安曼市政府作为&达拉特国王阿卜杜拉二世&的业主，敲定了两个获胜方案。

He mechanism underlined this effect may be linked to the demethylation of RIZ1 promoter.

的RIZ1 基因表达可能同RIZ1 基因启动子去甲基化作用有关。

Inhibition of this process precludes demethylation of the pS2 gene promoter and its subsequent transcriptional activation.

这种抑制作用不影响pS2基因启动子序列的甲基化和其后随序列的活性。

On the other hand, a method for the synthesis of-vinyl chalcogenides by the coupling of vinyl bromides with thiols or diphenyl diselenide using copper salts as catalysts in ionic liquids based on amino acids also has been described. The ionic liquids play multiple roles in the reaction: they act as solvent, base, and excellent promoter for the copper-catalyzed coupling reactions.

在新型的氨基酸负离子的离子液体中，开发了一个亚铜盐催化的Z-型溴代烯烃与硫族元素的交叉偶联反应，为立体选择性的制备Z-型烯基硫醚或烯基硒醚类化合物提供了一个新的方法；在此反应体系中，离子液体不仅起到了反应溶剂的作用，而且还起到了金属催化剂的配体和中和反应副产物的碱的作用。

The research work involving the expression manner of doxA gene in S. lividans TK24 with plasmid pYG57 implied that the promoter PermE may control its expression constitutively, the time for maximum expression emerged from 48 to 60 h after inoculation and cultivation and the expression level was kept relatively stable, furthermore, the recombinant hydroxylase existed mostly in mycelium cell but little in broth.

而对Tm4（pYG57）菌株中doxA基因表达方式的研究表明， dd基因在 PermE启动子控制下可能是一种组成型控制表达，其表达量在接种后培养到 48－60 h左右最高并且维持相对稳定，并且表达的柔红霉素 Cl4羟化酶主要存在于菌丝体细胞内，很少分泌到细胞外。

The SDS-PAGE electrophoresis indicated that all engineered strains containing different expression plasmid could apparently express a 45 kD band specific for daunorubicin C-14 hydroxylase. The expression level of doxA gene was much higher when the doxA gene was under the control of promoter PermE. However, it was found that fd terminator had few effect on the expression of doxA gene.

SDS-PAGE蛋白电泳实验证明，上述五个菌株都能够表达大小约45 kD的柔红霉素C-14羟化酶蛋白，并发现以在PermE启动子控制下的doxA基因表达量相对较高，而终止子对＠中英文摘要 dd基因表达似乎没有影响。

Five plasmids for the expression of doxA gene, which were designated as pYG57, pYG502, pYG503, pYG505 and pYG506 were constructed so that the cloned doxA gene were under the control of either promoter of melanin gene or erythromycin resistant gene or their tandem promoters, and a fd terminator downstream.

构建了五个doxA基因链霉菌表达质粒pYG57、pYG502、pYG503、pYG505和pYG506，使得doxA基因在上游的Pmel启动子、红霉素抗性基因启动子或者两者的串联启动子，以及下游的fd终止子控制之下。

Methods The promoter of hTERT and Cox-2 was subcloned from human genomic DNA, then ligated to shuttle vector pd306 which contains the Ela and Elb gene of adenovirus to control the expression of Ela and Elb,respectively.

将hTERT和Cox-2启动子从人类白细胞基因组中亚克隆出来，并将启动子分别插入到腺病毒穿梭载体pd306上的E1A和E1B基因前，使hTERT和Cox-2启动子分别调控腺病毒必须基因E1A和E1B的表达，再将构建后的pd306和腺病毒的骨架质粒BHGE3在Ad293细胞内进行同源重组，并用重组后的病毒感染Hela细胞检测病毒对肿瘤细胞的杀伤力。

To define further the fragments regulating gene expression, the Lcn5 promoter was examined in transgenic mice and immortalized epididymal cell lines.

经过一系列的缺失试验后，发现在转基因小鼠中Lcn5基因1.8 kb长的启动子片断对于基因的组织特异性和区域特异性表达是必需的。

Some environmental factors could confer a predisposition to depression by affecting the genome epigenetically — for example, increased maternal care in rodents causes an epigenetic change in the promoter region of the glucocorticoid-receptor gene.

一些环境因子可能赠予抑郁易感性，累及后生染色体—例如，在啮齿动物的糖皮质激素受体基因启动子区增加母体的忧虑可引起后生变化。

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。
