The Journal of Physiology, EarlyView.Abstract figure legend Blebbistatin reduces Ca2+ buffering in induced pluripotent stem cell‐derived atrial cardiomyocytes. Blebbistatin, a widely used excitation–contraction uncoupling agent, decreases calcium (Ca2+) buffer affinity (increased buffer dissociation constant), leading to elevated diastolic Ca2+ levels, increased sarcoplasmic reticulum Ca2+

The Journal of Physiology, EarlyView.Abstract figure legend The genetic inactivation of one Mcu allele leads to sex‐specific changes in neuronal function in adult mice, that is, the firing of action potentials and the relationship between cytosolic and mitochondrial Ca2+ levels. The ability to produce NAD(P)H by stimulated neural tissue is largely preserved in male mice but delayed in ...

Mathematical model of the zebrafish ventricular cardiomyocyte action potential and calcium transient
The Journal of Physiology, EarlyView.Abstract figure legend This study presents the development and validation of the first biophysically detailed computational model of the zebrafish ventricular action potential (AP). The model is based on a human cardiomyocyte framework and reparameterized using published and newly generated patch‐clamp recordings of zebrafish ionic currents.

The contribution of Kv7 channels to pregnant mouse and human myometrial contractility.
, 2011 Premature birth accounts for approximately 75% of neonatal mortality and morbidity in the developed world. Despite this, methods for identifying and treating women at risk of preterm labour are limited and many women still present in preterm labour ...

Frontiers in Cellular Neuroscience, 2018 Inwardly rectifying potassium channels (Kir) have been historically associated to several cardiovascular disorders. In particular, loss-of-function mutations in the Kir2.1 channel have been reported in cases affected by Andersen-Tawil syndrome while gain-

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.

, 2001 G protein–coupled inwardly rectifying potassium channels, GIRK/Kir3.x, are gated by the Gβγ subunits of the G protein. The molecular mechanism of gating was investigated by employing a novel yeast-based random mutagenesis approach that selected for ...

The Journal of Physiology, EarlyView.Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.
