Single-cell atlas reveals different immune environments between stable and vulnerable atherosclerotic plaques

open access: yesFrontiers in Immunology, 2023
IntroductionRegardless of the degree of stenosis, vulnerable plaque is an important cause of ischemic stroke and thrombotic complications. The changes of the immune microenvironment within plaques seem to be an important factor affecting the ...

Update of the CLRP eye plaque brachytherapy database for photon-emitting sources [PDF]

open access: yes, 2021
Purpose: To update and extend the Carleton Laboratory for Radiotherapy Physics (CLRP) Eye Plaque (EP) dosimetry database for low-energy photon-emitting brachytherapy sources using egs_brachy, an open-source EGSnrc application. The previous database, CLRP_EPv1, contained datasets for the Collaborative Ocular Melanoma Study (COMS) plaques (2008). The new

In Search of Vulnerable Plaque [PDF]

open access: yesCirculation: Cardiovascular Imaging, 2012
Between 1970 and 2010, the number of cardiovascular deaths per 100 000 persons in the United States has fallen from ≈450 to ≈125, a reduction >70%.1 This marked decline in cardiovascular mortality represents one of the true success stories of modern medicine.

Folate Receptor–Targeted Single-Photon Emission Computed Tomography/Computed Tomography to Detect Activated Macrophages in Atherosclerosis: Can It Distinguish Vulnerable from Stable Atherosclerotic Plaques?

open access: yesMolecular Imaging, 2014
The need for noninvasive imaging to distinguish stable from vulnerable atherosclerotic plaques is evident. Activated macrophages play a role in atherosclerosis and express folate receptor folate receptor β (FR-β).

Parallel Network with Channel Attention and Post-Processing for Carotid Arteries Vulnerable Plaque Segmentation in Ultrasound Images [PDF]

open access: yesarXiv, 2022
Carotid arteries vulnerable plaques are a crucial factor in the screening of atherosclerosis by ultrasound technique. However, the plaques are contaminated by various noises such as artifact, speckle noise, and manual segmentation may be time-consuming.

Identification of Heterogeneous Elastic Properties in Stenosed Arteries: a Numerical Plane Strain Study [PDF]

open access: yesComputer Methods in Biomechanics and Biomedical Engineering 14, 12 (2011) 1-10, 2011
Assessing the vulnerability of atherosclerotic plaques requires an accurate knowledge of the mechanical properties of the plaque constituents. It is possible to measure displacements in vivo inside a plaque using magnetic resonance imaging. An important issue is to solve the inverse problem that consists in estimating the elastic properties inside the ...

Quasi-static responses of marine mussel plaques attached to deformable wet substrates under directional tensions [PDF]

open access: yes, 2023
Quantifying the response of marine mussel plaque attachment on wet surfaces remains a significant challenge to a mechanistic understanding of plaque adhesion. Here, we developed a customised microscopy system combined with two-dimensional (2D) in-situ digital image correlation (DIC) to quantify the in-plane deformation of a deformable substrate that ...

Geographical predisposition influences on the distribution and tissue characterisation of eccentric coronary plaques in non-branching coronary arteries: cross-sectional study of coronary plaques analysed by intravascular ultrasound

open access: yesCardiovascular Ultrasound, 2016
Background We investigated the influence of geographical predisposition on the spatial distribution and composition of coronary plaques. Methods Thirty coronary arteries were evaluated.

Computed Tomography Biomarkers of Vulnerable Coronary Plaques

open access: yesJournal of Interdisciplinary Medicine, 2016
An unstable plaque has a high risk of thrombosis and at the same time for a fast progression of the stenosis degree. Also, “high-risk plaque” and “thrombosis-prone plaque” are used as synonym terms for characterization of a vulnerable plaque. The imaging

The Use of Biomarkers for the Early Detection of Vulnerable Atherosclerotic Plaques and Vulnerable Patients. A Review

open access: yesJournal of Cardiovascular Emergencies, 2016
Acute coronary syndromes represent the most severe consequences of atherosclerosis, most often triggered by the rupture of a coronary plaque, which, for various reasons, has become unstable.
