p16INK4a基因对NIH3T3细胞衰老影响的研究

p16^INK4a是细胞周期负调控因子，在多种细胞的衰老过程中起着关键作用．为了研究p16^INK4a的表达对小鼠成纤维细胞即NIH3T3细胞生长增殖的影响，将真核表达载体PRetro-onpl6通过逆转录病毒介导的方法将其转染至NIH3T3细胞中，经嘌呤霉素筛选，获得整合有p16基因的稳定细胞株NIH3T3／pRetro-on-p16，并通过脱氧四环素的诱导，观察到NIH3T3／pRetro-on-p16衰老的显著特征：细胞宽大铺展、形状不规则、折射率低等，并且细胞生长速度明显减慢．     

The 1983 C.H. McCloy Research Lecture Appetite and Body Composition Consequent to Physical Activity

Abstract

Body composition has become a major field of interest for many exercise and sport scientists as well as clinicians who specialize in the prevention of and rehabilitation from hypokinetic diseases. This review article discusses the state of the art within selected areas of body composition, including the following: exercise in appetite regulation, the use of body density to estimate relative body fat in selected populations, the use of anthropometric equations to estimate body composition, and alterations in body composition with exercise training. It was concluded that acute bouts of exercise may have short term anorexigenic effects, but that alterations in appetite with extended periods of training are less clearly defined. Exercise training does result in modest decreases in total and fat weight and in relative body fat, and small increases in lean body weight. However, these alterations are not substantial. Finally, major research efforts are needed to improve methodology in body composition assessment.     

论我国物权变动模式的选择

物权变动是物权法的核心问题，其中，我国的物权变动模式应如何选择更是讨论的焦点。因为这一选择的过程，是以一系列理论难题的解决为前提的，即我国要不要承认物权行为，是否应当承认物权行为的独立性和无因性，登记和交付这样的公示行为是物权变动的对抗要件还是成立要件等。通过对现有的三种模式进行比较，对以上理论难点逐一分析得出适合我国的物权变动模式。

中国传统译论评述

传统译论是现代译论转化的基础,因此有必要在构建我国现代译论的过程中对我国传统译论进行一次有益的评述,进而更好地为我国的现代译论建设服务。本文针对我国传统译论中一些固有的特点进行分析并就这些特点与西方译论进行对比,试图分析各中原因,以期实现对传统译论的批判性继承。     

Antimicrobial activity ofTerminalia bellerica

The antimicrobial activity of crude and methanol extract ofTerminalia bellerica dry fruit was tested by disc diffusion method, against 9 human microbial pathogens. Crude aqueous extract of dry fruit at 4 mg concentration showed zone of inhibition ranging from 15.5–28.0 mm.S. aureus was found to be highly susceptible forming highest zone of inhibition, suggesting thatT. bellerica was strongly inhibitory towards this organism. These pathogens were highly sensitive to the methanol extract forming 14.0 to 30.0 mm zone of inhibition suggesting that the methanol extract ofT. bellerica was more effective than crude extract against most of the microbes tested exceptE. coli (enteropathogen) andP. aeruginosa. The minimal inhibitory concentrations (MICs) of crude and methanol extracts were determined by broth dilution technique which ranged from 300 to >2400 μg/ml and 250 μg to >2000 μg/ml respectively, indicating thatT. bellerica was highly effective againstS. aureus with lower MIC values. There were some biochemical alterations induced byT. bellerica. These results indicate thatT. bellerica dry fruit possesses potential broad spectrum antimicrobial activity.     

略论传统中国译论的形态缺憾及其现代转换

对中国传统译论的探讨由来已久,但多拘泥于方法论而很少对其进行总体上的把握和分析。因而科学界定中国传统译论、分析其形态缺憾并探索其现代转换的路径对建立中国翻译理论的学科体系有着积极的意义。     

Acute effects of two different tennis sessions on dorsal and lumbar spine of adult players

The aim of the study was to evaluate the dorsal and lumbar spine of expert and recreational tennis players before (pre) and after (post) two different training sessions. The sample consisted of 17 male tennis players, nine expert and eight recreational males (age 21.2 ± 1.6 years). We assessed the back surface by rasterstereography pre and post two different training sessions both lasting 1.5 h: a standard training and a specific over-shoulder shots training session, respectively. Lordotic and kyphotic angle, length, imbalance, inclination for trunk, pelvic torsion, left and right lateral deviation and surface rotation were measured. Tennis expertise (expert versus recreational) significantly affected the surface rotation and right lateral deviation (P < 0.05). Trunk length was affected by intervention (pre versus post) (P < 0.05). Left lateral deviation differed both for type of session (session 1 versus session 2) and intervention (P < 0.001, P < 0.05). Expert tennis players had higher values on surface rotation and right lateral deviation, around or just above physiological values (0–5° and 0–5 mm, respectively). Type of session significantly affected left lateral deviation, indicating that over-shoulder shots lead to a higher stress for the spine; the workload produced by both single sessions led to a shortening effect on trunk length. A single training session can induce acute modifications in some parameters of dorsal and lumbar spine of players.
