Role of macrophage scavenger receptors in atherosclerosis

Accumulating evidence indicates that atherosclerosis is a chronic inflammatory disease. The key innate immune cells that are involved in the pathogenesis of atherosclerosis are circulating monocytes and plaque macrophages. Complex interplay between immune ...

Two mutations in human BICC1 resulting in Wnt pathway hyperactivity associated with cystic renal dysplasia

Daniel Constam, Anne Grapin-Botton, Marine Marie Kraus

Bicaudal C homologue 1 (Bicc1) knockout in mice causes polycystic kidney disease and pancreas development defects, including a reduction in insulin-producing β-cells and ensuing diabetes. We therefore screened 137 patients with renal abnormalities or assoc ...

Pressure and Flow Wave Propagation in Patient-Specific Models of the Arterial Tree

Philippe Reymond

Blood flow in the arterial circulation induces hemodynamic forces that play an important role in various forms of vascular diseases. Temporal variation of the wall shear stress seems to play a significant role in atherogenesis and plaque stability. Flow in ...

Classification of magnetic resonance images from rabbit renal perfusion

Dominique Bonvin, Michael Amrhein, Pamandeep Singh Gujral

The feasibility of using chemometric techniques for the automatic detection of whether a rabbit kidney is pathological or not is studied. Sequential images of the kidney are acquired using Dynamic Contrast-Enhanced Magnetic Resonance Imaging with contrast ...

Regulation of arginase pathway in response to wall shear stress

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

Alterations of wall shear stress can predispose the endothelium to the development of atherosclerotic plaques. Ample evidence indicates that arginase expression and/or activity correlates with several risk factors for cardiovascular disease including ather ...

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 ...

Role of arginase pathway in response to shear stress: new potential therapeutic targets for atherosclerosis?

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, Veronica Gambillara

Introduction: Alterations of wall shear stress can predispose the endothelium to the development of atherosclerotic plaques. Ample evidence indicates that arginase expression and/or activity correlates with several risk factors for cardiovascular disease i ...

Pathological mineralization of cardiac valves: Causes and mechanism

Philippe Buffat, Elena Suvorova Buffat

Objective. Mechanism of calcification of cardiac valves was investigated through a comparative characterization of structure, morphology, and size of hydroxyapatite (HAP) crystals formed in mineral deposit on cardiac valves, bone tissue, and crystals synth ...

Arterial wall response to ex vivo exposure to oscillatory shear stress

Nikolaos Stergiopoulos, Paolo Silacci, Veronica Gambillara

The aim of this study was to analyze the arterial wall response to plaque-prone hemodynamic environments, known to occur mainly in areas of arterial trees such as bifurcations and branching points. In these areas, the vasculature is exposed to cyclically r ...

Effect of intimal shear and cyclic strech on arterial segments perfused in vitro

Veronica Gambillara

Hemodynamics have crucial role in the control of vascular tone, in the regulation of arterial remodeling, and in the production of mediators that maintain arterial function. Changes in hemodynamics forces induce profound alterations in vascular cell metabo ...
