A simplified model for red cell dynamics in small blood vessels

open access: yes, 1998
A simple mechanism for the confinement of red cells in the middle of narrow blood vessels is proposed. In the presence of a quadratic shear, red cells deform in such a way to loose fore-aft symmetry and to achieve a fixed orientation with respect to the ...

High‐Resolution MRI Revealed Different Etiology‐Specific Associations With Cerebral Infarction in Adult Moyamoya Vasculopathy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.

In vivo super-resolution photoacoustic computed tomography by localization of single dyed droplets [PDF]

open access: yes, 2020
The spatial resolution of photoacoustic (PA) computed tomography (PACT) is limited by acoustic diffraction. Here, we report in vivo superresolution PACT, which breaks the acoustic diffraction limit by localizing the centers of single dyed droplets.

Choroid Plexus Enlargement and USPIO‐Based Inflammatory Feature in Cerebral Small Vessel Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The choroid plexus (CP) is a key component of the blood–cerebrospinal fluid barrier (BCSFB), but its mechanism of action in cerebral small vessel disease (CSVD) remains unclear. This study investigated CP volume (CPV) alterations and their association with conventional imaging markers in CSVD and explored the underlying role of ...

Interstitial Cells of Blood Vessels

open access: yesThe Scientific World Journal, 2010
Blood vessels are made up of several distinct cell types. Although it was originally thought that the tunica media of blood vessels was composed of a homogeneous population of fully differentiated smooth muscle cells, more recent data suggest the ...

White Matter Hyperintensity Burden and Short‐Interval Change Associated With Sleep Apnoea in the UK Biobank

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Purpose White matter hyperintensities (WMH) are a core neuroimaging marker of cerebral small vessel disease (CSVD). Sleep apnoea (SA) is a recognized vascular risk factor, but its associations with regional WMH burden, short‐interval WMH change and cognitive performance in population‐based cohorts remain incompletely defined. We

Injectable sustained-release danshensu sodium-loaded nanoparticle hydrogel targets macrophages to improve myocardial microenvironment for myocardial infarction treatment

open access: yesBioactive Materials
Myocardial infarction (MI) induces cardiomyocyte necrosis, inflammation, fibrosis, and ventricular remodeling, leading to heart failure. To address this, we developed an intelligent cardiac patch, SMM@Gel, composed of a reactive oxygen species (ROS ...

Cardiovascular remodelling in patients with pre-dialysis chronic kidney disease and renal transplant recipients [PDF]

open access: yesMedicinski Glasnik, 2019
Aim To evaluate the relationship between cardiovascular remodelling and glomerular filtration rate (eGFR) in pre-dialysis chronic kidney disease (CKD) patients without cardiovascular diseases (CVD) and in renal transplant recipients (RTR).
