The nootropic neuroprotective peptide Semax (Met-Glu-His-Phe-Pro-Gly-Pro) has proved efficient in the therapy of brain stroke; however, the molecular mechanisms underlying its action remain obscure. Our genome-wide study was designed to investigate the response of the transcriptome of ischemized rat brain cortex tissues to the action of Semax in vivo.

The article presents a modern view of obesity as a chronic inflammation of adipose tissue. Obesity is accompanied by metabolic changes in lipid, protein, carbohydrate, mineral metabolism and disorders in the hormonal function of adipose tissue as an endo- and paracrine organ. At the moment, there are searched the biochemical markers of metabolic disorders of obesity. The obesity-related factors (hyperglycemia, increased lipid levels, insulin resistance, chronic inflammation, hyperleptinemia, endothelial dysfunction, impaired respiratory function of mitochondria, minerals and microelements deficiency) form and increase oxidative stress making it an integral component of the pathogenesis of obesity and possible complications. Given the important role of Q10 coenzyme in antioxidant tissue protection, the authors discuss the relationship of obesity and metabolic disorders to the endogenous levels of Q10 coenzyme and its possible use for pharmacological correction.
