1长江中华鲟超声波遥测技术显示文摘利用美国Sonotronics公司的超声波发射器、接收仪和水下听筒装配的一套超声波遥测定位系统,在长江宜昌江段对中华鲟进行遥测试验,方法可靠,在葛州坝下江段其探测半径约达1500米。借助特制快艇和GPS,采用三角定位法,可较准确地定位中华鲟行踪。超声波发射器的特定声波编码,可将不同标志个体区别开。本试验1995和1996年标志了15尾即将参加自然繁殖的中华鲟。其中1996年标志10尾,全部进行了定位追踪,记录了各尾鲟在产前、产卵和产后的行踪,各尾鱼持续定位6~48天,平均19.8天,总定位次数达573次。该方法也适用于其它的江河和其它鱼类和水生动物迁移规律、产卵场定位和产卵条件等研究。危起伟 杨德国 柯福恩 BOYD KYNARD MICAH KIEFFER 1998水产学报1998,22,3:29

3钼掺杂LaVO_4上丙烷氧化脱氢显示文摘研究了钼掺杂LaVO4催化剂的丙烷氧化脱氢催化性能.加入钼对丙烷氧化脱氢反应有很好的助催化作用.当丙烷转化率恒定在10%和20%时,丙烯选择性在LaMo0.1V0.9O4.05上分别达到了56%和43%,而在LaVO4上仅为36%和22%,这归结为钼掺杂催化剂上有利于丙烯生成的可活动氧物种的增加和催化剂氧化还原性的改变.照日格图 李文钊 于春英 徐恒泳 Roger Kieffer 2002物理化学学报2002,18,1:7
4Recent advances in the understanding of the molecular mechanisms regulating platelet integrin αIIbβ3 activation显示文摘Integrins are allosteric cell adhesion receptors that cycle from a low to a high affinity ligand binding state,a complex process of receptor activation that is of particular importance in blood cells such as platelets or leukocytes.Here we highlight recent progress in the understanding of the molecular pathways that regulate integrin activation in platelets and leukocytes,with a special focus on the structural changes in platelet integrinαIIbβ3 brought about by key intracellular proteins,namely talin and kindlins,that are of crucial importance in the regulation of integrin function.Evidence that the small GTPase Rap1 and its guanine exchange factor CalDAG-GEF1,together with RIAM,a Rap1GTP adaptor protein,promote the interaction of talin with the integrinβsubunit,has greatly contributed to fill the gap in our understanding of the signaling pathway from G-coupled agonist receptors and their phospholipase C-dependant second messengers,to integrin activation.Studies of patients with the rare blood cell disorder LAD-III have contributed to the identification of kindlins as new co-regulators of the talin-dependent integrin activation process in platelets and leukocytes,underlining the relevance for the in-depth investigation of patients with rare genetic blood cell disorders.Lanlan Tao Yue Zhang Xiaodong Xi Nelly Kieffer 2010Protein & Cell2010,1,7:3
