    Abstract Autism spectrum disorder (ASD) is a developmental disorder characterized by the early onset of problems with communication, learning, and behavior. The syndromic form of ASD is caused by monogenic mutations. When it is not possible to find genetic or other known mechanisms, the term "idiopathic autism" is used. A significant part of both syndromic and idiopathic autism is associated with translational deregulation dependent on the mechanistic target of rapamycin (mTOR). In this review, we present both bioinformatic and experimental data that link the mTOR signaling pathway to maternal autoantibody related autism and childhood autoimmune neuropsychiatric disorders such as Sydenham's chorea and pediatric autoimmune neuropsychiatric disorder associated with streptococcal infections (PANDAS). The need for ASD subtyping and the prospects of mechanism-based therapy with inhibitors of the mTOR signaling pathway are also discussed.

    Abstract Preeclampsia (PE) is a severe hypertensive pathology and affects 2-8% of pregnancies worldwide. Its etiopathogenesis is poorly understood, and prognostic biomarkers and effective treatments are unavailable for this pregnancy complication, determining the high rates of maternal and perinatal morbidity and mortality. Racial and ethnic differences in PE incidence are of interest to study in terms of evolutionary medicine because such variability can be considered as a side effect of adaptive changes that have occurred in the genetic structure of modern populations since the dispersal of Homo sapiens from Africa. Genetic diversity at 10 regulatory single nucleotide polymorphisms (rSNPs) associated with PE was studied in North Eurasian populations and world populations of the 1000 Genomes Project. The role of natural selection in the formation of this genetic diversity was assessed at the microevolutionary level. High interpopulation diversity was observed with the greatest contribution being made by allele frequencies of NDRG1 rs3802252 (FST = 0.157). Signatures of natural selection were detected for rs10423795 of LHB, rs2167270 of LEP, rs2227262 and rs3802252 of NDRG1, rs56153523 and rs8109071 of SYDE1, and rs72959687 of INHA. The results are consistent with two evolutionary hypotheses of PE, namely, those of ancestral susceptibility and genetic conflicts.

    Abstract The viscoelastic parameters of the cell can report on the cell state, cellular processes and diseases. Cell mechanics strongly rely on the properties of the cytoskeleton, an important system of subcellular filaments, especially on the high-level structures that actin forms together with actin-binding proteins (ABPs). In normal cells, components of the cytoskeleton are highly integrated, and their functions are well orchestrated. In contrast, impaired expression and functioning of ABPs lead to the increasing ability of cancer cells to resist chemotherapy and metastasize. ABP-mediated changes in the cytoskeleton architecture can lead to changes in the mechanical properties of the actin network, both locally and at the level of the whole cell. Until now, in cancer-related studies, mechanical data have been used less frequently, compared to biochemical tests or cell migration assays. Here, we will review current methods for analyzing the mechanical properties of cells and provide the available data on the contribution of ABPs in determining cell mechanical properties important for the investigation of cellular functions, particularly in cancers.

    Abstract We aimed to explore the potential link of maternal age at menarche (mAAM) gene polymorphisms with risk of the fetal growth restriction (FGR). This case (FGR)-control (FGR free) study included 904 women (273 FGR and 631 control) in the third trimester of gestation examined/treated in the Departments of Obstetrics. For single nucleotide polymorphism (SNP) multiplex genotyping, 50 candidate loci of mAAM were chosen. The relationship of mAAM SNPs and FGR was appreciated by regression procedures (logistic/model-based multifactor dimensionality reduction [MB-MDR]) with subsequent in silico assessment of the assumed functionality pithy of FGR-related loci. Three mAAM-appertain loci were FGR-linked to genes such as

    Abstract Early detection and repair of damaged DNA is important for cell functioning and survival. The recently proposed mechanism of intranucleosomal loop formation suggests the relaxation of DNA supercoiling accumulated during transcription through damaged chromatin. The degree of DNA relaxation is affected by the mechanical properties and structure of the double helix. In this work, the consequences from the introduction of a single-stranded break on the mechanical properties of a DNA fragment are studied using molecular dynamics. It is concluded that the introduction of a single-stranded break leads to decreased stiffness and higher elasticity of the damaged DNA molecule as compared to the intact one. This, in turn, may lead to relief in the supercoiling of the defective DNA and to the enzyme arrest.

    Abstract Obesity is one of the major challenges in modern society. More than a third of the world's population suffers froms overweight. This phenotype affects the quality of life and is associated with cardiovascular diseases, diabetes, cancer and reproductive disorders. The population variability of allele frequencies of 26 single nucleotide polymorphisms, in association with obesity and body mass index, according to data from genome-wide association studies (GWASs) is discussed in this study. Genetic variability was analyzed in populations of Northern Eurasia and populations from the human genome diversity project (HGDP). The population samples are characterized by high genetic diversity that correlates with climatic and geographical parameters. The results of the test for searching for natural selection signals revealed a selection effect for rs1167827 of the HIP1 gene, rs7138803 and rs7164727 located in the intergenic region, rs7141420 of the NRXN3 gene, rs7498665 of the SH2B1 gene, and rs7903146 of the TCF7L2 gene.

    Abstract 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. Study design: single center opened retrospective cohort study. The main group is consisted of 72 patients, average age - 71 [56.0; 81.0] years, the part of women - 64.0%. The control group (
    Results: In the following range of mental disorders were identified: a depressive episode (ICD-10 F32) by 31 patients, by 22 - a disorder of adaptive reactions (ICD-10 F43.2), by 5 - delirium not caused by alcohol or other psychoactive substances (ICD-10 F05), by 14 - mild cognitive impairment caused by damage and disfunction of the brain or somatic diseases (ICD-10 F06.7). In comparison with the control group, these patients showed a statistically significant (
    Conclusion: The results of the study confirm the heterogeneity of the structure of mental disorders in the acute form of coronavirus infection, revealing the relations between the clinical picture and laboratory parameters of the immune response to systemic inflammation. Recommendations are given for the choice of psychopharmacotherapy, in conformity with the peculiarities of pharmacokinetics and interaction with somatotropic therapy.

    Abstract Single nucleotide polymorphism (SNP) are the most common type of genetic polymorphisms. Despite the progress in sequencing and postgenomic technologies, point genotyping of SNPs remains the most demanded approach in human and medical genetics. In this paper, the experience in the application of multiple SNP genotyping using MALDI-TOF mass-spectrometry for the analysis of genetic diversity of immune response genes in human populations has been described. It is demonstrated that MALDI-TOF mass-spectrometry is rapid, accurate and efficient method for medium-scale SNP genotyping. In four populations (Russian, Komi, Khant, and Buryat) the similar spectrum of allelic frequencies for 56 SNPs in 41 genes implicated in the regulation of immune response was found. Populations under study have the similar level of genetic diversity and are clustered according their geographic location. Economic effectiveness of MALDI-TOF mass-spectrometry in comparison with a real time PCR technology is estimated.
