Aging‐Driven Blood–Brain Barrier Dysfunction and Its Impact on CNS Cancer Susceptibility: A Comprehensive Narrative Review

open access: yesAging and Cancer, EarlyView.
Aging weakens the blood–brain barrier (BBB), increasing susceptibility to CNS cancers and complicating treatment. This review examines BBB deterioration, its impact on drug delivery, and potential interventions like targeting neuroinflammation and advanced therapies.

The burden of intracranial atherosclerosis on cerebral small vessel disease: A community cohort study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Exploring the prevalence and association between intracranial atherosclerosis (ICAS) and cerebral small vessel diseases (CSVD), this study delved beyond the current scope, utilising high‐resolution vessel wall MRI (HRVW‐MRI) to investigate how subtle changes in intracranial atherosclerotic features influence the various burdens of ...

A Hierarchical Image Matting Model for Blood Vessel Segmentation in Fundus images [PDF]

open access: yesarXiv, 2017
In this paper, a hierarchical image matting model is proposed to extract blood vessels from fundus images. More specifically, a hierarchical strategy utilizing the continuity and extendibility of retinal blood vessels is integrated into the image matting model for blood vessel segmentation. Normally the matting models require the user specified trimap,

Clinical Phenotyping of Long COVID Patients Evaluated in a Specialized Neuro‐COVID Clinic

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To report Long COVID characteristics and longitudinal courses of patients evaluated between 4/14/21–4/14/22 at the University of Pennsylvania Neurological COVID Clinic (PNCC), including clinical symptoms, neurological examination findings, and neurocognitive screening tests from a standardized PNCC neurological evaluation approach ...

A reduced model for solute transport in compliant blood vessels with arbitrary axial velocity profile [PDF]

open access: yesarXiv, 2019
We derive a reduced model of solute transport in blood based on the center manifold theory. The derivation is carried out on a convection diffusion equation with general axial and radial velocity profiles in a blood vessel of varying cross section. We couple the resulting one dimensional equation to a reduced model for blood flow in a compliant vessel.

Cerebral Amyloid Angiopathy Is Associated With Higher R2 Relaxation Rate: An MRI and Pathology Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cerebral amyloid angiopathy (CAA) involves β‐amyloid deposition in the walls of cortical and leptomeningeal small vessels. Transverse relaxation rate (R2) is a major source of contrast in MRI. This study tested the hypothesis that CAA is associated with R2, extracted the spatial pattern of CAA‐related R2 abnormalities, and evaluated ...

MULTI-STAGE TREATMENT OF TETRALOGY OF FALLOT: FROM PALLIATIVE INTERVENTIONS TO HYBRID Y-STENTING OF THE PULMONARY ARTERY BIFURCATION STENOSIS AND RADICAL CORRECTION (CLINICAL CASE)

open access: yesПаёми Сино
Primary radical correction of tetralogy of Fallot (ToF) is an optimal surgical option; however, in some conditions, in particular with concomitant extracardiac pathology and hypoplasia of the pulmonary artery (PA) branches, this intervention is not ...

A review of the current state of pannexin channels as they relate to the blood vessel wall

open access: yesJournal of Medical Sciences, 2017
Pannexin proteins comprise a family of channels whose sole function, to date, is the release of nucleotides (e.g., adenosine 5'-triphosphate [ATP] and uridine 5′-triphosphate [UTP]).
