Methane Studies

This article presents a state-of-the-art of atmospheric methane reconstruction based on ice-core studies. Starting with a biogeochemical overview of the methane cycle, it explains the processes of gas diffusion in firn and trapping in ice. It presents and ...

Arterial biomechanics after destruction of cytoskeleton by Cytochalasin D

Nikolaos Stergiopoulos, Sylvain Roy, Paolo Silacci, Tyler Nerton Thacher

Vascular smooth muscle is a major structural element of the arterial wall. We examined the effects of cytoskeleton destruction, after administration of Cytochalasin D, on the biomechanical properties of porcine common carotids. Compared to untreated, maxim ...

Vascular physiology

Sylvain Roy

This thesis aims at better understanding the role played by vascular smooth muscle cells (VSM) in the biomechanics of the arterial wall. Current models assume that under maximal vasodilation VSM carry no load, or the so-called "active stress" is zero. Biom ...

CO2 isotopes as tracers of firn air diffusion and age in an Arctic ice cap with summer melting, Devon Island, Canada

Jérôme Chappellaz

Atmospheric methane (CH4) records reconstructed from polar ice cores represent an integrated view on processes predominantly taking place in the terrestrial biogeosphere. Here, we present dual stable isotopic methane records [δ13CH4 and δD(CH4)] from four ...
