Gap junctional and ephaptic coupling in cardiac electrical propagation: homocellular and heterocellular perspectives

The Journal of Physiology, EarlyView.
Abstract figure legend Intricate cellular electrical coupling networks in the heart. Various cell types couple the central cardiomyocyte through gap junctional contacts, with the exception of neurons. Whether ephaptic coupling (EpC) occurs in homocellular or heterocellular contexts beyond cardiomyocyte–cardiomyocyte interactions remains unclear ...

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

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

The 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).
