Intercellular calcium waves are associated with the propagation of vasomotion along arterial strips

Jean-Jacques Meister, Roger Sauser, Jean-Louis Bény, Michèle Koenigsberger, Dominique Seppey

Vasomotion consists of cyclic arterial diameter variations induced by synchronous contractions and relaxations of smooth muscle cells. However, the arteries do not contract simultaneously on macroscopic distances, and a propagation of the contraction can b ...

Mechanisms of Propagation of Intercellular Calcium Waves in Arterial Smooth Muscle Cells

Jean-Jacques Meister, Jean-Louis Bény, Michèle Koenigsberger, Dominique Seppey

In rat mesenteric arteries, smooth muscle cells exhibit intercellular calcium waves in response to local phenylephrine stimulation. These waves have a velocity of similar to 20 cells/s and a range of similar to 80 cells. We analyze these waves in a theoret ...

Metal Ion Implantation for the Fabrication of Stretchable Electrodes on Elastomers

Herbert Shea, Samuel Rosset, Muhamed Niklaus

We report on low-energy metal ion implantation by filtered cathodic vacuum arc to create highly deformable electrodes on polydimethylsiloxane (PDMS) membranes. Implantation leads to the creation of nanometer-size clusters in the first 50 nm below the surfa ...

Numerical Modeling of the Conjugate Heat Transfer Problem for Annular Laminar Film Condensation in Microchannels

John Richard Thome, Stefano Nebuloni

This paper presents numerical simulations of annular laminar film condensation heat transfer in micro-channels of different internal shapes. The model, which is based on a finite volume formulation of the Navier-Stokes and energy equations for the liquid p ...

Dictionary learning for the sparse modelling of atrial fibrillation in ECG signals

Pierre Vandergheynst, Jean-Marc Vesin, Rémi Gribonval

We propose a new method for ventricular cancellation and atrial modelling in the ECG of patients suffering from atrial fibrillation. Our method is based on dictionary learning. It extends both the average beat subtraction and the sparse source separation a ...

In-Vivo Measurements of Atrial Repolarization Alternans Based on Standard Pacemaker Technology

Jean-Marc Vesin, Florian Jousset, Etienne Pruvot

Introduction: It has been shown that repolarization alternans (Re-ALT), a beat-to-beat alternation in action potential duration, enhances dispersion of repolarization DOR above a critical heart rate and promotes susceptibility to ventricular arrhythmias. I ...

Electrical Conduction Mechanism in Chemically Derived Graphene Monolayers

Klaus Kern, Marko Burghard, Ravi Shankar Sundaram

We have performed a detailed study of the intrinsic electrical conduction process in individual monolayers of chemically reduced graphene oxide down to a temperature of 2 K. The observed conductance can be consistently interpreted in the framework of two-d ...

Adaptive Frequency Tracking on the ECG Used to Predict the Success of Electrical Cardioversion of Atrial Fibrillation

Jean-Marc Vesin, Mathieu Lemay, Yann Prudat, Frank Grégoire Jean de Morsier

One of the rhythm control strategies in atrial fibrillation management consists in the application of a brief single electrical shock to the atria. This electrical cardioversion does not always succeed, and the long-term success of this therapy is not suff ...
