Altitude‐induced plasticity of respiratory central–peripheral chemoreflex interaction
The Journal of Physiology, EarlyView.Abstract figure legend Altitude‐induced plasticity of respiratory central–peripheral chemoreflex interaction. Seventeen participants completed modified rebreathing tests at low altitude and after 7–10 days of acclimatization at high altitude (3500 m). Central chemoreceptor activation was isolated using hypercapnic hyperoxia (end‐tidal PO2${{P}_{{{O}_2}}

Hyperoxia attenuates apnea-induced responses.
, 2014 A. Changes in mean arterial pressure, heart rate and thoracic pressure in WKY and SHR rats during apnea in normoxia (21% O2) and hyperoxia (100% O2). Error bars indicate SEM. MAP = mean arterial pressure, HR = heart rate, TP = thoracic pressure. B.

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2755-2766, December 2026.ABSTRACT Purpose Cerebrovascular reactivity (CVR) provides an important index of vascular health and is conventionally quantified using a hypercapnic gas or breath‐hold challenge in conjunction with blood‐oxygen‐level‐dependent functional magnetic resonance imaging (BOLD‐fMRI).

Severe hyperoxia increases liver expression of MMP-9.
, 2014 Western blotting analysis of MMP-9 expression in neonatal rat livers exposed to moderate and severe hyperoxia. a) ambient air; b) 60% hyperoxia; c) 95% hyperoxia. Each membrane has been probed with anti-tubulin antibody to verify loading evenness.

European Journal of Sport Science, Volume 26, Issue 11, November 2026.ABSTRACT Dyspnea occurs during high‐intensity running in healthy trained individuals and may limit endurance performance. Given that L‐menthol inhalation can alleviate dyspnea in other contexts, we investigated whether L‐menthol inhalation reduces dyspnea and improves endurance performance during high‐intensity running in healthy trained individuals ...
