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 ...

Severe intraoperative hypercarbia undetected by continuous end-tidal CO2 monitoring in a chronic smoker undergoing one-lung ventilation

open access: yesThe Indian Anaesthetists' Forum, 2016
One-lung ventilation is known to alter the physiology and result in a discrepancy between end-tidal CO2 (ETCO2) and arterial blood CO2partial pressure despite protective mechanisms like hypoxic pulmonary vasoconstriction.

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

open access: yesMedComm – 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.

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

open access: yesComprehensive 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.

Intraoperative hypoxemia during one-lung ventilation: Is it still an anesthesiologists' nightmare? (hypoxemia during one-lung ventilation) [PDF]

open access: yesSerbian Journal of Anesthesia and Intensive Therapy, 2019
Lung isolation is used for various surgical and non-surgi-cal reasons. This type of ventilation carries the risk for va-rious degrees of ventilation/perfusion mismatch associa-ted with lateral decubitus position, one-lung ventilation (OLV) and opened ...

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 527-538, 1 February 2026.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...
