[Mental disorders associated with acute COVID-19: clinical picture, therapy approaches].

Background: The purpose is to study the structure of clinical manifestations of mental disorders in the acute period of COVID-19 among patients, who were hospitalized with a new coronavirus infection and their relations with the severity of the immune response, to assess the efficacy and safety profile of the spectrum of used psychopharmacotherapy.

Material And Methods: A study was conducted of patients, hospitalized to the department of infectious diseases and repurposed for COVID-19 clinical departments with a diagnosis of COVID-19 (compliance with the criteria for ICD-10: U07.1) from September 2020 to March 2021.

Common Inflammatory Mechanisms in COVID-19 and Parkinson's Diseases: The Role of Microbiome, Pharmabiotics and Postbiotics in Their Prevention.

In the last decade, metagenomic studies have shown the key role of the gut microbiome in maintaining immune and neuroendocrine systems. Malfunction of the gut microbiome can induce inflammatory processes, oxidative stress, and cytokine storm. Dysfunction of the gut microbiome can be caused by short-term (virus infection and other infectious diseases) or long-term (environment, nutrition, and stress) factors.

DRIFT OF INFLUENA A(H3N2) VIRUS: BIOLOGICAL, ANTIGENIC AND GENETIC PROPERTIES IN EPIDEMIC SEASON 2016-2017 IN RUSSIA AND COUNTRIES OF THE NOTHERN HEMYSPHERE.

The article presents the features of the influenza virus circulation for the period from October 2016 to May 2017 in some territories of Russia collaborating with the D.I. Ivanovsky Institute of Virology, Federal State Budgetary Institution "N.

[The 2015-2016 epidemic season in Russia and the world: Circulation of influenza viruses, trends in incidence, clinical aspects, and treatment algorithm].

In the 2015-2016 epidemic season, there were dominant influenza A(H1N1)pdm09 strains (over 90%) among the circulating influenza viruses in most countries of the Northern Hemisphere and in Russia. A study of the antigenic properties of influenza A(H1N1)pdm09 strains revealed no differences in those of vaccine virus. Sequencing showed that there were amino acid substitutions in hemagglutinin (receptor binding and Sa sites) and in the genes encoding internal proteins (PA, NP, M1, and NS1).

Study of correlation between state and composition of lipid phase and change in erythrocytes structure under induction of oxidative processes.

We investigated human blood erythrocytes under oxidative stress in vitro and established a correlation between composition and state of lipids and changes in erythrocytes structure under induced oxidative stress. These changes may serve as an indicator of not only the erythrocyte state but of systemic processes that occur at the level of the whole organism, including various pathologies as well. We found that a pyrimidine derivative xymedon used in the present study is an effective inhibitor of oxidative processes.

Effect of hydrogen peroxide on ejection of cell nucleus from pigeon erythrocytes and state of membrane lipids.

The nuclei are ejected from the pigeon erythrocytes and apoptotic vesicles form in these cells in the presence of hydrogen peroxide. Hydrogen peroxide intensifies LPO processes and changes phospholipid content. The relative content of phosphatidylcholine, sphingomyelin, and phosphatidylserine decreased, while that of phosphatidylethanolamine and lisophosphatidylcholine increased.
