Special attention was directed toward finding inhibitors selective against KDR tyrosine kinase in order to ensure that the in vivo profile of a specific Src inhibitor could be determined. The 4-aminobenzodioxole quinazoline series gave compounds with excellent potency and selectivity.

一直以来，人们为了确保能够在体内测定Src酶专属性抑制剂的特性，把研究焦点放在对KDR酪氨酸激酶选择性的抑制剂的寻找上。4-氨基苯并间二氧五环喹唑啉系列化合物具有极好的效力和选择性。

Omeprazole can be used as an in vivo probe to distinguish subjects between poor and extensive metabolizers of CYP2C19 activity according to the ratios of/-OPZ plasma concentrations after oral administration of the racemate.

本文首次研究了OPZ在中国健康男性受试者体内的立体选择性药代动力学行为，并与文献中的结果进行了比较，旨在深入研究OPZ体内代谢的立体选择性机理。

Selective brachial plexus and lumber nerve roots rhizotomy is a good and effective method to reduce spasticity of upper extrimity.

我们根据臂丛神经功能解剖特点首创设计了选择性臂丛神经根切断术和选择性腰骶神经根切断术治疗脑瘫引起的上、下肢痉挛，取得明显疗效。

Salt stress markedly promoted selective absorption of K+, Ca2+ in root and selective transportation of K+.

盐胁迫显著促进罗布麻根部对K+、Ca2+的选择性吸收和对K+的选择性运输。

Experiment on adaptation effects in cat striate cortex found no pronounced difference between simple cells and complex cells.

结果显示，相对于简单的平动刺激，复杂的光流刺激引起了更显著的适应及后效应：细胞的反应在适应期间及适应后衰减程度更大，多数细胞的方向选择性在适应后发生了显著变化；总体上，细胞对复杂光流的适应具有方向选择性，但细胞对平动刺激的适应与测试刺激的运动方向无关。

The mechanisms underlying these biases of subcortical neurons are still under investigation.

视皮层内较强的方位、方向选择性主要是由视皮层内部机制形成的，而皮层下神经元也具有明显的方位、方向敏感性，并对视皮层神经元的方位、方向选择性有初步的贡献，然而这种皮层下方位、方向敏感性的形成机制仍在进一步的探索中。

We have summarized the recent progress in studies of the regioselectivity for the P-B reaction in this paper, and especially focused on the temperature and substituent effects on the regioselectivity.

本论文结合作者的研究工作，评述了近年来P-B反应的区域选择性的研究进展，重点阐述了反应温度、反应物的取代基对P-B反应区域选择性的影响及其规律。

The extent of inhibition of depolarization by superfusion of ethanol for 5 minutes was 41.8±3.3 ％(n=17). The addition of 5 nM and 20 nM KT5720 (a selective protein kinase A inhibitor) and 250 μM H9 dihydrochloride (a non-selective protein kinase inhibitor), into the intracellular solution significantly attenuated the inhibitory effects of ethanol.

当分别将5 nM或20 nM KT5720（选择性蛋白质激酶A抑制剂）或250 μM H9 dihydrochoride（非选择性蛋白质激酶抑制剂）置入细胞内液时，乙醇的抑制作用明显被减弱；但乙醇的抑制作用不受到5 nM或20 nM calyculin A（磷酸酶1/2A抑制剂）的影响。

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）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
