美国发布《应对全球灾难性生物风险的技术》报告
美国 全球灾难性生物风险的技术 报告
2018/11/23
近日,美国约翰霍普金斯大学健康安全中心发布《应对全球灾难性生物风险的技术》报告,提出对15种新兴技术进行战略投资可帮助世界应对包括传染病爆发在内的全球灾难性生物风险。全球灾难性生物风险(Global Catastrophic Biological Risk, GCBR)作为传染病紧急事件的一个子集,是涉及生物制剂的一种特殊风险。该风险可导致超出国家和国际组织以及私营部门集体控制能力的广泛性的突发灾...
国际知名医学杂志《柳叶刀传染病》近期发表的一项研究显示,一种药丸可以使人的血液对蚊子产生毒性并杀死它们,这将有利于防控蚊子传播疟疾等疾病。一组由英国主导的研究团队将139名来自肯尼亚的志愿者分成三组。疟疾患者被随机选择三天服用600mcg/kg或300mcg/kg伊维菌素或服用安慰剂。结果显示,两种剂量伊维菌素对蚊子的毒性可达28天之久。吸食伊维菌素摄入量较高患者的血液两周后,97%的蚊子死亡。
一种新型药浸蚊帐有助抗击疟疾
药浸蚊帐 抗击疟疾
2018/4/17
英国、坦桑尼亚等国研究人员在新一期英国《柳叶刀》杂志上发表报告说,他们开发出一种新型药浸蚊帐,能够阻挡对现有药浸蚊帐使用的杀虫剂产生耐药性的疟蚊,有助抗击疟疾。研究人员利用一种名为增效醚的杀虫剂开发出了新型药浸蚊帐。超过1.5万名坦桑尼亚儿童试用了这种药浸蚊帐。在为期两年的跟踪调查期间,研究人员发现,与使用拟除虫菊酯处理的蚊帐相比,使用增效醚处理过的药浸蚊帐使得第一年和第二年的疟疾流行率分别降低了...
美国科技媒体Ars Technica 近日公布了一项疫苗领域的重要进展:美国国家卫生研究院(NIH)宣布启动一种能对抗所有蚊子传播疾病的疫苗Ⅰ期临床试验。该疫苗名为AGS-v,针对的是蚊子的唾液而不是个别的病菌。蚊子对人类的“威胁”远不止耳边的嗡嗡声以及皮肤上留下的奇痒的包,它们携带并传播了各种病原体,比如大规模暴发的寨卡疫情,以及登革热、疟疾、黄热病等等。通过叮咬人类,蚊子每年让数亿人感染疾病,...
据美国《每日科学》报道,近日,科学家将3亿年前蟑螂的祖先物种以3D结构清晰地呈现出来。
英国伦敦帝国学院的科学家对一种叫做“Archimylacris eggintoni”的远古物种化石进行3D结构成像,这一物种是现代蟑螂、螳螂和白蚁的共同祖先。它们生活在3.59亿—2.99亿年前的石炭纪时期,当时地球生物正从海洋过渡至陆地。
