fluid shear stress meaning in Chinese
流体切应力
Examples
- Results ( 1 ) el - 8 mrna did not express in huvecs untreated with fluid shear stress
23dyne儿m勺时k七inrna表达量时为1 - The expression ratios reported are the average from the two separate experiments . ( 1 ) huvecs exposed to fluid shear stress ( 4 . 20 dyne / cm2 ) for 1 h , 2 h , 3 h , 4 h , 5 h , 6 h , 7 h , 8 h , 9 h , 10 h , or 12 h , respectively
735x10 ’拷贝，与3h时的表达量处在同一个数量级；在7dh之间h七inrna的表达量相对稳定，但和4 ? 6h之间n - ( 4 ) huvecs exposed to low fluid shear stress ( 4 . 20 dyne / cm " ) for 2 h and incubated by 17 p - estradiol ( 10 - 7 m ) + low shear stress ( 4 . 20 dyne / cm2 , 2 h ) . normal static cultured huvecs were selected as a control
929x10 ’拷贝之间，和44h之间neinrna的表达量相比又下降了一个数量级；未用切应力处理的内皮细胞没有il七基因的表达，基线值分别为8 - On this condition , we exert two different levels of fluid shear stress ( 4 dyns / cm2and 15 dyns / cm2 ) to them by a parallel plate flow chamber and observe the change of apoptosis of endothelial cells by tunel . we demonstrate that high level shear stress can inhibit the apoptosis induced by lps , whereas low level shear stress was less effective
在此基础上，将两种不同大小剪切力与lps共同作用于细胞，发现高水平剪切力( 15dyn cm ~ 2 )可以抑制lps诱导的凋亡，而低水平剪切力( 4dyn cm ~ 2 )的效果则不明显。 - From the view of cellular rheology , we examined the influence of fluid shear stress on the metabolism , morphology , structure and function of endothelia cells in our previous research . it is first time for us to develop the research between shear stress and apoptosis . in this study , we stimulate the human umbilical venous endothelial cells ( huvec ) by lps and apply different levels of fluid shear stress to them by a parallel plate flow chamber , then observe the change of apoptosis of endothelial cells by terminal deoxynucleotidyl transferase mediated dutp nick end labeling ( tunel )
我们从细胞力学的角度，曾对血管内皮细胞在剪切力作用下的代谢、形态、结构及功能等进行过系统研究，但剪切力与内皮细胞凋亡的相关研究尚属首次，我们希望通过探讨细胞凋亡与剪切力大小及作用时间的关系，为探索剪切力对血管内皮细胞信号转导的影响及作用机理提供有价值的参考数据和实验资料。
