2Toxic stress,inflammation and symptomatology of chronic complications in diabetes显示文摘Diabetes affects at least 382 million people worldwide and the incidence is expected to reach 592 million by 2035.The incidence of diabetes in youth is skyrocketing as evidenced by a 21% increase in type 1 diabetes and a 30.5% increase in type 2 diabetes in the United States between 2001 and 2009.The effects of toxic stress,the culmination of biological and environmental interactions,on the development of diabetes complications is gaining attention.Stress impacts the hypothalamus-pituitaryadrenal axis and contributes to inflammation,a keybiological contributor to the pathogenesis of diabetes and its associated complications.This review provides an overview of common diabetic complications such as neuropathy,cognitive decline,depression,nephropathy and cardiovascular disease.The review also provides a discussion of the role of inflammation and stress in the development and progression of chronic complications of diabetes,associated symptomatology and importance of early identification of symptoms of depression,fatigue,exercise intolerance and pain.Charles A Downs Melissa Spezia Faulkner 2015World Journal of Diabetes2015,6,4:12
3The influence of biological soil crusts on ^(15)N translocation in soil and vascular plant in a temperate desert of northwestern China显示文摘Aims Desert ecosystems are often characterized by patchy distribution of vascular plants,with biological soil crusts(BSC)covering interplant spaces.However,few studies have comprehensively examined the linkage between BSC and vascular plants through nitrogen(N)or element translocation.the objective of this study was to evaluate the ecological roles of BSC on N translocation from soil to the domi-nant herb Erodium oxyrrhynchum bieb.(geraniaceae)in a temper-ate desert in China.Methods Isotopes(including 15N-glu,15N-NH4Cl and 15N-NaNo3)were used as a tracer to detect translocation of N in two types of desert soil(BSC covered;bare)to the dominant herb E.oxyrrhynchum.three different forms of 15N-enriched N compounds were applied as a point source to small patches of BSC and to bare soil.and we measured isotopes(14N and 15N)and obtained the concentration of labeled-15N in both vascular plants and soils at different distances from substrate application Important Findings Plants of E.oxyrrhynchum growing in BSC-covered plots accumulated moreδ15N than those growing in the bare soil.similarly,soil from b Ccovered plots showed a higher concentration of labeled-N irrespective of form of isotope,than did the bare soil.the concentration of dissolved organic N(15N-glu)in E.oxyrrhynchum was higher than that of dis-solved inorganic N(15N-NH4Cl and 15N-NaNo3).soil covered by BSC also accumulated considerably more dissolved organic N than bare soil,whereas the dominant form of 15N concentrated in bare soil was dissolved inorganic N.Correlation analysis showed that the concentra-tion of labeled-N in plants was positively related to the concentration of labeled-N in soils and the N%recorded in E.oxyrrhynchum.our study supports the hypothesis that BSC facilitates ^(15)N translocation in soils and vascular plants in a temperate desert of northwestern China.WeiWei Zhuang Alison Downing YuanMing Zhang 2015Journal of Plant Ecology2015,8,4:7

5脊柱手法治疗改善运动员本体感觉缺陷机制探讨显示文摘运动员本体感觉缺陷(Proprioception Deficit)与运动损伤、运动表现都有着十分紧密的关系[1-4]。研究显示,运动员全身性本体感觉缺陷的普遍性为63%-92%[5]。近年来,运动员受伤后单关节出现神经肌肉控制水平下降的问题逐渐受到国外研究学者们的高度重视[6-8]。神经肌肉控制的缺失会增加女性膝关节损伤的几率[9]。郑尉 张冰 David Bellin John Downes 李鹏 张展嘉 2016中国运动医学杂志2016,35,1:6
6Recent Advances in the Small Mammal Biostratigraphy and Magnetostratigraphy of Lanzhou Basin显示文摘The consensus view among geologists is that the Lanzhou Basin sequence of sedimentscontains the Oligocene/Miocene boundary, but where this occurs is unknown. Indeed, this is thecrux of the issues concerning mid-Tertiary paleontology in Asia: what fauna corresponds with thistime? What turnover events or distinctive taxa signal the beginning of the Miocene epoch? Onceknown, this will be of broad usefulness because vertebrate-bearing deposits are widespread in Asiaand can be used to date basin sediments. Lanzhou and other basins permit a means of correlating tothe time scale by using fauna and paleomagnetic data locally, and ultimately radiometric data fromdistant localities, to develop a precise biochronology. Herein, we summarize faunal constraints,primarily those of small mammal taxa, on correlation of the Lanzhou magnetozone sequence to themagnetic time scale. We conclude that the lower part of the Xianshuihe Formation contains theOligocene/Miocene boundary, and that the top of the formation, both in the south and north partsof the basin, is middle Miocene in age. Rodents from lower white sand units of the XianshuiheFormation, correlate to the Xiejia assemblage of the Xining Basin, Qinghai Province, and are early,but not earliest, Miocene age. The implication for rodent faunas of the epoch boundary is that theyretained a mainly 'Oligocene' composition, and that other presumed late Oligocene assemblagesmay be, in fact, early Miocene in age. The Lanzhou appearance of Proboscidea is 19-18 Ma, asexpected.LawrenceJ.FLYNN Will DOWNS NeilOPDYKE HUANGKainian Everett LINDSAY 1999Chinese Science Bulletin1999,44,S1:3

8手法治疗改善脊柱功能的作用机制显示文摘脊柱手法治疗(Spinal Manipulation Therapy,SMT)是一种通过双手将快速、小幅度的作用力施加于脊柱上特定部位的治疗手段[1]。脊柱手法治疗是预防、诊断和治疗骨骼肌肉系统相关病症的有效方法之一,在减少肌肉抑制[2]、调节神经肌肉兴奋性[3]、矫正本体感觉缺陷[4]等方面具有一定的临床效果,已得到国外物理治疗师、脊骨神经医生的广泛应用,但在我国应用及相关研究较少。脊柱功能与神经肌肉控制[5]、肌肉力量[6]、本体感觉[7]等多种因素有关。脊柱功能下降可能会导致慢性疾病患病率上升、全球公共健康水平下降,给日益严重的老龄化社会带来沉重的负担[8]。本文旨在总结脊柱手法治疗的作用特点,从肌肉抑制、肌肉力量和本体感觉三个方面分析脊柱手法治疗改善脊柱功能的效应,以期厘清手法治疗对脊柱功能影响的最新研究成果和作用机制,为脊柱手法治疗应用于改善脊柱功能表现提供理论依据。郑尉 孙立冰 刘春华 John Downes 2021中国康复2021,36,11:3

14Data-Driven Discovery in Mineralogy: Recent Advances in Data Resources, Analysis, and Visualization显示文摘Large and growing data resources on the diversity, distribution, and properties of minerals are ushering in a new era of data-driven discovery in mineralogy. The most comprehensive international mineral database is the IMA database, which includes information on more than 5400 approved mineral species and their properties, and the mindat.org data source, which contains more than 1 million species/locality data on minerals found at more than 300 000 localities. Analysis and visualization of these data with diverse techniques—including chord diagrams, cluster diagrams, Klee diagrams, skyline diagrams, and varied methods of network analysis—are leading to a greater understanding of the co-evolving geosphere and biosphere. New data-driven approaches include mineral evolution, mineral ecology, and mineral network analysis—methods that collectively consider the distribution and diversity of minerals through space and time. These strategies are fostering a deeper understanding of mineral co-occurrences and, for the first time, facilitating predictions of mineral species that occur on Earth but have yet to be discovered and described.Robert M.

15从女人史到性别史显示文摘20世纪70年代中期以来,欧美历史学界研究著作中出现了一个趋势:研究初期,社会史和劳工史在女人史研究领域中占据着重要地位。伴随着女权主义和马克思主义之间对女人史起源的界定分歧,尤其是1968年社会运动之后,受第二波女权运动的社会大背景的影响,到20世纪80年代中期,女权主义学者开始从宏大结构分析的社会史转向更侧重于文化和话语分析的微观史研究,期冀用'性别'来区分将生理性(别)视为个人身份认同的物质属性的概念,认为男人和女人行为规范具有社会建构的可变性,揭示其贯穿时空流转被建构的本质。从80年代晚期到90年代中期,女权主义在理论和方法论争论中占据主导地位,英美历史学界接受后结构主义影响,从概念上挑战既有'男人'、'女人'社会范畴的稳定性,历史地研究性别关系在以往时代的演变,进一步动摇了历史学科以往的研究。通过分析、总结三个不同时段的四本代表作,揭示了女人史的发展路径:从作为社会史的女人史,到性别史,再到后结构主义性别史,以此探析女人研究领域分析的认识论基础。Laura Lee Downs 苑莉莉 2014中华女子学院学报2014,26,1:2
