Vascular and skeletal muscle oxidative capacity responses to continuous double and single leg cycling

Experimental Physiology, EarlyView.
Abstract The purpose of this work was to determine endothelial, microvascular, skeletal muscle oxidative capacity (SMOC) and cardiorespiratory responses to an acute bout of continuous single leg cycling (SLC) and double leg cycling (DLC). Ten recreationally active men and women volunteered to participate in this investigation and reported to the ...

Do auditory deviants evoke cortical state changes under anaesthesia? A proof‐of‐concept study

Experimental Physiology, EarlyView.
Abstract Context‐dependent sensory processing within the predictive coding framework relies on detecting mismatches between incoming stimuli and internal predictive models. Sensory deviants elicit prediction errors, seen as enhanced neural responses, that update these models and influence attention and behaviour.

Breathtaking heights: Lung mechanics and pulmonary extravascular fluid accumulation in female climbers during the K2 expedition

Experimental Physiology, EarlyView.
Abstract Female physiological responses to hypoxia remain underexplored, despite growing participation in mountaineering expeditions. Pulmonary interstitial oedema described during acute hypobaric hypoxia can be exacerbated by prolonged physical exercise. It is unclear whether these factors alter the mechanical properties of the respiratory system.

Early life stress and disruption of the ageing trajectory in female rats: Insights into the origins and mechanisms underlying the risk of hypertension

Experimental Physiology, EarlyView.
Abstract Menopause increases the risk of hypertension in women, yet the factors contributing to this important change remain unclear. Because early life stress has persistent and sex‐specific consequences on health, we hypothesized that ageing reveals the latent effects of neonatal maternal separation (NMS) on cardiovascular homeostasis in female rats.

Pulmonary arterial mechanoreceptors modulate exercise‐induced sympathetic activation in healthy humans during moderate‐intensity hypoxic exercise

The Journal of Physiology, EarlyView.
Abstract figure legend This randomized cross‐over trial (N = 12) addressed the hypothesis that selective reduction of pulmonary arterial pressure (i.e. manipulation of pulmonary arterial mechanoreceptor activation) during hypoxic exercise would reduce sympathetic outflow (muscle sympathetic nerve activity (MSNA)) in healthy humans.
