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

Experimental Physiology, EarlyView.
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

Experimental Physiology, EarlyView.
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

Use and reporting of systematic review methodology in EFSA scientific opinions on animal health and welfare

Frontiers in Veterinary Science
IntroductionDespite the growing use of systematic reviews of animal studies, it remains unclear how often systematic review methodology – such as detailed search strategies, critical appraisal, and protocol registration – is applied in regulatory ...

Posterior parietal cortex oscillatory activity reflects persistent spatial memory impairments induced by early hippocampal amyloidosis in male mice

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic representation of the spatiotemporal progression of the deleterious effects of early amyloidosis. Beginning as early as 1 h after i.c.v. injection of oligomeric Aβ1‐42, alterations in hippocampal function emerge, including aberrant oscillatory activity, deficits in synaptic plasticity and impairments in habituation ...

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

In silico predictions of action potential propagation in doxorubicin cardiotoxicity: A parametric study using preclinical 3D magnetic resonance imaging‐based fibrotic left ventricle models

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the study's methodology and key findings. In a preclinical swine model, doxorubicin administration induced cardiotoxicity, characterized by diffuse fibrotic remodelling and altered electrical function, as assessed by magnetic resonance (MR) imaging and electrophysiological mapping.

Lactate potentiates NMDA receptor currents via an intracellular redox mechanism targeting GluN2B subunits: implications for synaptic plasticity

The Journal of Physiology, EarlyView.
Abstract figure legend Astrocyte‐derived lactate enhances neuronal NMDA receptor (NMDAR) function and synaptic plasticity through a redox‐ and CaMKII‐dependent mechanism. Lactate enters neurons via monocarboxylate transporters (MCTs) and is oxidized by lactate dehydrogenase (LDH) to pyruvate, generating NADH and increasing the intracellular NADH/NAD ...

Electroactive Biodegradable Nerve Conduits Based on Alginate–Gelatine Polymer Matrix Modified With Inorganic Nanoparticles

Natural Sciences, Volume 6, Issue 2, April 2026.
The effects of ZnO, fullerene C60 and polyaniline (PANI) nanoparticles in hybrid nerve conduits are explored. The composites show enhanced electrical conductivity, permeability to physiological fluids and mechanical stability. The biocompatibility of composites is confirmed by in vivo and in vitro studies.

3,4‐Methylenedioxymethamphetamine (MDMA) does not induce robust psychomotor activation and 50‐kHz ultrasonic vocalisations in tryptophan hydroxylase 2 (Tph2)‐deficient rats lacking serotonin in the central nervous system

British Journal of Pharmacology, Volume 183, Issue 7, Page 1539-1556, April 2026.
Background and Purpose 3,4‐Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy, is a psychostimulant with entactogenic properties and known to induce arousal and euphoria. As an amphetamine derivate, MDMA acts on the monoamine systems in the brain and stimulates release of dopamine (DA), noradrenaline (NA) and serotonin (5‐HT), yet their ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

Biological Reviews, Volume 101, Issue 2, Page 848-868, April 2026.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.
