Mathematical analysis of blood flow model through channels with flexible walls [PDF]

, 2011
A simplified mathematical model of blood flow through flexible arteries is developed and analyzed. The resulting system of non-linear, non-homogeneous PDE\u27s is analyzed numerically using the Richtmyer Lax-Wendroff method.

Vascular Calcification: Mechanisms, Models, and Therapies

iNew Medicine, EarlyView.
ABSTRACT Vascular calcification represents an active multifactorial process that mirrors several key features of skeletal bone mineralization. Clinically, it is characterized by diminished arterial compliance and increased arterial wall stiffness, both of which serve as independent predictors of significant adverse cardiovascular events.

Human coronary artery organ‐chip with circulating immune cells recapitulates anti‐inflammatory effect of pulsatile wall strain

Interdisciplinary Medicine, EarlyView.
A fully characterised organ‐on‐a‐chip model of the human coronary artery with endothelial and smooth muscle cells, plus circulating immune cells, created on the Emulate platform. The model successfully recapitulates the physiological effects of pulsatile vessel dilation on cell morphology and the localised inflammatory susceptibility to TNF‐α ...

Single‐Cell Profiling Identifies CLEC5A+ Macrophages as Key Drivers of Thoracic Aortic Aneurysm Via CCL5‐Mediated M1 Polarization

Journal of Clinical Laboratory Analysis, EarlyView.
Thoracic aortic aneurysm (TAA) is a life‐threatening cardiovascular disease with limited therapeutic options. Through single‐cell RNA sequencing of aortic tissues from healthy individuals and TAA patients (105,541 cells), we identified CLEC5A+macrophages as the predominant pathogenic cell population exhibiting the highest M1 polarization score.
