On the Estimation of Total Arterial Compliance from Aortic Pulse Wave Velocity

Nikolaos Stergiopoulos, Orestis Vardoulis

Total arterial compliance (C (T)) is a main determinant of cardiac afterload, left ventricular function and arterio-ventricular coupling. C (T) is physiologically more relevant than regional aortic stiffness. However, direct, in vivo, non-invasive, measure ...

Haemodynamic responses to temperature changes of human skeletal muscle studied by laser-Doppler flowmetry

Dimitri Nestor Alice Van De Ville, Jean-Noël Hyacinthe, Jonas Richiardi

Using a small, but very instructive experiment, it is demonstrated that laser-Doppler flowmetry (LDF) at large interoptode spacing represents a unique tool for new investigations of thermoregulatory processes modulating the blood flow of small muscle masse ...

Time course of flow-induced adaptation of carotid artery biomechanical properties, structure and zero-stress state in the arteriovenous shunt

Nikolaos Stergiopoulos

Numerous studies have provided evidence of diameter adaptation secondary to flow-overload. but with ambiguous findings vis a vis other morphological parameters and information on the biomechanical aspects of arterial adaptation is rather incomplete. We exa ...

Wall properties of the apolipoprotein E-deficient mouse aorta

Nikolaos Stergiopoulos, Aristotelis Agianniotis

Objectives: We quantified the dysfunction of the aortic wall, determined structural and elastic properties, and provided histological data of the thoracic aortas of apolipoprotein E (apoE)-deficient mice which are used as model of atherosclerosis. Methods: ...

Apparatus and methods for treating excess intraocular fluid

Nikolaos Stergiopoulos, Stéphane Bigler

An ocular drainage system is provided for treating diseases that produce elevated intraocular pressures, such as glaucoma, wherein the system includes an implantable device and an external control unit. The implantable device includes a non-invasively adju ...

Interfaces: How the Rupture Speed of Slip Fronts is Related to the Deformation Energy

Jean-François Molinari, David Simon Kammer, Vladislav Yastrebov

The transition from sticking to sliding of a frictional interface does not happen uniformly. The shear resistance of the interface is usually reached at a single point from which an interface rupture starts to propagate (Rubinstein et al., 2004). The repet ...

Intercellular calcium waves in primary cultured rat mesenteric smooth muscle cells are mediated by Connexin43

Jean-Jacques Meister, Jean-Louis Bény, Nadia Halidi

Intercellular Ca2+ wave propagation between vascular smooth muscle cells (SMCs) is associated with the propagation of contraction along the vessel. Here, we characterize the involvement of gap junctions (GJs) in Ca2+ wave propagation between SMCs at the ce ...

Extracellular matrix in angiogenesis: dynamic structures with translational potential

Jeffrey Alan Hubbell

The vascular network is an integral component of most organs. Beyond assuring an adequate supply of oxygen and nutrients for normal tissue function, vascular structures provide also a critical interface in the balance of tissue homoeostasis and immune func ...

Identification and Functional Response of "Interstitial Cells of Cajal"-like Cells from Rat Mesenteric Artery

Aurélie Formey de Saint Louvent

This thesis is a contribution to the field of interstitial cells of Cajal-like cells (ICC-LCs) in the vasculature. Indeed, cells with irregular shapes and numerous long thin filaments, morphologically similar to the gastrointestinal ICCs, have been observe ...
