Antioxidant defence enzymes are essential protectors of living organisms against oxidative stress. These enzymes are involved in the detoxification and decomposition of harmful chemical compounds called reactive oxygen species (ROS), which are, first and foremost, a source of intracellular oxidative stress. ROS directly promote the oxidative damage of genes resulting in aberrant regulation of many vital cell processes. As a consequence, the presence of ROS can lead to genomic instability, deregulation of transcription, induction of mitogenic signal transduction pathways and replication errors, all of which may increase the risk of cancer development. Single nucleotide polymorphisms of antioxidant defence genes may significantly modify the functional activity of the encoded proteins; therefore, certain alleles can be established as risk factors for particular cancer types. In the future, these risk alleles may be utilized as genomic markers of cancer predisposition to allow for early prevention measures among carriers of these alleles. The review is devoted to common single nucleotide polymorphisms of the superoxide dismutase (SOD) and glutathione peroxidase (GPX) gene families and their impact on carcinogenesis. The predictive significance of several polymorphisms was determined, and these polymorphisms were recommended for further in-depth research. © 2012 Informa UK, Ltd.

We investigated the electronic structure of crystalline naphthalene and anthracene within the framework of density functional theory including van der Waals interactions (DFT-D). It is established that for better agreement with experimental values it is necessary to use the increased values of the van der Waals radii, which is caused by an overestimated value of the van der Waals interactions in crystalline linear oligoacenes. Utilization of the DFT-D leads to a correct account of the dispersion forces, which results in a high precision of the computed lattice parameters and cohesive energy. Based on the relaxed crystal structures, we have computed the total and deformation electron density and determined the mechanism of chemical bonds formation in crystals of naphthalene and anthracene. It has been established that the chemical bond in molecular crystals is formed under the influence of not only intramolecular but also intermolecular interactions. On the basis of the Mulliken population analysis it was revealed that two C(3) atoms in naphthalene (or C(3) and C(4) in anthracene) have a positive charge and the population of the rest of the carbon atoms increased, as compared with isolated molecule. © the Owner Societies. 2011.

The structural and electronic properties of crystalline 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has been investigated within the framework of density functional theory including van der Waals interactions. The predicted crystal structure compares well with the experimental results at the ambient pressure. The computed lattice parameters and lattice energy have good agreement with experimental data. We study on the structural and electronic properties of the TATB under the hydrostatic pressure of 0-40 GPa. In addition, the electronic structure of the TATB has been studied as a function of uniaxial compression. The isothermal equations of state calculated from the results show good agreement with experiment in the pressure intervals studied. We have also calculated the quasiparticle band structure of TATB with the G0W 0 approximation. © 2014 Published by Elsevier B.V.

Transformations in indium nanolayers have been studied by optical spectroscopy, microscopy, and gravimetry in relation to the thickness of the layers (2-147 nm) and heat treatment temperature (473-873 K) and time (0-120 min). The kinetic curves for the degree of conversion are adequately described by a linear, inverse logarithmic, parabolic, or logarithmic law, depending on the thickness of the indium film and heat treatment temperature. We have measured the contact potential difference across the In and In 2O 3 films and the photovoltage in the In-In 2O 3 system. The results have been used to derive the energy band diagram of the In-In 2O 3 system. A model has been proposed for the thermal transformation of indium films, which involves oxygen adsorption steps, charge carrier redistribution in the In-In 2O 3 interfacial field (positive on the In 2O 3 side), and In 2O 3 formation. © Pleiades Publishing, Ltd., 2012.

Gastric carcinoma is one of the most widespread malignancies worldwide. Interleukins are the key group of cytokines which may have tumor-promoting or tumor-suppressing effect, and receptors for them, of course, have the same importance in this context. However, mechanisms of their impact on tumor are not fully understood up to date. Numerous studies provide conflicting data, that makes picture more confusing and complicated. It is known that single nucleotide polymorphisms in interleukin genes may dramatically affect on protein expression level, or alter its functions, which may lead to gastritis or ulcer, and eventually promote cancer occurrence. Furthermore, some of these genetic polymorphisms may serve as predictive factors for cancer prognosis and prevention. In order to understand the impact of each genetic polymorphism, the review of IL-1B, IL-4, IL-6, IL-8, IL-10, IL17A, IL-17F DNA polymorphisms on gastric carcinoma was done, and risk alleles were recommended for further research. © 2011 American Society for Histocompatibility and Immunogenetics.

The features of pseudosymmetry in crystalline compounds with highly symmetric sublattices are discussed. The symmetry of sublattices higher than the crystal symmetry is manifested in elementary excitation spectra in the form of degenerations and quasidegenerations. The topology of spectral branches is not related to the value of the parameter estimating the degree of pseudosymmetry on the basis of the electron density fraction, which is invariant with respect to operations corresponding to additional symmetry. © 2013 Pleiades Publishing, Ltd.

Three tetragonal, partially occupied oxygen sublattices with a translational symmetry higher than the lattice translational symmetry can be introduced into the cubic perovskite structure. This higher symmetry is determined in the 9D space constructed on three orthogonal 3D subspaces corresponding to the sublattices. The generating matrices, metric tensors, and point symmetry matrices of this multidimensional space are determined. Irreducible stars of the representations of multidimensional space group are projected onto the irreducible stars of the space crystal group. © 2016, Pleiades Publishing, Inc.

In this article we construct all kinds of elementary Prym differentials for arbitrary characters on a variable torus with a finite numbers of punctures and find the dimensions of two important quotient spaces. As a consequence, this yields the dimension of the first holomorphic de Rham cohomology group of Prym differentials for arbitrary characters on torus. Also, we construct explicit bases in these quotient spaces. © Siberian Federal University. All rights reserved.

Transformations in Pb-WO 3 nanodimensional systems are investigated in dependence on the thickness of the Pb and WO 3 films, temperature, and thermal treatment duration by means of optical spectroscopy, microscopy, and gravimetry. The contact potential difference for Pb and WO 3 films and the photoelectric power of Pb-WO 3 systems is measured. A diagram of the energy bands of Pb-WO 3 systems is constructed. A model of thermal transformation for the WO 3 films in Pb-WO 3 systems is suggested. The model involves the redistribution of equilibrium charge carriers on the contact, formation of the ([(V a) ++e]) center during the preparation of a WO 3 film, its transformation into a ([e(V a) ++e]) center during the formation of the Pb-WO 3 systems, and thermal ionization of the ([e(V a) ++e]) center. © 2012 Pleiades Publishing, Ltd.

This article reviews theoretical approaches and the practical experience in governing the formation of urban agglomerations in Russia. Urban agglomerations should be considered to be one of the forms of intermunicipal economic cooperation. Cities of the Kuznetsk Basin are used as an example of cooperative relations between territories with disadvantages of their chaotic formation caused by a lack of coordination between their social and economic policies. Suggestions regarding improving the legislation in the area of intermunicipal collaboration and further studies for choosing an optimal model of government for Southern Kuznets Basin agglomeration are presented. © Pleiades Publishing, Ltd., 2013.
