Correlativity study between expression of DNA double-strand break repair protein and radiosensitivity of tumor cells

Liang ZHUANG, Shiying YU, Xiaoyuan HUANG, Yang CAO, Huihua XIONG

《医学前沿（英文）》 2009年第3卷第1期页码 26-29 doi: 10.1007/s11684-009-0008-7

摘要： DNA double-strand break (DSB) is generally regarded as the most lethal of all DNA lesions after radiation. Ku80, DNA-PK catalytic subunit (DNA-PKcs) and ataxia telangiectasia mutated (ATM) proteins are major DSB repair proteins. In this study, survival fraction at 2Gy (SF2) values of eight human tumor cell lines (including four human cervical carcinoma cell lines HeLa, SiHa, C33A, Caski, three human breast carcinoma cell lines MCF-7, MDA-MB-231, MDA-MB-453, and one human lung carcinoma cell line A549) were acquired by clone formation assay, and western blot was applied to detect the expressions of Ku80, DNA-PKcs and ATM protein. The correlativity of protein expression with SF2 value was analyzed by Pearson linear correlation analysis. We found that the expression of same protein in different cell lines and the expression of three proteins in the same cell line had a significant difference. The SF2 values were also different in eight tumor cell lines and there was a positive correlativity between the expression of DNA-PKcs and SF2 ( ＝0.723, = 0.043), but Ku80 and ATM expression had no correlation with SF2 ( >0.05). These findings suggest that the expression level of DNA-PKcs protein can be an indicator for predicting the radiosensitivity of tumor cells.

Optimal Su-Do-Ku based interconnection scheme for increased power output from PV array under partial

P. SRINIVASA RAO,P. DINESH,G. SARAVANA ILANGO,C. NAGAMANI

摘要： Partial shading is a common phenomenon in PV arrays. They drastically reduce the power output because of mismatch losses, which are reliant on the shape of the shade as well as the locations of shaded panels in the array. The power output can be improved by distributing the shade over various rows to maximize the current entering the node. A Su-Do-Ku configuration can be used to rearrange the physical locations of the PV modules in a total cross tied PV array with the electrical connections left unchanged. However, this arrangement increases the length of the wire required to interconnect the panels thus increasing the line losses. In this paper, an improved Su-Do-Ku arrangement that reduces the length of the wire required for the connection is proposed. The system is designed and simulated in a Matlab/Simulink environment for various shading patterns and the efficacies of various arrangements are compared. The results prove that the power output is higher in the proposed improved Su-Do-Ku reconfiguration technique compared to the earlier proposed Su-Do-Ku technique.

Selective reduction of NO by photo-SCR with ammonia in an annular fixed-film photoreactor

YiangChen CHOU, Young KU

《环境科学与工程前沿（英文）》 2012年第6卷第2期页码 149-155 doi: 10.1007/s11783-010-0296-9

摘要： Gaseous NO was photocatalytically reduced at room temperature by photo-assisted selective catalytic reduction (photo-SCR) with ammonia over TiO in this study. NO reduction efficiency and N selectivity were determined from gases composition at the outlet stream of photoreactor. Effect of operating conditions, e.g. light intensity and inlet concentrations of ammonia and oxygen, on the NO reduction efficiency and N selectivity were discussed to determine the feasible operating condition for photocatalytic reduction of NO. Experimental results showed that selective catalytic reduction of NO with ammonia over TiO in the presence of oxygen was a spontaneous reaction in dark. The photoirradiation on the TiO surface caused remarkable photocatalytic reduction of NO to form N , NO , and N O under 254 nm UV illuminations, while almost 90% of N selectivity was achieved in this study. The ammonia and oxygen molecules played the roles of reductant and oxidant for NO reduction and active sites regeneration, respectively. The reduction of NO was found to be increased with the increase of inlet ammonia and oxygen concentrations until specific concentrations because of the limited active sites on the surface of TiO . The kinetic model proposed in this study can be used to reasonably describe the reaction mechanism of photo-SCR.

Impact of “ultra low emission” technology of coal-fired power on PM

摘要： In response to severe haze pollution, the Chinese government has announced a series of policies focusing on controlling emissions from coal consumption. “Ultra-low emission” (ULE) technologies have the potential to dramatically reduce emissions from coal-fired power plants, and have been deployed at some facilities in recent years. This paper estimated the potential environmental benefits of the widespread adoption of ULE in the Jing-Jin-Ji Region. Atmospheric modeling scenarios were analyzed for three cases: a “standard” scenario assuming no ULE deployment, a “best case” scenario assuming complete adoption of ULE across all power plants in the region, and a “natural gas” scenario, assuming emissions factors consistent with natural gas-fired power generation. The simulations show that the widespread adoption of ULE technologies can be an effective and economically competitive option for reducing the impacts of coal-fired power generation on air quality.

基于区域化高斯过程地图重构的新型三维点集配准方法 Research

摘要：点集配准问题是移动智能无人系统领域一项重要研究课题。本文提出一种全新“帧到地图”式三维点集配准方法。首先提出区域化高斯过程（Gaussian process，简称GP）地图重构算法，由此得到一种全新地图表现形式。将由GP得到的预测值和预测位置组合在一起作为预测点，以此自然地建立起预测点对的对应关系，并使用迭代方式计算位姿变换。利用3组标准点集数据集对该方法进行验证和测试。实验结果表明，相较于迭代最近点算法和正态分布变换两种经典点集配准方法，该方法在精度和效率两方面都有更佳表现。此外，所提的地图重构算法能够在降低内存消耗的同时，提供稠密的类点云地图。

摘要：本文在分析农业发展形势的基础上认为，为了保障国家粮食安全，农业应通过内部分工来大幅提升劳动生产率；养殖业应向规模化、现代化转变，种植业需向“二八格局”转变（即20% 的大农生产80%的农产品并贡献20% 的增加值、80% 的小农生产20% 的农产品并贡献80% 的增加值），大农主要生产粮食等大宗农产品以保障粮食安全，小农主要发展高值农业以保障收入增长。
