The interplay between dynamic regulation of ion‐channel gating and trafficking in cardiac arrhythmogenesis

The Journal of Physiology, EarlyView.
Abstract figure legend Cardiac cellular electrophysiology is modulated by multiple factors, including temperature, extracellular K+, heart rate/pacing frequency, and drugs. These modulators can have distinct effects on ion‐channel gating and transcription/trafficking over time.

Δ9 Tetrahydrocannabinol and cannabis extracts differentially improve adipoinsular dysfunction in diet‐induced obesity

The Journal of Physiology, EarlyView.
Abstract figure legend THC and extract administered to diet‐induced obese mice reduced body weight and fat storage. Extract, but not THC, improved glucose clearance by a mechanism that may include restoring adipoinsular function. Abstract Diet‐induced obesity (DIO) is associated with dysregulated adipoinsular axis and endocannabinoid system (eCBS ...

Mechanisms reducing parasympathetic activity in chronic hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Parasympathetic activity is reduced in chronic hypoxia, but the underlying mechanism(s) are unclear. Using β‐adrenergic blockade to isolate parasympathetic control of heart rate at sea level and after 9‐12 days at high altitude, we investigated whether (i) chemoreflex activation, (ii) increased pulmonary ventilation and/or (iii ...

Extracellular ionic concentration modulates arrhythmias in a simulated population of human ventricular myocytes with long QT syndrome type 3

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustrating the in silico study pipeline. A total of 50,000 virtual myocytes were generated, which were then filtered to 7093 myocytes that fit experimentally constrained biomarkers for physiological electrical and calcium behaviour under wild‐type conditions.

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

The Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.
