LongCOVID和身体不活动
不运动和COVID-19的顽固症状之间的联系正变得越来越明显。巴西圣保罗大学的研究人员最近进行的、发表在《科学报告》上的一项研究表明，那些在COVID-19中幸存下来并仍有至少一种持续症状的人，过着久坐不动的生活的可能性要大57%。此外，该研究发现，如果一个人有五个或更多的SARS-CoV-2感染的
利用longread生成个人转录组
斯坦福大学医学院的遗传学教授Michael Snyder及其同事利用Pacific Biosciences系统，对三个家庭成员的类淋巴母细胞转录组进行了测序，并将获得的reads与Illumina平台上获得的较短reads进行比较。通过这些转录组，他们开发出一名家庭成员的等位基因特异的全长转录组
