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.

Effects of high‐intensity interval training on cardiac function in hypertensive and normotensive men: Effects of antihypertensive treatment

Experimental Physiology, EarlyView.
Abstract Exercise training is recommended for individuals with hypertension because it has been shown to lower blood pressure and reverse left ventricular concentric remodelling and mass. However, it is unclear how hypertensive individuals respond in comparison to normotensive individuals and to what extent medical treatment affects the outcome of ...

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

Experimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Plant‐protein supplementation improves thermoregulatory responses and ameliorates markers of intestinal damage during exercise in the heat

Experimental Physiology, EarlyView.
Abstract Exercise in the heat often causes gastrointestinal (GI) disturbances, which can impair performance. Single amino acid supplementation can attenuate gut damage and enhance exercise tolerance; however, the effectiveness of innate amino acid blends from plant‐based proteins remains underexplored.

Pulmonary arterial mechanoreceptors mediate sustained sympathoexcitation during high altitude hypoxia in humans

Experimental Physiology, EarlyView.
Abstract Sympathetic nervous system activation is a hallmark of high‐altitude hypoxia, yet the afferent mechanisms remain incompletely defined. We examined the relative contributions of pulmonary arterial mechanoreceptors and carotid chemoreceptors – two excitatory pathways co‐activated by hypoxia – to sustained sympathoexcitation at altitude.

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.

Hysterosalpingography with color Doppler ultrasonography

American Journal of Obstetrics and Gynecology, 1991
To assess the accuracy of the diagnosis of tubal occlusion with the use of color Doppler flow ultrasonography and hysterosalpingography, 129 infertile women were studied. All 129 women had the procedure performed with an ATL Ultramark 9 (Advanced Technology Laboratories, Bothel, Wash.) color Doppler ultrasonography machine. Eighty-five of the 129 women
