Prestin is the motor protein of cochlear outer hair cells （OHCs）. It is able to perform rapid and reciprocal electromechanical conversion that underlies OHC electromotility. Due to the inadequate size of a single prestin molecule to form the2.nm intramembraneous protein particles （IMPs） in the OHC lateral membrane （LM）, the possibility of prestin oligomerization has been proposed. It has been suggested that prestin molecules form highorder oligomers, most likely as the tetramer, in heterologous systems. In OHCs, however, the oligomeric structure of prestin remains unclear. Here we calculated the prestin-related charge density in both gerbil and guinea pig OHCs through measuring their nonlinear capacitance （NLC） and LM surface area, showing that the average charge density （2., 608 μm-2.in gerbils; 19, 460 μm-2.in guinea pigs） is statistically 4 times the average density of IMPs （5,686 μm-2.in gerbils; 5, 000 μm-2.in guinea pigs）. This suggests that each IMP contains four prestin molecules based upon the notion that each prestin transfers a single elementary charge, implying that prestin forms tetramers in OHCs. To determine whether the prestin tetramer functions as a mechanical unit, we subsequently compared the slope factors （α） of electromotility and NLC simultaneously measured from the same OHC, showing that the α values of the two are statistically the same. This suggests that each prestin molecule in the tetramer is mechanically independent and equally contributes to OHC electromotility.

原核生物操纵子结构的准确注释对基因功能和基因调控网络的研究具有重要意义,通过生物信息学方法计算预测是当前基因组操纵子结构注释的最主要来源.当前的预测算法大都需要实验确认的操纵子作为训练集,但实验确认的操纵子数据的缺乏一直成为发展算法的瓶颈.基于对操纵子结构的认识,从基因间距离、转录翻译相关的调控信号以及COG功能注释等特征出发,建立了描述操纵子复杂结构的概率模型,并提出了不依赖于特定物种操纵子数据作为训练集的迭代自学习算法.通过对实验验证的操纵子数据集的测试比较,结果表明算法对于预测操纵子结构非常有效.在不依赖于任何已知操纵子信息的情况下,算法在总体预测水平上超过了目前最好的操纵子预测方法,而且这种自学习的预测算法要优于依赖特定物种进行训练的算法.这些特点使得该算法能够适用于新测序的物种,有别于当前常用的操纵子预测方法.对细菌和古细菌的基因组进行大规模比较分析,进一步提高了对基因组操纵子结构的普遍特征和物种特异性的认识.

作者： Xi Tingfei Huang Nan Tian Wenhua Yang Ping Leng Yongxiang Cheng Xiang Liu Xianghuai(1 ) center of Medical Device, National Institute for Control of Pharmaceotical and Biological Products, beijing, 100050,{2.2. Department of Materials engineering,

A TioO2.x/TiN multilayer film was synthesized by ion beam enhanced deposition to modify the properties of material for artificial heart valve (AHV). The blood compatibility of the film was evaluated by clotting time measurement, platelet adhesion test, hemolysis analysis and protein adsorption experiment. The investigation on mechanical properties including fatigue life, wear resistance and adhesion strength between AHV material matrix and the film were carried out. the results revealed a significant improvement of blood compatibility of AHV material by the film coating, and the high level of mechanical properties have also been demonstrated. The synthesized film shows a promising of more desirable AHV material.
