Intercalated disk structure, tissue heterogeneity and ion channel distribution modulate conduction and local calcium influx

The Journal of Physiology, EarlyView.
Abstract figure legend A, three‐dimensional representation of cardiac intercalated disk, reduced to a 100‐partition, computationally efficient network representation. B, ion dynamics within intercalated disk extracellular cleft space. C, rapid pacing leads to localized conduction block in tissue with regions of perturbed intercalated disk (ID ...

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

The 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

Gas exchange and pulmonary stress variations during SCUBA and breath‐hold diving in open seawater

The Journal of Physiology, EarlyView.
Abstract figure legend Healthy, trained divers were studied before, during and after diving in open seawater with different techniques. SCUBA divers (diving to 15 or 40 m with air; cycling at depth) and breath‐hold divers (BHDs; sled‐assisted dives to 15, 25 or 40 m) underwent underwater and surface arterial blood gas (ABG) sampling.

Panoramic voltage‐sensitive optical mapping of contracting hearts using cooperative multiview motion tracking with 12 cameras

The Journal of Physiology, EarlyView.
Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).
