    The article is devoted to studying the processes of spatial development and geo-economic integration of the subjects of the Central Black Earth macroregion in Russia. The authors have developed and tested the methodology for analyzing the spatial potential and assessing the geo-integration of territories. It has been determined that all areas of the Central Black Earth macroregion have high spatial potential. However, a high level of geo-economic integration is characteristic only for the Lipetsk Region. The list of critical breakthrough technologies has been made, and the technological profile of the Central Black Earth macroregion has been formed. A management matrix for selecting priorities and scenarios for the spatial development of the region in the context of smart specialization has been worked out. According to the results of the study, the strategy of international technological specialization in the area of basic technologies of power electrical engineering, nano-, bio-, information and cognitive technologies is promising for the Lipetsk Region. The Belgorod, Voronezh, Kursk and Tambov Regions should choose a strategy of local technological specialization based on the interregional interaction in priority technological sectors

    All around the ITER vacuum vessel, forty-four ports will provide access to the vacuum vessel for remotehandling operations, diagnostic systems, heating, and vacuum systems: 18 upper ports, 17 equatorialports, and 9 lower ports. Among the lower ports, three of them will be used for the remote handlinginstallation of the ITER divertor. Once the divertor is in place, these ports will host various diagnosticsystems mounted in the so-called diagnostic racks. The diagnostic racks must allow the support andcooling of the diagnostics, extraction of the required diagnostic signals, and providing access and main-tainability while minimizing the leakage of radiation toward the back of the port where the humans areallowed to enter. A fully integrated inner rack, carrying the near plasma diagnostic components, will bean stainless steel structure, 4.2 m long, with a maximum weight of 10 t. This structure brings water forcooling and baking at maximum temperature of 240?C and provides connection with gas, vacuum andelectric services. Additional racks (placed away from plasma and not requiring cooling) may be requiredfor the support of some particular diagnostic components. The diagnostics racks and its associated exvessel structures, which are in its conceptual design phase, are being designed to survive the lifetimeof ITER of 20 years. This paper presents the current state of development including interfaces, diagnos-tic integration, operation and maintenance, shielding requirements, remote handling, loads cases anddiscussion of the main challenges coming from the severe environment and engineering requirements

    A web-based genotyping resource for viral sequences

    No full text
    The Genotyping tool at the National Center for Biotechnology Information is a web-based program that identifies the genotype (or subtype) of recombinant or non-recombinant viral nucleotide sequences. It works by using BLAST to compare a query sequence to a set of reference sequences for known genotypes. Predefined reference genotypes exist for three major viral pathogens: human immunodeficiency virus 1 (HIV-1), hepatitis C virus (HCV) and hepatitis B virus (HBV). User-defined reference sequences can be used at the same time. The query sequence is broken into segments for comparison to the reference so that the mosaic organization of recombinant sequences could be revealed. The results are displayed graphically using color-coded genotypes. Therefore, the genotype(s) of any portion of the query can quickly be determined. The Genotyping tool can be found at: http://www.ncbi.nih.gov/projects/genotyping/formpage.cgi

    Screening of anxiolytic properties and analysis of structure-activity relationship of new derivatives of 6-(4-methoxy)-7H-[1,2,4]triazolo[3,4-a][2,3]benzodiazepine under the code RD

    Introduction: Searching for new compounds with anti-anxiety activity resulting from the combination of privileged scaffolds is a promising direction in medicinal chemistry and in the development of new drugs. Anxiolytic potential and cytotoxic properties of previously synthesized molecules, containing fragments of 2,3-benzodiazepine and 1,2,4-triazole – 6-(4-methoxyphenyl)-7H-[1,2,4]triazolo[3,4-A][2,3]benzodiazepines under the generic code RD were studied. Materials and methods: Screening for anxiolytic activity was performed on elevated plus maze (EPM) and open field (OF) test models. Structural and functional analysis of the anti-anxiety activity of the studied substances was carried out. A degree of muscle relaxant effect of the substances was assessed in the tests Grid, Wire, and Rotarod. A cytotoxicity study of RD compounds was carried out using an MTT assay on human hepatocellular carcinoma cells HepG2. Results and discussion: For a number of novel triazolo[3,4-a][2,3]benzodiazepine derivatives, a prominent anxiolytic activity was manifested in terms of EPM test. The results of OF test were consistent with the obtained data and confirmed the presence of the sought activity in the leading compounds. There was no significant effect on muscle tone for the compounds under study. It was observed that RD compounds possessed no cytotoxic properties and were safe for further studies in vivo. Conclusion: Among the new derivatives of 6-(4-methoxyphenyl)-7H-[1,2,4]triazolo[3,4-a][2,3]benzodiazepine under the code RD, substances (RD-4, 12, 13) with a high anxiolytic activity comparable to diazepam and tofisopam were found. The most promising compound is RD-4 due to its pronounced anxiolytic and low cytotoxic properties
