30 years' Changes of Probabilistic and Information Characteristics of the Humus Content in Southern Chernozems in Western Siberia The analysis of transformation of the probabilistic-statistical distributions (PSD) of the humus content in southern chernozems at the studied territory in the whole, situated on the Priirtyshsky uval for the 30-year period revealed existence of the tendency to decrease in the humus content in the top layer and its increase in underlying layers of soil. Transformation of PSD of the humus content is followed by very essential reduction of statistical entropy up to 60% of initial value that speaks about essential change of a condition of chernozems in spite of the fact that taxonomically soils don't change. The analysis of information divergence showed that the revealed tendencies in a sandy loam version are expressed more strongly, than in the loamy soils. And the greatest transformation of PSD of the humus content for the studied period happened in a layer 30-50 cm due to increasing of the low boundary of the interval of variation. The revealed transformations of PSD are interpreted from the point of view of interaction of soilforming, climatic and landscape and exogenous processes.

Consequences of eco-toxicological effects of hazardous heavy metals compounds on the benthic communities of river ecosystems The paper presents the results of the analysis of long-term regime hydrochemical information about the hazardous heavy metals (mercury, cadmium and lead) content of the river waters and hydrobiological information about the structural organization of the benthic communities. The possible  changes assessment of the ecological status of river ecosystems was conducted. It is shown, that the variability of the quantitative indicators of the benthic communities is response to the transformation of the component composition of the aquatic environment river’s.  The strengthening processes of environmental regression of  benthic communities takes place in river ecosystems with a high level of contamination of the toxic heavy metals.

The functional state of the organism of calves during cold method of cultivation. Кostesha Nikolay Yakovlevich, Makarevitch Veronika Gennadievna For  the experiment 2 groups of calves were taken. An experimental group of  5 days old calves was put into individual cabins where the temperature was minus 4-5C. The control group was put into similar  cabins where the temperature was 11-12oC. The test of peripheral blood  in the experimental group showed that the quantity of erythrocytes increased significally compared with the control group of calves. The authors believe that moderate stress (according to the increase of cortisol in peripheral blood) stimulates erythropoiesis. Since the 7th  day of the experiment the calves began to gain weight up to 25% compared with the control group.

Evaluation of the rate constants reactions of the alkyl, allyl and aryl radicals with hydrocarbons with use the artificial of neural network Evaluation of the rate constants reactions of the alkyl, allyl and aryl radicals with hydrocarbons with use the artificial of neural network Tumanov Vladimir Evgen’rvich This paper discusses the use of feed-forward artificial neural network to predict the rate constants of organic molecules in the bimolecular radical reactions R + R1H in the liquid phase on the experimental data. The hybrid algorithm of calculation of rate constants of bimolecular radical reactions on the experimental thermochemical data and an empirical index of the reactionary center is offered. This algorithm uses an artificial neural network for a prediction of a classical barrier of bimolecular radical reaction at a temperature of 298 K, a database of experimental characteristics of reaction and Arrhenius's formula for calculation of a rate constant. Results of training and a prediction of the network are discussed. Results of comparison of logarithms of the calculated and experimental of the rate constants are given.

Disorders of cellular and humoral immunity ulcer diseases The article deals with contemporary ideas on the state of immunological reactivity under ulcer disease. The role of immune disturbances in the development of clinical manifestations of ulcer disease is shown. Interrelations of different links of the immune system, correlations between specific immunity and natural protection of the organism are considered. Found that patients observed a variety of disorders immunological reactivity. Violations of the immunological reactivity observed in the acute stage and remain in remission.  

The levels of UV-induced mutagenesis change in case of mutations in chromatin-remodeling proteins encoding genes are combined with the rad54 mutation in yeast Saccharomyces cerevisiae Yeast Saccharomyces cerevisiae DOT1, HSM6 and ASF1 genes encode crucial protein chromatin modifiers. We studied the effects of combining dot1, hsm6 and asf1 mutations with rad54 mutation. It’s demonstrated that the enormous increase of UV-induced mutagenesis is representative for dot1rad54, hsm6rad54 and asf1rad54 double mutants. Simultaneously the levels of survival of these double mutants change under the UV light action.

The effect of Mexidol on clinical and immunological status of patients with chronic obstructive pulmonary disease The assessment of efficiency of meksidol therapy on clinical and immunological status has been made for patients with chronic obstructive pulmonary disease (COPD), the acceptability of physical loads, quality of life and probability of survival of patients with COPD being cousidered against the background of mexidol treatment. It has been established that the use of this preparation in a complex therapy for COPD patients is accompanied by positive dynamics of respiratory symptoms and improves the quality of life of patients. Patients with COPD have a depression of absorbency of neutrophil phagocytics capacity and increasing its metabolic activity with the formation of reactive oxygen species, the probability of a 4 year survival in patients with COPD.  

Research on the influence of endogenous bioregulators, isolated from blood serum and bones of mammals, on the regeneration of amphibian limbs The purpose of this study was to investigate the effect of bioregulators (BR) on anurans limb regeneration and to maintain the viability of the tissues of the developing salamanders regenerate in vitro. During this work it was found that the ability of Xenopus laevis to regenerate hindlimb in metamorphosis stage depends on the level of amputation, while stimulating regeneration by BR isolated from blood serum, decreases when the regenerative capacity increases. BR from serum had a pronounced effect on the regeneration of Xenopus laevis hindlimb in vivo when amputation was in the proximal region. BR from bone and BR from serum had a protective effect on the condition of the tissue regenerated limb of the newt Pleurodeles waltl provided by cultivation in vitro.  

Investigation of thermal resistance and antagonistic properties of the yeast Saccharomyces cerevisiae Using antagonistic properties of some bacteria to inhibit other (pathogenic) has been studied for many years, while little attention was paid to study such properties in yeast. The yeast metabolites and yeast cells action on gram-negative and gram-positive microorganisms was different. Live yeast cells were the most antagonistically active against gram-positive microorganisms and their metabolites - in relation to gram-negative.
