药品侵权责任研究

药品缺陷是承担药品侵权责任的核心,药品缺陷认定标准应当将处方药与非处方药予以区分,处方药缺陷判断标准可以是以医师的预期为基础,兼进行药品成本效益分析;而非处方药判别标准可以采用消费者期待标准。医疗机构不应视为药品销售者承担严格责任。

高住低训中EPO变化规律的研究

血清EPO(erythropoietin，促红细胞生成素)与红细胞的生成有密切关系。为确切了解EPO在高住低训中的变化规律，将14名大学生分为高住低训组和低住低训组，每组7人。高住低训组每天低压低氧(2500m模拟高度)暴露12小时；低住低训组在实验期间不进行低氧暴露。两组每天在常压常氧环境下进行一次3000m跑训练。实验为期4周。结果表明，促红细胞生成素在间断性低氧暴露初期就有升高变化，1天后出现高峰，这一高EPO水平一直维持到低压氧暴露结束。另外，对第2次低氧暴露完当天出低压氧仓即刻与常氧暴露10h后所测EPO结果的比较表明，常氧暴露后EPO呈下降趋势，说明间断性低氧暴露对EPO生成存在着慢性积累的过程。低住低训组的EPO水平一直比较平稳，说明常氧环境对EPO的分泌无明显影响。     

Applying user analytics to uses and effects of social media in China

ABSTRACT

We introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content.     

The influence of childhood polyvictimization on disordered eating symptoms in emerging adulthood

Children who endure multiple victimization experiences, or “polyvictims," are vulnerable to maladaptive outcomes. Yet, little research exists evaluating the relationship between childhood polyvictimization and disordered eating symptoms (DES) in emerging adulthood. The current study examines the relationship between childhood polyvictimization and DES in emerging adults. Data were collected from 288 participants across two universities using online self-report measures. Hierarchical regression analyses revealed a significant positive relationship between number of childhood victimization experiences and DES in young adulthood (ß = 0.14; p = 0.016). Female participants were more likely to demonstrate DES (ß = 0.14; p = 0.008). Further, high levels of emotion dysregulation during young adulthood were associated with more DES (ß = 0.33; p < 0.001). Findings suggest that exposure to victimization experiences in childhood increases individuals’ risk for exhibiting DES in young adulthood. Results also highlight the strong relationship between individuals’ emotion regulation abilities and the presence of DES. Findings align with the theory that children who have endured high levels of victimization often feel overwhelmed by their emotions and circumstances, demonstrate emotion regulation difficulties, and may rely on maladaptive coping strategies, including disordered eating, to manage adversities. Study results emphasize the importance of considering victimization history when working with emerging adults displaying disordered eating symptomatology.

Effect of thiazide drug compound on the testicular protein and cholesterol contents of albino rat

In this study the effect of thiazide diuretic compound on the protein and cholesterol contents in the testes of albino rats as the experimental model. The drug thiazide was administered orally daily for 10,20 and 30 days at the dose of 100mg/kg body weight. Total protein decrease in the testes of rats were evidenced may be due to the side effects of thiazide drug compound which is linked with the hyponatremia and protein metabolism. An elevated level of cholesterol contents observed in thiazide treated rats also revealed that the side effect of drug compound thiazide and also may be due to the stimulation of catecholamine which is stimulated therefore, the biochemical estimation such as protein and cholesterol in the testes after the thiazide treatment determined the effectiveness of diuretic drug compound would provide clinical evidences of their side effects.     

Understanding Greek Primary School Children's Comprehension of Sun Exposure

The purpose of this study was to assess Greek primary (1st to 6th grade) school children's understanding of sun exposure during summer vacation. Our results show that children know the damaging effects of long time exposure and the precautions that should be taken during sun bathing (sun glasses, hat, umbrella, sunscreen, etc). Nevertheless, they do not seem to avoid being exposed between 12.00 A.M. and 15.00 P.M., which is the most dangerous time. The socioeconomic status of father has no effect on the attitude of children towards taking protection measures when exposed to the sun, however, the educational status of the mother appears to influence children's reported knowledge and behaviour. Place of residence (urban or rural areas) and gender does not influence their knowledge on the sun's damaging effects and the precautions they should take. Finally, as children grow older they seem to gradually reduce the protective measures they take.     

Effect of lead exposure on the immune function of lymphocytes and erythrocytes in preschool children

INTRODUCTION Over the past few years, systematic studies onthe effect of lead exposure on the human body haveled to an understanding that lead is neurotoxic andhas adverse effect on the immune system. So far,however, research on the immunotoxic effects oflead has been limited to animal experiments andpeople with occupational exposure to lead (Shen etal., 1996; Mishra et al., 2003; Liu et al., 2000).Presently, there are no reports on the influence oflead exposure on lymphocyte and …
