No difference in mean middle cerebral artery blood velocity responses between lower‐ and upper‐body unilateral resistance exercise in untrained individuals

Experimental Physiology, EarlyView.
Abstract Dynamic resistance exercise (RE) produces sinusoidal fluctuations in blood pressure that are mirrored by middle cerebral artery blood velocity (MCAv). However, whether lower‐ or upper‐body RE elicits a differential cerebrovascular response has not yet been examined.

Factors influencing heart rate variability in nurses following night shifts: a prospective observational clinical study

BMC Nursing
Background Heart rate variability (HRV) has been established as a key indicator of autonomic nervous system activity, reflecting both sympathetic and parasympathetic modulation.

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

Experimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Bilateral dynamic cerebral autoregulation assessment during endovascular treatment in large‐vessel occlusion stroke

Experimental Physiology, EarlyView.
Abstract Recanalization by endovascular treatment (EVT) is effective in acute ischaemic stroke caused by large‐vessel occlusion. Better understanding of the pathophysiology could possibly identify targets for improving peri‐procedural management and thereby patient outcome.

Transcranial Doppler Monitoring of Intracranial Pressure Plateau Waves

Neurocritical Care, 2016
Background Transcranial Doppler (TCD) has been used to estimate ICP noninvasively (nICP); however, its accuracy varies depending on different types of intracranial hypertension.

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 ...
