Commercialization of Zn-metal anodes with low cost and high theoretical capacity is hindered by the poor reversibility caused by dendrites growth,side reactions,and the slow Zn^(2+)-transport and reaction ***,a reversible heterogeneous electrode of Zn-nanocrystallites/polyvinylphosphonic acrylamide(Zn/PPAm)with fast electrochemical kinetics is designed for the first time:phosphonic acid groups with strong polarity and chelation effect ensure structural reversibility and stability of the threedimensional Zn-storage-host PPAm network and the Zn/PPAm hybrid;hydrophobic carbon chains suppress side reactions such as hydrogen evolution and corrosion;weak electron-donating amide groups constitute Zn^(2+)-transport channels and promote“desolvation”and“solvation”effects of Zn^(2+)by dragging the PPAm network on the Zn-metal surface to compress/stretch during Zn plating/stripping,respectively;and the heterostructure and Zn nanocrystallites suppress dendrite growth and enhance electrochemical reactivity,***,the Zn/PPAm electrode shows cycle reversibility of over 6000 h with a hysteresis voltage as low as 31 mv in symmetrical cells and excellent durability and flexibility in fiber-shaped batteries.

氨基末端脑钠尿肽前体(N-terminal pro-B-type natriuretic peptide,NT-proBNP)是心房颠动的危险因素,是用于检测心力衰竭的心脏功能标志物。鉴于心脏功能障碍与脑卒中之间的关系,NT-proBNP是脑卒中风险的候选标志物。该研究旨在评估NT-proBNP与脑卒中的相关性。方法:基于欧洲联盟心血管病风险评估研究的生物标志物,研究人员分析了来自6个社区队列无脑卒中的58173名参与者(50%男性;平均年龄52岁)数据。NT-proBNP测量在欧洲心血管病风险评估中心生物标志物实验室中进行。主要观察结果是脑卒中和脑卒中的亚型(缺血/出血)。结果显示,在随访7.9年(中位数)期间,共观察到1550例脑卒中事件(1176例为缺血性)。NT-proBNP四分位数增加与脑卒中风险增加相关(调整风险因素和心脏病后行多因素Cox回归分析显示趋势P<0.01)。
