	Apoptosis induction and G2/M arrest of 2-methyl-1,3,6-trihydroxy-9,10-anthraquinone from Rubia yunnanensis in human cervical cancer HeLa cells 期刊论文 OAI收割 PHARMAZIE, 2013, 卷号: 68, 期号: 4, 页码: 293-299 作者: Zeng, Guang-Zhi; Fan, Jun-Ting; Xu, Jun-Ju; Li, Yan; Tan, Ning-Hua 收藏 \| 浏览/下载：44/0 \| 提交时间：2015/05/14 2-Methyl-1,3,6-trihydroxy-9,10-anthraquinone (MTA) one of the major components isolated from the traditional Chinese medicine Rubia yunnanensis exhibited inhibitory activity on the proliferation of several human cancer cell lines. The results from an annexin V-FITC (fluoresein-5-isothiocyanate) apoptosis assay and DNA content analysis showed that MTA exerted cytotoxicity via apoptosis induction and G2/M cell cycle arrest in human cervical carcinoma HeLa cells. Further MTA was found to induce apoptosis of HeLa cells through the mitochondria-mediated pathway. It caused the translocation of Bax to the mitochondria and release of cytochrome c into the cytosol which caused the cleavage of caspase and poly(ADP-ribose) polymerase and finally triggered the apoptosis. Furthermore the p53/p21/Cdc2-cyclin B1 signaling was found related to the G2/M arrest caused by MTA. The over-expression of p21 and down-expression of cyclin B1 caused by MTA inactivated the Cdc2-cyclin B1 complex of G2/M checkpoint and finally caused the G2/M arrest in HeLa cells. This study demonstrated that MTA is a potential anti-cancer component of R. yunnanensis a folk anti-cancer herb used in Yunnan China.

	3R intersection target positioning in real time based on distance (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China Nengwei W.; Juan C.; Jian C. 收藏 \| 浏览/下载：13/0 \| 提交时间：2013/03/25 The positioning error based on angle angle-distance or single station positioning increases with the distance increasing. 3R target positioning based on distance can obtain the high precision measurements in long distance. Here we give the 3R model for the intersection positioning provide the two necessary conditions for getting the optimum intersection point. The experimental results show that the intersection precision based on angle is over 2m and will degrade greatly with the increasing of distance while the one based on 3R model will improve and the error decrease gradually. That the precision of the distance measurement is about 1m means the 3R model is better than the angle positioning which can compensate the drawbacks of the angle positioning at short distance. 2010 IEEE.
	Characteristics of ZnMgO-based metal-semiconductor-metal photodetectors (EI CONFERENCE) 会议论文 OAI收割 International Symposium on Photoelectronic Detection and Imaging, ISPDI 2007: Photoelectronic Imaging and Detection, September 9, 2007 - September 12, 2007, Beijing, China 作者: Zhang J.; Li B.; Li B.; Li B.; Zhao Y. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 In recent years ZnMgO semiconductor alloys with a direct bandgap tunable between 3.37 eV and 7.8 eV become one of the most suitable materials for the fabrication of ultraviolet detectors. In this paper we have fabricated metal-semiconductor-metal photodetectors on 1-m thick Zn 0.8Mg0.2O films. The interdigital metal electrodes are 500 m long and 5 m wide with an interelectrode spacing 2 m 5 m and 10 m respectively. Zn0.8Mg0.2O films were grown on quartz by ratio frequency magnetron sputtering at 500C. Dark current spectral responsivity and pulse response were carried out for the devices with different finger pitches. All the photodetectors showed the peak responsivity at 330 nm and the ultraviolet-visible rejection ratio (R330 nm/R400 nm) is more than four orders of magnitude at 3 V bias. For the device with 2 m finger pitch the detectivity was calculated as 4.21011 cm Hz 1/2/W at 330 nm. Furthermore the transient response measurement for all devices revealed similar rise time of 10 ns. The 90%-10% fall times are 130 ns 170 ns and 230 ns for the devices with different finger pitches of 2 m 5 m and 10 m respectively..
