Photocatalytic degradation of Acid Blue 62 over CuO-SnO_2 nanocomposite photocatalyst under simulated sunlight

引用

Journal of Environmental Sciences 2007年第9期19卷 1141-1145页

作者： XIA hui-li ZHUANG hui-sheng zhang Tao XIAO Dong-chang College of Environmental Science and Engineering Donghua University Shanghai 201620 China.

The novel CuO-SnO2 nanocomposite oxide photocatalysts were prepared by simple co-precipitation method, and characterized by X- ray diffraction, transmission electron microscopy, N2 adsorption-desorption measurement and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activities of CuO-SnO2, evaluated using the photodegradation of Acid Blue 62 as a probe reaction under the irradiation of Xenon light, were also found to be related to the calcination temperature and the molar ratio of Cu to Sn. The maximum photocatalytic activity of the CuO-SnO2 photocatalyst was observed to be calcined at 500~C for 3 h （the molar ratio of Cu to Sn was 1：1） due to the sample with good crystallization and high surface area. It also showed much higher photocatalytic activity in treatment dye wastewater under simulated sunlight irradiation compared to Degussa P25 TiO2.

Fluorescence quenching and the binding interaction of lumichrome with nucleic acids

引用

Chinese Science Bulletin 2010年第25期55卷 2829-2834页

作者： li hui JIANG ZhiQin zhang RongHua Department of Chemistry Tongji University Shanghai 200092 China

The interaction of lumichrome (LC) as an endogenous fluorescence probe with nucleobases,nucleosides and nucleic acids has been studied by UV-visible absorption,fluorescence spectroscopy,polarized fluorescence and viscosity. The fluorescence of LC was strongly quenched by a series of nucleic acids and their precursors. The influences of the medium,temperature and salt effects on LC-nucleobase and LC-nucleic acid complexes were investigated. The influences of polarized fluorescence,thermal denaturation and viscosity on LC-ctDNA interaction were examined. The results demonstrate that the main binding model of LC-ctDNA includes strong intercalating into the DNA helix chain.

Chemical Research in Chinese Universities 2010年第5期26卷 798-802页

作者： zhang Ai-li LU Jia-hui zhang Na ZHENG Dan zhang Gui-rong TENG li-rong College of life Science Jilin University Changchun 130012 P R. China

A water-soluble polysaccharide（named MCMP） was isolated from the mycelium with high yield mutation Cordyceps militaris by hot-water extraction, deproteinization by sevage, alcohol precipitation, anion-exchange and gel filtration chromatography CL-6B. The polysaccharide contained mannose, rhamnose, galactose and glucose in a molar ratio of 59.36：1：8.31：39.50, of which the average molecular weight is 8100. In our research, Hep-G2 cells, Hela cells and mesangial cells were chosen to determine the anti-tumor activity of the polysaccharide. The results of MTT assay show that polysaccharides of the mutant strain presented inhibitory activity on the cells proliferation after 48 h incubation.

Autophagy in synaptic development,function,and pathology

引用

Neuroscience Bulletin 2015年第4期31卷 416-426页

作者： Dan-Na Shen li-hui zhang Er-Qing Wei Yi Yang Department of Pharmacology Hangzhou Key Laboratory of Medical NeurobiologySchool of MedicineHangzhou Normal University Department of Pharmacology Zhejiang University School of Medicine

In the nervous system, neurons contact each other to form neuronal circuits and drive behavior, relying heavily on synaptic connections. The proper development and growth of synapses allows functional transmission of electrical information between neurons or between neurons and muscle fibers. Defects in synapse-formation or development lead to many diseases. Autophagy, a major determinant of protein turnover, is an essential process that takes place in developing synapses. During the induction of autophagy, proteins and cytoplasmic components are encapsulated in autophagosomes, which fuse with lysosomes to form autolysosomes. The cargoes are subsequently degraded and recycled. However, aberrant autophagic activity may lead to synaptic dysfunction, which is a common pathological characteristic in several disorders. Here, we review the current understanding of autophagy in regulating synaptic development and function. In addition, autophagy-related synaptic dysfunction in human diseases is also summarized.

Journal of Integrative Plant Biology 2006年第10期48卷 1244-1249页

作者： li-Wen Jing Shi-Hua Chen Xiao-li Guo hui zhang Yan-Xiu Zhao Key Laboratory of Plant Stress Research College of Life Sciences Shandong Normal University Jinan 250014 China

Ablotlc stress, such as salt, drought and extreme temperature, can result in enhanced production of reactive oxygen species （ROS）. Plants have developed both enzymatic ROS-scavenging and non-enzymatic ROS-scavenging systems. The major ROS-scavenging enzymes of plants include superoxide dismutase （SOD）, ascorbate peroxldaae （APX）, catalaae （CAT）, glutathione peroxldaae （GPX） and peroxiredoxina （Prxa）. In the present work, we identified a gene encoding chloroplast-located peroxiredoxin Q, SsPrxQ, from Suaeda salsa L. located at chloroplast. Overexpression of SsPrxQ In Arabidopsis leads to an increase In salt and low-temperature tolerance.
