Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Atypical choroid plexus papilloma treated with single agent bevacizumab

Rare Tumors, 2014
Choroid plexus papillomas (CPPs) are usually not malignant and occur in less than 1% of brain tumors in patients of all ages. They represent 3% of childhood intracranial neoplasms with a predilection in younger ages.

HierAnom‐Path: Zero‐Shot Rare Cancer Detection in Histopathology via Hierarchical Foundation Model Adaptation

Computational and Systems Oncology, Volume 6, Issue 1, December 2026.
ABSTRACT Rare cancers collectively represent 20%–25% of all malignancies yet yield fewer than 50 annotated whole‐slide images (WSIs) per subtype in publicly available archives, rendering supervised deep learning inapplicable. We present HierAnom‐Path, to the best of our knowledge, the first framework for zero‐shot rare cancer anomaly detection in ...

A Rare Case of Atypical Choroid Plexus Papilloma in an Adult Male Patient: A Case Report

Case Reports in Pathology
Choroid plexus tumors (CPTs) are rare neoplasms. Patient presentation varies depending on the location of the lesions. Gross total resection of primary lesions remains the gold standard for surgical treatment of CPTs.

Using Manganese‐Enhanced DCE‐MRI to Assess Blood‐Cerebrospinal Fluid Barrier Transport

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2083-2091, November 2026.
ABSTRACT PurposeWe developed a dynamic, heavily T2‐weighted (hT2w) FLAIR protocol to resolve acute Mn2+ transport kinetics, as a proxy for Ca2+, across the choroid plexus (ChP)—cerebrospinal fluid (CSF) interface, in vivo. By quantifying intercompartmental Mn2+ dynamics, and comparing these with Gd‐DOTA, we sought to characterize blood‐CSF‐barrier ...

Multiple Sclerosis and Viruses: « Liaisons Dangereuses »

Reviews in Medical Virology, Volume 36, Issue 6, November 2026.
ABSTRACT Multiple sclerosis (MS) is a complex, multifactorial neurodegenerative disease with an aetiology that is still partially elusive. Several risk factors are associated with MS development including genetic predisposition and various environmental stressors; however, recently, viral infections have gained significant attention as a crucial ...

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, Volume 36, Issue 6, November 2026.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive
