The content of free fatty acids in mitochondrial and light mitochondrial fractions of the liver increased during 4-hour survival from 11 to 28 and from 8 to 43 nanomoles per mg protein, respectively. In the course of survival, the magnitude of the latent period of the Fe2+-induced chemiluminescence increased 2,5-4-fold in both mitochondrial fractions. With 2-hour survival the time of the chemiluminescence development was more prolonged and its intensity was reduced in the two fractions. The data obtained may indicate the increased antioxidative activity of the organelles during survival of the organ in situ.

Alzheimer's disease (AD), a prevalent neurodegenerative disorder, is characterized by mitochondrial dysfunction and immune dysregulation. This study is aimed at developing a risk prediction model for AD by integrating multi-omics data and exploring the interplay between mitochondrial energy metabolism-related genes (MEMRGs) and immune cell dynamics. We integrated four GEO datasets (GSE132903, GSE29378, GSE33000, GSE5281) for differential gene expression analysis, functional enrichment, and weighted gene co-expression network analysis (WGCNA).

Background: Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is a rare and progressive mitochondrial disorder characterized by multi-systemic involvement. This disease manifests in various clinical manifestations, with heart and kidney disorders being among the most common. Accurate diagnosis of MELAS often necessitates a range of complex investigations.

Compound K (CK), an active ingredient in ginseng, has anti-cancer, anti-inflammatory, and antioxidant properties. However, its effects on thermogenesis and mitochondrial dynamics in white adipose tissue (WAT) adipocytes are not well understood. This study explores CK's impact on thermogenesis and mitochondrial metabolism in cold-exposed mice and mouse stromal vascular fraction (SVF) cells.

Background: Atrial fibrillation (AF) persistence is associated with molecular remodeling that fuels electrical conduction abnormalities in atrial tissue. Previous research revealed DNA damage as a molecular driver of AF.
Objectives: This study sought to explore the diagnostic value of DNA damage in atrial tissue and blood samples as an indicator of the prevalence of electrical conduction abnormalities and stage of AF.
