The influence of the processes of digitalization of the economy on the activities of non-financial institutions
The driver of the modern global economy is digital technologies under the influence of which not only new kinds of professions, goods and services are formed, but also challenges for enterprises and the organization of various fields of activity. Digitalization affected the IT-sphere, the activities of financial organizations, production, marketing, healthcare. In the Russian Federation the development of digital technologies in various fields of activity is of great importance, which is reflected in official documents, targeted government programs, business analysts and business practices. All this actualizes the study of the problem of management transformation in non-financial organizations under the influence of the spread of digital technologies.The article examines the strategic challenges facing non-financial organizations of Russia in the digital economy. In the course of solving the tasks set, the formation and development of the digital economy, its essence and content, as well as the prospects for its development in our country, were studied; the program documents and directions of the state program for the development of the digital economy are analyzed. It is proved that involvement in the digitalization processes of not only financial but also non-financial organizations carries a huge potential in terms of improving the value environment of Russian business, since it makes transactions in the shadow economy, corruption schemes, etc. transparent. The authors have proved that the revival of traditional values of Russian entrepreneurship on a new modern basis will increase the level of trust in society, will promote the development of innovations in industry, energy, agro-industrial complex, education and sustainable development of the economy as a whole. The authors structured the challenges of the digital economy for non-financial organizations in our country and formulated proposals for improving the ecosystem of the digital economy

A pair of gametologous genes provides further insights into avian comparative cytogenomics
Exploration of avian gametologous genes, i.e., homologous genes located on both the Z and W chromosomes, provides a crucial information about the underlying mechanism pertaining to the evolution of these chromosomes. The domestic chicken (Gallus gallus (Linnaeus 1758); GGA) traditionally serves as the primary reference subject of these comparative cytogenomic studies. Using bioinformatic, molecular (overgo BAC library scanning), and cytogenetic (BAC-based FISH) techniques, we have investigated in detail a pair of UBE2R2/UBE2R2L gametologs. By screening a gridded genomic jungle fowl BAC library, CHORI-261, with a short labeled UBE2R2L gene fragment called overgo probe, we detected seven specific clones. For three of them, CH261-019I23, CH261-105E16, and CH261-114G22, we identified their precise cytogenetic location on the Gallus gallus W chromosome (GGAW). They also co-localized with the UBAP2L2 gene on the, as was shown previously, along with the CH261-053P09 BAC clone also containing the GGAW-specific UBE2R2L DNA sequence. The fine mapping of the UBE2R2/UBE2R2L homologs in the chicken genome also shed the light on comparative cytogenetic aspects in birds. Our findings provided further evidence that bird genomes moderately changed only during evolution and are suitable for successful use of interspecies hybridization using both overgo-based BAC library screen and BAC-based FISH
PLAGUE INFECTION SIMULATING IN CASE OF INOCULATION WITH AVIRULENT YERSINIA PESTIS STRAINS
Biological method of investigation is specified for the laboratory diagnostics of plague. Mastering of this method by the trainees within the frames of further vocational education is associated with the use of avirulent Yersinia pestis strains and vaccine Y. pestis strain EV line, which while providing safety does not allow for typical pathomorphological pattern on biomodels, as well as for isolation of microorganisms from internal organs. Objective of the study is to select avirulent Yersinia pestis strains and to conduct comparative analysis of the simulation techniques for plague on biomodels. Materials and methods. Utilized were Y. pestis strains. Virulence was evaluated both, in vitro (polymerase chain reaction) and in vivo (LD50 for white mice). Results and conclusions. Set forward have been avirulent Y. pestis strains, prospective in terms of mastering biological method of laboratory diagnostics of plague, and means of their application for simulating plague in biomodels. The designed approach allows for exercising biological methods of plague investigation to the fullest extent, enhancing biological safety of practical studies and reducing the time line for isolation and accumulation of pure bacterial culture
Intraspecific Differentiation of <i>Francisella tularensis</i> Strains Using Multilocus Real-Time Polymerase Chain Reaction
The aim of the study was to develop a method for intraspecific differentiation of the tularemia microbe: subspecies tularensis (subpopulations AI and AII), holarctica (biovars japonica, EryS/R), mediasiatica, and novicida using multilocus real-time PCR. Materials and methods. We used 48 strains of F. tularensis of various subspecies, biovars, and subpopulations. Intraspecific appurtenance of the strains was carried out on the basis of the analysis of the RD-1 region variability applying PCR, the sdhA gene by Sanger fragment sequencing and by the disk diffusion method using disks with erythromycin. The selection of primers and probes was performed using the software available at www.genscript.com and GeneRunner 6.5.52. Sequence homology was assessed using the BLAST algorithm and the GenBank NCBI database. Results and discussion. New data on the structure and occurrence of the differentiation regions RD-8, RD-12, RD-28 of FTT1122c gene and its homologous sequences in strains of tularemia microbe of various subspecies have been obtained. Novel RDhm 346 bp in size, characteristic of strains of the subsp. mediasiatica, holarctica, which is deleted in subsp. tularensis and absent in subsp. novicida has been detected. Based on the detection of the FTT1670, FTT1122с, FTT1067, FTW_2084 loci, a multilocus real-time PCR has been developed – “F. tularensis 4c”, providing for identification of all subspecies of the tularemia microbe, separately for the biovar japonica of the Holarctic subspecies and subpopulations AI, AII of the subspecies tularensis. The PCR specificity was confirmed in the study of strains of tularemia microbe from the fund of the “State Collection of Pathogenic Bacteria” at the premises of the Russian Reserarch Anti-Plague Institute “Microbe”. The results obtained expand the concept of intraspecific genetic heterogeneity of tularemia microbe and possibilities of identifying the causative agent of tularemia using molecular-genetic methods. They are important for understanding the processes of adaptation of the pathogen to circulation in the host organism and environmental objects, the course of evolution and formation of new species of Francisella
