    Simple Program to Investigate Hysteresis Damping Effect of Cross-Ties on Cables Vibration of Cable-Stayed Bridges by Panagis G. Papadopoulos, Andreas Diamantopoulos, Haris Xenidis, Panos Lazaridis

    Published 2012-01-01
    “…A short computer program, fully documented, is presented, for the step-by-step dynamic analysis of isolated cables or couples of parallel cables of a cable-stayed bridge, connected to each other and possibly with the deck of the bridge, by very thin pretensioned wires (cross-ties) and subjected to variation of their axial forces due to traffic or to successive pulses of a wind drag force. …”

    靶向Cdc6 RNAi抑制舌癌CAL-27细胞的增殖

    Published 2011-01-01
    “…【目的】 应用RNA干扰技术,靶向抑制舌癌细胞中Cdc6的表达,观察舌癌细胞增殖凋亡等改变,初步探讨下调Cdc6表达抑制舌癌细胞增殖的分子机制【方法】 实验分4组:空白对照组CON,阴性对照组NC,实验组KD1和KD2应用前期构建的Cdc6的慢病毒载体,转染舌癌CAL-27细胞,通过Real time RT-PCR和Western blot法检测Cdc6 mRNA及蛋白的表达;以MTT法测定活细胞数并绘制细胞生长曲线;利用流式细胞仪观察细胞凋亡【结果】 慢病毒载体转染CAL-27细胞后,Real time RT-PCR和Western blot实验结果显示:舌癌CAL-27细胞中Cdc6的表达明显被抑制,相对NC组,KD1KD2组对Cdc6基因敲减效率分别为55.60%和64.38%蛋白表达分别降低44.44%和66.67%;细胞生长曲线表明,细胞生长明显减缓,KD1和KD2组细胞生长抑制率分别为33.68%和35.79%;流式细胞仪检测细胞周期显示:KD1组KD2组两组细胞凋亡率较NC组均有显著上升,分别为57.55%和83.81%【结论】 靶向Cdc6慢病毒载体RNA干扰能有效抑制舌癌CAL-27细胞的DNA复制,阻止舌癌细胞的增殖…”
