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

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

Brain Pathology, Volume 36, Issue 6, November 2026.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.

Direct evidence implicating the asymmetrical dimethylarginine (ADMA)‐dimethylarginine dimethylaminohydrolase 1 (DDAH1) pathway in cerebrovascular dysfunction and stroke pathogenesis in mice

British Journal of Pharmacology, Volume 183, Issue 21, Page 6422-6443, November 2026.
Abstract Background and Purpose Asymmetrical dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS), whereas dimethylaminohydrolase 1 (DDAH1) is primarily responsible for its metabolism. However, the roles of DDAH1 in cerebrovascular regulation are poorly understood. Furthermore, despite evidence that elevated ADMA levels are

High Sinus, Lower Risk: A Paradigm Shift in Frontal Fracture Patterns

Clinical Otolaryngology, Volume 51, Issue 6, Page 944-951, November 2026.
ABSTRACT Objective The morphology of the frontal sinus (FS) has long been debated as a determinant of fracture type and severity. This study aimed to evaluate the association between sinus dimensions, fracture patterns, and clinical outcomes using real‐world data. Study Design Retrospective cohort study.

Exploring the Mechanism of Postpartum Cognitive Dysfunction in a Preeclampsia Rat Model via Multimodal Imaging

The FASEB Journal, Volume 40, Issue 19, 15 October 2026.
This schematic illustrates an L‐NAME‐induced preeclampsia (PE) rat model generated via L‐NAME administration to pregnant dams, wherein Morris water maze assessments confirmed progressive postpartum cognitive dysfunction that emerged at 10 days post‐partum and deteriorated further at 1 and 3 months post‐partum. Multimodal magnetic resonance imaging (MRI)
