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

open access: yesExperimental 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 ...

Methodological comparison of fetal brain 1H‐MRS data analysis techniques and gestational age analysis using LCModel in the fetal sheep brain

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1597-1611, 1 April 2026.
Abstract Proton (1H) magnetic resonance spectroscopy (MRS) is a non‐invasive imaging technique that can be used to assess brain metabolism. Establishing reference levels of fetal brain metabolites in a translatable preclinical model is crucial for identifying subtle deviations from normal cerebral development. Herein, we developed a 1H‐MRS protocol for

Oxygen and glucose supplementation increases rates of linear growth and cell proliferation in growth‐restricted fetal sheep

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 2778-2795, 1 April 2026.
Abstract figure legend Effects of sustained oxygen and glucose supplementation on growth and cellular proliferation in growth‐restricted fetuses. This study evaluated whether supplemental oxygen and glucose could improve growth rates in sheep fetuses with established fetal growth restriction (FGR). Following the induction of placental insufficiency and

General practice veterinarians’ attitudes towards avian influenza: A COM‐B analysis of barriers to backyard poultry treatment

open access: yesVeterinary Record, Volume 198, Issue 6, Page e237-e247, 14/21 March 2026.
Abstract Background The recent expansion of highly pathogenic avian influenza (HPAI) H5N1 to non‐avian species in the United States has intensified public health‐related concerns. In Great Britain, low veterinarian confidence in seeing and treating birds creates potential barriers to HPAI diagnosis and reporting.
