[Intestinal microbiota and chronic heart failure: association and targets of influence of therapy.].

The increasing prevalence of chronic heart failure (CHF) among older people is a global problem. Despite the success of treatment, the mortality rate of these patients remains high, resulting in the need to search for new mechanisms of the development and progression of cardiovascular system pathologies, as well as to develop innovative branches of therapy. Considerable recent interest has been directed towards studying changes in the composition of the intestinal microbiota in people with age, its role in development, as well as potential directions for the prevention of cardiovascular diseases and their complications.

[Features of gastroesophageal reflux disease in elderly patients (literature review).].

In recent years, there has been an increase in the incidence of gastroesophageal reflux disease (GERD) in the elderly not only in our country, but also worldwide. In this regard, the issues of early diagnosis and development of an individualized approach to the treatment of this disease are of particular relevance. When addressing these issues, it is necessary to take into account a number of features in patients of older age groups, which include polymorbidity and polypharmacotherapy in combination with anatomical, physiological and functional age-related changes.

Experimental modeling of preclinical and clinical stages of Parkinson's disease.

Degeneration of dopaminergic (DAergic) neurons of the nigrostriatal system is the key stage in the pathogenesis of Parkinson's disease. The first symptoms of this disease are observed after degeneration of 70-80% neurons, which occurs over 20-30 years. The clinical stage of Parkinson's disease begins after this period.

[Possible role of serotonin 5-HT2 receptors in mechanism of afobazole anxiolytic action: neurochemical study of inter-line differences in mice].

Effects of separate and combined introduction of afobazole and SB-200646A (highly selective 5-HT2B/2C receptor antagonist) on the content of monoamines and their metabolites in brain structures of mice of C57/Bl/6 and BALB/C lines have been studied using neurochemical methods and high-performance liquid chromatography (HPLC). Afobazole (5 mg/kg, i.p.

[Levetiracetam modifies the pattern of audiogenic locomotive response in Wistar and Krushinsky-Molodkina strain rats].

The novel antiepileptic drug levetiracetam (keppra, 80 mg/kg, i.p.) produces a pronounced anticonvulsant effect on all parameters of the audiogenic locomotion response in Wistar rats, leading to the prevention of acoustic seizures approximately in 50% animals.
