An Increased Risk for Ischemic Stroke in the Short-Term Period following COVID-19 Infection: A Nationwide Population-Based Study.

Introduction: The association disclosed between coronavirus disease 2019 (COVID-19) infection and ischemic stroke (IS) raises concern. The exact risk periods, which were not consistent between studies, require further investigation.

Methods: We linked two national databases: the COVID-19 database and the Israeli National Stroke Registry.

Ferric reductase-related proteins mediate fungal heme acquisition.

Heme can serve as iron source in many environments, including the iron-poor animal host environment. The fungal pathobiont expresses a family of extracellular CFEM hemophores that capture heme from host proteins and transfer it across the cell wall to the cell membrane, to be endocytosed and utilized as heme or iron source. Here, we identified Frp1 and Frp2, two ferric reductase (FRE)-related proteins that lack an extracellular N-terminal substrate-binding domain, as being required for hemoglobin heme utilization and for sensitivity to toxic heme analogs.

Diverse heliorhodopsins detected via functional metagenomics in freshwater Actinobacteria, Chloroflexi and Archaea.

The recently discovered rhodopsin family of heliorhodopsins (HeRs) is abundant in diverse microbial environments. So far, the functional and biological roles of HeRs remain unknown. To tackle this issue, we combined experimental and computational screens to gain some novel insights.

Overestimation of body weight and its association with parental, teacher and peer support: evidence from the Israeli Health Behaviours in Schools survey.

Objective: To investigate the association between family, teachers and peer support patterns on gaps in adolescent's weight perceptions.

Design: A cross-sectional, school-based survey collected information on weight and height, weight perception, socio-economic and family characteristics and social support. Principal component analysis (PCA) was performed to capture social support patterns (SSP).

Head mounted DMD based projection system for natural and prosthetic visual stimulation in freely moving rats.

Novel technologies are constantly under development for vision restoration in blind patients. Many of these emerging technologies are based on the projection of high intensity light patterns at specific wavelengths, raising the need for the development of specialized projection systems. Here we present and characterize a novel projection system that meets the requirements for artificial retinal stimulation in rats and enables the recording of cortical responses.
