Promoting Exercise Self-Efficacy With an Exergame

A new generation of exercise video games (exergames) shows promise as a tool to motivate and engage users in physical activity. However, little research has been conducted to examine whether exergames work equally well across diverse populations and contexts. Therefore, in the present study, the authors investigated the effects of an individual psychological difference factor and a specific contextual factor on the exercise experience using an exergame. They used the objective self-awareness theory as the theoretical underpinning. In a 2 (seeing the image of self on screen: seeing oneself vs. not seeing oneself) × 2 (body image dissatisfaction: low vs. high) between-subjects design experiment, the authors found significant interaction effects showing that the feature of seeing the image of self on screen provided by the exergame works positively for individuals with low body image dissatisfaction, yet works negatively for individuals with high body image dissatisfaction. The finding of the present study has significant implications for health professionals and individuals who use the new generation of exergames for physical activities.     

Detraditionalisation and attitudes to sex outside marriage in China

China has undergone massive socio-economic change over the past 30 years. In parallel, there have been huge changes in social and sexual mores. Until the end of the Mao era strict norms prevailed, with sex outside marriage widely regarded as immoral and unacceptable. Detraditionalisation theory describes the abandonment or reconfiguration of the socio-cultural traditions and has been explored widely in Western settings. This study aimed to explore its relevance for China through exploring attitudes towards premarital sex, extramarital sex, same-sex relations and sex work. We conducted semi-structured interviews with 212 men and women aged 18 to 39 in urban and rural areas of three provinces: Zhejiang, Guizhou and Yunnan. Analysis identified emerging themes. Results show varying degrees of acceptance of the four sexual behaviours, with premarital sex seen as common, homosexuality still regarded as unacceptable by the majority but considerable acceptance of commercial sex work as part of male business transactions and social life. China appears to be on a pathway of detraditionalisation with specific Chinese features. This study suggests that the concept of detraditionalisation applies well to non-Western contexts, but the path it takes is culture-specific and relatively unpredictable.     

Bioaccumulation of PBDE congener 2,2′,4,4′-tetrabromodiphenyl ether by Heterosigma akashiwo in response to different nutrient concentrations

Changes in the bioaccumulation of 2,2′,4,4′-tetrabromodiphenyl ether (BDE-47) in the marine alga Heterosigma akashiwo (Raphidophyceae) were examined for different concentrations of nitrate (0, 128, and 512 μmol dm^?3) and phosphate (0, 8, and 32 μmol dm^?3) in the semi-continuous culture with 20% renewal rate. The BDE-47 content per cell and per culture, as well as the accumulated percentage of available BDE-47, presented a significant decreasing trend with the increase in nitrate and phosphate concentrations. The N-0 (4.0 × 10^?6 ng cell^?1) and P-0 (5.8 × 10^?6 ng cell^?1) treatments had significantly higher BDE-47 content per cell than other treatments. In comparison, the difference in BDE-47 per algal culture and accumulated percentage between the nitrate treatments or phosphate treatments was not as obvious as the BDE-47 content per cell. BDE-47 per cell presented significantly negative correlation with nitrate and phosphate concentrations, and the accumulated BDE-47 was in positive correlation with lipid content. log BAF_lip for BDE-47 in H. akashiwo ranged from 6.70 to 7.25. The results of this study indicate that variation in BDE-47 accumulation by H. akashiwo corresponds to the change in cellular lipid content induced by different nitrate and phosphate concentrations.

Multimodality noninvasive cardiac imaging established the diagnosis of aneurysms of Vieussens’ arterial ring

Noninvasive cardiac imagines are rapidly evolving in recent years. In this patient with Vieussens’ arterial ring aneurysm, multimodality noninvasive cardiac imaging provided sufficient information for diagnosis and surgical decision making. This report no only provides unique information leading to better understanding on aneurysms of Vieussens’ arterial ring, but also highlights the important role of multimodality noninvasive cardiac imagines in the diagnosis and management of certain cardiac emergencies.     

原核表达重组人白介素-3及其对脐带血造血干细胞体外增殖的影响

目的研究原核表达重组人白介素-3(rhIL-3)及其对脐带血造血干细胞体外增殖的影响。方法构建pET-43.1-rhIL-3表达载体,克隆至BL21菌株,并进行中试发酵生产,所得包涵体经透析复性后,采用阳离子交换柱纯化,纯化产物送N-端测序。Ficoll密度梯度离心结合免疫磁珠法富集人脐带血中CD34+细胞,以不同浓度rhIL-3及干细胞因子(SCF)、Fms样酪氨酸激酶受体-3配体(FL)和促血小板生成素(TPO)因子组合培养1周,测定细胞总数,计算CD34+细胞增殖倍数。结果在SCF和FL存在下,rhIL-3可明显促进造血干祖细胞增殖,但较无rhIL-3时CD34+细胞占细胞总数的比例有所下降。与SCF、FL共同作用时的最佳浓度在15 ng/mL左右,与SCF、FL、TPO共同作用时的最佳浓度在50 ng/mL左右。结论高效表达及纯化的rhIL-3与SCF、FL和TPO细胞因子组合对脐带血造血干细胞具有良好的增殖作用。
