Potential health benefits of cold‐water immersion: the central role of PGC‐1α

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Lean Mass Gains, Cardiac Remodeling, and Muscle Oxidative Changes With High-Dose Salbutamol During Resistance Training: A Randomized Controlled Trial. [PDF]

open access: yesScand J Med Sci Sports
ABSTRACT Misuse of beta2‐agonists to promote leanness is increasingly reported among young men undertaking resistance training. However, preclinical models demonstrate adverse cardiac remodeling with high‐dose beta2‐agonist. We investigated effects of prolonged supratherapeutic treatment with salbutamol on body composition, cardiac morphology and ...

An age‐associated decline in the role of the sarcoplasmic reticulum and associated calcium‐handling proteins sets the pace for sinoatrial node function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Stable, responsive pacemaking in the sinoatrial node is driven by the activity of the funny current (membrane clock), interplay of calcium cycling and release from the sarcoendoplasmic reticulum with depolarising sodium‐calcium exchange current (calcium clock). With increasing age, key proteins associated with calcium cycling are

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

open access: yesThe 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

open access: yesThe 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 ...
