Short-term reliability of inflammatory mediators and response to exercise in the heat

Prospective application of serum cytokines, lipopolysaccharide (LPS), and heat shock proteins (eHSPs) requires reliable measurement of these biomarkers that can signify exercise-induced heat stress in hot conditions. To accomplish this, both short-term (7 day) reliability (at rest, n = 12) and the acute responsiveness of each biomarker to exercise in the heat (pre and post 60-min cycling, 34.5°C and 70% RH, n = 20) were evaluated. Serum was analysed for the concentration of C-reactive protein (CRP), interleukin-6 (IL-6), heat shock protein 72 (eHSP72), immunoglobulin M (IgM) and LPS. Test–retest reliability was determined as the coefficient of variation (CV). Biomarkers with the least short-term within-participant variation were IL-6 (19%, ±20%; CV, ±95% confidence limits (CL)) and LPS (23%, ±13%). Greater variability was observed for IgM, eHSP72 and CRP (CV range 28–38%). IL-6 exhibited the largest increase in response to acute exercise (95%, ±11%, P = < 0.001) and although CRP had a modest CV (12%, ±7%), it increased substantially post-exercise (P = 0.02, ES; 0.78). In contrast, eHSP72 and LPS exhibited trivial changes post-exercise. It appears variation of common inflammatory markers after exercise in the heat is not always discernible from short-term (weekly) variation.     

Lost and Found: Making Sense of Foreign Spaces and the Self with Public Transport

How does public transport both enable and restrict one’s negotiation and interaction with cultural, social and material landscapes? The understanding of social space and self is guided by one’s journey through those spaces, by witnessing events and public conduct. This article presents autoethnographic accounts of two communication studies researchers placed in Cape Town, South Africa, and Helsinki, Finland, for more than three months. In both situations, researchers relied on public transport with which they were unfamiliar. This study considers how those experiences were perceived, and how the researchers encountered and experienced the new social environments, local population and themselves.     

热休克蛋白70及运动对衰老的影响研究

衰老的机制到目前为止没有确切的理论解释,许多研究表明衰老与HSP70的关系密切.论文对HSP70与衰老之间的相互影响及其机制等方面进行了综述,并着重探讨了运动诱导的HSP70对衰老机体的作用,以期为运动延缓衰老提供有力的理论依据.     

文化震荡背景下信仰缺失的心理学透视

在文化震荡背景下,计划经济向市场经济转型引发的价值观矛盾,西方国家信仰危机的影响,以及封建迷信思想和非法邪教组织的迷惑等,必然会导致个体显性价值观的矛盾、迷惘和隐性民族文化心理的冲突、失衡,进而形成信仰缺失.信仰缺失不但会使人心理失衡、行为失范,而且会影响社会的和谐与稳定.因此,只有依据新的历史条件适时进行信仰重建,才能为个体的心理健康与社会的和谐发展提供可靠的思想基础和有力的精神保障.     

HSP70和肝脏抗氧化能力

热休克蛋白是生物体在不利环境因素刺激下应激合成的一组特殊的蛋白质.实验表明,经过预应激处理后,生物机体对再次热休克或其它应激刺激产生耐受;而其它应激刺激作用于机体后,亦使其获得对热休克的耐受.因此,在对相关研究综述的基础上,提出通过HSP70途径来提高肝脏抗氧化能力,避免或减小大强度运动对肝脏的损伤.     

骨骼肌热休克蛋白变化研究进展

在应激状态,细胞快速合成一组新的蛋白质,称为热休克蛋白.研究表明,骨骼肌含有多种热休克蛋白.热休克蛋白随肌纤维类型不同而有不同的表达,表明热休克蛋白表达具有肌纤维类型特异性.骨骼肌疾病和运动都能诱导热休克蛋白表达增强,然而热休克蛋白在骨骼肌内的诱导、调节的分子机制和它在维持骨骼肌功能方面的作用还没有被完全理解.对骨骼肌热休克蛋白在生理和病理情况下的改变进行综述.

AtHsfAla 对拟南芥幼苗在干旱中生理指标的影响

以过量表达 AtHsfAla 及 AtHsfAla 基因沉默的转基因植株为材料,通过控制土壤水分进行干旱处理,结果显示,过量表达型干旱处理后的存活率最大,而基因沉默型最小,表明 AtHsfA1a 能增强植物的抗旱性。为了从生理水平研究 AtHsfA1a 提高抗旱性的机制,研究发现过量表达型的叶片相对含水量和叶绿素含量最高,而沉默型最低。不同基因型植株的 H2 O2和 MDA 的含量正好相反,说明 AtHsfA1a 通过保护细胞膜而减小细胞所受氧化伤害来提高抗旱能力。
