Sub-micrometer morphology of human atherosclerotic plaque revealed by synchrotron radiation-based mu CT-A comparison with histology

Histology is a long standing and well-established gold standard for pathological characterizations. In recent years however, synchrotron radiation-based micro-computed tomography (SR mu CT) has become a tool for extending the imaging of two-dimensional thi ...

Metabolic fingerprints discriminating severity of acute ischemia using in vivo high-field H-1 magnetic resonance spectroscopy

Hongxia Lei, Lara Buscemi Estefanell

Despite the improving imaging techniques, it remains challenging to produce magnetic resonance (MR) imaging fingerprints depicting severity of acute ischemia. The aim of this study was to evaluate the potential of the overall high-field H-1 MR Spectroscopy ...

Influence of Vascular Variant of the Posterior Cerebral Artery (PCA) on Cerebral Blood Flow, Vascular Response to CO2 and Static Functional Connectivity

Dimitri Nestor Alice Van De Ville, Maria Giulia Preti, Daniela Maria Zöller, Kirsten Emmert

Introduction The fetal origin of the posterior cerebral artery (fPCA) is a frequent vascular variant in 11-29% of the population. For the fPCA, blood flow in the PCA originates from the anterior instead of the posterior circulation. We tested whether this ...

Segmentation and Grid Generation for Numerical Simulations of VAD Connections with Patientspecific Data

Alfio Quarteroni, Simone Deparis, Elena Faggiano, Jean Bonnemain, Ludwig Von Segesser

Objectives: We are interested in the numerical simulation of the anastomotic region comprised between outflow canula of LVAD and the aorta. Segmentation, geometry reconstruction and grid generation from patient specific data remain an issue because of the ...

Plaque-prone hemodynamics impair endothelial function in pig carotid arteries

Nikolaos Stergiopoulos, Sylvain Roy, Paolo Silacci, Veronica Gambillara

Hemodynamic forces play an active role in vascular pathologies, particularly in relation to the localization of atherosclerotic lesions. It has been established that low shear stress combined with cyclic reversal of flow direction (oscillatory shear stress ...

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 ...

Inhibition of thrombosis and intimal thickening by in situ photopolymerization of thin hydrogel barriers

Jeffrey Alan Hubbell

Thin hydrogel barriers formed on the inner surface of injured arteries by interfacial photopolymerization dramatically reduced thrombosis and intimal thickening in rat and rabbit models of vascular injury. This polymerization technique allowed the synthesi ...
