[On the relevance of examining the internal organs for the presence of diatom plankton after drowning at sea].

Objective: To establish the relevance of examining the internal organs for the presence of diatom plankton after drowning in the waters of the White Sea.

Material And Methods: We studied the biological material (fragments of lungs and kidneys) from the corpses of people found in the waters of the Kemskaya Bay and Onega Bay of the White Sea and waters from different areas of the White Sea for the presence of diatoms.

Results: In all cases of drowning in the waters of the White Sea (in the area of the city of Belomorsk and the Kem skerries), marine and freshwater diatoms were found in the lungs and kidneys of the deceased in quantities sufficient to diagnose death from drowning in water.

Review on the Use of Brain Computer Interface Rehabilitation Methods for Treating Mental and Neurological Conditions.

This review provides a comprehensive examination of recent developments in both neurofeedback and brain-computer interface (BCI) within the medical field and rehabilitation. By analyzing and comparing results obtained with various tools and techniques, we aim to offer a systematic understanding of BCI applications concerning different modalities of neurofeedback and input data utilized. Our primary objective is to address the existing gap in the area of meta-reviews, which provides a more comprehensive outlook on the field, allowing for the assessment of the current landscape and developments within the scope of BCI.

[Assessment of species diversity of anaerobic intestinal microbiota in children and adolescents with exogenous constitutional obesity].

The problem of the increasing obesity among children and adolescents is urgent. One of the most interesting and promising directions in this area is to study the correlation of individual microorganisms with the presence and absence of obesity. of the study was to assess the correlation between the isolation frequency of individual microorganisms and the presence of obesity in children and adolescents and to identify possible associations between different groups of microorganisms in obese patients.

Proteomic analysis of nontuberculous bacteria protein spectra as the element of subtyping of strains.

Background: For the present, matrix-assisted laser desorption/ionization-time-of-flight (MALDI-ToF) mass spectrometry is the fastest and the most correct method for species identification of microorganisms. Apart from species-level identification, it allows to use a variety of approaches for the analysis and comparison of protein spectra of microorganisms of the same species, which are isolated from a patient at various disease states, that can be used in routine microbiological practice in laboratories fitted with mass analyzers.

Methods: Two strains of Mycobacterium fortuitum and two strains of Mycobacterium peregrinum were isolated from sputum samples, which were obtained from patients with different clinical aspects of mycobacteriosis, whereat were reinoculated on the universal chromogenic culture medium "UriSelect 4.
