1Improvement of Properties of Pseudomonas sp.Lipase in Resolution of 2-Octanol显示文摘A novel preparation method was developed to form a surfactant-lipase complex for the resolution of 2-octanol in a solvent-free system. The E value was improved from 6.64 to 120.2. The lipase modified by the anionic surfactant possessed a low solubility in the solvent-free system, which was beneficial to the recovery and the repeated usage of the lipase. The surfactant-lipase complex maintained a high enantioselectivity after five cycles of usage. The effect of water on both the activity and the enantioselectivity of the lipase has also been investigated; the direct addition of a salt hydrate pair of Na 4P 2O 7·H 2O and Na 4P 2O 7 can dramatically activate the modified enzyme.WANGZhi QUANJing WENGLiang ZHENGLiang-yu LIUNing DONGHuan CAOShu-gui 2003Chemical Research in Chinese Universities2003,19,4:3

6“烧狗”事件引出“狗权”与“人权”之争——尽快出台《动物福利法》再次引起人们热议显示文摘在小区花园内安家的三只流浪狗的吠叫声影响了一位居民的休息,她一气之下和丈夫雇人将狗堵在洞内,用汽油欲将狗活活烧死。结果一只小狗被烧死,狗妈妈和另一只小狗被严重烧伤。烧狗夫妇的行为引发无数市民和网友的愤恨,他们运用多种方法向其讨伐、责骂,乃至去烧狗夫妇工作单位对其围追堵截,并上书市长要求对其进行开除公职处分。但也有人为烧狗夫妇鸣不平,认为人权毕竟大于狗权。当人的权利受到动物侵害的时候,谁的权利更应该得到保护?智敏 quanjing 2007法治与社会2007,,8:1

9Layered CuNi-Cu_(2)O/NiAlO_(x) nanocatalyst for rapid conversion of p-nitrophenol to p-aminophenol显示文摘In order to well arrange active sites and avoid byproducts, the reasonable structured carrier nanocatalyst plays a crucial role in high catalytic performance, but still remains a challenge. Herein, the layered CuNi-Cu_(2)O/NiAlO_(x) nanosheets have been constructed through hydrothermal synthesis followed by calcination and H_(2) reduction treatment process. The in-situ formed CuNi nanoalloys (NAs) and nano-Cu_(2)O were evenly distributed on the bilateral surface of layered NiAlOx nanosheets. Based on the planar structure of nanosheet, the synergy between catalytic active CuNi NAs and photocatalytic active nano-Cu_(2)O endows CuNi-Cu_(2)O/NiAlO_(x) nanosheets with rapid conversion efficiency for catalyzing p-nitrophenol (p-NP, 14 mg·L^(−1)) to p-aminophenol (p-AP) in 32 s with the reaction rate constant k up to 0.1779 s−1, and no obvious performance decay can be observed even over 27 cycles. Moreover, high concentration of p-NP at 10 and 20 g·L^(−1) could be reduced to p-AP within 14 and 20 min, respectively. Such designed nanoalloy/bimetal-oxide heterostructure can provide a solution for rapid conversion of aminoaromatics from nitroaromatics wastewater even at a large concentration range.Lin Fu Wei Zhou Ming Wen Qingsheng Wu Weiying Li Dandan Wu Quanjing Zhu Jiaqi Ran Panpan Ren 2021Nano Research2021,14,12:1

13Mechanical stretching of 3D hydrogels for neural stem cell differentiation显示文摘While it is known that mechanical dynamics are influential in neural differentiation for critical processes like neurogenesis or neurodegeneration, studies on neural stem cell therapies usually focus on biochemical interactions rather than mechanical aspects, frequently resulting in low efficacy and unfulfilled potential. Therefore, current studies are attempting to elucidate the effect of mechanical stimulus on neural performance using conventional two-dimensional(2D) planar substrates. Yet, these2D substrates fail to capture the defining three-dimensional(3D) characteristics of the in vivo neural stem cell environment.To complete this research gap, we synthesized a series of soft and elastic 3D hydrogels to mimic the neural tissue mechanical environment for 3D cell culture, using long-chain polyethylene glycol diacrylate(PEGDA) and gelatin-methacryloyl(Gel MA).By varying the concentration of the polymer, we obtained biomimicking hydrogels with a tensile modulus as low as 10 k Pa and a compressive modulus as low as 0.8 k Pa. The in vitro results demonstrated that Gel MA-PEGDA hydrogels have the high biocompatibility required to support neural cell growth, proliferation, and differentiation, as well as neurite outgrowth. We then studied the effect of mechanical stretching on the behaviors of neural cells and observed that mechanical stretching could significantly enhance neurite extension and axon elongation. In addition, the neurites were more directionally oriented to the stretching direction. Immunocytochemistry and relative gene expression data also suggested that mechanical tension could upregulate the expression of neural differentiation protein and genes, including GFAP and βIII-Tubulin. Overall, this study shows that in addition to the specific mechanical properties of Gel MA-PEGDA that improve neural differentiation towards specific lineages, hydrogel stretching is also a potentially attractive strategy to improve the therapeutic outcomes of neural stem cell therapies.Quanjing Mei Ho-Yin Yuen Xin Zhao 2022Bio-Design and Manufacturing2022,5,4:1
