查询词典 receptors

These result suggested that the enhancement of the cardiovascular activities mediated by muscarinic receptors in the rVLM after administration of cholinomimetic drugs or adrenal corticoids and the maintaining of basal cadiovascular activities are related to the activation of calcium channels.

提示由N-受体介导的毒扁豆碱及肾上腺皮质激素对心血管活动的正性调节作用以及正常血压的维持均与rVLM区有关心血管神经元细胞膜上钙通道的活动有关。

ECL and PHAL receptors maintained a lower level at day 4 and 5 of pregnancy than those at the diestrus.

d的水平显著低于动情间期和动情期（P＜0.01）。

The level of the ECL and the PHAL receptors were higher at the estrus than at diestrus.

Upon FGF binding, specific membrane receptors dimerize and autophosphorylate, then activate several downstream signaling pathways including Ras-MAPK.

FGF通过结合细胞表面的FGF受体，使其二聚化并自体磷酸化，活化后的FGF受体具有酪氨酸激酶活性，进而活化胞内下游多条信号通路。

Uponligand stimulation,c-kit receptors dimerize,activate its intrinsic tyrosine kinase,andautophosphorylate.

在配体的刺激作用下，c-kit受体发生二聚化，激活内源性酪氨酸激酶，并发生自身磷酸化。

Recently, many studies have revealed that G Protein-coupled receptors exist as dimmers, which may be present homo-or heterodimers/oligomers.

近年来，大量研究发现G蛋白偶联受体不仅以单体形式，而且以同源或异源二聚体形式存在。

Methods Wistar rats were chosen as donators, and SD rats as receptors.

方法Wistar大鼠的后肢为移植物，SD大鼠为受体。

Low-dose naltrexone, at higher doses may block the endorphin and enkephalin receptors, about 3 or 4 hours to eliminate from the body - but the elevated concentrations of endorphin and enkephalin One day can be maintained.

低剂量纳曲酮，在较高剂量时可阻断内啡肽和脑啡肽对受体的作用，大约3或4小时内从体内消除--但升高的内啡肽和脑啡肽浓度可维持一天。

Angiogenesis is regulated by signals derived from receptors for both growth factors and ECM molecules. Recent studies have shown that activation of ERKs is closely involved in the migration or tubular-like formation of endothelial cells and induced by various angiogenic factors.

血管新生可以受到许多来自於生长因子受器及胞外基质受器的讯息所调控，而近年的研究也显示ERK的活化不但会受到许多促血管新生因子的诱导，而且跟内皮细胞的移型及管状形成作用有很大的关系。

There are in fact glutamate receptors in every major human organ.

在每一个主要人体器官中都有谷氨酸受体。
