Regional changes in cerebral blood flow between the upright and supine posture and over 3 days of bed rest

Experimental Physiology, EarlyView.
Abstract A reduction in cerebral blood flow (CBF) has been observed during spaceflight and bed rest. We aimed to examine the magnitude and regional heterogeneity of the decrease in CBF during bed rest compared to posture changes on Earth. Seventeen participants (age, 29 ± 9 years, 7 females) were studied in the upright and supine posture and over 3 ...

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

Experimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.
