The protein which act on the phosphated tyrosine receptor kinase is phosphoinsitol 3 kinase , phospholipase C gamma and connective protein Shc, at last the signals can be transferred.

与酪氨酸磷酸化的Trk A相互作用的蛋白质是磷脂酶Cγ和磷脂酰肌醇(-3)激酶(PI3K)，及连接蛋白质Shc，最终传播NGF信号。

In the second experiment, we would like to understand the relationship between sexual performance and sexual motivation. The partner preference test was conducted to measure sexual incentive motivation, and tyrosine hydroxylase immunohistochemistry was used to assay the dopaminergic neuron activity in the medial preoptic area.

在第二部份实验所探讨的是雄鼠的性动机与性表现两者之关系，本实验以EGb 761作为一实验工具，利用伙伴偏好试验测试雄鼠性诱因动机，并利用酪氨酸羟化酶(tyrosine hydroxylase， TH)免疫化学染色方法分析内侧视前区多巴胺神经元的活性。

Results: The Fos-like immunoreactive neurons distributed mainly in the spinal trigeminal subnucleus caudalisipsilaterally and medullary visceral zone (MVZ,including nucleus tractus solitarius,ventrolateral medulla and the reticular formation between the first two),ln the sections processed for double staining of Fos and TH immunohisto chemistry, numerous Fos-LI neurons showed also TH- like immunoreactivity in their cytoplasm(Fos-TH cells)in MVZ.

结果：Fos样免疫反应神经元主要分布在同侧三叉神经脊束核尾侧亚核、双侧延髓内脏带(孤束核、腹外侧区及二者之间的网状结构)。在抗Fos 和抗酪氨酸羟化酶的双重免疫染色切片上，见到延髓内脏带内许多Fos阳性神经元的胞浆同时呈TH样免疫反应(Fos-TH双重阳性细胞)。

AIM: To study the effect of sesamin on expression of inducible nitric oxide synthaseand nitrotyrosinein rat liver tissue with metabolic syndromic hepatic steatosis.

目的： 观察芝麻素对代谢综合征性脂肪肝大鼠肝组织诱导型一氧化氮合酶及硝基酪氨酸表达的影响。

Elevated levels of phosphatase and tensin homolog deleted on chromosometen have been reported in mammary gland tumors in humans.

有关酪氨酸磷酸酶基因(Phosphatase and tensin homolog deleted on chromosometen，PTEN)在乳腺肿瘤中的检测在人医早有报道。

AIM: To investigate whether celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, potentiates the anti-leukemia activity of STI571 in K562 cells METHODS: K562 cells were treated with STI571, celecoxib or combination of both at different concentrations in suspension culture.

目的：探讨环氧合酶－2(COX-2)抑制剂塞来昔布促进酪氨酸激酶抑制剂STI571的抗白血病效应及其机制。

Receptor tyrosine protein kinase is one of key kinases in cell signal transduction and plays an important role in the process of cell growth, development and functions regulated by growth factors.

受体酪氨酸蛋白激酶是细胞信号转导进行的关键信号酶，在生长因子调控细胞生长、发育与功能的过程中起着重要的生理作用。

It is proposed that tyrosine residues are involved in the active site of CTA and they are crucial in recognition and binding of ribosomal RNA.

这些结果表明酪氨酸残基可能位于cinnamomin A链的RNA N-糖苷酶活性中心，并且它们在识别和结合核糖体RNA的过程中有重要作用。

However, the involvement of tyrosine kinase either directly or through the prostaglandins and nitric oxide synthase in response to inflammation during diabetes is not completely understood.

不过，酪氨酸激酶是直接参与还是通过前列腺素和一氧化氮合酶对糖尿病炎症产生反应的，我们目前还不知道。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
