查询词典 receptors

By exchanging the carboxyl termini of NR2A and NR2B subunit, surface NR2B-containing NMDA receptors occurred more in a clustering manner,whereas NR2A-containing ones more diffusedly.

然而，NR2亚单位中与这些支架蛋白相结合的功能区却无法直接解释NR2A与PSD-95蛋白之间的这种特异性的相互作用。

Given this finding, it seems likely that the mechanism underlying response to fluoxetine in patients with premenstrual dysphoric disorder is distinct from that postulated for major depression, which involves postsynaptic downregulation of serotonergic receptors over a period of weeks.

假设这一发现是正确的，则fluoxetine治疗月经前焦虑障碍的机制可能与治疗严重抑郁症不同，后者与突触后血清素激活受体的下调节有关联且维持数周的期间。

Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现&低促高抑&的规律，且茎叶浸提液作用效应大于根系浸提液。

From the above results,it might be possible that the SP,which reacts on the SP receptors in the endangium of cochlear micrangia,come mainly from the blood and the endothelial cells.

作用于耳蜗微血管内膜SP受体的SP，主要来源于血液及内皮细胞自身。

In eukaryotic cells,Toll-like receptors in endosomal membrane were show to recognize viral RNA in endosome and thereby initiate innate immunity pathways for virus resistance.By contrast,a cytosolic RNA receptor protein, RIG-Ⅰ(retinoic acid inducible gene-Ⅰ),has recently been identified for recognition of the viral RNA.

在真核生物体内，除了定位于内吞体膜上的TOLL样受体能够识别入侵机体的病毒RNA，启动机体抗病毒的固有免疫反应外，近年来发现了另一种能够识别病毒RNA的细胞质内受体——RIG-Ⅰ。

However, high level of UEA-1 receptors had been found in the glandular and luminal epithelium of estrous canine uterus.

UEA-1受体在休情期犬子宫内未见表达，而在发情期犬子宫内膜腔上皮和腺上皮内的表达量很高。

The main factors that affected the aiponectin concentration included types of the bioactivity of adiponectin complex; the variance of age, sexuality and race; the change of leptin, tumor necrosis factor-α, glucocorticoid, cAMP and β-adrenoceptor excitomotor, NO and so on; bioactivity of receptors of adiponectin.

运动对脂联素影响方面的研究，结果有很大的不同，有人认为运动训练虽然能够改善糖尿病患者或代谢综合征的胰岛素抵抗，但并不能提高脂联素的水平；还有的研究者认为，运动训练改善胰岛素敏感性和运动训练改善了血浆中脂联素的浓度有关。

Microinjection of histamine into the third cerebral ventricle can produce excitory effect on respiratory activities of guinea pigs possibly via H1 receptors.

第三脑室微量注射组胺有兴奋呼吸的作用，该作用可能是由组胺H1受体所介导的。

But the existence, structure and localization of plant GABA receptors are needed to be further studied all the same.GABA could decrease relative exosmic ratio of radicle and coleoptile, enhanced the content of endogenous soluble sugar, proline and betaine, promoted the absorb of K+, excluded Na+ coming in the root, stem and leaves of maize seedling, increased K7 Na+ ratio under salt stress.

GABA类似物及动物GABA受体拮抗剂能够略微减弱GABA的生理学效应，动物GABA受体激动剂略微增加GABA的生理学效应，暗示植物可能也象动物一样存在GABA受体。

First, we observed the effects of extogenous IL-15 on Jurkat cells which express IL-15 receptors.

首先，我们观察了外源性IL-15对表达IL-15受体(IL-15R)的人类T细胞白血病细胞系Jurkat细胞的体外影响。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.
