| 1 | miR-27b inhibits gastric cancer metastasis by targeting NR2F2显示文摘增加的注意在癌症过程集中于 miRNAs 的下面规定。原子受体亚科 2 (NR2F2,也作为 COUP-TFII 知道) 涉及癌症的许多类型的发展,但是它在胃的癌症的角色留下逃犯。在这个实验, oncomine 和 Kaplan-meier 数据库表明 NR2F2 在胃的癌症是起来调整的并且高 NR2F2 表示贡献了差的幸存。MicroRNA-27b 被指向并且由在人的胃的癌症纸巾和房间的 NR2F2 下面调整。miR-27b 的宫外的表示在 vitro 并且在 vivo 禁止了胃的癌症房间增长和肿瘤生长。试金建议 miR-27b 的 overexpression 能支持 MGC-803 房间移植和侵略并且延迟他们的转移到肝。另外, miR-27b 的下面规定在 vitro 提高了 GES-1 房间增长和转移。这些调查结果表明 miR-27b 为改进病人是在胃的癌症和 biomarker 的肿瘤 suppressor 幸存。 | Qingzhao Feng Xionglin Wu Fuchao Li Beibei Ning Xiaofeng Lu Yin Zhang Ying Pan Wenxian Guan | 2017 | Protein & Cell2017，8，2： | 16 |
| 2 | Water presence detection in a concrete crack using smart aggregates显示文摘Liquid migrating into existing concrete cracks is a serious problem for the reliability of concrete structures and can sometimes induce full concrete structural failures.In this paper,the authors present recent research on water presence detection in concrete cracks using piezoceramic-based smart aggregate(SA)transducers.The active sensing approach,in which one piezoceramic transducer is used to generate stress waves and others are used to detect the stress wave responses,is adopted in this research.Cracks formed in concrete structures act as stress reliefs,which attenuate the energy of the signals received by the SAs.In case of a crack being filled with liquid,which changes the wave impedance,the piezoceramic transducers will report higher received energy levels.A wavelet packet-based approach is developed to provide calculated energy values of the received signal.These different values can help detect the liquid presence in a concrete crack.A concrete beam specimen with three embedded SAs was fabricated and tested.Experimental results verified that the SA-based active sensing approach can detect a concrete crack and further detect the liquid presence in the concrete crack. | Qingzhao Kong Qian Feng Gangbing Song | 2015 | International Journal of Smart and Nano Materials2015，6，3： | 1 |
