Macroscopical and histological characterization of the perineal membrane and deep perineal pouch

open access: yesJournal of Anatomy, EarlyView.
The existence of the deep transverse perineal muscle remains controversial. While the macroscopic appearance of the tissue in the deep perineal pouch differs between men and women, the differences in the histological composition of this fibromuscular plate is still unclear.

High‐elevation adaptation and gestational hypoxia jointly shape vascular development in a rodent placenta

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how environmental hypoxia and genetic adaptation to high altitudes jointly impact the development of the placental exchange surface in ways that might protect fetal growth potential. We used wild‐derived, lab‐born North American deer mice (Peromyscus maniculatus) from low‐elevation and high‐elevation environments (

Sex differences in neuromodulatory subcortical systems and their implications for Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Neuromodulatory subcortical systems (NSSs) are uniquely susceptible to dementia‐related pathology, leading to frequent molecular and behavioral impairments associated with altered function of these nuclei. Some of these systems display clear sex‐specific cytoarchitecture and signaling leading to distinct physiology and behavioral outputs in ...

Tyrosine Hydroxylase Deficiency Impairs TH Axonal Transport, Brain Function, and Neuronal Plasticity

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 2, March 2026.
ABSTRACT Tyrosine hydroxylase deficiency (THD) is a rare genetic disorder caused by biallelic pathogenic variants in the Th gene, leading to a deficiency in the rate‐limiting enzyme for the synthesis of dopamine (DA) and other catecholamine neurotransmitters.

Impact of diet and exercise in growth restricted female rats on nephron endowment in male fetuses

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 1365-1386, 1 March 2026.
Abstract Uteroplacental insufficiency impairs kidney development and programs male‐onset cardiorenal disease, which can be transmitted to subsequent generations. Maternal lifestyle factors can independently influence fetal kidney development, highlighting that the lifestyle of growth‐restricted females can have further influence on F2 kidney ...

Small is the New Large: Demonstration of how Microanalyses Elucidate Large‐Scale CO2 Uptake Through Mineralization

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 2, February 2026.
Imaging techniques like X‐ray microcomputed tomography and electron microscopy are integrated to understand the CO2 mineralization process at the pore‐scale. These techniques are used to characterise the reaction progression in basalt. They increase the reliability of reactive transport modeling and consequently improve the CO2 storage capacity ...

Inhibitory GABAergic Neuron Loss due to Oxidative Damage During Ex Vivo Acute Brain Slice Preparation Influences Genesis and Dynamics of Epileptiform Activity

open access: yesJournal of Neurochemistry, Volume 170, Issue 2, February 2026.
Ex vivo brain slice preparation is a popular technique in neuroscience research with many variations in preparation method. We compared two popular variations in brain slice preparation and found that the choice of brain slice preparation technique significantly affects the viability of neuronal preparation.
