阻断

Microinjection of norepinephrine (NE, 30 nmol) into the subnucleus commissuralis of nucleus tractus solitarii of rabbits evoked a decrease of mean arterial pressure and heart rate. These effects were attenuated by application of naloxone (3 nmol) on the same area,which by itself showed no effect on MAP and HR.

于杂种白兔的孤束核联合亚核内微量注射去甲肾上腺素，引起血压降低和心率减慢，将小剂量阿片受体阻断剂纳洛酮注入CNTS，本身不影响血压与心率，但减弱NE在CNTS中的降压降率幅度。

We tested whether inhibitory GABAergic synaptic transmission regulates Xenopus optic tectal cell dendritic arbor development in vivo by expressing a peptide corresponding to an intracellular loop ofthe gamma2 subunit of type A GABA receptors GABA(AR, which is required to anchor GABA receptors to the postsynaptic scaffold.

我们想证明如下设想：抑制性GABA能突触传递是否能调节早蟾视顶盖细胞的树突发育。因为GABA受体的gamma2亚基有一段细胞内的跨膜端序列，这段序列对锚定GABAA受体到突触后膜是必须的，所以我们的主要方法是设计了一段特异性的争对细胞内段的序列，这样就特异性的阻断了单个细胞GABA能的突触传递。

Ansochromogenes was transformed by pUC1169 from itself. 8 mutants lost ability to produce nikkomycin were screened from 4068 colonies of Vio〓 Thio〓 with Tn4560 transposition. Southern blotting suggested that Tn4560 was inserted in at least 4 positions of chromosomal DNA in S.

于39℃，MM／Vio条件下培养携带有pUC1169的7100孢子，Tn4560发生转座；筛选到4068个转座菌落，并从中得到8株尼可霉素阻断突变株；对这8株突变株的总DNA进行Southern杂交分析表明，Tn4560至少在4个不同的位点插入到7100的染色体上。

Interruption of tonically actie medullo-spinal pathways after injury causes disinhibition of thoracolumbar sympathetic preganglionic neurons, and intraspinal sprouting of nere growth factor-responsie primary afferent fibers is thought to contribute to their hyperactiity.

阻断损伤后增强活化的脊髓传导通路可引起胸腰段交感节前神经元激活，椎管内神经生长因子萌发；敏感的初级传入纤维被认为可促使胸腰段交感节前神经元功能亢进，促进NGF生成增多。

In normal growth conditions, the RNR3 promoter is transcriptionally silent.

在正常生长条件下，RNR3基因不转录，当酵母细胞DNA受损伤，如UV、MMS作用；或是DNA合成阻断剂如HU都可以诱导RNR3的转录。

The associated factors, clinical signs, treatment and prognosis were discussed. Result: Nine patients (6 female and 3 male) were included in this study. All of the patients were associated with myopia, ranging from -0.5 diopters to -5.0D. Gonioscopy revealed a dense homogeneous pigmented band seen over the entire circumference of the trabecular meshwork in all patients; however, no patients with iris transillumination defects were detected. Two of the patients developed pigmentary glaucoma and were treated with β-blocker, miotics and argon laser trabeculoplasty.

结果：九病例中有六位女性及三位男性，所有的病例皆有近视，分布於负零点五至负五点零屈光度，所有的病例在隅角镜检查皆可观察到浓厚的色素沈积在小梁组织，然而在这些病例并没有发现到有典型之虹膜透光缺损：其中有两例后来发展成色素性青光眼，以乙型阻断剂、缩瞳剂和氩氮雷射小梁整形术治疗后，病情控制稳定。

By transcriptomic analysis, we found that there were 128 genes had both the sense and anti-sense transcripts our previous CB EST data. Unexpectedly, fifteen proteins with the corresponding antisense RNAs were identified in the proteomic study, implying that these sense RNAs could be translationally expressed, without being completely interrupted by the antisense RNAs.

在转录组中有128个基因的反义转录本以及相应的正义转录本序列，我们意外地发现，具有反义转录本的15个蛋白质出现在蛋白质组数据中，这个有趣的现象说明在反义转录本存在的条件下，正义转录本可以转录表达，而没有完全被反义转录本阻断。

One role of DNA methylation is to turn off repetitive genes, such as transposable elements that can move or spread throughout a genome and disrupt other gene functions if left unchecked.

DNA甲基化的一个作用就是关闭一些重复的基因，例如一些在不加抑制的情况下能转移或者延伸到基因组的其他地方去阻断基因的转座子。

Objective: To evaluate the protection of reduced glutathione and clinical therapeutic efficacy in patients with partial hepatectomy accompany with blocking fossa transversalis hepatic blood flow.

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。
