Chronic cerebral hypoperfusion-induced myelin loss in normal-appearing white matter correlates with cognitive decline: insights from moyamoya disease. [PDF]

Alzheimers Dement (N Y)
Abstract INTRODUCTION Chronic cerebral hypoperfusion (CCH)‐induced white matter hyperintensities (WMHs) are a well‐established risk factor for cognitive impairment and dementia. While animal and post mortem studies suggest that myelin loss in normal‐appearing white matter (NAWM) precedes WMHs, in vivo evidence in human brain remains limited.

Embedded 3D‐Coaxial Bioprinting of Stenotic Brain Vessels with a Mechanically Enhanced Extracellular Matrix Bioink for Investigating Hemodynamic Force‐Induced Endothelial Responses

Advanced Functional Materials, EarlyView.
In this study, a physically enhanced vascular dECM bioink and used 3D‐coaxial bioprinting are developed to fabricate mature brain blood vessels for cerebral atherosclerosis research. This model demonstrates that vascular geometry‐induced hemodynamic changes trigger vascular inflammation, ensuring its potential for cerebrovascular research.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Bidirectional crusher gradient method to estimate the labeling efficiency of pseudo‐continuous arterial spin labeling MRI in mice

Magnetic Resonance in Medicine, EarlyView.
Abstract Purpose To develop an experimental method for measuring the labeling efficiency of pseudo‐continuous arterial spin labeling (pCASL) MRI in mice. Methods We propose a method using bidirectional crusher gradients to modulate vascular signals in the azygos pericallosal artery (azPA) of the mouse brain, applied with and without pCASL labeling.
