Phylogenetic analysis of variants of the Puumala virus (Hantaviridae: ) circulating in the Saratov region.

Unlabelled: The objective is to determine the complete nucleotide sequence and conduct a phylogenetic analysis of genome variants of the Puumala virus isolated in the Saratov region.

Materials And Methods: The samples for the study were field material collected in the Gagarinsky (formerly Saratovsky), Engelssky, Novoburassky and Khvalynsky districts of the Saratov region in the period from 2019 to 2022. To specifically enrich the Puumala virus genome in the samples, were used PCR and developed a specific primer panel.

[Drug-induced liver injury: diagnosis of exclusion].

Drug-induced liver injury (DILI) is a relevant issue in clinical practice and is still a diagnosis of exclusion. Despite the low incidence in the general population, DILI is the cause of most cases of acute hepatic injury and has a mortality rate of up to 50%. Despite many reports in the medical literature about the DILI mechanisms, a clear causal relationship between them, drugs, and risk factors has not been established.

[Obstructive sleep apnea syndrome in children as a risk of cardiovascular pathology development].

Objective: Our aim was to examine the predictors of cardiovascular disorders in children affected by obstructive sleep apnea syndrome (OSAS) based on the results of polysomnography and continuous monitoring of blood glycose.

Methods: Before the examination, parents filled in questionnaires concerning their children sleep quality. The procedure was followed by the study of the sleep by means of polysomnography (Embla s 7000, USA).

[Proteomic methods of protein separation and analysis].

The review briefly presents principles and stages of execution of such highly effective methods of protein separation as capillary, 2D gel-electrophoresis, liquid chromatography, the possibility of their successful combination with tandem mass-spectrometry and application in various fields of proteomics. The main problems of proteomic analysis as well as ways of solving by using mass-spectrometry are examined. 2 main approaches during protein identification are described in the review, characteristics and possibilities of various top-down and bottom-up proteomic analytical programs are provided.
