Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Computational modelling of myocardial metabolism in patients with advanced heart failure

open access: yesEuropean Journal of Heart Failure, EarlyView.
LV, left ventricular; LVAD, left ventricular assist device; LVEF, left ventricular ejection fraction. Abstract Aims Perturbations of myocardial metabolism and energy depletion are well‐established hallmarks of heart failure (HF), yet methods for their systematic assessment remain limited in humans.

Epigenotoxicity: Decoding the epigenetic imprints of genotoxic agents and their implications for regulatory genetic toxicology

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Regulatory genetic toxicology focuses on DNA damage and subsequent gene mutations. However, genotoxic agents can also affect epigenetic marks, and incorporation of epigenetic data into the regulatory framework may thus enhance the accuracy of risk assessment.

Temporal metabolomic fingerprinting identifies adenine as a novel biomarker for early detection of Escherichia coli infection in broiler chickens

open access: yesScientific Reports
Avian pathogenic Escherichia coli causes septicemia in broiler chickens leading to high mortality and economic losses. Current diagnostic methods, such as serology and culture, cannot detect infections during early asymptomatic stages.
