Surface mutation lets canine parvovirus jump to other species
Surface mutation canine parvovirus jumpother species
2016/4/25
Canine parvovirus, or CPV, emerged as a deadly threat to dogs in the late 1970s, most likely the result of the direct transfer of feline panleukopenia or a similar virus from domesticated cats.CPV has...
寨卡病毒结构图首次绘制（图）
美国普渡大学 寨卡病毒结构图
2016/4/5
据美国普渡大学最新消息，由该校牵头的一个研究团队首次确定了寨卡病毒的结构，揭示出其内部关键位置，为开发有效的抗病毒疗法和疫苗提供了路线图。相关论文发表在2016年3月31日出版的《科学》杂志上。该团队还确定了寨卡病毒内部与登革热、西尼罗河病毒、黄热病、流行性乙型脑炎等其他同科病毒不同的地方。在近原子尺度的分辨率下，可以看到病毒结构的关键特征，成群的原子组成特殊的化学结构，如天然氨基酸等，均可被识别...

更多证据指向寨卡病毒引发小头症
寨卡病毒 小头症
2016/3/17
目前在美洲多国肆虐的寨卡病毒与新生儿小头症之间是否存在因果关系，是医学界当前研究热点。一项对几年前法属波利尼西亚寨卡疫情的回顾性评估显示，孕妇在孕期前3月感染寨卡病毒后，出现小头症等出生缺陷的风险约为1%，大大高于通常情况。相比之下，通常情况下医学界记录到的新生儿小头症比率大约为万分之二。研究负责人、法国巴斯德研究所西蒙·科舍梅在新闻公报中说：“我们的分析强烈支持目前的假设，即新生儿小头症与孕期前...

脓毒症处理新设备能识别有害细胞因子
脓毒症 识别 有害细胞因子
2016/3/1
据美国麻省理工学院（MIT）消息，一种新型脓毒症处理设备最近获得该校斯隆卫生护理创新奖。新设备能选择性地除去血液中多余的细胞因子，过滤血液更加安全高效，预防器官衰竭，还能与现有设备结合使用大大降低治疗成本。脓毒症是一种常见的威胁生命病症，由血液感染引起一种叫做细胞因子的分子增加而导致，这会引起全身性炎症反应综合征（SIRS）造成器官衰竭。获奖团队GoodSIRS由波士顿儿童医院、麻省理工学院和哈佛...
一种强效埃博拉抗体发现
埃博拉 抗体
2016/2/29
美国《科学》杂志2016年2月26日发表的两项新研究显示，从20多年前埃博拉幸存者的血液中分离出的一种抗体，有望用作强效的埃博拉治疗药物。在第一项研究中，美国国家卫生研究院等机构的科学家从血清中分离出了一种叫mAb114的抗体。所用的血清来自1995年刚果（金）埃博拉疫情暴发时一名幸存者，于2006年提取。3只猕猴在感染埃博拉病毒5天后，用这种抗体连续治疗3天，结果全部存活了下来，并且不再有病毒感...
