1蒙古黄芪中核糖核酸酶活性蛋白AmPR-10的纯化和性质研究显示文摘目的采用全自动智能蛋白纯化系统AKTA Avant25建立蒙古黄芪病程相关蛋白(Astragalus membranaceus pathogenesis-related protein-10,AmPR-10)的稳定快速分离纯化方法,并分析其理化性质和生物学活性。方法蒙古黄芪经Tris-HCl缓冲液浸提后阴离子交换色谱捕获目标蛋白,疏水色谱精细分离,凝胶滤过色谱进一步精细分离得到AmPR-10。采用MALDI-TOF/TOF质谱法测定相对分子质量,质谱检测后MS/MS Ion Search检索鉴定蛋白,高碘酸-Schiff法判断是否为糖蛋白,琼脂糖凝胶电泳分析核糖核酸酶活性及不同影响因素对核糖核酸酶活性的影响。结果蒙古黄芪粗提液经Q Sepharose Fast Flow、Butyl Sepharose High Performance和SuperdexTM 75 10/300 GL 3步纯化后可得到电泳纯AmPR-10;质谱测定其相对分子质量为16 801;蛋白鉴定其属于PR-10蛋白家族;糖蛋白染色显示其不含糖链。AmPR-10具有显著的核糖核酸酶活性,且其活性对Na Cl浓度、pH值和金属离子的敏感度低,仅0.5 mol/L NaCl、pH 9.0、Mg^(2+)和Co^(2+)对其有微弱的抑制作用,EDTA对AmPR-10核糖核酸酶活性无影响。结论离子交换色谱-疏水色谱-凝胶过滤色谱3步法纯化AmPR-10快速稳定,可应用于其他中药蛋白质的分离纯化。AmPR-10可能在蒙古黄芪抵御RNA病毒侵染中发挥重要作用。任晋宏 王永辉 薛慧清 刘晔 Divid Adelson 陈薛静 李敏 高丽 2017中草药2017,48,19:7
2优化下肢慢性创面愈合中的技术应用:共识文件(译文)显示文摘目的:慢性创面处理中技术创新随处可见。尽管多种技术得到了广泛的应用,但并不总是能够确保创面愈合的结局。这份共识文件为创面标准化处理的相关诊疗技术应用提供了循证研究依据。Raj Mani Divid J.Margolis Vijay Shukla Sadanori Akita Miltos Lazarides Alberto Piaggesi Vincent Falanga Luc Teot 谢挺 付小兵 Marco Romanelli Chris Attinger 韩春茂 陆树良 Sylvie Meaume 许樟荣 Vijay Viswanathan 孙晓芳 肖娴 2017感染.炎症.修复2017,18,2:7
3蒙古黄芪病程相关蛋白AmPR-10纯化及生物学功能研究显示文摘蒙古黄芪病程相关蛋白(Astragalus membranaceus pathogenesis-related protein 10,AmPR-10)在蒙古黄芪遭遇环境压力和病原体侵袭时大量表达,该研究旨在探讨AmPR-10的生物学功能。蒙古黄芪干燥根经机械粉碎后缓冲液浸提得到蒙古黄芪总蛋白粗提液,总蛋白粗提液经阴离子交换色谱和凝胶过滤色谱纯化后得到电泳纯AmPR-10。以不同RNA为底物,通过检测260 nm吸光度分析核酸酶活性,结果显示AmPR-10对Yeast tRNA,Yeast RNA,Poly(A)和Poly(C)均表现核酸酶活性,且其最佳反应温度为50℃,最佳反应pH为78,EDTA对其活性无影响,Mg^2+对其活性具有激活作用,Co^2+,Ca^2+和Zn^2+对其活性具有抑制作。AmPR-10与已知核酸酶无序列同源性,可能是一种新的核酸酶。采用Lineweaver-Burk双倒数作图法分析AmPR-10木瓜蛋白酶抑制活性,结果显示AmPR-10是木瓜蛋白酶的非竞争性抑制剂。AmPR-10可能通过抑制半胱氨酸酶活性在蒙古黄芪对抗环境压力和抵御病原体侵袭的过程中发挥重要作用。任晋宏 薛慧清 刘晔 魏砚明 Divid Adelson 陈薛静 周静红 于建东 2018中国中药杂志2018,43,18:6
4Communication contention in APN list scheduling algorithm显示文摘Task scheduling is an essential aspect of parallel process system. This NP-hard problem assumes fully connected homogeneous processors and ignores contention on the communication links. However, as arbitrary processor network (APN), communication contention has a strong influence on the execution time of a parallel application. This paper investigates the incorporation of contention awareness into task scheduling. The innovation is the idea of dynamically scheduling edges to links, for which we use the earliest finish communication time search algorithm based on shortest-path search method. The other novel idea proposed in this paper is scheduling priority based on recursive rank computation on heterogeneous arbitrary processor network. In the end, to reduce time complexity of algorithm, a parallel algorithm is proposed and speedup O(PPE) is achieved. The comparison study, based on both randomly generated graphs and the graphs of some real applications, shows that our scheduling algorithm significantly surpasses classic and static communication contention awareness algorithm, especially for high data transmission rate parallel application.TANG XiaoYong LI KenLi PADUA Divid 2009Science in China(Series F)2009,52,1:5
5新疆二种白蛉分类地位的校订显示文摘研究了存放在英国伦敦自然历史博物馆 (BMNH)的中国新疆和哈萨克斯坦、吉尔吉斯坦等地的有关白蛉标本 ,发现丁绍铎和何凯增 (196 2 )报道的“硕大白蛉”(P.major Annandale,1910 sensu Ting & Ho,196 2 )及杨赣源、熊光华(196 5 )的“硕大白蛉吴氏亚种”(P. major wui Yang & Xiong,196 5 )两者皆是斯氏白蛉 (P. smirnovi Perfiliew,194 1)的异名。丁、何的“微小白蛉新疆变种”(P.minutus var.sinkiangensis Ting & Ho,196 2 )应属于司蛉属 (Genus SergentomyiaFranca & Parrot,192 0 )司蛉亚属触角组 (antennata- group Theodor,195 8) ,兹重新命名为新疆司蛉 Sergentomyia(Sergen-tomyia) sinkiangensis (Ting & Ho,196 2 ) nom. nov.,并确定了选模。冷延家 Richard P.LANE Divid J.LEWIS 2002中国寄生虫病防治杂志2002,15,5:4
