本实验在以往罗氏沼虾(Macrobrachiumrosenbergii)苗种肌肉白浊病病毒致病性的基础上对病毒特性进行深入研究。病虾除菌过滤液以1:50和1:250浸泡感染可复制出典型的症状,病毒对氯仿抵抗;用PEG法浓缩病毒后,35000r/min超速离心部分纯化病毒,在电镜下可观察到大量直径24nm的球形病毒颗粒,无囊膜,此外还观察到大小为14nm的病毒粒子;采用Trizol试剂对病毒进行了核酸提取,电泳结果发现有4条核酸条带,分别为3.0kb、1.3kb、0.8kb、0.75kb,对RNA核酸酶、S1核酸酶敏感,对DNA酶抵抗,为单链RNA病毒。用罗氏沼虾诺达病毒核酸探针进行分子杂交,探针可与提纯核酸及病虾样品匀浆液反应,Southern杂交表明3.0kb、1.3kb条带分别属于诺达病毒的RNA1和RNA2。对不同的发病样品进行了核酸电泳,4个典型症状的样品均存在诺达病毒条带,2个样品还存在小病毒核酸。上述结果表明,诺达病毒是引起罗氏沼虾苗种肌肉白浊病的主要病原。14nm小病毒与罗氏沼虾肌肉白浊病中的关系有待进一步的研究。

东海DGKS9602钻孔位于北纬28-°12″,东经127-°037″,水深988米,岩芯总长9.31m,是1996年5月中法科学家合作利用法国L’ATALANTE号海洋调查船在东海陆架获取的17个岩芯中的一个。根据89个孢粉样品分析反映的植物冷暖种属及草本木本含量的相对变化,以及利用东亚现代孢粉数据库和类比法定量重建了一系列定量的古气候值,探讨了该钻孔所记录古气候演变,由于钻孔位置位于东海大陆架,沉积物主要来源于长江流域,特别是中下游地区,因此钻孔所揭示的环境演变主要与长江流域地区相关。钻孔的年代框架主要由氧同位素d18O曲线对比和AMS14C测年来获得。本研究的主要结论如下:

Understanding the molecular mechanism of the protein assembly still remains a challenge in the case of many biological systems. In this frame, the mechanism which drives RodA hydrophobins to self-assemble onto the surface of the conidia of the human fungal pathogen Aspergillus fumigatus into highly ordered nanorods known as rodlets, is still unresolved. Here, AFM investigations were combined with Monte Carlo simulations to elucidate how these small amphiphilic proteins self-assemble into tightly packed rodlets and how they are further organized in nanodomains. It becomes that the assembly of RodA hydrophobins into rodlets and their parallel alignment within nanodomains result from their anisotropic properties. Monte Carlo simulations allowed us to confirm that anisotropic interactions between macromolecules are sufficient to drive them to assembly into rodlets prior to nanodomains formation. Better knowledge of the mechanism of hydrophobins assembly into rodlets offers new prospects for the development of novel strategies leading to inhibition of rodlet formation, which should allow more rapid detection of the conidia by the immune system.

应用地高辛标记的对虾白斑杆状病毒 (whitespotsyndromebaculovirus,WSSV)核酸探针 ,与人工感染后不同时间采集的对虾组织样品进行原位杂交 ,以动态研究病毒从侵染至对虾发病死亡的过程。将典型感染WSSV的病虾组织投喂健康对虾 ,结果显示 :WSSV首先通过侵染消化道上皮进入虾体内增殖 ,此后随着细胞裂解、病毒粒子释放 ,游离的病毒粒子伴随血淋巴循环进而侵染其它靶组织 ,直至对虾发病死亡。
