互联网上的蛋白质二维凝胶电泳(2DE)数据库资源

为了有效地实现信息资源的交换和共享 ,很多国际知名的实验室和研究机构均建立了各种蛋白质相关数据库。相对蛋白质序列数据库而言 ,蛋白质双向凝胶电泳 ( Two-dimensional gel electrophoresis,2 DE)图谱数据库分布比较分散。本文介绍了发布蛋白质 2 DE数据的主要研究机构 ,分门别类地作了综合性、哺乳类、植物类、微生物和真菌类等专业蛋白质 2 DE数据库的数据内容、特色评价 ,并对两个 2 DE专业搜索引擎的数据来源、检索功能等方面作了描述与评价。本文最后提出 ,今后蛋白质 2 DE数据库的建设过程中应加强数据的标准化、图谱显示格式的统一化

��[Purpose/significance] Scientific cooperation has become a common phenomenon in research activities, and many research projects have also included teamwork in the scope of assessment of implementation effects. Therefore, it is beneficial to the evaluation and sustainable development of the talents projects to explore the changes in the cooperation relationship before and after their receiving the support and explore the role of Cheung Kong Scholars in team building, international and domestic cooperation.[Method/process] In this study, we take the recipients in 2005 of the Cheung Kong Scholars Award as example and take the Wilcoxon signed rank test method to analyze the changes in the cooperative relationship before and after their receiving the award. The cooperative relationship includes the following aspects:the size of the cooperation social network, the strength of cooperation, the duration of cooperation, the role of cooperation, the strength of international and domestic cooperation. The dataset of this study comprised 83 researchers and 11 522 SCI/SSCI papers published between 1996 and 2015, and the analysis was divided into two 10-year periods-the preaward period (1996-2005) and the postaward period (2006-2015).[Result/conclusion] It is found that the Cheung Kong Scholars have played a leading role in team building, international and domestic cooperation after reviving the award. The scholars significantly increased their cooperation social networks (42 VS. 148) and enhanced their cooperation strength (2.17 VS. 2.45) with their partners in the postaward periods. However, the duration of cooperation between the recipients and their collaborators before and after receiving the award was relatively short, and nearly 70% of the cooperation lasted only one year. Moreover, the scholars' coauthorship patterns changed significantly after receiving the award. In both number and proportion, they became less likely to act as the first author, but more likely to be listed as the last author or corresponding author.
