Computational model of haemodynamics during atrial fibrillation

The Journal of Physiology, EarlyView.
Abstract figure legend We developed a simplified computational model that replicates patient‐specific haemodynamics during both normal sinus rhythm and atrial fibrillation (AF). Our computational model comprises: (1) an electrical subsystem that generates unco‐ordinated atrial and irregular ventricular activation times characteristic of AF and (2) a ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Insights from animal models: Dissecting the independent roles of oxygen and nutrients in the fetal origins of cardiovascular disease

The Journal of Physiology, EarlyView.
Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

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

The 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 ...

The descending limb of the sarcomere length-force relation in single muscle fibres of the frog.

, 1985
Single muscle fibres, isolated from the tibialis anterior muscle of the frog, were used to study intersarcomere dynamics during muscle-isometric (fixed-end) tetani at long sarcomere lengths.
