| 1 | 知识产权保护对经济增长的作用研究显示文摘实证研究加强知识产权保护是否会促进经济增长。论述知识产权保护与R&D活动以及国际贸易的交互作用,分析其在国家经济增长中发挥的作用,并确定采用R&D知识存量作为R&D活动的代理变量,采用进出口总额占GDP的比重作为国际贸易的代理变量,基于柯布道-格拉斯生产函数构建理论模型,基于影响因素分析推导并建立实证回归模型;依据传统的永续盘存法分别测算固定资本存量和R&D知识存量,利用1980年至2005年27个发达国家和22个发展中国家的面板数据,采用固定效应与随机效应相结合的方法,检验知识产权保护对经济增长的影响效果。实证研究结果表明,加强知识产权保护对经济增长有正向的促进作用,加强知识产权保护和扩大国际贸易对经济增长的促进作用显著,加强知识产权保护和R&D活动对经济增长的促进作用不显著。 | 吴凯 蔡虹 Gary H Jefferson | 2012 | 管理科学2012,25,3: | 15 |
| 2 | Evaluation of three-dimensional biofilms on antibacterial bonding agents containing novel quaternary ammonium methacrylates显示文摘Antibacterial adhesives are promising to inhibit biofilms and secondary caries.The objectives of this study were to synthesize and incorporate quaternary ammonium methacrylates into adhesives,and investigate the alkyl chain length effects on three-dimensional biofilms adherent on adhesives for the first time.Six quaternary ammonium methacrylates with chain lengths of 3,6,9,12,16 and 18were synthesized and incorporated into Scotchbond Multi-Purpose.Streptococcus mutans bacteria were cultured on resin to form biofilms.Confocal laser scanning microscopy was used to measure biofilm thickness,live/dead volumes and live-bacteria percentage vs.distance from resin surface.Biofilm thickness was the greatest for Scotchbond control;it decreased with increasing chain length,reaching a minimum at chain length 16.Live-biofilm volume had a similar trend.Dead-biofilm volume increased with increasing chain length.The adhesive with chain length 9 had 37%live bacteria near resin surface,but close to 100%live bacteria in the biofilm top section.For chain length 16,there were nearly 0%live bacteria throughout the three-dimensional biofilm.In conclusion,strong antibacterial activity was achieved by adding quaternary ammonium into adhesive,with biofilm thickness and live-biofilm volume decreasing as chain length was increased from 3 to 16.Antibacterial adhesives typically only inhibited bacteria close to its surface;however,adhesive with chain length 16 had mostly dead bacteria in the entire three-dimensional biofilm.Antibacterial adhesive with chain length 16 is promising to inhibit biofilms at the margins and combat secondary caries. | Han Zhou Michael D Weir Joseph M Antonucci Gary E Schumacher Xue-Dong Zhou Hockin H K Xu | 2014 | International Journal of Oral Science2014,6,2: | 5 |
| 3 | Mechanisms of autophagy activation in endothelial cell and their targeting during normothermic machine liver perfusion显示文摘Ischaemia-reperfusion injury(IRI) is the leading cause of injury seen in the liver following transplantation. IRI also causes injury following liver surgery and haemodynamic shock. The first cells within the liver to be injured by IRI are the liver sinusoidal endothelial cells(LSEC). Recent evidence suggests that LSEC coordinate and regulates the livers response to a variety of injuries. It is becoming increasingly apparent that the cyto-protective cellular process of autophagy is a key regulator of IRI. In particular LSEC autophagy may be an essential gatekeeper to the development of IRI. The recent availability of liver perfusion devices has allowed for the therapeutic targeting of autophagy to reduce IRI. In particular normothermic machine liver perfusion(NMP-L) allow the delivery of pharmacological agents to donor livers whilst maintaining physiological temperature and hepatic flow rates. In this review we summarise the current understanding of endothelial autophagy and how this may be manipulated during NMP-L to reduce liver IRI. | Yuri L Boteon Richard Laing Hynek Mergental Gary M Reynolds Darius F Mirza Simon C Afford Ricky H Bhogal | 2017 | World Journal of Gastroenterology2017,23,48: | 4 |
| 4 | 非合格种蛋孵化的商品肉鸡生产性能显示文摘集约化商品肉鸡生产企业的目标是每只入舍母鸡能够生产出最大数量的可孵化种蛋和最多的高质量雏鸡。在适当的饲养管理条件下,一只母鸡产蛋可超过180个,鸡肉产量达到270kg。这些生产数据在鸡只之间存在着非常大的差距,其原因可追溯至种蛋的收集标准、储存条件和孵化条件。在坚持种蛋选择与分级的基础上进行常规性的饲养管理,生产企业获得最大收益的目标不难实现。 | 耿慧娟(译) Gary D Butcher Amir H Nilipour | 2006 | 中国家禽2006,28,18: | 3 |
