病毒

The drug had no influence on inactivating virus and release from the cell, however, it had influence on virus absorption.

药物对病毒没有直接灭活作用，对病毒的释放也没有影响，主要影响了病毒的吸附。

That is because new viral diseases generally happen when a virus mutates in a way that allows it to jump species, and then continues to evolve to exploit its new host.

那是因为一种新的病毒性疾病的形成是由于病毒突变引起的，这种病毒的宿主发生物种间的跨越，而该病毒能随之进化以适应新的宿主。

Viruses do 'escape' from laboratories, even high security facilities. The H1N1 influenza lineage that circulated in the human population for four decades after the 1918 Spanish influenza epidemic, disappeared during the 1957 Asian influenza pandemic, was absent for two decades, but then reappeared in 1977. Gene sequences of the 1977 isolate and others collected in the 1950s were almost identical, indicating that the virus had not replicated and evolved in the interim, and had probably been held in a laboratory freezer between 1950 and 1977 and 'escaped' during passaging.

病毒确实从实验室中'逃跑'，即使有高度保护设施。H1N1家族流感病毒，在人类传播了40年自1918年西班牙流感疫情之后，在1957年亚洲流感大流行后失踪，消失了20年，但随后在1977年重新出现。1977年分离基因序列和在20世纪50年代收集的基因序列几乎相同，这表明病毒并没有复制和演变在中间期，并可能在1950年至1977年保存在实验室冷冻器，又在中间期内&逃脱&出来。

But potentiating effect on IFN-induced growth inhibition was fewer noticeable in 1.4 μg/ml of synthetic peptide.

体外抗病毒结果显示，干扰素在亚保护剂量时(20～70 pg/ml)时，合成肽能提高IFN-α作用细胞后的抗病毒活性，并且合成肽WLDPRH在1.4 μg/ml时， IFN-α抗病毒保护率从40%提高到86%，为最高保护率的最低剂量，但合成肽为1.4 μg/ml， IFN浓度为5～55 ng/ml时，对IFN-α诱导的抗增殖作用不明显。

Up to 50 million people worldwide died in the 1918 Spanish flu pandemic. In 2005, a team led by the US Centers for Disease Control and Prevention reanimated the virus from a 1918 flu victim. Now the virus is out there, in a lab fridge.

1918年西班牙流感病毒大肆流行，世界范围内不下5000万人命丧黄泉。2005年，一支由美国疾病控防中心牵头的研究小组，复活了1918年流感牺牲者感染的病毒，这些病毒目前就存放在一个实验室的冰箱中。

Our laboratory centers on two reemerging flaviviruses in Taiwan, dengue virus and Japanese encephalitis virus.

本实验室的研究工作以两个在台湾相当重要的黄质病毒：日本脑炎病毒以及登革病毒为主。

The purpose of this article is to review the major features of the zoonotic arenaviruses from the angles of their taxonomy and classification, epidemiology and ecology, mode of transmission, clinical signs, prevention and control, etc. Which are important for the reason that viruses causing severe disease in humans are reemerging somewhere the world.

沙粒病毒是一科由啮齿动物为宿主、能够以多种方式感染并引起人类不同程度病死率疾病的RNA病毒，近来在非洲及南美出现局部流行，本文从病原学、生态学、流行病学、临床病理及预防控制等方面回顾了该病毒的研究进展。

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%.
