Recent evidence points to an important role for the microbiome in regulating brain function and behavior. Here, Morais et al. show that birth by C-section results in a different pattern of microbiota colonization with long-term behavioral consequences in the mouse. Targeting the gut microbiota reverses social behavioral effects of C-section.

Eisfeld et al. comprehensively evaluated changes in host molecules in plasma and peripheral immune cells of Ebola virus disease (EVD) patients. Their results suggest new mechanisms of EVD pathogenesis and putative biomarkers for predicting EVD outcomes. Moreover, datasets associated with this work are an important community resource for further research.
Jul 12, 2020· Propelled to propenePropene is produced in a three‐step enzymatic cascade from n‐butanol via butanal and butyric acid, with the last step being oxidative decarboxylation alyzed by OleT JE.Variation of the supply of redox donors demonstrates the peroxygenase nature of OleT JE.A mutational study led to a new variant, OleT V292I, which shows significantly higher activity towards
Designing technologies that mitigate the low-dose adverse effects of exposures to large-volume, everyday-everywhere chemicals such as bisphenol A (BPA, 1a) requires an understanding of the scope of the exposures and the nature of the adverse effects.Therefore, we review the literature of, (i) the occurrences of 1a in humans, gc headspace vials manufacturer and products and the effectiveness of widely deployed
