The parasite of nine-spine sticklebacks, the Neoechinorhynchus beringianus, was found in the intestines of the broad whitefish caught in the Buyunda River, the Kolyma tributary. The morphometric parameters of the found specimen and individuals of the same species from the population existing in the lower reaches of the Kolyma River were compared. The possible conditions of the host species infection with a non-indigenous parasite and the variants of the acanthocephalan settlement in the river basin are considered.

The importance of studying the microelement composition of soils and vegetation in the Northern territories is due to the role of microelements in soil formation under cryolithozone conditions, and secondly, the influence of the microelement background of plants on the physiological functions of animals and humans. At the same time, heavy metals deserve special attention as they pose a threat to all living organisms due to their ability to accumulate. The article presents data on the content of heavy metals in the aboveground parts of meadow grasses growing under cryolithozone conditions - in the Khangalassky district, located in the Central Yakut biogeochemical province. Atomic absorption spectral analysis showed that the content of heavy metals - cadmium and lead - in the aboveground parts of the studied plants varied significantly depending on the place of collection, but did not exceed the maximum permissible concentrations. The concentration of zinc in some of the herbal collection points exceeded the maximum permissible concentrations. The need to study the content of heavy metals in plants is due to the fact that they are the primary link in the movement of toxic elements along the trophic chain into the human body. Lead and cadmium accumulate in parenchymal organs, are carcinogenic and affect the morbidity and mortality of the northern population.

Time to the most recent common ancestor (TMRCA) of Sakha men with haplogroup N3a2-M1982 of the Y chromosome was evaluated by 23 STR markers using the mutation rate constant of Y-STR loci that we had previously calculated. The obtained TMRCA values indicate a period of ~1300-1400 years ago (VI-VII centuries AD), associated with the primary expansion of the population. Based on genetic data and analysis of texts from ancient Chinese chronicles, a hypothesis has been put forward about the connection of the ancestral Sakha population with the Yuzhe people, who supplied mammoth ivory to China.

The study is devoted to studying the relationship between the rs9939609 polymorphism of the FTO gene and body mass index (BMI) in the Yakut population. The sample consisted of 521 participants of Yakut nationality without diabetes mellitus. An analysis of the distribution of frequencies of occurrence of alleles and genotypes was carried out, as well as an analysis of BMI indicators in groups with different genotypes of the rs9939609 polymorphism of the FTO gene, during which similarities were found in the ratios of allele frequencies with populations of East and South Asia. The study showed a weak association of obesity with the risk allele A when comparing the group with normal BMI and the combined group of obesity + pre-obesity.

The evaluation of the status of lipid peroxidation and the glutathione system in patients with lung cancer depending on the histological form and stage of the disease has been carried out. The intensity of free radical oxidation of lipids was assessed by the accumulation of malondialdehyde. The indicators of the glutathione system were assessed by the concentration of the reduced form of glutathione and the activity of enzymes: glutathione peroxidase, glutathione reductase, glutathione transferase. Our data indicate that as the clinical stage of lung cancer develops, the level of lipid peroxidation increases, against the background of inhibition of the glutathione reductase activity). Higher levels of malondialdehyde in patients with adenocarcinoma suggest that tumor development may be more closely related to oxidative stress.

The role of pathogenic variants of the MY015A gene in the etiology of hearing loss has not been sufficiently studied in the world, since the larger size of the gene (66 exons, 71 kb) suggests the search for pathogenic variants using NGS technologies, which are not yet sufficiently used in routine practice. In this regard, it is relevant to study the role of pathogenic variants of the MY015A gene in the etiology of non-syndromic forms of hearing impairments The purpose of this work is to describe the rare pathogenic variant c.7636C>T p.(Gin2546*) in the MY015A gene, found in a homozygous state in two siblings with prelingual profound sensorineural hearing loss from a Buryat family. Previously, this variant was found only in one patient in a compound-heterozygous state with another nonsense variant in the MY015A gene in Brazil and described as pathogenic. Detection of variant c.7636C>T p.(Gln2546*) in a homozygous state in Buryat siblings may indicate either a rare case of endogamous marriage or a wider distribution of this variant in the Lake Baikal region.

This article presents the results of studying the course of tuberculosis infection in children and adolescents who have suffered COVID-19 according to a study of ELISA with the presence of Ig G in the blood. The follow-up included 54 patients aged 2 to 16 years with local forms of tuberculosis who were treated in the inpatient conditions of the children’s department of the E.N. Andreev Scientific and Practical Center of Phthisiology from 2020 to 2022. The patients were divided into two groups: the first group – children who had suffered from COVID-19 according to the results of IgG in the blood – 17 patients; the second group – those who had not had COVID-19 with negative results in IgG blood – 37 patients. A comparative medical and social analysis revealed that children who had had COVID-19 had both social and medical risk factors, as well as a burdened epidemiological history, contact with adult patients with acute progressive and destructive forms of pulmonary tuberculosis. Methods of detecting the tuberculosis process in the first group, 88 % of children were detected by contact, 6 % by treatment, 6 % by immunodiagnostics; in the second group, 51 % by contact, 8 % by treatment and 41 % by immunodiagnostics of the patients. In the study of the tuberculosis process in children of the first group, the infiltration phase was recorded in 80 % patients in the reverse development phase: resorption– 10 % and in the calcification phase – 10 %. In the second group, the infiltration phase was in 50 % of children, the resorption phase was in 14 %, and the calcification phase was in 36 % of patients. It should be noted that the effect of a previously transmitted new coronavirus infection on the course and outcomes of the tuberculosis process was not revealed, no correction of chemotherapy was required, and there was no need to increase the duration of treatment.

Tick-borne encephalitis (TBE) is a natural focal viral infection that occurs with high fever and intoxication. It is characterized by damage to the gray matter of the brain and/or the membranes of the brain and spinal cord, with the development of meningitis, meningoencephalitis or encephalomyelitis. The disease can result in persistent neurological and psychiatric conditions, and even death. The carriers of tick-borne encephalitis are ixodid taiga ticks. This type of tick is especially proactive in the spring and summer, endangering adults and children. Infectioning of a person occurs after a tick bite. The causative agent of tick-borne encephalitis is a neurotropic, RNA-containing virus. Tick-borne encephalitis is characterized by increasing neurological symptoms. The symptoms after an encephalitis tick attack are very varied. There are 5 main forms of tick-borne encephalitis: febrile, meningeal, meningoencephalitic (occurs in 15 % of the country as a whole, and twice as often in the Russian Far East). To diagnose with tick-borne encephalitis, it is necessary to take into account clinical manifestations (damage to the central nervous system), epidemiological data (time of the year, presence of vaccination, fact of a tick bite) and laboratory methods of specific diagnosis. The Republic of Sakha (Yakutia) is not an endemic region for the spread of TBE. However, in recent years due to climate change, the number of ticks and bites in this area has increased. This article describes a case of TBE in a 6-year-old child. The disease was extremely severe and resulted in death. Despite the fact that TBE is an extremely rare pathology in our republic, screening for this pathology must be carried out during the tick season.

This paper presents a system for the formation of natural science literacy in biology lessons usingvarious tasks. The relevance of pedagogical experience isthe formation in schoolchildren of a sense of the need forself-education and independent acquisition of knowledge.But most of the students are not able to independentlyacquire knowledge, therefore, it is necessary to developtasks that will guide the work of students, and thus theywill develop natural science literacy. The development ofnatural science literacy skills together with informationtechnology in biology lessons contributes to the positivedynamics of the quality of students’ knowledge, increasingthe motivation for learning activities.
