The policy of import substitution as the basis for economic security and well-being of society

The study presents the analysis of import substitution opportunities on separate branches of economic activity, preceding the realization of import substitution policy with the aim to support national economic security, which is essential for the contemporary society welfare insurance. Currently, social well-being is considered to be the reflection of economic activity, the instrument of state influence on the society, as well as an indicator of the social security system. Due to the fact that Russia is integrated into the world economy, the foreign-economic policy currently is playing an important role in the development of national security and the state's interest to the spheres of economy considering external and internal threats. Decline in external economic conditions may result in serious consequences for the functioning and development of the country as well as for the trade and investment activities, which will further lead to the decline in export, withdrawal of capital, recession of industrial production, trade and investment sphere, fall of GDP and living standards. Thus, considering the current state of instability in the world economy and the growing political tension in relation to Russian Federation, the measures to increase economic security in the country should be taken. The policy of import substitution is considered to be one of the major solutions nowadays

Using radio astronomical receivers for molecular spectroscopic characterization in astrochemical laboratory simulations: A proof of concept

We present a proof of concept on the coupling of radio astronomical receivers and spectrometers with chemical reactorsand the performances of the resulting setup for spectroscopy and chemical simulations in laboratory astrophysics. Several experiments including cold plasma generation and UV photochemistry were performed in a 40\,cm long gas cell placed in the beam path of the Aries 40\,m radio telescope receivers operating in the 41-49 GHz frequency range interfaced with fast Fourier transform spectrometers providing 2 GHz bandwidth and 38 kHz resolution. The impedance matching of the cell windows has been studied using different materials. The choice of the material and its thickness was critical to obtain a sensitivity identical to that of standard radio astronomical observations. Spectroscopic signals arising from very low partial pressures of CH3OH, CH3CH2OH, HCOOH, OCS,CS, SO2 (<1E-03 mbar) were detected in a few seconds. Fast data acquisition was achieved allowing for kinetic measurements in fragmentation experiments using electron impact or UV irradiation. Time evolution of chemical reactions involving OCS, O2 and CS2 was also observed demonstrating that reactive species, such as CS, can be maintained with high abundance in the gas phase during these experiments.Comment: Accepted for publication in Astronomy and Astrophysics in September 21, 2017. 16 pages, 18 figure

Изучение цитокинов в крови больных туберкулезом, ассоциированным с вич-инфекцией

In the present work the data of comparative studying the cytokine status (serum concentration and spontaneous production IL-4, IFN-g, TNF-a) at HIV-infected and HIV-non infected persons with the active for the first time revealed tuberculosis, and also an establishment of possible interrelation between these parameters and amount of virus loading, level CD4+T-cell in blood of HIV- infecte patients from TB (group HIV/TB). In process of progressing associated HIV/ТВ infections and development of heavier forms of TB the increase serum content IFN-g and TNF-a testifying about displacement of balance aside increases proinflammatory cytokines on a background of decrease in number CD4+T-cell, increase of virus loading of a HIV is marked. The received results testify about immunosupreses with an exhaustion of functional reserves mononuclear cells of the peripheral blood aggravated in process of progressing of disease, being one of pathogenetic mechanisms of formation of secondary diseases, both virus, and the bacterial nature.В настоящей работе представлены данные сравнительного изучения цитокинового статуса (сывороточной концентрации и спонтанной продукции IL-4, IFN-g, TNF-a) у ВИЧ-инфицированных и ВИЧ-еинфицированных лиц с активным впервые выявленным туберкулезом, а также установление возможной зависимости между этими показателями и количеством вирусной нагрузки, уровнем CD4+T-лимфоцитов в крови ВИЧ-инфицированных больных с активным впервые выявленным туберкулезом (группа ВИЧ/ТВ). По мере прогрессирования ассоциированной ВИЧ/ТВ инфекции и развития более тяжелых форм туберкулеза отмечается увеличение сывороточного содержания IFN-g и TNF-a, свидетельствующее о смещении баланса в сторону увеличения провоспалительных цитокинов на фоне снижения числа CD4+T-лимфоцитов, нарастания вирусной нагрузки ВИЧ. Полученные результаты свидетельствуют об иммуносупрессии с истощением функциональных резервов мононуклеонарных клеток периферической крови, усугубляющейся по мере прогрессирования заболевания, являющейся одним из патогенетических механизмов формирования вторичных заболеваний как вирусной, так и бактериальной природы

Requirements for DNA bubble structure for efficient cleavage by helix-two-turn-helix DNA glycosylases

Oxidative DNA lesions, constantly generated by both endogenous and environmentally induced reactive oxygen species, are removed via the base excision repair pathway. In bacteria, Fpg and Nei DNA glycosylases, belonging to the helix-two-turn-helix (H2TH) structural superfamily, remove oxidised purines and pyrimidines, respectively. Interestingly, the human H2TH family glycosylases, NEIL1, NEIL2 and NEIL3, have been reported to prefer oxidative lesions in DNA bubbles or single-stranded DNA. It had been hypothesised that NEIL2 might be involved in the repair of lesions in transcription bubbles; however, bubble-like structures may appear in other cellular contexts such as displacement loops (D-loops) associated with transcription, recombination or telomere maintenance. The activities of bacterial Fpg and Nei on bubble substrates were not addressed. Also, it is not known whether H2TH enzymes process bubbles containing the third DNA or RNA strand, and how the bubble length and position of the lesion within a bubble affect the excision. We have investigated the removal of 8-oxoguanine (8-oxoG) and 5,6-dihydrouracil (DHU) by Escherichia coli Fpg and Nei and human NEIL1 and NEIL2 from single-strand oligonucleotides, perfect duplexes, bubbles with different numbers of unpaired bases (6-30), bubbles containing the lesion in different positions and D-loops with the third strand made of DNA or RNA. Fpg, NEIL1 and NEIL2 efficiently excised lesions located within bubbles, with NEIL1 and NEIL2 being specific for DHU, and Fpg removing both 8-oxoG and DHU. Nei, in contrast, was significantly active only on DHU located in double-stranded DNA. Fpg and NEIL1 also tolerated the presence of the third strand of either DNA or RNA in D-loops if the lesion was in the single-stranded part, and Fpg, Nei and NEIL1 excised lesions from the double-stranded DNA part of D-loops. The presence of an additional unpaired 5 '-tail of DNA or RNA did not affect the activity. No significant position preference for lesions in a 12-mer bubble was found. Overall, the activities of Fpg, NEIL1 and NEIL2 on these non-canonical substrates are consistent with the possibility that these enzymes may participate in the repair in structures arising during transcription or homologous recombination
