The current study was conduct to analyze the distribution characters of single nucleotide polymorphisms 1166A/C of AT1R gene, and to investigate the association between AT1R gene SNP and essential hypertension and hypertensive left ventricular remodeling in Chinese Souther...

本课题旨在研究AT1R基因1166A/C单核苷酸多态性在中国南方汉族人群的分布特征及其与高血压病及其左室重构的关联关系，以期从分子水平探讨高血压发病和预后的机制及特点，为高血压病及其重要靶器官损伤遗传易感基因的识别和高血压病的防治提供科学依据。

What helped him was that under the command of Minghui Net, more than 100 Falun Gong royalists suddenly gathered in Tian'anmen Square and made troubles in order to appeal for the world when UN Human Right Committee was about to take a vote on a U.S.

与之配合的是在"明慧网"的指挥下，4月13日，联合国人权委员会即将表决美国提出的所谓谴责中国的议案之际，100多名"法轮功"顽固分子突然在北京天安门广场聚集滋事，企图引起全世界的瞩目，与美国反华势力遥相呼应。

"Since DM is a multisystemic disease, it is difficult in humans to uncouple the specific molecular abnormalities which lead to cardiac disease from pathological events in other tissues. The fact that this inducible model develops many of the characteristic features of DM heart disease is remarkable and validates the use of this approach." He added, however, that therapeutic approaches developed in animal models might turn out to be ineffective during human clinical trials.

因为DM是一种多系统性疾病，在人类难以从其他组织的病理解开会导致心脏疾病的特定分子异常，事实上，是这个归纳模式发展出许多DM心脏疾病的特徵，这些是重要且对研究有用的，不过，动物模式发展的治疗方式，可能在转成人体临床试验之后变得无效。

The experimental results show that Mn2O3 was main active species and addition of Zr further activated methane molecules to improve methane conversion; C2 selectivity was improved by adding W and P, and suppressed deep oxidation property of SiO2; W–O in catalyst surface was not active species.

通过选取五组该催化剂对其进行XRD、XPS、FT-IR以及SEM表征，表明Mn2O3和Na2Zr(PO4)2是多组分甲烷氧化偶联催化剂的活性组分，且Mn2O3起主要作用，Zr的加入进一步活化了甲烷分子，提高了甲烷的转化率，W和P的加入改善了C2烃的选择性，抑制了SiO2的深度氧化特性；W–O物种不是催化活性物种。

Well-meant actions often have unintended effects: fighting can create more insurgents than it kills; foreigners are blamed for attacks that hurt Afghan civilians; and schemes to win people over can deepen antagonism.

善意的行动常常达不到应有的效果：打仗只会致使更多的叛乱分子站起来；外国驻军却因伤害阿富汗平民的事件而备受谴责；争取获得民众的计划也只会加深敌对情绪。

Started from D-tyrosine, we obtained the tetramic acid 96 using Jouin reaction. The assembly of the second fragment 109 was stared from 1,4-butandiol,using asymmetric alkylation reaction developed by Oppolzer as a key step. Coupling of the tetramic acid 96 with 109 provided the key intermediate 110 according to Yoshii\'s procedure. After remove protective group and Sharpless epoxidation, we obtained the key intermediate 113. Its macrocyclization to form the final product is in progress.

本论文的第二章主要对Macrocidin A开展了合成工作，我们从D构型的酪氨酸出发，经过官能团转换；利用Jouin反应生成Tetramic acid 96，另外一个片断从1，4-丁二醇开始经过多步反应生成碘化物104，利用Oppolzer发展的手性樟脑磺酰胺为辅基参与的不对称烷基化反应，引入手性甲基，生成关键中间体109，接着通过Yoshii发展的方法连接96和109生成110，经过Sharpless不对称环氧化反应建立环氧化合物，然后脱去保护基得到关环前体113，分子内的Mitsunobu反应进行关大环反应正在进行之中。

It can grow all right in high salt Since twenty century , molecular biology and bio-technology have a large development , agriculture and physic have been speedily development too ,especially after the plan of human genome was successfully implemented ,more people engaged in bio-technology industry .but the area of the bio-technology study was very extensive , Ocean Rhodotorulas have been studied by people at beginning, on the end of 1980s , Ocean Rhodotorulas separation from sea and Japan was the first succeed in cultivation by zymolysis , the Ocean Rhodotorula of cultivation was used for a good nutrimental to feed for fish and shrimp.

二十世纪以来，分子生物学与生物技术得到了迅猛发展，在农业和医药业都得到了飞速发展，尤其是人类基因组计划的成功实施，使人们更多的从事着生物技术行业，但是生物技术研究的范围很广，所以对于海洋红酵母的研究还处于刚刚起步阶段，上世纪80年代日本最早分离到海洋红酵母，然后发酵培养，用做鱼虾的营养饲料。

Cardiolipin is a unique Phospholipid with dimeric structure, carrying four acyl groups and two negative charges.

心磷脂是脂类中独一无二的带有负二价头部基团及多达四条尾链的磷脂分子，是线粒体内膜的主要成分，作为与功能相关的膜结构转变的主要参与者，近几十年来深受研究者的关注。

Taking Shewanella and Geobacter as examples, this paper reviewed three kinds of possible mechanisms of microbial enzyme-catalyzed dissimilatory Fe reduction and its molecular regulation, i.e., direct contact between microbial cell and Fe oxides, siderrophores, and electron shuttling compounds. Many membrane-bound cytochrome proteins are involved in the dissimilatory Fe reduction, forming a complicated regulation network.

以希瓦氏菌和地杆菌为例，本文综述了3种异化Fe还原的酶促反应机制及其分子调控机理：异化Fe还原菌与Fe氧化物直接接触机制、电子穿梭体的作用机制、铁载体作用机制，多种膜蛋白特别是多血红素的细胞色素蛋白参与微生物的异化Fe还原过程，并形成复杂的调控网络。
