Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

The Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...

The sympathoregulatory region of the mouse rostral brainstem relies on both GABA and glycine to generate inhibitory currents

The Journal of Physiology, EarlyView.
Abstract figure legend Our study demonstrates that both GABA and glycine mediate inhibitory postsynaptic currents in the ventrolateral/ventromedial medulla (VLM/VMM) and increasing the activity of inhibitory synapses facilitates glycine release. We found that presympathetic VLM/VMM neurons receive glycinergic inputs, which release both glycine and GABA,

Electrophysiological characterization of pre‐adolescents born with intrauterine growth restriction: insights from clinical and computational data

The Journal of Physiology, EarlyView.
Abstract figure legend Depolarization and repolarization duration analysis was conducted in preadolescent groups with IUGR and controls using a 12‐lead ECG. Principal component analysis was applied over the 12‐lead ECGs to generate spatially transformed leads better suited for robust ECG fiducial points detection.

Insights from electromechanical simulations to assess omecamtiv mecarbil efficacy in heart failure

The Journal of Physiology, EarlyView.
Abstract figure legend Impact of Omecamtiv Mecarbil (OM) on in‐silico models of heart failure. A mathematical electromechanical model of human ventricular tissue is used to simulate the effects of OM in heart failure with reduced ejection fraction (HFrEF).
