Association between polycystic ovary syndrome and environmental endocrine disruptors: the pathogenetic mechanisms involved [PDF]
, 2016 摘要 多囊卵巢综合征(Polycysticovarysyndrome，PCOS)是一种在育龄妇女中常见的内分泌紊乱疾病，其常见特征为稀发排卵或少排卵、高雄激素血症、卵巢多囊化。PCOS的发病机制尚不明确，而许多研究表明环境因素是导致PCOS发病的重要因素。 本实验收集育龄妇女流行病学资料，并利用气象色谱-质谱联用检测了84名PCOS患者及94名对照组血清中多种环境中内分泌干扰物(endocrinedisruptingchemicals，EDCs)的含量。结合流行病调查资料和相关激素代谢物质水平 ...

Rare Metals, EarlyView.ABSTRACT This study elucidates the oxidation mechanisms governing Y/Hf‐doped AlCoCrFeNiTi high‐entropy alloys (HEAs) and reveals the pivotal role of fabrication processes in dictating high‐temperature oxidation behavior. We demonstrate that casting and spark plasma sintering (SPS) promote Y/Hf segregation, resulting in heterogeneous oxide formation and
