Objective to explore the possibility of using HBV as a gene delivery vector, and to test the anti-HBV effects by intracellular expression of dominant negative mutants of core protein.

目的探索H BV作为基因治疗载体的可能性及检验HBV点突变表达显性阴性突变体抗hbv的作用。

The positive and negative functions come along, but the positive function is always dominant.

选举的正反功能相伴而生，但正功能永远是主要的。

The results of dominant lethal test showed no statistical difference in the number of living, dead and resorbed fetuses between the exposed and the negative control groups.

显性致死实验结果表明各剂量组的受孕率、死胎和吸收胎数经统计学处理与阴性对照组无差异。

Pathological study was carried out on myelocytomatosis of diseased chickens of naturally infected and dominant type, concealed type of ELISA positive and negative control group respectively.

对禽骨髓细胞瘤病显性型病鸡、ELISA阳性的隐性型病鸡和阴性对照鸡进行了病理学研究。

Each enterprise only seeks its maximal self interest and this situation is undoubtedly negative to the dominant place of the whole supply chain enterprises.

各个企业也各自为政，只追求自身利益最大化，这无疑不利于整个供应链企业在竞争中取得主导优势地位。

Furthermore, hypothalamic dominant-negative Kir6.2 expression or the delivery of the KATP channel blocker glibenclamide abolished the glucose production-lowering effects of OAG.

此外，下丘脑显性负相Kir2的表达或使用KATP通道阻滞剂格列本脲能抵消oag的作用减少葡萄糖生成的作用。
