We hypothesise that the E2 allele may protect against viral persistence via defective binding of HCV lipoviral particles to the cellular receptors involved in entry of these infectious particles.

我们认为E2等位子可能阻止病毒的持续复制和存在，其机理可能是在细胞受体与HCV脂病毒颗粒结合过程中，使脂病毒颗粒的结合功能出现障碍。

We hypothesise that the E2 allele may protect against iral persistence ia defectie binding of HC lipoiral particles to the cellular receptors inoled in entry of these infectious particles.

我们认为E2等位子可能阻止病毒的持续复制和存在，其机理可能是在细胞受体与HC脂病毒颗粒结合过程中，使脂病毒颗粒的结合功能出现障碍。

This experiment try to investigate the expressions of Epstein-Barr virus latent membrane protein 1(LMP-1),nuclear factor κ gene bindingand the apoptotic index in nasal NK/T cell lymphoma,and probe into the correlation of LMP-1 with NF-κB,AI,analyze their roles in the occurrence and development of nasal NK/T cell lymphomaMethods:From 1999 to 2004 ,26 cases of nasal NK/T cell lymphoma and 10 cases of benign lymph follicle hyperplasia were selected from Department of Pathology in Hospital of Shangdong province .

目的：EB病毒Epstein-Barr virus在鼻NK/T细胞淋巴瘤(nasal NK/T cell lymphoma)的瘤细胞的检出率较高，但其在淋巴瘤发生发展中的确切作用尚不清楚，本研究通过检测鼻腔NK/T细胞淋巴瘤中EB病毒感染潜伏膜蛋白(latent membrane protein-1，LMP-1)与细胞因子κB(nuclear factor κ gene binding，NF-κB)的表达及其细胞凋亡指数(apoptotic index，AI)，比较三者间相互关系，分析EB病毒在鼻NK/T细胞淋巴瘤发生发展中的致瘤机制。

At first ,the infection and proliferation of the virus in the midgut cells of silkworm were investgated by QC-PCR.

BmDNV-5是一株新分离到的家蚕浓核病病毒。为彻底解明该新发现病毒的生物学特性和背景，本文首先用QC-PCR法对该病毒在家蚕中肠细胞的感染增殖情况进行了调查。

Afterwards the recombinants were isolated and analyzed by amplifying PCR, using two primers specific for the HBV S genes.

对所获得的重组病毒经PCR分析、重组腺病毒DNA酶切分析证实重组病毒中含有目的基因。

By chicken embryo, minimum concentration of medicine of directly inactivated test、 treatment test and preventive test is 7.5mg/ml、 62.5mg/mland 31.25mg/ml;By CEF, minimum concentration of resiting NDVF_(48)E_8 and moderate virulence strain is 10mg/ml、 50mg/ml and 25mg/ml. However,the result of complex prescriptionpreventing and curing NDVF48Ej$ is not ideal.

在鸡胚上抗病毒试验中，对三株病毒起直接灭活、治疗和预防作用的最低药物浓度分别为7.5mg/ml、62.5mg/ml和31.25mg/ml；在鸡胚成纤维细胞上抗病毒试验中，对强强毒株和中等毒力株起直接灭活、治疗和预防作用不引起细胞病变的最低药物浓度分别为10mg/ml、50mg/ml和25mg/ml。

The viruses in question were retroviruses, which work by adding their genes to those of their host's cell nucleus.

在解决这项难题中使用的病毒是逆转录酶病毒，这些病毒把它们携带的基因添加到T细胞的细胞核中。

This packaging-and-replication system, and the genes involved, is comparable to a quite different group: the retroviruses, of which HIV is the best known.

这个装配－复制系统，与另外一种不同种的病毒－逆转录病毒（著名的HIV病毒就是其中的一种）是一致的。

In contrast to previously characterized human oncogenic retroviruses, the novel retrovirus they had discovered, now known as human immunodeficiency virus, did not induce uncontrolled cell growth.

相较于以往的特点人类致癌病毒，新病毒，他们发现了，现在被称为人类免疫缺陷病毒，并没有引起不受控制的细胞生长。

We now know that there is a whole group of these viruses, called retroviruses, which seem to operate in reverse, transferring information from RNA to DNA rather than the other way around as do cells.

我们现在知道有一整群称为&逆转录病毒&的病毒，这种病毒好象是逆向行事的，将遗传信息从RNA到DNA，不象细胞那样做。

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％。
