The social determinants of health (SDOH) have been recognized as an important contributor to an individual's health status. A valid and reliable instrument is needed for researchers and clinicians to measure SDOH. However, there is considerable variability in the screening methodologies, as well as a lack of standardization in definitions and methods for capturing and reporting SDOH data for both electronic health record software vendors and national experts on SDOH.

Antibody-based research applications are critical for biological discovery. Yet there are no industry standards for comparing the performance of antibodies in various applications. We describe a knockout cell line-based antibody characterization platform, developed and approved jointly by industry and academic researchers, that enables the systematic comparison of antibody performance in western blot, immunoprecipitation and immunofluorescence.

Cryphonectria hypovirus 1 (CHV1) is successful in controlling , the causal agent of chestnut blight, but little is known regarding its transmission to other fungi, for example the European . In this study, CHV1 was transmitted (circa 200,000-800,000 copies/microliter) to seven isolates from infected . Reverse transmission to virus-free (European 74 testers collection) was achieved, although it was less successful (250-55,000 copies/µL) and was dependent on the vegetative compatibility (VC) group.

Background: Heart failure (HF) subtype, depressive symptoms, and physical inactivity independently contribute to survival outcomes, but the effect of the interaction of these variables on survival outcomes remains unknown.

Objectives: We aimed to determine whether depressive symptoms and engagement in physical activity differentially interact to predict the combined endpoint of all-cause death or rehospitalization among patients with HF and reduced (HFrEF) or preserved ejection fraction (HFpEF).

Methods: This study was a secondary analysis.

Synaptotagmin-1 is a synaptic vesicle transmembrane protein that senses calcium influx via its tandem C2-domains, triggering synchronous neurotransmitter release. Disruption to is associated with neurodevelopmental disorders, highlighting the importance of identifying high-quality research reagents to enhance understanding of Synaptotagmin-1 in health and disease. Here we have characterized thirteen Synaptotagmin-1 commercial antibodies for western blot, immunoprecipitation, immunofluorescence and flow cytometry using a standardized experimental protocol based on comparing read-outs in knockout cell lines and isogenic parental controls.
