But NO is a hardly dissolvable gas, it's half-time in tissue is only about 10 seconds.

但NO是一种极难溶于水的气体，其在组织中的半衰期仅有10-60s，其反应活性取决于它被去除或破坏的速度。

Disubstituted 2-isoxazolines were oxidized to corresponding isoxazoles by NO in dichloromethane.

3、3，5-二取代的-2-异恶唑啉在NO作用下可以发生芳环化反应，生成对应的2-异恶唑化合物。

Disubstituted 2-isoxazolines were oxidized to corresponding isoxazoles by NO in dichloromethane.

所以反应的反应过程是受溶剂控制的。3、3，5-二取代的-2-异恶唑啉在NO作用下可以发生芳环化反应，生成对应的2-异恶唑化合物。

No marks for guessing who might fill into the shoes of wicked brothers of duryodhana.

No标志着在猜谁可能补到鞋的邪恶兄弟

During the whole course of the dynamitic development and evolvement of redox zones, concentrations of TOC, sulfide, NH+4-N, HCO-3, CO2 and Fe2+ increased with time and decreased with distance; concentrations of NO-3 and DO decreased with time and increased with distance; SO2-4 concentration decreased first and then increased over time; but decreased with distance.

在氧化还原带的整个演化过程中，各带中TOC、硫化物、NH+4-N、HCO-3、CO2和Fe2+等物质的浓度随时间的推移而升高，随离污染源距离的增加而降低；NO-3和DO等物质的浓度随时间的推移而减小，随离污染源距离的增加而升高；SO2-4的浓度则随时间的推移先减小而后增加，随离污染源距离的增加而降低。

Nitro-compound such as sodium nitroprusside is used as donor of ectogenic NO in the study.

研究外源性NO对NSCs的调控作用常用硝普钠等硝基化合物作为供体。

However, so far the relationship between H2S and NO in endotoxic shock is still confusing.

但是H2S在内毒素休克中的作用与NO有何关系报道较少且尚有争议。

As an immunomodulator NO may play a role like a double-edged sword since it expresses both in immuonchalleged and immunosspresed states. 2. After received external stimulus the morphology of ependyma of SFO could be changed and varied with time course, particularly its cellular apoptosis do occur and earlier than the ordinary areas of the brain. 3. Astrocytes in SFO could express cFos protein induced by LPS, suggesting the cells may maintain homeostasis in the brain in a longer period and modulate immune state of the brain. 4. As a CVO, SFO may sense changes of blood-bearing immunosignals earlier and instantly response to them, thus as one of windows of the brain SFO do take part in immunomodulation within the brain.

通过我们的实验结果我们可以得出这样一些初步的结论：1、一氧化氮作为免疫调质参与了机体免疫，它既能在免疫激发状态下又可在免疫抑制状态下进行表达提示，NO在脑内免疫调节中的作用可能是双向的。2、穹窿下器的室管膜形态在接受外界刺激后，随着时间的变化而不同，扫描电镜下的凋亡形态虽需进一步证实，但室管膜细胞确实发生了凋亡，并且穹窿下器发生的较早。3、穹窿下器内的星形胶质细胞在给予大肠杆菌后确实可以表达c-fos蛋白，并可能通过自身的激活来较长时间的维持体液的动态平衡，调节脑内免疫状态。4、穹窿下器作为感受性室周器官之一，能够较早的感受血携免疫信息的改变并及时作出反应，可能作为外周免疫信息进入脑内的窗口之一来参与脑的免疫调节。

NO of Notch are the first two letters in Nordic, CH are the first two letters in China, and the T can be interpretated as a + equalling to plus; altogether, the word speaks for itself.

NOTCH中的前两个字母NO也是是北欧这个单词的前两个字母，CH是中国的前两个字母，而T则可以被解释为&+&的意思。NOTCH这个词的组成表达了它的含义。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
