抗原变异可使得多种致病微生物易于逃避宿主免疫应答。表达在感染红细胞表面的恶性疟原虫红细胞表面蛋白1（PfPMP1）与感染红细胞、内皮细胞、树突状细胞以及胎盘的单个或多个受体作用，在黏附及免疫逃避中起关键的作用。每个单倍体基因组var基因家族编码约60种成员，通过启动转录不同的var基因变异体为抗原变异提供了分子基础。

2016 ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure: The Task Force for the diagnosis and treatment of acute and chronic heart failure of the European Society of Cardiology (ESC). Developed with the special contribution of the Heart Failure Association (HFA) of the ESC.

I have developed "tennis elbow" from lugging this book around the past four weeks, but it is worth the pain, the effort, and the aspirin. It is also worth the (relatively speaking) bargain price. Including appendixes, this book contains 894 pages of text. The entire panorama of the neural sciences is surveyed and examined, and it is comprehensive in its scope, from genomes to social behaviors. The editors explicitly state that the book is designed as "an introductory text for students of biology, behavior, and medicine," but it is hard to imagine any audience, interested in any fragment of neuroscience at any level of sophistication, that would not enjoy this book. The editors have done a masterful job of weaving together the biologic, the behavioral, and the clinical sciences into a single tapestry in which everyone from the molecular biologist to the practicing psychiatrist can find and appreciate his or

Objective The aim of this study is to assess the impact of the COVID-19 pandemic on mental health, type of delivery, and neonatal feeding of pregnant women with or without SARS-CoV-2 infection during gestation. Study Design The study was conducted online, and anonymous survey was distributed to mothers that delivered during the COVID-19 pandemic. Results The survey was completed by 286 women, and 64 women (22.4%) had COVID-19 during pregnancy. Women that had SARS-CoV-2 infection during pregnancy or at time of delivery had a significantly higher probability of being separated from the newborn (p < 0.0001) and a significantly lower probability of breastfeeding (p < 0.0001). The Edinburg Postnatal Depression Scale, to assess if mothers had symptoms of postnatal depression, showed that items suggestive of postnatal depression were relatively frequent in the whole cohort. However, women with SARS-CoV-2 infection during pregnancy reported higher probability of responses suggestive of postnatal depression in eight out of 10 items, with statistically significant differences in three items. Conclusion The COVID-19 pandemic affected the type of delivery and breastfeeding of pregnant women, particularly when they had SARS-CoV-2 infection. This, in turn, had an impact on the psychological status of the interviewed mothers, aspects that could benefit of special support.
