In its late stage, Alzheimer's disease results in progressive muscle weakness in the arms and legs. The aim of this study was to determine whether mice expressing the skeletal muscle-specific mutant PS2 gene (a model of Alzheimer's disease) are a useful experimental system to study the protective effect of exercise on A beta-42 reduction, improvement of behavioural function and changes in metabolic parameters. With this aim in mind, the transgenic mice were subjected to treadmill exercise for 3 months. The results showed that in transgenic mice, but not in normal mice, treadmill exercise resulted in a reduction of A beta-42 deposits and an improvement in behavioural function, thereby restoring normal concentrations of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and triglyceride. Thus, exercise may represent a practical therapeutic strategy for use with human patients with Alzheimer's disease. 相似文献

Predicting Employee Turnover from Friendship Networks 总被引:1,自引:0,他引:1

Employees (n=40) at a fast-food restaurant were surveyed about characteristics of their position and their level of satisfaction. Employees were then asked to report with whom they regularly communicated inside and outside the workplace and to indicate how close they were to employees with whom they were linked. Employee turnover was measured after three months had elapsed. A goal of the research was to replicate a model of employee turnover that predicts employees more central in their social network to be less likely to leave, and to test a social support explanation of the centrality model. The results indicated that employees who reported a greater number of out-degree links with friends were less likely to leave. The number of in-degree links with friends did not significantly predict turnover, and neither did network links with peers. Friendship prestige, measured by the number of in-degree links, was strongly correlated with relational closeness and amount of time spent with employees outside the workplace. 相似文献

The increased number of international students in United States universities and colleges have created the need for the development of services that appropriately reflect their needs and characteristics. The Career Center at the University of Missouri, Columbia reacted to this phenomenon by developing career services exclusively for international students. Career services are provided as individual services and online services, and consist of information on graduate schools and entrance examination practices, information on available employment opportunities and work permit policies, career assessments, and information about specific skills for obtaining a job in the United States. Several marketing strategies were used to ensure international students' use of services. Important points in developing career services for international students are presented. 相似文献

Technological pedagogical content knowledge TPACK refers to the knowledge set that teachers currently use to further improve the quality of their teaching and assist their students in learning. Several TPACK models have been proposed, either for discussing TPACK's possible composition or its practical applications. Considering that teachers' practical experiences should also be critical to the development of those teachers' knowledge, this study invited a research panel (six researchers) and an expert panel (54 science‐related educators) to propose and validate the framework of TPACK‐practical. After two rounds of anonymous communications that followed Delphi survey techniques, a total of eight dimensions of TPACK‐practical and corresponding indicators were identified and rated as having high levels of importance. Among these knowledge dimensions, the knowledge of direct information and communication technology uses for enhancing teachers' professionalism and students' conceptual comprehension was rated with a high level of importance. Also, disciplinary differences were found to exist between the different groups of experts. Biology teachers showed significantly higher ratings across all knowledge dimensions, whereas physics teachers' ratings were comparatively low. Such findings suggest that the structure and content of subject matter shapes not only the way they teach with technology but also the thinking logics they build longitudinally from their learning experiences. 相似文献
