Prevention of Caval Collapse During Venous Drainage for CPB

A new plastic self-expanding Smartcanula (Smartcanula LLC, Lausanne, Switzerland) is designed for central insertion and prevention of caval collapse. The objective of our work is to assess the influence of the new design on atrial chatter. Caval collapse o ...

Jagged1 is the major regulator of notch-dependent cell fate in proximal airways

Freddy Radtke

Background: The Notch signaling pathway plays complex roles in developing lungs, including regulation of proximodistal fates, airway cell specification and differentiation. However, the specific Notch-mediated signals involved in lung development remain un ...

Characterizing the impact of minor cannula design modification

Julien Favre, Ludwig Von Segesser

Objective: Bench evaluation of the hydrodynamic behavior of venous cannulas is a valuable technique for the analysis of their performance during cardiopulmonary bypass (CPB). The aim of this study was to investigate the effect of the internal diameter of t ...

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: ...

Ventricle Equilibrium Position in Healthy and Normal Pressure Hydrocephalus Brains Using an Analytical Model

Jean-Marie Drezet, Bryn Andrew Martin, Kamal Shahim

The driving force that causes enlargement of the ventricles remains unclear in case of normal pressure hydrocephalus (NPH). Both healthy and NPH brain conditions are characterized by a low transparenchymal pressure drop, typically 1 mm Hg. The present pape ...

Pulse Wave Propagation in the Arterial Tree

Nikolaos Stergiopoulos

The beating heart creates blood pressure and flow pulsations that propagate as waves through the arterial tree that are reflected at transitions in arterial geometry and elasticity. Waves carry information about the matter in which they propagate. Therefor ...

Multi-objective optimization of regenerator placement using Constraint Programming

Sébastien Rumley, Christian Gaumier

In translucent optical networks, connections bypass most intermediate nodes transparently. However, their signal quality is affected by the traveled distance and/or the bypass operations. Hence, they might require optical-electrical-optical conversions at ...

Photodynamic therapy enhances liposomal doxorubicin distribution in tumors during isolated perfusion of rodent lungs

Hubert van den Bergh, Elodie Debefve, Yi Wang

Background: Photodynamic therapy (PDT) at low drug-light conditions can enhance the transport of intravenously injected macromolecular therapeutics through the tumor vasculature. Here we determined the impact of PDT on the distribution of liposomal doxorub ...

ECG-based prediction of atrial fibrillation development following coronary artery bypass grafting

Sinisa Sovilj

In patients undergoing coronary artery bypass grafting (CABG) surgery, post-operative atrial fibrillation (AF) occurs with a prevalence of up to 40%. The highest incidence is seen between the second and third day after the operation. Following cardiac surg ...

On the modelling and regulation of the cardiovascular system: Applications in 1D & 3D

Gaëlle Diserens

Baroreceptors are sensory cells that help the body to keep a constant aortic pressure by regulating cardiovascular parameters. The cardiovascular system can be modelled by several methods, comprising lumped parameter models which represent important parts ...
