有病毒的

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。

There is a risk of transmission of the virus between hypodermic users.

接受皮下注射者有相互传染病毒的可能。还是有一个不认识！

Transgenic tobacco plants were obtained through screening with kanamycin. The transgenic tobacco plants could delay TMV infection for about 25 days compared with non-transgenic tobacco plants. Pokeweed antiviral protein Ⅱ is expressed with high level in summer leaves. The expression of PAPⅡ is regulated by season. The total RNA was extracted from pokeweed (Phytolacca americana L.) leaves in summer using the method of TRIzol and used as template to amplify the PAPⅡ gene by RT-PCR and then the gene was cloned into E. coli expression vector and secreted expression pPIC9K vector. The two vectors with PAPⅡ gene were then transferred into E. coli strain BL21 (DE3)-plysS and Pachia pastoris GS115 strain respectively. The specific protein was produced induced by IPTG and methanol.

由于美洲商陆抗病毒蛋白Ⅱ是一个受季节调控表达的蛋白，本实验以美洲商陆夏季叶片为材料，通过对其总RNA的提取、反转录、并用PAPⅡ的特异引物进行PCR扩增，对PAPⅡ进行了基因克隆、序列分析，结果扩增出来的PAPⅡ基因与已经报道的序列同源性是99.9％，然后将该基因构建到原核、真核表达载体上，分别转化了大肠杆菌和毕赤酵母并对它们进行了诱导表达，在两个表达系统中均获得了有活性的PAPⅡ表达蛋白，体外生物测定表明表达的蛋白均具有抑制病毒的活性，PAPⅡ基因在酵母中还没有表达的报道，这为获得具活性PAPⅡ蛋白提供了一种简便可行的方法。

There is still going to be progression, and there unquestionably is still going to be a risk of HCC

只要有病毒血就会有进展，不可否认的，就会有HCC的危险。

Several unusual cases are briefly described, including verrucous herpes infection, condyloma-like molluscum contagiosum, and AIDS-associated pigmented erythroderma.

在本篇报告中，70%的人类免疫不全病毒感染患者有皮肤的症状，平均每位病患合并有 2.2 种皮肤疾病（爱滋病患者：3.2 种；非爱滋病患者：0.7 种，有统计学上的差异；p 0.001）。

It's not clear why Merck's compound failed so miserably, but researchers believe it may have to do with the vector , an inactivated cold virus, that was used to ferry the immunity-triggering HIV proteins into the body; some people may have developed enough natural tolerance to the common-cold virus that their immune system did not react to it, or to the viral payload piggybacked on it, at all.

现在还不清楚为什么默克公司的化合物如此失败，但研究人员相信，它可能是与载体有关，它们被用来转运免疫触发艾滋病毒的蛋白质进入体内，有些人可能对共同的感冒病毒发展了有足够的自然耐受以致他们的免疫系统对艾滋病毒没有反应，或对病毒的有效负载完全附带上。

Furthermore, the CIRMF's primatology centre is among the largest in Africa. It contains around 450 primates, including gorillas, mandrills and macaques, half of them housed in a forest enclosure."The natural hosts for SIV and STLV and many other viruses are African primates," says Bettina Salle, the veterinary surgeon who runs the primate centre."We have the ideal animal colonies and geographical location for research into the viruses in their natural hosts."

此外，这个中心的灵长类动物学研究中心是非洲最大的，共有大猩猩，大狒狒，短尾猿等灵长类动物450只约有一半的动物都被圈养在森林边缘在灵长类研究中心负责兽医工作的BS说：&SIV和STLV以及其他类似病毒的天然宿主是非洲灵长类动物对于我们来说，处于这些动物的聚集地，对于我们研究这些天然宿主身上的病毒真是太理想了&

ANALOGIES are often drawn between the fields of computer science and biology. The information-processing abilities of DNA are a form of natural molecular computing, and computer viruses leap from machine to machine in ways reminiscent of their disease-causing namesakes. At the International Solid-State Circuits Conference in San Francisco this week, a trio of mighty information-technology firms—Sony, Toshiba and IBM—pushed the analogy a little further. They unveiled a much anticipated new computer chip, four years in the making, the very name of which is a biological metaphor: the Cell.

人们经常把计算机科学和生物学进行类比，DNA的信息处理能力是一种自然分子的计算形式，而计算机病毒则让人想起致病性生物病毒，从一台机子感染另一台机子，而这个星期，信息技术的三巨头——索尼、东芝和IBM在旧金山召开的国际晶体管集成电路会议上，把两者间的这种类比作了进一步的推进，他们披露了一种已经研制了四年的、非常有希望的新型计算机芯片，这种芯片的名字来自生物学：细胞。

Detecting each marker and cmparison the location of sequential tissuesection could determine the area loceation relationship of the markers, but it is difficulte to determine their correlation intra-cells exactly. No report of detecting virus genome and antigenes on a one section with triple staning techniques exists in the lit erature. in this report. by combining immunohistochemistry and in situ hybridization (with dioxigenin labelled HBV DNA probe), a triple staining technigce was established. With this technic, on one formalin-fixed and paraffin embeded section, HBV DNA, HBsAg and HBcAg were determinated one after the other.

各个细胞内病毒的复制和表达水平以及与肝细胞病变的关系，是乙型肝炎发病机理研究的一个重要方面：目前常用的在系列切片上对各标志物分别检测，比较观察的方法，一般只能大致了解各待检物在某一区域的定位关系，很难准确地了解它们在同一细胞内的关系：国内外尚未见有在同一张切片上三重标记染色检测病毒核酸及其多种抗原的报道：本文结合免疫组织化学ABC法及地高辛配基标记HBV DNA探针原位杂交，建立三重标记染色技术：在一张福尔马林固定石蜡包埋肝组织切片上先后检测，同时显示HBV DNA、HBcAg和HBsAg。
