类泛素蛋白及其中文命名

泛素家族包括泛素及类泛素蛋白,约20种成员蛋白.近年来,泛素家族领域取得了迅猛发展,并已与生物学及医学研究的各个领域相互交叉.泛素家族介导的蛋白质降解和细胞自噬机制的发现分别于2004和2016年获得诺贝尔奖.但是,类泛素蛋白并没有统一规范的中文译名. 2018年4月9日在苏州召开的《泛素家族介导的蛋白质降解和细胞自噬》专著的编委会上,部分作者讨论了类泛素蛋白的中文命名问题,并在随后的\"泛素家族、自噬与疾病\"(Ubiquitinfamily,autophagy anddiseases)苏州会议上提出了类泛素蛋白中文翻译草案,此草案在参加该会议的国内学者及海外华人学者间取得了高度共识.冷泉港亚洲\"泛素家族、自噬与疾病\"苏州会议是由美国冷泉港实验室主办、两年一度、面向全球的英文会议.该会议在海内外华人学者中具有广泛影响,因此,参会华人学者的意见具有一定的代表性.本文介绍了10个类别的类泛素蛋白的中文命名,系统总结了它们的结构特点,并比较了参与各种类泛素化修饰的酶和它们的生物学功能.文章由45名从事该领域研究的专家合作撰写,其中包括中国工程院院士1名,相关学者4名,长江学者3名,国家杰出青年科学基金获得者18名和美国知名高校华人教授4名.他们绝大多数是参加编写即将由科学出版社出版的专著《泛素家族介导的蛋白质降解和细胞自噬》的专家

Heavy metal contents on Futian tidal flat in Shenzhen Bay and their effect on macrobenthos

根据2002年1月和10月在深圳湾福田潮滩同时获得的大型底栖动物和重金属数据进行分析表明,深圳湾福田潮滩Cu、Pb、Zn、Cd含量明显超标.2002年10月Pb、Cd、Cu、Zn含量的平均值比2002年1月高.与历史资料对比,近几年Cu含量有增加趋势.2002年1月,深圳湾福田潮滩奇异稚齿虫密度与沉积物中Pb、Cd、Cu、Zn含量均有显著负相关关系.尖刺缨虫密度与Pb、Cd、Zn含量均有显著负相关关系,与Cu的相关系数也接近显著相关临界值.2002年10月,只有小头虫密度与Cd有显著正相关关系.文中分析了影响重金属与大型底栖动物数量关系的环境因素.According to the data for heavy metals and macrobenthos got on Futian tidal flat in Shenzhen Bay in January and October 2002, the relationship between macrobenthos and heavy metals is analyzed. The results show that contents of Cu,Pb,Zn,Cd are all over the standard values. The mean contents of Cu,Pb,Zn,Cd in October 2002 are all higher than those in January 2002. Cu content has been increasing in past several years compared with history data. In January 2002, there are markedly negative correlation between Cu,Pb,Zn,Cd contents and density of Paraprionospio pinnata. There are markedly negative correlation between Pb,Zn,Cd contents and density of Potamilla acuminata. The correlation coefficient between Cu content and density of Potamilla acuminata is near critical value. In October 2002, there is markedly positive correlation between Cd content and density of Capitella capitata. Environmental factors affecting on quantitative relationship between heavy metals and macrozoobenthos are analyzed in this paper

四种能源草中黄酮类物质的定性研究

本文对杂交狼尾草、柳枝稷、芦竹及象草这4 种能源草的整株、茎和叶中的黄酮类物质总量进行了定量分析,并利用高效液相色谱质谱联用技术对黄酮物质种类进行定性分析.对整株分析的结果表明,柳枝稷的总黄酮含量最高,达到6.84 mg 当量槲皮素/g 干重,比芦竹、杂交狼尾草和象草分别高出59.8%、20.1%和11.2%.能源草的不同部位黄酮分布存在差异,叶中黄酮含量是茎的2.3 - 3.0 倍.杂交狼尾草叶中含量最高,为10.55 mg 当量槲皮素/g 干重.定性分析发现,4 种能源草的提取物中共含有14 种黄酮苷和2 种黄酮醇,包括槲皮苷、异鼠李素和槲皮素.该研究结果可为能源草作为天然产物提取原料提供理论支持
