For constructing strong combined promoter to enhance the foreign gene expression in Fowlpox virus vector, four oligonucleotides were synthesized according to the essential structure of the vaccinia virus nature promoter P7.5 and were used for generating early and late promoters.

要提高外源基因在鸡痘病毒载体的表达量，必须使用强启动子来控制表达。为构建较强的启动子组合，根据痘苗病毒天然启动子P7.5的结构，人工合成4条寡核苷酸，形成一个早期启动子和一个晚期启动子，其首尾可相互连接。

Objective To prepare, purify and preliminarily identify the recombinant fowl pox virus expressing infectious laryngotracheitis virus glycoprotein D gene.

目的 制备传染性喉气管炎病毒gD基因重组禽痘病毒，并进行纯化及初步鉴定。

There are two primary forms of rabies: urban rabies, spread by nonimmunized domestic dogs and cats and rural rabies spread by the skunk, fox, raccoon, bat, and occasionally livestock.

他们是两个主要的类型：市内的病毒，扩散到没有免疫的家庭狗和猫，乡下的病毒扩散由臭鼬，狐狸，浣熊，蝙蝠，偶尔是家畜。

Objective: In order to investigate whether the recombinant adeno-associated virus -mediated foreign genes, LacZ/hVEGF, could pass the blood brain barrier by intra-carotid artery delivery or not and to investigate whether the foreign genes could be expressed in vivo in ischemic brain of the focal embolic stroke rats or not, a high titer and completely adenovirus free recombinant adeno-associated virus vector was constructed and studied.

目的：为了检测腺相关病毒载体携带的人类血管内皮因子基因能否通过血脑屏障及能否在脑组织中表达其基因产物，我们构建了一种新型、高滴度、无腺病毒污染的rAAV携带的报告基因和hVEGF基因分别经颈动脉对自体血栓局部脑卒中大鼠进行了研究。

This gene is known as env, and in free-living viruses the protein derived from it is responsible for locking on to a cell's surface to allow the virus to enter the cell.

这一基因命名为"env"，在游离的病毒体内，由其编码产生的蛋白质负责铆钉到细胞表面以使病毒得以进入细胞内。

Our studies showed that Chlorella viruses are ubiquitously distributed in fresh-water bodies in China.

以小球藻NC64A株系为寄主，从14个省市采集的数百个水样中普遍得到了病毒分离物，初步表明小球藻病毒在我国的分布是十分广泛的。

AIDS "may be more difficult to transmit than herpes," says Montefiore's Friedland."A number of pieces of information suggest that you need a large amount of virus." Studies of the sex partners of AIDS victims -- people who have had hundreds of sexual encounters with carriers of the virus -- show that 40% to 50% do not become infected with the virus.

蒙特菲里的弗雷兰德说：诸多信息表明只有大量的病毒才能使人染病，通过对由异性交合而感染艾滋病患者的研究显示40%至50%的人不会成为病毒的感染者，那些受感染的通常是与带有艾滋病毒的人有很多次的交合。

The wood of 侯 gold says, the " small three 阳s" just expresses the virus replication level lower, virus template still frowardly the 贮 exsits cell nucleus inside, once the term is in keeping with and then can enter to make duplicate afresh the appearance changes into the " big three 阳s".

侯金林说，"小三阳"只是表明病毒复制水平较低，病毒模板仍顽固地贮存在细胞核内，一旦条件适合就可以重新进入复制状态变为"大三阳"。

Colonno, taking advantage of these common receptors, devised a strategy for blocking the attachment of rhinoviruses to their appropriate receptors, Rather than fruitlessly searching for an antibody that would bind to all rhinoviruses.

例如，绝大多数鼻病毒在它们侵害人体细胞时，都会与细胞表面的相同分子相结合。Colonno利用这些普通受体，构想出一种策略，用于阻止鼻病毒附着与他们相应的受体。

The results show that the recombinant fowlpox virus is functional in expression of the H7 AIV HA.

该重组禽痘病毒的构建为AIV病毒活载体疫苗的研制奠定了基础。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
