Products of the decomposition and oxidation of rifampicin were obtained; characterized by spectrophotometry, TLC, and HPLC; and identified by mass spectrometry. The stability of the drug in aqueous solutions and in liposomal compositions at 4 and 25°C was evaluated. The main product of rifampicin decomposition on storage is 3-formylrifampicin SV. The antimicrobial activity of the antibiotic in liposomal compositions is the same as that in aqueous solutions and is well retained on storage.
The article provides an overview of key studies on vagus nerve stimulation. The vagus nerve stimulation method affects the nerve fibers of the internal and external nerve plexuses, enhancing the parasympathetic effect. The positive therapeutic effect has been achieved in various experimental and clinical studies on the treatment of neurological and cardiac diseases, metabolic syndrome, and obesity. It has been shown that vagus nerve stimulation reduces epileptic seizures frequency, cardiac arrhythmias, and is prognostically favorable for the treatment of ischemia and reperfusion injury of the myocardium. Recent studies have examined the inflammatory reflex involved in the pathogenesis of obesity. The role of bioelectronic vagus nerve stimulation is being actively investigated for the treatment of obesity and metabolic syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
