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.

Anion Effect on the Thermometric Properties of Near‐Infrared Emitting Mn5+‐Activated Sr5(PO4)3X (X = F, Cl, Br) Apatite Phosphors

open access: yesAdvanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Mn5+‐activated Sr5(PO4)3X (X = F, Cl, Br) apatite phosphors exhibit tunable near‐infrared thermometric behavior across cryogenic to high temperatures. The correlation between local [PO4]3– geometry and optical properties enables the prediction of suitable hosts directly from structural information.
