1Hepatitis B virus replication显示文摘Hepadnaviruses,including human hepatitis B virus(HBV),replicate through reverse transcription of an RNAintermediate,the pregenomic RNA(pgRNA).Despite thiskinship to retroviruses,there are fundamental differencesbeyond the fact that hepadnavirions contain DNAinstead of RNA.Most peculiar is the initiation of reversetranscription:it occurs by protein-priming,is strictlycommitted to using an RNA hairpin on the pgRNA,ε,as template,and depends on cellular chaperones;moreover,proper replication can apparently occur onlyin the specialized environment of intact nucleocapsids.This complexity has hampered an in-depth mechanisticunderstanding.The recent successful reconstitution inthe test tube of active replication initiation complexesfrom purified components,for duck HBV(DHBV),now allows for the analysis of the biochemistry ofhepadnaviral replication at the molecular level.Here wereview the current state of knowledge at all steps of thehepadnaviral genome replication cycle,with emphasison new insights that turned up by the use of such cell-free systems.At this time,they can,unfortunately,not be complemented by three-dimensional structurainformation on the involved components.However,atleast for the ε RNA element such information is emerging,raising expectations that combining biophysics withbiochemistry and genetics will soon provide a powerfuintegrated approach for solving the many outstandingquestions.The ultimate,though most challenging goal,will be to visualize the hepadnaviral reverse transcriptasein the act of synthesizing DNA,which will also havestrong implications for drug development.Juergen Beck Michael Nassal 2007World Journal of Gastroenterology2007,13,1:54

3On water security, sustainability, and the water-food-energy-climate nexus显示文摘在持续开发并且在水,食物,精力和气候相互作用的连结的水安全的角色从灰色和 Sadoff 提供的水安全的定义的起点被检验。关于安全的观点的大部分在要求满足人的需要的资源与缺乏的专横有关。因此,在主流的经济的缺乏的处理接着在我们中的每怎么与目的作为个人调解工具的关系被检验,在持续开发的想法的核心的一个过程。根据 Grey-Sadoff 定义,达到水安全数量到作为更多的将军,的一位先锋完成基本的、单个扇区的水开发自立, multi-sectoral 开发。这与水在平等者之中在被当作第一的方法一致,即给予优惠在考虑什么在在水的连结附近完成安全是关键的,食物,精力和气候。当然,城市是为这些要求多重资源精力流动逐渐地被产生的地点。纸讨论安全的二个重要方面,即,资源和服务的存取的差异(例如卫生) 并且在联合 human-built-natural 系统的行为的跳回。关于城市大楼和基础结构计量连结安全,八个伪运作的原则被开发。Michael Bruce BECK Rodrigo VILLARROEL WALKER 2013Frontiers of Environmental Science & Engineering2013,7,5:3
