Journal of Sport and Health Science 2016年第2期5卷 155-158页

作者： zhengtang Qi Shuzhe Ding The Key Laboratory of Adolescent Health Assessment and Exercise Intervention (East China Normal University) Ministry of Education School of Physical Education and Health East China Normal University

The concept that ＂Exercise is Medicine＂ has been challenged by the rising prevalence of non-communicable chronic diseases （NCDs）. This is partly due to the fact that the underlying mechanisms of how exercise influences energy homeostasis and counteracts high-fat diets and physical inactivity is complex and remains relatively poorly understood on a molecular level. In addition to genetic polymorphisms in humans that lead to gross variations in responsiveness to exercise, adaptation in mitochondrial networks is central to physical activity, inactivity, and diet. To harness the benefits of exercise for NCDs, much work still needs to be done to improve health effectively on a societal level such as developing personalized exercise interventions aided by advances in high-throughput genomics, proteomics, and metabolomics. We propose that understanding the mitochondrial phenotype according to the molecular information of genotypes, lifestyles, and exercise responsiveness in individuals will optimize exercise effects for prevention of NCDs.

为保护白鹤滩水电站建设范围内国家二级保护野生植物红椿,采用抢救性移栽方法,移栽野生红椿1 513株,移栽后成活率达94.5%,2.后保存率90.9%。对抢救性移栽结果进行分析,认为在移栽地选择适宜、采用技术得当的情况下,影响红椿抢救性移栽成败的关键因素中,起挖和栽植间隔时间影响最大,其次是土球保留完整程度,再次是树体的损伤程度。移栽成活后,管护是影响保存的关键,尤其是牲畜破坏和人为破坏造成的影响往往是不可逆的。

Significant changes in the Raman spectrum of single-layer graphene grown on a copper film were observed after the spontaneous oxidation of the underlying substrate that occurred under ambient conditions. The frequencies of the graphene G and 2. Raman modes were found to undergo red shifts, while the intensities of the two bands change by more than an order of magnitude. To understand the origin of these effects, we further characterized the samples by scanning tunneling microscopy （STM）, scanning tunneling spectroscopy （STS）, and atomic force microscopy （AFM）. The oxidation of the substrate produced an appreciable corrugation in the substrate without disrupting the crystalline order of the graphene overlayer and/or changing the carrier doping level. We explain the red shifts of the Raman frequencies in terms of tensile strain induced by corrugation of the graphene layer. The changes in Raman intensity with oxidation arise from the influence of the thin cuprous oxide film on the efficiency of light coupling with the graphene layer in the Raman scattering process.
