Arterial remodeling in response to increased blood flow using a constituent-based model

Nikolaos Stergiopoulos, Alkiviadis Tsamis

Previous theoretical models of arterial remodeling in response to changes in blood flow were based on the assumption that material properties of the arterial wall remain unchanged during the remodeling process. According to experimental findings, however, ...

RC time constant of single lung equals that of both lungs together: a study in chronic thromboembolic pulmonary hypertension

Nikolaos Stergiopoulos, Nico Westerhof

The product of resistance, R, and compliance, C (RC time), of the entire pulmonary circulation is constant. It is unknown if this constancy holds for individual lungs. We determined R and C in individual lungs in chronic thromboembolic pulmonary hypertensi ...

Autonomous effects of shear stress and cyclic circumferential stretch regarding endothelial dysfunction and oxidative stress: an ex vivo arterial model

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Paolo Silacci, Tyler Nerton Thacher

Cyclic circumferential stretch and shear stress caused by pulsatile blood flow work in concert, yet are very different stimuli capable of independently mediating endothelial function by modulating eNOS expression, oxidative stress (via production of supero ...

Effects of reduced cyclic stretch on vascular smooth muscle cell function of pig carotids perfused ex vivo

Nikolaos Stergiopoulos, Paolo Silacci, Tyler Nerton Thacher, Veronica Gambillara

With advancing age arteries stiffen, reducing arterial compliance and leading to the development of systolic hypertension and to a substantial increase in pulse pressure. An augmented pulse pressure can be a predictor of the development of hypertension, wh ...

Using forward calculations of the magnetic field perturbation due to a realistic vascular model to explore the BOLD effect

José Pedro Rebelo Ferreira Marques

This paper assesses the reliability of the infinite cylinder model used previously in the literature to simulate blood oxygenation level dependent (BOLD) signal changes. A three-dimensional finite element method was applied to a realistic model of the cort ...

Age-Hardening Response of Replicated Microcellular Al-4.5%Cu

Andreas Mortensen, Yves Conde

We study the response to age hardening of Al-4.5%Cu replicated foams with 75 and 400 pm cell sizes and with varying relative densities. The 400 mu m cell size foams have a similar behavior to the bulk alloy, whereas the 75 pm cell size foams with relative ...

Oscillatory shear stress and reduced compliance impair vascular functions

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Paolo Silacci, Tyler Nerton Thacher, Veronica Gambillara

Shear stress has been shown to influence endothelial cell gene expression and morphology. In particular, low and bi-directional shear stress, mimicking conditions at plaque-prone areas, down-regulates the expression of several atheroprotective genes, and u ...

Effect of elastin degradation on carotid wall mechanics as assessed by a constituent-based biomechanical model

Nikolaos Stergiopoulos, Sylvain Roy, Luca Augsburger, Edouard Fonck, Gilles Prod'Hom

Arteries display a nonlinear anisotropic behavior dictated by the elastic properties and structural arrangement of its main constituents, elastin, collagen, and vascular smooth muscle. Elastin provides for structural integrity and for the compliance of the ...

Structural strain energy function applied to the ageing of the human aorta

Nikolaos Stergiopoulos, Martin Zulliger

Stiffening of the aorta with progressing age leads to decrease of aortic compliance and thus to an increase of pulse pressure amplitude. Using a strain energy function (SEF) which takes into account the composition of the arterial wall, we have studied the ...
