STATE REGULATION AND ENTERPRISES PERFORMANCE SUPPORT INTO TOURISM AND RECREATION FIELD

The article describes the main documents regulating the state regulation of the tourism industry in the Republic of Kalmykia, analyzes the tourism potential of the region and the dynamics of the development of tourism and recreation services. The development of tourism and recreation in the territory can serve as one of the tools to combat the main socio-economic problems and increase the competitiveness of the regional economy. Revealing the tourist potential, the republic will get the opportunity to develop business in this direction, which is an important factor in the process of attracting new money flows and investments in the economy. It is the development of the tourism industry on the territory of the Republic of Kalmykia that can serve as one of the tools to combat major socio-economic problems, ensure the creation of new jobs and expand the sphere of small and medium-sized businesses, lead to a reduction in the outflow of able-bodied young people, as well as provide prerequisites for improved competitiveness. economy of the region. Key words: state regulation, tourism, region, domestic tourism, competitiveness

Modulation of Hippocampal Astroglial Activity by Synaptamide in Rats with Neuropathic Pain

The present study demonstrates that synaptamide (N-docosahexaenoylethanolamine), an endogenous metabolite of docosahexaenoic acid, when administered subcutaneously (4 mg/kg/day, 14 days), exhibits analgesic activity and promotes cognitive recovery in the rat sciatic nerve chronic constriction injury (CCI) model. We analyzed the dynamics of GFAP-positive astroglia and S100β-positive astroglia activity, the expression of nerve growth factor (NGF), and two subunits of the NMDA receptor (NMDAR1 and NMDAR2A) in the hippocampi of the experimental animals. Hippocampal neurogenesis was evaluated by immunohistochemical detection of DCX. Analysis of N-acylethanolamines in plasma and in the brain was performed using the liquid chromatography-mass spectrometry technique. In vitro and in vivo experiments show that synaptamide (1) reduces cold allodynia, (2) improves working memory and locomotor activity, (3) stabilizes neurogenesis and astroglial activity, (4) enhances the expression of NGF and NMDAR1, (5) increases the concentration of Ca2+ in astrocytes, and (6) increases the production of N-acylethanolamines. The results of the present study demonstrate that synaptamide affects the activity of hippocampal astroglia, resulting in faster recovery after CCI

Interaction of hematopoietic CD34(+) CD45(+) stem cells and cancer cells stimulated by TGF-beta 1 in a model of glioblastoma in vitro

The majority of modern treatment methods for malignant brain tumors are not sufficiently effective, with a median survival time varying between 9 and 14 months. Metastatic and invasive processes are the principal characteristics of malignant tumors. The most important pathogenic mechanism is epithelial-mesenchymal transition (EMT), which causes epithelial cells to become more mobile, and capable of invading the surrounding tissues and migrating to distant organs. Transforming growth factor-beta 1 (TGF-beta 1) serves a key role in EMT-inducing mechanisms. The current study presented the interaction between hematopoietic stem cells and glioblastoma cells stimulated by TGF-beta 1 in vitro. The materials for the study were hematopoietic progenitor cell antigen CD34(+) hematopoietic stem cells (HSCs) and U87 glioblastoma cells. Cell culture methods, automated monitoring of cell-cell interactions, confocal laser microscopy, flow cytometry and electron microscopy were used. It was demonstrated that U87 cells have a complex communication system, including adhesive intercellular contacts, areas of interdigitation with dissolution of the cytoplasm, cell fusion, communication microtubes and microvesicles. TGF-beta 1 affected glioblastoma cells by modifying the cell shape and intensifying their exocrine function. HSCs migrated to glioblastoma cells, interacted with them and exchanged fluorescent tags. Stimulation of cancer cells with TGF-beta 1 weakened the ability of glioblastoma cells to attract HSCs and exchange a fluorescent tag. This process stimulated cancer cell proliferation, which is an indication of the ability of HSCs to 'switch' the proliferation and invasion processes in glioblastoma cells
