Next, I detected the expression of E-cadherin, an important adhesion molecular mediating the adhesion among epithelia cells.

细胞间的粘附是由粘附分子介导的，E-cadherin是介导上皮细胞间粘附的重要粘附分子，其表达与功能的丧失与多种肿瘤的转移呈负相关。

Most parameters for the mixture antioxidation oil were studied and they were consistent with GB 2536-90, including transparence, smell, density, solidifying point, flash point, viscosity, acids and water-solubility acids;The viscosity of the antioxidation oil at 20℃～90℃was as same as mineral;And the relative permittivity at 30～106Hz was invariable and it was higher than mineral oil so that the electric field of the antioxidation oil paper insulation was more equilibrious.

研究得到了所研制的抗老化变压器油的参数值：透明度、气味、密度、凝点、闪点、运动粘度、酸值及水溶性酸或碱等，均满足变压器油技术标准GB 2536-90的要求；20℃～90℃之间该油运动粘度和矿物油几乎相等；在30～106Hz频率范围内，该油相对介电常数基本维持恒定，且比矿物油相对介电常数略大；其工频击穿电压远高于矿物油。

Highly ordered mesoporous carbon,denoted as CMK-5,was synthesized by using mesoporous silicates SBA-15 as template and furfuryl alcohol as carbon precursor.

以介孔硅SBA-15为模板，糠醇为碳源制备了高度有序的介孔碳(CMK-5)，并用微波法合成碳负载的铂纳米粒子的催化剂。

However, the mutation of GATA site at -2948bp remarkably reduced the reporter gene activity driven by SV40 promoter, but not by ε-globin gene proximal promoter. To test whether those sites act synergistically, we mutated 2 of these three binding sites with different combinations.

然而，GATAb（在-2948bp的GATA位点）的突变明显地降低了SV40启动子介导的报告基因转录活性，但是对ε-珠蛋白基因启动子介导的报告基因表达却影响不大。

The results showed that either higher or lower parasitic density of glochidia, either longer or shorter parasitic time, the quantity of glochidia infested on yellow catfish and grass carp was obviously higher than that on silver carp, bighead and crucian carp.

选用黄颡鱼、草鱼、鲢、鳙和鲫作为三角帆蚌的寄主鱼，分析了寄苗悬液钩介幼虫密度和寄苗时间对5种鱼初始寄苗量的影响，并对寄生在这5种鱼上的钩介幼虫发育情况进行了观察。

Purpose:To study the effect of IL-6,IL-1 and PDGF on the growth of rat glomerular mesangial cells in vitro.

目的：探讨白细胞介素-6(IL-6)、白细胞介素-1(IL-1)和血小板源生长因子对大鼠肾小球系膜细胞增殖的影响。

The addition of SiCN powder to Sialon increases the glutinosity of glass formed during sintering process by additives and SiO2 film on the surface of Si3N4, and lowers the sintering densities of the samples.

SiCN／Sialon复合材料复介电常数的实部和虚部均随纳米SiCN含量的升高而增大，但是低于预期值，其原因是由于长时间高温烧结时，纳米SiCN结构发生变化，其复介电常数的实部和虚部大幅度下降造成。

The genus specificity was validated with 47 strains including wild type isolates. Preliminary screening of soil samples with Gordonia-specific primers was successful in the rapid detection of the presence of 36 Gordonia wild-type isolates.

经多序列分析比对软体计算并比较gyrB基因序列，可知Gordonia菌属与7种邻近放线菌的gyrB基因序列相似度介於72.8-82.1%，而在16S rDNA序列相似度则介於90.0-95.4%，gyrB基因可明显区分Gordonia菌属与其他属之放线菌。

Thus gp130 is the common signal transduction molecule. Gp130 molecule expresses universally on many tissues including immune system, hemapoietic system, and nerve system. Gp130 has an essential role in the function and regulation of the above systems, especially in the development of hemapoietic system. The signal transduced by gp130 is necessary during the differentiation and proliferation of hemapoietic cells. It is evidenced that the embryo of gp130 gene-knockout mouse was dead due to a serious impediment of the development of hemapoietic system.

Gp130在人体组织细胞上广泛性表达，介导和调节机体的免疫、造血以及神经系统的生理功能，尤其是在造血系统的发育过程中，具有极其重要的作用，动物实验表明，敲除小鼠的gp130分子基因可以使其在胚胎的早期阶段产生严重的造血系统障碍，最终导致流产，由此表明在造血细胞的分化、发育和生物学行为中，gp130介导的信号是必不可少的。

Methods The interleukin-2 and soluble interleukin-2 receptor(SIL-2R) in 30 cases of recurrent simple herpetic keratitis experimental group and 25 cases of healthy persons were determined.

本文测定了30例复发性单纯疱疹性角膜炎患者和25例健康人血清白细胞介素-2(IL-2)及其可溶性白细胞介素-2受体(SIL-2R)的水平。

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％。
