Examination of carnosine in patients with diabetes mellitus type I, showed that the plasma levels of carnitine were non significantly increased compared to the levels in healthy population, while the levels in red cells were decreased Lowered levels of carnosine in red cells could point out similar deficit in other cells. Due to low levels in cells carnosine is less available for metabolic processes, like antioxidant reactions and its participation in antioxidants defense reactions is limited non-enzymatic glycosylation of proteins. Therefore it should be supplemented. (Tab. 1, Fig. 1, Ref. 15.)

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.

Introduction: Bone marrow-derived mesenchymal stem cell-derived extracellular vesicles (BMSC-EVs) are widely used for therapeutic purposes in preclinical studies. However, their utility in treating diabetes-associated atherosclerosis remains largely unexplored. Here, we aimed to characterize BMSC-EV-mediated regulation of autophagy and macrophage polarization.

The Bartonella genus of bacteria encompasses ubiquitous species, some of which are pathogenic in humans and animals. Bartonella henselae, the causative agent of Cat Scratch disease, is responsible for a large portion of human Bartonella infections. These bacteria can grow outside of cells, replicate in erythrocytes and invade endothelial and monocytic cells.
