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 ...

ROC‐325 Attenuates Hypoxia‐Induced Pulmonary Hypertension Through Dual Inhibition of Autophagy and Hypoxia‐Inducible Factor 2α Signaling

MedComm – Future Medicine, Volume 5, Issue 1, March 2026.
In hypoxia‐induced pulmonary hypertension, endothelial HIF‐2α accumulation and autophagic activation drive vascular remodeling. We demonstrate that the novel lysosomal inhibitor ROC‐325 simultaneously attenuates this pathogenic autophagy and promotes HIF‐2α degradation.

Disseminated Invasive Aspergillosis in a Young Patient With Chronic Alcohol Use and Seemingly Preserved Immunocompetence: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Invasive aspergillosis, though typically seen in immunocompromised patients, can also affect immunocompetent individuals and mimic pulmonary malignancy. This case highlights the importance of considering fungal infections in the differential diagnosis of chronic respiratory symptoms, particularly in patients with risk factors such as heavy ...

The Impact of High‐Intensity Exercise in Normobaric Hypoxia on Right Ventricular Function in Trained and Untrained Men—An Echocardiographic Study

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
A single bout of high‐intensity exercise to volitional exhaustion under acute normobaric hypoxia (~3000 m a.s.l.; FiO2 = 14.4%) does not induce greater alterations in right ventricular systolic function compared to normoxia in either trained or untrained healthy men.
