Frontiers 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]
, 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]
Circulation: 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.

Molecular 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]
arXiv, 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]
Computer 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]
, 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 ...

Computed Tomography Biomarkers of Vulnerable Coronary Plaques
Journal 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
