Component composition of mycelial mushrooms lipids. pp. 45-50
Summary: The lipid composition of Fomes fomentarius, Laetiporus sulphureus and Cordyceps militaris was investigated. Among the lipids of the submerged mycelium neutral lipids make up 60.0-73.5%, polar lipids - 26.5-40.0%. Neutral lipids are characterised high unsaturated degree fatty acids (S1 of unsaturated fatty acids is 60.5-74.4%); and domination of C18:2 and C16:0 acids (39.0-48.0% è 16.5-34.5%, respectively). Triacylglycerols prevail in neutral lipids fraction (30.5-50.0%), phosphatidylcholine (14.5-23.0%), phosphatidylethanolamine (17.3-27.1%) and cardiolipin (13.0-16.0%) - in polar lipids fraction.

Substituted 3-acil-2,4(1H, 3H)-piridindiones as inhibitors of urease. pp. 51-59
Summary: A comparative kinetic study of the inhibition of the urea hydrolysis by 10 substituted 3-acil-2,4(1H,3H)-piridindiones (PD I-X) has been carried out at 36°C in aqueous solution (pH 3.85). The inhibition had reversible competitive character; the inhibition constants Ki, variying from 0,282 up to 7,26 mM depending of the structure of PD I-X were determined; a relation of the inhibition efficiency and the substituted PD I-X structure are discussed.

Analysis of optimum parametres heat and mass transfer in a finned tubes bundle heat exchanger at the expense of combustion flue gases deep cooling. pp. 60-68
Summary: The model for calculation of local heat and mass transfer parameters in a tube bundle of condensed heat using apparatus at the expense of deep cooling of the flue gases has been developed. The model allows receiving distribution of parameters condensing vapor-gas flow both on length of a pipe, and on depth of crass-section streamline tube bundle that gives the possibility of a choice and a justification of optimum geometrical characteristics of condensed heat using apparatus under various entrance thermodynamic parameters.

Thermogravimetric analysis of flaxseed (Linum usitatissimum L.) biologically active components. pp. 69-78
Summary: Possibilities and application of differential thermogravimetric analysis (TG) in flax biology studies were analyzed. TG analysis is a very effective and informative method of components study in biology. TG optimal conditions of flaxseed analysis were experimentally established (test of cotyledon-embryo fraction). Comparison of data of Kjeldal and Soxlet with TG results corroborates validity of thermal analysis in estimating flaxseed composition. Significant correlation between EA values and contents of the saturated/unsaturated fatty acids was revealed. Flax cultivar classification based on TG data was revealed as highly effective and corresponding to systematic position of investigated samples.

Peroxidase activity of cultural liquid îf Phellinus robustus K fungus in oxidation of pyrogallol and tetramethylbenzidine in water and water-organic medium. pp. 79-92
Summary: It has been shown that peroxidase of cultural liquid (CL) of the fungus Phellinus robustus K oxidizes pyrogallol and tetramethylbenzidine (TMB) in buffered solution and mixture "water - dimethylformamide (DMF)" with high efficiency as compared with horseradish peroxidase (HRP). CL free from proteins increases an operational stability of HRP, but reduces its thermostability above temperature 50°C. CL protects fungal peroxidase from inactivation by DMF, which inhibits fungal peroxidase in the TMB oxidation by mixed type: with increasing DMF concentration the Michaelis constant is increased but efficiency of oxidation TMB (Vmax/Km) is decreased. DMF inhibits the fungal peroxidase less than HRP. Sodium dodecyl sulfate reduces an operational stability of fungal peroxidase and the oxidition rate of TMB in a mixture "water - DMF", but it favourably effects on these enzyme characteristics in 30 mM universal buffer, pH 8,0. In the presence of fungal peroxidase the ammonium sulfate proceeds the mixed type activation of pyrogallol oxidation in 10 mM citrate-phosphate buffer, pH 4,5, but ammonium chloride and thiocyanate inhibit this process. Activity and operational stability of fungal peroxidase does not vary at multiple freezing and defrost of CL. Extracellular peroxidase of Ph. robustus K is possible to use in the practical purposes as not purified and partially purified samples containing phenolic and polyphenolic compounds of CL.

The estimation of ERBB2 protooncogene relative expression level by real time PCR. pp. 93-101
Summary: In this paper we proposed a method of quantifying the relative level of expression ERBB2 protooncogen. The comparative analysis of suitability of genes POLR2A and GAPDH for use as the internal control of amplification is carried out. It was found that the gene POLR2A can not be used as a reference for assessing the relative level of expression of ERBB2 as between the levels of expression of these genes no statistically significant relationship. The relative level of expression of ERBB2 determined in 155 samples of breast tumors. To create a positive control amplification, as well as the calibration samples used to construct a standard curve of cloned full cDNA ERBB2 gene and GAPDH. The comparative analysis of results of quantitative research of relative level of an expression ERBB2 with the data of immunohistochemical (IGH) study of the same samples is conducted. A comparison of the results of two methods for assessing the status of ERBB2 demonstrated high compliance in respect of cases of breast cancer, the categories 0 and 1 + (89.7% and 75.9% respectively) and confirmed the need for mandatory use of IGH to confirm ERBB2-positivity in patients with protooncogen hyperexpression according to the polymerase chain reaction (PCR) in real time.
