OBJECTS: Hydrogen has been shown to possess antibacterial effects at high concentrations. In addition, chlorine has a strong bactericidal effect even at low concentrations. Electrolysis is a way to simultaneously generate these two components. However, the concentration of hydrogen/free chlorine mixed water generated through electrolysis decreases quickly. It is predicted that the concentration of hydrogen/free chlorine mixed water will vary depending on the quality of water used. After investigating the optimum generation conditions, the effects of the most stable concentration of hydrogen/free chlorine mixed water on carious tooth fungus were evaluated in vitro. Thus, in this experiment, our goal was to evaluate the effects of hydrogen/free chlorine mixed water on oral bacteria. MATERIALS AND METHODS: Using a device that generates hydrogen/free chlorine through electrolysis, the differences in the concentrations of hydrogen and free chlorine based on electrolysis time were evaluated using tap water. Additionally, various concentration changes due to electrolysis time on the hydrogen/free chlorine mixed water were evaluated. Distilled tap water as a control group, hydrogen/free chlorine mixed water, and commercially available mouthwash were added for 1 minute to cultured Streptococcus mutans and then rinsed out with the culture medium. Bacterial growth (600 nm) and biofilm formation (590 nm) were measured at 3 and 6 hours after the addition of the medium. RESULTS: The concentration of hydrogen/chlorine mixed water produced by electrolysis varied depending on electrolysis time and the water used. The inhibitory effect of bacterial growth was enhanced depending on the chlorine concentration. Regarding the inhibitory effect on biofilm formation, only the mixed water of hydrogen/free chlorine concentration (500 ppb - 1.0 mg/L) had a suppressing effect after 6 hours. CONCLUSION: It was suggested that hydrogen/chlorine mixed water can be easily produced by electrolysis a

White Patch on the Fore-Flipper of Common Minke Whale, as a Potential Morphological Index to Identify Stocks

引用

Open Journal of Animal Sciences 2016年第2期6卷 116-122页

作者： Gen Nakamura Ichiro Kadowaki Shouka Nagatsuka Ryotaro Hayashi Naohisa kanda Mutsuo Goto Luis A. Pastene Hidehiro Kato Laboratory of Cetacean Biology Tokyo University of Marine Science and Technology Tokyo Japan Japan NUS Company Ltd. Tokyo Japan Institute of Cetacean Research Tokyo Japan

Past studies have indicated that there are two different stocks (J and O stocks) in the North Pacific common minke whale Balaenoptera acutorostrata population. These two stocks differ from each other in certain characteristics, such as body size, conception dates, and genetics. However, till date, few studies have investigated differences in the external body appearance between the two stocks. Therefore, in the present study, we focused on the unique white patch on the flipper of this whale species to elucidate inter-stock differences. We used the animals collected from JARPNII research during 2012 and 2013;stock information was determined by microsatellite DNA analysis (n = 220). We focused on the morphological differences in the size and pattern of the white patch on the flipper of each whale. The length of the white patch along the anterior (ventral) margin of the flipper tends to be proportionally larger in O stock. The pattern of the boundary area of the white patch named as the “Grayish Accessary Layer (GAL)” was remarkably different between stocks. Within animals with “no GAL” type, 94% were J stock. Conversely, of animals with GAL expanding over the half the flipper width, 96% were O stock. We concluded from our study that there were clear morphological differences in the flipper color pattern between J and O stocks, which enable to apply widely to other individuals.

＜正＞ Bifacial CIGS solar cell with a ZnO:Al/ZnO/CdS/CIGS/ITO/SLG structure using ITO （Indium Tin Oxide） back contacts have been fabricated. In this contribution, the details of fabrication and performance of bifacial CIGS thin film solar cells are described. The cell performance of the CIGS device was improved by optimizing Ga content in the CIGS layer. A best cell showed total area efficiencies of 12.6% and 7.4% for front and rear side illumination, respectively. This result implies that the maximum equivalent cell efficiency of 20.0% could be obtained when both sides of the bifacial device were illuminated simultaneously under AM1.5, 100 mW/cm2 conditions.

这个大型体育场由一些小直径的木头建成。外立面上覆盖了重叠的多层屋檐，每层屋檐的下面是小直径的木百叶窗，通过这种现代的方式表达了日本传统建筑中的屋檐之美。105毫米的雪松木方是日本最常见的尺寸，这里将其分成三块50毫米的木板来制作百叶窗。百叶窗出现在外立面上的频率和密度是变化的，让屋檐的尺度更加人性化。屋顶采用桁架结构，该结构结合了具有中等横截面的钢梁和层压木材，利用木材的轴向刚度来最大限度地减少屋顶桁架因风或地震而产生的变形。

众所周知,磨矿过程的能量效率随着产品粒度减小而降低。本文根据破碎力学研究了获得超细颗粒的方法。我们把破碎能(粒度化小能)定义为弹性应变能,并计算出破碎能量与颗粒粒度的关系。本文中假设一个100微米颗粒与一个磨矿介质碰撞后其动能完全转变为破碎能,试样要求的破碎冲击速度为13～225米/秒。超细磨矿必须增加磨矿介质与颗粒碰撞几率。根据上述考虑,我们用湿式磨矿获得了平均直径约0.3微米的研磨产品。

AIM： To investigate the in vivo effects of NK2 on liver regeneration after partial hepatectomy （PH）. METHODS： Survival after PH was observed with 21 NK2 transgenic mice and 23 wild-type （WT） mice over 10 d. Liver regeneration was analyzed using histology and immunohistochemistry. Expressions of genes were analyzed using Northern blot analysis, immunoprecipitation and immunoblotting, and reverse transcriptase polymerase chain reaction assay. Kaplan Meier method and the log-rank test were used for analyzing the survival after PH. Differences in the results of immunohistochemistry and percentage of liver regeneration was determined by the Student＇s t-test. RESULTS： More than half of NK2 transgenic mice died within 48 h after PH. After PH, increased deposition of small lipid droplets in hepatocytes was evident and hepatic proliferation was inhibited in NK2 transgenic mice. The hepatic expression and kinase activity of HGF receptor, c-Met, were unchanged among WT mice and NK2 transgenic mice after PH. The expression of tumor necrosis factor-co （TNF-c0 and interleukin-6 （IL-6） in liver tissues were prolonged in NK2 transgenic mice that died after PH. CONCLUSION： Our findings indicate that overexpression of NK2 inhibits liver regeneration after PH.
