摘要： 杂技艺术，是一门综合性形体表演艺术，它涉及到运动生理学、运动训练学、力学、心理学等诸门学科。杂技艺术要振兴，要发展，就要培养训练出既有过硬的杂技技巧，又能尽快出节目（缩短杂技节目周期）的新一代杂技演员，就必须从学员抓起，还必须以科学的训练方法进行教学。因此，对杂技学员的基本功和节目功的洲练以及对教与学心理生理素质等诸方面作较系统的分析、研究，是杂技界应该重视和值得探索的课题。

摘要： 人体生理学实验教学的改革,打破了过去以验证性的、单一性实验为主的单科分割式教学模式,除增加与病理生理学、药理学联系的综合性、设计性实验课外,设计出"基础性、综合性、设计性实验"3步走的科学实验教学过程。通过生理实验教学内容的改革,培养了学生实践能力和创新精神,提高了医学实验教学质量。

关键词： 运动生理学   南非足球世界杯   内稳态  

摘要： 从内稳态的角度讨论了海拔、纬度、队服颜色、年龄和体形等因素对比赛结果的影响。研究认为球员的运动水平由足球运动特异的内稳态(football-specific homeostasis,FbSH)来维持。FbSH可以抵抗小的干扰,但会被应激所打破。处于应激内稳态(stress-specific homeostasis,StSH)的应激可以将FbSH1成功转化为FbSH2,但同时出现的多种应激不可能各自处于StSH,只能打破FbSH,导致比赛成绩下降。足球世界杯比赛中,参赛国家和东道主国家的纬度差异可以形成阳光应激。阳光应激越大,输球的可能性越大。

摘要： Opinion statement: Fractional flow reserve (FFR) is an invasive pressure-derived index of epicardial stenosis severity used in the catheterization laboratory to assess the hemodynamic significance of coronary lesions when non-invasive functional assessment has either not been performed or is inconclusive. The rationale for the use of FFR is that coronary angiography cannot accurately predict the hemodynamic significance of lesions with diameter stenosis <90% and that there is a large body of literature supporting the use of FFR for directing coronary revascularization. Specifically, in patients with stable angina and low-risk acute coronary syndromes, revascularization with either percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery should be deferred for epicardial coronary stenoses with an FFR>0.80. Use of FFR to direct coronary revascularization should continue to increase as it has been demonstrated to improve outcomes and reduce cost. © 2010 Springer Science+Business Media, LLC.

摘要： Mammalian cells are sensitive to extracellular microenvironments. In order to faithfully explore the physiological responses of cells to extracellular conditions, a steady, homogenous, and three-dimensional (3-D) culture environment is required because it can provide a more quantifiable and biologically-relevant culture condition. To achieve this, this study reports a perfusion micro cell culture platform encompassing 22 microbioreactor units for high throughput 3-D cell culture. The cell culture platform structurally consisting of a plug and a microbioreactor chamber module was simply fabricated by replica molding of polydimethylsiloxane (PDMS) polymer. The platform features in the proposed plug module with multiple molds incorporated, facilitating the preparation of cell encapsulated 3-D hydrogel constructs in a precise and efficient manner. This trait is found particularly useful for high-precision and high-throughput micro 3-D cell culture-based assay. In this study, the real value of the proposed platform to maintain a stable and homogenous culture condition was discussed. Besides, the application of the presented platform for precisely investigating the effect of serum concentration on the metabolic activities and biosynthetic abilities of articular chondrocytes was also demonstrated. As a whole, the proposed device has paved an alternative route to carry out high throughput micro-scale 3-D perfusion cell culture in a simple, cost-effective and precise manner. The promising applications include 3-D cell culture-based high throughput drug or toxicity testing/screening, or other investigations on the cell biology, where the precise quantification of the links between the cellular responses and extracellular conditions is required.

摘要： Various behavioural and physiological tests were applied to determine whether an aluminised modified zeolite clay product (Z2G1), used to cap phosphorus release from lake sediments, had sub-lethal effects on adult freshwater crayfish (Paranephrops planifrons). In situ exposures of caged crayfish before and after application of modified zeolite to Lake Okaro, Central North Island, New Zealand, at a nominal application concentration of 350 g m(-2), did not impact the survival of freshwater crayfish or produce any significant sub-lethal effects on crayfish mobility or physiology that we could detect. In laboratory sediment tests, crayfish did not show any consistent effect from short-term (10 days) exposure to modified zeolite (at concentrations of 350, 700 or 2,100 g m(-2)) or to alum. When combined, the field and laboratory data provide strong evidence that applications of 350 g m(-2) modified zeolite will have no short-term effect on adult crayfish, with a 'margin of safety' for higher application rates. Chronic exposure effects of capping agents and the indirect impacts of lake treatment (e.g. food web responses) are yet to be determined. Quantitative measures of shade- and shelter-seeking behaviour, righting behaviour, and length of escape response, could be improved by the addition of standardised behavioural observations. Physiological measures of ammoniacal-N production and oxygen consumption are less variable than behavioural tests, but comparisons between treatments are best conducted simultaneously. A suite of behavioural and physiological sub-lethal measures using field and laboratory exposures is recommended to provide an integrated assessment of crayfish health.
