Analysis of Intermediates and End Products of the Chlorophyll Biosynthetic PathwaySince the 1963 seminal review of Smith and French (62), our understanding of the chlorophyll (chl) biosynthetic pathway has changed dramatically. Several factors have contributed to this phenomenon, among which are: (i) development of systems capable of Chl and thylakoid membrane biosynthesis in organello and in vitro (17,28,42,43......阅读全文

慢性肾脏病是死亡和ESRD相关的危险因素
高血压是慢性肾脏病患者最为常见的共病。但是，肾脏病检测指标——估算肾小球滤过率（eGFR）和白蛋白尿——与死亡或终末期肾脏病（ESRD）的关联是否因高血压的存在与否而不同，目前尚属未知。最近发表于《TheLancet》的一项荟萃分析显示，无论有无高血压，慢性肾脏病均应被视为与死亡和ESRD相关的重要
