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.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

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.

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

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

The 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 ...

Endoscopic Thrombin Injection for Gastric Variceal Bleeding: A Systematic Review and Meta‐Analysis of Observational and Trial Data

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objective The safety of endoscopic thrombin injection (ETI) for treating the bleeding of gastric varix (GV) in patients with portal hypertension requires further evaluation. This meta‐analysis systematically reviews the available evidence on the efficacy and safety of ETI for GV bleeding.
