工业 清洗剂 患帕金森氏症
2010/2/10
据国外媒体报道，根据2010年2月8日公布的一项研究发现，暴露在三氯乙烯环境下的工人可能面临更大的帕金森氏症患病风险。三氯乙烯这种化学制品一度被广泛用于清洗汽车零部件等金属。在2010年4月10日至17日于多伦多举行的美国神经病学学会第62届年会上，研究人员将报告他们的发现。
《自然》：严重肥胖可能由成段基因缺失导致
自然 严重肥胖 基因
2010/2/8
英法等多国研究人员在最新一期《自然》杂志上刊登研究报告说，一些严重肥胖的人体内缺少连成片的数十个基因，这是首次发现成段的基因缺失与肥胖症有关。研究人员首先分析了一批肥胖症患者的基因图谱，发现31人体内都缺失相同的DNA片段，这段DNA位于染色体16p11.2上，其中包含约30个基因。研究人员随后又对欧洲多国的约1.6万人进行了大规模调查，又在19名严重肥胖者体内发现了相同的基因缺失情况。而在体重正...
研究发现女性到30岁时已消耗90%卵子库存
女性 30岁 卵子库存
2010/2/4
据《每日电讯报》1月27日报道，科学家通过研究发现，妇女到30岁时就已经消耗约90%的“卵子库存”。尽管三四十岁的妇女仍能排卵，但是不仅其“卵子库存”已经所剩无几，而且卵子质量下降，不利于生出健康的婴儿。这一发现揭示了中年妇女年龄越大越难受孕的奥秘。这一最新研究是由苏格兰圣安德鲁斯大学和爱丁堡大学科研人员完成的，发表在《公共科学图书馆·综合》（PLoS ONE）上。所谓“卵子库存”是指一名女性一生...
