Perceptions of the existence and causes of structural violence in Ogoni communities,Nigeria

This article explores the perceptions of Ogoni people about the existence and causes of structural violence in their communities. It relies heavily on qualitative data collected from five oil-rich and three oil-poor Ogoni communities, between February and May 2014, during which 200 open-ended survey questionnaires were administered and 189 were returned. Three focus group discussions and 69 key informant interviews were also conducted. The findings of the article are that structural violence can be found in Ogoniland; it is manifested in both visible and invisible forms; it is blamed by elites on exogenous factors, but by the disadvantaged on both exogenous and endogenous factors; and it will only be eliminated by reducing inequality and increasing democratisation.     

外源性DHEA的体内代谢研究

目的:考察中国健康成人尿液中DHEA及其代谢物水平,评价滥用外源性DHEA后尿液中DHEA的代谢状况及其对内源性蛋白同化激素水平的影响。方法:六名健康志愿者口服120mgDHEA进行代谢试验,依据已建立的LC-MS/MS分析方法,测定受试者尿液中DHEA、睾酮、表睾酮、雄酮和苯胆烷醇酮的水平。结果:受试者尿液中内源性睾酮浓度明显低于国内外运动员。单剂量服用DHEA后,尿液中DHEA、雄酮和苯胆烷醇酮的浓度有明显的升高,达峰时间分别为:3.9±0.6h、3.4±0.9h和3.6±0.9h,并且均在12h后恢复至原有正常浓度范围。结论:监测滥用外源性的DHEA时,其尿液中的DHEA浓度是有效的技术指标。
