Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, EarlyView.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

The Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

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.

Angiotensin‐converting enzyme and exercise adaptations: Genetic variability, pharmacological modulation and future directions

The Journal of Physiology, EarlyView.
Abstract figure legend ACE I/D genotype, enzyme activity and integrated physiological adaptations. Upper panel: Conceptual framework linking the ACE I/D polymorphism (left) with circulating/tissue ACE activity (centre; violin plots based on hypothetical data for illustration) and strength/power versus endurance phenotypes (right).

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).
