α‐Adrenergic blockade impairs ductus venosus shunting during an acute period of fetal hypoxaemia without further deficits to cerebral oxygen delivery

Experimental Physiology, Volume 111, Issue 4, Page 1796-1807, 1 April 2026.
Abstract The fetal circulation has unique shunts, including the ductus venosus (DV), the tone of which dictates how much substrate‐rich blood returning from the placenta is streamed preferentially away from the liver and instead towards the heart. Herein, we aimed to use clinically relevant MRI techniques in sheep to measure indirectly induced changes ...

Combined multi‐metric assessment of diaphragm contractile function in healthy humans: Feasibility, validity and reliability

Experimental Physiology, Volume 111, Issue 4, Page 2308-2323, 1 April 2026.
Abstract The combined use of subcostal ultrasonography and respiratory manometry represents a novel, integrative method for quantifying diaphragm contractile function (force, velocity and power). We evaluated the technical feasibility, construct validity and within‐day test–retest reliability of this method during non‐volitional, volitional and ...
