Haemodynamic effects of selective venoconstriction with centhaquine in spontaneously breathing patients with mixed hypovolaemic‐vasodilatory shock

open access: yesExperimental Physiology, EarlyView.
Abstract Circulatory shock remains difficult to manage because fluid resuscitation and catecholamines may exacerbate vascular dysfunction and tissue hypoperfusion. This prospective physiological analysis, embedded within a multicentre phase IV study, examined whether selectively targeting the venous circulation with centhaquine improves circulatory ...

The impact of biological sex and stroke volume constituents on heterogeneity in the Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$ relationship and skeletal muscle saturation during cycling

open access: yesExperimental Physiology, EarlyView.
Abstract Interindividual variability in the cardiac output (Q̇$\dot{Q}$) to the rate of oxygen consumption (V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) slope (Q̇$\dot{Q}$–V̇O2${{\dot{V}}_{{{{\mathrm{O}}}_2}}}$) in healthy males is related to stroke volume (SV); however, the impact of differences in left ventricular (LV) structure and function as well as ...

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

open access: yesThe 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.

In Vivo Dynamic Coronary Arteries Blood Flow Imaging Based on Multi‐Cycle Phase Clustering Ultrafast Ultrasound

open access: yesAdvanced Science
Echocardiography is the most primary clinical modality for dynamic cardiac imaging. However, the vigorous motion of myocardial tissue inherently causes inevitable signal aliasing between blood flow and myocardial tissue in traditional Doppler ultrasound ...

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

Post‐exercise ketone supplementation improves endurance performance and mitochondrial adaptations during an 8‐week endurance training intervention

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐eight trained males completed 8 weeks of supervised indoor cycling training, receiving post‐exercise and pre‐sleep ketone monoester (KE, n = 14) or isocaloric placebo (CON, n = 14). Both groups improved 30 min time‐trial performance with training, but KE achieved a 4% higher power output than CON at the end of the training

Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

EUROPEAN CERTIFICATION OF CLINICAL COMPETENCE IN ADULT ECHOCARDIOGRAPHY ISSUED IN BELGIUM

open access: yes, 1995
In accordance with the European proposals, adapted guidelines are proposed for a certification of clinical competence in adult echocardiography, with transoesophageal echocardiography as a special option.
