Anthropometric measurements, e.g., body weight （BW）, body mass index （BMI）, as well as serum prostate-specific antigen （PSA） and percent-free PSA （%fPSA） have been shown to have positive correlations with total prostate volume （TPV）. We developed an equation and nomogram for estimating TPV, incorporating these predictors in men with benign prostatic hyperplasia （BPH）. A total of 1852 men, including 1113 at Tokyo Medical and Dental University （TMDU） Hospital as a training set and 739 at Cancer Institute Hospital （CIH） as a validation set, with PSA levels of up to 20 ng m1-1, who underwent extended prostate biopsy and were proved to have BPH, were enrolled in this study. We developed an equation for continuously coded TPV and a logistic regression-based nomogram for estimating a TPV grater than 40 mh Predictive accuracy and performance characteristics were assessed using an area under the receiver operating characteristics curve （AUC） and calibration plots. The final linear regression model indicated age, PSA, %fPSA and BW as independent predictors of continuously coded TPV. For predictions in the training set, the multiple correlation coefficient was increased from 0.38 for PSA alone to 0.60 in the final model. We developed a novel nomogram incorporating age, PSA, %fPSA and BW for estimating TPV greater than 40 mh External validation confirmed its predictive accuracy, with AUC value of 0.764. Calibration plots showed good agreement between predicted probability and observed proportion. In conclusion, TPV can be easily estimated using these four independent predictors.

Species-dependent effects of the phenolic herbicide ioxynil with potential thyroid hormone disrupting activity: modulation of its cellular uptake and activity by interaction with serum thyroid hormone-binding proteins

引用

Journal of Environmental Sciences 2012年第5期24卷 949-955页

作者： sakura Akiyoshi Gobun Sai Kiyoshi Yamauchi Department of Biological Science Faculty of Science Shizuoka University

Ioxynil, a phenolic herbicide, is known to exert thyroid hormone （TH） disrupting activity by interfering with TH-binding to plasma proteins and a step of the cellular TH-signaling pathway in restricted animal species. However, comparative studies are still lacking on the TH disruption. We investigated the interaction of [125I] ioxynil with serum proteins from rainbow trout, bullfrog, chicken, pig, rat, and mouse, using native polyacrylamide gel electrophoresis. Candidate ioxynil-binding proteins, which included lipoproteins, albumin and transthyretin （TTR）, differed among the vertebrates tested. Rainbow trout and bullfrog tadpole serum had the lowest binding activity for ioxynil, whereas the eutherian serum had the highest binding activity. The cellular uptake of, and response to, ioxynil were suppressed by rat serum greater than by tadpole serum. The cellular uptake of [125I]ioxynil competed strongly with phenols with a single ring, but not with THs. Our results suggested that ioxynil interferes with TH homeostasis in plasma and with a step of cellular TH-signaling pathway other than TH-uptake system, in a species-specific manner.

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2023年第12期24卷 1069-1092页

Abiotic stresses, predominately drought, heat, salinity, cold, and waterlogging, adversely affect cereal crops. They limit barley production worldwide and cause huge economic losses. In barley, functional genes under various stresses have been identified over the years and genetic improvement to stress tolerance has taken a new turn with the introduction of modern geneediting platforms. In particular, clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated protein 9(Cas9) is a robust and versatile tool for precise mutation creation and trait improvement. In this review, we highlight the stress-affected regions and the corresponding economic losses among the main barley producers. We collate about 150 key genes associated with stress tolerance and combine them into a single physical map for potential breeding practices. We also overview the applications of precise base editing, prime editing, and multiplexing technologies for targeted trait modification, and discuss current challenges including high-throughput mutant genotyping and genotype dependency in genetic transformation to promote commercial breeding. The listed genes counteract key stresses such as drought, salinity, and nutrient deficiency, and the potential application of the respective gene-editing technologies will provide insight into barley improvement for climate resilience.

Low Pressure Chemical Vapor Deposition of TiO2Layer in Hydrogen-Ambient

引用

Journal of Crystallization Process and Technology 2014年第4期4卷 185-192页

作者： Satoshi Yamauchi Kazuhiro Ishibashi sakura Hatakeyama Department of Biomolecular Functional Engineering Ibaraki University Hitachi Japan

Low pressure chemical vapor deposition (LPCVD) of anatase TiO2?as a reduction gas was demonstrated at pres- sure of 3 mtorr in comparison to that using TTIP and O2 with study for the property of the layers. Dissociation energy of TTIP in H2 was higher than that in O2 but resistivity of the layer deposited in H2 was significantly decreased to 0.2 Ω cm in contrast to the high resistivity beyond 100 Ω cm of the layer deposited in O2. UV-Vis optical transmission spectra showed absorption around 2.2 eV was increased in the layer deposited by TTIP + H2 in addition to decrease of forbidden energy gap due to increase of Urbach tail. Resistivity at low temperature below 100 K indicating the layer deposited in H2-ambient was degenerated by the high electron density but the resistivity was decreased with temperature above 100 K with the activation energy about 100 meV. A possible electronic conduction model based on kernel, grain boundary and surface trap to clarify the temperature dependent resistivity suggesting resistivity of the layer was limited by depletion region in the grain-boundary extended from the surface and the kernel with significantly low resistivity in 10-3 Ω cm order was formed in the layer.

Enhanced Photo-Induced Property of LPCVD-TiO2Layer on PCVD-TiOxInitial Layer

引用

Journal of Materials Science and Chemical Engineering 2015年第7期3卷 28-38页

作者： Satoshi Yamauchi Keisuke Yamamoto sakura Hatakeyama Department of Biomolecular Functional Engineering Hitachi Japan

Plasma-assisted chemical vapor deposition (PCVD) was applied for amorphous TiOx deposition on Pyrex-glass substrate at low temperature below 90°C to control orientation of anatase-TiO2 layer by low pressure chemical vapor deposition (LPCVD) using TTIP-single precursor. Preferentially -oriented anatase-TiO2 layer was successfully deposited with the orientation ratio as high as 68% on the initial layer of the thickness around 70 nm. Contact angle water was quickly decreased by UV-irradiation on the highly -oriented TiO2 layer comparing with the layer directly deposited on glass, whereas surface roughness on the former was significantly reduced in comparison to that on the latter. Methyleneblue (MB) aqueous solution with the concentration of 2 mmol/L was used to evaluate photocatalytic property on the layer. Rate constant of MB-decomposition via first order kinetics increased with the orientation ratio above 60% was resulted in 2.3 × 10-1?min-1 for the layer with -orientation ratio of 68%, whereas the constant was 2.8 × 10-3 min-1 for the layer directly deposited on glass.

Low Resistive TiO2Deposition by LPCVD Using TTIP and NbF5in Hydrogen-Ambient

引用

Journal of Crystallization Process and Technology 2015年第1期5卷 15-23页

作者： Satoshi Yamauchi Kazuhiro Ishibashi sakura Hatakeyama Department of Biomolecular Functional Engineering Ibaraki University Hitachi Japan

Low resistive TiO2 layer was deposited by low pressure chemical vapor deposition (LPCVD) at pressure around 0.25 Pa using titanium-tetra-iso-propoxide (TTIP) and NbF5 in H2-ambient. Acti-vation energy for the deposition rate on the temperature was significantly decreased to 120 kJ/mol as compared with 228 kJ/mol for the deposition in H2 without NbF5. The deposition rate linearly increased with NbF5 supply rate but gradually decreased with H2 supply rate indicated that F on the deposition surface acts as catalyst for TTIP-dissociation but is non-activated by hydrogen. Resistivity of the layer was decreased by NbF5 supply depending on the deposition temperature with the activation energy of 319 kJ/mol, whereas the energy was 244 kJ/mol for the layer deposited in H2 without NbF5. The dependence of resistivity on NbF5. and H2 supply rates suggested that the doping should be performed by sufficient NbF5 and H2 supply rate to improve the crystallinity. As a result of the optimization, the resistivity was successfully reduced to 5 × 10-2 Ω·cm. Optical transmission spectra in UV-Vis region indicated that significant absorption observed for the layer deposited in H2 was notably decreased by using NbF5. The improved optical property was better than that for the layer deposited in O2-ambient.

Drastic Resistivity Reduction of CVD-TiO2Layers by Post-Wet-Treatment in HCl Solution

引用

Journal of Crystallization Process and Technology 2015年第1期5卷 24-30页

作者： Satoshi Yamauchi Kazuhiro Ishibashi sakura Hatakeyama Department of Biomolecular Functional Engineering Ibaraki University Hitachi Japan

Poly-crystalline anatase TiO2 layer fabricated by LPCVD using titanium-tetra-iso-propoxide and NbF5 in H2-ambient was treated in conc.-HCl solution after thin layer of IIIb-group metal was deposited on the TiO2 layer. Resistivity of the as-deposited layer about 1 × 10-1 Ω·cm was drastically reduced to 3 × 10-3 Ω·cm by the wet-treatment using indium. Temperature dependence of the resistivity increased with temperature above 100 K for the wet-treated layer was quite different from that decreased above 100 K for the as-deposited layer, whereas the resistivity was saturated at lower temperatures. The resistivity at room-temperature was decreased with the thickness before the wet-treatment but independent on the thickness above 100 nm for the wet-treated layer. Indium was more effective for the resistivity reduction than gallium but aluminum was not useful for the treatment. As the results that the wet-treatment using indium was examined for the TiO2 layers deposited by various conditions, the optimum deposition condition to reduce the resistivity of the layer after the wet-treatment was clearly different from that for the as-deposited layer.

Food and Nutrition Sciences 2018年第11期9卷 1316-1326页

作者： sakura Tanaka Daichi Yamaguchi Shoji Igawa Department of Sport Science College of Sport Sciences Nippon Sport Science University Kamoshida-Cho Japan

In this study, we investigated the effect of sodium bicarbonate (NaHCO3) supplementation at a dose of 0.2 g·kg−1 40 min before an exercise on intermittent endurance performance and gastrointestinal distress. The participants were six healthy male students of a university. The Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2) was used for the evaluation of intermittent endurance. The participants ingested water (Cont) or NaHCO3 independently at three timings. After drinking water, the Yo-Yo IR1 was performed for 2 min as warm-up. After resting for 5 min, the Yo-Yo IR2 was initiated. The measurement items were exercise distance, nutrition intake, biochemical test results, and blood gas analysis findings. The participants who ingested NaHCO3 had a 14% extended distance than those who ingested Cont, and 2/3 of those who took NaHCO3 showed a better motor performance. No significant difference was observed between the participants who took Cont and NaHCO3 in terms of pH level at baseline, and the NaHCO3 level was significantly higher during pre- and post-exercise (p 3 in terms of bicarbonate ion level at baseline, and the NaHCO3 level was significantly higher during pre- and post-exercise (p 3 at a low dose (0.2 g·kg−1), their exercise ability during an intermittent endurance test has improved. Furthermore, when digestive absorption is considered, eating a meal in advance may be able to suppress the onset of gastrointestinal distress.
