Impact of disturbed flow and arterial stiffening on mechanotransduction in endothelial cells
Biomech Model Mechanobiol. 2023 Sep 14. doi: 10.1007/s10237-023-01743-0. Online ahead of print.ABSTRACTDisturbed flow promotes progression of atherosclerosis at particular regions of arteries where the recent studies show the arterial wall becomes stiffer. Objective of this study is to show how mechanotransduction in subcellular organelles of endothelial cells (ECs) will alter with changes in blood flow profiles applied on ECs surface and mechanical properties of arterial wall where ECs are attached to. We will examine the exposure of ECs to atherogenic flow profiles (disturbed flow) and non-atherogenic flow profiles (pure...

Biomechanical characterization of tissue types in murine dissecting aneurysms based on histology and 4D ultrasound-derived strain
Biomech Model Mechanobiol. 2023 Sep 14. doi: 10.1007/s10237-023-01759-6. Online ahead of print.ABSTRACTAbdominal aortic aneurysm disease is the local enlargement of the aorta, typically in the infrarenal section, causing up to 200,000 deaths/year. In vivo information to characterize the individual elastic properties of the aneurysm wall in terms of rupture risk is lacking. We used a method that combines 4D ultrasound and direct deformation estimation to compute in vivo 3D Green-Lagrange strain in murine angiotensin II-induced dissecting aortic aneurysms, a commonly used mouse model. After euthanasia, histological staining ...

A computational investigation of occlusive arterial thrombosis
Biomech Model Mechanobiol. 2023 Sep 13. doi: 10.1007/s10237-023-01765-8. Online ahead of print.ABSTRACTThe generation of occlusive thrombi in stenotic arteries involves the rapid deposition of millions of circulating platelets under high shear flow. The process is mediated by the formation of molecular bonds of several distinct types between platelets; the bonds capture the moving platelets and stabilize the growing thrombi under flow. We investigated the mechanisms behind occlusive thrombosis in arteries with a two-phase continuum model. The model explicitly tracks the formation and rupture of the two types of interplatel...
