Abstract
The phenomenon of déjà vu (DV) is of interest, occurring in 97% of healthy individuals, while DV can be a manifestation of a number of pathologies, such as Charles Bonnet syndrome, depression, schizophrenia, or temporal lobe epilepsy. Most cases of DV type epiphenomena are associated with hippocampal sclerosis, while up to 90% of patients with mesial temporal sclerosis are drug resistant. Despite the success of pharmacotherapy, the frequency of «uncontrolled» epilepsy in industrialized countries that adhere to modern standards of treatment is from 30 to 40%, and this percentage is higher among patients with symptomatic and cryptogenic forms than among patients with idiopathic epilepsy (respectively: 40% and 26%). In turn, when studying the DV phenomenon and choosing a therapy strategy, it is necessary to establish its origin, determine its clinical significance (whether it is initially pathological or not), and the need for treatment. During the analysis of exome data, a search was made for substitutions in genes associated with arteriovenous malformations, both with autosomal dominant and autosomal recessive types of inheritance. The genes KRIT1, RASA1, IL6, FAM58A, GLML, EPHB4, CCM2, and ELMO2 were analyzed especially carefully. The analysis of genetic data is of great importance in the aspect of preventing cerebrovascular accidents, at the same time, in order to obtain reliable and significant results, in addition to time and financial costs, examination of relatives is also required. Meanwhile, this fact does not mean that every patient needs to conduct a genetic study. The paper presents detailed instructions for supplementing anamnestic information, as well as the results of personalized instrumental and laboratory diagnostics, which made it possible to carry out timely correction of therapy and achieve a prolonged positive effect.

Abstract
Microorganisms and their hosts communicate with each other by secreting numerous components. This cross-kingdom cell-to-cell signaling involves proteins and small molecules, such as metabolites. These compounds can be secreted across the membrane via numerous transporters and may also be packaged in outer membrane vesicles (OMVs). Among the secreted components, volatile compounds (VOCs) are of particular interest, including butyrate and propionate, which have proven effects on intestinal, immune, and stem cells. Besides short fatty acids, other groups of volatile compounds can be either freely secreted or contained in OMVs. As vesicles might extend their activity far beyond the gastrointestinal tract, study of their cargo, including VOCs, is even more pertinent. This paper is devoted to the VOCs secretome of the Bacteroides genus. Although these bacteria are highly presented in the intestinal microbiota and are known to influence human physiology, their volatile secretome has been studied relatively poorly. The 16 most well-represented Bacteroides species were cultivated; their OMVs were isolated and characterized by NTA and TEM to determine particle morphology and their concentration. In order to analyze the VOCs secretome, we propose a headspace extraction with GC-MS analysis as a new tool for sample preparation and analysis of volatile compounds in culture media and isolated bacterial OMVs. A wide range of released VOCs, both previously characterized and newly described, have been revealed in media after cultivation. We identified more than 60 components of the volatile metabolome in bacterial media, including fatty acids, amino acids, and phenol derivatives, aldehydes and other components. We found active butyrate and indol producers among the analyzed Bacteroides species. For a number of Bacteroides species, OMVs have been isolated and characterized here for the first time as well as volatile compounds analysis in OMVs. We observed a completely different distribution of VOC in vesicles compared to the bacterial media for all analyzed Bacteroides species, including almost complete absence of fatty acids in vesicles. This article provides a comprehensive analysis of the VOCs secreted by Bacteroides species and explores new perspectives in the study of bacterial secretomes in relation the intercellular communication.

Abstract
Primary cardiac channelopathies are a group of diseases wherein the role of DNA testing in aiding diagnosis and treatment-based decision-making is gaining increasing attention. However, in some cases, evaluating the pathogenicity of new variants is still challenging. We report an accurate multistage assessment of a rare genetic variant in the SCN5A gene using next-generation sequencing (NGS) techniques and Sanger sequencing. Female sportsman (14 years old) underwent genetic counseling and DNA testing due to QT interval prolongation registered during ECG Holter monitoring. Genetic testing of the proband was performed in two independent laboratories. Primary DNA testing was performed by WES using the Ion ProtonTM System. Target panel sequencing of 11 genes was performed using PGM Ion Torrent. Search for variants in non-canonical and canonical exons 6 was performed by Sanger sequencing. The cascade familial screening and control re-sequencing were provided for proband with identified genetic variant p.S216L (g.38655290G>A, NM_198056.2:c.647C>T, and rs41276525) in the canonical exon 6 of the SCN5A gene after receiving data from another laboratory. Control Sanger and NGS sequencing revealed the absence p.S216L in the canonical exon 6 and confirmed the presence of p.S216L (g.38655522G>A, c.647C>T, and rs201002736) in the non-canonical exon 6 of the SCN5A gene. The identified variant was re-interpreted. The non-canonical transcripts of the exon 6 of the SCN5A gene is poorly represented in cardiac tissue (gnomAD). The detected variant was found in proband's healthy mother. The correct interpretation of genetic data requires close cooperation between clinicians and researchers. It can help to avoid financial costs and stress for proband's and families.

Abstract
Investigations performed by the authors show that normalization of the mechanisms of vegetative regulation of arterial pressure and cerebral vessels tonicity in young patients with sympathico-tonic vegetative dystonia can be achieved by combined use of constant magnetic field (magnetic induction 60 mTl, penetration 10 mm, area 1.5 cm2) and monochromatic electromagnetic wave (length 0.47 mcm, frequency 6 x 10(14) Hz, penetration 1.5 mm and light spot 7 mm) which are directed to a biologically active point C7 shen-men from both sides simultaneously for 3 min, at 11 a.m. to 13 p.m. once a day, for 10 days.

Abstract
Permanent magnetic field was applied by placing two magnetic discs (induction 60 mT) in the projection of great arteries on both sides symmetrically. The treatment was given to hypertensive patients with vegetovascular asthenia. A course of such magnetic treatment affects pathogenetic mechanisms of vegetative disorders due to the ability of permanent magnetic field to restore vegetative homeostasis, normalize sympathicotony and vegetative regulation.
