疫苗

In a paper published this week in Nature, they recast the mathematics of vaccination with this in mind.

本周刊登于《自然》杂志的一篇论文称，他们基于上述想法，重新提出了计算疫苗接种数的数学方法。

E1 envelope protein is one of the structural protein of HCV,having important receptor binding site and epitope,it play important role in the process of viral infection and immunity.

丙型肝炎是由丙型肝炎病毒(Hepatitis C virus， HCV )感染而引起的严重威胁人类健康的传染病，还没有研制成功有效的疫苗。

Results Several amino acid substitutions located in antigenic sites or receptor binding sites were found more in the isolates than the current vaccine virus or the isolates from previous year. Amino acid substitution was found in 3, 140, 142, 144, 145, 158, 159, 189, 192, 193, 198, 204, 225, 226 and 227 positions in the isolates during 2003-2008, more amino acid substitutions took place in antigenic determinant A, B and receptor binding site.

结果 每个流行期分离的毒株都较当年的疫苗株或前一年的毒株出现了位于不同抗原决定簇或者受体结合位点的氨基酸替换。2003-2008年不同流行期分离株在3，140、142、144、145、158、159、189、192、193、198、204，225、226和227位点氨基酸发生了变化，多数的改变发生在抗原决定簇A、B及RBS。

Hepatitis C,caused by hepatitis C virus,is an important infectious disease threatening human health,and at present,there are no vaccines available for preventing HCV infection.The E1 envelope protein is one of the structural protein of HCV,having important receptor binding site and epitope,it play important role in the process of viral infection and immunity.

丙型肝炎是由丙型肝炎病毒(Hepatitis C virus， HCV )感染而引起的严重威胁人类健康的传染病，目还没有研制成功有效的疫苗 HCV-E1包膜糖蛋白是HCV的结构蛋白之，具有重要的受体结合位点和抗原表位，在病毒感染和宿主免疫过程中起着十分重要的作用。

Therefore,pTL-8/AMA-l combined with pUHS6-l is a good regulable DNA vaccine candidate against Plasmodium falciparum. The constructionof this system lays the foundation for future research to explore the mechanism of DNA immunizaiton and regulate the antigen expression to reduce side effects of DNA vaccines.

该系统的建立将对进一步深入研究DNA疫苗的免疫机制和调控基因表达、减少不良免疫反应以及进行可精确调控的基因治疗打下一定的基础

The vaccines would reduce fertility in Muslim girls, they said, before ultimately relenting.

他们说疫苗会使穆斯林女孩身体素质下降，最终事件得以缓和。

The goal is to keep the disease in remission for a longer time.

这种疫苗的目的是使疾病更长时间地处于缓解期。

A vaccine as soon as possible to replant it, 30 micrograms of high-dose.

尽快去补种一次疫苗吧，30微克大剂量的。

It would requite a rather strong vaccine to be of much value at this age.

此时需要疫苗的毒力相对强些。

Tianjin is also the first country to achieve a government-funded, free for children aged 2-13 resow hepatitis B vaccine, and have achieved remarkable results.

天津市还在全国第一个实现了由政府出资，免费为2至13岁儿童补种乙肝疫苗，并取得了明显效果。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
