A convenient three dimensional model to teach the arterial supply of the brainstem

open access: yesArtery Research, 2009
An easier approach of teaching the three dimensional nature of arteries of the brainstem is being proposed and aids the understanding of clinical vascular conditions of the brain.

Dopamine: The Essential Bridge Mediating Obstructive Sleep Apnea and Hippocampus‐Dependent Learning and Memory Impairments

open access: yesWorld Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Obstructive sleep apnea is a clinical syndrome that triggers a series of pathophysiologic changes, including disturbed sleep architecture, chronic intermittent hypoxia and hypercapnia, and ultimately severe cognitive dysfunction. The hippocampus plays a key role in various cognitive processes such as learning and memory.

Medullary infarction with central facial paralysis as the only symptom: a case report

open access: yesJournal of International Medical Research
The anatomical structure of the medulla oblongata is complex, its nerve fibers are dense, and its blood vessels are complex. Clinical manifestations of ischemic damage to the medulla oblongata are therefore relatively diverse, and include vertigo ...

A Case of Adult-Onset Alexander Disease Featuring Severe Atrophy of the Medulla Oblongata and Upper Cervical Cord on Magnetic Resonance Imaging

open access: yesCase Reports in Neurology, 2012
Adult-onset Alexander disease (AOAD) has been increasingly recognized since the identification of the glial fibrillary acidic protein gene mutation in 2001.

Evidence of internal structure validity of the nursing outcome “Mechanical Ventilation Weaning Response: Adult (0412)” for critically ill COVID‐19 patients

open access: yesInternational Journal of Nursing Knowledge, EarlyView.
Abstract Purpose To evaluate the evidence of internal structure validity of the nursing outcome (NO) “Mechanical Ventilation Weaning Response: Adult (0412)” of the NOs classification for critically ill COVID‐19 patients. Methods A methodological study focused on internal structural validation, part of a multicenter study, was carried out in the ...

Rapid generation of prion disease models using AAV‐delivered PrP variants in knockout mice

open access: yesBrain Pathology, Volume 36, Issue 4, July 2026.
We developed a rapid AAV‐based system to generate prion disease models in weeks rather than months. Following systemic AAV9P31 delivery of modified PrP to knockout mice, we achieved brain‐wide expression and successful propagation of both classical (RML) and atypical (GSS‐A117V) prion strains.

Clival Chondrosarcoma Associated With an Intra-Axial Cystic Medullary Lesion Responsive to Steroids

open access: yesFrontiers in Neurology, 2018
Introduction: Here we present a 75-year-old patient who was admitted with acute-onset right-sided hemiparesis, dysphagia, dysarthria and nystagmus. Repeated MRI scans showed two lesions with contact to one another: one solid stationary extra-axial lesion

The L108I polymorphism in mouse prion protein drives spontaneous disease and enhances transmission of atypical and classical prion strains

open access: yesBrain Pathology, Volume 36, Issue 4, July 2026.
A single amino acid change (L108I) combined with PrP overexpression drives spontaneous atypical prion formation in mice, enabling also efficient propagation of diverse prion strains. This model allows studying how spontaneous prion diseases arise and provides powerful tools for investigating strain emergence, transmission barriers, and mechanisms ...

Human brain matters: Navigating the neuropathology of COVID‐19

open access: yesBrain Pathology, EarlyView.
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

Variability in intracellular localization of D‐amino acid oxidase in choroid plexus epithelial cells

open access: yesThe FEBS Journal, EarlyView.
D‐amino acid oxidase (DAO) in choroid plexus epithelial cells (CPECs) shows vesicle‐like localization by histological and super‐resolution analyses. DAO colocalizes with peroxisomal, Golgi, endosomal, lysosomal, autophagosomal, and exosomal markers, indicating diverse subcellular distribution. This suggests DAO is transported within CPECs to metabolize
