコモナス保存株を経代培養すると，薬剤に対する感受性が変化し，経代を重ねるほどMICが低下する。つまり薬剤が効きやすくなることが判明した。 またin vitroでの薬剤効果と臨床効果にも差のあることが判明した。したがって，膣トリコモナスの薬剤感受性を測定し， それを臨床的に利用しようとするには， 1. 経代数については，なるべく代数を重ねない株がよい。2. 培地，虫体数などは，常に一定する, ということが必要であることがわかっているが, さらに, 3. 臨床無効例より検出した虫体の感受性の検討，および誌験管内感受性との間の差がなぜ起こるかについての検討。 4. 耐性獲得という現象が本当にあるのか? 5. 男子尿性器へ薬剤が如何なる濃度で分布するか，また膣トリコモナスが，どこに感染するか? 等についての追及が必要となろう。　それには，資料として，男子TV感染者の発見と，その株の保存が大切である。本論文の要旨は第22回日本化学療法学会総会において発表した。 656 0018-1994 7 泌尿器科紀要 651 25 泌尿器科紀要刊行会 抗腟トリコモナス剤の試験管内効力測定法に関する研究 STUDIES OF METHODS OF MEASURING IN VITRO EFFECTS OF DRUGS FOR VAGINAL TRICHOMONIASIS 2433/163459 Wu, Nan 2011/10/30 Periodic nanostructures were observed on the Ti thin film surface after irradiation with a focused beam of femtosecond Ti:sapphire laser. It has been found which, on the ablated Ti thin film surface, the linearly polarized femtosecond laser pulses produced arrays of ripple-like periodic nanostructures that were oriented to the direction parallel to the laser polarization, and a net-like nanostructure was fabricated on the surface of Ti thin film by the technique of two linearly polarized femtosecond laser beams with orthogonal polarizations ablating material alternately. The period of self-organized ripple-like nanostructures can be controlled by the pulses energy and the number of irradiated pulses. The result suggests that the formation of periodicity can be attributed to the excitation of surface Plasmon polarizations which induce initial period distribution of the electron plasma concentration orientation parallel to the light polarization on the surface layer. The estimated field period was in general accord with the observed size of nanostructures. 901 1882-0743 1395 JOURNAL OF THE CERAMIC SOCIETY OF JAPAN 898 https://www.jstage.jst.go.jp/article/jcersj2/119/1395/119_1395_898/_article/-char/ja/ 119 The Ceramic Society of Japan(日本セラミックス協会) Femtosecond laser Nano-periodic structure formation on titanium thin film with a Femtosecond laser 2433/163777 Kobayashi, Masaru 2011/09/29 In plant cells, boron (B) occurs predominantly as a borate ester associated with rhamnogalacturonan II (RG-II), but the function of this B-RG-II complex has yet to be investigated. 3-Deoxy-D-manno-2-octulosonic acid (KDO) is a specific component monosaccharide of RG-II. Mutant plants defective in KDO biosynthesis are expected to have altered RG-II structure, and would be useful for studying the physiological function of the B-RG-II complex. Here, we characterized Arabidopsis CTP:KDO cytidylyltransferase (CMP-KDO synthetase; CKS), the enzyme activating KDO as a nucleotide sugar prior to its incorporation into RG-II. Our analyses localized the Arabidopsis CKS protein to mitochondria. The Arabidopsis CKS gene occurs as a single-copy gene in the genome, and we could not obtain cks null mutants from T-DNA insertion lines. Analysis using +/cks heterozygotes in the quartet1 background demonstrated that the cks mutation rendered pollen infertile through the inhibition of pollen tube elongation. These results suggest that KDO is an indispensable component of RG-II, and that the complete B-RG-II complex is essential for the cell wall integrity of rapidly growing tissues. 1843 0032-0781 10 Plant & cell physiology 1832 52 Oxford University Press Arabidopsis Characterization of Arabidopsis CTP:3-deoxy-D-manno-2-octulosonate cytidylyltransferase (CMP-KDO synthetase), the enzyme that activates KDO during rhamnogalacturonan II biosynthesis. 2433/123398 Hayashi, Yuji 2009/04/24 We performed polarized optical microscope (POM), depolarized light scattering (DPLS) and small- and wide-angle X-ray scattering measurements on the structure formation process or the crystallization process of isotactic polystyrene (iPS) under shear flow below and above the nominal melting temperature Tm. It was found that an anisotropic oriented structure termed here as a string-like object was formed in μm scale even above the nominal melting temperature and stable for more than 24 h, but melted at around 270 °C far above the nominal melting temperature. The string-like object acts as a nucleation agent for the folded chain lamella crystal (or the kebab), and was assigned to a precursor of the shish–kebab. We also examined the shear rate dependence of the structure formation to find a critical shear rate for the formation of the string-like object, suggesting the relaxation of the chains plays an important role in the formation of the structure. Based on the results we have discussed the inner structure of the string-like object. 2103 0032-3861 9 Polymer 2095 50 Elsevier Precursor Precursor of shish–kebab in isotactic polystyrene under shear flow 2433/139251 Chen, Youqing 2011/02/02 To examine the fatigue process of granite, cylindrical Westerly granite specimens, 10 mm in diameter and 20 mm in length, were subjected to a cyclic loading test under uniaxial compression with a maximum of 140 MPa at room temperature, and crack growth patterns within them were analyzed by microscopic observation and image analysis techniques. The fatigue process is divided into three characteristic stages; a primary stage in which the upper peak strain increases at a decelerating rate (stage I), a second stage with linearly slight increasing rate of strain following stage I (stage II), and the third and final stage in which the upper peak strain increases at an accelerating rate and culminates in specimen failure (stage III). A series of prefailure specimens, of which the stage in the fatigue process was decided by monitoring the strain behavior during the test, were retrieved. In addition, these specimens were compared with specimens stressed to close to the breaking strength by monotonic compression to examine the characteristic features of fatigue. The fluorescent method was applied to identify microcracks within the specimens. The advantage of this method is to provide quick and accurate identification of microcracks with an optical microscope. Microcracks are detected based on a marked difference in brightness under ultraviolet light irradiation because they are fully filled with acrylic resin mixed with a fluorescent substance in advance. Thin sections, including the axis of the specimen, 10 × 20 mm, were prepared for detailed observation after the pretreatment of the method. The results were as follows. At the initial degradation stage, distinguishing crack growth was identified in quartz grains. It is estimated that the slowdown of the strain growth rate at this stage was caused by the decrease in crack growth, that is, the portions with cracking potentiality were damaged at the first or early loading, and no further damage occurred immediately following the first damage. At the second stage, no significant crack growth in quartz grains was identified. On the other hand, in feldspar grains, development of cracks in a preferential direction, parallel to the loading direction, was observed. However, they did not grow into intergranular cracks by cutting across the grain boundaries during this stage. Consequently, it was found that a gradual progress of microcracks within feldspar grains was dominant during the second stage, and this is because the strain growth rate was in a steady and long state. At the final accelerated stage, many intergranular cracks running parallel to the loading direction were identified. It is obvious that these long cracks were formed mainly by the linking and growth of the intragranular cracks in feldspars, which were generated during the former stages. Their formation takes the fatigue process from the second stage to the final stage with a sharp increase in strain, and their further development seemed to lead the whole specimen to ultimate fatigue failure. 197 0013-7952 3-4 Engineering Geology 189 117 Elsevier B.V. Microcrack Crack growth in Westerly granite during a cyclic loading test 2433/138082 Sakakura, Masaaki 2010/12/30 The femtosecond laser induced structural modification was studied by the detection of a laser induced pressure wave using a transient lens (TrL) method. The TrL signals observed at various excitation pulse energies showed that there were two thresholds of the pulse energy for the modification. Above the higher threshold, a pressure wave was observed clearly, and the amplitude of the pressure wave increased with increasing excitation pulse energy. In addition, Raman spectra at the laser irradiated region showed that the compact silica ring structures increased in the photoexcited region above the higher threshold, which suggested that the photoexcited glass was densified by a shock due to a pressure wave generation. In the energy region between the lower and higher thresholds, a pressure wave was not detected but a temporally constant refractive index change was observed. From the amplitude of the change, the temperature elevation just after the photoexcitation in this energy region was estimated to be about 1400 K. We interpreted that fast cooling from the high temperature is responsible for the modification between the lower and higher thresholds. The two modifications identified in this study should correspond to two types of damage inside a silica glass which have been observed previously. This is the first study that elucidated the difference of two types of modification from the time-resolved observation of the dynamics. 0021-8979 2 Journal of Applied Physics 109 American Institute of Physics glass Thermal and shock induced modification inside a silica glass by focused femtosecond laser pulse 2433/75537 1956/03/30 94 0023-6071 1-2 Bulletin of the Institute for Chemical Research, Kyoto University 92 34 Institute for Chemical Research, Kyoto University Titles of Papers : Read at the 56th Semi-annual Meeting of the Institute on November 18th and 19th, 1955 2433/153252 2010/05/30 75 1348-317X 低温物質科学研究センター誌 : LTMセンター誌 40 16 低温物質科学研究センター -Summaries <特集>-発表要旨集より 2433/75866 Sakka, Sumio 1962/03/25 411 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 410 39 Institute for Chemical Research, Kyoto University The Effects of Heat Treatment on the Strength of Polycrystalline Material Produced from the Glass of the System Li₂O-MgO-A1₂O₃-SiO₂ 2433/75867 Sakka, Sumio 1962/03/25 410 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 409 39 Institute for Chemical Research, Kyoto University Studies on the Devitrification of the Glasses of the System Li₂O-ZnO-Al₂O₃-SiO₂ 2433/75985 1964/02/25 247 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 245 41 Institute for Chemical Research, Kyoto University 1962 : Physical Chemistry 2433/154869 Doi, Norio 2011/04/04 The objective of this study is to design biodegradable nanospheres of cationized gelatin as a carrier of cellular internalization of plasmid DNA. Ethylenediamine was chemically introduced into the carboxyl groups of gelatin to obtain cationized gelatin. The gelatin solution was filtered through a glass membrane under high pressure and dropped into 2-butanol, acetone or a mixture of the two to form nanospheres of cationized gelatin. The microspheres of cationized gelatin were prepared by the conventional water-in-oil emulsion method. The resulting nano- and microspheres of cationized gelatin were dehydrothermally treated at 160°C for different time periods to allow them to cross-link chemically. The size of nanospheres, prepared by the filtration method and changed by the type of solvents, was 1.86, 0.83 or 0.24 μm. The in vitro degradation of spheres became faster as the time period of dehydrothermal treatment was shorter. The degradation time of spheres in HCl solution linearly increased with an increase in the cross-linking time, irrespective of the sphere size. However, in the collagenase solution, when compared at the similar cross-linking density, the smaller spheres were degraded more slowly than the larger ones. The plasmid DNA incorporated in the nanospheres was released from the nanospheres with their degradation. The nanospheres incorporating plasmid DNA were internalized into cells, and intracellularly degraded with time to release plasmid DNA. The time period of plasmid DNA release was prolonged by increasing the nanosphere degradation time. 1004 1568-5624 8 Journal of biomaterials science.

In this study, the roles of auxin in nodule development in Lotus japonicus have been demonstrated using molecular genetic tools and auxin inhibitors. The expression of an auxin-reporter GH3 fused to β-glucuronidase (GUS) was analyzed in L. japonicus roots, and showed a strong signal in the central cylinder of the root, whereas upon rhizobium infection, generation of GUS signal was observed at the dividing outer cortical cells during the first nodule cell divisions. When nodules were developed to maturity, strong GUS staining was detected in vascular tissues of nodules, suggesting distinct auxin involvement in the determinate nodule development. Numbers and the development of nodules were affected by auxin transport inhibitors (1-naphthylphthalamic acid, NPA and triindobenzoic acid, TIBA), and by a newly synthesized auxin antagonist, α-(phenyl ethyl-2-one)-indole-3-acetic acid (PEO-IAA). The common phenotypical alteration by these auxin inhibitors was the inhibition in forming lenticel which is normally developed on the nodule surface from the root outer cortex. The inhibition of lenticel formation was correlated with the inhibition of nodule vascular bundle development. These results indicate that auxin is required for the normal development of determinate nodules in a multidirectional manner. 81 0032-0935 1 Planta 73 234 Springer-Verlag Involvement of auxin distribution in root nodule development of Lotus japonicus. 2433/75486 Kikuchi, Takehiko 1954/10/30 34 0023-6071 s Bulletin of the Institute for Chemical Research, Kyoto University 29 32 Institute for Chemical Research, Kyoto University Paper V Radioautographic Studies of the Materials Obtained from the No. 5 Fukuryu Maru Contaminated by Radioactive Ashes (The Radioactive Dust from the Nuclear Detonation) 2433/76396 Tanaka, Nobuyuki 1972/02/29 381 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 377 49 Institute for Chemical Research, Kyoto University Thermal Shrinkage of Polyethylene Terephthalate Fibers Swollen in Acetone-Water Mixtures 2433/65393 2004/02/28 45 1342-0321 ICR annual report 44 10 Institute for Chemical Research, Kyoto University Molecular Biology 2433/65235 Hirai, Asako 2000/02/28 Structures of cellulose assemblies produced by Acetobacter xylinum under various conditions have been studied mainly by transmission electron microscopy. Native cellulose crystals are composites of cellulose Iα and Iβ . Twisted-ribbn cellulose assemblies produced in the HS medium at 28 °C were rich in cellulose Iα . On the contrary, splayed microfibrils produced in the presence of CMC at 28 °C were rich in Iβ . Not only the ribbon assembly but also the bundle of splayed microfibrils was determined to twist in the right-handed manner. When the bacteria were incubated at 4 °C, two kinds of band-like assemblies, “dense” and “coarse”, were extruded perpendicularly to the long axis of bacterial cells. The number of cellulose chains produced by one bacterium was different between “dense” and “coarse” assemblies. The “dense” assembly gave the electron diffraction pattern of cellulose II. In certain cases the transition region from dense to coarse portions was observed in one assembly. Initially a “dense” portion was produced and thereafter a “coarse” portion was produced. The number of cellulose synthesis sites seems to decrease, because a bacterium becomes less active after a certain period of time at 4 °C. 29 1342-0321 ICR annual report 28 6 Institute for Chemical Research, Kyoto University Bacterial cellulose Cellulose Assemblies Produced by Acetobacter Xylinum (FUNDAMENTAL MATERIAL PROPERTIES-Molecular Dynamic Characteristics) 2433/65247 Tsujimoto, Masahiko 2000/02/28 For fine particles of semiconductive rutile TiO2 supporting ultra-fine particles of Pt which were prepared by decomposing a colloidal organic-Pt complex, the structural aspects of the high photoactivity were examined by high resolution imaging, X-ray mapping by energy dispersive spectroscopy and electron energy-loss spectroscopy. As a result, the Pt particles with nm-sizes were found to grow epitaxially on rutile, which supports an expected mechanism that the photo-excited electrons efficiently transfer from TiO2 to Pt and promote the reduction of O2 to O2 -. 7 1342-0321 ICR annual report 6 6 Institute for Chemical Research, Kyoto University Decomposing organic-platinum colloid TEM Analysis of Pt-particles Embedded on TiO2 Exhibiting High Photocatalytic Activity (STATES NAD STRUCTURES-Crystal Information Analysis) 2433/65287 Tosaka, Masatoshi 2001/02/27 The crystal transformation in lamellar crystals of polybutene-1 grown from an amyl acetate solution was studied by cryogenic high-resolution transmission electron microscopy. The shape of the transformed trigonal (form-1) crystal domains in the surrounding tetragonal (form-2) crystal was successfully revealed. Along with the nucleation of "untwinned" form-1, the existence of another nucleation mechanism which creates "twinned" form-1 was suspected. The growth of form-1 crystal was thought to progress not stem by stem but by pulling in the molecular chains from the surrounding form-2, creating new stems of form-1. The shape of the form-1 domain was irregular, and no specific crystallographic direction along which the form-1 domain tends to grow was found. 9 1342-0321 ICR annual report 8 7 Institute for Chemical Research, Kyoto University Transmission electron microscopy High-Resolution Observation of Crystal Transformation in Isotactic Polybutene-1 Single Crystals (STATES AND STRUCTURES-Polymer Condensed States) 2433/53092 FUJISAWA, Masashi 2003/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 16 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 15 90 Wood Research Institute, Kyoto University wood charcoal Development of SiC/C Composite Materials from Wood Charcoal by a Pulse Current Sintering Method and Their Properties 2433/53116 NAKAHARA, Susumu 2002/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 36 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 35 89 Wood Research Institute, Kyoto University Kraft pulp Development of Environmentally-Friendly and High-Strength Kraft Pulp Fiber Based Materials 2433/65159 Terashima, Takahito 1998/02/27 Single crystals of the heavily Pb-substituted Bi-2201 phase were grown to a typical planar shape of 6 x 3 x 0.03 mm3 by using a floating zone method [1]. These crystals with the highest Pb content ever reported are free from any structural modulation as examined by transmission electron microscopy, and the orthorhombic lattice parameters are a = 5.300(3) A, b = 5.392(3) A, and c = 24.603(5) A (V = 703.2 A3). Their superconducting properties can be modified within the over-doped region in such a way that the transition temperature, Tc, is raised from 3 K for the as-grown crystals to 23 K by annealing at 550 °C for 2 weeks in a vacuum of ~10-4 Pa. The out-of-plane resistivity of the as-grown crystals remains metallic down to 20 K, while it becomes semiconductive below 160 K after the annealing. 19 1342-0321 ICR annual report 18 4 Institute for Chemical Research, Kyoto University Bi-2201 Growth of heavily Pb-substituted Bi-2201 single crystals by a floating zone method (SOLID STATE CHEMISTRY-Artificial Lattice Compounds) 2433/65166 Ogawa, Tetsuya 1998/02/27 The crystal structure of C60 at liquid helium temperature was examined by electron diffraction method using an imaging plate and cryo-TEM.

Theoretical treatment based on our structure model of the fault well explained the characteristic features of the electron diffraction patterns. Then the probability of presence of the fault was estimated for each Tc by measauring the mean half-breadth of the streaked reflections in the patterns. The probability thus estimated was in good agreement with that obtained from the number of the faults in a unit length: the number was counted directly in the high-resolution and/or the dark-field images taken by transmission electron microscopy. 9 1342-0321 ICR annual report 8 3 Institute for Chemical Research, Kyoto University Syndiotactic polystyrene Quantification of Stacking Faults in b-Form Single Crystals of Syndiotactic Polystyrene (STATES AND STRUCTURES-Polymer Condensed States) 2433/51688 NAGAISHI, Chuzo 1966/11/29 Histological observation suggests that the cuboid cell of adenomatous hyperplasia originates from pre-existing lining cell of the healthy alveolus. The resemblance in the fine structure of the cuboid cell to that of the alveolar wall cell (type B epithelial cell) provides strong evidence that the alveolar wall cell proliferates in response to pathogenic stimuli and forms the adenomatous hyperplasia in the alveolar area. Furthermore, it is suggested that the alveolar wall cell might play an improtant role in the carcinogenesis of some peripheral lung cancer. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 56 2 Acta tuberculosea Japonica 48 16 Tuberculosis Research Institute, Kyoto University HISTOLOGICAL AND ELECTRON MICROSCOPIC OBSERVATION ON THE ADENOMATOUS HYPERPLASIA OF THE ALVEOLAR EPITHELIAL CELL IN THE HUMAN LUNG 2433/51710 OKADA, Yoshio 1962/03/30 Chronic pulmonary emphysema is one of the most common chronic diseases of the lung. It may be defined as a condition of the lung characterized by abnormal increase in size of the air space distal to the terminal bronchioles either from dilatation or from destruction of their walls. Until recently much attention has been paid to the morphological changes of the alveolar walls and the disturbances of respiratory function in this disease, but the relationship between the morphological changes and the functional disturbances of the lung has not yet been clarified. It is now possible to demonstrate the fine structure of the alveolar walls in the normal and the diseased lung with electron microscopes. This paper reports observations of the fine structure of the alveolar walls in the pulmonary emphysema, and collates the findings with the results of function tests. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 62 2 Acta tuberculosea Japonica 57 11 Tuberculosis Research Institute, Kyoto University ELECTRON MICROSCOPIC OBSERVATION OF CHRONIC PULMONARY EMPHYSEMA 2433/53132 KAWAMURA, Shinya 2001/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 55 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 54 88 Wood Research Institute, Kyoto University physiological stress Effects of Physiological Stresses on Respiration Rates and Methane Emission Rates by the Termite, Coptotermes formosanus Shiraki 2433/46770 Minomura, Shigeru 1959/12/26 26 0034-6675 1 The Review of Physical Chemistry of Japan 22 29 The Physico-Chemical Society of Japan Studies on arsenic sulfide glass 2433/49855 Iwataki, T 2004/02/22 4011 0021-9606 8 JOURNAL OF CHEMICAL PHYSICS 4004 http://link.aip.org/link/?jcp/120/4004 120 AMER INST PHYSICS Competition between compaction of single chains and bundling of multiple chains in giant DNA molecules 2433/50359 Nagahama, T 2000/05/01 5650 0021-8979 9 JOURNAL OF APPLIED PHYSICS 5648 http://link.aip.org/link/?jap/87/5648 87 AMER INST PHYSICS Electric resistance of magnetic domain wall in NiFe wires with CoSm pinning pads 2433/46642 Fujii, Seiiti 1947/09/15 157 0034-6675 The Review of Physical Chemistry of Japan 153 20 The Physico-Chemical Society of Japan Methylol condensation of acetaldehyde (Commemoration volume dedicated to Prof. Shinkichi Horiba in celebration of his sixtieth birthday) 2433/95784 Onuki, Akira 1996/06/20 We first examine the condition of bicontinuity in spinodal decomposition in two component fluids.

C. insulicola has elaborate genitalia, in which the strongly sclerotized male copulatory piece is inserted into the female vaginal appendix in copula. During mating, I observed pre-copulatory struggles of males and females, as well as delays in ejaculation, suggesting the presence of intersexual conflicts. Insemination was achieved with a spermatophore, which strongly adhered to the openings of the spermatheca, common oviduct, and vaginal appendix. The spermatophore dissolved after copulation, and sperm were transferred into the spermatheca within three hours after copulation. Sperm bundles were contained within the testes and spermatophores, but free spermatozoa were found in the spermatheca. 1073 0289-0003 9 Zoological Science 1067 19 Zoological Society of Japan Mating Behavior, Insemination and Sperm Transfer in the Ground Beetle Carabus insulicola 2433/110083 Baigl, Damien 2004/12/20 この論文は国立情報学研究所の電子図書館事業により電子化されました。 417 0727-2997 3 物性研究 416 83 物性研究刊行会 28.

For these experiments, we calculated the grazing rates from the digestion rate of C. triciliatum and its food vacuole contents. During the study period, M. aeruginosa exhibited one bloom event with a maximum density of 1.1 × 10[5] cells ml[−1]. The cell density of C. triciliatum fluctuated from below the detection limit to 291 cells ml[−1]. The number of M. aeruginosa cells ingested by C. triciliatum food vacuoles ranged between 0.4 and 10.8 cells flagellate[−1], and the digestion rate of C. triciliatum at 25 °C was 0.73 % cell contents min[−1]. The grazing rate of C. triciliatum on the M. aeruginosa prey was 0.2–6.9 cells flagellate[−1] h[−1], and its grazing impact was 0.0–25.3 % standing stock day[−1]. The functional response of C. triciliatum to the M. aeruginosa prey followed the Michaelis–Menten model of significance (r[2] = 0.873, p < 0.001) in our experimental systems, in which the prey concentration varied from 1.0 × 10[4] to 2.1 × 10[6] cells ml[−1]. The maximum grazing rate was 6.2 prey cells grazer[−1] h[−1], and the half-saturation constant was 1.2 × 10[5] cells ml[−1]. We present evidence that C. triciliatum grazing explained the remarkable decrease in M. aeruginosa cell density in the pond. The present study is the first demonstration of the high potential of protistan grazing on M. aeruginosa to reduce cyanobacterial blooms. 49 1439-8621 1 Limnology 43 14 Springer Japan Microcystis aeruginosa Grazing impact on the cyanobacterium Microcystis aeruginosa by the heterotrophic flagellate Collodictyon triciliatum in an experimental pond 2433/131816 Takatsu, Hiroshi 2010/11/15 We report details of single crystal growth of the metallic triangular-lattice antiferromagnet PdCrO2 consisting of layers of Pd triangles and Cr triangles stacking along the c-axis. We used the NaCl flux method and obtained the crystals with the size as large as 2×3.5×0.3 mm3. We confirmed that single crystals have the delafossite structure with the View the MathML source symmetry. The electrical resistivity along the c-axis and that in the ab plane exhibit metallic temperature dependence with the anisotropic ratio ρc/ρab of over 300 at low temperatures. The residual resistivity of as small as View the MathML source and the residual resistivity ratio of over 100 indicate high quality of the crystals investigated. Nevertheless, there is no sign of superconductivity down to 0.3 K. These crystals are useful for the investigation of anisotropic magnetic and transport properties including the unconventional anomalous Hall effect (AHE). 3465 0022-0248 23 Journal of Crystal Growth 3461 312 Elsevier B.V.

Low dimensional structures Single crystal growth of the metallic triangular-lattice antiferromagnet PdCrO2 2433/148430 Ochiai, Shojiro 2009/10/30 The change of Young's modulus with increasing applied tensile strain in the open cell nickel and copper foams, fabricated by the slurry foaming process at Mitsubishi Materials Corporation, Japan, was investigated experimentally and analytically. Stress-strain curves were measured at room temperature, in which the loading-unloading-reloading process was performed on the sample at various applied strains. For measurement of the strain of the sample itself accurately, the non-contact extensometer was employed. The Young's modulus values at various applied tensile strains were estimated from the slope of the elastic region in the stress-strain curve in the unloading process. It was revealed that two competitive factors affect on the Young’ modulus value. One is the irreversible morphology-change of cells arising from the plastic deformation of the metal as a results of which, the cells are elongated and struts are straight forwarded in the tensile direction. This factor acts to raise the Young’s modulus with increasing applied strain. Another factor is the failure of struts, which tends to reduce the Young's modulus with increasing applied strain, especially beyond the strain where the struts are failed successively. Accordingly, due to the competition of the former and latter factors, the Young's modulus increases, reaching maximum and then decreases with increasing applied strain in both of the foams. The increase in Young's modulus with increasing applied strain due to the change of geometry of struts was confirmed by the experimental test of micro-samples composed of several struts and nodes and by the simulation based on the finite element analysis using a model micro-sample. 932 1345-9678 5 MATERIALS TRANSACTIONS 925 51 JAPAN INST METALS nickel foam Change of Young's Modulus with Increasing Applied Tensile Strain in Open Cell Nickel and Copper Foams 2433/152426 Zainuddin, M. Imran 2012/01/30 A new method for evaluating powder flowability, named vibration shear tube method has been developed. In this measurement system, the powder was discharged through a narrow gap between a vibrating tube edge and a flat bottom surface, where the particles experienced high shear forces to overcome the adhesion and friction forces. The vibration amplitude was increased during the measurement, and the mass of particles discharged was measured at constant time intervals. The amount of powder used for the measurement was about 10–40 g. The measurement time was 100–400 s. A series of experiments was carried out using alumina particles of 2–60 μm in mass median diameters. Flowability profiles, i.e. the relationships between the mass flow rate and the vibration acceleration were obtained experimentally. To characterize powder flowability, critical vibration acceleration and characteristic mass flow rate were proposed. The values of these factors were analyzed in detail and the performance of this measurement system was evaluated. 553 0032-5910 Powder Technology 548 217 Elsevier B.V.

In Fz-Si, {113} interstitial clusters were formed only near the beam incident surface after a long incubation period, and shrank on subsequent irradiation from the backside of the specimen. In Cz-Si and HT-Fz-Si, {113} interstitial clusters nucleated uniformly throughout the specimen without incubation, and began to shrink under prolonged irradiation at higher electron beam intensity. At lower beam intensity, however, the {113} interstitial cluster grew stably. These results demonstrate that the {113} interstitial cluster cannot grow without a continuous supply of impurities during electron irradiation. Detailed kinetics of {113} interstitial cluster growth and shrinkage in silicon, including the effects of impurities, are proposed. Then, experimental results are analyzed using rate equations based on these kinetics. 436 1478-6435 3 Philosophical Magazine 421 91 Taylor & Francis Czochralski grown silicon Effect of impurities on the growth of {113} interstitial clusters in silicon under electron irradiation 2433/76221 Ishiwari, Ryutaro 1968/03/30 387 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 379 45 Institute for Chemical Research, Kyoto University Comparison of Energy Losses of Protons and Deuterons of Exactly the Same Velocity 2433/76300 Takada, Toshio 1969/12/16 307 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 298 47 Institute for Chemical Research, Kyoto University Magnetic Properties of Several Iron Compounds Studied by the Mossbauer Effect (Commemoration Issue Dedicated to Professor Rempei Gotoh On the Occasion of his Retirement) 2433/85220 Ochiai, Shojiro 2009/09/29 A prediction method of the critical current-bending strain relation of the Bi2223 composite tape, which was bent at room temperature and cooled down to 77 K for measurement of critical current, was presented.

Labiosthenolepis andamanensis differs from L. laevis (McIntosh, 1885) by having oval, thin, flattened labial lobes and stylodes on the dorsal sides of segment 1, whereas in the latter species the labial lobes are thick, fleshy, lobulate, without stylodes on the dorsal sides of segment 1. The new species also differs from L. sibogae (Horst, 1917) by having dorsal tubercles on segment 3, which are absent in the latter species. 114 0389-6609 Publications of the Seto Marine Biological Laboratory.

Coherent x-ray diffraction patterns of a sample composed of 500-nm-thick Ni and Cu layers were measured at incident x-ray energies around the Ni K absorption edge. Non-center-symmetric diffraction patterns due to anomalous scattering phenomenon in the hard x-ray region were observed. Symmetricity of the diffraction pattern was quantitatively analyzed by numerically simulating the x-ray wave field behind the sample position using the Rytov approximation. By calculating the difference between the intensities of reconstructed images of different energies, an image of the Ni layers could be derived although it was not enough to identify precisely. This method is widely applicable to nondestructive analysis of nanometer-scale elemental distribution of materials buried within thick and high-Z samples. 1098-0121 9 PHYSICAL REVIEW B http://link.aps.org/doi/10.1103/PhysRevB.78.092105 78 American Physical Society Element-specific hard x-ray diffraction microscopy 2433/76586 Ito, Setsuro 1975/03/31 651 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 641 52 Institute for Chemical Research, Kyoto University Microstructure and Properties of Fused-Cast NaNbO₃-BaTiO₃ Ceramics 2433/68766 Shiki, Tsunemasa 1960/10/30 308 3 Memoirs of the College of Science, University of Kyoto.

In this paper, we report on the stable transmission of a transgene and its expression profile of the F4 generation in the transgenic medaka (Oryzias latipes). We established four transgenic strains, which contained a green fluorescent protein (GFP) gene controlled by a medaka P-actin promoter, using a particle gun. One more transgenic strain was also generated by microinjection for comparison. In all five strains, the founder was discovered to be mosaic for the transgene. However, from the F1 to F4 generations, transgenes and their expression profiles were stably inherited in the Mendelian manner. The expression profile was common among the five strains regardless of the method for gene transfer: GFP fluorescence became detectable at an early neurula stage. In this stage, the fluorescence was observed ubiquitously in most tissues. As somite developed, GFP fluorescence became intense only in the skeletal muscle and lens but it decreased in other tissues. In adult fish, an intense fluorescence was restricted in the skeletal muscle and lens, while a considerably weak fluorescence was observed in the brain, gill, heart, kidney, spleen, and ovary. From these results, it was concluded that the transgene and its expression profile were stably transmitted to offspring, and thus the particle gun is an effective method for transgenesis in spite of its easiness. 875 0289-0003 7 Zoological Science 869 20 Zoological Society of Japan medaka A transgene and its expression profile are stably transmitted to offspring in transgenic medaka generated by the particle gun method 2433/57210 Kawamura, Toshiyuki 2002/11/29 We established three transgenic medaka fish lines overexpressing the medaka estrogen receptor under the constitutive medaka beta-actin promoter. The transgenic embryos became hypersensitive to estrogens (17beta-estradiol and 17alpha-ethinylestradiol), and failed to develop yolk veins while blood clots formed in the blood island within 3 days after exposure to the estrogens. The embryos developed normally if exposed to estrogen after an early neurula stage, suggesting that the sensitive stage is before neurulation. The developmental defects were recovered by incubation with an anti-estrogen, tamoxifen. These results indicate that activation of estrogen receptor caused the estrogen-induced, developmental defects. Our results show that the transgenic embryos can be used to assay the blood clotting activity of estrogenic compounds in vivo. 1361 0289-0003 12 Zoological Science 1355 19 Zoological Society of Japan transgenic medaka fish Estrogen inhibits development of yolk veins and causes blood clotting in transgenic medaka fish overexpressing estrogen receptor 2433/76616 Oberlin, A. 1975/09/25 89 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 81 53 Institute for Chemical Research, Kyoto University Application of High Resolution Electron-Microscopy to the Study of Carbonaceous Materials (Commemoration Issue Dedicated to Professor Eiji Suito on the Occasion of his Retirement) 2433/77273 Kurata, Hiroki 1989/03/15 579 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 572 66 Institute for Chemical Research, Kyoto University Near Edge Structure in Electron Energy Loss Spectra of Chromium Trioxide Intercalalted into Graphite and Some Chromium Oxides (Commemoration Issue Dedicated to Professor Natsu Uyeda, on the Occasion of His Retirment) 2433/77274 Ueda, Uasukiyo 1989/03/15 571 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 562 66 Institute for Chemical Research, Kyoto University Structure of Octacyanocopperphthalocyanine Film Prepared by Chemical Vapor Deposition (Commemoration Issue Dedicated to Professor Natsu Uyeda, on the Occasion of His Retirment) 2433/77321 Itoh, Takahiro 1990/03/30 62 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 53 68 Institute for Chemical Research, Kyoto University Preparation and Monolayer Films of Cellobiose Alkyl Esters 2433/108563 Iseto, Tohru 2008/10/30 A new solitary entoproct, Loxosomella plakorticola sp. nov., was found on a sponge, Plakortis sp., on a coral reef slope on the western coast of Okinawa Island, Ryukyu Archipelago, Japan. This species has a medium-sized body (up to about 1.2 mm), slender proportion (the stalk is 0.83–1.76 times longer than the calyx), a slug-like foot with a foot gland and foot groove, and 14 to 18 tentacles. Small black pigment granules are visible only in the living stage in the calyx, stalk, and buds. This is the first report of a commensal loxosomatid from the Ryukyu Archipelago and the second species inhabiting sponges reported from Japan. Detailed morphological observations indicate that this species attaches to sponges by narrowing the foot groove; the sponge surface is pinched in the deepest part of the groove, which is free of the cuticle layer but covered by microvilli of epidermal cells. The accessory cells lining the foot groove have long been believed to be gland cells, but they are not gland cells in ultrastructure, at least in this species. 1178 0289-0003 11 Zoological Science 1171 25 Zoological Society of Japan A New Sponge-Inhabiting Loxosomella (Entoprocta: Loxosomatidae) from Okinawa Island, Japan, with Special Focus on Foot Structure 2433/108609 Ogasawara, Michio 2001/02/27 Recent progress in multiple and automated-sequencing technology allows large-scale random cDNA sequencing, the so-called EST project, in various fields. In addition to the EST collection, the cDNA project requires analysis of spatiotemporal patterns of gene expression of a large number of clones by whole-mount in situ hybridization (WISH). To facilitate the multiple WISH procedures, we developed a protocol for rapid and uniform synthesis of multiple probes and multi-well based WISH processing. A DIG-labeled RNA probe for WISH was synthesized from a PCR-amplified template which contained an RNA promoter. All reactions of PCR and subsequent RNA synthesis were performed in a single tube by sequential addition of the reagents without phenol extraction or ethanol precipitation steps. An RNA probe was purified and condensed by a centrifugal ultrafilter to achieve high and stable purification efficiency. WISH of 96 samples were performed simultaneously in a 96-well plate attached to silent screen filters that were connected with a vacuum exhausting system. These processes eliminated the labor-intensive steps of WISH and provided opportunities to search for novel genes. 193 0289-0003 2 Zoological Science 187 18 Zoological Society of Japan A Large-Scale Whole-Mount in situ Hybridization System: Rapid One-Tube Preparation of DIG-Labeled RNA Probes and High Throughput Hybridization using 96-Well Silent Screen Plates 2433/109868 Kim, Byungsoo 2009/04/29 Extraction and deposition of single atoms using an atomic force microscope tip is a promising technique for building nanostructures. Previous theoretical models for this technique, based on adiabatic atom motion in either classical or quantum mechanics settings, encountered an apparent difficulty in explaining atom extraction and deposition for the same experimental conditions. We resolve that difficulty by showing that both extraction and deposition of atoms can be formulated in terms of pure classical mechanics as a resonance effect, arising from a combination of interatomic forces and vibrations of individual atoms. 0031-9007 21 PHYSICAL REVIEW LETTERS http://link.aps.org/doi/10.1103/PhysRevLett.102.215502 102 American Physical Society Manipulation of Single Atoms by Atomic Force Microscopy as a Resonance Effect 2433/109815 Kanda, Kensuke 2009/05/30 Piezoelectric Pb(Zr, Ti)O3 (PZT) thin films were directly deposited on cantilever-shaped titanium substrates and evaluated for their piezoelectric properties and actuator performance. Because of the small difference in the thermal expansion coefficient between the PZT and the substrate, and the mitigation of the residual stress, large piezoelectric properties could be obtained for PZT/Ti unimorph actuators. X-ray diffraction measurements clearly revealed that the PZT thin films have a polycrystalline perovskite structure with a random orientation. Observations using a scanning electron microscope (SEM) demonstrated that PZT films, which were 3.8 mum thick, were densely deposited on Pt-coated Ti substrate without pores or cracks. The polarization-electric field (P- E) hysteresis of the PZT film clearly indicates ferroelectricity. The piezoelectric properties of the PZT films were evaluated from the tip displacement of PZT/Ti unimorph cantilevers. Simplified transverse piezoelectric coefficients (e31 * = d31/s11 E, where d31 and s11 E are piezoelectric coefficient and elastic compliance, respectively) were measured, which ranged from -3.6 to 4.3 C/m2 - about three times larger than those of the PZT thin films deposited on stainless-steel substrates. Measurement of resonant frequencies of the cantilevers shows a clear dependence on the cantilever length, which obeys the theoretical equation. This indicates that these cantilevers can be reliably applied as sensors and actuators in a resonance mode. 615 1057-7157 3 JOURNAL OF MICROELECTROMECHANICAL SYSTEMS 610 18 IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Microactuators Simple Fabrication of Metal-Based Piezoelectric MEMS by Direct Deposition of Pb(Zr, Ti)O-3 Thin Films on Titanium Substrates 2433/126667 Ito, Kazuhiro 2009/03/30 Smooth GaN layers were successfully grown on metallic TiN buffer layers by metalorganic chemical vapor deposition (MOCVD). One important factor in controlling GaN layer smoothness was the TiN layer thickness. We investigated systematically the effects of this thickness, and found an optimal thickness of 5 nm, at which the smallest average grain size (20 nm) and smoothest surface were obtained. The TiN layers increased surface coverage with GaN hexagons at an early stage of GaN growth, indicating that enhancing the GaN nucleation is essential for smooth GaN layer growth, and small grain size and smooth surface are needed to enhance GaN nucleation. Further reduction in TiN layer thickness to 2 nm decreased the surface coverage with GaN hexagons, and a high density of grooves and holes were observed in the surface of the 2-μm-thick GaN layers. Defect structures in the GaN layers grown on the TiN layers were remarkably changed on reduction of TiN layer thickness from 5 nm to 2 nm. GaN growth was found to be sensitive to the TiN layer thickness between 2 nm and 5 nm. 517 0361-5235 4 Journal of Electronic Materials 511 38 Springer Epitaxial growth of GaN Effects of TiN Buffer Layer Thickness on GaN Growth 2433/131802 Tokudome, Yasuaki 2010/12/15 The structure formation process of hierarchically porous alumina gels has been investigated by in situ small angle X-ray scattering (SAXS). The measurement was performed on the sol-gel solution containing aluminum chloride hexahydrate (AlCl(3)·6H(2)O), poly(ethylene oxide) (PEO), and propylene oxide (PO). The temporal divergence of scattering intensity in the low q regime was observed in the early stage of reaction, indicating that the occurrence of spinodal-decomposition-type phase separation. Detailed analysis of the SAXS profiles revealed that phase separation occurs between weakly branched polymerizing aluminum hydroxide (AH) and PEO. Further progress of the condensation reaction forms phase-separated two phases, that is, AH-rich phase and PEO-rich phase with the micrometer-range heterogeneity. The growth and aggregation of primary particles occurs in the phase-separated AH-rich domain, and therefore, the addition of PEO influences on the structure in nanometer regime as well as micrometer regime. The moderate stability of oligomeric species allows homogeneous condensation reaction parallel to phase separation and successful formation of hierarchically porous alumina gel. 308 0021-9797 2 Journal of colloid and interface science 303 352 Elsevier Inc.

The particles were produced by rapid expansion of liquid carbon dioxide through a nozzle, based on the Joule–Thomson effect. Their size distribution was measured by a laser diffraction method. The experimental results showed that the primary dry ice particles ejected from the nozzle were about 1 μm in mass median diameter. However, they grew initially in the jet flow and then became smaller due to sublimation. As a result, a bimodal size distribution was formed at increased distances from the nozzle outlet. The presence of a thermally insulated tube at the outlet of the expansion nozzle enhanced the agglomeration of the particles, whereby agglomerates of about 100 μm in mass median diameter were recorded. The agglomeration process is considered to take place by the simultaneous processes of particle deposition and reentrainment; i.e. agglomerated particles are reentrained from the layer of dry ice particles deposited on the tube walls. The agglomerate size decreased with increasing flow velocity, due to the greater detachment force applied to the deposition layer. Therefore, the flow velocity was found to be an important parameter influencing the agglomeration of dry ice particles. 9 0021-8502 Journal of Aerosol Science 1 48 Elsevier Ltd.

Observation of crystal defects in organic thin films has previously been performed at rather low resolution by conventional transmission electron microscopy based on phase-contrast imaging. Herein, we apply for the first time annular dark-field imaging to the direct observation of grain boundaries in copper hexachlorophthalocyanine thin films at the atomic resolution level by using an aberration-corrected scanning transmission electron microscope combined with electron energy-loss spectroscopy. By using a low-dose technique and an optimized detection angle, we were able to visualize the contrast of light element (C and N) together with the heavier elements (Cl and Cu) within the molecular column. We were also able to identify unexpected molecular orientations in the grain boundaries along the {110} crystallographic planes giving rise to stacking faults. 原子分解能で有機結晶薄膜中の欠陥構造観察に成功－有機デバイス材料の構造評価へ向けた新展開－. 京都大学プレスリリース. 2012-02-08. 2045-2322 Scientific Reports http://www.nature.com/srep/2012/120207/srep00252/full/srep00252.html 2 Nature Publishing Group Electronic materials and devices Direct observation of crystal defects in an organic molecular crystals of copper hexachlorophthalocyanine by STEM-EELS 2433/160643 Kaisei, Kiyohiro 2012/03/30 We have studied a local deposition method based on dynamic-mode AFM using a hollow tip with an aperture. In this method, liquid droplets are deposited onto a conductive substrate through the aperture by applying an electric voltage pulse and are imaged using the same AFM tip immediately after the deposition. In this study, we applied this method to local deposition of a glycerol solution, which can be utilized in the printed electronics and the biosensor fabrication technology. The solution in the hollow was covered with a hydrophobic ionic liquid with an extremely low vapor pressure to prevent the evaporation of the solution because the quick evaporation heavily affected the dynamic-mode AFM operation. We succeeded in the stable deposition of an array of ultrasmall droplets, which contained an added salt and possible involatile residues in the glycerol solution. 0021-8979 7 JOURNAL OF APPLIED PHYSICS http://link.aip.org/link/?jap/111/074319 111 American Institute of Physics atomic force microscopy Fabrication of glycerol liquid droplet array by nano-inkjet printing method 2433/163421 Kishimoto, Masashi 2010/10/30 Three-dimensional numerical simulation of SOFC anode polarization is conducted with a structure obtained by a focused ion beam and scanning electron microscope (FIB-SEM).

The crystal quality of the films is strongly dependent on preparation conditions, particularly substrate temperature and laser energy density, as well as Mn concentration. In the 7 cation% Mn-doped film grown under the optimized conditions, the full width at half maximum in the x-ray diffraction rocking curve for the (400) plane is 117 arcsec and the root-mean-square roughness of the surface is approximately 0.4 nm. These values are comparable to those of the spinel substrate.

Whether these two types of migration operate by similar cellular mechanisms remains unclear. We examined neuronal migration in mice deficient in mDia1 (also known as Diap1) and mDia3 (also known as Diap2), which encode the Rho-regulated actin nucleators mammalian diaphanous homolog 1 (mDia1) and mDia3. mDia deficiency impaired tangential migration of cortical and olfactory inhibitory interneurons, whereas radial migration and consequent layer formation of cortical excitatory neurons were unaffected. mDia-deficient neuroblasts exhibited reduced separation of the centrosome from the nucleus and retarded nuclear translocation. Concomitantly, anterograde F-actin movement and F-actin condensation at the rear, which occur during centrosomal and nuclear movement of wild-type cells, respectively, were impaired in mDia-deficient neuroblasts. Blockade of Rho-associated protein kinase (ROCK), which regulates myosin II, also impaired nuclear translocation. These results suggest that Rho signaling via mDia and ROCK critically regulates nuclear translocation through F-actin dynamics in tangential migration, whereas this mechanism is dispensable in radial migration. 神経細胞の配置メカニズムを解明－抑制性神経前駆細胞に特有の移動の機構が明らかに. 京都大学プレスリリース. 2012-1-16. 1546-1726 Nature neuroscience http://www.nature.com/neuro/journal/vaop/ncurrent/abs/nn.3020.html Nature Publishing Group A role for mDia, a Rho-regulated actin nucleator, in tangential migration of interneuron precursors. 2433/73214 Takahashi, Rieko 2007/09/25 Kyoto University author タンガニイカ湖産鱗食魚における食性の特化と形態の多様化 Feeding specialization and morphological diversification in scale eating cichlids from Lake Tanganyika 2433/156163 Matsumoto, Yusuke 2012/05/17 Bornaviruses are nonsegmented negative-strand RNA viruses that establish a persistent infection in the nucleus and occasionally integrate a DNA genome copy into the host chromosomal DNA. However, how these viruses achieve intranuclear infection remains unclear. We show that Borna disease virus (BDV), a mammalian bornavirus, closely associates with the cellular chromosome to ensure intranuclear infection. BDV generates viral factories within the nucleus using host chromatin as a scaffold. In addition, the viral ribonucleoprotein (RNP) interacts directly with the host chromosome throughout the cell cycle, using core histones as a docking platform. HMGB1, a host chromatin-remodeling DNA architectural protein, is required to stabilize RNP on chromosomes and for efficient BDV RNA transcription in the nucleus. During metaphase, the association of RNP with mitotic chromosomes allows the viral RNA to segregate into daughter cells and ensure persistent infection. Thus, bornaviruses likely evolved a chromosome-dependent life cycle to achieve stable intranuclear infection. 503 1931-3128 5 Cell host & microbe 492 11 Elsevier Inc.

However, the spatial organization of local excitatory connections to corticothalamic neurons is only partially understood. In the present study, we first developed an adenovirus vector expressing somatodendritic membrane-targeted green fluorescent protein. After injection of the adenovirus vector into the ventrobasal thalamic complex, a band of layer (L) 6 corticothalamic neurons in the rat barrel cortex were retrogradely labeled. In addition to their cell bodies, fine dendritic spines of corticothalamic neurons were well visualized without the labeling of their axon collaterals or thalamocortical axons. In cortical slices containing retrogradely labeled L6 corticothalamic neurons, we intracellularly stained single pyramidal/spiny neurons of L2-6. We examined the spatial distribution of contact sites between the local axon collaterals of each pyramidal neuron and the dendrites of corticothalamic neurons. We found that corticothalamic neurons received strong and focused connections from L4 neurons just above them, and that the most numerous nearby and distant sources of local excitatory connections to corticothalamic neurons were corticothalamic neurons themselves and L6 putative corticocortical neurons, respectively. These results suggest that L4 neurons may serve as an important source of local excitatory inputs in shaping the cortical modulation of thalamic activity. 18236 1529-2401 50 The Journal of neuroscience : the official journal of the Society for Neuroscience 18223 http://www.jneurosci.org/content/31/50/18223 31 Society for Neuroscience Local connections of excitatory neurons to corticothalamic neurons in the rat barrel cortex. 2433/157598 Wu, Nan 2012/03/26 Kyoto University Femtosecond laser フェムト秒レーザー照射による光誘導ナノ構造材料の研究 Studies on Photo-initiation of Nanostructure Materials by Femtosecond Laser Irradiation 2433/148309 藤沢, 浩訓 2004/01/23 京都大学 MOCVD法により作製した強誘電体Pb(Zr,Ti)O3薄膜及びナノ構造の物性に関する研究 2433/166084 Umeshima, Hiroki 2012/09/08 The cerebellar granule cell is a unique neuron which undergoes tangential migration along axonal tracts and radial migration along glial fibers sequentially during postnatal development. Little is known about molecular bases of the differential kinetics of tangential and radial migration. Here we developed a time-lapse imaging assay for tangential migration of cerebellar granule cells, and investigated comparative contributions of cyclin-dependent kinase 5 (CDK5), a key regulator of neuronal migration, in tangential and radial migration of granule cells in vivo and in organotypic cultures. Overexpression of a dominant-negative form of CDK5 severely disrupted cell morphology and somal movement during radial migration, while it only moderately affected tangential migration. Dominant-negative inhibition of CDK5 induced formation of ectopic radial processes in granule cells in vivo which aberrantly elongated into the white matter in the cerebellum. Live imaging of granule cell migration in cerebellar slices revealed that CDK5 regulates not only nuclear migration but also centrosome movement during radial migration. These findings suggest a mode-specific function of CDK5 in neuronal migration. 72 1044-7431 Molecular and cellular neurosciences 62 52 Elsevier Inc.

In-situ observation of the deformation and failure behavior was conducted with a digital microscope. Stress-strain curves were measured, in which a non-contact extensometer was employed to detect the strain of the samples accurately. Electric resistance was measured to monitor the damage evolution. Finite element stress analysis was conducted to calculate the morphological change of cells with applied strain and the stress distribution in cells. It was revealed that the deformation and failure progressed through the following four stages; stage I characterized by the elastic deformation, stage II by plastic deformation, stage III by the co-occurrence of plastic deformation and cumulative failure of struts and stage IV by the chain reaction of strut failure nearly in a limited cross-section, respectively. Also it was found that the distribution of failure strain of struts in stage III, measured from the serrations in the stress-strain curve, could be described by the Weibull distribution, with which the transition from stage II to III was identified. Also, the result of the statistical analysis suggested that the average failure strain of the struts in the foam is much higher than the strain at ultimate stress of the foam. 706 1345-9678 4 MATERIALS TRANSACTIONS 699 51 JAPAN INST METALS nickel foam Tensile Deformation and Failure Behavior of Open Cell Nickel and Copper Foams 2433/152507 Okeyo, Kennedy Omondi 2011/08/30 Actin polymerization-driven protrusion of the lamellipodia is a requisite initial step during actin-based cell migration, and is closely associated with attachment to the substrate. Although tremendous progress has been made in recent years toward elucidating the molecular details of focal adhesions, our understanding of the basic coordination of protrusion and adhesion, and how the two fundamental processes relate to actomyosin contractility is still inadequate. Therefore, to highlight the effect of cell–substrate interactions on the protrusive dynamics of the lamellipodia and to correlate protrusion with actomyosin activities, this study investigated the migration of fish epidermal keratocytes on fibronectin micropatterns intercalated with adhesion-suppressed gaps of varying widths. We show that insufficient adhesion associated with the gaps could limit lamellipodial protrusion such that the percentage of migrating cells decreases with an increase in gap width, and protrusion across the gaps is accompanied by ruffling. Moreover, our results suggest that up-regulating actomyosin contractility enhances the mechanical integrity of the actin cytoskeleton, leading to an increase in the width of the lamellipodia, and consequently, an increase in the percentage of cells migrating across the gaps. Thus, we demonstrate that the protrusion dynamics at the leading edge of migrating cells are functionally involved in the global mechanical regulation of actin cytoskeletal components that enable cell migration. 398 1865-5025 3 Cellular and Molecular Bioengineering 389 4 Springer Verlag Cell migration Effect of Actomyosin Contractility on Lamellipodial Protrusion Dynamics on a Micropatterned Substrate 2433/154572 Takahashi, Tetsumi 2012/02/28 The dwarf morph of the Lake Tanganyika cichlid Telmatochromis temporalis uses empty snail shells as shelters and breeding sites in shell beds, in which many empty shells exist. Here, we assessed selection forces regulating body size in this fish. Field observations showed that large males tended to have a greater number of females in their territories, suggesting that sexual selection favours large males. Nonetheless, a transplant experiment suggested that male body size was limited by the ability to hide in empty shells from large piscivorous fish. In females, the number of ovarian eggs increased with body size, suggesting that fecundity selection favours large females. However, females are smaller than males. Females spawned eggs close to the apices inside the shells. The small space there would decrease the risk of egg predation by egg predators, and small body size of females may be a result of adaptation to spawn eggs in the small, safe spaces. This study provides support for the idea that male and female body sizes have been limited by different ecological pressures (predation on adult fish in males, predation on eggs in females), which has not been reported previously in any animal. 44 0018-8158 1 Hydrobiologia 35 684 Springer Science+Business Media B.V.

AUAb was present in serum samples from approximately half of the double-knockout (DKO) mice, as detected by immunofluorescence and immunoblots for urothelial proteins including uroplakin IIIa. The AUAb-positive DKO mice showed degeneration of urothelial plaque and umbrella cells, along with infiltration of inflammatory cells in the suburothelial layer. TNFα and IL-1β were upregulated in the bladder and the urine of AUAb-positive DKO mice. Voiding behavior of mice was analyzed by the Voided Stain on Paper method. 10-week-old and older AUAb-positive DKO mice voided significantly less urine per void than did wild type (WT) mice. Furthermore, administration of the AUAb-containing serum to WT mice significantly reduced their urine volume per void.

Tension wood was composed of well developed gelatinous fibers and was characteristic in its low lignin and pentosan contents as well as its high ash, alpha-cellulose and uronic acid contents. Carbohydrate portion of tension wood has been found to be peculiar in that tension wood contains the highest amount of galactose in contrast to the lowest amount of mannose among three types of wood. Each wood was further subjected to sequential fractional extractions. The peculiarity of the chemical composition of the tension wood reflected the differences in the carbohydrate compositions of the extracted hemicelluloses. In analysing the molecular weight distribution of the extracted hemicelluloses by gel nitration on Sepharose 4B, it has been found that all components included in the gel matrices have quite similar molecular weights in spite of the differences in the carbohydrate compositions. These results may give a clue in ellucidation of the distribution and function of hemicelluloses in wood. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 21 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 8 68 Wood Research Institute, Kyoto University Studies on Hemicelluloses in Tension Wood : I.

The latter species is also reported from the Gulf of Thailand and is a new record from Thai and Japanese waters. The position of the ceratophore of the median and lateral antennae, the occurrence of stylodes on the anterior and posterior lower lobes of segment 2- 5, and the number of pairs of labial ctenidia are the main characters used for distinguishing these two species from other members of the genus. 34 0389-6609 Publications of the Seto Marine Biological Laboratory.

A humidity control system was installed on a tensile-mode fatigue tester equipped with an electrostatic force grip. A specimen and a griping device were inserted into a small chamber and the humidity was controlled by air flow from a temperature and humidity chamber. The humidity stability was within ±2%RH for humidities in the range 25–90%RH for eight hours of testing. Fatigue tests were performed on single-crystal silicon (SCS) specimens in constant humidity environments and laboratory air for up to 106 cycles. The gauge length, width, and thickness of the SCS specimens were 100 or 500 μm, 13.0 μm, and 3.3 μm, respectively. The average tensile strength was 3.68 GPa in laboratory air; this value decreased in high humidity environments. Fatigue failure was observed during cyclic loading at stresses lower than the average strength. A reduction in the fatigue strength was observed at high relative humidities. Different fracture origins and fracture behaviors were observed in tensile tests and fatigue tests, which indicates that the water vapor in air affects the fatigue properties of SCS specimens. 516 0014-4851 4 Experimental Mechanics 509 50 Springer Microelectromechanical systems Tensile and Tensile-Mode Fatigue Testing of Microscale Specimens in Constant Humidity Environment 2433/163418 Balela, Mary Donnabelle L. 2010/10/30 Metallic Co nanowires with a mean diameter of about 190 nm and lengths up to 160 µm are prepared by electroless deposition (solution reduction) in propylene glycol at room temperature under external magnetic field. Co deposition behavior in propylene glycol is investigated by in situ monitoring of mixed potentials in conjunction with linear sweep voltammetry and the oxidation-reduction potential of the Co(II)/Co redox pair is determined to be about −0.54 V vs Ag/AgCl. When the mixed potential drops below the oxidation-reduction potential of the Co(II)/Co redox pair, small Co nanoparticles are generated in the solution and are magnetized in the presence of external magnetic field. Strong attractive dipolar interactions are induced along the magnetic field direction, which results in the assembly of Co nanoparticles to nanowires. The Co nanowires exhibit ferromagnetic properties at room temperature, with an enhanced coercivity of about 700 Oe possibly due to shape anisotropy.

Under appropriate conditions, a nanoporous surface layer with a thickness of 150–250 nm was generated. The extended immersion of the sample in the electrolyte (HNO3) increased the ligament size of the nanoporous architecture up to 41 nm. Cross-sectional observations suggested that the nanoporous surface layer can be seamlessly bonded to the bulk substrate Au. True surface area, which was measured by an electrochemical method, decreased as ligament size increased by the extended immersion. The relationship among surface area, ligament size and volume shrinkage was investigated. 2343 0167-577X 21 Materials Letters 2341 64 Elsevier B.V.

Noninvasive observation of donor cell homing shortly after transplantation is potentially valuable for improving therapeutic outcomes of BMT by diagnosing the early stages of these diseases. METHODOLOGY/PRINCIPAL FINDINGS: Freshly harvested near-infrared fluorescence-labeled cells were noninvasively observed for 24 h after BMT using a photon counting device to track their homing process. In a congenic BMT model, the homing of Alexa Fluor 750-labeled donor cells in the tibia was detected less than 1 h after BMT. In addition, subsequent cell distribution in an intraBM BMT model was successfully monitored for the first time using this method. In the allogeneic BMT model, T-cell depletion decreased the near-infrared fluorescence (NIRF) signals of the reticuloendothelial system. CONCLUSIONS/SIGNIFICANCE: This approach in several murine BMT models revealed that the transplanted cells homed within 24 h after transplantation. NIRF labeling is useful for tracking transplanted cells in the initial phase after BMT, and this approach can contribute to in vivo studies aimed at improving the therapeutic outcomes of BMT. 1932-6203 6 PloS one 5 Public Library of Science Noninvasive tracking of donor cell homing by near-infrared fluorescence imaging shortly after bone marrow transplantation 2433/49857 Magome, N 2002/03/30 1063-651X 4 PHYSICAL REVIEW E http://link.aps.org/abstract/PRE/v65/p045202 65 AMERICAN PHYSICAL SOC Rhythmic bursting in a cluster of microbeads driven by a continuous-wave laser beam 2433/145976 Watanabe, Hitomi 2011/08/01 Mammalian sperm undergo several maturation steps after leaving the testis to become competent for fertilization. Important changes occur in sperm within the female reproductive tract, although the molecular mechanisms underlying these processes remain unclear. To investigate sperm membrane remodeling upon sperm maturation, we developed transgenic mouse lines carrying glycosylphosphatidylinositol (GPI)-anchored enhanced green fluorescent protein (EGFP-GPI) and traced the fate of this fluorescent protein during the fertility-acquiring process in sperm in vitro and in vivo. When the GFP-labeled sperm were treated with compounds for promoting the acrosome reaction, EGFP-GPI was released from the sperm surface crosslinked with characteristic relocation of a lipid raft marker ganglioside GM1. Sperm ejaculated into the uterus strongly expressed EGFP-GPI in the head region, whereas a part of the oviductal sperm lost fluorescence in a manner that was dependent on the presence of angiotensin-converting enzyme (ACE). Moreover, sperm on the zona pellucida of eggs in the oviduct were all found to have low levels of GFP. These results suggest that sperm undergoing GPI-anchored protein release associated with reorganization of lipid rafts and the acrosome reaction acquire fertilization potential. 2581 0021-9533 15 Journal of cell science 2573 124 Company of Biologists Sperm Mouse sperm undergo GPI-anchored protein release associated with lipid raft reorganization and acrosome reaction to acquire fertility. 2433/149205 Nakagawa, Takayuki 2011/08/30 Repeated intermittent exposure to psychostimulants and morphine leads to progressive augmentation of its locomotor activating effects in rodents. Accumulating evidence suggests the critical involvement of the mesocorticolimbic dopaminergic neurons, which project from the ventral tegmental area to the nucleus accumbens and the medial prefrontal cortex, in the behavioral sensitization. Here, we examined the acute and chronic effects of psychostimulants and morphine on dopamine release in a reconstructed mesocorticolimbic system comprised of a rat triple organotypic slice co-culture of the ventral tegmental area, nucleus accumbens and medial prefrontal cortex regions. Tyrosine hydroxylase-positive cell bodies were localized in the ventral tegmental area, and their neurites projected to the nucleus accumbens and medial prefrontal cortex regions. Acute treatment with methamphetamine (0.1-1000 µM), cocaine (0.1-300 µM) or morphine (0.1-100 µM) for 30 min increased extracellular dopamine levels in a concentration-dependent manner, while 3,4-methylenedioxyamphetamine (0.1-1000 µM) had little effect. Following repeated exposure to methamphetamine (10 µM) for 30 min every day for 6 days, the dopamine release gradually increased during the 30-min treatment. The augmentation of dopamine release was maintained even after the withdrawal of methamphetamine for 7 days. Similar augmentation was observed by repeated exposure to cocaine (1-300 µM) or morphine (10 and 100 µM). Furthermore, methamphetamine-induced augmentation of dopamine release was prevented by an NMDA receptor antagonist, MK-801 (10 µM), and was not observed in double slice co-cultures that excluded the medial prefrontal cortex slice. These results suggest that repeated psychostimulant- or morphine-induced augmentation of dopamine release, i.e. dopaminergic sensitization, was reproduced in a rat triple organotypic slice co-cultures. In addition, the slice co-culture system revealed that the NMDA receptors and the medial prefrontal cortex play an essential role in the dopaminergic sensitization. This in vitro sensitization model provides a unique approach for studying mechanisms underlying behavioral sensitization to drugs of abuse. 1932-6203 9 PloS one 6 Public Library of Science Repeated exposure to methamphetamine, cocaine or morphine induces augmentation of dopamine release in rat mesocorticolimbic slice co-cultures. 2433/152876 Shinto, Hiroyuki 2012/03/01 It is of fundamental importance to understand the mechanism of adhesion between a mammalian cell and a material surface. In the present study, we have used atomic force microscopy (AFM) to measure the interaction forces between the murine melanoma cells and the single polystyrene microspheres of different surface chemistries in serum-free culture media: the unmodified hydrophobic polystyrene (bare/PS) and the carboxyl-modified polystyrene (COOH/PS). The cell-microsphere interaction forces have been also measured in the culture media containing the free Arg-Gly-Asp (RGD) peptides as an integrin inhibitor. In the absence of free RGD peptides, the adhesion force for COOH/PS was larger than that for bare/PS. The adhesion force for COOH/PS decreased with increasing the concentration of free RGD peptides added in the culture media and then became almost constant at the RGD concentrations larger than 0.5 mg/mL, whereas that for bare/PS remained very small regardless of the RGD concentration. In addition, the effects of the microsphere diameter and the contact time on the adhesion forces were investigated. On the basis of the AFM results, possible mechanism of cell-microsphere adhesion will be discussed. 121 1873-4367 Colloids and surfaces. B, Biointerfaces 114 91 Elsevier B.V.

Various functional groups and bioactive substances can be immobilized to the cell surface through covalent conjugation, hydrophobic interaction, or electrostatic interaction. In this review, we provide an overview of the methods and polymers employed in cell surface modification, including: (1) covalent conjugation utilizing amino groups of cell surface proteins, (2) hydrophobic interaction of amphiphilic polymers with a lipid bilayer membrane, and (3) electrostatic interactions between cationic polymers and a negatively charged cell surface. We also discuss their applications in studies on cell therapy, cell–cell interaction analysis, cell arrangement, and lineage determination of stem cells. 1091 1744-683X 6 Soft Matter 1081 6 Royal Society of Chemistry Cell surface modification with polymers for biomedical studies 2433/156410 KOBAYASHI, Chisato 2004/07/21 436 0452-9987 4 Contributions from the Biological Laboratory, Kyoto University 431 29 京都大学大学院人間・環境学研究科 A new species of Poropoea (Trichogrammatidae) oviposites by entering through the oviposition hole of attelabid beetle 2433/85224 Sulistyo, Joko 2009/01/30 Composites with characteristics of anisotropic thermal conductivity for thermal management in Solar Power Satellite (SPS), to discharge the heat that was generated when solar energy was not converted to electricity, were developed by alternating layers of laminated graphite and carbonized wood. The effects of the weight fraction of carbonized wood, particle size, interlayer interfaces, and environment temperature on the thermal conductivity and the ratio of thermal conductivity between horizontal and vertical directions (H/V ratio) to the plain surface of samples were discussed. The thermal conductivities of carbon–graphite (C/G) composites were measured using the laser flash method. Laminated C/G composites improved the anisotropic thermal conductivity. The highest H/V ratio of 10.17 was obtained at 10 wt% of carbonized wood. Particle size and interlayer interfaces were found to affect the anisotropic thermal conductivity. The thermal conductivity of C/G composites increased with increasing temperature from 25 °C to 150 °C. 744 0022-2461 3 Journal of Materials Science 734 44 Springer Anisotropic thermal conductivity of three-layer laminated carbon-graphite composites from carbonized wood 2433/88962 Taketomi, Shinya 2008/01/30 1169 0022-2461 3 Journal of Materials Science 1166 43 Springer Netherlands Atomistic simulation of the effects of hydrogen on the mobility of edge dislocation in alpha iron 2433/74422 1952/03/30 0023-6071 京都大学化学研究所報告 28 京都大学化学研究所 COVER, CONTENTS 表紙・編輯後記・化學研究所報告第28集目次 2433/75450 Takiyama, Kazuyoshi 1954/07/31 148 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 143 32 Institute for Chemical Research, Kyoto University An Electron Microscopic Study on the Suspensoid for the Nephelometry of Sulfate Ion 2433/75480 Kikuchi, Takehiko 1954/10/30 105 0023-6071 s Bulletin of the Institute for Chemical Research, Kyoto University 99 32 Institute for Chemical Research, Kyoto University Paper XI Studies on the Metabolism of Fission Products III.

However, thrombosis, inflammation, and restenosis are still major problems for the utility of cardiovascular prostheses such as vascular grafts and stents. Epigallocatechin-3-O-gallate (EGCG), a major polyphenolic constituent of green tea, has been shown to have anti-thrombotic, anti-inflammatory and anti-proliferative activities. It was hypothesized that controlled release of EGCG from biodegradable poly(lactide-co-ε-caprolactone, PLCL) stent coatings would suppress migration and invasion of vascular smooth muscle cells (VSMCs) as well as platelet-mediated thrombosis. EGCG-releasing PLCL (E-PLCL) was prepared by blending PLCL with 5% EGCG. The surface morphology, roughness and melting temperature of PLCL were not changed despite EGCG addition. EGCG did, however, EGCG appreciably increase the hydrophilicity of PLCL. EGCG was found to be uniformly dispersed throughout E-PLCL without direct chemical interactions with PLCL. E-PLCL displayed diffusion controlled release of EGCG release for periods up to 34 days. E-PLCL significantly suppressed the migration and invasion of VSMCs as well as the adhesion and activation of platelets. E-PLCL coatings were able to smooth the surface of bare stents with neither cracks nor webbings after balloon expansion. The structural integrity of coatings was sufficient to resist delamination or destruction during 90% dilatation. These results suggest that EGCG-releasing polymers can be effectively applied for fabricating an EGCG-eluting vascular stent to prevent in-stent restenosis and thrombosis. 893 0142-9612 7 Biomaterials 884 29 Elsevier Stent The behavior of vascular smooth muscle cells and platelets onto epigallocatechin gallate-releasing poly(l-lactide-co-ε-caprolactone) as stent-coating materials 2433/76383 Bando, Yoshichika 1972/01/31 348 0023-6071 5 Bulletin of the Institute for Chemical Research, Kyoto University 342 49 Institute for Chemical Research, Kyoto University Substitution of Manganese Ions for Iron Ions in Dicalcium Ferrite 2433/52556 Isshiki, Nobuhiko 1979/10/30 32 0300-1067 音声科学研究 = Studia phonologica 25 14 INSTITUTION FOR PHONETIC SCIENCES UNIVERSITY OF KYOTO Current Topics in Phonosurgery 2433/49174 Hase, Masahiko 2006/07/30 When a cell-sized water droplet, with a diameter of several tens of μm, is placed in oil containing phospholipids, a phospholipid monolayer is formed spontaneously on the droplet surface to produce a stable cell-sized micro-container. We report on the transportation of such ‘vesicle’ between an oil and a water phases across a lipid monolayer at the bulk water/oil interface by micromanipulation technique. The ‘vesicle’ can be returned onto the oil phase, and the transportation can be performed back and forth between the two-phases repeatedly. Such a vesicle-like, easily manipulable micro-container may afford a simple model of living intra-cellular environments. 444 0009-2614 4-6 Chemical Physics Letters 441 426 Elsevier Transport of a cell-sized phospholipid micro-container across water/oil interface 2433/52383 1968/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 19 0009-3378 1 京都大学結核胸部疾患研究所紀要 11 2 京都大学結核胸部疾患研究所 English abstracts 2433/53402 1973/09/14 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 36 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 32 55 Wood Research Institute, Kyoto University Abstracts 2433/52343 岡田, 慶夫 1971/01/30 Squamo-glandular junction in the esophago-gastric junction was observed by scanning and translucent electron microscope, and the following results were obtained : 1) The surface of the squamo-glandular junction was quite distinct under the scanning electron microscopy. 2) The squamous epithelial cell of the esophagus and the glandular epithelial cell of the stomach interdigitate with each other.

Both in cytological and histological specimen, specific fluorescence of LDH-H and LDH-M were seen in the cytoplasm of cancer cells, and in most cases no remarkable difference could be demonstrated between the distribution of H and M subunit. But in some cases specific fluorescence of M-subunit was stronger than that of H-subunit. The fluorescence of M-subunit was demonstrated as fine granules diffusely in the cytoplasm. On the other hand the fluorescence of H-subunit was rather localized and demonstrated as rather coarse granules. And this observation was discussed. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 18 0009-3378 1 京都大学結核胸部疾患研究所紀要 11 8 京都大学結核胸部疾患研究所 IMMUNOHISTOCHEMICAL STUDIES ON LACTATE DEHYDROGENASE SUBUNITS IN LUNG CANCER CELLS 2433/77037 Isoda, Seiji 1983/09/20 228 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 222 61 Institute for Chemical Research, Kyoto University Crystal Structure of Poly (2-chloro-p-xylylene) (Special Issue on Polymer Chemistry, XVIII) 2433/77119 Nakamura, Naotake 1985/11/25 191 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 186 63 Institute for Chemical Research, Kyoto University Studies of Thermal Expansion and Diffuse Scatterings in the Successive Phase Transitions of Cholesteryl 2, 2, 3, 3-Tetrafluoropropionate(CTFP) by X-ray Diffraction Method (Commemoration Issue Dedicated to Professor Naokazu Koizumi on the Occasion of his Retirement) 2433/77150 Miyamoto, Kei 1986/12/06 291 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 287 64 Institute for Chemical Research, Kyoto University Preparation of Al₂O₃ Ceramics by Low Pressure Injection Molding (Commemoration Issue Dedicated to Professor Toshio TAKADA On the Occasion of His Retirement) 2433/84955 2008/10/30 101 1342-0321 ICR annual report 98 15 Institute for Chemical Research, Kyoto University The 108th ICR Annual Symposium 2433/53273 BABA, Kei'ichi 1990/12/28 Immuno-gold electron microscopical observation indicated that the bark lectin of Sophora japonica is localized in the Golgi apparatus and the intravacuolar electron-dense materials, suggesting that the lectin is transported through the Golgi apparatus on the way from the ER to the vacuole.

It is possible that some of the lectin molecules or subunits may be transported through the Golgi apparatus and the others of them may be transported directly from ER to vacuole in the parenchyma cells of the bark of Sophora japonica. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 7 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 1 77 Wood Research Institute, Kyoto University bark (phloem) Electron Microscopical Studies on the Deposition Route of the Bark Lectin of Sophora japonica 2433/50206 Hiwatashi, K 2007/03/30 1070-6631 4 PHYSICS OF FLUIDS http://link.aip.org/link/?phf/19/048103 19 AMER INST PHYSICS Experimental observations of instabilities in rotating plane Couette flow 2433/51763 TAKAMATSU, Hideo 1954/05/30 Histochemical demonstration of glycogen synthesis was attempted. In these experiments, tissue blocks were incubated in a substrate solution. Fresh tissues were removed from starved rats. These tissues contained almost no stainable substances by Best's Carmine solution but after incubation the tissues of the same individuals showed many substances. Best's Carmine will stain only polysaccharides of high molecular weight but not those of lower molecular weight. On the other hand, periodic acid Schiff method reacts with polysaccharide of both high and low molecular weights. We proved the synthesis of polysaccharide of high molecular weight from fructose menophosphate. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 11 1 Acta tuberculosea Japonica 7 4 Tuberculosis Research Institute, Kyoto University Histochemical Demonstration of Glycogen Synthesis in vitro 2433/77591 Hoshino, Akitaka 1995/02/24 393 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 387 72 Institute for Chemical Research, Kyoto University STM, SEM and TEM Observations of Lead-phthalocyanine Vacuum-deposited on Graphite 2433/147159 Kawaguchi, Kosuke 2011/09/26 The yeast Candida boidinii capable of growth on methanol proliferates and survives on the leaves of Arabidopsis thaliana. The local methanol concentration at the phyllosphere of growing A. thaliana exhibited daily periodicity, and yeast cells responded by altering both the expression of methanol-inducible genes and peroxisome proliferation. Even under these dynamically changing environmental conditions, yeast cells proliferated 3 to 4 times in 11 days. Among the C1-metabolic enzymes, enzymes in the methanol assimilation pathway, but not formaldehyde dissimilation or anti-oxidizing enzymes, were necessary for yeast proliferation at the phyllosphere. Furthermore, both peroxisome assembly and pexophagy, a selective autophagy pathway that degrades peroxisomes, were necessary for phyllospheric proliferation. Thus, the present study sheds light on the life cycle and physiology of yeast in the natural environment at both the molecular and cellular levels. 微生物（C１酵母）は植物葉上に浸み出したアルコールを夜に飲む～細胞センサーの開発と植物葉上のメタノール変動～. 京都大学プレスリリース. 2011-09-27. 1932-6203 9 PLoS ONE e25257 6 PLoS Yeast Methylotrophy and Autophagy in a Methanol-Oscillating Environment on Growing Arabidopsis thaliana Leaves 2433/75927 Horio, Masao 1963/01/30 363 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 358 40 Institute for Chemical Research, Kyoto University Comparison between the Effect of Permanganate/Sodium Chloride and That of Permanganate/Water upon Wool 2433/76179 1967/02/25 450 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 443 44 Institute for Chemical Research, Kyoto University Conspectus (Special Issue on the Commemoration of the Fortieth Anniversary) 2433/77211 Kiyama, Masao 1988/03/15 191 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 187 65 Institute for Chemical Research, Kyoto University The Formation and Growth of a-Fe₂O₃ Particles by Transformation of γ-Fe₂O₃ in Alkaline Media 2433/77256 Sano, Yoh 1989/02/28 485 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 481 66 Institute for Chemical Research, Kyoto University Structure of Tobacco Mosaic Virus A-protein in Low Ion Concentration at Alkaline pH.

Sample collection was conducted from 18 sites, mostly carried out by wading and SCUBA diving during daytime and the observations were randomly conducted in all collection sites. The results showed that 72 species from 11 orders, 37 families and 52 genera were identified. Out of these, three species were the new records from Thai Waters, namely Placospongia melobesioides, Eurypon sp. “black” and Rhabderemia sp. “brown”. Most species were previously found in the Gulf of Thailand and the South China Sea. Species occurrence in various habitats was noted for some common sponges. 23 0037-2870 Publications of the Seto Marine Biological Laboratory 17 41 Seto Marine Biological Laboratory, Kyoto University Marine sponges Species Diversity of Marine Sponges along Chanthaburi and Trat Provinces, the Eastern Coast of the Gulf of Thailand 2433/166983 池田, 政晴 1935/02/25 171 167 天界 = The heavens 168 15 東亞天文協會 学術用語特に天文学用語に就て 學術用語特に天文學用語に就て 2433/169100 Araki, Sumiko 2009/04/20 真核生物で見られる階層的な折りたたみの基本構造としてヌクレオソーム(長さ50nmのDNAがコアヒストンと呼ばれる直径7nmのタンパクに巻きついた構造)が知られている。DNAの長さ、ねじれ、大域的な構造(環状等)がヌクレオソーム形成に与える影響は未だ十分に理解されていない。本研究ではDNAの両端がつながっている環状構造がヌクレオソーム形成に与える影響を明らかにするために、全長1マイクロメートルの線状・環状DNAを用いて再構成を行い、その効率とヌクレオソーム間相互作用の検討を行った。その結果、環状のDNAを用いた場合の方が環状構造に由来して再構成の効率が高くなることが明らかになった。 この論文は国立情報学研究所の電子図書館事業により電子化されました。 130 0727-2997 1 物性研究 129 92 物性研究刊行会 The hierarchical structure of chromatin : Nucleosomal array reconstitution with ring and linear DNA(Knots and soft-matter physics: Topology of polymers and related topics in physics, mathematics and biology) 2433/173163 Isojima, Toshinori 2013/02/27 Staining-type hypermelanosis, defined as blind-side melanosis occurring after completion of metamorphosis, reduces commercial value in hatchery-produced flatfishes. Detailed characterization was performed on the stained area of juvenile Japanese flounder Paralichthys olivaceus to physiologically understand this phenomenon. From 80 to 120 days after hatching, juveniles were reared in sandy and sandless tanks. By classifying the staining degree into 7 levels, about 2 times higher occurrence of middle-level staining was reconfirmed in sandless tank (about 80 %) than in sandy tank (about 40 %). In the stained area, we found 3 types of chromatophores (melanophore, xanthophore, and iridophore) and ctenoid scales, which would be typically observed on the normal ocular side. Detailed examination on the melanophores revealed further similarity between the stained area and the normal ocular side, in terms of the distribution at 2 layers (shallower and deeper than scale), and the densities in both layers (about 1000 cells/mm2 above scale and 200 cells/mm2 beneath scale). These results strongly suggest that the staining is a status change in the body surface conditions from the blind side to that on the ocular side, and not a simple darkening caused by disordered proliferation of melanophores on the blind side. 242 0919-9268 2 Fisheries Science 231 79 Springer Japan Coloration Formation process of staining-type hypermelanosis in Japanese flounder juveniles revealed by examination of chromatophores and scales 2433/173348 Shinto, Hiroyuki 2013/01/30 We have measured the interaction forces between a murine melanoma cell and a poly(L-lactic acid) (PLLA) microsphere coated with/without hydroxyapatite (HAp) nanoparticles (i.e., an HAp/PLLA or a bare PLLA microsphere) in a serum-free culture medium, using atomic force microscopy (AFM) with colloid probe technique, in order to investigate how the HAp-nanoparticle coating as well as interfacial serum proteins influence the cell-microsphere adhesion. The cell adhesion force of the HAp/PLLA microspheres was 1.4-fold stronger than that of the bare PLLA microspheres. When the microspheres were pretreated with a culture medium supplemented with 10% fetal bovine serum, the cell adhesion force of the HAp/PLLA microspheres was increased by a factor of 2.1; in contrast, no change was observed in the cell adhesion force of the bare PLLA microspheres before/after the pretreatment. Indeed, the cell adhesion force of the HAp/PLLA was 2.8-fold larger than that of the bare PLLA after the pretreatment. Additionally, we have investigated the effect of interfacial serum proteins on the zeta potentials of these microspheres. On the basis of the obtained results, possible mechanism of cell adhesion to the HAp/PLLA and bare PLLA microspheres in the presence/absence of the interfacial serum proteins is discussed. 15 0927-7765 Colloids and surfaces.

The functions of the nanocolumnar and the uniform sublayers are to control shape of the Ag nanorods and to tune optical path length inside the sandwich, respectively. Calculations based on a simple model by treating the NRAs as uniform effective media indicate that the antireflection condition is realized by changing the thickness of the dielectric layer and that the Ag nanorods absorb most of the incident light. The designed structures have been successfully fabricated by taking advantages of the dynamic oblique-angle deposition technique. Under the experimental antireflection condition, Raman scattering measured on the Ag NRA in the near infrared region exhibits significant enhancement. This indicates that the local electric field close to the Ag nanorods can be controlled by the interference of light in the nanostructured sandwiches.

Water molecules are arranged along the Cu row to form "ferroelectric" zigzag chains of trimer to hexamer. The trimer prefers the chain form to a cyclic one in spite of the reduced number of hydrogen bonds, highlighting the crucial role of the water-substrate interaction in the clustering of adsorbed water molecules. On the other hand, the cyclic form with maximal hydrogen bonds becomes more favorable for the tetramer, indicating the crossover from chain to cyclic configurations as the constituent number increases. 0021-9606 2 The Journal of chemical physics 134 American Institute of Physics adsorption Water clusters on Cu(110): Chain versus cyclic structures. 2433/129433 Shinmen, Tsubasa 2010/09/29 As it walks, the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) spins a trail of silk threads, that is followed by the predatory mite, Neoseiulus womersleyi Schicha (Acari: Phytoseiidae). Starved adult female N. womersleyi followed T. urticae trails laid down by five T. urticae females but did not follow a trail of one T. urticae female, suggesting that the amount of spun threads and their chemical components should correlate positively with the number of T. urticae individuals. To examine whether chemical components of T. urticae trails are responsible for the predatory mite's trail following, we collected separate T. urticae threads from the exuviae and eggs, and then washed the threads with methanol to separate chemical components from physical attributes of the threads. Female N. womersleyi did not follow T. urticae trails that had been washed with methanol but contained physical residues, but they did follow the direction to which the methanol extracts of the T. urticae trails was applied. These results suggest that the predatory mite follows chemical, not physical, attributes of T. urticae trails. 118 0168-8162 2 Experimental & applied acarology 111 52 Springer Science+Business Media B.V.

A 42-year-old man visited with the complaint of urethral discharge and urethral tumor on May 24, 1985. A small fingertip sized, elastic hard mass was present on the left side of the external urethral meatus. Cold cup biopsy of the urethral tumor was done. Histological examination of the tumor showed amorphous eosinophilic tissue staining. Green birefringence indicating amyloidosis by Congo red staining was observed under polarized light microscope. Since the patient's symptoms were minimal, no specific therapy was instituted. 105 0018-1994 1 泌尿器科紀要 101 33 泌尿器科紀要刊行会 Amyloidosis A case of localized amyloidosis of the urethra 限局性尿道アミロイドーシスの1例 2433/119194 狩野, 健一 1987/06/29 The possible mechanism of penile erection was discussed based on the findings obtained by the scanning electron microscope observations of the penile vascular casts in the dog. Polsters protruding into the lumen of the distal helicine arteries regulate blood flow into the cavernous spaces. The drainage veins from the corpus cavernosum penis arose on the dorsal surface and crept on the corpus until changing direction perpendicularly. This suggested that these veins were efficiently compressed between the tunica albuginea and the corpus cavernosum penis during erection. For a high pressure to be maintained in the cavernous spaces during erection, a closed system separated from the systemic circulation must be required. 1079 0018-1994 7 泌尿器科紀要 1075 33 泌尿器科紀要刊行会 Polster Erectile mechanism studied using penile vascular casts in the dog イヌ陰茎の血管鋳型からみた勃起のメカニズムについて 2433/141813 Hakamada, Masataka 2011/03/30 Nanostructured Co with large lattice extension and contraction was produced by electrodepositing Co on nanoporous Au. The Co deposited showed a low magnetic saturation of 76 emu/g and a high coercivity of 462 Oe. First-principles calculations showed that the magnetic moment of a Co atom is significantly decreased by lattice contraction. Therefore, the noteworthy magnetic properties of the Co deposited are attributed to the large lattice strain. Also, molecular dynamics simulation showed that the lattice extension and contraction of about 10% are generated in the overall Co crystal. This is in agreement with the experimental results of HRTEM observation. The constraint of the movement of Co atoms by the concave structure of nanoporous Au leads to a wide spread of large strain region. 0021-8979 8 Journal of Applied Physics 109 American Institute of Physics ab initio calculations Large-strain-induced magnetic properties of Co electrodeposited on nanoporous Au 2433/140114 Hoshi, Takeo 2008/09/29 52 1880-2818 数理解析研究所講究録 40 1614 京都大学数理解析研究所 Ultra-large-scale electronic structure theory and numerical algorithm (High Performance Algorithms for Computational Science and Their Applications) 2433/148415 Li, Xiaodong 2009/10/30 Scanning probe microscopy (SPM) has undergone rapid advancements since its invention almost three decades ago. Applications have been extended from topographical imaging to the measurement of magnetic fields, frictional forces, electric potentials, capacitance, current flow, piezoelectric response and temperature (to name a few) of inorganic and organic materials, as well as biological entities. Here, we limit our focus to mechanical characterization by taking advantage of the unique imaging and force/displacement sensing capabilities of SPM. This article presents state-of-theart in situ SPM nanomechanical testing methods spanning (1) probing the mechanical properties of individual one-dimensional nanostructures; (2) mapping local, nanoscale strain fields, fracture, and wear damage of nanostructured heterogeneous materials; and (3) measuring the interfacial strength of nanostructures. The article highlights several novel SPM nanomechanical testing methods, which are expected to lead to further advancements in nanoscale mechanical testing and instrumentation toward the exploration and fundamental understanding of mechanical property size effects in nanomaterials. 367 0883-7694 5 MRS BULLETIN 361 35 MATERIALS RESEARCH SOC In Situ Scanning Probe Microscopy Nanomechanical Testing 2433/148432 Suzuki, Motofumi 2009/10/30 In this study, we carry out high temperature glancing angle deposition HT-GLAD of Fe and Al on a heated substrate with trench patterns. When vapor is incident perpendicular to the trench direction, nanowhiskers grow only on the surface exposed to the vapor and not inside the trenches. When vapor is incident at a deposition angle larger than 80° on the sidewall of the trench and not on the substrate surface, nanowhiskers grow only on the sidewall because the condition of deposition at a high temperature and a large deposition angle is satisfied only for the sidewall. Thus, we succeed in the selective growth of nanowhiskers by controlling the geometrical deposition conditions. Further, we also discuss the effect of the local deposition geometry on the growth process. Geometrically selective growth by HT-GLAD is expected to be useful for growing nanowhiskers on nano- and microstructured substrates.

For example, artificial metallic periodic structures show potential for the construction of devices operating in the terahertz frequency regime. Here we demonstrate the fabrication of photodesigned terahertz devices that enable the real-time, wide-range frequency modulation of terahertz electromagnetic waves. These devices are comprised of a photo-induced, planar periodic-conductive structure formed by the irradiation of a silicon surface using a spatially modulated, femtosecond optical pulsed laser. We also show that the modulation frequency can be tuned by the structural periodicity, but is hardly affected by the excitation power of the optical pump pulse. We expect that our findings will pave the way for the construction of all-optical compact operating devices, such as optical integrated circuits, thereby eliminating the need for materials fabrication processes. 光でデザインするテラヘルツデバイス. 京都大学プレスリリース. 2011-10-18 2045-2322 Scientific Reports http://www.nature.com/srep/2011/111018/srep00121/pdf/srep00121.pdf 1 Nature Publishing Group Optical materials and structures Photo-designed terahertz devices 2433/145970 Hashida, M. 2008/10/30 Ablation of expanded polytetrafluoroethylene without disruption of the fine porous structure is demonstrated using an intense femtosecond-pulse laser. As a result of laser-matter interactions near ablation threshold fluence, high-energy ions are emitted, which cannot be produced by thermal dissociation of the molecules. The ion energy is produced by Coulomb explosion of the elements of (-CF_{2}-CF_{2-})n and the energy spectra of the ions show contributions from the Coulomb explosions of the ions rather than those of thermal expansion to generate high-energy ions. The dependence of ion energy on the laser fluence of a 180-fs pulse, compared with that of a 400-ps pulse, also suggests that the high-energy ions are accelerated by Coulomb explosion 13121 1094-4087 15 Optics Express 13116 17 Optical Society of America Non-thermal ablation of expanded polytetrafluoroethylene with an intense femtosecond-pulse laser 2433/149207 Ueki, Yoshitaka 2011/09/29 Measurements of the contact angles at the different temperatures of a molten lead–lithium eutectic alloy (PbLi) droplet on a silicon carbide (SiC) wall are needed for the research and development both of a magnetic confinement fusion (MCF) and an inertia confinement fusion (ICF) blankets. PbLi coolant/breeder flows in the coolant channel, which is made of the SiC walls, and will experience a flow slip at the wall, called as a magnetohydrodynamic (MHD) slip flow. The ICF blanket adopts a molten PbLi film flow along the first wall made of SiC. The PbLi contact angle database is necessary as the thermal property for numerically predicting the behavior of the flowing molten PbLi film. This study attempts the measurement of the contact angles between the molten PbLi and the various SiC surfaces. For example, in order to examine the initial PbLi wettability, we measured the contact angles of a chemical vapor deposition (CVD) SiC, a nano-infiltration and transient eutectic-phase (NITE) SiC/SiC composites, and a NITE SiC in an inert atmosphere. We obtained the contact angle database of the molten PbLi, varying the temperature of PbLi from 250 to 400 °C, on a surface-polished as well as an unpolished SiC. 2300 0920-3796 9-11 Fusion Engineering and Design 2297 86 Elsevier B.V. Lead–lithium Contact angle measurement of molten lead–lithium on silicon carbide surfaces 2433/151697 Mizuta, Seiko 2011/11/29 We examined the growth of testate amoebae preying on Microcystis whose physiological states were different in laboratory experiments and a hypertrophic pond. We prepared three experimental systems using water samples dominated by Microcystis aeruginosa: light incubation (control), dark incubation (dark), and light incubation with addition of nitrogen and phosphorus (+NP). In all the systems, the colony density of M. aeruginosa decreased slightly during incubation. Physiological activity of phytoplankton as determined by chlorophyll fluorescence was high and almost constant in the control and +NP systems, whereas it decreased in the dark system. Cell densities of testate amoebae increased in the control and +NP systems, whereas in the dark system they remained low. Thus, growth of the amoebae was low in the systems where physiological activity of Microcystis was low. In a hypertrophic pond, cell density of testate amoebae increased and remained high when M. aeruginosa predominated. Cell density of testate amoebae increased remarkably, simultaneously with the increases in M. aeruginosa colony density and phytoplankton physiological activity. We also found a significant correlation between densities of M. aeruginosa colonies and testate amoebae. We suggested that the physiological activity of Microcystis is one important factor affecting the growth of testate amoebae grazing on Microcystis. 211 1439-8621 3 Limnology 205 12 Springer Microcystis Grazing on Microcystis (Cyanophyceae) by testate amoebae with special reference to cyanobacterial abundance and physiological state 2433/75577 1957/10/31 47 0023-6071 1-2 Bulletin of the Institute for Chemical Research, Kyoto University 41 35 Institute for Chemical Research, Kyoto University List of Scientific Papers : Published in Other Periodicals or Books by the Members of the Institute and their Co-workers during the Year 1956 2433/75833 1961/07/31 248 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 241 39 Institute for Chemical Research, Kyoto University List of the Articles Published in Other Journals (1960) 2433/155954 KAWAKATSU, Masaharu 1972/03/15 122 0452-9987 3-4 Contributions from the Biological Laboratory, Kyoto University 115 23 京都大学教養部生物学教室 Report on Freshwater Planaria from Borneo 2433/143611 Leopold, Estella B. 2011/04/12 18 1349-872X SANSAI : An Environmental Journal for the Global Community 5 5 Graduate School of Global Environmental Studies, Kyoto University Keeping the land alive and well : The 2010 International Cosmos Prize commemorative lecture 2433/156801 Wickham, Shelley F J 2011/02/27 Controlled motion at the nanoscale can be achieved by using Watson-Crick base-pairing to direct the assembly and operation of a molecular transport system consisting of a track, a motor and fuel, all made from DNA. Here, we assemble a 100-nm-long DNA track on a two-dimensional scaffold, and show that a DNA motor loaded at one end of the track moves autonomously and at a constant average speed along the full length of the track, a journey comprising 16 consecutive steps for the motor. Real-time atomic force microscopy allows direct observation of individual steps of a single motor, revealing mechanistic details of its operation. This precisely controlled, long-range transport could lead to the development of systems that could be programmed and routed by instructions encoded in the nucleotide sequences of the track and motor. Such systems might be used to create molecular assembly lines modelled on the ribosome. 169 1748-3395 3 Nature nanotechnology 166 6 Nature Publishing Group Molecular machines and motors Direct observation of stepwise movement of a synthetic molecular transporter. 2433/56375 Supiandi, Sabiham 1989/11/29 The micromorphology of peats was studied in order to characterize the various stages of decomposition and to describe the overall change of organic matter after deposition. The fallen plant materials consist of leaves, wood blocks, branches and twigs, and they are categorized as litter. Several microfabrics, including fibric, hemic and sapric materials, occur in the course of decomposition. Fibric material is characterized by tissues of recognizable botanical origin, while the hemic and sapric materials are characterized by mainly unrecognizable tissues. Peats covered by dense forest are mostly characterized by fibric peat in the bottom layer, which is mainly derived from ferns and grasses. In the upper layers these peats are commonly hemic or sapric peats containing many wood blocks derived from the former vegetation. In cultivated areas, thin peat layers are categorized as sapric peats. The macro- and microorganisms attacking the plant debris control the process of micromorphological change of organic matter and hasten the decomposition of fallen-plant materials. However, the degree of decomposition of peats is closely related to the water contents of organic materials. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 351 0563-8682 3 東南アジア研究 339 27 京都大学東南アジア研究センター Studies on Peat in the Coastal Plains of Sumatra and Borneo: Part III: Micromorphological Study of Peat in Coastal Plains of Jambi, South Kalimantan and Brunei 2433/87352 Matsuda, Kazunari 2008/04/29 We studied the spectral diffusion and exciton fine structures of single-walled carbon nanotubes (SWNTs) by using single carbon nanotube spectroscopy. Two types of single nanotube photoluminescence (PL) spectra were observed at temperatures below 50 K, which are double peaks with spectral diffusion and a single peak without spectral diffusion. The spectral diffusion that occurs in the lower energy peak of the split PL spectrum is associated with the quantum-confined Stark effect. Our observations suggest that symmetry breaking caused by the strong local electric field enables us to observe the dark exciton state below the bright exciton state in single SWNTs. 1098-0121 19 Physical Review B 77 American Physical Society carbon nanotubes Exciton fine structure in a single carbon nanotube revealed through spectral diffusion 2433/87354 Matsuda, Kazunari 2007/12/30 We studied the temperature and excitation intensity dependence of exciton luminescence in individual single-walled carbon nanotubes (SWNTs) using single nanotube photoluminescence (PL) spectroscopy. The linear temperature dependence of the PL linewidth in a single SWNT implies that the exciton dephasing is dominated by the interaction between the exciton and the phonon mode with very low energy under lower-excitation conditions. Saturation of the PL intensity and broadening of the PL linewidth in a single SWNT occur simultaneously with an increase in excitation laser intensity. Our findings show that the rapid exciton-exciton annihilation through multiparticle Auger recombination broadens the homogeneous PL linewidth. 1098-0121 3 Physical Review B 77 American Physical Society Auger effect Exciton dephasing and multiexciton recombinations in a single carbon nanotube 2433/158044 Kato, Ayako 2012/02/22 Cell-sized water-in-oil droplet covered by a lipid layer was used to understand how lipid membranes affect biochemical systems in living cells. Here, we report a remarkable acceleration of gene expression in a cell-sized water-in-oil droplet entrapping a cell-free translation system to synthesize GFP (green fluorescent protein). The production rate of GFP (V(GFP)) in each droplet remained almost constant at least for on the order of a day, which implies 0(th)-order reaction kinetics. Interestingly, V(GFP) was inversely proportional to radius of droplets (R) when R is under 50 μm, and V(GFP) in droplets with R ∼ 10 μm was more than 10 times higher than that in the bulk. The acceleration rates of GFP production in cell-sized droplets strongly depended on the lipid types. These results demonstrate that the membrane surface has the significant effect to facilitate protein production, especially when the scale of confinement is on the order of cell-size. 2045-2322 Scientific reports 2 Nature Publishing Group Biophysics Cell-Sized confinement in microspheres accelerates the reaction of gene expression. 2433/142515 Hirai, Toshiro 2011/07/30 We fabricate LiCoO[2]/helical nanocarbon (HCN) composites by forming HCNs on LiCoO[2] on which iron oxides (Fe[2]O[3] or Fe[3]O[4]) are dispersed (LiCoO[2](Fe[2]O[3]) or LiCoO[2](Fe[3]O[4])) as catalysts for HCN formation, and estimate their electrochemical properties. Granular nanocarbons form on LiCoO[2](Fe[2]O[3]) and LiCoO[2](Fe[3]O[4]) at 350 °C although HCNs of about 100 nm in diameter form on LiCoO[2](Fe[2]O[3]) at 450 °C. Transmission electron microscopy and energy dispersive X-ray spectroscopy measurements show that HCNs consist of stacked graphene layers for LiCoO[2](Fe[2]O[3])/HCN composites fabricated at 450 °C. On the other hand, several-nm-thick tetragonal layer exists on the LiCoO[2] substrate and amorphous nanocarbons form on the tetragonal layer for LiCoO[2](Fe[2]O[3])/HCN and LiCoO[2](Fe[3]O[4])/HCN composites fabricated at 350 °C. X-ray diffraction measurements suggest that Fe[2]O[3] and Fe[3]O[4] do not completely inhibit LiCoO[2] decomposition. Cathodes containing LiCoO[2](Fe[2]O[3])/HCN or LiCoO[2](Fe[3]O[4])/HCN fabricated at 350 °C improve rate capability of lithium cells. However, this rate capability is not better than that of cathodes containing a mixture of LiCoO[2] and acetylene black. 6968 0378-7753 16 Journal of Power Sources 6964 196 Elsevier B.V. Lithium-ion cell Fabrication of LiCoO2/helical nanocarbon composites and their effect on lithium cell performance 2433/144637 ARYUTHAKA, CHITTIMA 2009/10/30 Two transplanted mangrove forests in the Inner Gulf of Thailand were selected for this study. One was on the mud flat in Samut Songkhram Province and another was on sand flat in Phetchaburi Province. There were differences in species and ages of mangroves transplanted in the study sites. Sediment samples were collected randomly for analyses of meiobenthic communities and granulometric properties. Samples were collected from under 7-year old & 4 - year old Avicennia alba and 4 - year old Sonneratia caseolaris stands in Samut Songkhram site and from 7 - years & 1- year old Rhizophora apiculata and 7 - year old Avicennia alba stands. Average meiobenthic densities (ind.10 cm-2) varied, ranging from 452.62 ± 23.24 - 654 ± 59.42 in Samut Songkhram and 382.96 ± 45.38 - 627.30 ± 56.89 in Phetchaburi sites. There were significant differences in their densities among samples. Higher densities occurred in samples under older transplanted tree stands in both sites. Also, within stands of the same age of transplanted trees, meiofaunal average densities were different between mangrove species. In Samut Songkhram site, average density in Avicennia alba samples (540 ± 42) was higher than that in Sonneratia caseolaris samples (453 ± 23). Also, this value in Avicennia alba samples (627 ± 57) was higher than that in Rhizophora apiculata samples (587 ± 44) in Phetchaburi site. For meiobenthic composition, there were a total of eight taxa recorded, namely nematodes, copepods, polychaetes, oligochaetes, halacarids, tardigrads, kinorynchs and tanaids. According to an average percentage of their total abundances in Samut Songkhram and Phetchaburi mangrove forests, nematodes were the most dominant with values of 92.74 ± 1.0 and 93.21 ± 0.76%, while harpacticoid copepods were second with values of 6.51 ± 0.47 and 6.42 ± 0.69 in each sites, respectively. Analysis of meiobenthic assemblages using non-parametric multi dimensional scaling showed differences between sampling sites and transplanted mangrove species. Minor meiobenthic taxa, such as oligochaetes, halacarids, tardigrads, kinorynchs and tanaids, also showed significant differences which could be related to habitats, tree species and age of mangrove stand. Results of the present study reveal that meiobenthic assemblages can be used to detect subtle environmental effects and are, therefore, ideal organisms to use to monitor the mangrove recovery. 74 0389-6609 Publications of the Seto Marine Biological Laboratory.

Here we separated brain neurons from dissociated planarian head cells by fluorescence activated cell sorting (FACS), and characterized them by single cell PCR analysis and cell culture. Dissociated cells were labeled with three different fluorescent dyes, Hoechst 33258, Merocyanine 540, and Propidium Iodide (PI), and fractioned by FACS. Interestingly, we have succeeded in identifying a cell fraction specific to the head, which we have named the head-abundant cell fraction (HAC). Most of the HAC expressed neuron-specific genes and proteins. When they were cultured in vitro, they showed an ability to extend neurites on several types of extracellular matrices (ECMs), and, depending on the ECM type used, presented a high level of plasticity in morphology and gene expression. 1265 0289-0003 11 Zoological Science 1257 19 Zoological Society of Japan planarian Cultivation and characterization of planarian neuronal cells isolated by fluorescence activated cell sorting (FACS) 2433/72803 Suzuki, Motofumi 2008/05/18 Using a dynamic oblique angle deposition technique, we demonstrate the direct formation of Ag nanorods with quasi-parallel major axes on a template layer of oxide having a strongly anisotropic surface morphology. The optical properties of the nanorods are tuned by varying the deposition conditions without any pre- or post-treatment, and the resulting Ag nanorod arrays exhibit high surface-enhanced Raman scattering (SERS) activity. In addition to high macroscopic uniformity over a large area, our nanorod arrays contain a high density of isolated nanorods. Using the optimum Ag nanorod arrays, the SERS imaging of the microdroplets of a rhodamine 6G solution is successfully demonstrated. The space resolution of the imaging is of the order of at least a few µm.

When vapor is incident perpendicular to the trench direction, nanowhiskers grow only on the surface exposed to the vapor and not inside the trenches. When vapor is incident at a deposition angle larger than 80° on the sidewall of the trench and not on the substrate surface, nanowhiskers grow only on the sidewall because the condition of deposition at a high temperature and a large deposition angle is satisfied only for the sidewall. Thus, we succeed in the selective growth of nanowhiskers by controlling the geometrical deposition conditions. Further, we also discuss the effect of the local deposition geometry on the growth process. Geometrically selective growth by HT-GLAD is expected to be useful for growing nanowhiskers on nano- and microstructured substrates.

Microtubules usually aggregate only above the helical thickenings or bands throughout the the development of primary xylem cells but not above the areas where no secondary wall deposition occurs, and run parallel to the micronbrils within the bands. In view of their general distribution throughout cell organelles, plasmalemma particles of primary xylem cells visible by freeze etching technique are questionable to be considered as the enzyme complex involved in the synthesis and orientation of cellulose micronbrils of secondary wall. Thus, microtubules may be considered as the only organella to determine the orientation of micronbrils. A possible association of microtubules and Golgi-derived vesicles during wall thickening is assumed by the fact that the position and alignment of microtubules are closely related to those of Golgi-derived vesicles. It seems that the microtubules play a part for the incorporation of Golgi-derived vesicles .into the destined site of cell wall. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 69 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 48 57 Wood Research Institute, Kyoto University Fine Structure of Secondary Wall Thickening and a Role of Microtubules in Primary Xylem Cells of Poplar 2433/76951 kawaguchi, Akiyoshi 1981/11/30 292 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 284 59 Institute for Chemical Research, Kyoto University Radiation-Induced Phase Transition of Paraffins (Special Issue on Polymer Chemistry, XVI) 2433/52254 SUZUKI, Yasuhiro 1974/03/30 A simple in vitro way of examining materials interfering with the formation of stable bubbles from lung surfactant was presented. The method consists of agitation of liquid extracts with a magnetic stirrer for l hr and examination of bubble stability under a microscope. Bubble stability of perfused lung homogenate from adult rat was significantly greater than that which was not perfused. Foams from isolated surface-active material and lung homogenate of fetal rat showed high stability but those from adult rat lung homogenate showed low stability. In analysis of lipid composition by thin layer chromatography, no significant differences were found among foams from various extracts and fractions from purification steps of surfactant in spite of much difference among the extracts and fractions themselves. Contamination with materials, which were precipitated by sucrose gradient ultracentrifugation of adult rat lung homogenate at 48,000g, inhibited stable bubble formation in half-purified surface-active material from adult rat lung and in fetal lung homogenate. From these results, it is suspected that inhibiting factor (s) are present in adult rat lung homogenate which interfere with stable bubble formation from surfactant, even if the surfactant itself is sufficient in amount. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 169 0009-3378 2 京都大学結核胸部疾患研究所紀要 161 7 京都大学結核胸部疾患研究所 STUDIES ON FACTORS INFLUENCING STABLE BUBBLE FORMATION FROM LUNG HOMOGENATE 2433/77204 Maki, Toshio 1988/03/15 251 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 242 65 Institute for Chemical Research, Kyoto University Flow Properties and Fiber Formation of Alumina Sols 2433/65038 Matsui, Masafumi 2005/06/29 A new species of torrent-dwelling bufonid frog of the genus Ansonia is described from the Isthmus of Kra, Thailand.

Mapping of the genome sequence to the Ciona 14 haploid chromosomes is essential for future studies of the genome-wide control of gene expression in this basal chordate. Here we describe an efficient protocol for fluorescent in situ hybridization for mapping genes to the Ciona chromosomes. We demonstrate how the locations of two BAC clones can be mapped relative to each other. We also show that this method is efficient for coupling two so-far independent scaffolds into one longer scaffold when two BAC clones represent sequences located at either end of the two scaffolds. 157 0289-0003 2 Zoological Science 153 21 Zoological Society of Japan ascidians Fluorescent in situ hybridization to ascidian chromosomes 2433/109926 Sano, Atsushi 2009/05/26 The ability of lithium-ion diffusion in carbon nanobeads (CNBs) was investigated by the microelectrode method [cyclic voltammetry, constant current charge/discharge, potential step, and potentiostatic intermittent titration technique (PITT)]. CNBs showed high rate discharge capacities of over 1000 C. CNB heat-treated at 1000, 1500, and 2000°C showed a higher charge ability than 2800°C. The lithium-ion diffusion coefficient (DLi+) in CNBs was investigated by PITT. DLi+ was different in the intercalation and deintercalation directions in 1000, 1200, and 1500°C CNBs. DLi+ of the intercalation and the deintercalation showed different potential dependencies. The 1200°C heat-treated CNB showed the highest DLi+ in the direction of intercalation.

The Co particle size is decreased to a certain degree by varying the concentration of starting materials and by adding nucleating agents. The electrochemical behavior of propylene glycol is investigated by in situ measurements of mixed potential to understand the formation of Co nanoparticles in polyol systems. The mixed potential decreases with an increase in temperature and in the presence of NaOH, which suggests the faster decomposition of propylene glycol. It also shifts abruptly to a more negative value when nucleating agents are added. This indicates that nucleating agents catalyze both the oxidation reaction of propylene glycol and the reduction reaction of Co(II) species, as well as aid in the formation of Co nanoparticles as heterogeneous nucleation sites.

The mouth of each fish opened with a slight but definite distortion toward the right or left side, depending on the individual. Right-opening mouth (dextral) fish had a right lower jaw that was more protruded than the left one, and left-opening (sinistral) fish had a more protruded left lower jaw. No fish had laterally symmetric lower jaws, indicating that the asymmetry was different from ‘fluctuating asymmetry’. These fish used either the right or left side of the mouth when picking up food from the bottom, but neither dextral nor sinistral individuals used one side more frequently than the other side. The mouth asymmetry, however, was related to the stationary posture: dextral fish stayed on the bottom with the line of their bodies curved to the right more frequently than to the left, and vice versa for the sinistral fish. Genetics of the morph phenotype were investigated by observing the frequencies of morphs in F1 under captive breeding. Mouth dimorphism seems to be determined by the Mendelian one-locus-two-alleles system, in which dextrality is dominant over sinistrality and the dominant gene acts as the lethal one when in a homozygote. 1325 0289-0003 9 Zoological Science 1321 17 Zoological Society of Japan Asymmetry of Mouth Morph of a Freshwater Goby, Rhinogobius Flumineus 2433/109942 Oyama, Munetaka 2009/01/30 A seed-mediated growth method for surface modification was applied to the attachment of gold nanoparticles (AuNPs) to glassy carbon (GC) surfaces. By simply immersing a GC plate at first into a seed solution containing 4 nm Au nano-seed particles and then into a growth solution containing HAuCl4, ascorbic acid and cetyltrimethyammonium bromide, AuNPs could be successfully attached to the GC surface via the growth of nanoparticles. A possible control of the size and density of AuNPs on GC was examined by observing surface images with a field-emission scanning electron microscope (FE-SEM) after several preparations with different immersion times. Compared with previous results on the growth of AuNPs on indium tin oxide (ITO) surfaces, it was characteristic that the AuNPs attached to GC surfaces exhibited smaller size and higher density as well as a flatter and non-crystal-like morphology. In addition, for performing the dense attachment of regular nano-sized AuNPs on GC surfaces, immersion for 2 h into the growth solution was sufficient. Longer immersion for 24 h caused an irregular growth of bold Au micro-crystals, while 24 h was necessary in the case of AuNPs on ITO surfaces. Shorter seeding and growth times were found to be effective for a sparse attachment of smaller Au nanoparticles whose size was ca. 20 nm. It was clarified that the seed-mediated growth method for surface modification was valid for fabricating a nanointerface composed of AuNPs on GC surfaces. 253 0910-6340 2 ANALYTICAL SCIENCES 249 25 Japan Society for Analytical Chemistry Surface Observation for Seed-mediated Growth Attachment of Gold Nanoparticles on a Glassy Carbon Substrate 2433/122506 永田, 一夫 1979/08/30 The absorption of 3H-adriamycin through rat urinary bladder and the subsequent distribution and excretion of the absorbed adriamycin were studied. Male Wistar rats weighing 300 to 350 g were used. A ureter was exposed and half-incised transversely, using a stereoscopic microscope. A polyethylene tube with an outer diameter of 0.024 inches was inserted through this incision, in the same manner as an ureterostomy, and the opposite kidney was extirpated. As for the bile, the same tube was inserted into the bile duct. Then, 3H-adriamycin (10.79µCi/0.3 ml/300µg adriamycin) was injected into the bladder. Following the instillation of the adriamycin over an one hour period, the filled bladder was excised. Thereafter the urine and bile were collected every 3 hours for the next 12 hours. In another group, the liver, spleen, kidney and heart were extirpated I and 12 hours after the injection, respectively. The following results were obtained. 1) The recovery rate of the residual 3H-adriamycin in bladder one hour after instillation was 81.7% and the vesical tissue level was 175.9µg/g on an average. 2) The tissue concentrations of 3H-adriamycin one hour after the injection were 0.19µg//g in the liver, 0.36,ug/g in the spleen, 0.31µg/g in the kidney, and 0.21µg//g in the heart. 3) The recovery rate of 3H-adriamycin into the urine was 0.66%, and the rate of it into bile was 4.22% during 12 hours. 4) The tissue concentrations of 3H-adriamycin 12 hours after the injection were 0.52µg/g in the liver, 0.67µg/g in the spleen, 0.49µg/g in the kidney and 0.33µg/g in the heart.

Four stones were removed and weighed 105.6 g, 104.0 g, IS.S g and 16.5 g, total 244.6 g, and there were the fiftieth giant stone in our country. The compositions were proved to be magnesium-ammonium-phosphate-oxalate with ammonium-urate by the method of infrared spectrophotometry (KBr). Each calculus was then split open with a scalpel to give two approximately equal halves, and fractured surfaces were examined with the scanning electron microscope after coating with Au-Pd. 1058 0018-1994 12 泌尿器科紀要 1053 19 泌尿器科紀要刊行会 A CASE REPORT OF MULTIPLE GIANT VESICAL CALCULI AND THE SCANNING ELECTRON MICROSCOPICAL STUDY 多発性巨大膀胱結石とその走査電子顕微鏡学的研究 2433/128766 Teramura, Kentaro 2010/06/07 ATaO3 (A = Li, Na, K) compound oxides exhibit photocatalytic activity for the reduction of CO2 in the presence of H2. Only CO gas was generated over all samples under photoirradiation. The photocatalytic activity was higher in the order corresponding to KTaO3, NaTaO3 and LiTaO3 (LiTaO3 > NaTaO3 > KTaO3). The order of the photocatalytic activities was consistent with that of the Eg (optical gap) values. After 24 h of photoirradiation, the amount of evolved CO reached 0.42 μmol g−1 over LiTaO3. TPD experiments indicated that the broad peak which is assigned to chemisorbed CO2 gas was observed at 573 K in the case of LiTaO3. On the contrary, there was no peak in the spectra of NaTaO3 and KTaO3. The amount of evolved CO gas almost strongly depends on the amount of chemisorbed CO2 in the case of ATaO3 (A = Li, Na, K). In addition, the photocatalytic activity increased with increasing the calcination temperature of LiTaO3. This means that a smooth charge separation in a LiTaO3 photocatalyst and chemisorption of CO2 on the surface contribute to effective reduction of CO2 in the presence of H2. 568 0926-3373 3-4 Applied Catalysis B: Environmental 565 96 Elsevier B.V.

In one type, the stress concentration was at the interface edge, while in the other type, it was in the interior. In the former, a crack was initiated at the Cu/Si interface edge under a stress concentration of about 1 GPa extending over 20–30 nm. In the latter, using a cantilever specimen with a step, a crack was initiated in the interior at the Cu/Si interface at a stress concentration of about 1 GPa extending over 60 nm, which coincides fairly well with that at the interface edge. These results demonstrate the applicability of a unified criterion for interface crack initiation, though the interior is slightly more resistant to cracking. 4803 0921-5093 18-19 Materials Science and Engineering: A 4796 527 Elsevier B.V.

The present study was performed to see if movement of the external ears in a human embryo could be explained by differential growth. [Methods]In all, 171 samples between Carnegie stage (CS) 17 and CS 23 were selected from MR image datasets of human embryos obtained from the Kyoto Collection of Human Embryos. The three-dimensional absolute position of 13 representative anatomical landmarks, including external and internal ears, from MRI data was traced to evaluate the movement between the different stages with identical magnification. Two different sets of reference axes were selected for evaluation and comparison of the movements. [Results]When the pituitary gland and the first cervical vertebra were selected as a reference axis, the 13 anatomical landmarks of the face spread out within the same region as the embryo enlarged and changed shape. The external ear did move mainly laterally, but not cranially. The distance between the external and internal ear stayed approximately constant. Three-dimensionally, the external ear located in the caudal ventral parts of the internal ear in CS 17, moved mainly laterally until CS 23. When surface landmarks eyes and mouth were selected as a reference axis, external ears moved from the caudal lateral ventral region to the position between eyes and mouth during development. [Conclusion]The results indicate that movement of all anatomical landmarks, including external and internal ears, can be explained by differential growth. Also, when the external ear is recognized as one of the facial landmarks and having a relative position to other landmarks such as the eyes and mouth, the external ears seem to move cranially. 1746-160X Head & face medicine 8 BioMed Central Ltd External ear Movement of the external ear in human embryo. 2433/161794 Tanaka, Rina 2011/07/30 To ensure the maintenance of tissues in mammals, cell loss must be balanced with cell production, the proliferative activity being different from tissue to tissue. In this article, the authors propose a new method for the quantification of the proliferative activity, defined as the S-phase fraction of actively cycling cells, by dual labeling with fluorescence and peroxidase immunohistochemistry using BrdU (marker of S-phase) and Ki67 antibodies (marker of G(1)-, S-, G(2)-, and M-phases) after a one-step antigen retrieval. In the generative cell zones of fundic and pyloric glandular stomachs, where the majority of cells were cycling, the authors measured a proliferative activity of 31%. In the epithelium of the forestomach and the skin, where cycling cells are intermingled with G(0) and differentiated cells, proliferative activities were 21% and 13%, respectively. In the adrenal cortex, in which cycling cells were sparsely distributed, the proliferative activity reached 32%. During the regenerative process in the skin after a lesion, the proliferative activity increased in proximity to the wound. The present one-step dual-labeling method has revealed that the proliferative activity is different between tissues and depends on the physiological or pathological state. 798 0022-1554 8 The journal of histochemistry and cytochemistry : official journal of the Histochemistry Society 791 59 SAGE Publications Accurate determination of S-phase fraction in proliferative cells by dual fluorescence and peroxidase immunohistochemistry with 5-bromo-2'-deoxyuridine (BrdU) and Ki67 antibodies. 2433/163420 Balela, Mary Donnabelle L. 2010/10/30 We report a fast preparation method for cobalt (Co) nanowires of about 59 nm in diameter and up to 30 μm in length by electroless deposition in an aqueous solution at room temperature under an external magnetic field. The reduction process is observed by in situ monitoring of mixed potentials. When the mixed potential decreases below the oxidation-reduction potential of the Co(II)/Co redox pair (ECo(II)/Co), spherical Co nanoparticles are formed in the solution and then magnetized by the magnetic field. Attractive dipolar interactions are generated along the magnetic field direction, which results in the self-assembly of Co nanoparticles into nanowires.

SEM-EDX analysis is additionally performed for the specimen treated by the ethanol diluted ionic liquid. As an example of the insulator specimen, we analyze volcanic ash particles, and succeed to discriminate the elemental composition difference of a specimen surface within 10 μm2 micro area. Though a clear secondary electron image of the volcanic ash particle of which diameter is less than 10 μm can be obtained without electric conductive treatment, particles of diameter larger than 20 μm are needed to be treated by the diluted ionic liquid to avoid the charge-up effects. 951 0525-1931 11 BUNSEKI KAGAKU 947 61 Japan Society for Analytical Chemistry SEM-EDX 希釈イオン液体による絶縁性試料のSEM-EDX分析 -火山灰への応用- SEM-EDX Analysis of Insulator Specimens by Diluted Ionic Liquid -Application to Volcanic Particles- 2433/171915 Nakagawa, Keiyu 2011/09/29 Using TEM observation and Vickers micro-hardness measurements, this study investigated microstructural changes resulting from aging treatment of ultrafine-grained (UFG) Al-0.5%Si alloy fabricated with a six-cycle accumulative roll-bonding (ARB) process, which includes severe plastic deformation. Results show that the mean grain size of the UFGed Al-0.5%Si alloy produced by the ARB was 253 nm. The hardness of specimens aged at 373 K and 423 K decreased monotonously with increasing aging time in the initial stage of aging. The hardness value of the specimen aged at 373 K then became higher than the value of the specimen aged at 423 K after 10 ks. TEM observation revealed that the mean grain size of the UFG specimen aged at 373 K was less than that of the specimen aged at 423 K. Moreover, results confirmed that Si phase precipitates on the {111} planes on the matrix in the UFG specimen aged at 373 K and 423 K. The mean size of Si-phase in the UFG increased with aging time. The Si phase formation in the UFG specimen aged at 373 K is less than that of 423 K in long-term aging. However, the formation of Si phase on the grain boundaries is more conspicuous than in UFG specimens aged at 373 K and 423 K. These results suggest that restraint of the growth of UFG with aging resulted from Si phase precipitation on the grain boundary and lowering of the aging temperature. Moreover the formation of Si-phase in the UFG suggests precipitation hardening in the ARB-processed Al-Si alloy. 1859 1345-9678 10 Materials transactions 1853 52 Japan Institute of Metals aluminum-0.5%silicon alloy Effect of Aging Treatment on Ultra-Fine Grains and Si-Phase in Al-0.5%Si Alloy Fabricated by ARB Process 2433/74704 Tabata, Yasuhiko 1988/01/23 Kyoto University 高分子微粒子のマクロファージによる貪食とマクロファージの抗腫瘍活性化 Macrophage phagocytosis of polymer microspheres and antitumor activation of macrophages 2433/53271 TANAHASHI, Mitsuhiko 1990/12/28 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 117 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 49 77 Wood Research Institute, Kyoto University Characterization and Degradation Mechanisms of Wood Components by Steam Explosion and Utilization of Exploded Wood 2433/53183 WATANABE, Ugai 1998/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 47 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 1 85 Wood Research Institute, Kyoto University shrinkage Shrinking and Elastic Properties of Coniferous Wood in Relation to Cellular Structure 2433/77964 佐野, 光 2009/03/23 京都大学 自己集積化単分子膜 シリコンに直接結合した自己集積化単分子膜の形成とその応用 2433/65598 Ikawa, Taiji 2008/07/23 Kyoto University アゾベンゼン アゾベンゼンを含有する高分子化合物へのナノスケール光加工 Nanoscale Photofabrication on Azobenzene-Containing Polymers 2433/163775 Matsui, Ryosuke 2012/10/30 The domestic chicken is an attractive model system to explore the development and function of brain circuits. Electroporation-mediated and retrovirus (including lentivirus) vector-mediated gene transfer techniques have been widely used to introduce genetic material into chicken cells. However, it is still challenging to efficiently transduce chicken postmitotic neurons without harming the cells. To overcome this problem, we searched for a virus vector suitable for gene transfer into chicken neurons, and report here a novel recombinant virus vector derived from avian adeno-associated virus (A3V). A3V vector efficiently transduces neuronal cells, but not non-neuronal cells in the brain. A single A3V injection into a postembryonic chick brain allows gene expression selectively in neuronal cells within 24 hrs. Such rapid and neuron-specific gene transduction raises the possibility that A3V vector can be utilized for studies of memory formation in filial imprinting, which occurs during the early postnatal days. A3V injection into the neural tube near the ear vesicle at early embryonic stage resulted in persistent and robust gene expression until E20.5 in the auditory brainstem. We further devised an A3V-mediated tetracycline (Tet) dependent gene expression system as a tool for studying the auditory circuit, consisting of the nucleus magnocellularis (NM) and nucleus laminaris (NL), that primarily computes interaural time differences (ITDs). Using this Tet system, we can transduce NM neurons without affecting NL neurons. Thus, the A3V technology complements current gene transfer techniques in chicken studies and will contribute to better understanding of the functional organization of neural circuits. 1932-6203 11 PloS one 7 Public Library of Science Avian adeno-associated virus vector efficiently transduces neurons in the embryonic and post-embryonic chicken brain. 2433/172452 Ohno, Sachi 2011/11/29 The rostral sector of the posterior thalamic nuclei (POm) is, together with the ventral posterior nuclei (VP), involved in somatosensory information processing in rodents. The POm receives inputs from the spinal cord and trigeminal nuclei and projects to the primary somatosensory (S1) cortex and other cortical areas. Although thalamocortical axons of single VP neurons are well known to innervate layer (L) 4 of the S1 cortex with distinct columnar organization, those of POm neurons have not been elucidated yet. In the present study, we investigated complete axonal and dendritic arborizations of single POm neurons in rats by visualizing the processes with Sindbis viruses expressing membrane-targeted fluorescent protein. When we divided the POm into anterior and posterior parts according to calbindin immunoreactivity, dendrites of posterior POm neurons were wider but less numerous than those of anterior neurons. More interestingly, axon fibers of anterior POm neurons were preferentially distributed in L5 of the S1 cortex, whereas those of posterior neurons were principally spread in L1 with wider and sparser arborization than those of anterior neurons. These results suggest that the POm is functionally segregated into anterior and posterior parts and that the 2 parts may play different roles in somatosensory information processing. 2857 1047-3211 12 Cerebral cortex 2840 22 Oxford University Press calbindin immunoreactivity A morphological analysis of thalamocortical axon fibers of rat posterior thalamic nuclei: a single neuron tracing study with viral vectors. 2433/134640 Takashima, Yohei 2011/01/25 Chemosensors detect a single target molecule from among several molecules, but cannot differentiate targets from one another. In this study, we report a molecular decoding strategy in which a single host domain accommodates a class of molecules and distinguishes between them with a corresponding readout. We synthesized the decoding host by embedding naphthalenediimide into the scaffold of an entangled porous framework that exhibited structural dynamics due to the dislocation of two chemically non-interconnected frameworks. An intense turn-on emission was observed on incorporation of a class of aromatic compounds, and the resulting luminescent colour was dependent on the chemical substituent of the aromatic guest. This unprecedented chemoresponsive, multicolour luminescence originates from an enhanced naphthalenediimide-aromatic guest interaction because of the induced-fit structural transformation of the entangled framework. We demonstrate that the cooperative structural transition in mesoscopic crystal domains results in a nonlinear sensor response to the guest concentration. 「ちえのわ」型ナノ細孔を用いたセンサー開発に成功： 動き、捕まえ、光って知らせるナノ多孔体. 京都大学プレスリリース. 2011-01-26. 2041-1723 1 Nature communications 2 Nature Publishing Group Molecular decoding using luminescence from an entangled porous framework. 2433/137412 Yoshino, Hiroaki 2011/01/30 The potassium-doped Co3O4 catalysts were prepared by impregnation of potassium sources on commercial cobalt carbonate and on the precursors synthesized by homogeneous precipitation, combustion with glycine, gradual oxidation, and hydrothermal methods. The activities of these catalysts for the direct decomposition of nitrous oxide in the presence of oxygen with or without water vapor were examined. The effects of potassium sources on the catalyst activity were also examined by impregnation of various potassium salts on commercial cobalt carbonate. The catalyst prepared by impregnation of an aqueous solution of KOH on commercial cobalt carbonate showed the highest activity. The catalysts prepared by various methods were analyzed by powder X-ray diffraction, N2 adsorption, scanning electron microscope, temperature-programmed reduction with H2, temperature-programmed desorption of O2, and X-ray photoelectron spectroscopy. These results suggest that crystallite size and reduction property are key factors for the activity of the catalyst for the direct decomposition of nitrous oxide in the presence of oxygen. 805 0022-2461 3 Journal of Materials Science 797 46 Springer Science+Business Media, LLC.

The CS/PEI nanoparticles were prepared by the emulsifier-free emulsion polymerization of methyl methacrylate monomer induced by a small amount of t-butyl hydroperxide in the presence of different concentrations of PEI mixed with CS. The resulting nanoparticles were characterized by their surface properties and buffering capacity. In vitro gene transfection was also evaluated. The introduction of PEI affected the surface charge, dispersing stability and buffering capacity of the nanoparticles. The CS/PEI nanoparticles formed a complex upon mixing with a plasmid DNA of luciferase. The complex enhanced the level of gene transfection and prolonged the time period of expression for MSCs, compared with those of plasmid DNA–original CS and PEI nanoparticles. Cytotoxicity of CS/PEI complexes with plasmid DNA was significantly low, depending on the amount of PEI introduced. It is concluded that the CS/PEI nanoparticle was a promising carrier for gene delivery of MSCs. 223 0920-5063 2 JOURNAL OF BIOMATERIALS SCIENCE-POLYMER EDITION 205 21 VSP BV Nanoparticles Gene Delivery Efficacy of Polyethyleneimine-Introduced Chitosan Shell/Poly(methyl Methacrylate) Core Nanoparticles for Rat Mesenchymal Stem Cells 2433/151721 Hashimoto, Akira 2011/12/13 This study reinvestigated the synthesis of cellulose in vitro with a well-known cellulose-producing bacterium, Gluconacetobacter xylinus. Alkylmaltoside detergents, which are more frequently used in recent structural biological researches, are uniquely used in this study to solubilize cellulose-synthesizing activity from the cell membrane of G. xylinus. Activity comparable to that previously reported is obtained, while the synthesized cellulose is crystallized into a non-native polymorph of cellulose (cellulose II) as well as the previous studies. In spite of this failure to recover the native activity to synthesize cellulose I microfibril in vitro, the product is a polymer with a degree of polymerization greater than 45 as determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). It was thus concluded that the established protocol can solubilize cellulose-synthesizing activity of G. xylinus with polymerizing activity. 2768 0008-6215 17 Carbohydrate research 2760 346 Elsevier Ltd.

A high-strength spinal interbody fusion device was manufactured from porous titanium metal. A bioactive surface was produced by simple chemical and thermal treatment. Five patients with unstable lumbar spine disease were treated surgically using this device in a clinical trial approved by our Ethics Review Committee and the University Hospital Medical Information Network. Clinical and radiological results were reported at the minimum follow-up period of 1 year. The optimal mechanical strength and interconnected structure of the porous titanium metal were adjusted for the device. The whole surface of porous titanium metal was treated uniformly and its bioactive ability was confirmed before clinical use. Successful bony union was achieved in all cases within 6 months without the need for autologous iliac crest bone grafting. Two specific findings including an anchoring effect and gap filling were evident radiologically. All clinical parameters improved significantly after the operation and no adverse effects were encountered during the follow-up period. Although a larger and longer-term follow-up clinical study is mandatory to reach any firm conclusions, the study results show that this porous bioactive titanium metal is promising material for a spinal fusion device. 1495 0940-6719 9 European spine journal 1486 20 Springer-Verlag Porous titanium metal A novel synthetic material for spinal fusion: a prospective clinical trial of porous bioactive titanium metal for lumbar interbody fusion 2433/154577 Katano, Masahiro 2012/01/30 The transient receptor potential M2 channel (TRPM2) is the Ca(2+)-permeable cation channel controlled by cellular redox status via β-NAD(+) and ADP-ribose (ADPR). TRPM2 activity has been reported to underlie susceptibility to cell death and biological processes such as inflammatory cell migration and insulin secretion. However, little is known about the intracellular mechanisms that regulate oxidative stress-induced cell death via TRPM2. We report here a molecular and functional interaction between the TRPM2 channel and EF-hand motif-containing protein EFHC1, whose mutation causes juvenile myoclonic epilepsy (JME) via mechanisms including neuronal apoptosis. In situ hybridization analysis demonstrates TRPM2 and EFHC1 are coexpressed in hippocampal neurons and ventricle cells, while immunoprecipitation analysis demonstrates physical interaction of the N- and C-terminal cytoplasmic regions of TRPM2 with the EFHC1 protein. Coexpression of EFHC1 significantly potentiates hydrogen peroxide (H(2)O(2))- and ADPR-induced Ca(2+) responses and cationic currents via recombinant TRPM2 in HEK293 cells. Furthermore, EFHC1 enhances TRPM2-conferred susceptibility of HEK293 cells to H(2)O(2)-induced cell death, which is reversed by JME mutations. These results reveal a positive regulatory action of EFHC1 on TRPM2 activity, suggesting that TRPM2 contributes to the expression of JME phenotypes by mediating disruptive effects of JME mutations of EFHC1 on biological processes including cell death. 185 0143-4160 2 Cell calcium 179 51 Elsevier Ltd.

Electronic, ionic and gaseous transports with electrochemical reaction are considered in the porous anode. A sub-grid scale (SGS) model is newly developed and effectively used to consider the structural information whose characteristic scale is smaller than calculation grid size. The proposed SGS models are designed to keep the quality of the structural information which is inevitably lost by resampling process in grid generation. Through comparisons between the simulation results and the experimental data, it was found that the SGS model can either improve the simulation accuracy under a given calculation grid system or reduce computational load for the same degree of simulation accuracy.

The interaction of the counteranions with H+ and Pd as well as Zn2+ was suggested as an important factor for the chemical ZnO deposition, and it was found that only NO3- can raise the pH of a DMAB solution without DO, affording the continuous ZnO growth. Dissolved oxygen accelerated the ZnO nucleation process on the Pd and had less influence comparable to NO3- on the subsequent growth on the ZnO surface. The ZnO films deposited from Zn(NO3)2–DMAB solutions bubbled with O2, air, or Ar gas were characterized with an X-ray diffractometer, field emission scanning electron microscope, UV-visible spectrophotometer, and Hall coefficient analyzer. The Ar-bubbled solution gave superior ZnO films in terms of crystallinity, growth orientation, surface morphology, and electrical conductivity due to the relatively moderate crystal nucleation compared to in the presence of DO.

Mice lacking the membrane-anchored metalloproteinase regulator Reck die in utero around embryonic day 10.5 with halted vascular development; however, the mechanisms by which this phenotype arises remain unclear. RESULTS: We found that Reck is abundantly expressed in the cells associated with blood vessels undergoing angiogenesis or remodelling in the uteri of pregnant female mice. Some of the Reck-positive vessels show morphological features consistent with non-sprouting angiogenesis. Treatment with a vector expressing a small hairpin RNA against Reck severely disrupts the formation of blood vessels with a compact, round lumen. Similar defects were found in the vasculature of Reck-deficient or Reck conditional knockout embryos. CONCLUSIONS: Our findings implicate Reck in vascular remodeling, possibly through non-sprouting angiogenesis, in both maternal and embyonic tissues. 1471-213X BMC developmental biology 10 BioMed Central Ltd.

In spite of an extensive literature servey, sufficient information of the difference between them could not be obtained.

Single nanotube spectroscopy revealed triple the PL intensity enhancement for carbon nanotubes on rough Au surfaces as on fused silica surfaces. The PL enhancement depends on the excitation wavelength and distance between the carbon nanotubes and the Au surface. The degree of PL enhancement is determined by the electric field enhancement from the localized surface plasmon and the energy transfer from the carbon nanotube to the metal surface. 0003-6951 6 Applied Physics Letters 97 American Institute of Physics Plasmon-assisted photoluminescence enhancement of single-walled carbon nanotubes on metal surfaces 2433/119072 岡村, 武彦 1987/02/27 A case of renal cell carcinoma accompanied by a giant cyst in a 69-year-old male patient is reported. The patient consulted a physician in our Hospital for bellyache on the left abdomen. Because giant cyst in the left kidney and intracystic hemorrhage were suspected by computed tomography diagnosis, the patient was transferred to the Department of Urology, As a tumor-like mass was detected in the cyst by ultrasound echo diagnosis, transperitoneal extirpation of the left kidney was conducted on May 8, 1985. At operation, a giant unilocular cyst covered with hypertrophic fibrous capsule including much coagula was observed. The inner wall of the cyst was covered with many deeply yellow torous lesions of sizes ranging from those of a wheat grain to thumb. Histologically, the lesions consisted of a cell group supposedly of histiocyte origin accompanied by cellular infiltration of lymph cells, and xanthoma was deeply suspected. However, as it was difficult to distinguish from the clear cell subtype of renal cell carcinoma, examination by an electron microscope was conducted and the final diagnosis of renal cell carcinoma was made. The post-operative course of the patient was good and no recurrence or cancer metastasis was observed as of January, 1986. 413 0018-1994 3 泌尿器科紀要 409 33 泌尿器科紀要刊行会 Renalcyst A case of renal cell carcinoma with the complication of a giant cyst difficult to distinguish from xanthoma 巨大腎嚢胞に合併し,黄色腫との鑑別困難であった腎癌の1例 2433/139440 Tange, Ryu 2010/12/30 We have developed novel photovoltaic systems composed of the fullerene derivative (6,6)-phenyl C61 butyric acid methyl ester as electron acceptor with a second functional organic molecule, in this case bacteriochlorophyll c, as the light-harvesting and photosensitizing part. It was found that heat treatment of a thin film of bacteriochlorophyll c altered the morphological states of the aggregates and conductivity of the thin film could be regulated through the annealing process. Blended fullerene derivative and bacteriochlorophyll c thin films were fabricated on the surface of an indium-tin oxide/poly(ethylene dioxythiophene) doped with polystyrene sulfonic acid substrate layer and their photovoltaic properties were characterized and evaluated. Formation of fullerene-coordinated bacteriochlorophyll c complex was confirmed by changes in the visible absorption spectra and by FTIR. Such complexation promoted generation of photocurrent in the region of the Qy band and the current density of the thin film increased. A maximum incident photon-to-current conversion efficiency of 5.1% was attained at 745 nm. 310 0884-2914 02 Journal of Materials Research 306 26 Cambridge University Press biomimetic (assembly) Application of self-assembling photosynthetic dye for organic photovoltaics 2433/77789 Ogino, Yoshiko 2006/05/23 Kyoto University せん断流動場における高分子の結晶化 Crystallization of Polymers under Shear Flow 2433/77891 Murata, Sumihiko 2001/03/23 Kyoto University フラクタルモデルを用いた岩盤不連続面の力学特性および水理学特性評価に関する研究 Characterization of the mechanical and hydrological properties of a rock joint by using a fractal model 2433/144633 TAN SHAU HWAI, AILEEN 2008/10/30 Diversity of the family Fungiidae was investigated in Malaysian waters during an expedition in 2004. From the samples collected on 18 reef locations around Malaysian waters, only 12 locations contained fungiid corals. From the locations that have fungiid corals, 11 species from five genera were recorded. They are Fungia (Ctenactis) echinata, Fungia (Ctenactis) simplex, Fungia (Danafungia scruposa, Fungia (Danafungia) danai, Fungia (Fungia) fungites, Fungia (Pleuractis) paumotensis, Fungia (Pleuractis) scutaria, Halomitra pileus, Sandalolitha robusta, Herpolitha limax and Polyphyllia talpina. The diversity of the fungiid corals at Hempasan Dang Ajar and Terumbu Peninjau far outweighs all other sites with six different species at each location. Other locations have three species on average. Out of 11 species of Fungiidae coral, Sandalolitha robusta and Herpolitha limax are the most commonly found species. They are found on seven sampling locations each. The rarest species are Fungia simplex, Fungia scruposa and Fungia paumotensis which can be found at only one sampling location each. Other available species could be found at three locations on average. This study has reported higher number of fungiid species compared to previous studies done in Peninsular Malaysia but similar with the study done in Singapore. 24 0389-6609 Publications of the Seto Marine Biological Laboratory.

This membrane was fabricated by transferring a TNA embedded in a titanium foil onto a sputtered 10-μm-thick palladium film. Alcohols are reformed photocatalytically and concurrently generated hydrogen is purified through the Pd layer. H2 with a purity of more than 99% was obtained from liquid alcohols under ultraviolet illumination onto the membrane. Thus, we demonstrated the integration of photocatalytic hydrogen production and purification within a single membrane. 0003-6951 12 Applied Physics Letters 99 American Institute of Physics catalysis High-purity hydrogen generation by ultraviolet illumination with the membrane composed of titanium dioxide nanotube array and Pd layer 2433/151979 Mary Donnabelle Lirio Balela 2011/09/26 Kyoto University ナノ金属材料 無電解電析による金属コバルトナノ粒子およびナノワイヤーの合成 Syntheses of Metallic Cobalt Nanoparticles and Nanowires by Electroless Deposition 2433/75573 Suito, Eiji 1956/12/01 315 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 307 34 Institute for Chemical Research, Kyoto University Electron Microscopic Study on Some Viscous Colloidal Solutions 2433/152322 Namura, Kyoko 2011/09/15 We have investigated the heat generation from gold nanoparticles resulting from their local plasma resonance. We have demonstrated the self-assembly of Au nanoparticle arrays/dielectric layer/Ag mirror sandwiches, i.e., a local plasmon resonator, using a dynamic oblique deposition technique. The thicknesses of the Au and dielectric layers were changed combinatorially on a single substrate. As a result, local plasmon resonator chips were successfully fabricated. Because of strong interference, their optical absorption can be controlled between 0.0% and 97% in the near-IR region, depending on the thickness of the dielectric layer. We evaluated the heat generation from Au nanoparticles by measuring the temperature of water with which a cell prepared on a chip is filled under laser illumination. The change in the water temperature is proportional to the optical absorption of the local plasmon resonator chips. This suggests that the photothermal conversion efficiency can be controlled by interference. These features make the application of the local plasmon resonator to nanoheaters, which can spatiotemporally control heat generation, suitable. 3535 0146-9592 18 Optics Letters 3533 http://www.opticsinfobase.org/ol/abstract.cfm?uri=ol-36-18-3533 36 Optical Society of America Heat-generating property of a local plasmon resonator under illumination 2433/152545 Toyohara, Haruhiko 2011/12/30 To validate the involvement of meiobenthos in cellulose breakdown in wetlands, meiobenthos were collected from sediments of Lake Furen and the Biwase River in Hokkaido Prefecture, the Kako River in Hyogo Prefecture, and the Chinai River in Shiga Prefecture. Cellulase activities of the meiobenthos were measured by cellulose zymographic analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) gels containing 0.5% carboxymethyl cellulose. The results showed that most of the Turbellaria, Nematoda, Harpacticoida, and Oligochaeta species exhibited cellulase activity. The molecular sizes of the cellulase-active bands of the sediments in Lake Furen, the Biwase River, and the Chinai River coincided with those of meiobenthos. The findings suggest that meiobenthos might play a major function in cellulose breakdown in these wetlands. This paper is the first to report cellulase activity in meiobenthos and that they are possibly involved in the breakdown of cellulose in wetlands. 137 0919-9268 1 Fisheries Science 133 78 Springer Verlag Cellulase Cellulase activity in meiobenthos in wetlands 2433/152514 Hamidreza Jafarian 2012/01/23 Kyoto University martensitic Fe-Ni-C合金における超微細粒準安定オーステナイトからのマルテンサイト変態 Martensitic Transformation from Ultrafine Grained Meta-stable Austenite in Fe-Ni-C Alloy 2433/68015 KONDO, Takaki 1986/01/30 Abundance of zooplankters was examined by net collection on a rocky shore at the northwestern end of Lake Tanganyika in February 1980 and August 1983. Zooplankters found were Mesocyclops leuckarti, Diaptomus simplex, Ergasiloides sp. (Copepoda), Ostracoda, shrimps, Asplanchna sp. (Rotifera) and Vorticella sp. (Protozoa). Species composition of zooplankton was rather simple and characterized by the dominance of Copepoda, especially nauplii and cyclopoid copepodites. Nauplii smaller than 0.2 mm in body length were more abundant in August than in February, which suggests that the reproductive activity of copepods changes seasonally. The density of zooplankters tended to be lower at the bottom in the daytime, probably because of the predation by fish. The density of copepods changed with the time of day; low at noon and high in the afternoon. Such diel fluctuation in the abundance of copepods may influence the feeding activity of fish. 23 0285-1601 African Study Monographs 17 6 The Research Committee for African Area Studies, Kyoto University Abundance of Zooplankters on a Rocky Shore of Lake Tanganyika: A Preliminary Report 2433/153285 Okuda, Hiroshi 2012/01/30 Anomalous dispersion at the Si K absorption edge has been used to control the reflection from the interface between a film and an Si substrate, which otherwise complicates the nanostructure analysis of such a film, particularly for the soft-matter case, in grazing-incidence small-angle scattering. Such a reflectionless condition has been chosen for a triblock copolymer thin film, and two-dimensional grazing-incidence small-angle scattering patterns were obtained without the effect of the reflection. The present approach is useful for analysing nanostructures without introducing complicated corrections arising from the reflection. 121 0021-8898 1 Journal of Applied Crystallography 119 45 International Union of Crystallography grazing-incidence small-angle X-ray scattering Contrast matching of an Si substrate with polymer films by anomalous dispersion at the Si 2433/74708 Usui, Hiroaki 1988/03/23 Kyoto University クラスターイオンビーム技術 : 蒸気化固体物質によるクラスタービームの生成と、その薄膜形成への応用 IONIZED CLUSTER BEAM TECHNIQUES: Formation of Cluster Beams by Vaporized Solid Materials and Their Applications to Film Depositions 2433/87310 Tanida, Shinji 2009/10/30 N-channel operation of thin-film transistors based on 1,4,5,8-naphthalene tetracarboxylic dianhydride (NTCDA) with a 9-nm-thick poly(methyl methacrylate) (PMMA) gate buffer layer was examined. The uniform coverage of the ultrathin PMMA layer on an SiO2 gate insulator, verified by X-ray reflectivity measurement, caused the increase of electron field-effect mobility because of the suppression of electron traps existing on the SiO2 surface. In addition, air stability for n-channel operation of the NTCDA transistor was also improved by the PMMA layer which possibly prevented the adsorption of ambient water molecules onto the SiO2 surface. 574 00406090 2 Thin Solid Films 571 518 Elsevier Air stability N-channel thin-film transistors based on 1,4,5,8-naphthalene tetracarboxylic dianhydride with ultrathin polymer gate buffer layer 2433/75949 Horio, Masao 1963/03/30 9 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 1 41 Institute for Chemical Research, Kyoto University Effect of Gamma Irradiation upon Wool Fibers (Special Issue on Physical, Chemical and Biological Effects of Gamma Radiation, IV) 2433/154940 2010/10/30 76 1342-0321 ICR annual report 71 18 Institute for Chemical Research, Kyoto University Activities of Joint Usage/Research Center 2433/76012 Sakurada, Ichiro 1964/06/30 152 0023-6071 2-3 Bulletin of the Institute for Chemical Research, Kyoto University 145 42 Institute for Chemical Research, Kyoto University Estimation of Particle Size of Synthetic Latices by Turbidity Measurements (Special Issue on Polymer Chemistry, I) 2433/87356 Matsuda, Kazunari 2008/04/29 We studied the mechanism of the photoluminescence (PL) enhancement and quenching of single CdSe/ZnS nanocrystals on rough Au surfaces. Single nanocrystal spectroscopy revealed that the PL enhancement depends strongly on the excitation wavelength and liner-polarization angle due to the localized plasmon excitation and is also sensitive to the nanocrystal size. The polarization- and size-dependent PL enhancement and quenching are determined by the balance between the resonant energy transfer from the nanocrystal to the Au surface and the electric field enhancement. 0003-6951 21 Applied Physics Letters 92 American Institute of Physics Photoluminescence enhancement and quenching of single CdSe/ZnS nanocrystals on metal surfaces dominated by plasmon resonant energy transfer 2433/155991 KAWAKATSU, Masaharu 1972/10/21 0452-9987 1 Contributions from the Biological Laboratory, Kyoto University 1 24 京都大学教養部生物学教室 Report on Freshwater Planarians from Malaya and Thailand 2433/76077 Takada, Toshio 1966/02/28 415 0023-6071 4-5 Bulletin of the Institute for Chemical Research, Kyoto University 406 43 Institute for Chemical Research, Kyoto University Magnetic Properties of α-Fe₂O₃ Fine Particles 2433/65726 1996/02/28 1342-0321 ICR annual report 2 Institute for Chemical Research, Kyoto University ICR ANNUAL REPORT 1995(Volume 2) 2433/156523 Ueda, Motoki 2011/02/27 Two types of peptide nanotubes, one is prepared from an amphiphilic peptide having a right-handed helix segment and the other from that having a left-handed helix segment, are shown to transform the morphology into a vesicle by membrane fusion due to stereo-complex formation between these helical segments. 3206 1359-7345 11 Chemical communications 3204 47 Royal Society of Chemistry Transformation of peptide nanotubes into a vesicle via fusion driven by stereo-complex formation. 2433/76196 Tsuji, Waichiro 1967/07/20 121 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 112 45 Institute for Chemical Research, Kyoto University The Crystalline Structure of Ethylene-Butene-1 Copolymers (Special Issue on Polymer Chemistry, IV) 2433/157130 Hiroi, Junya 1999/03/23 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University 硬骨魚類の発育初期における浸透圧調節機構 Osmo-and Iono-Regulation during Early Developmental Stages of Teleosts 2433/87365 Ishizumi, Atsushi 2005/05/30 We have studied photoluminescence (PL) properties of Eu-doped ZnO (ZnO:Eu) nanorods fabricated by a microemulsion method. The ZnO:Eu nanorods have a hexagonal crystal structure and exhibit a sharp luminescence due to the intra-4f transitions of Eu3+ ions. The excitation energy and temperature dependence of the PL intensity show that the Eu3+-related PL efficiency is determined by the energy relaxation process of excited Eu3+ ions, rather than by the energy transfer process from ZnO nanorods to Eu3+ ions. The energy transfer and luminescence processes in ZnO:Eu nanorods are discussed. 0003-6951 25 Applied Physics Letters 86 American Institute of Physics Structural and luminescence properties of Eu-doped ZnO nanorods fabricated by a microemulsion method.

The similar release profile of SDF-1 and BMP-2 from the hydrogels was observed with or without the combination of BMP-2 and SDF-1, respectively. An enhanced bone regeneration by the hydrogels incorporating combined SDF-1 and BMP-2 was observed. In addition, the implantation of hydrogels incorporating combined SDF-1 and BMP-2 enhanced the expression level of CXC chemokine cell-surface receptor-4 (Cxcr4), Runt-related factor-2 (Runx2), and Osteocalcin genes. The experiments with green fluorescent protein (GFP)-positive Chimeric mice revealed that the recruitment of bone marrow-derived cells was promoted and a vascular-like structure together with strong accumulation of CD31- and CD34-positive cells was observed at the site of hydrogels incorporating combined SDF-1 and BMP-2 implanted. In addition, a large fraction of CD29- and CD44-positive non-hematopoietic cells was detected. It is concluded that the combined release of SDF-1 and BMP-2 enhanced the recruitment of osteogenic cells and angiogenesis, resulting in the synergistic effect on bone regeneration. 著者版のタイトルと出版社版のタイトルに差異あり 2811 0142-9612 11 Biomaterials 2797 32 Elsevier Ltd.

Single PL peak from isolated individual SWNT with a chiral index of (6, 5) showed a linear increase and saturation behavior of the PL intensity. Unusual PL intensity fluctuation in the temporal evolutions of the PL intensity, referred to as PL intermittency, was seen with some SWNTs, while the PL intensity with most SWNTs remained at a constant amplitude. The mechanism of the PL intermittency was discussed. 0003-6951 12 Applied Physics Letters 86 American Institute of Physics Photoluminescence intermittency in an individual single-walled carbon nanotube at room temperature 2433/87367 Nihonyanagi, Satoshi 2004/11/29 We have studied photoluminescence (PL) from the condensed phase in silicon-on-insulator samples with different Si layer thickness from 50 to 340 nm. Two major PL bands are observed at low temperatures, originating from free excitons (FE) and electron–hole droplets (EHD). It is found that with an increase of the excitation intensity the EHD PL shows a linear increase in the 50-nm-thick layer while a superlinear increase in the 340-nm-thick layer. The intensity ratio of the EHD PL to the FE PL in the 50-nm-thick layer is much larger than that in the 340-nm-thick layer under the same experimental conditions. The luminescence from the EHD is enhanced in thin Si nanolayers. These results suggest that highly dense electrons and holes are formed in the Si nanolayer and the interfaces act as the nucleation center of the EHD. 0003-6951 23 Applied Physics Letters 85 American Institute of Physics Enhanced luminescence from electron-hole droplets in silicon nanolayers 2433/86182 Khatri, Om P. 2009/08/30 Vacuum ultraviolet (VUV, λ = 172 nm) patterning of alkyl monolayer on silicon surface has been demonstrated with emphasis on the diffusion of VUV induced oxygen-derived active species, which are accountable for the pattern broadening. The VUV photons photo-dissociates the atmospheric oxygen and water molecules into the oxygen-derived active species (oxidants). These oxidants photo-oxidize the hexadecyl (HD) monolayer in VUV irradiated regions (Khatri et al., Langmuir. 24 (2008) 12077), as well as the little concentration of oxidants diffuses towards the masked areas. In this study, we performed VUV patterning at a vacuum pressure of 10 Pa to track the diffusion pathways for the oxidants with help of gold nanoparticles (AuNPs; = 10 nm) immobilization. At VUV irradiated sites AuNPs are found as uniformly distributed, but adjacent to the pattern boundary we observed quasi-linear arrays of AuNPs, which are determined by diffusion pathways of the oxidants. The diffusion of oxidants plays vital role in pattern broadening. The site selective anchoring of AuNPs demonstrates the utility of VUV photons for the construction of functional materials with microstructural architecture. 9821 01694332 24 Applied Surface Science 9817 255 Elsevier Gold nanoparticles Probing the diffusion of vacuum ultraviolet (λ = 172 nm) induced oxidants by nanoparticles immobilization 2433/84585 Takahashi, Yasushi 2008/06/16 We investigated the optical characteristics of higher-order resonant modes for a heterostructure nanocavity formed in a two-dimensional photonic-crystal silicon slab.

The cavities show a linear dependence on these parameters, a 1-nm increase of lattice constant or air-hole size leading to 4.2-nm increase or 1.56-nm decrease of the resonant wavelength, respectively. These experimental results are in good agreement with the finite-difference time-domain calculations and have a small standard deviation of wavelength (~1 nm) between samples on a single chip. These results will stimulate development in areas such as ultrasmall and multichannel filters, sensors, and switches. 534 1041-1135 5-8 IEEE PHOTONICS TECHNOLOGY LETTERS 532 20 IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC nanocavity Resonant-wavelength control of nanocavities by nanometer-scaled adjustment of two-dimensional photonic crystal slab structures 2433/84574 Horita, Masahiro 2008/08/25 Nonpolar AlN layers were grown on 4H-SiC (1[overline 1]00) substrates by plasma-assisted molecular-beam epitaxy. By using SiC substrates with well-formed step-and-terrace structures, stable layer-by-layer growth of 4H-AlN (1[overline 1]00) can be realized. The layer-by-layer growth is confirmed by observations of anisotropic two-dimensional AlN islands on the grown surface as well as persistent reflection high-energy electron diffraction intensity oscillations.

The coated nanofiber sheets exhibited high transparency regardless of the wide distribution of refractive indexes of the coated resins, and the loss of transparency compared with the theoretical values was less than 2.5%. The low coefficient of thermal expansion of the nanofiber sheets (8.5 ppm/K) was maintained after the coating. The continuous coating of functional transparent materials on the nanofiber sheets is a promising approach toward accomplishing a simple roll-to-roll manufacturing process. 00036951 23 Applied Physics Letters 94 American Institute of Physics Optically transparent nanofiber sheets by deposition of transparent materials: A concept for a roll-to-roll processing 2433/65217 2000/02/28 84 1342-0321 ICR annual report 79 6 Institute for Chemical Research, Kyoto University SEMINARS 2433/53020 SATO, Akira 1968/02/28 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 16 0049-7916 木材研究 : 京都大學木材研究所報告 9 43 京都大學木材研究所 木材フェノール性化合物に関する研究(第3報) : Haplormosia材からサクラネチンの同定 Studies on Wood Phenolics (III) : Identification of Sakuranetin from Wood of Haplormosia monophylla HARMS (Leguminosae) 2433/45691 Hase, Masahiko 2006/10/06 Excitable media show changes in their basic characteristics that reflect temporal changes in the environment. In the photosensitive Belousov-Zhabotinsky (BZ) reaction, excitability is decreased by illumination. We found that a traveling pulse failed to propagate when a certain level of light intensity was switched on abruptly, but the pulse continued propagating when the light intensity reached the same level gradually. We investigated the mechanism of adaptation of pulse propagation to the change in light intensity using two mathematical models, the Oregonator model (a specific model for the photosensitive BZ reaction), and the FitzHugh-Nagumo model (a generic model for excitable media). The appearance of a characteristic such as adaptation is shown to be a general feature for a traveling pulse in excitable media. © 2007 The American Physical Society. 1539-3755 4 Physical Review E http://link.aps.org/abstract/PRE/v74/e046301 74 American Physical Society drops Rhythmic motion of a droplet under a dc electric field 2433/53382 ITOH, Takao 1975/03/31 Freeze etching technique was applied for investigating cell wall organization of parenchyma cells in the cortex. This technique gave highly oriented microfibrils in any lamellae and did very good insight into three dimensional relationship among cytoplasm, plasmalemma and cell wall. The technique can also give information of the orientation of microfibrils inherent to respective lamella which makes wall by piling up in a complex manner. Hence, freeze etching technique seems more reliable for the study of natural states of cell wall organization than the classical direct shadow casting technique and more recent replicating, followed by shadow casting techniques. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 32 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 20 58 Wood Research Institute, Kyoto University Application of Freeze Etching Technique for Investigating Cell Wall Organization of Parenchyma Cells in Higher Plants 2433/76686 1977/03/25 518 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 472 54 Institute for Chemical Research, Kyoto University Abstracts of the Papers Published by the Staff Members of the Institute from July, 1975 to June, 1976 (Special Issue on the Commemoration of the Fiftieth Anniversary) 2433/76701 1977/03/25 401 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 396 54 Institute for Chemical Research, Kyoto University Laboratory of Ceramic Chemistry (Special Issue on the Commemoration of the Fiftieth Anniversary) 2433/76704 1977/03/25 380 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 374 54 Institute for Chemical Research, Kyoto University Laboratory of Surface Chemistry (Special Issue on the Commemoration of the Fiftieth Anniversary) 2433/76714 Kurakado, Masahiko 1977/03/31 45 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 38 55 Institute for Chemical Research, Kyoto University Superconducting Transition Temperature of Technetium and Lead 2433/76725 Nogami, Kazuo 1977/08/31 236 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 227 55 Institute for Chemical Research, Kyoto University An Optical Study on Shear-Induced Crystallization of Polymers (Commemoration Issue Dedicated to Professor Keinosuke Kobayashi on the Occasion of His Retirement) 2433/68743 Miyafuji, Hisashi 2000/11/24 Kyoto University ゾル-ゲル法による難燃性無機質複合化木材の創製 Wood-Inorganic Composites with Fire-Resistance as Prepared by the Sol-Gel Process 2433/49162 Araki, Sumiko 2005/12/30 It is generally accepted that linear polymers are larger, such as with regard to the end-to-end distance and gyration radius, than the corresponding circular polymers.

DON) and KUROMATSU (Pinus Thunbergii L.) with its dormant and active state were compared on the ultra-structural level after glutaraldehyde-osmium tetroxide fxation. The characteristics observed in the dormant cambium are as follows. 1. The organelles are densely and uniformly distributed throughout cytoplasm. 2. Comparatively many vacuoles are present and they are small. 3. Vesiculated smooth ER are rich, although rough-type ones are sometimes observed. 4. Amoeboid type plastids.can scarcely be seen. 5. Reserve substances such as starch granules and lipid droplets are comparatively abundant. In contrast to the dormant cambium the active one is characterized as follows. 1. Cytoplasm is localized at the periphery of cambial cells. 2. Cytoplasm is occupied by a large vacuole. 3. A number of rough ER are present. 4. Amoeboid type plastids are frequently seen. 5. Starch granules and lipid droplets are few. In addition, cytological differences between SUGI and KUROMATSU are as follows. The cambium of SUGI is characterized by the presence of intralamellar inclusion of some plastids in the dormant state and of phytoferritin of plastids through both states, whereas the cambium of KUROMATSU is characterized by the presence of numerous reserve substances, especially lipid droplets, in the dormant state. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 45 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 33 51 Wood Research Institute, Kyoto University On the Ultrastructure of Dormant and Active Cambium of Conifers 2433/76840 Shigematsu, Toshihiko 1979/10/15 317 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 310 57 Institute for Chemical Research, Kyoto University Formation of Metastable Phase in Vapor-Deposited FeSb Films 2433/76938 Kobayashi, Yasuhiro 1981/09/01 255 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 248 59 Institute for Chemical Research, Kyoto University Chemical Transport Reactio n of Niobium Oxides (Commemoration Issue Dedicated to Professor Megumi Tashiro on the Occation of his Retirement) 2433/49168 Hibino, Kumiko 2006/07/30 The protective effects of alkali metal ions (Li+, Na+, K+, Rb+ and Cs+) against spermidine-induced DNA compaction were studied using single-molecule observations. We found that all alkali metal salts prevent DNA compaction, where Na+ more strongly prevented DNA compaction than other alkali metal ions.

The test blocks were connected by a rope and submerged at 0.3, 0.8 and 1.3 m below the water surface, and at regular intervals of 1 m from 2 m to the bottom level (about 23 m). The blocks were removed and replaced every month for examining monthly settlement of shipworms on the surfaces of the blocks. The heavier settlement of shipworms was generally observed in deeper regions, particularly at the bottom. This tendency was prominent in the months when the furious shipworm settlement was noticed. The patterns of monthly vertical settlement of shipworms on wood surfaces were divided into the following 4 types: (1) The intensity of settlement of shipworms increases proportionally with water depth so that the maximum settlement is recorded at the deepest level (September, 1975 and August, 1976). (2) The heaviest settlement is observed at the deepest level with the second peak at about 10 m depth (July and October, 1976). (3) The heaviest settlement is recorded at approximately 10 m depth; the extent of settlement increases in proportion to water depth down to 10 m level and then decreases adversely, but rises again at depths between 20 m and 23 m (August and October, 1975; September, 1976). (4) The settlement occurs very slightly and relatively evenly along the water column (June, July and December, 1975; June, November and December, 1976). The effect of light intensity and water temperature gradient with water depths would partly account for the different patterns of monthly vertical settlement of shipworms. And the active vertical locomotion of shipworms might help shipworms concentrate at deeper levels. The results suggest that the sunken logs at the bottom are the important reproductive sources of shipworms. It is therefore helpful to remove not only riddled floating wood and logs but also sunken logs for reducing shipworm attack in the sea water log storage areas. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 8 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 1 64 Wood Research Institute, Kyoto University Studies on the Shipworms III : Pattern of Vertical Settlement of Shipworms 2433/53360 TSUNODA, Kunio 1979/03/24 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 53 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 11 65 Wood Research Institute, Kyoto University Ecological Studies of Shipworm Attack on Wood in the Sea Water Log Storage Site 2433/77000 Kokubo, Tadashi 1982/10/15 268 0023-6071 3-4 Bulletin of the Institute for Chemical Research, Kyoto University 260 60 Institute for Chemical Research, Kyoto University Apatite- and Wollastonite-Containg Glass-Ceramics for Prosthetic Application 2433/53329 YATA, Shigeki 1983/03/25 The potential and limitations of the SEM-EDXA technique for determination of the metal concentration and its distribution in the preservative-treated wood were investigated. Operating conditions such as the accelerating voltage (20 keV), the working distance (15mm), the illuminating current (200 μμA.) and the distance of the X-ray detector from the specimen were held constant throughout the entire study. Results obtained were as follows. (1) The smallest size which it was practible to analyse in the bulk specimen was in the range of 3.5-4.5 μm in diameter. Hence the different cell wall layers were not analysed as separate entities in the point analysis. (2) Acquisition time of X-rays at one point on the cell wall at most should be restricted within 200 seconds for the prevention of the heat-damage of the specimen by electron bombardment. (3) Tilting angle of the specimen affected greatly the X-ray emission. Hence, for quantitative analysis, the comparison of X-ray intensities should be restricted within the portion which take the same tilting angle. (4) The X-ray intensity increased linearly in proportion to the metal concentration in the cell wall although there was a considerable variation in analysis. (5) Minimum detection limit of Cr, Cu and Zn in the cell wall was about 0.1 w/w percent in every case. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 79 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 71 69 Wood Research Institute, Kyoto University Application of SEM-EDXA Technique to the Study of Metal Distribution in Preservative-Treated Wood 2433/53330 YATA, Shigeki 1983/03/25 Distribution and concentration of salts in the wood of three species, all treated with aqueous salt solutions of Cr, Cu or Zn to the longitudinal direction of the airdried wood by capillary pressure, were determined using the SEM-EDXA technique. In the line analysis the X-ray intensities varied widely with positions analysed since the rough surface structure of wood caused incomplete detection of X-rays. However, when the scanning line was put along the intercellular layer between the regularly oriented radial files of tracheids, a smooth curve was obtained. In this case overall trends of curves obtained were coincident with the results of the point analysis. The line-scan curve took a peak on the initiatively penetrated cell and gradually lowered at its surrounding region. Deposition of the salt could be seen frequently on the inner surface of the cell wall of the penetrated cell. From the gentle gradient of metal concentration in the surrounding region it was shown that the metal-distribution in this region was attributed to the ionic diffusion through the cell wall, not to the lateral liquid-flow through the lumen-pit system. The smooth curves were drawn across the different cell types, the multiseriate rays and across the annual ring boundary. Hence, it was concluded that the ionic diffusion through the cell wall proceeded uniformly from the penetrated cells to their surrounding regions. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 88 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 80 69 Wood Research Institute, Kyoto University Distribution of Metal Elements in Wood Impregnated with Aqueous Solutions of Metal Salts as Determined by SEM-EDXA 2433/77124 Odani, Hisashi 1986/01/20 339 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 332 63 Institute for Chemical Research, Kyoto University Permeation of Gases in Poly(2-vinylpyridine)-Block-Polyisoprene 2433/53321 SUMIYA, Kazuo 1984/02/29 Nine wood quality indicators are compared with three groups of growth rates and three types of load-deflection curves in bending on 36 cultivars of juvenile Japanese cedar (Cryptomeria japonica D. Don). The fast-grown trees have shorter tracheids. In the load-deflection type having the large plastic region, tracheid length is shorter and fibrils lie more flatly and bending modulus of elasticity is lower on the same specific gravity as in other two load-deflection types. The trees in this type, therefore, seem to be more juvenile. Moreover, much proportion of the trees in this type belongs to the fast-grown group. Then, by all meams, the precise information of wood quality is necessary for the utilization of fast-grown cultivars. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 54 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 47 70 Wood Research Institute, Kyoto University Classified Characters of Wood Quality in the Junvenile Stage of Cultivars of Japanese Cedar 2433/77153 Terashima, Takahito 1986/12/06 276 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 267 64 Institute for Chemical Research, Kyoto University Surface Magnetism of Fe₃O₄ Thin Films (Commemoration Issue Dedicated to Professor Toshio TAKADA On the Occasion of His Retirement) 2433/77163 Nakayama, Noriaki 1986/12/06 180 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 170 64 Institute for Chemical Research, Kyoto University Structure of Fe-C Multilayered Films (Commemoration Issue Dedicated to Professor Toshio TAKADA On the Occasion of His Retirement) 2433/52125 LEE, Kaechoong 1986/08/31 A simple colorimetric method (color assay) was developed in order to evaluate the in vitro growth and survival of tumor cells in soft agar cultures. The assay detects the color changes in the medium caused by the accumulation of acidic metabolites at the end point of the culture. The chemosensitivity of two human tumor lines to various cytotoxic agents determined by the color assay correlated well with that determined by conventional colony count in bilayer soft agar cultures. The results suggested that the color assay can be used as a supportive method for the assessment of human tumor clonogenic assay (HTCA). この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 8 0009-3378 1/2 京都大学結核胸部疾患研究所紀要 1 19 京都大学結核胸部疾患研究所 A Simple Colorimetric Method for the Evaluation of Growth and Chemosensitivity of Tumor Cells in Soft Agar Culture 2433/77198 Kamata, Toshihide 1987/11/20 178 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 170 65 Institute for Chemical Research, Kyoto University Infrared ATR Spectra of Stearic Acid LB Films : Intensity Enhancement by Au Evaporation 2433/53971 2004/03/05 94 京都大学高等教育叢書 86 18 京都大学高等教育研究開発推進センター 記録 : Transcript・Comment 2 2433/77312 Asami, Koji 1989/12/15 224 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 217 67 Institute for Chemical Research, Kyoto University A Tubular-Epithelium Model Constructed from a Gelatin : Tube and Renal Epithelial Cells (MDCK) 2433/50209 Takahashi, K 2003/04/14 2478 0003-6951 15 APPLIED PHYSICS LETTERS 2476 http://link.aip.org/link/?apl/82/2476 82 AMER INST PHYSICS Characterization of porosity and dielectric constant of fluorocarbon porous films synthesized by using plasma-enhanced chemical vapor deposition and solvent process 2433/77387 Fujiwara, Shinsuke 1991/09/14 66 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 59 69 Institute for Chemical Research, Kyoto University Epitaxial Growth of Lead Chalcogenides on Tin Telluride (001) (Commemoration Issue Dedicated to Professor Ken-ichi Katayama On the Occasion of His Retirement) 2433/51691 YASUHIRA, Kimio 1966/11/29 Homologous immunity to Ehrlich ascites tumor was induced in C57BL mice after treatment with CF1 tumor or lymphoid cells. The induction of tumor immunity was considered to result from long-lasting antigenicity in CF1 cells of low virulence. A possibility of producing iso-immunity in CF1 mice was shown to exist after intravenous injection of large amount of CF1 tumor cells. Finally, a high sensitivity to the Ehrlich tumor was demonstrated in the lungs of young mice. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 84 2 Acta tuberculosea Japonica 78 16 Tuberculosis Research Institute, Kyoto University ACQUIRED IMMUNITY TO EHRLICH ASCITES TUMOR IN MICE AFTER TREATMENT WITH FRESH OR SONIZED TUMOR CELLS AT VARIOUS AGES 2433/51711 OKADA, Yoshio 1962/03/30 Comparative morphological study on the lung of the frog and newt was made leading to the following conclusions : 1) The lung of the newt is the simplest among vertebrates and seems to work not only as a respiratory organ but also as static organ. 2) In the lung of the frog, the "Vorbronchus", which serves as a passage for air, and the "primitive alveoli", in which gas exchange is performed, are fairly well differentiated. 3) In the mammalian lung, the "alveolar epithelial cell" is often assumed to be of mesenchymal orgin. However, in the amphibian lung, the "alveolar wall cell" resembles the "alveolar epithelial cell", and it may be ascertained that the "alveolar wall cell" is of epithelial origin. 4) Osmiophilic bodies are found in the "alveolar wall cell" and in the "alveolar epithelial cell" of the frog, but not in those of the newt. It is assumed that these bodies are highly developed organelles, and therefore, are not found in the newt which is one of the lowest forms of vertebrates with lungs. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 72 2 Acta tuberculosea Japonica 63 11 Tuberculosis Research Institute, Kyoto University COMPARATIVE MORPHOLOGY OF THE LUNG WITH SPECIAL REFERENCE TO THE ALVEOLAR EPITHELIAL CELLS : I.

An aqueous solution of urea was sprayed into a titanium tetraisopropoxide (TTIP) / hexane solution, inducing the rapid hydrolysis of TTIP at the interface between the droplets of urea solution and TTIP solution. The resultant hollow particles were converted to N-doped TiO2 with anatase crystal structure by heat treatment. The absorption ability of visible light was remarkably improved by nitrogen doping. The hollow N-doped TiO2 particles showed higher photocatalytic activity estimated by the decomposition of methylene blue (MB) compared to undoped TiO2 particles. 1160 18820743 1371 Journal of the Ceramic Society of Japan 1158 117 The Ceramic Socirty of Japan Hollow particle Fabrication of hollow N-doped TiO2 photocatalyst by sprayinduced hydrolysis 2433/109929 Shinagawa, Tsutomu 2008/10/30 The galvanic contact deposition of ZnO was carried out by immersing a conductive substrate short-circuited with a Zn rod into O2-saturated aqueous Zn(ClO4)2 solutions, and the deposition behaviors were investigated in comparison with that in Zn(NO3)2. The dissolution of the Zn rod in the Zn(ClO4)2 solutions supplied a continuous and almost constant current to the substrate, allowing the cathodic electrodeposition of ZnO without an external power and by-products. The morphology of the resulting ZnO depended on the Zn(ClO4)2 concentration. In contrast, a much smaller current was observed in the Zn(NO3)2 solution, and little ZnO was deposited.

Rb heterozygous mice generate Rb-deficient C cell adenomas that progress to adenocarcinomas following biallelic loss of N-ras. Here, we demonstrate that pRb inactivation induces aberrant expression of farnesyl diphosphate synthase, many prenyltransferases, and their upstream regulators sterol regulatory element-binding proteins (SREBPs) in an E2F-dependent manner, leading to enhanced isoprenylation and activation of N-Ras. Consequently, elevated N-Ras activity induces DNA damage response and p130-dependent cellular senescence in Rb-deficient cells. Furthermore, Rb heterozygous mice additionally lacking any of Ink4a, Arf, or Suv39h1 generated C cell adenocarcinomas, suggesting that cellular senescence antagonizes Rb-deficient carcinogenesis. がん抑制遺伝子不活性化によるがん化に対抗する生体の防御機構を解明. 京都大学プレスリリース. 2009-04-07. http://www.kyoto-u.ac.jp/ja/news_data/h/h1/news6/2009/090407_1.htm 269 1535-6108 4 Cancer Cell 255 15 Elsevier CELLCYCLE Rb Regulates DNA Damage Response and Cellular Senescence through E2F-Dependent Suppression of N-Ras Isoprenylation 2433/77906 Gotoh, Yasuhito 2002/03/25 Kyoto University 液体金属イオン源を用いた新奇金属イオンビーム装置の開発 Development of Novel Metal Ion Beam Systems with Liquid-Metal Ion Sources 2433/39799 Tsuji, H 2000/01/30 799 0034-6748 2 REVIEW OF SCIENTIFIC INSTRUMENTS 797 http://link.aip.org/link/?rsi/71/797 71 AMER INST PHYSICS A negative ion beam application to artificial formation of neuron network in culture 2433/39801 Gotoh, Y 2000/01/30 1005 0034-6748 2 REVIEW OF SCIENTIFIC INSTRUMENTS 1002 http://link.aip.org/link/?rsi/71/1002 71 AMER INST PHYSICS Application of compact microwave ion source to low temperature growth of transition metal nitride thin films for vacuum microelectronics devices 2433/39680 Kim, SW 2006/06/19 0003-6951 25 APPLIED PHYSICS LETTERS http://link.aip.org/link/?apl/88/253114 88 AMER INST PHYSICS Catalyst-free synthesis of ZnO nanowall networks on Si3N4/Si substrates by metalorganic chemical vapor deposition 2433/39670 Kim, SW 2005/04/11 0003-6951 15 APPLIED PHYSICS LETTERS http://link.aip.org/link/?apl/86/153119 86 AMER INST PHYSICS ZnO nanowires with high aspect ratios grown by metalorganic chemical vapor deposition using gold nanoparticles 2433/39690 Tsutsui, M 2006/10/16 0003-6951 16 APPLIED PHYSICS LETTERS http://link.aip.org/link/?apl/89/163111 89 AMER INST PHYSICS High-conductance states of single benzenedithiol molecules 2433/39956 Suzuki, M 2005/05/30 192 1051-8223 2 IEEE TRANSACTIONS ON APPLIED SUPERCONDUCTIVITY 189 15 IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC Characteristic relationship between the maximum Josephson current and the c-axis conductivity observed for intrinsic Josephson junctions in Bi-Sr-Ca-Cu-O 2433/39643 Tanaka, I 2001/04/09 2136 0003-6951 15 APPLIED PHYSICS LETTERS 2134 http://link.aip.org/link/?apl/78/2134 78 AMER INST PHYSICS Electron energy loss near-edge structures of cubic Si3N4 2433/39813 Fukuma, T 2005/11/29 0034-6748 12 REVIEW OF SCIENTIFIC INSTRUMENTS http://link.aip.org/link/?rsi/76/126110 76 AMER INST PHYSICS Frequency-modulation atomic force microscopy at high cantilever resonance frequencies using the heterodyne optical beam deflection method 2433/49851 Mukai, SA 2003/09/29 2559 0003-6951 13 APPLIED PHYSICS LETTERS 2557 http://link.aip.org/link/?apl/83/2557 83 AMER INST PHYSICS Liquid/liquid dynamic phase separation induced by a focused laser 2433/46904 Komoto, Hiroshi 1966/10/30 111 0034-6675 2 The Review of Physical Chemistry of Japan 105 37 The Physico-Chemical Society of Japan Physico-chemical studies of polyamides I : polyamides having long methylene chain units 2433/134550 Ichitsubo, T. 2010/10/30 This letter reports the control of the c-axis orientation and the magnetic properties of L10 FePd in the well-annealed FePd/Fe thin films Fe(20 nm)/FePd(10 nm)/Fe(5 nm)/SiO2-substrate and Fe(20  nm)/FePd(5 nm)/Fe(5 nm)/SiO2-substrate, with the compositions of dual phase region in phase equilibrium.

Strongly correlated electrons with greatly enhanced effective mass are present in heavy fermion compounds, whose electronic structure is essentially three-dimensional. We realized experimentally a two-dimensional heavy fermion system, adjusting the dimensionality in a controllable fashion. Artificial superlattices of the antiferromagnetic heavy fermion compound CeIn3 and the conventional metal LaIn3 were grown epitaxially. By reducing the thickness of the CeIn3 layers, the magnetic order was suppressed and the effective electron mass was further enhanced. Heavy fermions confined to two dimensions display striking deviations from the standard Fermi liquid low-temperature electronic properties, and these are associated with the dimensional tuning of quantum criticality. 2次元空間に「最も重い電子」を実現. 京都大学プレスリリース. 2010-02-19. http://www.kyoto-u.ac.jp/ja/news_data/h/h1/news6/2009/100219_1.htm 983 1095-9203 5968 Science 980 327 American Association for the Advancement of Science Tuning the dimensionality of the heavy fermion compound CeIn3. 2433/108636 Ito, Tatsunori 1986/11/29 New terminology for the morphology of first stage nauplius y larvae, mainly for the plates on their cephalic shield, is proposed.

It is found that when the gold nanoparticle size is smaller than a few nanometers, gold atoms preferentially attach to specific sites on the TiO2 surface and thus form an epitaxial and coherent heterointerface. Conversely, as the gold size becomes larger, the gold-TiO2 interface loses lattice coherency in order to accommodate the large lattice mismatch between the two dissimilar crystals. 0031-9007 13 PHYSICAL REVIEW LETTERS http://link.aps.org/doi/10.1103/PhysRevLett.102.136105 102 American Physical Society Interface Structures of Gold Nanoparticles on TiO2 (110) 2433/109896 Feng, Gan 2009/02/27 4H-SiC epilayers have been characterized by microphotoluminescence (micro-PL) spectroscopy and micro-PL intensity mapping at room temperature. A type of stacking fault (SF) with a peak emission wavelength at 480 nm (2.58 eV) has been identified. The shape of this SF is triangular revealed by the micro-PL intensity mapping. Conventional and high-resolution transmission electron microscopies have been carried out to investigate the structure of this SF. Its stacking sequence is determined as (3,5) in Zhdanov’s notation, which is consistent with that of the triple Shockley SF. The formation mechanism of this SF is also discussed. 0003-6951 9 APPLIED PHYSICS LETTERS http://link.aip.org/link/APPLAB/v94/i9/p091910/s1 94 American Institute of Physics photoluminescence Triple Shockley type stacking faults in 4H-SiC epilayers 2433/109898 Fujita, Koji 2009/01/30 We report on epitaxial growth and magnetic properties of EuTiO3 thin films with a perovskite structure. Single crystalline EuTiO3 films with atomically flat surface are grown on (001) surface of SrTiO3 by pulsed laser deposition (PLD) and subsequent annealing in reducing atmosphere. The as-deposited films possess the crystal structure with an elongated c-axis and tend to stabilize ferromagnetically ordered Eu2+ spins at low temperatures. Postannealing at 1000 °C relaxes the out-of-plane lattice strain, and brings about a drastic change in magnetic structure; the annealed film becomes an antiferromagnet below Néel temperature of 5.1 K. The change in magnetic properties accompanied by the modification in lattice constant is discussed. 0003-6951 6 APPLIED PHYSICS LETTERS http://link.aip.org/link/APPLAB/v94/i6/p062512/s1 94 American Institute of Physics annealing High-quality antiferromagnetic EuTiO3 epitaxial thin films on SrTiO3 prepared by pulsed laser deposition and postannealing 2433/57239 Makabe, Kazuhiro W. 1992/05/30 Muscle cells of the ascidian tadpole larva originate from two different lineages, the primary (B4.1 line) and secondary (A4.1 and b4.2 lines) lineages. Experiments with 8-cell embryos have indicated that isolated blastomeres of the primary lineage show autonomous muscle development, whereas blastomeres of the secondary lineage rarely develop the differentiation markers (muscle-specific antigens and specific enzyme activity) in isolation. However, there is the possibility that A4.1 and b4.2 quarter embryos might express a muscle-specific gene but the transcripts might not be translated into proteins, thus we would not be able to detect the muscle differentiation. In order to examine the possibility, four blastomere-pairs (a4.2, b4.2, A4.1, and B4.1 pairs), isolated from the 8-cell embryo of Halocynthia roretzi, were allowed to develop into quarter embryos, and the occurrence of transcripts of myosin heavy-chain gene was determined by in situ hybridization of whole-mount specimens. The transcripts were evident only in B4.1 quarter embryos and not in A4.1, b4.2 and a4.2 quarter embryos. Thus, the proportion of A4.1 and b4.2 quarter embryos that develop muscle cells does not increase even when examined at the transcriptional level. 573 0289-0003 3 Zoological Science 569 9 Zoological Society of Japan Failure of Muscle Myosin Heavy-Chain Gene Expression in Quarter Ascidian Embryos Developed from the Secondary Muscle Lineage Cells(Developmental Biology) 2433/123444 Shen, Yanna 2010/05/30 Toll-like receptors (TLRs) play a key role in the innate immune response by sensing bacterial ligands. The mechanisms involved in the TLR-mediated cytokine response are well established; however, the possible contribution of TLR-dependent recognition of bacteria to macrophage phagocytosis remains unclear. Listeria monocytogenes is an intracellular, parasitic, Gram-positive bacterium recognized mainly by TLR2. In this study, we investigated whether TLR2-dependent signaling is involved in the phagocytosis of L. monocytogenes by macrophages. We found no difference in the number of L. monocytogenes cells associating with wild-type (WT) and TLR2(-/-) macrophages 1 h after infection. However, the number of L. monocytogenes cells phagocytosed in TLR2(-/-) and MyD88(-/-) macrophages was significantly lower than that of WT macrophages. In addition, lipopolysaccharide (LPS) treatment restored impaired phagocytic activity of TLR2(-/-) macrophages but did not enhance the activity of MyD88(-/-) macrophages. The efficiency of phagocytosis was suppressed by inhibitors of phosphatidylinositol 3-kinase (PI3K) and the small Rho GTPases but not by cycloheximide. Moreover, functional activation of PI3K and Rac1 was impaired in TLR2(-/-) and MyD88(-/-) macrophages. In an in vivo infection model, we found significantly lower numbers of L. monocytogenes cells phagocytosed in peritoneal macrophages of TLR2(-/-) and MyD88(-/-) mice after intraperitoneal infection. Moreover, a lower number of bacteria were detected in the spleens of TLR2(-/-) mice 1 day after intravenous infection than in WT mice. These results clearly indicated that TLR2-MyD88-dependent signaling enhances the basal level of phagocytosis of L. monocytogenes by macrophages through activation of PI3K and Rac1, not by synthesis of proinflammatory cytokines or expression of phagocytic receptors. 2867 0019-9567 6 Infection and immunity 2857 78 TLR2-MyD88-dependent PI3K and Rac1 activation facilitates the phagocytosis of Listeria monocytogenes by murine macrophages Toll-like receptor 2- and MyD88-dependent phosphatidylinositol 3-kinase and Rac1 activation facilitates the phagocytosis of Listeria monocytogenes by murine macrophages. 2433/157631 Kumatoriya, Makoto 2012/03/26 Kyoto University 無機材料 組成制御が無機結晶の電気的・光学的性質に与える影響の研究 Studies of Influence of Compositional Modification on Electrical and Optical Properties of Inorganic Materials 2433/157619 Liu, Yi-Hung 2012/03/26 Kyoto University Dry ice ドライアイス微粒子の形成プロセスの解析と表面洗浄への応用 Analysis of Production Process of Fine Dry Ice Particles and Application for Surface Cleaning 2433/158582 MITSUI, Takashi 1969/08/31 139 0006-5420 3 防虫科学 135 34 財団法人防虫科学研究所 19.ピエリシジンに関する研究 II : ピエリシジンA関連化合物の殺虫作用およびミトコンドリアの電子伝達系に及ぼす影響 Studies on Piericidin.

We found that nitric oxide (NO) directly activates RyRs, which induce Ca(2+) release from intracellular stores of central neurons, and thereby promote prolonged Ca(2+) signalling in the brain. Reversible S-nitrosylation of type 1 RyR (RyR1) triggers this Ca(2+) release. NO-induced Ca(2+) release (NICR) is evoked by type 1 NO synthase-dependent NO production during neural firing, and is essential for cerebellar synaptic plasticity. NO production has also been implicated in pathological conditions including ischaemic brain injury, and our results suggest that NICR is involved in NO-induced neuronal cell death. These findings suggest that NICR via RyR1 plays a regulatory role in the physiological and pathophysiological functions of the brain. 428 0261-4189 2 The EMBO journal 417 31 Nature Publishing Group calcium Nitric oxide-induced calcium release via ryanodine receptors regulates neuronal function. 2433/160652 Chen, Tao 2011/10/01 We studied the photoluminescence (PL) from black silicon that was fabricated using an 800 nm, 250 kHz femtosecond laser in air. By changing the scan velocity and the fluence of the femtosecond laser, the formation of the PL band between the orange (600 nm) and red bands (near 680 nm) could be controlled. The red band PL from the photoinduced microstructures on the black silicon was observed even without annealing due to the thermal accumulation of high-repetition rate femtosecond laser pulses. The orange band PL was easily quenched under 532 nm cw laser irradiation, whereas the red band PL was more stable; this can be attributed to "defect luminescence" and "quantum confinement", respectively. 0021-8979 7 JOURNAL OF APPLIED PHYSICS http://link.aip.org/link/?jap/110/073106 110 American Institute of Physics elemental semiconductors Luminescence of black silicon fabricated by high-repetition rate femtosecond laser pulses 2433/160763 Fujita, Katsuhiko 1995/03/23 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University α-ヘリックス形成ペプチドに基づく,脂質膜中及び気/液界面での高次構造形成 Supramolecular Assembly Containing α-Helical Peptide Molecules in Lipid Bilayer Membrane and at the Air/Water Interface 2433/166878 山本 1934/08/25 411 161 天界 = The heavens 406 14 東亞天文協會 天文用語に関する私見と主張(3) 天文用語に關する私見と主張(3) 2433/74845 Hyon, Suong-hyu 1978/05/23 Kyoto University 分子配向下の結晶化,及び配向処理をほどこした結晶性高分子の構造と物性 Structure and Properties of Crystalline Polymers,Crystallized or Processed under Molecular Orientation 2433/134579 Suh, Min-Soo 2010/12/24 A novel challenge, the in situ crystallization of Pre-SiC reinforced-fiber during the fabrication of SiC/SiC composites, has been made for cost effectiveness. Constituent parts of each fabricated material with various manufacturing conditions were assessed by microscopic observation. The depending issues of a prototype process were rather serious that the unwanted areas were conspicuously observed in several places, such as a residual oxide area, unsintered area, course matrix, porosity along the fiber-tows, and a huge scale of deformation on fiber-tows. Crystallization process of Pre-SiC fiber itself caused volume contraction about 24.5%, which result in formation of a gap between the fiber-tow and pyrolytic carbon (PyC) interface. The optimization has been successfully made for a new fabrication technique by controlling most of the known defects. As a result, defects are rarely observed in final product of composite material. 0022-3115 Journal of Nuclear Materials Elsevier B.V.

On Congo red staining, amyloid was visualized as orange material, showing characteristic birefringence under polarized light. Amyloidosis of the urethra was diagnosed. Because the patient refused to undergo duodenal or rectal biopsy, the possibility of systemic amyloidosis could not be completely excluded.

ChM-I comprises two domains: an N-terminal hydrophilic domain (domain 1) containing an N-linked glycosylation site and a C-terminal hydrophobic domain (domain 2) with all four disulfide bonds that are present in this protein. We generated a nonglycosylated recombinant human ChM-I (NG-hChM-I) and compared its bioactivity with that of the glycosylated form of human ChM-I (G-hChM-I) expressed in Chinese hamster ovary cells in vitro. NG-hChM-I exhibited the growth factor/inhibitor activity in the cultures of chondrocytes and vascular endothelial cells but required markedly higher doses. Although domain 1 is predicted to be hydrophilic per se on the basis of its amino acid sequence, NG-hChM-I remains insoluble in aqueous solution as much as ΔN-hChM-I that lacks the N-terminal 37 amino acids containing an N-glycosylation site. Circular dichroism measurements revealed that the content of α-helix was calculated to be 34% in G-hChM-I, whereas the content of the characteristic secondary structures in NG-hChM-I was distinctly lower than those in G-hChM-I. These results indicate that glycosylation in domain 1 is critical for the structural integrity for biological functions of ChM-I in vitro. 30 0914-8779 1 Journal of bone and mineral metabolism 23 29 The Japanese Society for Bone and Mineral Research and Springer Chondromodulin-I A functional role of the glycosylated N-terminal domain of chondromodulin-I. 2433/134601 Sugano, Koji 2010/11/29 Gold nanoparticles with diameters of a few tens of nanometer and a narrow size distribution were synthesized using a pulsed mixing method with a microfluidic system which consists of a Y-shaped mixing microchannel and two piezoelectric valveless micropumps. This mixing method enables control of the mixing speed of gold salts and reducing agent by changing the switching frequency of the micropumps, which was our focus to improve the particle size distribution, which is an essential parameter in gold nanoparticle synthesis. In the proposed method, the mixing time was inversely proportional to the switching frequency and the minimum mixing time was 95 ms at a switching frequency of 200 Hz. During synthesis experiments, the mean diameter of the synthesized gold nanoparticles was found to increase, and the coefficient of variation of particle size was found to decrease with decreasing mixing time. We successfully improved the coefficient of variation to less than 10% for a mean diameter of around 40 nm. 1174 1613-4982 6 Microfluidics and Nanofluidics 1165 9 Springer-Verlag Gold nanoparticle Mixing speed-controlled gold nanoparticle synthesis with pulsed mixing microfluidic system 2433/139424 Yang, Kai-Chiang 2010/03/19 Immune rejection and scarcity of donor tissues are the restrictions of islets transplantation. In this study, the cytoprotection of chitosan hydrogels in xenogeneic islet transplantation was demonstrated. Wistar rat islets encapsulated in chitosan hydrogels were performed glucose challenge test and live/dead cell staining in vitro. Islets/chitosan hydrogels were transplanted into the renal subcapsular space of diabetic C57BL/6 mice. Non-fasting blood glucose level (NFBG), body weight, intraperitoneal glucose tolerance test (IPGTT), and glucose disappearance rate were determined perioperatively. The serum insulin level was analyzed, and the kidney transplanted with islets/chitosan hydrogels were retrieved for histological examination after sacrifice. The present results showed that islets encapsulated in chitosan hydrogels secreted insulin in response to the glucose stimulation as naked islets with higher cell survival. The NFBG of diabetic mice transplanted with islets/chitosan hydrogels decreased from 487+/-46 to 148+/-32 at one day postoperation and maintained in the range of 201+/-36 mg/dl for four weeks with an increase in body weight. IPGTT showed the glucose disappearance rate of mice transplanted with islets/chitosan hydrogels was significant faster than that of mice transplanted with naked islets; the serum insulin level increased from 0.29+/-0.06 to 1.69+/-0.65 microg/dl postoperatively. Histological examination revealed that the islets successfully engrafted at renal subcapsular space with positive insulin staining. The immunostain was negative for neither the T-cell lineages nor the monocyte/macrophages. This study indicates that the chitosan hydrogels deliver and protect encapsulated islets successfully in xenotransplantation. 823 0006-291X 4 Biochemical and biophysical research communications 818 393 Elsevier Inc.

We have recently shown that mitogen-activated protein kinases (MAPKs) activated by thrombin exacerbate hemorrhagic brain injury via supporting survival of neuropathic microglia. Here, we investigated whether induction of heme oxygenase (HO)-1 is involved in these events. Zinc protoporphyrin IX (ZnPP IX), a HO-1 inhibitor, attenuated thrombin-induced injury of cortical cells in a concentration-dependent manner (0.3-3 microM) and tended to inhibit shrinkage of the striatal tissue at 0.3 microM. HO-1 expression was induced by thrombin in microglia and astrocytes in both the cortex and the striatum. The increase of HO-1 protein was suppressed by a p38 MAPK inhibitor SB203580, and early activation of p38 MAPK after thrombin treatment was observed in neurons and microglia in the striatum. Notably, concomitant application of a low concentration (0.3 microM) of ZnPP IX with thrombin induced apoptotic cell death in striatal microglia and significantly decreased the number of activated microglia in the striatal region. On the other hand, a carbon monoxide releaser reversed the protective effect of ZnPP IX on thrombin-induced injury of cortical cells. Overall, these results suggest that p38 MAPK-dependent induction of HO-1 supports survival of striatal microglia during thrombin insults. Thrombin-induced cortical injury may be also regulated by the expression of HO-1 and the resultant production of heme degradation products such as carbon monoxide. 178 0006-8993 Brain research 170 1347 Elsevier B.V.

X-shaped DNA (X-DNA) was designed as a building unit, and underwent ligation to form DNA hydrogels. Two types of X-DNA were constructed using four oligodeoxynucleotides each, one containing six potent CpG motifs (CpG X-DNA) and the other with none (CpG-free X-DNA). CpG X-DNA was more effective than its components or the CpG-free counterpart in terms of the production of tumor necrosis factor-α from murine macrophage-like RAW264.7 cells, as well as maturation of the murine dendritic DC2.4 cells. The cytotoxic effects of X-DNA, DXR and their complexes were examined in a co-culture system of colon26/Luc cells, a murine adenocarcinoma clone stably expressing firefly luciferase, and RAW264.7 cells. DXR/CpG X-DNA showed the highest ability to inhibit the proliferation of colon26/Luc cells. DXR was slowly released from CpG DNA hydrogels. Injections of DXR/CpG DNA hydrogels into a subcutaneous colon26 tumor effectively inhibited tumor growth. These results show that CpG DNA hydrogels are an effective sustained system for delivery of immunostimulatory signals to TLR9-positive immune cells and DXR to cancer cells. 0142-9612 Biomaterials Elsevier Ltd.

Population-level laterality can be explained mainly by internal factors (e.g., cerebral lateralization), whereas little is known about the behavioural mechanisms underlying individual-level laterality. Recently, it was revealed that many fish have asymmetrical body morphology, but the relationship between asymmetric morphology and social behaviours has been rarely examined. Here we report the relationship between lateralized eye use during aggressive displays (e.g., body posture) of male Siamese fighting fish, Betta splendens, toward their own mirror image and morphological asymmetry. Of 25 males, five exhibited significantly more leftward eye use during left displays, and eight males exhibited predominantly rightward eye use during right displays. Morphological measurement results for the craniovertebral angle and opercular area showed that the craniovertebral angle and opercular area displayed antisymmetry and fluctuating asymmetry, respectively. We found that lateralized eye use during agonistic responses by each fish was associated with the craniovertebral angle, but not with operculum size; lefties (left-curved body) showed mainly left eye use (during left-side displays), and righties (right-curved body) demonstrated the opposite. We suggest that antisymmetric morphologies, such as head incline, are potentially useful for studying the association between cerebral lateralization and individual laterality of behavioural responses. Further, we propose that in fish, morphological asymmetry is related to laterality in various behaviours. 111 0166-4328 1 Behavioural brain research 106 208 Elsevier B.V. Cerebral lateralization Lateral bias of agonistic responses to mirror images and morphological asymmetry in the Siamese fighting fish (Betta splendens). 2433/138087 Makino, Akira 2011/02/27 Three types of nanocarriers from our group for imaging probes are reviewed here. Novel nanocarriers of “peptosome” and “lactosome” were prepared from amphiphilic polymers uniquely having a helical segment as a hydrophobic block. Apoferritin was chemically modified on the surface, and used for nanocontainer of a novel Gd-chelator. Lactosome was intensively studied and labeled with indocyanine, 18F, and 131I for tumor imaging by NIRF, PET, and SPECT, respectively. Those labeled lactosomes are shown to be effective for tumor imaging on the basis of the EPR effect and the stealth property in vivo. The superiority of lactosome over other commercially available imaging agents is experimentally confirmed, which is explained by the dense and thick hydrophilic polymer brush formed on the surface and the helix bundles at the hydrophobic core. Our final goal is to develop the next-generation lactosome, which is the nanocarrier which is usable for a diagnostic agent and a therapeutic agent showing the same in vivo disposition even upon frequent administration. 279 1381-5148 3 Reactive and Functional Polymers 272 71 Elsevier Ltd Molecular assembly Preparation of peptide- and protein-based molecular assemblies and their utilizations as nanocarriers for tumor imaging 2433/139526 Tajino, Koji 2011/02/27 We have shown that cutaneous cooling-sensitive receptors can work as thermostats of skin temperature against cooling. However, molecule of the thermostat is not known. Here, we studied whether cooling-sensitive TRPM8 channels act as thermostats. TRPM8 in HEK293 cells generated output (y) when temperature (T) was below threshold of 28.4°C. Output (y) is given by two equations: At T >28.4°C, y = 0; At T <28.4°C, y  =  -k(T - 28.4°C). These equations show that TRPM8 is directional comparator to elicits output (y) depending on negative value of thermal difference (ΔT  =  T - 28.4°C). If negative ΔT-dependent output of TRPM8 in the skin induces responses to warm the skin for minimizing ΔT recursively, TRPM8 acts as thermostats against cooling. With TRPM8-deficient mice, we explored whether TRPM8 induces responses to warm the skin against cooling. In behavioral regulation, when room temperature was 10°C, TRPM8 induced behavior to move to heated floor (35°C) for warming the sole skin. In autonomic regulation, TRPM8 induced activities of thermogenic brown adipose tissue (BAT) against cooling. When menthol was applied to the whole trunk skin at neutral room temperature (27°C), TRPM8 induced a rise in core temperature, which warmed the trunk skin slightly. In contrast, when room was cooled from 27 to 10°C, TRPM8 induced a small rise in core temperature, but skin temperature was severely reduced in both TRPM8-deficient and wild-type mice by a large heat leak to the surroundings. This shows that TRPM8-driven endothermic system is less effective for maintenance of skin temperature against cooling. In conclusion, we found that TRPM8 is molecule of thermostat of skin temperature against cooling. 1932-6203 3 PloS one 6 Public Library of Science Cooling-Sensitive TRPM8 Is Thermostat of Skin Temperature against Cooling. 2433/139590 Yoshino, Namiko 2011/04/29 Lindernia procumbens and L. dubia are common annual weeds in flooded rice fields of Japan. Two subspecies of L. dubia, subsp. major and subsp. dubia, are usually recognized in Japan but they are both regarded as synonyms of L. dubia elsewhere. In a cluster analysis based on AFLP, most L. dubia subsp. major formed a separate cluster from L. dubia subsp. dubia although 11% of haplotypes classified using AFLP were not coincident with classification using the shape of leaf bases, which is the commonly used identification trait. Artificial F1 plants between L. procumbens and L. dubia subsp. major, and between L. procumbens and L. dubia subsp. dubia did not produce seed. Forty percent of capsules produced by F1 plants from these two subspecies were slimmer and 80% pollen were sterile in slimmer capsules. However, seed number of most F1 capsules was not different from that of self-fertilized plants, suggesting that there was no complete reproductive isolation between the subspecies. Natural hybridization of these subspecies may have occurred but we are not aware of it because F1 plants are rare and F2 plants are indistinguishable from these subspecies. 171 0304-3770 4 Aquatic Botany 165 94 Elsevier B.V.

Exercise training (45 min swimming, 3 times/week) was conducted, and behavioral stress was provoked by glass marble-burying procedure. Mice were treated with marble-burying, marble-burying behavior plus swimming training, and swimming alone over 8 weeks.　　Results： Exercise training decreased the atherosclerotic lesions, but marble-burying behavior increased the lesions. The plaques containing macrophage accumulation with intercellular adhesion molecule-1 (ICAM-1) expression associated with reduced collagen contents were induced in the mice treated with marble-burying. However, ICAM-1 expression was suppressed and collagen contents were reversed in the mice that received marble-burying behavior plus exercise training. In addition, exercise alone and concomitant exercise training reduced the superoxide production in aortic walls, shown by dihydroethidium staining, compared with that in mice with marble-burying behavior alone. There were no significant differences in the serum lipids profiles among the groups.　　Conclusions： Behavioral stress increased the atherosclerotic lesions and induced the adhesion molecule expression with superoxide production on the lesions in apo E-deficient mice. Exercise training may stabilize plaque lesions induced by marble-burying behavior in this animal model. 289 0167-5273 3 International journal of cardiology 284 151 Elsevier Ireland Ltd.

With decreasing the thickness of the bottom d-PS layer, Tg near the interface between the polymer thin film and substrate increased compared to bulk Tg and a drastic increase of Tg was observed for the bottom d-PS layer <155 Å thick. The orientation of polymer chains at the interface is supposed to be related to the increase of Tg near the interface between the polymer and substrate. The polymer chain mobility decreased with thickness even for the bottom d-PS layer with no discernible change of Tg. It is considered that the numerous contacts between polymer chains and substrate are related to the decrease of mobility near the interface between the polymer thin film and substrate. 1539-3755 3 Physical Review E 84 American Physical Society Interfacial properties of polystyrene thin films as revealed by neutron reflectivity 2433/148015 Ali, Arwa M 2011/09/29 Circulating endothelial cells (CECs) have been studied as a biomarker for tumour progression and monitoring therapeutic effects.

The dimer consists of hydrogen-bond donor and acceptor molecules, and dynamically rearranges the hydrogen bond, resulting in the interchange of their roles. The large isotope effect (~60) was observed in the interchange rate between (H[2]O)[2] and (D[2]O)[2], suggesting that the process involves quantum tunneling. The interchange motion was enhanced upon the excitation of a specific vibration mode that correlates with the reaction coordinate. 42 1348-317X 低温物質科学研究センター誌 : LTMセンター誌 36 14 低温物質科学研究センター Real-Space Observation of Hydrogen-Bond Exchange in Water Clusters <研究ノート>水クラスターにおける水素結合交換の実空間観測 2433/153279 Higaki, Sayuri 2012/01/30 Changes in the expression of estrogen-related substances in monkeys' brains at the menopausal transition, when estrogen deficit starts to occur, have not yet been examined thoroughly. In the present study, we immunohistochemically investigated the expression levels of estrogen receptor beta (ERβ) and aromatase (local estrogen synthesizing enzyme) in the hippocampal formation of premenopausal, menopausal, and ovariectomized premenopausal monkeys. In all monkeys tested, ERβ immunoreactivity was observed in interneurons located in the subiculum and the Ammon's horn, and most of these ERβ-immunoreactive neurons coexpressed a GABAergic neuron marker, parvalbumin. In the menopausal monkeys who exhibited a decline in estrogen concentration, hippocampal ERβ was highly upregulated, while aromatase expression was not markedly changed. By contrast, aromatase in the ovariectomized monkeys was significantly upregulated, while ERβ expression was not changed. In the brains of ovariectomized and menopausal monkeys, depletion of ovary-derived estrogen brought about different reactions which may be attributed to the senescence of brain aging. 154 0168-0102 2 Neuroscience research 148 72 Elsevier Ireland Ltd and the Japan Neuroscience Society Estrogen receptor beta Response of ERβ and aromatase expression in the monkey hippocampal formation to ovariectomy and menopause. 2433/156290 Horie, Rie T 2010/10/30 This study aimed to investigate the efficacy of encapsulating steroids, which is a primary choice for the treatment of sensorineural hearing loss, in polyethylene glycol-coated polylactic acid nanoparticles for drug delivery to the cochlea. 1340 1743-5889 9 Nanomedicine 1331 5 Future Medicine Ltd.

However, taxane-related drug resistance and neurotoxicity have prompted us to develop substitute treatment strategies. Eg5 (kinesin spindle protein), which is crucial for bipolar spindle formation and duplicated chromosome separation during the early phase of mitosis, has emerged as an attractive target for cancer chemotherapy. The aim of this study was to investigate the anticancer efficacy of S-(methoxytrityl)-L-cysteine (S(MeO)TLC), a novel Eg5 inhibitor in prostate cancer. Eg5 expression was examined in human prostate cancer cell lines and tissue microarrays were constructed from clinical specimens. Antiproliferative activity of S(MeO)TLC in prostate cancer cells was assessed by a cell viability assay. The anticancer effect and inhibitory mechanism of S(MeO)TLC in prostate cancer cells was further explored by Hoechst staining, flow cytometry and immunofluorescence. In addition, the antitumor effect of S(MeO)TLC on subcutaneous xenograft models was assessed. Eg5 expression was identified in PC3, DU145 and LNCaP cells. More than half of prostate cancer clinical specimens displayed Eg5 expression. S(MeO)TLC exhibited more powerful anticancer activity in prostate cancer cells compared with the other four Eg5 inhibitors tested. S(MeO)TLC induced cell death after arresting dividing cells at mitosis with distinct monopolar spindle formation. S(MeO)TLC exhibited its significant inhibitory activity (P<0.05) on subcutaneous xenograft models also through induction of mitotic arrest. We conclude that Eg5 is a good target for prostate cancer chemotherapy, and S(MeO)TLC is a potent promising anticancer agent in prostate cancer. 241 1008-682X 2 Asian journal of andrology 236 13 Nature Publishing Group Eg5 protein A potent chemotherapeutic strategy in prostate cancer: S-(methoxytrityl)-L-cysteine, a novel Eg5 inhibitor. 2433/156992 Niwano, Mototaka 1998/07/23 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University 担癌ラットを用いた血管新生阻害剤TNP-470の抗腫瘍効果及び微細血管新生阻害効果の検討 The Inhibition of Tumor Growth and Microvascular Angiogenesis by the Potent Angiogenesis inhibitor, TNP-470 in Rats 2433/157927 Hama, Takayuki 2012/07/30 This paper presents the work-hardening behaviors of a rolled AZ31B magnesium alloy sheet during in-plane cyclic loading. The overall trend of the stress–strain curve was as follows. As established before, the yield stress under compression was considerably less than that under tension, and an inflected shape was observed in the stress–strain curve during the subsequent tension. Furthermore, an asymmetric evolution of work-hardening was observed as follows. The rate of work-hardening in the late stage of compression became gradually large with an increase in the number of cycles. Owing to this increase in the rate of work-hardening, the stress at the end of compression increased as the number of cycles increased. On the other hand, the rate of work-hardening in the late stage of tension became small as the number of cycles increased, yielding a decrease in the stress at the end of tension with the increase in the number of cycles. The results were almost the same when the cyclic loading test was carried out after tensile strain was applied to the sheet. On the other hand, when the cyclic loading test was carried out after compressive strain was applied, the increase in the rate of work-hardening in the late stage of compression was significantly more pronounced, whereas the inflected shape of the curve during tension was considerably less pronounced. The mechanisms of the above macroscopic behaviors were investigated in terms of twinning. 217 0921-5093 Materials Science and Engineering: A 209 551 Elsevier B.V.

Two types of thin films were prepared; one is a single-layered thin film, and the other is a multilayered film, [FePd(x nm)/Fe(5 nm)]_n (x: thickness, n: the number of multilayers), both of which are deposited on silica glass substrates. For single-layered films, the ordering process is retarded by phase separation that requires long-range diffusion. In this case, the 〈111〉 oriented domains preferentially grow from the film surface, and the c-axis-oriented structure is not obtained. On the contrary, for multilayered films, each FePd layer can undergo ordering without phase separation subject to the constraint of strong biaxial tensile stress resulting from the difference in the thermal contractions between Fe/FePd film and the silica glass substrate. Consequently, the L1_0 domains with c-axis orientation in the normal direction of the film surface are preferentially formed in the initial amorphouslike structure, eventually leading to the desired c-axis-oriented structure. 0021-8979 3 Journal of Applied Physics 109 American Institute of Physics amorphous state Control of c-axis orientation of L1_0-FePd in dual-phase-equilibrium FePd/Fe thin films 2433/85228 Adachi, Taiji 2009/07/30 It is proposed that osteocytes embedded in the bone matrix have the ability to sense deformation and/or damage to the matrix and to feed these mechanical signals back to the adaptive bone remodeling process. When osteoblasts differentiate into osteocytes during the bone formation process, they change their morphology to a stellate form with many slender processes. This characteristic cell shape may underlie the differences in mechanosensitivity between the cell processes and cell body. To elucidate the mechanism of cellular response to mechanical stimulus in osteocytes, we investigated the site-dependent response to quantitatively controlled local mechanical stimulus in single osteocytes isolated from chick embryos, using the technique of calcium imaging. A mechanical stimulus was applied to a single osteocyte using a glass microneedle targeting a microparticle adhered to the cell membrane by modification with a monoclonal antibody OB7.3. Application of the local deformation induced calcium transients in the vicinity of the stimulated point and caused diffusive wave propagation of the calcium transient to the entire intracellular region. The rate of cell response to the stimulus was higher when applied to the cell processes than when applied to the cell body. In addition, a large deformation was necessary at the cell body to induce calcium transients, whereas a relatively small deformation was sufficient at the cell processes, suggesting that the mechanosensitivity of the cell processes was higher than that of the cell body. These results suggest that the cell shape with slender processes contributes to the site-dependent mechanosensitivity in osteocytes. 1995 00219290 12 Journal of Biomechanics 1989 42 Elsevier Bone cells Calcium response in single osteocytes to locally applied mechanical stimulus: Differences in cell process and cell body 2433/85300 Masunaga, Shin-ichiro 2009/07/30 Purpose To elucidate the effect of tumor oxygenation status on recovery from damage following γ-ray or accelerated carbon ion irradiation in vivo, including in quiescent (Q) cells. Methods SCC VII tumor-bearing mice were continuously given 5-bromo-2′-deoxyuridine (BrdU) to label all proliferating (P) cells. They received γ-ray or accelerated carbon ion irradiation with or without tumor clamping for inducing hypoxia. Immediately after irradiation, cells from some tumors were isolated, or acute hypoxia-releasing nicotinamide was loaded to the tumor-bearing mice. For 9 h after irradiation, some tumors were kept aerobic or hypoxic. Then isolated tumor cells were incubated with a cytokinesis blocker. The response of Q cells was assessed in terms of the micronucleus frequency using immunofluorescence staining for BrdU. That of the total (=P + Q) tumor cells was determined from BrdU non-treated tumors. Results Clearer recovery in Q cells than total cells and after aerobic than hypoxic γ-ray irradiation was efficiently suppressed with carbon ion beams. Inhibition of recovery through keeping irradiated tumors hypoxic after irradiation and promotion of recovery by nicotinamide loading were observed more clearly with γ-rays, after aerobic irradiation and in total cells than with carbon ion beams, after hypoxic irradiation and in Q cells, respectively. Conclusions Tumor oxygenation status following irradiation can manipulate recovery from radiation-induced damage, especially after aerobic γ-ray irradiation in total cells. Carbon ion beams are promising because of their efficient suppression of the recovery. 1116 01715216 8 Journal of Cancer Research and Clinical Oncology 1109 135 Springer Verlag γ-Ray The effect of post-irradiation tumor oxygenation status on recovery from radiation-induced damage in vivo: With reference to that in quiescent cell populations 2433/85314 Takeuchi, Yuichi 2008/03/30 Morphological asymmetry and behavioral laterality in vertebrate species have been intensively studied in recent years, while comparable invertebrate studies are rare. Here we demonstrate asymmetry in the curvature of the abdomen and laterality in evasive responses for two atyid shrimps, Limnocaridina latipes and Neocaridina denticulata. The frequency distributions of the angle of the abdominal curvature in both species were discretely bimodal, suggesting that the two populations are composed of both left- and right-type individuals. In N. denticulata, behavioral analysis using high-speed filming illustrated that the escape direction for each individual, evoked by a sudden non-lateralized stimulus, was correlated with its abdominal curvature: left- (right-) type shrimp jumped back-leftward (-rightward) significantly more than often. A crossing experiment with N. denticulata indicated that the trait frequency in the F1 generation from two left-type parents differed significantly from that of the F1 generation from two right-type parents, and that the trait frequency for the F1 generation from parents of different laterality types did not deviate from random. That is, offspring laterality type is affected by the lateralities of the parents, indicating that abdominal dimorphism in shrimp is genetically derived. These results suggest that shrimp have an innate laterality that controls their escape direction, which in turn may affect prey-predator interactions in the aquatic community. 363 0289-0003 4 Zoological Science 355 25 Zoological Society of Japan abdominal curvature Morphological Asymmetry of the Abdomen and Behavioral Laterality in Atyid Shrimps 2433/89650 Shinya, Ryoji 2008/10/30 The present study was made to determine the binding patterns of several lectins to the surface coat (SC) proteins of various isolates and developmental stages of the pine wood nematode (PWN), Bursaphelenchus xylophilus. Also, the detailed characteristics of the SC proteins were profiled by using molecular techniques. The lectin-binding study demonstrated the stage-specific characters of SC in binding to the lectin, wheat germ agglutinin (WGA). WGA binding was observed only to the outer surfaces of third-stage propagative juveniles and to the egg shells, and this occurred more frequently in virulent than in avirulent PWN isolates. A greater variety of lectins bound to eggs than to any other life stage. For characterisation, the SC proteins extracted were separated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and analysed by lectin blotting. The results showed that the carbohydrate and protein patterns of the SC of the PWN changed during nematode development. 438 13885545 3 Nematology 429 11 Brill Academic Publishers Glycan Surface coat proteins of the pine wood nematode, Bursaphelenchus xylophilus: Profiles of stage- and isolate-specific characters 2433/46882 Osugi, Jiro 1967/04/30 73 0034-6675 2 The Review of Physical Chemistry of Japan 59 36 The Physico-Chemical Society of Japan High pressure transition in cadmium sulfide 2433/144642 DARAKRAI, KORAON WONGKAMHAENG ANUCHIT 2009/10/30 The amphipod Tethegeneia khanomensis sp. nov. were collected from South Sea Islands, lower Gulf of Thailand. in March 2008.

We measured the changes in transcriptional activity that accompanied the DNA conformational transitions. Complete inhibition was found at excess concentrations of nanoparticles. In contrast, at intermediate stages of DNA binding with nanoparticles, the transcription activity of DNA survived, and this strongly depended on the size of the nanoparticles. For large nanoparticles of 40 nm, a decrease in transcriptional activity can be caused by the addition of only a small amount of nanoparticles. On the other hand, there was almost no inhibition of DNA transcriptional activity with the addition of small nanoparticles (10 nm) until very high concentrations, even under conditions that induced DNA compaction as revealed by single-DNA observation. At higher concentrations of 10-nm nanoparticles, DNA transcription activity decreased abruptly until it was completely inhibited. These results are discussed in relation to the actual size of the histone core, together with the mechanism of switching of transcriptional activity in eukaryotic cells. 1325 0006-3495 4 Biophysical Journal 1318 92 Biophysical Society Transcription of Giant DNA Complexed with Cationic Nanoparticles as a Simple Model of Chromatin 2433/49167 Chen, Ning 2006/09/29 We propose a novel method for the simple visual (colorimetric) and spectroscopic monitoring of the conformational state of a biopolymer. We present an experimental example of the detection of the change in the conformation of a giant DNA molecule. This methodology is based on the difference in the manner of metallization with noble metals on a polymer scaffold depending on its conformation. Spectroscopic analysis of the metallization of DNA by metallic silver or gold provides information on the critical concentration of DNA binder, at which the folding transition from the elongated into the compact state occurs, together with the dimension and morphology of a compact DNA condensate. This method may be suitable for use in a rapid screening procedure for the high-throughput analysis of large chemical libraries to evaluate their ability to induce DNA compaction, protein folding and similar important processes. 5232 0957-4484 20 Nanotechnology 5224 17 IOP Probing biopolymer conformation by metallization with noble metals 2433/49160 Kidoaki, Satoru 2006/10/30 To investigate the relationship between cellular microelasticity and the structural features of cytoskeletons (CSKs), a microindentation test for apical cell membranes and observation of the spatio-distribution of actin CSKs of fibroblasts were performed by fluorescence and atomic force microscopy (FM/AFM). The indentation depths of apical cell membranes were measured from AFM force–indentation (f–i) curves under equal final loads and mapped two-dimensionally to show the relative distribution of local microelasticity on cell membranes. Intracellular spatial distribution of actin CSKs was visualized fluorescently by high Z-resolution cross-sectional observation of a cell on which indentation mapping analysis had been performed in advance. Structural features of stress fibers (SFs) were observed as three typical patterns of dense SF, sparse SF and sparser SF cell groups, which were quantitated using the degree of orientation in apical SFs (ASFs) that had been defined using two-dimensional Fourier analysis. In indentation depth maps, the upper nuclear region was markedly softer than the pseudopodium region. The mean indentation depth of the upper nuclear region decreased with increased SF density in whole cells and the degree of orientation of ASF, although the pseudopodium region did not exhibit such a trend. The apical membrane of adhered cells was found to tend to stiffen with the increase in both density and degree of orientation of SFs. 272 1617-7959 4 Biomechanics and Modeling in Mechanobiology 263 5 Springer cell mechanics Relationship between apical membrane elasticity and stress fiber organization in fibroblasts analyzed by fluorescence and atomuc force microscopy 2433/76827 Kawaguchi, Akiyoshi 1979/07/31 219 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 206 57 Institute for Chemical Research, Kyoto University Structural Changes of Polyethylene Single Crystal due to Electron Irradiation (Special Issue on Polymer Chemistry, XIV) 2433/77005 1982/11/15 362 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 347 60 Institute for Chemical Research, Kyoto University The Papers Published by the Staff Members of the Institute from July 1981 to June 1982 2433/126730 Kitagawa, Fumihiko 2010/12/15 A simple method for a chemical surface modification of poly(methyl methacrylate) (PMMA) microchips with amino-poly(ethyleneglycol) (PEG-NH(2)) by nucleophilic addition-elimination reaction was developed to improve the separation efficiency and analytical reproducibility in a microchip electrophoresis (MCE) analysis of biomolecules such as proteins and enantiomers. In our procedure, the PEG chains were robustly immobilized only by introducing an aqueous solution of PEG-NH(2) into the PMMA microchannel. The electroosmotic mobilities on the modified chips remained almost constant during 35 days with 37 runs without any recoating. The PEG-NH(2) modified chip provided a fast, reproducible, efficient MCE separation of proteins with a wide variety of isoelectric points within 15s. Furthermore, the application of the modified chip to affinity electrophoresis using bovine serum albumin gave a good chiral separation of amino acids. 1277 0731-7085 5 Journal of pharmaceutical and biomedical analysis 1272 53 2010 Elsevier B.V.

Amolops panhai, new species, differs from its congeners by the combination of: small body, males 31-34 mm, females 48-58 mm in snout-vent length; head narrower than long; tympanum distinct; vomerine teeth in short, oblique patches; first finger subequal to second; disc of first finger smaller than that of second, with circurnmarginal groove; no wide fringe of skin on third finger; toes fully webbed; outer metatarsal tubercle present; supratympanic fold present; dorsolateral fold indistinct; axillary gland present; horny spines on back, side of head and body, and chest absent; large tubercles on side of anus absent; glandular fold on ventral surface of tarsus absent; nuptial pad and paired gular pouches present in male; white band along the upper jaw extending to shoulder absent; larval dental formula 7(4-7)/3(1). This new species is the second anuran discovered which has a disjunct distribution around the Isthmus of Kra. 732 0289-0003 8 Zoological Science 727 23 Zoological Society of Japan Amolops A new species of Amolops from Thailand (Amphibia, Anura, Ranidae) 2433/77565 Kozuka, Hiromitsu 1994/10/31 224 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 209 72 Institute for Chemical Research, Kyoto University Preparation of Ag/TiO₂ Composite Films by the Sol-Gel Method (Commemoration Issue Dedicated to Professor Sumio Sakka On the Occasion of His Retirement) 2433/39694 Kondo, Y 2000/08/01 92 0021-8979 3 JOURNAL OF APPLIED PHYSICS 79 http://link.aip.org/link/?jap/88/79 88 AMER INST PHYSICS Wavelength dependence of photoreduction of Ag+ ions in glasses through the multiphoton process 2433/131855 Ganesan, Ponesakki 2010/12/01 Since anti-angiogenic therapy has becoming a promising approach in the prevention of cancer and related diseases, the present study was aimed to examine the anti-angiogenic effect of siphonaxanthin from green alga (Codium fragile) in cell culture model systems and ex vivo approaches using human umbilical vein endothelial cells (HUVECs) and rat aortic ring, respectively. Siphonaxanthin significantly suppressed HUVEC proliferation (p<0.05) at the concentration of 2.5 μM (50% as compared with control) and above, while the effect on chemotaxis was not significant. Siphonaxanthin exhibited strong inhibitory effect on HUVEC tube formation. It suppressed the formation of tube length by 44% at the concentration of 10 μM, while no tube formation was observed at 25 μM, suggesting that it could be due to the suppression of angiogenic mediators. The ex vivo angiogenesis assay exhibited reduced microvessel outgrowth in a dose dependent manner and the reduction was significant at more than 2.5 μM. Our results imply a new insight on the novel function of siphonaxanthin in preventing angiogenesis related diseases. 1144 0944-7113 14 Phytomedicine : international journal of phytotherapy and phytopharmacology 1140 17 Elsevier GmbH Angiogenesis Anti-angiogenic effect of siphonaxanthin from green alga, Codium fragile. 2433/134564 KASHINO, Genro 2010/10/30 The radioprotective effects of dimethyl sulfoxide (DMSO) have been known for many years, and the suppression of hydroxyl (OH) radicals induced by ionizing radiation has been thought to be the main cause of this effect. However, the DMSO concentration used was very high, and might be toxic, in earlier studies. In the present study, we administered a lower, non-toxic concentration (0.5%, i.e., 64 mM) of DMSO before irradiation and examined its radioprotective effects. Colony formation assay and micronucleus assay showed significant radioprotective effects in CHO, but not in xrs5, which is defective in the repair function of DNA double-strand breaks. The levels of phosphorylated H2AX and the formation of 53BP1 foci 15 minutes after irradiation, which might reflect initial DNA double-strand breaks, in DMSO-treated CHO cells were similar to those in non-treated cells, suggesting that the radioprotective effects were not attributable to the suppression of general indirect action in the lower concentration of DMSO. On the other hand, 2 hours after irradiation, the average number of 53BP1 foci, which might reflect residual DNA double-strand breaks, was significantly decreased in DMSO-treated CHO cells compared to non-treated cells. The results indicated that low concentration of DMSO exerts radioprotective effects through the facilitation of DNA double-strand break repair rather than through the suppression of indirect action. 740 0449-3060 6 Journal of Radiation Research 733 51 Japan Radiation Research Society An Alternative Mechanism for Radioprotection by Dimethyl Sulfoxide; Possible Facilitation of DNA Double-strand Break Repair 2433/39748 Urayama, K 2003/02/08 2910 0021-9606 6 JOURNAL OF CHEMICAL PHYSICS 2903 http://link.aip.org/link/?jcp/118/2903 118 AMER INST PHYSICS Volume transition of nematic gels in nematogenic solvents 2433/39750 Okuno, Y 2003/06/01 9860 0021-9606 21 JOURNAL OF CHEMICAL PHYSICS 9854 http://link.aip.org/link/?jcp/118/9854 118 AMER INST PHYSICS Influence of cross-linking density on volume phase transition of liquid crystalline gels in a nematogenic solvent 2433/93008 Higuchi, Shinya 2009/12/30 We studied the photoluminescence (PL) and energy-transfer processes in Eu^{3+} -doped GaN epitaxial films by means of microscopic PL imaging spectroscopy. Eu^{3+} -doped GaN epitaxial films exhibited blue luminescence due to bound-exciton recombinations in GaN host crystals and red luminescence due to intra-4f transitions of Eu^{3+} ions. We found an anticorrelation between the exciton and Eu^{3+} PL intensities in space-resolved PL images, indicating that energy transfer from GaN crystals to Eu^{3+} ions determines the Eu^{3+} luminescence intensity. PL and PL excitation spectra showed that efficient Eu^{3+} luminescence is caused by two different excitation processes: energy transfer from the low-energy charge-transfer (CT) states to Eu^{3+} ions or from the delocalized states above the band edge of GaN crystals to Eu^{3+} ions. The energy-transfer process from the CT state to Eu^{3+} ions dominates the Eu^{3+} luminescence. 1098-0121 3 Physical Review B 81 American Physical Society Luminescence and energy-transfer mechanisms in Eu^{3+} -doped GaN epitaxial films 2433/93438 Mimura, Tatsuya 2008/10/03 PURPOSE: To isolate fibroblast precursors from rabbit corneal stroma using a sphere-forming assay, to engineer corneal stroma with the precursors and gelatin, and to establish the therapeutic application of precursors in a rabbit corneal stroma. METHODS: In the in vitro study, a sphere-forming assay was performed to produce precursors from rabbit corneal stroma. Corneal stroma was engineered by cultivating precursors in porous gelatin for one week. In the in vivo study, the engineered corneal stromal sheet with precursors (precursor/gelatin group) or with fibroblasts (fibroblast /gelatin group) or without cells (gelatin group) was transplanted to a pocket of rabbit corneal stroma. Gene expression and extracellular matrix production were examined immunohistochemically in each group one week and four weeks after surgery. RESULTS: In the in vitro study, cells in the spheres were BrdU-positive, and their progeny were keratocan-positive. The study also showed that the corneas transplanted with a porous gelatin sheet did not show any opacity four weeks after transplantation in any group. In the gelatin sheet of the precursor/gelatin group, a more intense expression of type I collagen was observed relative to the other two groups four weeks after the surgery. CONCLUSIONS: Our findings demonstrate that the transplantation of fibroblast precursors combined with gelatin hydrogel into the corneal stroma is a possible treatment strategy for corneal stromal regeneration. 1828 1090-0535 Molecular vision 1819 http://www.molvis.org/molvis/v14/a215 14 Molecular Vision Tissue engineering of corneal stroma with rabbit fibroblast precursors and gelatin hydrogels. 2433/108604 Sato, Masanori 2001/08/30 A unique scale worm Hesperonoe hwanghaienssi Uschakov and Wu, 1959 (Polychaeta: Polynoidae) was collected from tidal flats in Japan and is described here taxonomically as the second record of this species since its original description from Chinese specimens. Some morphological features of our specimens differed slightly from the original description of this species. Marked differences in growth pattern, morphology of elytra and microhabitat were demonstrated between juveniles (1.8 mm or less in body width) and adults (1.9 mm or more). We estimated the outline of the life history of the scale worm by sampling it in various seasons. The scale worm was commensal with the burrowing shrimp Upogebia major. Juveniles of the scale worm were commonly attached to the ventral or lateral surface of the thorax or abdomen of the host throughout May to September in Isahaya Bay in the Ariake Sea, Kyushu. In July 1998, 89% of the host shrimps were infested by the scale worm. Several juveniles (maximum: 7) of the scale worm often aggregated on a host body, with no adults found on the hosts. The adults were collected from sediment samples. These results suggest that the juveniles mainly live on the surface of the host body and that they later detach themselves from the host body and live freely on the inner surface of the burrow of the host. 991 0289-0003 7 Zoological Science 981 18 Zoological Society of Japan Taxonomy and Life History of the Scale Worm Hesperonoe hwanghaiensis (Polychaeta: Polynoidae), newly Recorded in Japan, with Special Reference to Commensalism to a Burrowing Shrimp, Upogebia major 2433/108607 Kobayashi, Ako 2001/07/30 The ascidian embryo has been long thought to show a mosaic mode of development. However, recent studies revealed significance of cell-cell communication during cleavage stages of embryogenesis. FGF and BMP signalings play critical roles in determination of cell types. Little is, however, known about regulation of competence of cells to the signals. Here we report the isolation of ascidian smad genes; Hrsmad4 which encodes a homolog of smad4 of vertebrates, Hrsmad6/7 which encodes a homologous gene of smad 6 and smad7 of vertebrates, and Hrsmad2/3 which encodes a homolog of smad2 and smad3 of vertebrates. The mRNAs of the isolated smad family genes were maternally inherited in egg and early embryos. While Hrsmad4 and Hrsmad6/7 RNAs distributed broadly in the early embryos, Hrsmad2/3 RNA was preferentially accumulated in the animal hemisphere. 842 0289-0003 6 Zoological Science 833 18 Zoological Society of Japan Expression Patterns of Smad Family Members during Embryogenesis of the Ascidian Halocynthia roretzi 2433/109886 Ogawa, Hiroki 2009/08/30 We performed time-resolved specular and off-specular neutron reflectivity measurements on blend thin films 42 and 98 nm thick of deuterated polystyrene and poly(vinyl methyl ether) during dewetting process induced by the phase separation in two phase region using a time-of-flight neutron reflectometer. In the specular measurements we found that the phase separation directed to the depth direction occurred near the air interface as well as near the Si substrate during the incubation period before dewetting. In addition we also found that the phase separation occurred asymmetrically at the two interfaces and inhomogeneously in the film plane, showing that the dewetting was induced by the composition fluctuation mechanism. Off-specular reflectivity was analyzed, for the first time, to evaluate kinetics of structure formation in the film plane during the dewetting process. We found in the analysis that the droplets formation in micrometer scale occurred in the late stage of dewetting. 0021-9606 10 JOURNAL OF CHEMICAL PHYSICS http://link.aip.org/link/JCPSA6/v131/i10/p104907/s1 131 American Institute of Physics Time-resolved specular and off-specular neutron reflectivity measurements on deuterated polystyrene and poly(vinyl methyl ether) blend thin films during dewetting process 2433/158364 Etou, Junji 2011/04/07 We have investigated the mechanism of enhanced absorption intensities of vibrational bands of adsorbates on copper meshes with subwavelength holes by measuring and simulating temporal profiles of infrared pulses transmitted through the meshes. As reported previously [Williams et al., J. Phys. Chem. B, 2003, 107, 11871], the absorption intensities of CH stretching bands of alkanethiolate adsorbed on the mesh increase substantially with decreasing hole size. The enhancements of absorption intensities are associated with temporal delays of infrared pulses transmitted through the mesh. Finite difference time domain calculations reproduce the observed pulse delays as a function of hole size. These facts indicate that the delays of transmitted pulses are not caused by coupling of infrared radiation to surface plasmon polaritons propagating on the front and rear surfaces of the mesh, but they are caused by the reduction in group velocity owing to coupling to waveguide modes of mesh holes. Consequently, the strong enhancements of the absorption intensities are attributed to adsorbates inside the holes rather than to those on the mesh surfaces that have been proposed previously. 5823 1463-9076 13 Physical chemistry chemical physics : PCCP 5817 13 Royal Society of Chemistry Mechanism of enhancement in absorbance of vibrational bands of adsorbates at a metal mesh with subwavelength hole arrays. 2433/86501 Ohde, Yoshihito 1974/09/24 Kyoto University ポリエチレン繊維の異方構造とそれに関連した性質 Anisotropic Structure of Polyethylene Fiber and Its Related Properties 2433/160227 Nishida, Koji 2011/11/23 In situ observation of the formation process of a mesophase of isotactic polypropylene is reported from a structural point of view. A very rapid transformation from the molten state to the mesophase has, for many years, made in situ observation difficult. In the present study, a rapid temperature jump and high-flux synchrotron radiation X-ray scattering techniques were combined effectively to observe this transformation. Fast time-resolved wide-angle X-ray diffraction during rapid cooling clearly shows the time evolution of the transformation from the molten state to the mesophase. The transformation proceeded very quickly in a narrow temperature range below ca 35 °C. Furthermore, the transformation was accompanied by instantaneous density fluctuations throughout the system, as visualized by microscopic observations. These observations suggest that the mesophase formation proceeds similarly to spinodal decomposition. 101 0032-3896 1 Polymer Journal 95 44 Nature Publishing Group isotactic polypropylene (iPP) In situ observations of the mesophase formation of isotactic polypropylene—A fast time-resolved X-ray diffraction study 2433/160660 Rode, S. 2011/06/29 A key issue for high-resolution frequency-modulation atomic force microscopy imaging in liquids is minimizing the frequency noise, which requires a detailed analysis of the corresponding noise contributions. In this paper, we present a detailed description for modifying a commercial atomic force microscope (Bruker MultiMode V with Nanoscope V controller), aiming at atomic-resolution frequency-modulation imaging in ambient and in liquid environment. Care was taken to maintain the AFMs original stability and ease of operation. The new system builds upon an optimized light source, a new photodiode and an entirely new amplifier. Moreover, we introduce a home-built liquid cell and sample holder as well as a temperature-stabilized isolation chamber dedicated to low-noise imaging in liquids. The success of these modifications is measured by the reduction in the deflection sensor noise density from initially 100 fm /[√Hz] to around 10 fm /[√Hz] after modification. The performance of our instrument is demonstrated by atomically resolved images of calcite taken under liquid conditions. 0034-6748 7 REVIEW OF SCIENTIFIC INSTRUMENTS http://link.aip.org/link/?rsi/82/073703 82 American Institute of Physics amplifiers Modification of a commercial atomic force microscopy for low-noise, high-resolution frequency-modulation imaging in liquid environment 2433/173088 Masunaga, Shin-Ichiro 2013/02/27 Labeling of proliferating (P) cells in mice bearing EL4 tumors was achieved by continuous administration of 5-bromo-2'-deoxyuridine (BrdU). Tumors were irradiated with γ-rays at 1 h after pimonidazole administration followed by caffeine or wortmannin treatment. Twenty-four hours later, assessment of the responses of quiescent (Q) and total (= P + Q) cell populations were based on the frequencies of micronucleation and apoptosis using immunofluorescence staining for BrdU. The response of the pimonidazole-unlabeled tumor cell fractions was assessed by means of apoptosis frequency using immunofluorescence staining for pimonidazole. The pimonidazole-unlabeled cell fraction showed significantly enhanced radio-sensitivity compared with the whole cell fraction more remarkably in Q cells than total cells. However, a significantly greater decrease in radio-sensitivity in the pimonidazole-unlabeled than the whole cell fraction, evaluated using an assay performed 24 hours after irradiation, was more clearly observed in Q cells than total cells. In both the pimonidazole-unlabeled and the whole cell fractions, wortmannin efficiently suppressed the reduction in sensitivity due to delayed assay. Wortmannin combined with γ-ray irradiation is useful for suppressing the recovery from radiation-induced damage especially in the pimonidazole-unlabeled cell fraction within the total and Q tumor cell populations. 229 0449-3060 2 Journal of radiation research 221 54 Oxford University Press Quiescent cell Wortmannin efficiently suppresses the recovery from radiation-induced damage in pimonidazole-unlabeled quiescent tumor cell population. 2433/173350 Miyao, Masashi 2013/02/27 [Background]The bile canaliculus is the smallest and first biliary channel and is formed by two or three adjacent hepatocytes. Previous studies of chronic cholangiopathies such as primary sclerosing cholangitis have focused on the bile ductules. However, little is known about the pathological alterations in bile canaliculi in the early phase of cholangiopathies. [Aim]To characterize the bile canalicular morphology in the early phase of sclerosing cholangitis we used 3,5-diethoxycarbonyl-1,4-dihydrocollidine-induced mouse model of sclerosing cholangitis. [Methods]Mice were fed a diet with 3,5-diethoxycarbonyl-1,4-dihydrocollidine (0.1%). Serum biochemical, histological, immunohistochemical, and electron microscopic analyses were performed 1, 2, 4, and 7 days after feeding. [Results]All experimental groups showed significantly increased serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase levels. From day 1, bile canalicular abnormalities such as dilatation and meandering and loss of microvilli were observed. After bile canalicular abnormalities had appeared, substantial infiltration of inflammatory cells was observed amongst the necrotic cells and periductal region. After these inflammatory changes, cholangiocytes proliferated in the portal area and formed ductular reactions. Finally, periductal fibrosis appeared. [Conclusion]This study provides novel evidence of the occurrence of bile canalicular abnormalities during the early phase of sclerosing cholangitis. 225 1590-8658 3 Digestive and liver disease 216 45 Elsevier Ltd.

In the synthetic route starting from nickel chloride as a nickel precursor, trimethylene oxide acts as a gelation initiator to increase pH in a reaction solution. In addition, poly(acrylic acid) plays a double role as a phase separation inducer and as a co-constituent with nickel hydroxide to comprise continuous gel skeletons in the micrometer range. As a result, obtained xerogels possess well-defined macropores evidenced by microscopy observation and mercury porosimetry. Subsequent heat-treatment in air led to the crystallization of NiO at 300 °C, while calcination under argon flow brought about the formation of nickel/carbon (Ni/C) composites with hierarchical pores and large specific surface area at temperatures higher than 300 °C. This is the first report on the preparation of rigid monolithic xerogels and metal/carbon composite with well-defined macropores based on a metal salt precursor containing "divalent" cation. 70 1387-1811 Microporous and Mesoporous Materials 64 176 Elsevier Inc Hierarchically porous nickel/carbon composite monoliths prepared by sol–gel method from an ionic precursor 2433/75006 Okazaki, Morio 1975/05/23 Kyoto University 乾燥における移動物性と乾燥特性に関する研究 Transport Properties in Drying Process and Drying Characteristics 2433/70026 Fujita, Satoshi 2009/01/23 Kyoto University Stem cell 幹細胞の挙動を制御する微小環境の作成およびその応用 Development and Application of Microenvironment for Regulation of Stem Cell Behaviors 2433/126814 Uriu, Yoshitsugu 2010/09/24 Kyoto University Ca2+ channel 神経伝達に関わるCa2+チャネル複合体の生化学・生物物理学的解明 Biochemical and biophysical characterization of Ca2+ channel complexes in neurotransmission 2433/126817 Oba, Masatoshi 2010/09/24 Kyoto University MEMS 縦方向に集積化されたMEMSデバイス作製の研究 STUDIES ON THE FABRICATION OF VERTICAL INTEGRATED MEMS DEVICES 2433/120945 葛西, 裕 2010/05/24 京都大学 polysaccharide 多糖類由来電解質膜の溶媒透過挙動とプロトン伝導特性 2433/108363 Koshiba, Taichi 2010/03/23 Kyoto University タバコ培養細胞のホウ素欠乏応答に関する研究 Studies on Responses of Tobacco Cells to Boron Deprivation 2433/129192 齋藤, 武士 2004/04/01 802 0386-412X B 京都大学防災研究所年報.

Some important structures discovered and their mechanisms for improving the cyclability were discussed as follows. In Chapter 1, the electrode structure of Sn electrodes was discussed, where the theoretical capacity of Li4.4Sn was attained. Weak adhesion of Sn to the Cu foil prevented the powdered Sn electrodes prepared by a conventional slurry-coating process from providing the theoretical capacity of Sn metal from the initial cycle, where the Sn powder peeled off the Cu foil to be disconnected from the foil in electronic conductivity. The electrodeposition process improved the interface adhesion between Sn and Cu foil. The electrodeposited Sn film sticks tightly to the Cu foil after forming the intermediate Cu6Sn5 layer, and it reacts with lithium to the theoretical capacity of Li4.4Sn under the full charge-discharge condition with small irreversible capacity. The initial discharge capacity was 2.5 times as large as that of the graphite. In Chapter 2, the advanced phase structure of the electrodeposited Sn film was discussed, which improved the film in cyclability without a large loss of capacity. The Sn film-Cu foil interface adhesion was still weaker to be delaminated from the Cu foil. Also, the Sn film was pulverized and passivated by electrolyte reduction products. The film was disconnected from the Cu foil in electronic conductivity during the initial cycle and could not continue to react with lithium. The stepwise composition-graded phase structure improved the film in the interface adhesion and active material chemistry to provide better cyclability under the full charge-discharge condition without large sacrifice of their volumetric capacity. The phase structure consists of the Cu6Sn5 and Cu3Sn phases, where Cu6Sn5 phase is the active material with less volume change and electrolyte-reactivity and the Cu3Sn phase enhances the adhesion between the Cu6Sn5 phase and Cu foil. The annealing process formed the stepwise composition-graded phase structure, and the annealing condition controlled the structure to be optimized for better cyclability. In Chapter 3, the advanced microstructure of the electrodeposited Sn film was discussed, which improved the film with the stepwise composition-graded phase structure in cyclability. The annealed rough-surfaced Sn electrode showed better cyclability than the annealed flat-surfaced Sn electrode, even though they had the same stepwise composition-graded phase structure. The micro-columnar structure of the film improved the film in the interface adhesion. The structure self-organizes on the rough surface of the Cu foil during the first charge-discharge cycle. The film is divided into columns of about 10μm square by gaps to accommodate swelled film with much reduced internal stress and strain during the following charge, resulting in less pulverization and enhanced adhesion of the film to the foil. The wavy surface profile of the foil and moderate ductility of the film are critical factors to self-organize the micro-columnar structure of the film during charge and discharge. Close cyclability to typical graphite-anode cells was available for the small cell using the annealed rough-surfaced Sn electrode for 20 cycles. In Chapter 4, the electro co-deposited 79.8Sn-20.2Co alloy film was examined for electrochemical and structural properties, and the feasibility of formation of the microstructure was discussed. The micro-island structure was self-organized on the rough surface of the Cu foil during the first charge-discharge cycle, which is similar to the micro-columnar structure in mechanism for improving the cyclability as well as in the shape. As a result, the Sn-Co alloy electrode offered the same capacity at the 20th cycle as the initial capacity of about 60% of the theoretical capacity of Li4.4Sn. The mechanical properties of the film such as ductility and brittleness give another key for formation of the microstructure, in addition to the rough surface of the current collector foil. In Chapter 5, the anomalous cycle performance of the 79.8Sn-20.2Co alloy electrode was discussed in terms of morphology and phase structure of the film. The film showed four-step change in discharge capacity, which depends on the two-stage phase transformation and morphological change of the film. The film is transformed from the amorphous phase to a new phase with forming fcc-Co particles. The new phase is a key to stable reaction of the Sn-Co film with lithium. Although the new phase initially shows smaller capacity than the amorphous phase, the enlarged surface area of the film activates a new reaction of the new phase to increase capacity. As a result, the new phase provides as large capacity as the amorphous phase. In Chapter 6, the electro co-deposited 92.1Sn-7.9Co alloy film with the microstructure was examined for electrochemical and structural properties, which comprised the new phase of the 79.8Sn-20.2Co alloy film as electrodeposited, and the mechanism of the reaction stability of the new phase was discussed. The 92.1Sn-7.9Co alloy film had the nano-composite phase structure, where the less lithium-active crystalline phase surrounds the amorphous phase to accommodate volume change of the amorphous phase and prevent it from deteriorating, resulting in stable reaction of the amorphous phase with lithium to provide constant capacity. On the other hand, the morphological and phase structural changes of the film improve Li+ diffusion through the film-electrolyte interface, in the film, and in the amorphous phase to increase capacity. As a result, under the full charge-discharge condition, the 92.1Sn-7.9Co alloy film showed monotonous increase in discharge capacity from 663 mAh/g at the 1st cycle to 769 mAh/g at the 20th cycle, which is 77% of the theoretical capacity of Li4.4Sn. Since the phase transformation of the 79.8Sn-20.2Co alloy film caused deterioration of the adhesion between the film and current collector to degrade the cyclability of the film, the phase structure of the 92.1Sn-7.9Co film gives better cyclability when it is prepared in advance of the reaction. There should be still room for further stable cyclability in Sn-Co alloy films. For example, adding a third atom to the film composition may enhance the stability of the reaction of the amorphous phase. Not only electro co-deposition but various thin-filming processes will be proposed to control a three-or-more-component system. However, the adhesion of the film and Cu foil is the crucial factor for the stable cyclability, and the microstructure such as the micro-columnar structure and micro-island structure is the most fundamental and effective in enhancing the adhesion. The micro-columnar structure has been applied for Si and Ge systems and examined for its self-organization mechanism, cyclability, and other electrochemical properties. Some of the results have already reported [67-68]. The advanced lithium ion batteries of group 14 elements with the microstructure may become commercially available in near future. Also, the microstructure should be formed on the flat-surfaced foil with holes in the same stress-concentration mechanism as the rough-surfaced foil. Since the rough-surfaced Cu foil is formed by Cu electrodeposition, there are limitations to control the surface profile. However, the holes can be punched at intervals of a-micrometer-order by using physical processes such as a femto-second laser, resulting in formation of further size-controlled microstructure. Issues of the laser process are beam concentration to make holes of less than 10μm in diameter and long work time. A suitable grating should be a key to overcome the issues and find another potential of the microstructure.

Among them, intramolecular FRET biosensors have been increasingly used due to their high sensitivity and user-friendliness. Time-consuming optimizations by trial and error, however, obstructed the development of intramolecular FRET biosensors. Here we report an optimized backbone for rapid development of highly sensitive intramolecular FRET biosensors. The key concept is to exclude the "orientation-dependent" FRET and to render the biosensors completely "distance-dependent" with a long, flexible linker. We optimized a pair of fluorescent proteins for distance-dependent biosensors, and then developed a long, flexible linker ranging from 116 to 244 amino acids in length, which reduced the basal FRET signal and thereby increased the gain of the FRET biosensors. Computational simulations provided insight into the mechanisms by which this optimized system was the rational strategy for intramolecular FRET biosensors. With this backbone system, we improved previously reported FRET biosensors of PKA, ERK, JNK, EGFR/Abl, Ras, and Rac1. Furthermore, this backbone enabled us to develop novel FRET biosensors for several kinases of RSK, S6K, Akt, and PKC and to perform quantitative evaluation of kinase inhibitors in living cells. 4656 1059-1524 23 Molecular biology of the cell 4647 22 American Society for Cell Biology Development of an optimized backbone of FRET biosensors for kinases and GTPases. 2433/77823 Kimoto, Tsunenobu 1996/03/23 Kyoto University α-Sicのステップ防御エピタキシャル成長とデバイス応用 Step-Controlled Epitaxial Growth of α-Sic and Device Applications 2433/152300 Ratanavaraporn, Juthamas 2011/12/30 The objective of this study is to investigate the effect of local inflammation suppression on the bone regeneration. Gelatin hydrogels incorporating mixed immunosuppressive triptolide-micelles and bone morphogenic protein-2 (BMP-2) were prepared. The controlled release of both the triptolide and BMP-2 from the hydrogels was observed under in vitro and in vivo conditions. When either J774.1 macrophage-like or MC3T3-E1 osteoblastic cells were cultured in the hydrogels incorporating mixed 2.5, 5 or 10 mg of triptolide-micelles and BMP-2, the expression level of pro- and anti-inflammatory cytokines including interleukin (IL)-6 and IL-10 was down-regulated, but the alkaline phosphatase (ALP) activity was promoted compared with those of hydrogels incorporating BMP-2 without triptolide-micelles. When implanted into a critical-sized bone defect of rats, the hydrogels incorporating mixed 2.5 or 5 mg of triptolide-micelles and BMP-2 showed significantly lower number of neutrophils, lymphocytes, macrophages or dendritic and mast cells infiltrated into the defect, and lower expression level of IL-6, TNF-α, and IL-10 than those incorporating BMP-2 without triptolide-micelles. The reduced local inflammation responses at the defects implanted with the hydrogels incorporating mixed 2.5 or 5 mg of triptolide-micelles and BMP-2 subsequently enhanced the bone regeneration thereat. It is concluded that the proper local modulation of inflammation responses is a promising way to achieve the enhanced bone regeneration. 316 0142-9612 1 Biomaterials 304 33 Elsevier Ltd.

To identify the properties of these reservoirs, four SIV239-infected Rhesus macaques were treated with combined antiretroviral therapy (cART) for 1 year. While plasma viral RNA (vRNA) was effectively suppressed, a systemic analysis revealed that vRNA was distributed in the following order: lymphatic tissues>lungs and intestine>other tissues. Histochemistry yielded no cells with viral signals. To increase the chance of detection, two additional SIV-infected animals were treated and analyzed on Day 10 after the cessation of cART. These animals exhibited similar vRNA distribution patterns to the former animals, and immunohistochemistry revealed Nef-positive T lymphocytes predominantly in the follicles of mesenteric lymph nodes (MLNs). These data suggest that lymphatic tissues, including MLNs, contain major cellular reservoirs that cause rebound of plasma viremia upon cessation of therapy. 118 1096-0341 2 Virology 107 423 Elsevier B.V.

However, it remains unknown how Arf6 contributes to cytokinesis. Here, we demonstrate that Arf6 directly interacts with mitotic kinesin-like protein 1 (MKLP1), a Flemming body-localizing protein essential for cytokinesis. The crystal structure of the Arf6-MKLP1 complex reveals that MKLP1 forms a homodimer flanked by two Arf6 molecules, forming a 2:2 heterotetramer containing an extended β-sheet composed of 22 β-strands that spans the entire heterotetramer, suitable for interaction with a concave membrane surface at the cleavage furrow. We show that, during cytokinesis, Arf6 is first accumulated around the cleavage furrow and, prior to abscission, recruited onto the Flemming body via interaction with MKLP1. We also show by structure-based mutagenesis and siRNA-mediated knockdowns that the complex formation is required for completion of cytokinesis. A model based on these results suggests that the Arf6-MKLP1 complex plays a crucial role in cytokinesis by connecting the microtubule bundle and membranes at the cleavage plane. 正常な細胞分裂に不可欠なタンパク質の機能と構造を解明. 京都大学プレスリリース. 2012-05-31. 2603 1460-2075 11 The EMBO journal 2590 http://www.nature.com/emboj/journal/v31/n11/full/emboj201289a.html 31 Nature Publishing Group Arf6 Structural basis for Arf6-MKLP1 complex formation on the Flemming body responsible for cytokinesis 2433/65649 1995/02/27 82 1342-0321 ICR annual report 62 1 Institute for Chemical Research, Kyoto University PUBLICATIONS 2433/65683 1995/02/27 1342-0321 ICR annual report 1 Institute for Chemical Research, Kyoto University ICR ANNUAL REPORT 1994(Volume 1) 2433/157115 Nomura, Norimichi 1998/03/23 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University 海洋性超好熱古細菌Aeropyrum pernixにおけるrRNAイントロンの分子構造と機能に関する研究 Studies on structure and function of the rRNA introns in the hyperthermophilic archaeon Aeropyrum pernix 2433/157131 Sone, Takefumi 1999/03/23 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University 雌雄異株苔類ゼニゴケの性決定・分化機構解明にむけた分子細胞学的解析 Molecular cytological analyses toward the clarification of the sex determination and differentiation mechanisms in a dioecious liverwort, Marchantia polymorpha L 2433/76313 1970/03/28 662 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 628 47 Institute for Chemical Research, Kyoto University Abstracts of the Papers Published in Other Journals by the Staff members of the Institute from July, 1968 to June, 1969 2433/86440 Fukuoka, Hiroshi 1992/03/23 Kyoto University 高速高圧リングせん断試験における粒状体材料のマサツ角の変化 : せん断中の粒子配向・配列・破砕の影響 Variation of the Friction Angle of Granular Materials in the High-Speed High-Stress Ring Shear Apparatus-Influence of Re-orientation,Alignment and Crushing of Grains during Shear- 2433/86417 Shimobayashi, Norimasa 1990/03/23 Kyoto University 高温透過型電子顕微鏡による Ca-poor 輝石の相転移のその場観察 High Temperature Transmission Electron Microscopy of the Polymorphic Phase Transformation in Ca-poor Pyroxenes 2433/76509 1974/03/30 415 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 377 51 Institute for Chemical Research, Kyoto University Abstracts of the Papers Published by the Staff Members of the Institute from July, 1971 to June, 1972 2433/77077 Ishikawa, Akira 1984/11/25 285 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 251 62 Institute for Chemical Research, Kyoto University Dielectric Study of Some Ion-Exchange Resins 2433/53219 1996/08/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 246 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 211 83 Wood Research Institute, Kyoto University Abstracts 2433/53167 1999/09/30 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 85 0049-7916 Wood research : bulletin of the Wood Research Institute Kyoto University 53 86 Wood Research Institute, Kyoto University Abstracts 2433/77416 1992/02/15 616 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 587 69 Institute for Chemical Research, Kyoto University The Papers Published by the Staff Member of the Institute from July 1990 to June 1991 2433/151700 Okuyama, Hiroshi 2011/10/30 The scanning tunnelling microscope (STM) has been a valuable tool in surface science for the study of structures and electronic states of metal surfaces. The recent advance of STM as a state-of-the-art technique to probe and manipulate individual molecules has made it possible to investigate molecular dynamics and chemical reactions at the surface in a single-molecule limit. In this review paper, we present an overview of our recent work of H-bond imaging, manipulating and engineering at a metal surface. From individual water molecules, a variety of H-bonded structures including water clusters, hydroxyl clusters and water–hydroxyl complexes are assembled on Cu(1 1 0), whose properties and dynamics are studied in real space in collaboration with density-functional-theory calculations. 0022-3727 46 Journal of Physics D: Applied Physics 44 IOP Publishing Hydrogen-bond imaging and engineering with a scanning tunnelling microscope 2433/77968 Iwamoto, Sohei 2009/03/23 Kyoto University Finite element analysis 合金化溶融亜鉛めっき鋼板コーティング層の引張負荷ひずみ下での多重破断及び界面はく離解析 Analysis of multiple cracking and interfacial debonding of the galvannealed coating layer under applied tensile strain 2433/78004 上田, 雅也 2009/03/23 京都大学 半極性 半極性GaNバルク基板上へのInGaN量子構造の成長と偏光物性 2433/65251 2000/02/28 1342-0321 ICR annual report 6 Institute for Chemical Research, Kyoto University ICR ANNUAL REPORT 1999(Volume 6) 2433/78003 Miki, Takafumi 2009/03/23 Kyoto University Ca2+チャネル 電位依存性Ca2+チャネル分子複合体による神経機能ダイナミクスの解明 Elucidation of dynamics of neuronal functions by molecular analyses of Ca2+ channel complexes 2433/112092 志賀, 宗俊 1961/01/30 1) Findings of tuberculous bacilli in caseous lesions : Tuberculous bacilli were found in fresh caseou s lesions and cavities, much of which were found especially in leucocytes, epithelioid cells and caseous necrotic masses as well as in caseous lesions of other tissues. However, it is very rare to be found growing in a dead mass or in a condition like on a artificial culture medium. As for the focus and types of tuberculous bacilli, most of them were ordinary type and there were little atypical types and granular forms. Administr a tion of anti-tuberculous drugs of doses illustrated in this report did not give much difference in types and forms between the treated group and the control group. 2) Tuberculous bacilli found adjascent to caseous lesions There were not so many bacilli found both in t h e control and treated groups. In more than half of cases were found no bacilli, if present, the number of bacilli were two to three or there-about and no significant difference was found between these two groups. 3) Tuberculous bacilli in tubercles per se : Most cases were negative for presence o f bacilli both in the treated and control groups. No bacilli was found in all cases of No. 4 and 5 groups which were administered relatively large doses of anti-tuberculous drugs. The incidence of presence o f tuberculous bacilli in caseous lesions, area adjascent to caseous lesions and tubercle were 72.2 per cent, 38.9 per cent and 45 per cent respectively, in control group and 72 per cent, 45.7 per cent and 53.5 per cent in the treated group, which were much higher than in published data. Thus the effects of doses of anti-tuberculous drugs upon tuberculous bacilli were minimal. 4) Relatively many bacilli were found in the ducts and not so many in the epithelia and sub-epithelial tissue and about two times of bacilli were found in the interstitial tissue as much as found in the ducts, epithelia and sub-epithelial tissues. Thus it was found that the forms of invasions, rate of e x istence of bacilli and the amount of bacilli corresponded with each other. In addition, the bacilli were found most in the ducts in cases of both ductal and interstitial disseminations. 252 0018-1994 2 泌尿器科紀要 240 7 泌尿器科紀要刊行会 Effects of Anti-tuberculous Drugs upon Tuberculous Bacilli in Epididymis by Means of Fluororescence Microscope (Yazaki) 抗結核剤(Streptomycin,PAS,INAH)を使用せる畢上体内結核菌の螢光法(矢崎氏)に依る所見に就いて 2433/150729 Yamaguchi, Tetsuji 2001/03/23 Kyoto University アクチニド元素と核分裂生成物の花崗岩内拡散に対する表面拡散の寄与に関する研究 STUDY ON CONTRIBUTION OF SURFACE DIFFUSION ON MASS TRANSFER OF ACTINIDES AND FISSION PRODUCTS IN GRANITE 2433/157608 Igarashi, Ryuji 2012/03/26 Kyoto University 生体内計測 高偏極スピンの磁気共鳴を用いた選択的生体内計測 In vivo selective detection of highly polarized spin using MR 2433/86257 Imae, Naoya 1994/03/23 要旨ファイルのタイトルは"Peritectic reactions in Mg-O-H and Fe-S-H systems in the primordial solar nebula" Kyoto University 原始太陽系星雲におけるMg-Si-O-H系とFe-S-H系の包晶反応 Peritectic reactions in Mg-Si-O-H and Fe-S-H systems in the primordial solar nebula 2433/74581 Okihara, Takumi 1991/06/29 Kyoto University ポリオレフィン薄膜上での長鎖化合物の結晶化挙動 Crystallization Behavior of Long Chain Compounds on Polyolefin Thin Films 2433/86295 Tamada, Osamu 1980/09/24 Kyoto University 珪酸塩鉱物におけるイオン性結合エネルギーと原子の実効電荷 The Ionic Bonding Energy and Effective Atomic Charge of Several Silicate Minerals 2433/138258 Kawamura, Mitsunori 1971/07/23 Kyoto University ソイルセメントの内部組織と力学的性質に関する基礎的研究 FUNDAMENTAL STUDIES ON THE FABRIC OF SOIL-CEMENT MIXTURE AND ITS MECHANICAL PROPERTIES 2433/160880 Takai, Ken 1997/03/24 本文データは平成22年度国立国会図書館の学位論文(博士)のデジタル化実施により作成された画像ファイルを基にpdf変換したものである Kyoto University 海洋性超好熱細菌Rhodothermus obamensisにおけるホスホエノルピルビン酸カルボキシラーゼ(PEPC)の耐熱機構に関する研究 Study on Thermostabilization Mechanisms of Phosphoenolpyruvate Carboxylase(PEPC)from an Extremely Thermophilic Bacterium Rhodothermus obamensis 2433/163452 Nakayama, Minoru 2011/07/30 The peroxisome biogenesis disorders (PBDs) are currently difficult-to-treat multiple-organ dysfunction disorders that result from the defective biogenesis of peroxisomes. Genes encoding Peroxins, which are required for peroxisome biogenesis or functions, are known causative genes of PBDs. The human peroxin genes PEX3 or PEX16 are required for peroxisomal membrane protein targeting, and their mutations cause Zellweger syndrome, a class of PBDs. Lack of understanding about the pathogenesis of Zellweger syndrome has hindered the development of effective treatments. Here, we developed potential Drosophila models for Zellweger syndrome, in which the Drosophila pex3 or pex16 gene was disrupted. As found in Zellweger syndrome patients, peroxisomes were not observed in the homozygous Drosophila pex3 mutant, which was larval lethal. However, the pex16 homozygote lacking its maternal contribution was viable and still maintained a small number of peroxisome-like granules, even though PEX16 is essential for the biosynthesis of peroxisomes in humans. These results suggest that the requirements for pex3 and pex16 in peroxisome biosynthesis in Drosophila are different, and the role of PEX16 orthologs may have diverged between mammals and Drosophila. The phenotypes of our Zellweger syndrome model flies, such as larval lethality in pex3, and reduced size, shortened longevity, locomotion defects, and abnormal lipid metabolisms in pex16, were reminiscent of symptoms of this disorder, although the Drosophila pex16 mutant does not recapitulate the infant death of Zellweger syndrome. Furthermore, pex16 mutants showed male-specific sterility that resulted from the arrest of spermatocyte maturation. pex16 expressed in somatic cyst cells but not germline cells had an essential role in the maturation of male germline cells, suggesting that peroxisome-dependent signals in somatic cyst cells could contribute to the progression of male germ-cell maturation. These potential Drosophila models for Zellweger syndrome should contribute to our understanding of its pathology. 1932-6203 8 PLOS ONE 6 Public Library of Science Drosophila Carrying Pex3 or Pex16 Mutations Are Models of Zellweger Syndrome That Reflect Its Symptoms Associated with the Absence of Peroxisomes 2433/166071 Kominami, Katsuya 2012/11/21 [Background]: Activation of caspases is crucial for the execution of apoptosis. Although the caspase cascade associated with activation of the initiator caspase-8 (CASP8) has been investigated in molecular and biochemical detail, the dynamics of CASP8 activation are not fully understood. [Methodology/Principal Findings]: We have established a biosensor based on fluorescence resonance energy transfer (FRET) for visualizing apoptotic signals associated with CASP8 activation at the single-cell level. Our dual FRET (dual-FRET) system, comprising a triple fusion fluorescent protein, enabled us to simultaneously monitor the activation of CASP8 and its downstream effector, caspase-3 (CASP3) in single live cells. With the dual-FRET-based biosensor, we detected distinct activation patterns of CASP8 and CASP3 in response to various apoptotic stimuli in mammalian cells, resulting in the positive feedback amplification of CASP8 activation. We reproduced these observations by in vitro reconstitution of the cascade, with a recombinant protein mixture that included procaspases. Furthermore, using a plasma membrane-bound FRET-based biosensor, we captured the spatiotemporal dynamics of CASP8 activation by the diffusion process, suggesting the focal activation of CASP8 is sufficient to propagate apoptotic signals through death receptors. [Conclusions]: Our new FRET-based system visualized the activation process of both initiator and effector caspases in a single apoptotic cell and also elucidated the necessity of an amplification loop for full activation of CASP8. 1932-6203 11 PloS one 7 Public Library of Science In Vivo Imaging of Hierarchical Spatiotemporal Activation of Caspase-8 during Apoptosis. 2433/74881 Yagi, Toshiharu 1980/01/23 Kyoto University 三フッ化エチレンの単独重合体および共重合体の構造と物性 STRUCTURE AND PROPERTIES OF HOMOPOLYMER AND COPOLYMERS OF TRIFLUOROETHYLENE 2433/172347 Kawakami, Tetsuo 2013/02/27 Behavior of zircon at the schist/migmatite transition is investigated. Syn-metamorphic overgrowth is rare in zircon in schists, whereas zircon in migmatites has rims with low Th/U that give 90.3 ± 2.2 Ma U–Pb concordia age. Between inherited core and the metamorphic rim, a thin, dark-CL annulus containing melt inclusion is commonly developed, suggesting that it formed contemporaneous with the rim in the presence of melt. In diatexites, the annulus is further truncated by the brighter-CL overgrowth, suggesting the resorption and regrowth of the zircon after near-peak metamorphism. Part of the zircon rim crystallized during the solidification of the melt in migmatites. Preservation of angular-shaped inherited core of 5–10 μm in zircon included in garnet suggests that zircon of this size did not experience resorption but developed overgrowths during near-peak metamorphism. The Ostwald ripening process consuming zircon less than 5–10 μm is required to form new overgrowths. Curved crystal size distribution pattern for fine-grained zircons in a diatexite sample may indicate the contribution of this process. Zircon less than 20 μm is confirmed to be an important sink of Zr in metatexites, and ca. 35-μm zircon without detrital core are common in diatexites, supporting new nucleation of zircon in migmatites. In the Ryoke metamorphic belt at the Aoyama area, monazite from migmatites records the prograde growth age of 96.5 ± 1.9 Ma. Using the difference of growth timing of monazite and zircon, the duration of metamorphism higher than the amphibolite facies grade is estimated to be ca. 6 Myr. 591 0010-7999 3 Contributions to Mineralogy and Petrology 575 165 Springer-Verlag Zircon Behavior of zircon in the upper-amphibolite to granulite facies schist/migmatite transition, Ryoke metamorphic belt, SW Japan: constraints from the melt inclusions in zircon 2433/157959 Masunaga, S 2011/11/29 [Objectives]The aim was to evaluate the influence of bevacizumab on intratumour oxygenation status and lung metastasis following radiotherapy, with specific reference to the response of quiescent (Q) cell populations within irradiated tumours. [Methods]B16-BL6 melanoma tumour-bearing C57BL/6 mice were continuously given 5-bromo-2-deoxyuridine (BrdU) to label all proliferating (P) cells. They received γ-ray irradiation following treatment with the acute hypoxia-releasing agent nicotinamide or local mild temperature hyperthermia (MTH) with or without the administration of bevacizumab under aerobic conditions or totally hypoxic conditions, achieved by clamping the proximal end of the tumours. Immediately after the irradiation, cells from some tumours were isolated and incubated with a cytokinesis blocker. The responses of the Q and total (P + Q) cell populations were assessed based on the frequency of micronuclei using immunofluorescence staining for BrdU. In the other tumour-bearing mice, macroscopic lung metastases were enumerated 17 days after irradiation. [Results]3 days after bevacizumab administration, acute hypoxia-rich total cell population in the tumour showed a remarkably enhanced radiosensitivity to γ-rays, and the hypoxic fraction (HF) was reduced, even after MTH treatment. However, the hypoxic fraction was not reduced after nicotinamide treatment. With or without γ-ray irradiation, bevacizumab administration showed some potential to reduce the number of lung metastases as well as nicotinamide treatment. [Conclusion]Bevacizumab has the potential to reduce perfusion-limited acute hypoxia and some potential to cause a decrease in the number of lung metastases as well as nicotinamide. 1138 0007-1285 The British journal of radiology 1131 84 British Institute of Radiology acute hypoxia Reducing intratumour acute hypoxia through bevacizumab treatment, referring to the response of quiescent tumour cells and metastatic potential. 2433/131824 Onoguchi, Kazuhide 2010/06/29 In virus-infected cells, RIG-I-like receptor (RLR) recognizes cytoplasmic viral RNA and triggers innate immune responses including production of type I and III interferon (IFN) and the subsequent expression of IFN-inducible genes. Interferon-beta promoter stimulator 1 (IPS-1, also known as MAVS, VISA and Cardif) is a downstream molecule of RLR and is expressed on the outer membrane of mitochondria. While it is known that the location of IPS-1 is essential to its function, its underlying mechanism is unknown. Our aim in this study was to delineate the function of mitochondria so as to identify more precisely its role in innate immunity. In doing so we discovered that viral infection as well as transfection with 5'ppp-RNA resulted in the redistribution of IPS-1 to form speckle-like aggregates in cells. We further found that Mitofusin 1 (MFN1), a key regulator of mitochondrial fusion and a protein associated with IPS-1 on the outer membrane of mitochondria, positively regulates RLR-mediated innate antiviral responses. Conversely, specific knockdown of MFN1 abrogates both the virus-induced redistribution of IPS-1 and IFN production. Our study suggests that mitochondria participate in the segregation of IPS-1 through their fusion processes. 1553-7374 7 PLoS pathogens 6 Public Library of Science Virus-infection or 5'ppp-RNA activates antiviral signal through redistribution of IPS-1 mediated by MFN1. 2433/118438 岡田, 弘 1985/02/27 triple-stain techniqueを用いヒト精子acrosome reactionを観察した.1) mBWW中では培養6時間後まではacrosome reaction陽性精子の割合は漸増した.2) human serum albuminを含まない培養液中ではacrosome reactionはおこらなかった.Caイオン,Ca ionophore A23187, trypsinにはacrosome reactionの誘発作用を認めた.3)不妊患者精子の中で乏精子症患者の精子や運動率が20%以下の精子はFertile Maleの精子に比しacrosome reactionをおこさせると困難であった.これが不妊症の一因となっている可能性を示した 440 0018-1994 3 泌尿器科紀要 429 31 泌尿器科紀要刊行会 Male infertility Studies on male infertility--acrosome reaction of the human sperm incubated in vitro 男性不妊に関する研究 --in vitroにおけるヒト精子acrosome reaction-- 2433/139442 Watari-Goshima, Natsuko 2011/01/19 In vertebrates, the proximal and distal sensory ganglia of the branchial nerves are derived from neural crest cells (NCCs) and placodes, respectively. We previously reported that in Hoxa3 knockout mouse embryos, NCCs and placode-derived cells of the glossopharyngeal nerve were defective in their migration. In this report, to determine the cell-type origin for this Hoxa3 knockout phenotype, we blocked the expression of the gene with antisense morpholino oligonucleotides (MO) specifically in either NCCs/neural tube or placodal cells of chicken embryos. Our results showed that HOXA3 function was required for the migration of the epibranchial placode-derived cells and that HOXA3 regulated this cell migration in both NCCs/neural tube and placodal cells. We also report that the expression pattern of chicken HOXA3 was slightly different from that of mouse Hoxa3. 101 1449-2288 7 International Journal of Medical Sciences 87 Ivyspring International Publisher Hoxa3 Chicken HOXA3 Gene: Its Expression Pattern and Role in Branchial Nerve Precursor Cell Migration 2433/147969 Nagao, Rina 2011/12/15 We investigated the effect of a novel Wnt/β-catenin signaling inhibitor, AV65 on imatinib mesylate (IM)-sensitive and -resistant human chronic myeloid leukemia (CML) cells in vitro. AV65 inhibited the proliferation of various CML cell lines including T315I mutation-harboring cells. AV65 reduced the expression of β-catenin in CML cells, resulting in the induction of apoptosis. Moreover, AV65 inhibited the proliferation of hypoxia-adapted primitive CML cells that overexpress β-catenin. The combination of AV65 with IM had a synergistic inhibitory effect on the proliferation of CML cells. These findings suggest that AV65 could be a novel therapeutic agent for the treatment of CML. 100 0304-3835 1 Cancer letters 91 312 Elsevier Ireland Ltd. β-Catenin Growth inhibition of imatinib-resistant CML cells with the T315I mutation and hypoxia-adaptation by AV65 - a novel Wnt/β-catenin signaling inhibitor. 2433/152375 Yoshikawa, Yuko 2011/12/14 We studied the changes in the higher-order structure of a megabase-size DNA (S120-1 DNA) under different spermidine (SPD) concentrations through single-molecule observations using fluorescence microscopy (FM) and atomic force microscopy (AFM). We examined the difference between the folding transitions in S120-1 DNA and sub-megabase-size DNA, T4 DNA (166 kbp). From FM observations, it is found that S120-1 DNA exhibits intra-chain segregation as the intermediate state of transition, in contrast to the all-or-none nature of the transition on T4 DNA. Large S120-1 DNA exhibits a folding transition at lower concentrations of SPD than T4 DNA. AFM observations showed that DNA segments become aligned in parallel on a two-dimensional surface as the SPD concentration increases and that highly intense parallel alignment is achieved just before the compaction. S120-1 DNA requires one-tenth the SPD concentration as that required by T4 DNA to achieve the same degree of parallel ordering. We theoretically discuss the cause of the parallel ordering near the transition into a fully compact state on a two-dimensional surface, and argue that such parallel ordering disappears in bulk solution. 1089-7690 22 The Journal of chemical physics 135 American Institute of Physics atomic force microscopy Critical behavior of megabase-size DNA toward the transition into a compact state. 2433/153283 Hamaguchi, Kiyomi 2012/02/28 This study explored the physiological roles of PGE-type receptor 4 (EP4) in auditory function. EP4-deficient mice exhibited slight hearing loss and a reduction of distortion-product otoacoustic emissions (DPOAEs) with loss of outer hair cells (OHCs) in cochleae. After exposure to intense noise, these mice showed significantly larger threshold shifts of auditory brain-stem responses (ABRs) and greater reductions of DPOAEs than wild-type mice. A significant increase of OHC loss was confirmed morphologically in the cochleae of EP4-deficient mice. Pharmacological inhibition of EP4 had a similar effect to genetic deletion, causing loss of both hearing and OHCs in C57BL/6 mice, indicating a critical role for EP4 signaling in the maintenance of auditory function. Pharmacological activation of EP4 significantly protected OHCs against noise trauma, and attenuated noise-induced hearing loss in C57BL/6 mice. These findings suggest that EP4 signaling is necessary for the maintenance of cochlear physiological function and for cochlear protection against noise-induced damage, in particular OHCs. EP4 might therefore be an effective target for cochlear disease therapeutics. 1847 0028-3908 4 Neuropharmacology 1841 62 Elsevier Ltd.

In this study, the substrate-induced modulation of synchronized beating in cultured cardiomyocyte tissue was systematically characterized on elasticity-tunable substrates to elucidate the effect of biomechanical coupling. We found that myocardial conduction is significantly promoted when the rigidity of the cell culture environment matches that of the cardiac cells (4 kiloPascals). The stability of spontaneous target wave activity and calcium transient alternans in high frequency-paced tissue were both enhanced when the cell substrate and cell tissue showed the same rigidity. By adapting a simple theoretical model, we reproduced the experimental trend on the rigidity matching for the synchronized excitation. We conclude that rigidity matching in cell-to-substrate interactions critically improves cardiomyocyte-tissue synchronization, suggesting that mechanical coupling plays an essential role in the dynamic activity of the beating heart. 387 0006-3495 3 Biophysical Journal 379 102 Elsevier Inc. Rigidity Matching between Cells and the Extracellular Matrix Leads to the Stabilization of Cardiac Conduction 2433/88957 Yazawa, Shigenobu 2009/12/11 Despite long-standing interest, the molecular mechanisms underlying the establishment of anterior–posterior (AP) polarity remain among the unsolved mysteries in metazoans. In the planarians (a family of flatworms), canonical Wnt/β-catenin signaling is required for posterior specification, as it is in many animals. However, the molecular mechanisms regulating the posterior-specific induction of Wnt genes according to the AP polarity have remained unclear. Here, we demonstrate that Hedgehog (Hh) signaling is responsible for the establishment of AP polarity via its regulation of the transcription of Wnt family genes during planarian regeneration. We found that RNAi gene knockdown of Dugesia japonica patched (Djptc) caused ectopic tail formation in the anterior blastema of body fragments, resulting in bipolar-tails regeneration. In contrast, RNAi of hedgehog (Djhh) and gli (Djgli) caused bipolar-heads regeneration. We show that Patched-mediated Hh signaling was crucial for posterior specification, which is established by regulating the transcription of Wnt genes via downstream Gli activity. Moreover, differentiated cells were responsible for the posterior specification of undifferentiated stem cells through Wnt/β-catenin signaling. Surprisingly, Djhh was expressed in neural cells all along the ventral nerve cords (along the AP axis), but not in the posterior blastema of body fragments, where the expression of Wnt genes was induced for posteriorization. We therefore propose that Hh signals direct head or tail regeneration according to the AP polarity, which is established by Hh signaling activity along the body's preexisting nervous system. 100年来の謎に迫る－体の極性を決める仕組みを解明しました. 京都大学プレスリリース. 2009-12-08. http://www.kyoto-u.ac.jp/ja/news_data/h/h1/news6/2009/091208_2.htm 0027-8424 Proceedings of the National Academy of Sciences.

They are characterized by combining x-ray diffraction, Al-K edge x-ray absorption near edge structures (XANESs), high resolution transmission electron microscope (TEM) imaging, TEM analysis, and a series of first principles calculations. The films are composed of textured wurtzite grains with c planes parallel to the substrate. The distance between c planes expands significantly when the Al concentration is greater than 10 at. %. The expansion disappears after annealing the films at above 800 °C. High density of dislocationlike defects is found in the as deposited film. Any segregation of Al cannot be detected either at the grain boundaries or inside the grains. The lattice expansion toward c axis and the experimental XANES can be satisfactorily explained by taking a hypothetical homologous model with the composition of (ZnO)3(Al2O3) as the local environment of Al in the supersaturated solid solution. Simplified substitutional models with Al at the Zn site in wurtzite ZnO cannot explain these experimental results. First principles calculations show that the homologous phase is energetically more favorable than the simplified substitutional models, although decomposition into ZnO and ZnAl2O4 is more favorable than the homologous phase. The local atomic structures of the supersaturated solid solution are therefore concluded to be analogous to the metastable homologous phase. 0021-8979 1 JOURNAL OF APPLIED PHYSICS http://link.aip.org/link/?JAPIAU/103/014309/1 103 American Institute of Physics Atomic structures of supersaturated ZnO-AL(2)O(3) solid solutions 2433/80150 Suzuki, Keita W. 2009/07/30 The estuarine turbidity maximum (ETM) that develops in the lower salinity areas of macrotidal estuaries has been considered as an important nursery for many fish species. Mysids are one of the dominant organisms in the ETM, serving as a key food source for juvenile fish. To investigate the horizontal distribution and population dynamics of dominant mysids in relation to the fluctuation of physical conditions (temperature, salinity, turbidity, and freshwater discharge), we conducted monthly sampling (hauls of a ring net in the surface water) along the macrotidal Chikugo River estuary in Japan from May 2005 to December 2006. Hyperacanthomysis longirostris was the dominant mysid in the estuary, usually showing peaks of density and biomass in or close to the ETM (salinity 1-10). In addition, intra-specific differences (life-cycle stage, sex, and size) in horizontal distribution were found along the estuary. Larger males and females, particularly gravid females, were distributed upstream from the center of distribution where juveniles were overwhelmingly dominant. Juveniles increased in size toward the sea in marked contrast with males and females. The findings suggest a possible system of population maintenance within the estuary; gravid females release juveniles in the upper estuary, juveniles grow during downstream transport, young males and females mature during the upstream migration. Density and biomass were primarily controlled by seasonal changes of temperature, being high at intermediate temperatures (ca. 15-25 ｡・ in late spring and fall) and being low at the extreme temperatures (ca. 10 ｡・ in midwinter and 30 ｡・ in midsummer). High density (up to 666 ind. m-3) and biomass (up to 168 mg dry weight m-3) of H. longirostris were considered to be comparable with those of copepods in the estuary. 528 02727714 4 Estuarine, Coastal and Shelf Science 516 83 Elsevier Ariake Sea Horizontal distribution and population dynamics of the dominant mysid Hyperacanthomysis longirostris along a temperate macrotidal estuary (Chikugo River estuary, Japan) 2433/76849 Kokubo, Tadashi 1980/01/31 375 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 355 57 Institute for Chemical Research, Kyoto University Preparation of Li₂O･2SiO₂ Ceramics with Oriented Microstructures by Unidirectional Solidification of Their Melts 2433/77052 Sakka, Sumio 1983/12/01 396 0023-6071 5-6 Bulletin of the Institute for Chemical Research, Kyoto University 376 61 Institute for Chemical Research, Kyoto University Low Temperature Preparation of Oxide Glasses and Ceramics from Metal Alkoxide Solutions 2433/51499 林, 昭三 1987/11/30 218 0285-7049 木材研究・資料 211 23 京都大学木材研究所 Catalogue of Microscope Slides in the Xylarium, Wood Research Institute, Kyoto University No. 1 ～ No. 6,000 <資料>材鑑調査室所蔵顕微鏡用プレパラート目録 : No.1～No.6,000 2433/145971 Ukai, Yuuta 2011/07/30 Gpx2, one of three glutathione peroxidase homologs (Gpx1, Gpx2, and Gpx3) in Saccharomyces cerevisiae, is an atypical 2-Cys peroxiredoxin that prefers to use thioredoxin as a reducing agent in vitro. Despite Gpx2 being an antioxidant, no obvious phenotype of gpx2Δ mutant cells in terms of oxidative stress has yet been found. To gain a clue as to Gpx2’s physiological function in vivo, here we identify its intracellular distribution. Gpx2 was found to exist in the cytoplasm and mitochondria. In mitochondria, Gpx2 was associated with the outer membrane of the cytoplasmic-side, as well as the inner membrane of the matrix-side. The redox state of the mitochondrial Gpx2 was regulated by Trx1 and Trx2 (cytoplasmic thioredoxin), and by Trx3 (mitochondrial matrix thioredoxin). In addition, we found that the disruption of GPX2 reduced the sporulation efficiency of diploid cells. 585 0006-291X 3 Biochemical and Biophysical Research Communications 580 411 Elsevier Inc.

Although there are several reports on the chemopreventive abilities of dietary flavonoids in chemically induced colon carcinogenesis, those have not been addressed in an obesity-associated carcinogenesis model. In the present study, the effects of 3 flavonoids (chrysin, quercetin and nobiletin) on modulation of the occurrence of putative preneoplastic lesions, aberrant crypt foci (ACF), and β-catenin-accumulated crypts (BCACs) in the development of colon cancer were determined in male db/db mice with obesity and diabetic phenotypes. Male db/db mice were given 3 weekly intraperitoneal injections of azoxymethane (AOM) to induce the ACF and BCAC. Each flavonoid (100 ppm), given in the diet throughout the experimental period, significantly reduced the numbers of ACF by 68–91% and BCAC by 64–71%, as well as proliferation activity in the lesions. Clinical chemistry results revealed that the serum levels of leptin and insulin in mice treated with AOM were greater than those in the untreated group. Interestingly, the most pronounced suppression of development of preneoplastic lesions and their proliferation were observed in the quercetin-fed group, in which the serum leptin level was lowered. Furthermore, quercetin-feeding decreased leptin mRNA expression and secretion in differentiated 3T3-L1 mouse adipocytes. These results suggest that the present dietary flavonoids are able to suppress the early phase of colon carcinogenesis in obese mice, partly through inhibition of proliferation activity caused by serum growth factors. Furthermore, they indicate that certain flavonoids may be useful for prevention of colon carcinogenesis in obese humans. 283 00092797 2 Chemico-Biological Interactions 276 183 Elsevier ACF Dietary flavonoids suppress azoxymethane-induced colonic preneoplastic lesions in male C57BL/KsJ-db/db mice 2433/95085 Yokokawa, Ryuji 2010/01/07 Bio-concentrators have been proposed to concentrate and detect tiny amount of cells, DNAs, or proteins in a microfluidic system. Concentrating processes have been experimentally studied and discussed as a result of concentration caused by multiple electrokinetic phenomena. Here, we have investigated individual electrokinetic phenomenon in a DNA concentrator to propose a design guide for a micro-bio-concentrator. Three dominant electrokinetic phenomena: dielectrophoresis (DEP), electrophoresis (EP), and AC electroosmotic flow (AC-EOF) are experimentally and theoretically evaluated. DNA mobility due to DEP was separately studied by utilizing quadrupole electrodes generating a uniform field gradient, which enables us to derive a DEP force on the order of 10-13 N acting on a single DNA molecule. Using the theoretical model the DEP force on the order of 10-12 N, close to the experimental result, was calculated. The EP force estimated from the average charge per base pair of DNA molecule was on the order of 10-9 N. Compared with these two forces, AC-EOF generating a flow velocity of 100-200 μm/s, globally dominates the manipulation of DNA molecules throughout the concentrator. However, the three-dimensional observation of molecule distribution reveals that the EP force has a significant role in holding the DNA molecules at the electrode centre. The results not only support the proposal that the biomolecular concentrator should be designed to utilize AC-EOF and EP [1,2], but also provide approximate estimates for the DEP and EP forces, and the AC-EOF velocity which will allow us to design a concentrator with a given experimental condition. 775 09254005 2 Sensors and Actuators B: Chemical 769 143 Elsevier DNA concentrator Individual evaluation of DEP, EP and AC-EOF effects on λDNA molecules in a DNA concentrator 2433/108577 Kurihara, Takeo 2006/10/30 In many benthic organisms with a planktonic larval stage, local populations have different morphology. Such difference may arise from some of the following proximate mechanisms. “Local recruitment (LR)”: no larvae move between local populations, and segregated populations possess alleles coding for locally adaptive morphology. “Intragenerational selection (IS)”: larvae move between local populations, and individuals with alleles for locally adaptive morphology survive after recruitment. “Phenotypic plasticity (PP)”: larvae move between local populations and show phenotypic plasticity to adapt to a locality after recruitment. We examined which mechanism explains our finding that a planktonic developer Turbo coronatus coronatus (Gastropoda) had significantly longer spines on its shell on more exposed shores at scales of < 2 km. Experiments at Ishigaki Island, Okinawa, Japan, showed the following results. (a) Shorter- and longer-spined populations occurring within 2 km showed non-significant ϕ low st values (−0.0040 to 0.00095) for the mitochondrial DNA COI region. This suggests no segregation of the local populations, supporting the mechanisms IS and PP. (b) T. c. coronatus generated significantly longer spines 70 days after being transplanted to the habitat of a longer-spined population, supporting IS and PP. (c) Individuals caged in the sea for 79 days generated longer spines than individuals in the laboratory, supporting PP. In conclusion, shore-specific morphology of T. c. coronatus arises most likely from phenotypic plasticity and possibly from intragenerational selection. 1008 0289-0003 11 Zoological Science 999 23 Zoological Society of Japan Proximate Mechanisms Causing Morphological Variation in a Turban Snail Among Different Shores 2433/109903 Kawakita, H. 2009/08/30 It has been known that giant DNA shows structural transitions in aqueous solutions under the existence of counterions and other polymers. However, the mechanism of these transitions has not been fully understood. In this study, we directly observed structures of probed (dye-labeled), dilute DNA chains in unprobed DNA/polyethylene glycol (PEG)/monovalent salt (NaCl) aqueous solutions with fluorescent microscopy to examine this mechanism. Specifically, we varied the PEG molecular weight and salt concentration to investigate the effect of competition between the depletion and electrostatic interactions on the coil-globule transition and the aggregate formation. It was found that the globules coexist with the aggregates when the unprobed DNA chains have a concentration higher than their overlap concentration. We discuss the stability of the observed structures on the basis of a free energy model incorporating the attractive depletion energy, the repulsive electrostatic energy, and the chain bending energy. This model suggested that both of the globules and aggregates are more stable than the random coil at high salt concentrations/under existence of PEG and the transition occurs when the depletion interaction overwhelms the electrostatic interaction. However, the coexistence of the globule and aggregate was not deduced from the thermodynamic model, suggesting a nonequilibrium aspect of the DNA solution and metastabilities of these structures. Thus, the population ratio of globules and aggregates was also analyzed on the basis of a kinetic model. The analysis suggested that the depletion interaction dominates this ratio, rationalizing the coexistence of globules and aggregates. 0021-9606 9 JOURNAL OF CHEMICAL PHYSICS http://link.aip.org/link/JCPSA6/v131/i9/p094901/s1 131 American Institute of Physics aggregates (materials) Formation of globules and aggregates of DNA chains in DNA/polyethylene glycol/monovalent salt aqueous solutions 2433/112039 矢吹, 芳一 1960/10/30 Since Lipschiltz and others have presumed t he virus as a suspicious cause of the condyloma acuminatum, the virus infection theory has been considered as the most probable etiology of the condyloma acuminatum. The author, recently, has studied its fine structure by means of electron-microscope in twenty-five cases. The results are summarized as follows. 1) In only tw o out of the twenty-five cases, the abnormal granules are seen in the cytoplasm of the prickle cell, and are suspicious enough as a virus of 150-250mp in size. 2) In the six cases including the above mentioned two, some changes are noticed in the cytoplasm ; i. e. a relatively non-structural clear change in, the two cases and a vacuole like change in the rest of the four. 3) In all the twenty-five cases, th e stratum corneum is generally edematous and less cornified. 4 ) In the nineteen cases excluding above mentioned six, the prickle cell stroma reveals generally clear structure. 5) The nucleus an d nucleoles of the prickle cell are generally larger and relatively stable. 6) The mitochondria reveals remarkable enlarging deformity and the arrangement of the cristae mitochondriales is rarely in order. 7) The endoplasmic reticulum, Golgi a rea, etc. are relatively less developed. 8) The tonofibril has remarkably decreased in the cells of which c y toplasm revealed the above mentioned degenerations. 1087 0018-1994 11 泌尿器科紀要 1073 6 泌尿器科紀要刊行会 Electron-Microscopic Studies on the Condyloma Acuminatum by Ultra-thin Sectioning 超薄切片法に依るCondyloma Acuminatumの電子顕微鏡的観察 2433/126658 Kobayashi, Junya 2010/05/30 Werner syndrome (WS), caused by mutation of the WRN gene, is an autosomal recessive disorder associated with premature aging and predisposition to cancer. WRN belongs to the RecQ DNA helicase family, members of which play a role in maintaining genomic stability. Here, we demonstrate that WRN rapidly forms discrete nuclear foci in an NBS1-dependent manner following DNA damage. NBS1 physically interacts with WRN through its FHA domain, which interaction is important for the phosphorylation of WRN. WRN subsequently forms DNA damage-dependent foci during the S phase, but not in the G1 phase. WS cells exhibit an increase in spontaneous focus formation of poleta and Rad18, which are important for translesion synthesis (TLS). WRN also interacts with PCNA in the absence of DNA damage, but DNA damage induces the dissociation of PCNA from WRN, leading to the ubiquitination of PCNA, which is essential for TLS. This dissociation correlates with ATM/NBS1-dependent degradation of WRN. Moreover, WS cells show constitutive ubiquitination of PCNA and interaction between PCNA and Rad18 E3 ligase in the absence of DNA damage. Taken together, these results indicate that WRN participates in the TLS pathway to prevent genomic instability in an ATM/NBS1-dependent manner. 444 0047-6374 6 Mechanisms of ageing and development 436 131 Elsevier Ireland Ltd.

However, due to technological difficulties, the intraperoxisomal redox state remain elusive and the effect of peroxisome-deficiency on the intracellular redox state is controversial. A newly developed, genetically-encoded fluorescence resonance energy transfer (FRET) probe, Redoxfluor, senses the physiological redox state via its internal disulfide bonds, resulting in a change in conformation of the protein leading to a FRET response. We made use of Redoxfluor to measure the redox states at the subcellular level in yeast and Chinese hamster ovary (CHO) cells. In wild-type peroxisomes harboring an intact fatty acid beta-oxidation system, the redox state within the peroxisomes was more reductive than that in the cytosol, despite the fact that reactive oxygen species were generated within the peroxisomes. Interestingly, we observed that the redox state of the cytosol of cell mutants for peroxisome-assembly, regarded as models for a neurological metabolic disorder, was more reductive than that of the wild-type cells in yeast and CHO cells. Furthermore, Redoxfluor was utilized to develop an efficient system for screening of drugs that moderate the abnormal cytosolic redox state in the mutant CHO cell lines for peroxisome assembly, without affecting the redox state of normal cells. 神経疾患モデル細胞と正常細胞の酸化還元状態の違いを検知できるセンサータンパク質の開発に成功. 京都大学プレスリリース. 2010-05-25. http://www.kyoto-u.ac.jp/ja/news_data/h/h1/news6/2010/100525_1.htm 3766 1098-5549 15 Molecular and cellular biology 3758 30 American Society for Microbiology A Novel Fluorescent Sensor Protein for Visualization of Redox States in the Cytoplasm and in Peroxisomes. 2433/159047 Izumi, Yasuhiko 2012/06/27 The nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response element (ARE) pathway is a cellular defense system against oxidative stress. Activation of this pathway increases expression of antioxidant enzymes. Epidemiological studies have demonstrated that the consumption of fruits and vegetables is associated with reduced risk of contracting a variety of human diseases. The aim of this study is to find Nrf2-ARE activators in dietary fruits and vegetables. We first attempted to compare the potency of ARE activation in six fruit and six vegetables extracts. Green perilla (Perilla frutescens var. crispa f. viridis) extract exhibited high ARE activity. We isolated the active fraction from green perilla extract through bioactivity-guided fractionation. Based on nuclear magnetic resonance and mass spectrometric analysis, the active ingredient responsible for the ARE activity was identified as 2',3'-dihydroxy-4',6'-dimethoxychalcone (DDC). DDC induced the expression of antioxidant enzymes, such as γ-glutamylcysteine synthetase (γ-GCS), NAD(P)H: quinone oxidoreductase-1 (NQO1), and heme oxygenase-1. DDC inhibited the formation of intracellular reactive oxygen species and the cytotoxicity induced by 6-hydroxydopamine. Inhibition of the p38 mitogen-activated protein kinase pathway abolished ARE activation, the induction of γ-GCS and NQO1, and the cytoprotective effect brought about by DDC. Thus, this study demonstrated that DDC contained in green perilla enhanced cellular resistance to oxidative damage through activation of the Nrf2-ARE pathway. 青ジソから老化やメタボリックシンドローム予防に有望な生体内抗酸化力を高める成分を発見. 京都大学プレスリリース. 2012-08-06. 679 0891-5849 4 Free radical biology & medicine 669 53 Elsevier Inc.

Gelatin was dehydrothermally crosslinked at 140° C for 48 h in a water in oil emulsion state. When cultured with the gelatin hydrogel microspheres in round, U-bottomed wells of 96-well plates coated with poly(vinyl alcohol) MSC formed aggregates homogeneously incorporating the microspheres. The viability of the cell aggregates was significantly higher compared with that of aggregates formed without microspheres. MSC proliferation in the aggregates depended on the number and diameter of the incorporated microspheres. Higher MSC proliferation was observed for aggregates incorporating a greater number of larger gelatin microspheres. When evaluated as a measure of aerobic glycolysis the ratio of l-lactic acid production/glucose consumption in MSC was significantly lower for MSC cultured with gelatin microspheres than those without microspheres. MSC production of alkaline phosphatase (ALP) and sulfated glycosaminaglycan (sGAG) was examined to evaluate their potential osteogenic and chondrogenic differentiation. The amount of ALP produced was significantly higher for MSC aggregates cultured with gelatin microspheres than that of MSC cultured without microspheres. On the other hand, the amount of sGAG produced was significantly lower for MSC aggregates containing microspheres. It is concluded that the incorporation of gelatin hydrogel microspheres prevents the aggregated MSC suffering from a lack of oxygen, resulting in enhanced MSC aggregation and cell proliferation and osteogenic differentiation. 2803 1742-7061 7 Acta biomaterialia 2797 7 Elsevier Ltd.

For clinical use, it is important to develop a way to isolate BMSCs from bone marrow in a closed system without centrifugation. After screening 200 biomaterials, we developed a device containing a nonwoven fabric filter composed of rayon and polyethylene. The filter selectively traps BMSCs among mononuclear cells in bone marrow based on affinity, not cell size. The cells are then recovered by the retrograde flow. Using canine and human bone marrow cells, the biological properties of BMSCs isolated by the device were compared with those obtained by conventional methods using centrifugation. The total number isolated by the device was larger, as was the number of CD106(+)/STRO-1(+) double-positive cells. The cells showed osteogenic, chondrogenic, and adipogenic differentiation potential in vitro. Finally, the direct transplantation of cells isolated by the device without in vitro cultivation accelerated bone regeneration in a canine model of osteonecrosis in vivo. The proposed method is rapid and efficient, does not require a biological clean area, and will be useful for the clinical application of mesenchymal stem cells in bone marrow. 91 1937-3392 1 Tissue engineering.

However, the mechanism of pathogen detection is still unclear. For the successful application of biopesticides to termites in nature, it would be beneficial to identify substances that could disrupt the termite's ability to perceive pathogens. We hypothesized that termites can perceive pathogens and this ability plays an important role in effective hygiene behavior. In this study, pathogen-detection in the subterranean termite Coptotermes formosanus was investigated. We performed quantitative assays on conidia removal by grooming behavior using epifluoresence microscopy and Y-maze tests to examine the perception of fungal odor by termites. Three species each of high- and low-virulence entomopathogenic fungi were used in each test. The results demonstrated that termites removed conidia more effectively from a nestmate's cuticle if its odor elicited stronger aversion. Highly virulent pathogens showed higher attachment rates to termite surfaces and their odors were more strongly avoided than those of low-virulence isolates in the same species. Moreover, termites appeared to groom each other more persistently when they had more conidia on their bodies. In brief, insect perception of pathogen-related odor seems to play a role in the mechanism of their hygiene behavior. 1932-6203 10 PloS one 7 Public Library of Science Odor Aversion and Pathogen-Removal Efficiency in Grooming Behavior of the Termite Coptotermes formosanus. 2433/168168 山本, 一淸 1941/04/01 153 239 天界 = The heavens 144 21 東亞天文協會 天文用語の手引き(1) 2433/168521 Jo, Jun-Ichiro 2012/11/29 The objective of this study was to design and prepare a new contrast agent of magnetic resonance (MR) imaging for the evaluation of therapeutic angiogenesis. Diethylenetriaminepentaacetic acid (DTPA) residue of a chelator was chemically introduced to dextran with a molecular weight of 74,000 (dextran-DTPA). Cyclic peptide containing an arginine-glycine-aspartic acid (RGD) sequence (cyclic RGD) with an inherent affinity for the α(v)β(3) integrin was then introduced to dextran-DTPA (Cyclic RGD-dextran-DTPA). Gd(3+) was added to cyclic RGD-dextran-DTPA to prepare a dextran-based MR contrast agent (Cyclic RGD-dextran-DTPA-Gd). Cyclic RGD-dextran-DTPA-Gd had affinity for cells expressing the α(v)β(3) integrin and showed a higher longitudinal relaxivity compared with DTPA-Gd of an MR contrast agent clinically used. Right femoral, external iliac, and deep femoral and circumflex arteries and veins were surgically ligated to prepare a mouse model of hindlimb ischemia. A laser Doppler analysis and histological evaluation confirmed that hindlimb ischemia healed naturally and was accompanied by angiogenesis, while α(v)β(3) integrin was expressed in the ischemic-angiogenic region without any treatment. Mice at 7 days after vascular ligation were used as an angiogenesis model. When intravenously injected into mice with hindlimb ischemia, cyclic RGD-dextran-DTPA accumulated in the ischemic-angiogenic region and showed the MR ability to detect the ischemic-angiogenic region. It is concluded that cyclic RGD-dextran-DTPA-Gd is a promising material for evaluation of therapeutic angiogenesis. 39 1937-3341 1-2 Tissue engineering. Part A 30 19 Mary Ann Liebert, Inc.

Although it was long assumed that the ER dynamics is actomyosin-driven, the responsible myosins were not identified, and the ER streaming was not characterized quantitatively. Here we developed software to generate a detailed velocity-distribution map for the GFP-labeled ER. This map revealed that the ER in the most peripheral plane was relatively static, whereas the ER in the inner plane was rapidly streaming with the velocities of up to approximately 3.5 microm/sec. Similar patterns were observed when the cytosolic GFP was used to evaluate the cytoplasmic streaming. Using gene knockouts, we demonstrate that the ER dynamics is driven primarily by the ER-associated myosin XI-K, a member of a plant-specific myosin class XI. Furthermore, we show that the myosin XI deficiency affects organization of the ER network and orientation of the actin filament bundles. Collectively, our findings suggest a model whereby dynamic three-way interactions between ER, F-actin, and myosins determine the architecture and movement patterns of the ER strands, and cause cytosol hauling traditionally defined as cytoplasmic streaming. 6899 0027-8424 15 Proceedings of the National Academy of Sciences of the United States of America 6894 107 National Academy of Sciences Myosin-dependent endoplasmic reticulum motility and F-actin organization in plant cells 2433/172551 Murai, S. 2012/10/30 We study the hybridized plasmonic-photonic modes supported by two-dimensional arrays of metallic nanoparticles coupled to light-emitting optical waveguides. Localized surface plasmon polaritons in the metallic nanoparticles can couple to guided modes in the underlying waveguide, forming quasi-guided hybrid modes, or to diffracted orders in the plane of the array, forming surface lattice resonances. We consider three kinds of samples: one sustains quasi-guided modes only, another sustains surface lattice resonances only, and a third sample sustains both modes. This third sample constitutes the first demonstration of simultaneous coupling of localized surface plasmons to guided modes and diffracted orders. The dispersive properties of the modes in the samples are investigated through light extinction and emission spectroscopy. We elucidate the conditions that lead to the coexistence of surface lattice resonances and quasi-guided hybrid modes, and assess their potential for enhancing the luminescence of emitters embedded in the coupled waveguide. We find the largest increase in emission intensity for the surface lattice resonances, reaching up to a factor of 20. 4262 1094-4087 4 Optics Express 4250 21 Optical Society of America Hybrid plasmonic-photonic modes in diffractive arrays of nanoparticles coupled to light-emitting optical waveguides 2433/174251 Yanai, Goichi 2013/05/28 Islet transplantation is a minimally invasive treatment for severe diabetes. However, it often requires multiple donors to accomplish insulin-independence and the long-term results are not yet satisfying. Therefore, novel ways to overcome these problems have been explored. Isolated islets are fragile and susceptible to pro-apoptotic factors and poorly proliferative. In contrast, mesenchymal stem cells (MSCs) are highly proliferative, anti-apoptotic and pluripotent to differentiate toward various cell types, promote angiogenesis and modulate inflammation, thereby studied as an enhancer of islet function and engraftment. Electrofusion is an efficient method of cell fusion and nuclear reprogramming occurs in hybrid cells between different cell types. Therefore, we hypothesized that electrofusion between MSC and islet cells may yield robust islet cells for diabetes therapy. We establish a method of electrofusion between dispersed islet cells and MSCs in rats. The fusion cells maintained glucose-responsive insulin release for 20 days in vitro. Renal subcapsular transplantation of fusion cells prepared from suboptimal islet mass (1,000 islets) that did not correct hyperglycemia even if co-transplanted with MSCs, caused slow but consistent lowering of blood glucose with significant weight gain within the observation period in streptozotocin-induced diabetic rats. In the fusion cells between rat islet cells and mouse MSCs, RT-PCR showed new expression of both rat MSC-related genes and mouse β-cell-related genes, indicating bidirectional reprogramming of both β-cell and MSCs nuclei. Moreover, decreased caspase3 expression and new expression of Ki-67 in the islet cell nuclei suggested alleviated apoptosis and gain of proliferative capability, respectively. These results show that electrofusion between MSCs and islet cells yield special cells with β-cell function and robustness of MSCs and seems feasible for novel therapeutic strategy for diabetes mellitus. 膵島細胞と間葉系幹細胞の融合細胞を用いた糖尿病治療実験に成功 -新しい重症糖尿病治療法の開発に期待-. 京都大学プレスリリース. 2013-05-29. 1932-6203 5 PLoS ONE 8 Public Library of Science Electrofusion of Mesenchymal Stem Cells and Islet Cells for Diabetes Therapy: A Rat Model 2433/126634 Kamio, Naoka 2010/03/12 The efficacy and specificity of small interfering RNAs (siRNAs) are largely dependent on the siRNA sequence. Since only empirical strategies are currently available for predicting these parameters, simple and accurate methods for evaluating siRNAs are needed. To simplify such experiments, target genes are often tagged with reporters for easier readout. Here, we used a bicistronic vector expressing a target gene and green fluorescent protein (GFP) to create a system in which the effect of an siRNA sequence was reflected in the GFP expression level. Cells were transduced with the bicistronic vector, expression vectors for siRNA and red fluorescent protein (RFP). Flow cytometric analysis of the transduced cells revealed that siRNAs for the target gene silenced GFP from the bicistronic vector, but did not silence GFP transcribed without the target gene sequence. In addition, the mean fluorescence intensities of GFP on RFP-expressing cells correlated well with the target gene mRNA and protein levels. These results suggest that this flow cytometry-based method enables us to quantitatively evaluate the efficacy and specificity of siRNAs. Because of its simplicity and effectiveness, this method will facilitate the screening of effective siRNA target sequences, even in high-throughput applications. 503 0006-291X 3 Biochemical and biophysical research communications 498 393 Elsevier Bicistronic vector Use of bicistronic vectors in combination with flow cytometry to screen for effective small interfering RNA target sequences. 2433/123515 Sano, Hikaru 2009/02/27 Visible-light irradiation has been employed to promote a chemical reaction of 1-hexadecene with hydrogen-terminated silicon, yielding alkyl chains directly immobilized on bulk silicon surface. The resulting monolayer, that is, one type of self-assembled monolayer, was examined with water contact angle measurements, x-ray photoelectron spectroscopy, atomic force microscopy, and ellipsometry. While a part of the silicon surface was oxidized during the reaction, it was demonstrated that a compact monolayer was successfully formed both on p- and n-typed silicon substrates regardless of doping density. 862 1071-1023 2 Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures 858 27 American Vacuum Society Soft processing for formation of self-assembled monolayer on hydrogen-terminated silicon surface based on visible-light excitation 2433/115732 HIBI, Hatsuki 1996/04/29 SDラットに塩酸ブナゾシンを短期投与群として1ヵ月,長期投与群として3ヵ月,体重当たり1mg/kg強制経口投与した.精子濃度は塩酸ブナゾシン投与で著明に増加したが,運動性に差はみられなかった.精子の産生能もまた塩酸ブナゾシン投与で増加した.しかし,短期投与群と長期投与群とでは精子濃度,精子の産生能とも差は認められなかった.精巣上体尾部の精子濃度の増加した理由は,α遮断剤の投与で増加した精巣上体での精子の貯留スペース,及び短くなった精子の精巣上体通過時間,によると考えられた.又,α遮断剤は精巣への影響もあると考えられた 360 0018-1994 5 泌尿器科紀要 357 42 泌尿器科紀要刊行会 a-blocker ラット精巣上体管内液の精子濃度及び運動性, 精巣の精子産生能に対するα遮断剤の効果 Effect of alpha-blockers on epididymal sperm concentration, motility and testicular productivity in the rat 2433/131810 SUZUKI, Yoshikazu 2010/08/30 Porous ceramics based on refractory double oxides are promising for the next-generation diesel particulate filter (DPF) materials. Similarly to aluminum titanate (Al2TiO5), MgTi2O5 has a pseudobrookite-type crystal structure with low thermal expansion coefficients among oxides. Since MgTi2O5 has higher stability of pseudobrookite phase than Al2TiO5, it is expected that MgTi2O5-based materials are suitable for the next-generation DPF materials. In this study, porous MgTi2O5/MgTiO3 composites have been prepared by in situ processing (viz. reactive sintering) at 1000–1200°C. Porous MgTi2O5/MgTiO3 composites with very narrow pore-size distribution at the diameter of ∼1 µm were obtained by the pyrolytic reactive sintering at 1000–1100°C.

Confocal microscopy provides the information where the phase separation becomes distinct as the calcium concentration is increased. The charged domains tend to bud toward the interior of the vesicle. This budding is assumed to be due to an increase in the osmotic pressure, in cooperation with the spontaneous curvature change in the outer leaflet of the bilayer caused by the adsorption of calcium ions and charge screening effect. We interpret the effect of small cations on the phase separation based on the theoretical model with the Poisson–Boltzmann equation. 63 0009-2614 1-3 Chemical Physics Letters 59 496 Elsevier B.V.

GluD2 knockout mice show a reduced number of PF-PN synapses, suggesting that GluD2 is involved in synapse formation. Recent studies revealed that GluD2 induces presynaptic differentiation in a manner dependent on its N-terminal domain (NTD) through binding of Cbln1 secreted from cerebellar granule neurons. However, the underlying mechanism of the specific binding of the NTD to Cbln1 remains elusive. Here, we have identified the flap loop (Arg321-Trp339) in the NTD of GluD2 (GluD2-NTD) as a crucial region for the binding to Cbln1 and the induction of presynaptic differentiation. Both induction of presynaptic differentiation and binding of Cbln1 were abolished in the HEK cells expressing not wild-type GluD2 but GluD2 with mutations in the flap loop. Especially, single amino acid substitution of either Arg321 or Trp323 to alanine was sufficient to disable the GluD2 function. Finally, a homology model of GluD2-NTD suggested that the flap loop is located at the distal end, which appears consistent with an interaction with Cbln1 and a presynaptic varicosity. 541 0006-291X 3 Biochemical and biophysical research communications 537 398 Elsevier Inc.

The effect of joining temperature on the microstructure and tensile strength of the joint was investigated in this work. Metallographic analysis revealed that a good bonding was obtained at both the tungsten/nickel and nickel/steel interfaces, and the diffusion products were identified in the diffusion zone. Nano-indentation test across the joining interfaces demonstrated the effect of solid solution hardening in the diffusion zone. Tensile test showed that the maximum average tensile strength of not, vert, similar200 MPa was obtained for the joint diffusion bonded at 900 °C. The results were discussed in terms of the joining temperature and of the residual stress generated during joining process. 1810 0924-0136 13 Journal of Materials Processing Technology 1805 210 Elsevier B.V.

The thickness of the titania monolayer in the LbL films was 4–5 nm, which was consistent with the particle size of TALH in water. The conductivity and the electron mobility of the LbL films reached 10[−8]Scm[−1] and 10[−5] cm2 V[−1]s[−1], respectively. These results suggest that there exist percolation paths for the electron transport in the LbL film. Furthermore, it is demonstrated that photovoltaic properties of the LbL film can serve as an effective electron-transporting and accepting layer. 2498 0040-6090 8 Thin Solid Films 2493 519 Elsevier B.V.

Denuded-zone widths as small as 17 nm were observed below 1130 °C, indicating that a substantial population of “TEM invisible” voids of diameter <0.7 significantly contribute to interstitial annihilation. By using the obtained loop DZ width and the matrix sink strength (including the invisible voids), the activation energy of interstitial diffusion was determined to be 1.5 eV for the slower moving Si interstitial of SiC by application of simple reaction-diffusion equations. 1098-0121 7 Physical Review B 83 American Physical Society Analysis of grain boundary sinks and interstitial diffusion in neutron-irradiated SiC 2433/148420 Nitta, Noriko 2009/10/30 Void formation and structure change by heavy ion irradiation were investigated in GaSb and InSb thin films. The voids were formed after irradiation in both materials. The average diameter of the voids was about 15nm in GaSb and 20nm in InSb irradiated with 60 keV Snþ ions to a fluence of 0:25 x 1018 ions/m2 at room temperature. The void size in InSb is larger than that in GaSb. The large void size is quantitatively explained by the amount of induced vacancies obtained by the SRIM code simulation. The Debye-Scherrer rings were observed in the SAED patterns on both materials. The structure changes into a polycrystal by ion irradiation. Additionally, the 200 superlattice reflections in the [001] net pattern were almost absent, and the streak pattern along the h110i direction was observed in InSb. It is considered that the anti phase domains of different lengths are formed by ion irradiation. Ion irradiation transforms the structure of InSb from chemical ordering to chemical disordering via the formation of anti phase boundaries. 1063 1345-9678 6 MATERIALS TRANSACTIONS 1059 51 JAPAN INST METALS gallium antimonide Void Formation and Structure Change Induced by Heavy Ion Irradiation in GaSb and InSb 2433/148385 Nakajima, Kaoru 2009/10/30 Angular and energy distributions of fragment protons dissociated from HeH+ during grazing-angle scattering from a KCl (001) surface are measured. The surface of KCl (001) is heated at 180°C and the beam current is kept lower than 1 fA to prevent macroscopic surface charging. The angular distribution of the fragment protons shows a well-defined peak similarly to the grazing-angle scattering of atomic ions. The observed peak, however, is shifted from the specular angle toward larger scattering angles. The observed angular shift for the trailing proton is larger than that for the leading proton. These results clearly indicate that the motion of the fragment protons is affected by the surface track potential induced by the partner He ion. 1050-2947 2 PHYSICAL REVIEW A http://link.aps.org/doi/10.1103/PhysRevA.82.022901 82 AMER PHYSICAL SOC Direct evidence of the surface track potential 2433/147050 Watanabe, Shun N. 2011/07/30 We observed the photophoresis of smoke particles in a small focal laser beam under micro-gravity, exerted in an airplane, to avoid air convectional flow due to buoyancy. We measured the motion of smoke particles and found that the particles exhibit negative photophoresis under the suppression of the convection. Based on the distribution of velocity of negative photophoresis, it is shown that the photophoretic velocity is proportional to the laser power applied for the particle. We discuss the mechanism in terms of the radiometric force. 451 0009-2614 4-6 Chemical Physics Letters 447 511 Elsevier B.V.

Adequate laryngeal exposure is essential, but in some cases sufficient view of the glottis cannot be obtained, leading to treatment failure. This study reports how to manage vocal fold lesions in difficult laryngeal exposure (DLE) cases. [Methods]From 2003 to 2009, 212 patients underwent endolaryngeal microsurgery at Kyoto Medical Center and Kyoto University Hospital. Phonomicrosurgery was performed under sniffing (Boyce–Jackson) position with triangular shaped laryngoscope for laryngeal exposure. However, in DLE cases, the posture and laryngoscope were modified as needed to adequately expose the lesion. Fiberoptic laryngeal surgery (FLS) with local anesthesia was also used for the most difficult cases. [Results]The number of the patients with DLE was 14 (6.6%). Endolaryngeal microsurgery was possible in DLE cases by selecting the appropriate posture and laryngoscope. However, the procedure could not be completed in two patients with an anterior web and a vocal fold cyst, both of which required a subsequent revision procedure. Fiberoptic laryngeal surgery with topical anesthesia was a feasible alternative for these cases. [Conclusions]Phonosurgery was possible even in DLE cases. It is important to modify the setup of direct laryngoscopy as needed to obtain adequate exposure. Fiberoptic surgery may also be used in certain difficult cases. 380 0385-8146 3 Auris nasus larynx 373 38 Elsevier Ireland Ltd.

To investigate the proton transport property, a series of photocurable electrolytes with various PI content ratios were prepared to form photocured membranes. Water uptake, ion exchange capacity (IEC), proton conductivity, and water-resistance of the photocured membranes were investigated. Water-resistant photocured membrane is easy to prepare, which gives relatively high proton conductivity (28 mS cm[−1] under 70 °C and relative humidity of 90%). Patterning of micro-structure on the photocured membrane was also demonstrated by using the property of the photocurable electrolytes. 40 0167-2738 Solid State Ionics 35 204-205 Elsevier B.V.

Cu grain growth was rapid on a barrierless SiO2/Si substrate and very slow on a Ta barrier due to strong (1 1 1) texture. The growth rate and the average grain diameter after being kept at RT for up to ∼60 days were maximum at a (2 0 0)Cu peak to (2 2 2)Cu peak area ratio of ∼1.0, where {1 1 1}, {1 0 0} and {5 1 1} grains coexisted. Such coexistence of three or more orientations of grains is essential in facilitating Cu grain growth at RT. Similarly, the average twin boundary (TB) density was maximum when Cu grain growth was facilitated. TB formation in nano-sized Cu grains was not controlled by grain size, but due to grain growth. The TB could be annealing twins caused by irregularities in the stacking sequence during relatively fast grain growth. The Cu film texture is concluded to be determined at the beginning of deposition, and the wettability of various barrier materials by the Cu films plays a key role in determining the film texture. 595 1359-6454 2 Acta Materialia 588 60 Elsevier Ltd.

Liquid crystalline mesophase with a smectic A interdigitated bilayer structure is observed for the salt with x ≥ 14, showing a fan-like or focal conic texture. Temperature range of the mesophase increases with increase in alkyl chain length (from 26.7 °C for C14MPyr(FH)2F to 90.7 °C for C18MPyr(FH)2F). The layer spacing in the smectic structure monotonously increases with increasing alkyl chain length and decreases with increasing temperature. The liquid crystalline mesophase of C14MPyr(FH)2F exhibits anisotropy in ionic conductivity and the ionic conductivity parallel to the smectic layer is roughly ten times larger than that perpendicular to the smectic layer. 349 0022-1139 Journal of Fluorine Chemistry 344 135 Elsevier B.V.

In this study, we evaluated the effect of topical fucoxanthin on UVB-induced skin photoaging in hairless mice. The dorsal skins were treated topically with a 0.001% fucoxanthin solution 2 h each time before UVB irradiation (5 times a week) for 10 weeks. The formation of wrinkles in UVB-irradiated skin treated with vehicle alone significantly increased, as compared with the non-irradiated control. Treatment with fucoxanthin tended to suppress UVB-induced wrinkle formation, but there was no significant difference between wrinkle formation in the control group and the fucoxanthin treatment group. However, topical treatment with fucoxanthin significantly lessened UVB-induced epidermal hypertrophy, VEGF, and MMP-13 expression in the epidermis and thiobarbituric acid reactive substances (TBARS) in the skin. These results indicate that topical treatment with fucoxanthin prevents skin photoaging in UVB-irradiated hairless mice, possibly via antioxidant and antiangiogenic effects. 760 0916-8451 4 Bioscience, Biotechnology, and Biochemistry 757 https://www.jstage.jst.go.jp/article/bbb/75/4/75_110040/_article 75 Japan Society for Bioscience, Biotechnology, and Agrochemistry fucoxanthin Protective Effect of Fucoxanthin against UVB-Induced Skin Photoaging in Hairless Mice 2433/156418 IZAWA, Kunihiko 2004/07/21 341 0452-9987 4 Contributions from the Biological Laboratory, Kyoto University 329 29 京都大学大学院人間・環境学研究科 The copepodid and two chalimus stages of Caligus latigenitalis Shiino, 1954 (Copepoda, Siphonostomatoida, Caligidae), parasitic on Japanese black sea bream, Acanthopagrus schlegeli 2433/76190 Matsuoka, Saburo 1967/03/31 20 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 12 45 Institute for Chemical Research, Kyoto University Lethal Effect of Gamma Irradiation on Euglena Cells in Two Differrent Growth Phases (Special Issue on Physical, Chemical and Biological Effects of Gamma Radiation, VIII) 2433/76195 Odani, Hisashi 1967/07/20 131 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 122 45 Institute for Chemical Research, Kyoto University Tensile Creep Behavior of Monodisperse Poly-α-methylstyrene (Special Issue on Polymer Chemistry, IV) 2433/87338 Matsunaga, Ryusuke 2009/08/30 We investigated the magnetic and temperature dependence of the bright and dark exciton luminescence spectra in single carbon nanotubes. We found that the phonon-induced exciton scattering rate from the bright to the dark state is only one order of magnitude larger than the dark exciton recombination rate below 10 K at zero magnetic field. Our results indicate that excitons are nonequilibriumly distributed between the bright and dark states due to the different parities of the wave functions and that Aharonov-Bohm flux enhances the phonon-induced exciton scattering between these two states. Our nonequilibrium exciton distribution model can also explain the nonzero photoluminescence intensity at very low temperatures. 1098-0121 11 Physical Review B 80 American Institute of Physics Aharonov-Bohm effect Symmetry-induced nonequilibrium distributions of bright and dark exciton states in single carbon nanotubes 2433/157233 Asakawa, Harutoshi 2012/05/30 It was ever reported in a communication of this journal that the large crystal grains having “bamboo leaf-like (BL)” morphology were produced by a rapid heating of isotactic polypropylene (iPP) from the mesophase. In order to optimize the condition to generate the BL crystals, heating rate effects on the crystallization behavior from the mesophase of iPP have been studied by utilizing a de-polarized light transmission (DPLT) method. The DPLT sensitively detected not only the cold crystallization from the mesophase around 100–120 °C but also the crystal grain growth in a narrow temperature region just below the melting temperature. With increasing the heating rate, both the temperature regions of the cold crystallization and the crystal grain growth shifted toward the higher temperatures. When the heating rate is slow (<20 °C/min), the crystal grain growth was not conspicuous. With increasing the heating rate, the rate of the crystal grain growth increased and showed a maximum when the heating rate is approximately 60–80 °C/min. However, excessively fast heating (>100 °C/min) also suppressed the crystal grain growth. 2782 0032-3861 13 Polymer 2777 53 Elsevier Ltd.

The RS intensity showed slight enhancement with an increase in the Au NPs, while the PL intensity decreased dramatically. These results were explained by an energy-transfer (ET) model considering weak electromagnetic-enhancement factors estimated from the RS studies and ET rates from CdSe to Au NPs obtained from the time-resolved PL spectra. 1098-0121 15 Physical Review B 78 American Physical Society cadmium compounds Energy transfer in mixed CdSe and Au nanoparticle monolayers studied by simultaneous photoluminescence and Raman spectral measurements 2433/76274 Uehara, Yoshiaki 1969/03/31 153 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 143 47 Institute for Chemical Research, Kyoto University Design and Peformanee of a Broad Range Magnetic Spectrograph 2433/76282 Chu, Hyong-Dong 1968/08/16 221 0023-6071 3 Bulletin of the Institute for Chemical Research, Kyoto University 209 47 Institute for Chemical Research, Kyoto University Some Structures and Properties of Very High Molecular Weight Linear Polyethylene (Special Issue on Polimar Chemistry, VI) 2433/76338 Sakka, Sumio 1970/12/19 197 0023-6071 4-5 Bulletin of the Institute for Chemical Research, Kyoto University 185 48 Institute for Chemical Research, Kyoto University Formation of Tungsten Bronze and Other Electrically Conducting Crystals by Crystallization of Glasses Containing Alkali and Tungsten Oxide 2433/76350 Tanaka, Nobuyuki 1971/03/24 248 0023-6071 6 Bulletin of the Institute for Chemical Research, Kyoto University 236 48 Institute for Chemical Research, Kyoto University Partial Melting, Recrystallization and Thermal Shrinkage of Fibrous Polymers 2433/158288 Ito, Hiroaki 2012/04/29 The spontaneous formation of a thread-like pattern with negatively charged lipids on an oil∕water interface is reported. An analysis of the time-dependent change at the interface observed by fluorescence microscopy revealed that the thread-like pattern is generated through a two-step mechanism. First, inverted lipid micelles in the bulk-oil phase gradually diffuse onto the oil∕water interface. Next, the micelles are adsorbed on the interface and self-assemble to form the thread-like pattern. The essential characteristics of this pattern formation are theoretically reproduced by a simple Monte Carlo simulation that takes into account the kinetics in the coalescence of charged micelles on a 2D interface. 0021-9606 20 The Journal of chemical physics 136 American Institute of Physics adsorbed layers Emergence of a thread-like pattern with charged phospholipids on an oil∕water interface. 2433/86205 Tokita, Shigeki 2009/08/30 We have demonstrated single-shot measurement of electron diffraction patterns for a single-crystal gold foil using 340 keV electron pulses accelerated by intense femtosecond laser pulses with an intensity of 2×1018 W/cm2. The measured electron beam profile is faithfully reproduced by the numerical simulation of the electron trajectory, providing evidence that the electron pulse spontaneously expands in time owing to the velocity spread produced in the acceleration process, but is not distorted in an irreversible nonlinear manner. This study shows that the laser acceleration is promising for the development of pulse compression methods for single-shot femtosecond electron diffraction. 00036951 11 Applied Physics Letters 95 American Institute of Physics Single-shot ultrafast electron diffraction with a laser-accelerated sub-MeV electron pulse 2433/74024 1949/12/20 京都大学化研講演集 19 京都大学化学研究所 COVER, CONTENTS 表紙・化研講演集第19輯目次・編輯後記 2433/145542 Yano, Yoshiaki 2011/07/21 We report a new method for the detection of ligand-induced receptor internalization by fluorescence ratiometric imaging of pH in endosomes in combination with a recently developed posttranslational labeling system based on the formation of a heterodimeric coiled-coil structure. The N-terminus of the β2-adrenergic receptor expressed on the cell surface was doubly labeled with pH-sensitive fluorescein and pH-insensitive tetramethylrhodamine. A significant increase in the tetramethylrhodamine-to-fluorescein fluorescence intensity ratio was observed after incubation with agonists in a concentration-dependent manner. This simple and accurate method of detecting the agonistic activity of receptors will be useful for high-throughput screening of drug candidates. 2388 0014-5793 14 FEBS letters 2385 585 Elsevier B.V.

The field emission scanning electron microscopy (FE-SEM) and electrochemical characterization confirmed the effective attachment of gold nanoparticles on GC surface with such a wet-chemical method. The as-prepared gold nanoparticles attached glassy carbon electrode (Au/GCE) presented excellent catalytic ability toward the oxidation of nitrite. Compared with bare GCE and planar gold electrode, the Au/GCE obviously decreased the overpotential of nitrite oxidation and improved the peak current. The catalytic current was found to be linearly proportional to the nitrite concentration in the range of 1 × 10-5 - 5 × 10-3 M, with a detection limit of 2.4 × 10-6 M. The Au/GCE was successfully applied to the electrochemical determination of nitrite in a real wastewater sample, showing excellent stability and anti-interference ability. 1425 0910-6340 12 Analytical Sciences 1421 23 Japan Society for Analytical Chemistry Electrochemical Determination of Nitrite Using a Gold Nanoparticles-modified Glassy Carbon Electrode Prepared by the Seed-mediated Growth Technique 2433/85308 Kobayashi, Chiyoko 1998/05/30 Ultrastructural and physiological studies have shown that planarian muscles have some characteristics of smooth and some characteristics of striated muscles. To characterize planarian muscles, we isolated two myosin heavy chain genes (DjMHC-A and DjMHC-B) from a planarian, Dugesia japonica, by immunological screening, and analyzed their structures and spatial expression patterns. Structural analysis indicated that both MHC genes are striated-muscle-type myosin genes, although planarian muscles do not have any striation. In situ RNA hybridization showed that expression of the two myosin genes is spatially strictly segregated. DjMHC-A was expressed in pharynx muscles, pharynx cavity muscles, muscles surrounding the intestinal ducts, a subpopulation of body-wall muscles and several muscle cells in the mesenchymal region around the base of the pharynx. DjMHC-B was expressed in body-wall muscles (including circular, diagonal and longitudinal muscles), vertical muscles and horizontally oriented muscles. Double staining with DjMHC-A and -B probes clearly demonstrated that expression of the DjMHC-A and -B genes do not occur in the same cell. During regeneration, the number of cells positive for expression of each gene increased in the blastema region, suggesting that both types of muscle may be involved in blastema formation. DjMHC-B-positive cells disappeared from the body-wall muscle layer in the pharynx-cavity-forming region, whereas DjMHC-A-positive cells were markedly accumulated there, suggesting that the two types of muscle in the body wall layer may have distinct functions. These results indicate that planarians have at least two types of muscle that express striated-muscle-type MHC genes, but do not form striation. 869 0289-0003 6 Zoological Science 861 15 Zoological Society of Japan Identification of two distinct muscles in the planarian Dugesia japonica by their expression of myosin heavy chain genes 2433/85322 Sekimizu, Koshin 2007/06/29 Wild-type medaka are known to have remarkable capabilities of fin, or epimorphic, regeneration. However, a hypothyroid mutant, kamaitachi (kmi), frequently suffers from injury in fins, suggesting an important role of thyroid hormone in fin regeneration. This led us to examine the relationship between thyroid hormone and fin regeneration using medaka as a model. For this, we first set up a medaka experimental system in which the rate of regeneration was statistically analyzed after caudal fin amputation under normal and hypothyroid conditions. As expected, the regeneration of amputated caudal fins was delayed in hypothyroid kmi –/– mutants. We then examined wild-type medaka with thiourea-induced hypothyroidism to evaluate the requirement of thyroid hormone during epimorphic fin regeneration. The results demonstrate that the growth rate of regenerates was much reduced in severely hypothyroid medaka throughout the regeneration period. This reduction in regenerative rate was recovered by exogenous administration of L-thyroxine. The present study is thus the first to report the direct involvement of thyroid hormone in teleost fin regeneration, and provides a basic framework for future molecular and genetic analyses. 699 0289-0003 7 Zoological Science 693 24 Zoological Society of Japan thyroid hormone Defective Fin Regeneration in Medaka Fish (Oryzias latipes) with Hypothyroidism full access 2433/85328 Matsui, Masafumi 2006/12/30 Two forms of Staurois that are differentiated by body size occur parapatrically in the Crocker Range, Sabah, Borneo. Analyses of a total of 1,499 bp of the mitochondrial cytochrome b, 12S rRNA, and 16S rRNA genes revealed that the two forms could be completely split genetically. The two forms could be also clearly differentiated morphologically, not only by snout-vent length but also by the relative sizes of snout, eye, and finger disk. Comparisons of the two forms with all known species of the genus revealed the large and small forms to be S. tuberilinguis and S. parvus, respectively. The latter species has long been synonymized with the former, but we here consider them to represent different species. 106 0289-0003 1 Zoological Science 101 24 Zoological Society of Japan biodiversity Resurrection of Staurois parvus from S. tuberilinguisfrom Borneo (Amphibia, Ranidae) 2433/87131 Azuma, Takashi 2009/10/30 Purpose: The articular cartilage is a small tissue with a matrix structure of three layers between which the orientation of collagen fiber differs. A diffusion-weighted twice-refocused spin-echo echo-planar imaging (SE-EPI) sequence was optimized for the articular cartilage, and the structure of the three layers of human articular cartilage was imaged in vivo from diffusion tensor images. Materials and Methods: The subjects imaged were five specimens of swine femur head after removal of the flesh around the knee joint, five specimens of swine articular cartilage with flesh present and the knee cartilage of five adult male volunteers. Based on diffusion-weighted images in six directions, the mean diffusivity (MD) and the fractional anisotropy (FA) values were calculated. Results: Diffusion tensor images of the articular cartilage were obtained by sequence optimization. The MD and FA value of the specimens (each of five examples) under different conditions were estimated. Although the articular cartilage is a small tissue, the matrix structure of each layer in the articular cartilage was obtained by SE-EPI sequence with GRAPPA. The MD and FA values of swine articular cartilage are different between the synovial fluid and saline. In human articular cartilage, the load of the body weight on the knee had an effect on the FA value of the surface layer of the articular cartilage. Conclusion: This method can be used to create images of the articular cartilage structure, not only in vitro but also in vivo. Therefore, it is suggested that this method should support the elucidation of the in vivo structure and function of the knee joint and might be applied to clinical practice. 1248 0730725X 9 Magnetic Resonance Imaging 1242 27 Elsevier Articular cartilage In vivo structural analysis of articular cartilage using diffusion tensor magnetic resonance imaging 2433/74782 Kimura, Kiichi 1951/02/15 193 The Commemoration volume for the silver jubilee 179 Institute for Chemical Research, Kyoto University THE ARAKATSU AND KIMURA LABORATORIES 2433/86336 Asahi, Takanao 1984/01/23 Kyoto University 低分子量ポリエチレンの六方晶相と融液相 The Hexagonal Phase and Melt of Low Molecular Weight Polyethylene 2433/86412 Ueda, Yasuji 1989/03/23 Kyoto University ニワトリクリスタリンに対するモノクローナル抗体 MONOCLONAL ANTIBODIES TO CHICK CRYSTALLINS 2433/84641 Seko, Atsuto 2008/02/01 The structures and stabilities of a series of nonstoichiometric SnO2-x compounds, which are yet unknown experimentally, are predicted using the cluster expansion technique combined with first-principles calculations.

D. multipapillatum) from four sites off Nakanoshima Island and one site off Takarajima Island. Diplosoma midori (Tokioka, 1954) is a photosymbiotic ascidian that was originally described from Nakanoshima Island and Takarajima Island. Although there is argument as to the taxonomical status of this species, the conditions of the syntype specimens were inadequate for examining detailed features for identification. Based on the topotype specimens from Takarajima Island, we concluded that D. midori should be regarded as an invalid species, and is a junior synonym of D. simile or D. virens. 92 0037-2870 5-6 Publications of the Seto Marine Biological Laboratory 85 40 Seto Marine Biological Laboratory, Kyoto University ascidian-algal symbiosis Photosymbiotic Ascidians from Nakanoshima Island and Takarajima Island (the Tokara Islands, Ryukyu Archipelago, Japan) with Remarks on the Status of Diplosoma midori (Tokioka, 1954)* 2433/143597 Miyake, Masao 2011/07/30 TiAl3 coating was formed on TiAl alloy by Al electrodeposition from a dimethylsulfone (DMSO2) bath and subsequent annealing. Before the Al electrodeposition, anodic dissolution of TiAl substrate in the DMSO2 bath was conducted to remove the surface oxide layer of the TiAl substrate. By performing the Al electrodeposition immediately after the anodic dissolution, uniform Al films adherent to the TiAl substrate could be obtained. Annealing at 650–1000 °C yielded a single TiAl3 layer or two layers of TiAl3 and TiAl2 on the TiAl substrate. The resulted TiAl3 layer was confirmed to show oxidation-resistance at high temperatures. 5146 0257-8972 21-22 Surface and Coatings Technology 5141 205 Elsevier B.V. Electroplating Fabrication of TiAl3 coating on TiAl-based alloy by Al electrodeposition from dimethylsulfone bath and subsequent annealing 2433/84569 Ishikawa, J. 2008/01/30 In this paper heavy negative-ion sources which we developed and their applications for materials science are reviewed. Heavy negative ions can be effectively produced by the ejection of a sputtered atom through the optimally cesiated surface of target with a low work function. Then, enough continuous negative-ion currents for materials-science applications can be obtained. We developed several kinds of sputter-type heavy negative-ion sources such as neutral- and ionized-alkaline metal bombardment-type heavy negative-ion source and rf-plasma sputter type. In the case where a negative ion is irradiated on a material surface, surface charging seldom takes place because incoming negative charge of the negative ion is well balanced with outgoing negative charge of the released secondary electron. In the negative-ion implantation into an insulator or insulated conductive material, high precision implantation processing with charge-up free properties can be achieved. Negative-ion implantation technique, therefore, can be applied to the following novel material processing systems: the surface modification of micrometer-sized powders, the nanoparticle formation in an insulator for the quantum devices, and the nerve cell growth manipulation by precise control of the biocompatibility of polymer surface. When a negative ion with low kinetic energy approaches the solid surface, the kinetic energy causes the interatomic bonding (kinetic bonding), and formation of a metastable material is promoted. Carbon films with high constituent of sp3 bonding, therefore, can be formed by carbon negative-ion beam deposition. 0034-6748 2(Part 2) REVIEW OF SCIENTIFIC INSTRUMENTS http://link.aip.org/link/?RSINAK/79/02C506/1 79 American Institute of Physics Negative-on source applications (invited) 2433/89645 Zhong, Zhihong 2010/09/29 Diffusion bonding between W and ferritic/martensitic steel F82H using a Ti interlayer was carried out in vacuum at temperature range of 850–950 °C for 1 h with 10 MPa. Metallographic analysis with field-emission scanning electron microscopy revealed excellent bonding at both W/Ti and Ti/F82H interfaces. The chemical compositions of the reaction products were analyzed by energy dispersive spectroscopy and their existence were confirmed by X-ray diffraction technique. α–β Ti solid solution was detected at W/Ti interface, while the reaction phases at Ti/F82H interface are dependent on the joining temperature. Joint strength was evaluated and the variations in strength of the joints were significantly related to the microstructural evolution of the diffusion zone. All the joints fractured at Ti/F82H interface during shear testing. The hardness distribution across the joining interfaces was also determined. 551 09258388 2 Journal of Alloys and Compounds 545 489 Elsevier Diffusion bonding Microstructure and mechanical properties of diffusion bonded joints between tungsten and F82H steel using a titanium interlayer 2433/75408 Takahashi, Isao 1954/01/31 18 0023-6071 1 Bulletin of the Institute for Chemical Research, Kyoto University 8 32 Institute for Chemical Research, Kyoto University New Methods of Dielectric Measurement in the Centimeter Wave Region 2433/84661 塩田, 浩平 2004/04/29 平成13-15年度科学研究費補助金 (基盤研究(B)(1))研究成果報告書　課題番号：13557001 研究代表者：塩田浩平(京都大学医学研究科） http://kaken.nii.ac.jp/ja/p/13557001 京都大学 発生学 MR顕微鏡による胎児画像データベースの構築と人体発生学教育研究支援システムの開発 2433/87160 Kim, Sung-Wook 2009/09/29 The alkyl derivatives of boehmite (alkoxyalumoxanes; AlO(OH)1-x (OR) x ) were synthesized by the reaction of aluminum triisopropoxide in straight-chain primary alcohols at 300 °C for 2 h in an autoclave. In the present work, pore structures of aluminas obtained by calcination of the alkyl derivatives of boehmite were examined. The alumina obtained from the ethyl derivative of boehmite had a broad pore-size distribution, while the pore-size of the alumina obtained from the dodecyl derivative of boehmite distributed in a narrow range in the mesopore region. The mode pore diameter of the latter alumina increased with the increase in calcination temperature (as-syn., 39 Å; 600 °C, 54 Å; 800 °C, 58 Å; 1000 °C, 68 Å), but narrow pore-size distribution was maintained even after calcination at high temperatures. 612 13802224 5 Journal of Porous Materials 605 16 Springer Verlag Alumina Pore structure of aluminas derived from the alkyl derivatives of boehmite 2433/89651 Kim, HakHee 2008/08/30 Epigallocatechin-3-O-gallate (EGCG), the major polyphenolic compound present in green tea, has potent anti-oxidant and free radical-scavenging activities. In this study, various concentrations (10, 100, and 1,000 ppm) of EGCG were incorporated into a collagen sponge (CS) in order to investigate its healing effects on full-thickness wounds created in type 2 diabetic mice. After 14 days, the residual wound size of the mice treated with 10 ppm EGCG-incorporated collagen sponge (E-CS) decreased significantly faster than that of the other mice. Moreover, significant increases in the degree of reepithelialization, the thickness of the granulation tissue, and the density of the capillaries were also histologically observed in the wound sites exposed to 10 ppm E-CS in comparison with the others. Furthermore, 10 ppm E-CS resulted in significant increases in the immunoreactivity of Ki-67 (reepithelialization at the wound site), CD31 (formation of blood vessels), and α-smooth muscle actin (the induction of myofibroblasts across the dermis). These results suggest that a CS incorporated with EGCG at low concentrations can enhance wound healing in diabetic mice by accelerating reepithelialization and angiogenesis as well as improving the cellular reorganization of granulation tissue by triggering the activity of myofibroblasts. 720 1067-1927 5 Wound Repair and Regeneration 714 16 Blackwell Publishing / Wound Healing Society Enhanced wound healing by an epigallocatechin gallate-incorporated collagen sponge in diabetic mice 2433/76479 Nemoto, Norio 1973/08/06 130 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 118 51 Institute for Chemical Research, Kyoto University Flow Properties of Copolymer Solutions.

Real-time bioluminescence imaging of Hes1 expression showed that the Hes1 oscillation is robust and stable in the PSM while unstable in most individual fibroblasts and dissociated PSM cells. Thus, the Hes1 oscillators in individual PSM cells and fibroblasts are intrinsically similar, and these results, together with mathematical simulation, suggest that the cell-cell communication is essential not only for synchronization but also for stabilization of cellular oscillators. 1318 1091-6490 5 PNAS : proceedings of the National Academy of Sciences of the United States of America 1313 103 National Academy of Sciences Real-time imaging of the somite segmentation clock: Revelation of unstable oscillators in the individual presomitic mesoderm cells 2433/88756 HAYAKAWA, Tomoyasu 2007/12/30 Titanium (Ti) metal substrates were etched in sulfuric acid (H2SO4) with concentrations of 25, 50, 75 and 97% at 60°C for 30 min. Hydroxyapatite (HA) films were deposited onto unetched and etched substrates by an electrodeposition method under a pulse current. The electrolyte was metastable calcium phosphate solution that had 1.5 times the ion concentrations of human body fluid, but did not contain magnesium ion at 36.5°C. Deposition times were 90 min. We used the average current density of 0.01 A/cm2 and ON time equal to OFF time of 15 s. In the electrodeposition, hydrogen was incorporated into the surface of the Ti substrates to form titanium hydride (TiH2) on the substrate surfaces. After the electrodeposition, all specimens were heated at 600°C for 60 min. The adhesion between apatite and substrates were greatly improved by the heat treatment for the substrates etched in 50 and 75% H2SO4. It is considered that in these specimens the anchoring effect due to the microstructural roughness formed by etching was enhanced by the shrinking of HA crystals during the heat treatment. 73 1882-0743 1349 Journal of the Ceramic Society of Japan 68 116 Ceramic Society of Japan Apatite Coating of hydroxyapatite films on titanium substrates by electrodeposition under pulse current 2433/76563 Nakajima, Akio 1974/09/13 307 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 295 52 Institute for Chemical Research, Kyoto University Micro-Heterophase Structure in Membrane of Vinylpyridine-Styrene-Vinylpyridine Block Copolymers and their Quaternized Products (Commemoration Issue Dedicated to Professor Waichiro Tsuji On the Occasion of his Retirement) 2433/76572 Tamabe, Katsutoshi 1975/01/31 631 0023-6071 4 Bulletin of the Institute for Chemical Research, Kyoto University 616 52 Institute for Chemical Research, Kyoto University Oriented Adsorption of Amino Acids on (001) Nickel Surface 2433/45690 Mayama, H. 2007/07/21 Volume phase transitions of a DNA gel and a single giant DNA chain caused by spermidine3+ (SPD3+) were investigated. The change in volume for the single DNA (V V0 ∼ 10-5) was four orders of magnitude greater than that for the DNA gel (∼ 10-1), while the critical SPD3+ concentration for the gel (1.8 mM) was one order of magnitude greater than that of the single DNA (0.12-0.25 mM) at the same pH 6.86. We tried to describe mean-field theories with virial expansion, which is valid for the coil-globule transition of a single polymer chain, for the volume phase transitions to explain the reason why such marked differences appeared. Considering the degree of the ordering of Kuhn segments arising from the gel network structure together with the chain length of cross-linked polymer chains, the volume phase transitions were described and then the significant differences were reproduced quantitatively. We concluded that the network structure plays a significant role in the volume phase transition of the gel. © 2007 American Institute of Physics. 0021-9606 3 Journal of Chemical Physics 127 American Institute of Physics Marked differences in volume phase transitions between gel and single molecule in DNA 2433/45686 Hase, M. 2006/03/14 Actin filament, F -actin, is a semiflexible polymer with a negative charge, and is one of the main constituents of cell membranes. To clarify the effect of cross talk between a phospholipid membrane and actin filaments in cells, we conducted microscopic observations on the structural changes in actin filaments in a cell-sized (several tens of micrometers in diameter) water droplet coated with a phospholipid membrane such as phosphatidylserine (PS; negatively charged head group) or phosphatidylethanolamine (PE; neutral head group) as a simple model of a living cell membrane. With PS, actin filaments are distributed uniformly in the water phase without adsorption onto the membrane surface between 2 and 6 mM Mg2+, while between 6 and 12 mM Mg2+, actin filaments are adsorbed onto the inner membrane surface. With PE, the actin filaments are uniformly adsorbed onto the inner membrane surface between 2 and 12 mM Mg2+. With both PS and PE membranes, at Mg2+ concentrations higher than 12 mM, thick bundles are formed in the bulk water droplet accompanied by the dissolution of actin filaments from the membrane surface. The attraction between actin filaments and membrane is attributable to an increase in the translational entropy of counterions accompanied by the adsorption of actin filaments onto the membrane surface. These results suggest that a microscopic water droplet coated with phospholipid can serve as an easy-to-handle model of cell membranes. © 2006 American Institute of Physics. 0021-9606 10 Journal of Chemical Physics 124 American Institute of Physics COUNTERION-INDUCED ATTRACTION Structural transition of actin filament in a cell-sized water droplet with a phospholipid membrane 2433/52880 NOGUCHI, Masami 1961/02/27 この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 13 0049-7916 木材研究 : 京都大學木材研究所報告 1 25 京都大學木材研究所 Studies on Static Withdrawal Resistance of Nail : Effect of Driving Method and Time after Driving 2433/137217 Makino, Toshiro 2010/11/29 A new spectrophotometer system is developed for the study of thermal radiation characteristics of real surfaces in thermal engineering environments. The system measures spectra of normal incidence hemispherical reflectance RNH and normal emittance EN in the near-ultraviolet through infrared region of wavelength of 0.30 μm to 11 μm simultaneously and repeatedly with a cycle time of 4 s. The system enables evaluation of the normal incidence absorptance AN in this wide spectral region. Transitions of spectra of specular-finished and rough-finished nickel surfaces in a high-temperature air-oxidation process are measured to demonstrate the performance of the system. Clear interference behaviors are found even in the spectra of hemispherical reflectance RNH and emittance EN of a rough-finished surface. 2294 0195-928X 11-12 International Journal of Thermophysics 2283 31 Springer Science+Business Media, LLC.

The pus contained numerous soft, yellowish-white grains. When pressed between two slides and observed with a phase-contrast microscope, the grains were consisted of septate hyphae 3 to 4μ in width. No spores were found. The hyphae were sensitive to drying, and when dried on the slide their morphology was completely destroyed. Efforts were made to culture the grains on mycological and bacteriological media (87 attempts during 14 months of hospitalization), but the causative fungus could not be grown on any media used. Inoculation of the grains with mucin into mice and guinea pigs intraperitoneally and rabbits intrathoracically failed to produce any lesions, and no organisms were recovered from the organs of these animals. この論文は国立情報学研究所の学術雑誌公開支援事業により電子化されました。 160 0009-3378 1 京都大学結核胸部疾患研究所紀要 155 2 京都大学結核胸部疾患研究所 A CASE OF PULMONARY EMPYEMA CAUSED BY AN UNCULTURABLE FUNGUS <原著>培養不能の真菌による膿胸の 1 例 2433/49159 Yoshikawa, Yuko 2006/01/30 Direct attack to genomic DNA by reactive oxygen species causes various types of lesions, including base modi. cations and strand breaks. The most significant lesion is considered to be an unrepaired double-strand break that can lead to fatal cell damage. We directly observed double-strand breaks of DNA in reconstituted chromatin stained by a fluorescent cyanine dye, YOYO (quinolinium, 1,1 '-[1,3-propanediylbis[(dimethyliminio)-3,1- propanediyl]]bis[4-[(3-methyl-2(3H)-benzoxazolylidene) methyl]]-, tetraiodide), in solution, where YOYO is known to have the ability to photo-cleave DNAs by generating reactive oxygen species. Reconstituted chromatin was assembled from large circular DNA (106 kbp) with core histone proteins. We also investigated the effect of vitamin C ( ascorbic acid) on preventing photo-induced double-strand breaks in a quantitative manner. We found that DNA is protected against double-strand breaks by the addition of ascorbic acid, and this protective effect is dose dependent. The effective kinetic constant of the breakage reaction in the presence of 5 mM ascorbic acid is 20 times lower than that in the absence of ascorbic acid. This protective effect of ascorbic acid in reconstituted chromatin is discussed in relation to the highly compacted polynucleosomal structure. The results highlight the fact that single-molecule observation is a useful tool for studying double-strand breaks in giant DNA and chromatin. 999 0006-3495 3 Biophysical Journal 993 90 Biophysical Society ascorbic acid Protective effect of vitamin C against double-strand breaks in reconstituted chromatin visualized by single-molecule observation 2433/76772 Osaki, Kunihiro 1978/07/20 67 0023-6071 2 Bulletin of the Institute for Chemical Research, Kyoto University 56 56 Institute for Chemical Research, Kyoto University Rheology of Copolymer Solutions V. : A Solution of an SB Block Copolymer in l-Chlorohexadecane (Special Issue on Polymer Chemistry XIII)
