Theoretical approaches to analyzing the complexity of macromolecule sequences (DNA, RNA, and proteins) were established prior to the availability of complete genomic sequences. These approaches have experienced a resurgence due to the proliferation of mass parallel sequencing technologies and the exponential growth of accessible data. This article explores contemporary computer methods and existing programs designed to assess DNA text complexity as well as construct profiles of properties for analysing the genomic structures of microorganisms. The article offers a comprehensive overview of available online programs designed for detecting and visualising repeats within genetic text. Furthermore, the paper introduces a novel computer-based implementation of a method to evaluate the linguistic complexity of text and its compression using Lempel-Ziv. This approach aims to identify structural features and anomalies within the genomes of microorganisms. The article also provides examples of profiles generated through the analysis of text complexity. Application of these complexity estimates in the analysis of genome sequences, such as those of the SARS-CoV-2 coronavirus and the Mumps Orthorubulavirus, is discussed. Specific areas of low complexity within the genetic text have been successfully identified in this research.","PeriodicalId":169374,"journal":{"name":"Russian Journal of Biological Physics and Chemisrty","volume":"80 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141376615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal functional for calculating the vibronic absorption spectra of different oxazine dyes in an aqueous solution was discussed based on the author’s present and previous studies. The absorption spectrum shoulder is caused by the vibronic transition. The vibrations involved in vibronic transitions correspond to large-scale molecular movements, are low-frequency, and very weak compared to the others. However, excitation significantly influences the vibrations including the most intensive ones. Photoinduced charge redistribution is local and there is no charge transfer over the dye molecule as a whole. Aliphatic hydrogen atoms prevent water molecules from accessing the N24 nitrogen atom. Considering H-bonded \"solute-solvent\" interactions by three water molecules led to a redshift of the entire spectrum by ≈15 nm. \u0000A strengthening of H-bonds with water molecules upon OX750 excitation was found, which explains this bathochromic effect. The intensity of low-frequency vibrations (including those involved in vibronic transitions) increases with the addition of bound water molecules, especially in an excited state. The vibration of the N-H bond of the imino group is strengthened (especially in an excited state) due to water molecule binding. Noticeable polarization of one water molecule bounded was revealed upon dye excitation. The vibronic model was also applied to calculate the emission spectrum of OX750 in the aqueous media.","PeriodicalId":169374,"journal":{"name":"Russian Journal of Biological Physics and Chemisrty","volume":"12 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141380243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acclimation to different salinity led to a multidirectional change in the cellular composition of the hemolymph of mussels, the most pronounced effect was observed at low salinity. At the same time, both in conditions of low and high salinity, an increase in the intracellular concentration of ROS in hemocytes was noted, which may indicate the development of oxidative stress. In addition, with all changes in salinity, a shift in the osmotic fragility curve was recorded. The results of this work showed that the Mediterranean mussel has a pronounced tolerance to short-term (48 h) fluctuations in salinity, while the decrease in salinity was accompanied by more pronounced functional changes. In turn, the shift in the osmotic resistance curve indicates the involvement of cellular mechanisms of osmoregulation in Mediterranean mussels in adapting to short-term changes in salinity.","PeriodicalId":169374,"journal":{"name":"Russian Journal of Biological Physics and Chemisrty","volume":"150 6‐8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In present work, a mathematical model is proposed that combines two basic concepts of the theory of tumor growth - stochastic growth and the presence of a subpopulation of tumor stem cells. The model is a system of ordinary differential equations that describes the dynamics of subpopulations of tumor cells, taking into account different types of division and transitions between them. An important feature of the system is the maintenance of the equilibrium proportion of tumor stem cells in an unirradiated tumor using feedback. The model was used to interpret experimental data on inhibition of tumor growth after protons irradiation at a dose of 10 Gy only and the combined treatment of irradiation and the inhibitor of DNA synthesis AraC in laboratory mice with grafted melanoma B16. The effect of irradiation only and irradiation in combination with AraC is included in the system using a parameter describing the probability of loss of the cell's ability to successfully divide. As a result, the dependence of tumor volume on time calculated for cases without irradiation, after irradiation and after irradiation with AraC serves as a good approximation of experimental data, which makes it possible to evaluate the parameters of the system.","PeriodicalId":169374,"journal":{"name":"Russian Journal of Biological Physics and Chemisrty","volume":"3 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141378739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, the following tasks were solved in this work: 1) study of the leukocytes reactions in the blood after a single exposure to 60Co γ-radiation on the blood in vitro; 2) mathematical modeling of the fast immune responses using energy indicators of cells. By use of the luminescent microscope, lymphocytes and neutrophils were recognized and examined in donor venous blood smears, vitally stained with a cationic probe 4-(n-dimethylaminostyril)-1-methylpyridinium (DSM). Cell energy activity (EA) in each population was characterized by the sum of transmembrane potentials (TMP) on the outer and mitochondrial membranes, which was assessed by DSM fluorescence intensity and color in cell mitochondria and nuclei. Dose-dependent γ-irradiation effects were evaluated on the basis of digital fluorescent images computer analysis. It was found in the experiments that the change in the TMP of after blood γ - irradiation in doses of 1Gy-5Gy depends on their initial EA. An S-shaped dose dependence was revealed for the irradiated lymphocytes energy activity. The greatest effect of cells energy decrease occurs after irradiation with 4 Gy dose. A model of T-dependent immune responses is proposed in the form a system of nonlinear differential equations before and after blood irradiation, where the concentrations for five cell populations are replaced by their fluorescent variables, which reflect the number of active mitochondria in each population. Such a model is also adequate for describing the rapid phase of the immune response after single-hit radiation exposure of the body.","PeriodicalId":169374,"journal":{"name":"Russian Journal of Biological Physics and Chemisrty","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141381110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With a wide range of genetic engineering capabilities, these bacterial viruses can be modified to achieve precise control and detection of bacteria and thus serve as a new source of antimicrobial agents. In addition to being used in antimicrobial therapy, phages can also be used as transport systems for drug delivery, as vaccines, or can be used for nanosembly of new materials, since phages themselves, their fragments and components are nanoobjects and functioning nanomachines, the assembly process of which is extremely relevant.

MicroRNAs, abbreviated as short non-coding RNA molecules, hold a pivotal role in metabolic regulation, plant responses to environmental stress, and gene expression. Gaining insights into microRNA functions and investigating their target genes can advance drug development and address biotechnological challenges. However, the study and identification of microRNA targets within the genome present technical obstacles. MicroRNA molecules may not exhibit complete complementarity with their mRNA targets. These molecules either contribute to mRNA degradation or inhibit translation, and this process can transpire without full target complementarity. Consequently, the delineation of targets solely based on the principle of complementarity lacks unequivocal clarity. Moreover, a single microRNA molecule can correspond to multiple target genes simultaneously. The solution entails harnessing substantial datasets, employing machine learning techniques, and leveraging neural networks. In bioinformatics, neural networks serve a variety of functions, encompassing the analysis of biomedical data, diagnostics, prediction, classification, and nucleotide sequence segmentation. The pursuit and anticipation of microRNA targets through machine learning methods are currently undergoing vigorous development. A comparative assessment of contemporary neural networks for this task has been executed. A neural network-driven web service for microRNA prediction has been created. The server aspect of the service was developed using the Python programming language and the Flask library. The Mitar neural network, founded on deep learning, was employed.
