在原有 “ABC”原则的基础上,基于我国艾滋病防治策略和全球艾滋病防治实践,有专家学者总结推荐预防艾滋病“1A、2B、3C、4D”新原则。具体如下: 1A、2B、3C、4D”新原则 1A:Abstinence Abstinence(禁欲): 具体含义由不发生性行为延伸为:未成...
1. 在恋爱的过程中一定要遵守“1A、2B、3C、4D”原则。 2.可以利用自己的尿液、口腔黏膜渗出液进行艾滋病快速检测,上海已开放多个尿液自检试剂领取点。 3. 如暴露于HIV高感染风险,尽快接受艾滋病病毒暴露后预防(PEP)措施,以降低感染风险。 性传播是HIV病毒主...

Expression of MamQ[G2-11] in MSR-1 ΔmamQ initiated the biosynthesis of very tiny and scarce magnetosomes (Fig. 3c-i, c-ii). mNG-MamQ[G2-11] was localized in several intracellular patches, which distribution resembled that of the particles observed in the TEM micrographs (Fig. 3c-...
【解析】 (a-2b+3c-1)a+2b-3c-1) =(a-1)-(2b-3c)I(a-1)+(2b-3c)] =(a-1)2-(2b-3c)2 =a2-2a+1-(4b2-12bc+9c2) =a2-2a+1-4b2+12bc-9c2.【平方差公式的推导】a+b)a-b)=a2-ab+ab-62=a2-62【平方差公式的内容】两个数的和与这两个数的差的积等于这两个数的平方差.用...
