Macroautophagy(hereafter referred to as autophagy)is a conserved eukaryotic process,in which dysfunctional proteins,organelles,and other macromolecules are wrapped in intracellular vesicles called autophagosomes and delivered to lysosomes for degradation(Mizushima et al.,2008;Mizushima and Komatsu,2011).Autophagy restores cellular energy and recycles cytoplasmic precursors,sustaining cell homeostasis and cell survival(Mizushima et al.,2008;Mizushima and Komatsu,2011).Elevated autophagy can be detected in both cancer cells and surrounding stromal cells in pancreatic cancer(PC),affecting tumor initiation and progression as well(Yang et al.,2011;Endo et al.,2017).The role of autophagy in PC is highly ***,we illustrate the multifactorial role of autophagy in PC,and the significance of autophagy will be emphasized not only in cancer cells but also in the tumor microenvironment.

Journal of Systems Science & Complexity 2008年第2期21卷 209-216页

作者： Sheng CHEN Lindu zhao ying HAN Institute of Systems Engineering Southeast University Nanjing 210018 China

The authors extend the Gazi＇s swarm model with local neighbor rules and the dynamic communication topology, and study its aggregation properties. Results of analysis show that all agents in the models aggregate and eventually form a cohesive cluster of finite size around the swarm center or the appointed point. Finally, simulations are provided to testify some of the results. Models in the paper are more applicable to the reality for the advantage that each agent only needs the partial information of the entire dynamic system when making motion decision.

Synthesis and Characterization of PEG Polymer Brushes via Cyclopolymerization of 1,2,3-Triazole Tethered Diacrylates

引用

Chinese Journal of Chemical Physics 2015年第6期28卷 -页

作者： Xiao-ying zhao He-wen Liu Key Laboratory of Soft Matter Chemistry Chinese Academy of Sciences Department of Polymer Science and Engineering University of Science and Technology of China Hefei 230026 China

Poly(ethylene glycol) (PEG) macromolecular brushes were synthesized directly via reversible addition-fragmentation chain transfer polymerization cyclopolymerization of diacrylate monomers bearing PEG functional groups through the formation of 11-member rings. The diacrylate monomers bearing PEG functional groups are the 1,2,3-triazole-tethered diacrylate macromolecular monomers with di erent PEG lengths synthesized via the so-called “click” chemistry. The bulky hindrance of PEG chains affected the polymerization behavior of the diacrylate macromolecular monomers, and the diacrylate monomers showed strong tendency to cyclopolymerization rather than crosslinking. NMR analysis and gel permeation chromatography profiles proved the high efficiency of cyclopolymerization without side reactions. The aqueous solutions of the obtained PEG macromolecular brushes were fluorescent under UV excitation. The fluorescence depended dramatically on the concentration of brush-like polymers due to the aggregation of cyclopolymer in water, and could be quenched by the addition of DNA.

Growth and nutrient accumulation of Phragmites australis in relation to water level variation and nutrient loadings in a shallow lake

引用

Journal of Environmental Sciences 2013年第1期25卷 16-25页

作者： ying zhao Xinghui Xia Zhifeng Yang State Key Laboratory of Water Environment Simulation School of EnvironmentBeijing Normal University

Shallow lake eutrophication is a global environmental issue. This study investigated the effects of water level variation and nutrient loadings on the growth and nutrient accumulation of Phragmites australis （reed） by field samplings in Baiyangdian Lake, the largest shallow lake of northern China. The field samplings were conducted in two sites of different nutrient loadings during the whole growth period of reeds, and three types of zones with different water depths were chosen for each site, including the terrestrial zone with water level below the ground, the ecotone zone with the water level varying from belowground to aboveground, and the submerged zone with water level above the ground. The result showed that reed growth was more limited by water level variation than nutrient loadings. The average stem lengths and diameters in terrestrial zones were about 26.3%-27.5% and 7.2%-12.0% higher than those in submerged zones, respectively. Similarly, the terrestrial status increased the aboveground biomass of reeds by 36.6%-51.8% compared with the submerged status. Both the nutrient concentrations and storages in the aboveground reeds were mainly influenced by the nutrient loadings in surface water and sediment rather than the water level variation of the reed growth environment, and the nutrient storages reached their maxima in late August or early September. It was observed that the maximum nitrogen storage occurred in the terrestrial zone with higher nutrient loadings, with the value of 74.5 g/m2. This study suggested that water level variation and nutrient loadings should be considered when using reeds to control and remediate eutrophication of shallow lakes.
