The pressure effect up to 30 GPa on the structural and electronic properties of crystalline anthracene and tetracene were studied within the framework of density functional theory with van der Waals interactions. Lattice parameters, bulk modulus and cohesive energy were calculated. The pressure dependence of interplanar angles, which describe the relative packing of molecules in the crystal, has been calculated. The calculated electronic band structures demonstrate the dependence of energy gap under pressure. Energy gap in crystalline anthracene monotonously decreases with increasing pressure. The tetracene energy gap decrease from 2.39 to ∼0 eV at 26 GPa. Further increase of pressure subsequently increases energy gap. © 2017 Elsevier B.V.

Fourier transform infrared (FTIR) spectroscopy allows identifying fruit raw material. The obtained individual infrared (IR) spectra and spectral characteristics (the intensity of absorption bands and the area under the spectral absorption curve) are strictly specific for each type of raw material and are determined by its structure and chemical composition. The investigation of the FTIR application for the identification of fruit raw material in complex food systems showed that this technique can determine the presence of raw fruit in the product, but does not identify its type. During a series of sequential experiments, IR spectra of anhydrous fruit raw material were obtained (strawberry, raspberry, cinnamon rose, gooseberry, cherry, banana, and kiwi). The spectra result from oscillatory motion of molecules, namely from transitions between vibrational levels of the main electronic state of molecules. The analysis of the spectra shows that their pattern is strictly specific for each type of raw material. However, all types of raw material have areas of absorption bands that are similar in location, but different in intensity. © 2017, Pharmainfo Publications. All rights reserved.

The carbohydrate composition of relevant fruits and berries has been determined in this study. The titrated acidity has been stated, which amounts to 0.3-1.6%. The qualitative composition of organic acids in relevant fruits and berries has also been determined. The content of vitamins has been identified. It is shown that below mentioned fruits and berries include such vitamins as thiamine, riboflavin, folacin, carotene and vitamin C. It is proved that the total amount of minerals or ash in the composition makes 0.2-0.54%. It has been established that macro-, micro- and ultramicroelements are found in ash composition. It has been designated that the content of toxic elements in the berries does not exceed the permissible level. It is proved that the qualitative composition and the quantitative content of individual elements are different, which is due to their biological characteristics, species specificity, accumulated elements, and availability of soils with accessible forms of elements. It has been determined that the organoleptic method cannot be applied to identify the species when evaluating and identifying processed fruits and berries. © 2017, Pharmainfo Publications.

We prove that the set of compact elements in the group extension of the 3D Heisenberg group by SO(2) (so-called oscillator group) is not dense. We also give a new proof of the following criterion: The set of compact elements of a connected Lie group G is dense in G if and only if every Cartan subgroup of G is compact.

The set Hom(G;H) of all homomorphisms from a group G to a group H is a group with respect to the operation of pointwise products iff the images of any two such ho- momorphisms commute element-wise; in this case, the group is commutative. For finite G and H, we study algebraic properties of this group and of the union Hom (G;H) of the images of all homomorphisms from G to H. Let exp(G) be the minimal positive integer n such that xn = 1 for all x ∈ G, let G′ be the commutator subgroup of G, q = exp(G=G′), and let Ωq(H) be the subgroup of H generated by all elements of order q. We obtain the following results. If Hom(G;H) is a group, then Ωq(H) is commutative and the groups Hom(G;H) and Hom(G=G0;q(H)) are isomorphic. Conversely, if Ωq(H) is commutative and Φ(G′) = (1) for all Φ ∈ Hom(G;H), then Hom(G;H) is a group. If Hom (G;H) is a subgroup of H, then it is endomorphically admissible in H. If G is a finite p-group such that exp(G) = exp(G=G0) = q and H is a regular p-group, then Hom (G;H) = Ωq(H).

For the purpose of identifying and confirming authenticity of wild fruits, berries, nuts, assessing conformity with the requirements or specific information about them, identification is used. For the fruit raw materials, species identification, i.e. identification of the type of products in the assortment, is important. During an expertise of quality of the fruit raw materials, confirmation of quality and safety conformity with the regulatory requirements is the primary goal. However, the existing base of normative documents is not sufficient for full expertise of quality of fruit raw materials, due to the lack of documentation about certain types of raw materials; the existing instruments do not contain a complete list of requirements to quality and safety, regulatory documents are neither updated nor harmonized, given the current economic state. The article shows the results of assessing the quality of the studied fruit raw materials, for example: Rubusidaeus (raspberry, variety Nagrada), Ríbesúva-críspa (common gooseberry, Cooperator variety), Fragaria (remontant strawberry, the Early Berdsk variety), Rosa majalis Herrm (cinnamon rose), Prunusfruticose (steppe cherry, variety Altai swallow), Músaparadisiaca (banana, variety “extra”), Actinidiadeliciosa (gourmet kiwi) for organoleptic, physico-chemical parameters, according to the existing State Standards. It has been revieled that the content of toxic elements (cadmium, mercury, arsenic, lead) does not exceed the allowable level. It has been established that indicators of quality of the studied types of the fruit raw materials meet the regulatory requirements and may be used for further tests aimed at developing the method of identifying the type of fruit raw material in food products. © 2017, Pharmainfo Publications.

The technology of preparing curd mousse has been developed. The prepared curd mousse has smooth, creamed texture, the taste and essence are purely sour and milky with a pronounced flavor of added fruit-and-berry builders, as well as with the added builder taste. The whole mass color is smooth and has the color of the added builder. The trading researches related to indicators of the quality of the prepared curd mousses with kiwi and cherry were made according to organoleptic, physical and chemical and micro-biological indicators. The analysis of organoleptic indicators of samples of curd mousses with kiwi showed that sample 8 had a smooth, soft texture, sufficiently solid, without tangible elements of kiwi. It entirely complied with the requirements of regulatory documents (5 points). It had pure pleasant slightly sour taste (5 points). The favor of kiwi slightly smelled (5 points). The general impression about the mousse was 20 points. Mousse sample 7 with the 30% kiwi builder had close quality indicators and it was also estimated as excellent. As curd mousses used various concentrations of fruit-and-berry builders, the degree of their impact on the active acidity of various test samples was studied. The pH indicator has an impact on the colloid state of proteins of the dairy product, the growth of useful and harmful micro-flora, and activity of ferments. © 2017, PharmaInfo Publications.

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.

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.
