Two dinuclear metallocenes with biphenyl bridge were synthesized. and their catalytic properties for the polymerization of ethylene were investigated.

3对于具有超高活性的混合双茂化合物，我们用联苯桥连合成了其类似的双核茂金属化合物。

The cloning of bar gene is important to plant transgenic engineering, gene expression and studying physiology.In the experiment, the full code sequence of bar gene was cloned by PCR from transgenic herbicide resistant Bobwhite wheat and checked. It was expressed in E.coli and its protein was determined.

本实验从抗除草剂转基因Bobwhite小麦中，利用PCR克隆的方法扩增出bar基因全长，并在原核表达系统中表达，鉴定表达蛋白的活性，将能够正确编码PPT乙酰转移酶的bar基因片段，经过适当的修饰构建入真核表达载体。

During capacitation Ca〓 was present on the outer surface of IAM and in the released acrosomal contents.

精子获能前内存Ca〓主要分布于顶体外膜内侧和顶体内膜与核膜之间，并在获能和顶体反应过程被动员利用；顶体反应精子Ca〓分散存在于释放的顶体内容物中和结合于顶体内膜外侧，可能与顶体酶的活性有关；（9）。

Specifically, we found that activity in the caudate nucleus, a critical part of circuits that link the prefrontal cortex of the brain, is reduced in boys with autism.

值得注意的是，我们发现尾状核的活性在自我封闭症的男孩中降低，这是连接大脑额前叶通路的关键部分。

The recombinant eukaryotic expression vector pcDNA3.1-Myc-His B/tPA can stable express tPAcDNA in transfected hUVEC cell strains and can secret compt tPA protein. Experiment III The Effects of Transfected tPA Gene on Vascular Smooth Muscle Cells Proliferation and Migration in VitroObjective To investigate the effects of transfected tPA gene on vascular smooth muscle cell proliferation and migration in vitro and to provide a basis for further study on preventing vein graft restenosis.

结论构建的pcDNA3.1-Myc-HisB/tPA基因新型真核表达载体，能在HUVEC中表达，其表达具有高拷贝、稳定性好的特点，获得的表达蛋白活性较高，提示本载体和稳定表达tPA基因的人脐静脉内皮株能够作为基因治疗工具用于哺乳动物的实验研究。

Deoxyadenosine is the first nucleoside antibiotic separated from epiphyte, it has many pharmacological activities.

虫草素第一个从真菌中分离出来的核苷类抗菌素，它具有多种药理活性作用。

The results showed YYSXF could raise survival rate of the mice after irradition, increase activity of superoxide dismutose and reduce quantity of the lipid peroxide in liver and red blood cell, extenuate micronucleus formating in V79 4 cell, promote unscheduled DNA synthesis and induce production of interleukin 2 in spleen cells and protect bone marrow cells in mice.

结果表明养阴生血饮能提高致死剂量照射动物30d和小剂量多次照射60d及荷瘤小鼠1次照射后20d的存活率；能增加超氧化物岐化酶的活性；降低过氧化脂质的水平；减少细胞的微核形成；促进脾细胞DNA修复；诱导脾细胞产生白细胞介素－2；保护骨髓造血功能

In our experiments, when the opacity of lens exceed Ⅳ degrees, the treatment effect of medicine was not obviously. Analyzing the examined results of AR, SOD and GSH-px in rat lens cortex and nuclear shows that Zhangming drops can inhibit the activity of AR obviously and prevent the translation of galactose to galactose alcohol. So it can prevent the deposit of galactose in the fibrocyte of lens and the increase of lens's osmosis, then prevent the hydration of lens.

通过对大鼠半乳糖性白内障晶体皮质和核内醛糖还原酶、超氧化物歧化酶和谷胱苷肽过氧化物酶的检测结果分析表明，障明滴眼液能明显抑制AR的活性，防止半乳糖向半乳糖醇的转化，从而防止半乳糖在晶体纤维细胞内的堆积，阻止其渗透性的增高，防止晶体的水化。

METHODS: After AIF△1-120 gene was successfully cloned, the shorter truncated human AIF gene (AIF△1-400) was constructed by deleting the Nterminal mitochondrial localization sequence, the coding sequence of flavine adenine dinucleotide binding domain and nicotinamide adenine dinucleotide binding domain of AIF protein.The truncated human AIF gene (AIF△1-400) was inserted into the pIRES2EGFP and pcDNA3 eukaryotic expression vectors, and the coexpression vectors were then transfected into HeLa cells with LipofectAMINE.

在AIF△1-120基因克隆成功的基础上进一步改造，构建截去AIF基因线粒体定位信号，FAD结合结构域和NADH结合结构域（1-400位氨基酸）编码序列的AIF△1-400基因，将其克隆入pcDNA3和pIRES2EGFP真核表达载体，用脂质体法转染HeLa细胞，通过荧光显微镜观察，MTT检测等方法检测该基因在转染细胞中的表达及其对肿瘤细胞的促凋亡活性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
