Glutathione (GSH) is an abundant thiol-containing tripeptide that functions in redox homeostasis, protein folding, and iron metabolism. In Saccharomyces cerevisiae, GSH depletion leads to increased sensitivity to oxidants and other toxic compounds, disruption of Fe-S cluster biogenesis, and eventually cell death. GSH pools are supplied by intracellular biosynthesis and GSH import from the extracellular environment.

This arrangement is thought to result from the clustering of neurons responding to similar inputs, constrained by intrinsic architecture and tuned by experience. We examined the malleability of this organization in individuals with unilateral resection of VOTC during childhood for the management of drug-resistant epilepsy.

We studied the adoption and compliance of CLABSI prevention bundle programs and CLABSI rates in ICUs in a large network of acute care hospitals across Canada.

Following menopause, mechanisms of female cardiovascular regulation change, which may be associated with sex-specific responses to orthostatic stress following bed rest. The purpose of our experiment was to investigate sex differences between healthy post-menopausal women and similar age men (age: 55-65 years) for their orthostatic tolerance and cerebrovascular responses to standing following bed rest.
