Synthesis and cation-receptor properties of macrocyclic imines of anthraquinone
At the present study a series of crown-containing imines of 1-hydroxy-9,10-anthraquinone with donor and acceptor substituents at the anthraquinone nucleus were synthesized. Compounds were prepared photochemically from the corresponding photoactive 1-phenoxyanthraquinones and 4-aminobenzo-15-crown-5 ether. It was established spectrophotometrically that for crown-containing anthraquinone imines that are characterized by "imine-enamine" prototropic tautomerism, the insertion of acceptor substituents shifts the equilibrium to the "enamine" form. This shift leads to essential spectral changes in complexing chlor- and nitrocontaining macrocyclic imines of anthraquinone with alkali and alkaline-earth metal cations
GluK2-mediated excitability within the superficial layers of the entorhinal cortex
11 pages, 6 pages.-- PMID: 19440371 [PubMed].-- PMCID: PMC2679203.-- Supporting information available:ο»Ώ Figure S1, doi:10.1371/journal.pone.0005576.s001 (0.63 MB TIF).Recent analysis of genetically modified mice deficient in different kainate receptor (KAR) subunits have strongly pointed to a role of the GluK2 subunit, mediating the vulnerability of the brain towards seizures. Research concerning this issue has focused mainly on the hippocampus. However, several studies point to a potential role of other parts of the hippocampal formation, in particular the entorhinal cortex, in the development of epileptic seizures. There is extensive cell death after such seizures in layer III of the medial entorhinal cortex (LIII mEC), making this region of special interest for investigation into related pathological conditions. We therefore characterized KAR mediated currents in LIII mEC pyramidal neurons by several different approaches. Using patch-clamp technique, in combination with glutamate uncaging in horizontal brain slices, we show that LIII mEC neurons exhibit KAR currents. Use of genetically modified mice reveal that these currents are mediated by GluK2 containing KARs. The IV curve indicates the predominant presence of a Ca2+ impermeable and edited form of the KAR. Finally, we show that GluK2 containing kainate receptors are essential for kainate-induced gamma oscillations within the entorhinal cortex.ο»ΏThis study has been funded by the SFB 665 grant and P.B. is a member of and funded by the GRK 1123.Peer reviewe

Improvement of the approaches to improve the health of the population in the regions of Russia
Significant differentiation of socio-economic indicators of the subjects of the Russian Federation indicates significant regional differences in the initial conditions of demographic development. The aim of the study is to develop measures to improve the policy in the field of public health at the regional level in Russia, taking into account the factors of formation of public health. We conducted a factor analysis of the socio-economic situation in the regions, followed by clustering on the basis of a list of selected statistical indicators, which allowed us to develop common approaches to improving health policy for each group of subjects of the Russian Federation, taking into account their main historical, geographical and socioeconomic characteristics

The aim of the work was: to study the Russian auto insurance market using the example of the company "Comestra Insurance". The main tasks were: to study the nature and structure of the insurance market, to characterize the participants of the insurance market, to analyze the state of the Russian insurance market in terms of its dynamics, scale, level of insurance services provided. This topic is relevant, as many different companies open up and try to compete with already established companies. In this work, a number of solutions are proposed that can increase the level of competitiveness of the company as a whole
