阻断

The levels of DAG were investigated with radioenzymatic assay, thin-layer chromatography and autoradiography.

上述信号通路的变化效应，可被anti-CD40MAb阻断，这就进一步证实，rCD40L引起的DAG-PKC途径的激活是通过CD40而起作用的。

并利用资料探勘中决策树分类法，建立预测法则，用以判断在监控环境中是否有阻断服务攻击的出现，或是进一步补强误用侦测的缺点。

Some serious skeleton abnormals as above before the Han Tu, descend before the Han Tu and open Han etc. needed to be carried on before the awkward age arrives to correct and cure the development that then can stop wrong Han in early days, the guide tooth, Han bone grew as usual.

有些严重的骨骼畸形如上颌前突、下颌前突、开颌等需要在青春期到来之前进行早期矫治才能阻断错颌的发展，引导牙齿、颌骨正常生长。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。

It looks like this snow will stop the supplies getting through and we shall be hungry for a time, but we've no choice but to tough it out.

看上去这场大雪好像要阻断我们的给养供应，我们得挨饿一段时间了。但我们只有熬过去而没有别的选择。

Objective The aim was to investgate the condition of non-fixed population in area of bilharziasis-spread-block,detect and treat bilharziasis from epidemic area of infectious disease and consolidate the basic achievement.

目的了解和掌握血吸虫病传播阻断地区流动人员情况，及时发现和治疗来自疫区的血吸虫病人，巩固本地成果。

November 9, 2007 — Researchers say that the integrin-transforming growth-factor beta axis is involved in the development of fibrosis and that by blocking integrin beta 6, pulmonary toxicity can be prevented and possibly even reversed. The promising preliminary results testing the new monoclonal antibody being developed by Biogen Idec were presented at plenary here at the 49th annual meeting of the American Society for Therapeutic Radiology and Oncology.

November 9， 2007—研究者表示，整合素转化生长因子β轴（integrin-transforming growth-factor beta axis）包含於发生纤维变性之中，且藉由阻断整合素β6，可以预防肺毒性甚至逆转；此一大有可为的初步结果检验了由Biogen Idec所发展的新的单株抗体，发表於美国治疗放射暨肿瘤学会第49届年会全体会议中。

FDA notified healthcare professionals that pulmonary and disseminated histoplasmosis, coccidioidomycosis, blastomycosis and other opportunistic infections are not consistently recognized in patients taking tumor necrosis factor-α blockers.

FDA提醒医护人员，患者使用肿瘤坏死因子阻断剂与患者发生肺部弥漫型组织浆菌病、球霉菌病、芽生霉菌病及其它伺机性感染的关连尚未被完全证实。

The researchers speculate that caffeine may protect against blepharospasm by blocking adenosine receptors, a mechanism that has also been proposed for its possible preentatie effects on Parkinson's disease.

研究者推测咖啡因通过阻断腺苷受体，一种仍被认为可能有预防帕金森氏症作用的机制，来保护对抗睑痉挛。

"Deodorants only block the signal for a short time," she said.

她表示：「除臭剂只能在短时间内阻断信号的传送。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
