Regeneration of the lizard heart after cryoinjury

Experimental Physiology, EarlyView.
Abstract Lizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regeneration in the leopard gecko (Eublepharis macularius) to fill the knowledge gap between traditional models of poikilothermic (zebrafish) and ...

Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

The Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...
