Heterogeneous domain decomposition methods for fluid-structure interaction problems

Alfio Quarteroni, Simone Deparis, Gilles Fourestey, Marco Discacciati

In this note, we propose Steklov-Poincaré iterative algorithms (mutuated from the analogy with heterogeneous domain decomposition) to solve fluidstructure interaction problems. Although our framework is very general, the driving application is concerned wi ...

Combination therapy using aspirin-enhanced photodynamic selective drug delivery

Hubert van den Bergh, Elodie Debefve

In photodynamic therapy (PDT), excitation of a drug by light leads to a cascade of biochemical processes that can cause closure of blood vessels. It has been observed clinically that significant short-term leakage from the irradiated vasculature can occur ...

Vectorial reconstruction of retinal blood flow in three dimensions measured with high resolution resonant Doppler Fourier domain optical coherence tomography

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely, Cédric Blatter

Resonant Doppler Fourier domain optical coherence tomography (FDOCT) is a functional imaging tool for extracting tissue flow. The method is based on the effect of interference fringe blurring in spectrometer-based FDOCT, where the path difference between s ...

Shear stress and cyclic circumferential stretch, but not pressure, alter connexin43 expression in endothelial cells

Nikolaos Stergiopoulos, Paolo Silacci

Hemodynamic forces play a critical role in atherogenesis, as evidenced by the focal pattern of development of atherosclerotic lesions. Whereas disturbed flow in the branches and curved regions of large arteries is proatherogenic, laminar flow in the straig ...

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 ...

Arterial pressure transfer characteristics: effects of travel time

Nikolaos Stergiopoulos, Nico Westerhof

We investigated the quantitative contribution of all local conduit arterial, blood, and distal load properties to the pressure transfer function from brachial artery to aorta. The model was based on anatomical data, Young's modulus, wall viscosity, blood v ...

Complex Systems in Biomedicine

Alfio Quarteroni, Luca Formaggia

Mathematical modeling of human physiopathology is a tremendously ambitious task. It encompasses the modeling of most diverse compartments such as the cardiovascular, respiratory, skeletal and nervous systems, as well as the mechanical and biochemical inter ...

The non-circular shape of FloWatch®-PAB prevents the need for pulmonary artery reconstruction after banding

Alfio Quarteroni, Paolo Zunino, Ludwig Von Segesser

To evaluate the differences between non-circular shape of FloWatch®-PAB and conventional pulmonary artery (PA) banding. Methods: Geometrical analysis. Conventional banding and FloWatch®-PAB perimeters were plotted against cross-sections. Computational flui ...
