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.

An acute crossover trial of passive movement training with and without blood flow restriction to determine the impact on postprandial glycaemia

Experimental Physiology, EarlyView.
Abstract During glucose uptake into muscle, GLUT‐4 can translocate with stimulus from insulin or muscle contraction via exercise, but some exercise‐intolerant populations are unable to benefit from improved glycaemic control. We investigated how passive movement training (PMT) and passive movement training with blood flow restriction (PMT+BFR) could be

Sex differences in macrovascular responsiveness: Acute effects of hot water immersion versus aerobic exercise in overweight older adults

Experimental Physiology, EarlyView.
Abstract Recent studies have focused on the potential benefits of heat exposure for cardiovascular health. However, the acute effects of heat therapy on conduit arteries remain unclear, particularly in overweight and obese older males and females. This study aimed to compare core temperature (Tc), heart rate (HR), and brachial, femoral, and carotid ...

Comparison of exercise training and repeated hot water immersion on vascular function in overweight older adults

Experimental Physiology, EarlyView.
Abstract Recent studies suggest that heat exposure may benefit cardiovascular health, but in overweight and obese older adults, the chronic effects of heat therapy on artery function are still uncertain. We aimed to compare the effects of 12 weeks (3×/week, 40 min) of aerobic exercise (EXE) to hot water immersion (HWI) and an inactive control group ...

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Aorta and brachiocephalic artery pathology in dyslipidemia

Российский кардиологический журнал, 2005
Aorta and brachiocephalic artery atherosclerosis in various types of dyslipidemia (DLP) were examined. Twenty-six participant demonstrated combination of aortic and coronary or cerebral atherosclerosis: 5 patients had aortic isthmus stenosis, 8 ...

The role of acid‐base balance in cerebrovascular and ventilatory responses to CO2 during 10 h normobaric hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend During 10 h exposures to normobaric hypoxia exposure there was a selective leftward shift in ventilatory response to hyperoxic hypercapnic rebreathing, but not the cerebrovascular response. The key findings are that the resetting of the central chemoreflex to lower PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$ during early hypoxic ...
