The sequences identities of SRY gene fragments of all animals of Artiodactyla available from GenBank were compared with the M.m.vaginalis SRY gene fragment. The phylogenetic tree was contructed and analyzed by UPGMA method and it was studied at the level of taxonomics and evolution.

将其序列与基因库中录入的所有偶蹄目动物的SRY基因序列进行同源性比较，用UPGMA法构建了其系统进化树，从分类和进化上对赤麂SRY基因进行分析

It indicated that:(1) The growth of rubber trees were increased in this intercropping pattern;(2) It was effective to decrease temperature of the rubber plantation in summer, increase the atmospherical moisture content and water content in soil;(3) It was also effective to improve the soil condition and increase its usable phosphor content.

结果表明：（1）间作唐鬼桑能促进中幼龄胶园的胶树生长；（2）可降低胶园的空气温度，提高系统内的空气相对湿度，增加胶园土壤含水量；（3）能改善土壤性状，增加土壤有效磷的含量。

Carotene and bixin inhibited the of MCF-7 human breast cancer cell significantly. The effects of carotenoids were pleiotropic.β-Carotene can activate PPARγ signal pathway and regulate expression of the downstream and relative genes, and impel cytochrome C liberation from mitochndria and increase the level of reactive oxygen species in cell.

胡萝卜素与胭脂树橙显著抑制乳腺癌MCF-7细胞的生长，β-胡萝卜素的抑制作用可能是多效性的，一是激活PPARγ信号系统，调节PPARγ下游基因及相关基因表达，另一个是促使线粒体中的细胞色素C释放，引起细胞内活性氧生成增加，导致细胞活力下降或坏死。

KDa. Phylogenetic tree analysis showed that the putative rice OsCAS had a high amino acid identity (99%) to maize β-caryophyllene synthase, whereas a low amino acid identity (51%) to those in other plants including Arabodopsis, Artemisia and cucumber.

系统进化树分析表明，水稻OsCAS基因编码蛋白的氨基酸序列与同为单子叶植物玉米的β-石竹烯合成酶氨基酸序列同源性达99%，而与其他植物的同源性仅51%。

Research is carried out in the following key areas: antibiotic resistance in bacteria, clostridial genetics, dendritic cells and their function, environmental microbiology and bioremediation, insect viruses and the biological control of insect pests, mycobacterial diseases of animals, microbial genomics, vaccine development delivery systems, viruses and viral vaccines etc.

With the strategy, it can construct fault trees highly automatically, compatibly and briefly for complex control systems.

本文给出的故障树建造方法，不仅能较好地解决复杂控制系统的建树的开放性和可移植性，而且自动化程度较高。

In general,this technique is used in the condition which is supposed that compone nts have dependent and definite distribution.However,in fact,no-binary state fau lt pattern often appear in variable systems.

但是，一般情况下的故障树分析都是事先假定元部件具有相互独立，确定分布的状态下使用，而在现实中，往往会出现非二态的系统失效模式。

Objective To study the antigenpresenting function of splenic dendritic cells in mice after hemorrhage plus closed fracture.Methods Splenic DCs were isolated 24h after hemorrhage plus closed fracture,then the ability to stimulate nonadherent splenocytes proliferation in the presence of conalbumin in vitro was detected,IL12 and IL10 levels in cell supernatants were measured by ELISA kits.

大量研究表明，创伤能引起机体免疫系统产生复杂的变化，树突状细胞(dendritic cells，DC)是体内功能最强的专职抗原递呈细胞(antigenpresenting cells，APC)，它可摄取和加工抗原，并分泌多种细胞因子，在激发T 细胞的免疫应答中起重要作用。

The distribution, resource volume, content of crude fat of Jatropha curcas were systematically investigated and studied in Yunnan province.

摘要对云南省麻疯树的分布区、资源量和粗脂肪含量开展系统调查研究。

The results of 16S rRNA sequence and phylogenetic analysis show that the strain is the closest relative to Desulfovibrio sp. with 96.0% sequence similarity.

基于16SrDNA序列同源性构建了系统发育树，结果表明此株菌是属于脱硫弧菌属的硫酸盐还原菌，与Desulfovibrio具有96.0%的序列相似性。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
