Coenzyme Q10 (CoQ10) plays a crucial role in facilitating electron transport during oxidative phosphorylation, thus contributing to cellular energy production. Statin treatment causes a decrease in CoQ10 levels in muscle tissue as well as in serum, which may contribute to the musculoskeletal side effects. Therefore, we aimed to assess the effect of newly initiated statin treatment on serum CoQ10 levels after acute ST-elevation myocardial infarction (STEMI) and the correlation of CoQ10 levels with key biomarkers of subclinical or clinically overt myopathy.

Article Synopsis
  • Autoimmune hepatitis (AIH) is a chronic liver disease treated with steroids and the thiopurine drug azathioprine (AZA), which is metabolized into active forms like 6-thioguanine (6-TG) and 6-methyl-mercaptopurine (6-MMP).
  • This study focused on creating a quick and effective ultra-high performance liquid chromatography-mass spectrometry (UHPLC-MS) method to analyze levels of 6-TG and 6-MMP in blood samples from AIH patients.
  • The new method was validated following EMA guidelines and proved to be accurate and precise for monitoring these important metabolites, facilitating better treatment management for patients.

Amino acids and biogenic amines are important components of food and beverages. In grape-derived products such as wine and wine vinegar, they can have different origins and can influence the odor and taste of the products. Their concentration is influenced by the grape variety, vintage, and winemaking process.

White adipocytes store lipids, have a large lipid droplet and few mitochondria. Brown and beige adipocytes, which produce heat, are characterized by high expression of uncoupling protein (UCP) 1, multilocular lipid droplets, and large amounts of mitochondria. The rs1421085 T-to-C single-nucleotide polymorphism (SNP) of the human gene interrupts a conserved motif for ARID5B repressor, resulting in adipocyte type shift from beige to white.
