| 1 | Resveratrol protects PC12 cells against OGD/ R-induced apoptosis via the mitochondrial-mediated signaling pathway显示文摘在这研究,我们对导致的氧葡萄糖 deprivation/reoxygenation (OGD/R ) 调查了 resveratrol 的 neuroprotective 潜力在区分得好的 PC12 房间和内在的机制的 apoptotic 损坏。房间当面在正常状况或 OGD/R 下面被孵化或 10 M resveratrol 的缺席。房间生存能力与 methyl-thiazolyl-tetrazolium (MTT ) 被决定试金。Apoptotic 比率与 Hoechst 33342 染色和 Annexin V-FITC/PI 两倍染色被决定。氧化应力被测量细胞内部的反应的氧评估 superoxide dismutase (草皮) 和过氧化氢酶(猫) 的种类(ROS ) , mitochondrial superoxide, malondialdehyde (MDA ) 内容,和这些活动。细胞内部的钙([Ca 2+]i) 被 Fluo-3/AM 估计。mitochondrial 膜潜力(MMP ) 被 5,5,6,6-tetrachloro-1,1,3,3-tetraethyl-benzimidazolyl-carbocyanine 碘化物(JC-1 ) 和玫瑰精评估 123 (Rh123 ) 。mitochondrial 渗透转变毛孔(MPTP ) 的开始被 Calcein/Co 2+-quenching 技术决定。细胞色素 c, Bcl-2, Bax,劈开的 caspase-9,和劈开的 caspase-3 的蛋白质层次被西方的污点分析检测。结果证明 10 M resveratrol 稀释了 OGD/R-induced 房间生存能力损失和房间 apoptosis,它在在 SOD 和猫活动的 MDA 内容和增加与减少被联系。而且,细胞内部的 ROS 和 mitochondrial superoxide 的累积,骚乱[Ca 2+]i 动态平衡, MMP 的减小, MPTP 的开始,和在 OGD/R-injured 房间观察的 mitochondrial 细胞色素 c 的版本,在调停 mitochondrial 的 apoptotic 小径上显示了一个开关,都被 resveratrol 颠倒。这些结果建议 resveratrol 管理可以经由 modulating 起一个 neuroprotective 作用在 OGD/R-induced PC12 房间损害的调停 mitochondrial 的发信号小径。 | Xuan Liu Xiangyang Zhu Miao Chen Qinmin Ge Yong Shen Shuming Pan | 2016 | Acta Biochimica et Biophysica Sinica2016，48，4： | 8 |
| 2 | Recent advances in nanorobotic manipulation inside scanning electron microscopes显示文摘A scanning electron microscope(SEM)provides real-time imaging with nanometer resolution and a large scanning area,which enables the development and integration of robotic nanomanipulation systems inside a vacuum chamber to realize simultaneous imaging and direct interactions with nanoscaled samples.Emerging techniques for nanorobotic manipulation during SEM imaging enable the characterization of nanomaterials and nanostructures and the prototyping/assembly of nanodevices.This paper presents a comprehensive survey of recent advances in nanorobotic manipulation,including the development of nanomanipulation platforms,tools,changeable toolboxes,sensing units,control strategies,electron beam-induced deposition approaches,automation techniques,and nanomanipulation-enabled applications and discoveries.The limitations of the existing technologies and prospects for new technologies are also discussed. | Chaoyang Shi Devin K Luu Qinmin Yang Jun Liu Jun Chen Changhai Ru Shaorong Xie Jun Luo Ji Ge Yu Sun | 2016 | Microsystems & Nanoengineering2016，2，1： | 4 |
| 3 | Adaptive cubature Kalman filter with the estimation of correlation between multiplicative noise and additive measurement noise显示文摘Mobile robots are often subject to multiplicative noise in the target tracking tasks,where the multiplicative measurement noise is correlated with additive measurement noise.In this paper,first,a correlation multiplicative measurement noise model is established.It is able to more accurately represent the measurement error caused by the distance sensor dependence state.Then,the estimated performance mismatch problem of Cubature Kalman Filter(CKF)under multiplicative noise is analyzed.An improved Gaussian filter algorithm is introduced to help obtain the CKF algorithm with correlated multiplicative noise.In practice,the model parameters are unknown or inaccurate,especially the correlation of noise is difficult to obtain,which can lead to a decrease in filtering accuracy or even divergence.To address this,an adaptive CKF algorithm is further provided to achieve reliable state estimation for the unknown noise correlation coefficient and thus the application of the CKF algorithm is extended.Finally,the estimated performance is analyzed theoretically,and the simulation study is conducted to validate the effectiveness of the proposed algorithm. | Quanbo GE Zhongcheng MA Jinglan LI Qinmin YANG Zhenyu LU Hong LI | 2022 | Chinese Journal of Aeronautics2022，35，5： | 1 |
