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 ...

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

Haemodynamic‐energetic mechanism of sudden cardiac death in severe aortic stenosis: A modelling study

The Journal of Physiology, EarlyView.
Abstract figure legend A sudden decrease in total peripheral resistance (TPR), as observed during vasovagal syncope, leads to a reduction in aortic systolic pressure (AO pressure) and afterload. In healthy individuals, the consequent decrease in left ventricular systolic pressure (LV pressure) lowers stroke work and myocardial energy expenditure.

NAD replenishment restores mitochondrial function and thermogenesis in the brown adipose tissue of mice with obesity

The Journal of Physiology, EarlyView.
Abstract figure legend A high‐fat diet (HFD) induces brown adipose tissue (BAT) whitening, mitochondrial dysfunction (damaged cristae, fragmentation), reduced NAD+ levels and impaired thermogenesis, leading to lower energy expenditure and metabolic inflexibility.
