Experimental Physiology, EarlyView.Abstract Endothelial dysfunction drives obesity‐related complications. Doppler ultrasound measurement of blood flow during 1‐min passive leg movements (PLM) is a valuable non‐invasive tool for assessing endothelial function and nitric oxide (NO)‐mediated vasodilation.

Experimental Physiology, EarlyView.Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

Free‐Breathing, 3D Cardiac Magnetic Resonance Elastography for Myocardial Stiffness Mapping
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2356-2369, April 2026.ABSTRACT Purpose Magnetic resonance elastography (MRE) of the heart has predominantly utilized breath‐held acquisitions with limited anatomic coverage. This work investigates the feasibility of 3D, free‐breathing cardiac MRE. Methods A 3D hybrid radial and EPI acquisition is utilized and combined with retrospective binning of k‐space via physiologic ...

Modelling and simulation of hydrogen production via natural gas plasma pyrolysis
The Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1174-1189, March 2026.Methane pyrolysis simulation model. Abstract Plasma pyrolysis is a cutting‐edge technology that produces hydrogen and solid carbon from methane without emitting carbon dioxide. In this study, we developed a process simulation model in Aspen HYSYS to analyze the behaviour of this technology at the commercial scale.
