1Why have youth physical activity trends flatlined in the last decade? Opinion piece on “Global trends in insufficient physical activity among adolescents: a pooled analysis of 298 population-based surveys with 1.6 million participants” by Guthold et al.显示文摘1.No global progress on youth physical activity prevalenceTagedEnd TagedPDespite hundreds of intervention studies over decennia that have been dedicated to developing and testing programs and strategies to promote physical activity(PA)in adolescents,14 global inactivity levels remain persistently high.Based on self-report data from 1.6 million schoolgoing adolescents from 146 countries,Guthold et al.5 confirmed previous urgent calls to get adolescents more active.Researchers from the World Health Organization(WHO)recently published global prevalence rates and the first ever global time trends for insufficient PA in youth.They reported that more than 80%of school-going adolescents globally did not meet the current recommendations of at least 1 h of PA per day.Greet Cardon Jo Salmon 2020Journal of Sport and Health Science2020,9,4:6
2Fatigue crack propagation behavior of Ni-based superalloys after overloading at elevated temperatures显示文摘The fatigue crack propagation behavior of three superalloys subjected to a single overloading at elevated temperatures was investigated. The fatigue crack propagation rate FCPR versus stress intensity factor range data da/dN—ΔK were calculated using the two-point secant method. It was found that the crack growth rates of the investigated materials were retarded after overloading with an overload ratio R OL=1.6. The size of the plastic zone in the front of the crack tip and its relation to loading level were discussed. The overload retardation effects are attributed to crack closure. The fatigue damage in the plastic zone can also be a factor to explain the overload retardation.Xinyue Huang Liang Wang Yunming Hu Guangping Guo David Salmon Ying Li Wenxia Zhao 2016Progress in Natural Science:Materials International2016,26,2:4

5First isolation of glutinol and a bioactive fraction with good antiinflammatory activity from n-hexane fraction of Peltophorum africanum leaf显示文摘Objective: To investigate the anti-inflammatory activity of different fractions and glutinol(isolated compound),using nitric oxide synthase and cyclooxygenase(COX) inhibition as an indication of anti-inflammatory activity,Methods: Anti-inflammatory activity was evaluated using an in vitro assay determining the inhibition of the activity of pro-inflammatory enzyme model,Cyclooxygenases and inducible nitric oxide synthase are crucial enzymes involved in the pathogenesis of many chronic inflammatory conditions,Results: Sub-fraction F3.3 that was derived from n-hexane fraction of PA leaves significantly inhibited(P = 0.01) the catalytic activity of COX-2(IC50 = 0.67 μg/m L) better than isolated compound,glutinol(IC50 = 1.22 μg/m L),compound 2(CP2)(IC50 = 1.71 μg/m L) and sub-fraction F3.3.0(IC50 = 1.30 μg/m L),A similar trend was observed in investigation of the inhibition of nitric oxide synthesis in RAW 264.7 cells by F3.3,glutinol,CP2 and F3.3.0,Inducible COX-2 and inducible nitric oxide synthase are among potent signalling enzymes that exacerbate inflammation,Conclusions: Bioactive sub-fractions(F3.3 and F3.3.0) derived from the n-hexane fraction of PA had good anti-inflammatory activity,and the isolated compound,and glutinol may be useful as a template for the development of new anti-inflammatory drugs.Salmon A Adebayo Leshweni J Shai Jacobus N Eloff 2017Asian Pacific Journal of Tropical Medicine2017,10,1:2

7重组人肿瘤坏死因子与阿霉素抗人结肠癌细胞株(SW480)的序贯作用研究(英文)显示文摘目的评价 r Hu TNF和阿霉素抗人结肠癌细胞株的序贯作用。方法采用克隆生成试验 ( Hamburger- Salmon法 ) ,研究 r Hu TNF和 DOX序贯作用于 SW4 80细胞株后的抗增殖效果。结果对结肠癌细胞系 SW4 80 ,存在 DOX至 r Hu TNF序贯抗增殖作用 ;除反序贯给药情况外 ,出现显著的协同作用。结论在 DOX存在情况下 ,TNF的抗瘤作用增强 ,从而支持DOX可干扰细胞保护机制以使瘤细胞对 TNF细胞毒作用更为敏感的理论。骆云鹏 LIU Rosa SALMON Sydney E 2001免疫学杂志2001,17,4:2
8中药市场发展潜力展望显示文摘旨在介绍中药与西药药物理论的根本区别,阐述当前中药市场在国内外的发展状况,并对中药市场在国内外的发展潜力以及其所面临的机遇与挑战加以分析。通过查阅国内外文献并进行整理、分析和归纳,得出结论:由于中西方文化的差异及长期(半)封闭式的生产销售,造成中药海外市场的发展处于停滞状态。然而,大量数据显示,通过正当有效的销售渠道,中药市场在国内外的发展大有潜力。中药海外市场的发展不仅依赖于中药本身的研究开发,还依赖于各国对药品审核的相关政策法规。蔡茜 J.Warren Salmon 连桂玉 2003科技情报开发与经济2003,13,12:2
