Cerebral haemodynamic responses to inspiratory muscle work

Experimental Physiology, EarlyView.
Abstract Fatiguing inspiratory work has been shown to evoke a sympathetically mediated reflex that has systemic cardiovascular consequences, including increases in heart rate and blood pressure and a decrease in resting limb vascular conductance. Moreover, the response to this reflex appears to be attenuated in females compared with males.

Noradrenergic regulation of skeletal muscle oxygen pressures: Impact of heart failure with preserved ejection fraction and heat therapy

Experimental Physiology, EarlyView.
Abstract Attenuation of sympathetic vasoconstriction during exercise (functional sympatholysis) contributes to skeletal muscle oxygen delivery–utilization matching. However, the extent to which muscle contractions impact noradrenergic regulation of interstitial oxygen pressures (PO2is${P_{{{\mathrm{O}}_2}}}_{{\mathrm{is}}}$; the driving force for blood–

ZFP36 inhibits the pro‐apoptotic effects of transforming growth factor β1 on mitral valve interstitial cells via the GTP‐binding protein 6 pathway in mitral valve prolapse

Experimental Physiology, EarlyView.
Abstract The objective of this work was to investigate the role of ZFP36 in mitral valve prolapse (MVP). Mitral valve and plasma were collected to assess the expression of ZFP36, transforming growth factor β (TGF‐β), collagen and elastin and apoptosis rates.

Cardioprotection via vagus nerve stimulation preconditioning: Reducing ischaemia–reperfusion injury and arrhythmic risk

Experimental Physiology, EarlyView.
Abstract Acute myocardial infarction is a leading cause of morbidity and mortality, with ischaemia–reperfusion (I/R) injury exacerbating myocardial damage. Vagus nerve stimulation (VNS) has been reported to exert cardioprotective effects, but its efficacy in preconditioning against I/R injury requires further investigation.

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.

Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.
