Whole‐body hot water immersion effect on cerebral haemodynamics and subsequent cerebrovascular reactivity to carbon dioxide

Experimental Physiology, EarlyView.
Abstract To test the hypothesis that hot water immersion (HWI) improves cerebrovascular function via shear‐mediated mechanisms, this study determined cerebrovascular reactivity to carbon dioxide (CVRCO2${\mathrm{CV}}{{\mathrm{R}}_{{\mathrm{C}}{{\mathrm{O}}_2}}}$) before and after 60 min of 39°C HWI and a 21°C air control (CON) in 15 healthy ...

Effects of a high‐sugar mixed meal on cerebrovascular haemodynamics in young, healthy versus middle‐aged adults with cardiometabolic risk factors

Experimental Physiology, EarlyView.
Abstract Consumption of a high‐sugar mixed meal (HSMM) increases both glucose and insulin and elicits mixed vascular effects, with reduced microvascular blood flow but increased conduit artery diameter and blood flow. In this study, we sought to examine: (1) whether an HSMM elicits vascular segment‐specific effects within cerebrovasculature; and (2 ...

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

The Journal of Physiology, EarlyView.
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...

Acute exposure to mobile phone and assessment of internal cerebral circulation in young healthy subjects : a transcranial Doppler study [PDF]

, 2012
International audienceThe rapid worldwide increase in the use of mobile phones raises questions about the possible adverse effects of RF fields emitted by these devices. The temporal lobe of brain is closest to the mobile phone.

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
