    The review analyzes literature data and the results of our own research on the role of reactive nitrogen species (NO, NO2, N2O3) in the initiation and progression of tumors. The possibility of modulating the activity of inducible NO synthase by the biologically active components of plant products and their effect on carcinogenesis is analyzed. Possible mechanisms of the ambiguous action of NO and its metabolic products in the mechanisms of carcinogenesis are discussed. The generalization and analysis of these data allowed us to formulate some principles for the use of substances that modulate the activity of inducible NO synthase and affect the formation of NO and its metabolic products in inhibiting carcinogenesis.Π’ ΠΎΠ±Π·ΠΎΡ€Π΅ Π°Π½Π°Π»ΠΈΠ·ΠΈΡ€ΡƒΡŽΡ‚ΡΡ Π΄Π°Π½Π½Ρ‹Π΅ Π»ΠΈΡ‚Π΅Ρ€Π°Ρ‚ΡƒΡ€Ρ‹ ΠΈ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ собствСнных исслСдований ΠΎ Ρ€ΠΎΠ»ΠΈ Π°ΠΊΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ„ΠΎΡ€ΠΌ Π°Π·ΠΎΡ‚Π° (NO, NO2, N2O3) Π² ΠΈΠ½ΠΈΡ†ΠΈΠ°Ρ†ΠΈΠΈ ΠΈ прогрСссии ΠΎΠΏΡƒΡ…ΠΎΠ»Π΅ΠΉ.

    The paper analyses the models of cultural and civilizational identification among the residents of Russian and Ukrainian border regions formed under the crisis in Russia-Ukraine relations. The cultural and civilizational identity is understood here as an open or latent identification of an individual or a group of individuals with a socio-cultural matrix, or the historically developed complex of cultural patterns (frames) which entails typification of the value systems, social practices and individual life trajectorie

    The article is devoted to the theoretical analysis of social enterprise development in the reproduction process. As a method, the social sphere has analyzed the system of enterprise effective functioning. As a result, one of the key tasks of the regional reproduction process improvement is the effective development of the social sphere. In conclusion, a necessary condition for the rational combination of sectoral and regional aspects of social infrastructure development planning is the division of the country territory into region

    The article presents an optimized method for the determination of the ratio of 8-oxo-2'-deoxyguanosine (formed in DNA due to the action of active forms of oxygen) to 2'-deoxyguanosine. The ratio was determined by reverse phase HPLC combined with amperometric detection. It was shown that the ratio increases upon oxidative stress caused by the action of large doses of ascorbic acid in samples of DNA isolated from the liver of experimental rats.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½Π° оптимизация ΠΌΠ΅Ρ‚ΠΎΠ΄Π° опрСдСлСния ΠΎΡ‚Π½ΠΎΡˆΠ΅Π½ΠΈΡ 8-оксо-2'-дСзоксигуанозина, ΠΎΠ±Ρ€Π°Π·ΡƒΡŽΡ‰Π΅Π³ΠΎΡΡ Π² Π”ΠΠš Π² Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π΅ дСйствия Π°ΠΊΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ„ΠΎΡ€ΠΌ кислорода, ΠΊ 2'-дСзоксигуанозину ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠΌ ΠΎΠ±Ρ€Π°Ρ‰Π΅Π½Π½ΠΎ-Ρ„Π°Π·ΠΎΠ²ΠΎΠΉ Π’Π­Π–Π₯ Π² сочСтании с ампСромСтричСской Π΄Π΅Ρ‚Π΅ΠΊΡ†ΠΈΠ΅ΠΉ.

    The protective effect of cortexin was investigated with the use of acoustic stress hemorrhagic stroke model. A significant decrease of 8-oxo-2'-deoxyguanosine to 2'-deoxyguanosine ratio in the DNA molecule was shown using brain slices of cortexin treated Krushinsky-Molodkina rats.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΎ влияниС Π·Π°Ρ‰ΠΈΡ‚Π½ΠΎΠ³ΠΎ дСйствия ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚Π° кортСксин Π½Π° ΠΌΠΎΠ·Π³ крыс Π»ΠΈΠ½ΠΈΠΈ ΠšΡ€ΡƒΡˆΠΈΠ½ΡΠΊΠΎΠ³ΠΎ-Молодкиной Π² условиях ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ гСморрагичСского ΠΈΠ½ΡΡƒΠ»ΡŒΡ‚Π°, Π²Ρ‹Π·Π²Π°Π½-Π½ΠΎΠ³ΠΎ акустичСским стрСссом.
