2Dietary advanced glycation end-products aggravate non-alcoholic fatty liver disease显示文摘AIM To determine if manipulation of dietary advanced glycation end product(AGE), intake affects nonalcoholic fatty liver disease(NAFLD) progression and whether these effects are mediated via RAGE. METHODS Male C57Bl6 mice were fed a high fat, high fructose, high cholesterol(HFHC) diet for 33 wk and compared with animals on normal chow. A third group were given a HFHC diet that was high in AGEs. Another group was given a HFHC diet that was marinated in vinegar to prevent the formation of AGEs. In a second experiment, RAGE KO animals were fed a HFHC diet or a high AGE HFHC diet and compared with wildtype controls. Hepatic biochemistry, histology, picrosirius red morphometry and hepatic mR NA were determined. RESULTS Long-term consumption of the HFHC diet generated significant steatohepatitis and fibrosis after 33 wk. In this model, hepatic 4-hydroxynonenal content(a marker of chronic oxidative stress), hepatocyte ballooning, picrosirius red staining, α-smooth muscle actin and collagen type 1A gene expression were all significantly increased. Increasing the AGE content of the HFHC diet by baking further increased these markers of liver damage, but this was abrogated by pre-marination in acetic acid. In response to the HFHC diet, RAGE-/-animals developed NASH of similar severity to RAGE+/+ animals but were protected from the additional harmful effects of the high AGE containing diet. Studies in isolated Kupffer cells showed that AGEs increase cell proliferation and oxidative stress, providing a likely mechanism through which these compounds contribute to liver injury. CONCLUSION In the HFHC model of NAFLD, manipulation of dietary AGEs modulates liver injury, inflammation, and liver fibrosis via a RAGE dependent pathway. This suggests that pharmacological and dietary strategies targeting the AGE/RAGE pathway could slow the progression of NAFLD.Christopher Leung Chandana B Herath Zhiyuan Jia Sof Andrikopoulos Bronwyn E Brown Michael J Davies Leni R Rivera John B Furness Josephine M Forbes Peter W Angus 2016World Journal of Gastroenterology2016,22,35:7
3SLIPS-TENG: robust triboelectric nanogenerator with optical and charge transparency using a slippery interface显示文摘Energy harvesting devices that prosper in harsh environments are highly demanded in a wide range of applications ranging from wearable and biomedical devices to self-powered and intelligent systems.Particularly,over the past several years,the innovation of triboelectric nanogenerators(TENGs)that efficiently convert ambient kinetic energy of water droplets or wave power to electricity has received growing attention.One of the main bottlenecks for the practical implications of such devices originates from the fast degradation of the physiochemical properties of interfacial materials under harsh environments.To overcome these challenges,here we report the design of a novel slippery lubricant-impregnated porous surface(SLIPS)based TENG,referred to as SLIPS-TENG,which exhibits many distinctive advantages over conventional design including optical transparency,configurability,self-cleaning,flexibility,and power generation stability,in a wide range of working environments.Unexpectedly,the slippery and configurable lubricant layer not only serves as a unique substrate for liquid/droplet transport and optical transmission,but also for efficient charge transfer.Moreover,we show that there exists a critical thickness in the liquid layer,below which the triboelectric effect is almost identical to that without the presence of such a liquid film.Such an intriguing charge transparency behavior is reminiscent of the wetting transparency and van der Waals potential transparency of graphene previously reported,though the fundamental mechanism remains to be elucidated.We envision that the marriage of these two seemingly totally different arenas(SLIPS and TENG)provides a paradigm shift in the design of robust and versatile energy devices that can be used as a clean and longer-lifetime alternative in various working environments.Wanghuai Xu Xiaofeng Zhou Chonglei Hao Huanxi Zheng Yuan Liu Xiantong Yan Zhengbao Yang Michael Leung Xiao Cheng Zeng Ronald X.

9染料敏化太阳电池纳米结构对输出特性的影响显示文摘根据电子在半导体中的扩散方程,对纳米TiO2染料光敏化太阳电池(DSSC)的输出特性(J-V)进行了研究。多孔薄膜TiO2孔隙率(P)直接影响敏化电极光吸收系数(a)以及电子扩散系数(D),将P与a及D的关系式代入扩散方程,得到了电极纳米结构(孔隙率)对电池输出特性(J-V)影响的计算模型。在光电极孔隙率的实验范围(0.41~0.71),进行了模型分析。研究表明,在孔隙率0.41~0.71的范围内,开路电压(VOC)随P值增大基本保持不变,而短路电流(ISC)则随P值增大而明显减小,因此电池的最大输出功率减小,为获得最大输出功率,P应该控制在0.41~0.5。数值模拟与实验数据进行比较,两者符合良好,从而验证了所建立的模型。倪萌 LEUNG Michael 2006电源技术2006,30,9:2

11基底对染料敏化太阳电池J-U特性的影响显示文摘根据肖特基理论和电子在半导体中的扩散理论,建立了模拟染料敏化太阳电池(DSSC)J-U特性的理论模型,分析了透明导电氧化物(TCO)基底材料的选择对J-U特性的影响。研究表明,TCO与TiO2界面形成的肖特基结对DSSC开路电压(UOC)和短路电流密度(JSC)没有影响,但对填充因子(Fillfactor)有较大影响。当TiO2/TCO的肖特基势垒(Eb)大于0.6eV时,DSSC的最大功率输出值随Eb的增大而明显降低。模型结果与文献报道的实验结果一致。该模型研究为DSSC基底材料的选取提供了理论依据,并适用于除TiO2之外的其他半导体材料。倪萌 LEUNG Michael 2006电源技术2006,30,8:2
