Background:Determining the prevalence of doping in sport might be useful for anti-doping authorities to gauge the effectiveness of anti-doping policies implemented to prevent positive attitudes toward *** questionnaires and personal interviews,previous investigations have found that the prevalence of doping might be different among different sports disciplines;however,there is no sport-specific information about the proportion of adverse and atypical findings(AAF) in samples used for doping *** aim of the present investigation was to assess the differences in the frequency of adverse analytical and atypical findings among sports using the data made available by the World Anti-Doping ***:The data included in this investigation were gathered from the Testing Figures Reports made available annually from 2003 to 2015 by the World Anti-Doping *** Testing Figures Reports include information about the number of samples analyzed,the number of AAFs reported,and the most commonly found drugs in the urine and blood samples analyzed.A total of 1,347,213 samples were analyzed from the individual sports selected for this investigation,and 698,371 samples were analyzed for disciplines catalogued as team ***:In individual sports,the highest proportions of AAF were 3.3%±1.0% in cycling,3.0%±0.6% in weightlifting,and 2.9%±0.6% in *** team sports,the highest proportions of AAF were 2.2%±0.5% in ice hockey,2.0%±0.5% in rugby,and 2.0%±0.5% in *** and skating had the lowest proportions at(≤1.0%) for individual sports,and field hockey,volleyball and football had the lowest proportions for team sports(≤1.4%).Conclusion:As suggested by the analysis,the incidence of AAF was not uniform across all sports disciplines,with the different proportions pointing to an uneven use of banned substances depending on the *** information might be useful for increasing the strength and efficacy of anti-doping policies in those s

西花蓟马(缨翅目)是蓟马类中一种具有代表性的植物害虫,是一种能够对作物生产造成不利影响的多食性物种。因此,在欧盟,这些蓟马物种被作为检疫生物进行管理。西花蓟马以易感植物为食,并会传播几种导致严重植物疾病的病毒,从而对这些植物造成非常大的损害。以色列的供应占欧洲新鲜草本市场的50%,被认为是可食用鲜切花的主要供应市场。然而,在过去的十年中,由于没有可选的处理方法来控制检疫害虫而导致植物检疫失败,大大减少了出口量。目前尚无有效的采后杀虫处理方法。众所周知,熏蒸剂甲基溴(MB)具有植物毒性,尤其是对叶类产品和叶片,且与臭氧层的损耗有关。目前甲基溴仅能用作检疫和装运前熏蒸。甲酸乙酯(EF)被建议作为甲基溴的替代品,药效快、价格低廉、哺乳动物无毒性、环境无害、分解迅速,残留量极少或无残留。在以色列进行的30 g/m^(3)甲酸乙酯与二氧化碳(1∶1.6)混合处理不同花种的实验中,在10和15℃条件下分别处理1和1.5 h,对西花蓟马各虫态均有较好的防治效果。在15℃暴露2 h,可杀死全部害虫,对花或其保质期没有不良影响。因此甲酸乙酯熏蒸可作为一种检疫处理方法,也是甲基溴(MB)的可行替代方法。
