Acute intermittent hypercapnic hypoxia augments left ventricular contractility

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

open access: yesThe Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.

Adamts1 Exacerbates Post‐Myocardial Infarction Scar Formation via Mechanosensing of Integrin α8

open access: yesAdvanced Science, Volume 12, Issue 46, December 11, 2025.
Proposed mechanistic model of ADAMTS1‐ITGα8 mechanotransduction in post‐MI scar formation. Schematic illustration showing the mechanistic pathway by which endothelial cell (EC) derived Adamts1 regulates cardiac fibroblast activation through ITGα8‐mediated mechanotransduction following myocardial infarction (MI).
