Biochar influence on the development of spring wheat (Triticum aestivum L.) and acidity of soddy-podzolic soil in Western Siberia

The paper purpose was to establish the effect of applying biochar obtained from various organic wastes of agriculture (cow manure, straw), woodworking (pine sawdust) and food industry (pine nut shell), which are typical of Western Siberia, on the morphometric characteristics of plants (using spring wheat (Triticum aestivum L.) as the example) and the soddy-podzolic soil properties. The assessment of biochar influence was performed by a series of vegetation experiments using climatic chambers. As a result, it was found that the introduction of all the noted biochar types into the soil layer leads to a significant (p < 0.05) increase in the morphometric characteristics of spring wheat. For example, when applying the straw biochar to the soil, it results in growing the plant height to the node by 19%, while the number of leaves increased by 8% compared to the control variant. The introduction of biochar from manure leads to the increased length of the spring wheat root by 35%. Moreover, straw and manure biochars contribute to the reduction of soil acidity (increase in pH values from 7.1 to 7.4 and 7.8, respectively). The results of the comprehensive analysis indicate that the agronomic advantages of application of biochars obtained from wheat straw and cattle manure are better compared to biochars from pine sawdust and pine nut shells, which is due to higher concentration of nutrients and substances with alkaline reaction (carbonates and oxides) in the former. The results obtained are useful from the point of view of assessing the environmental risks when applying biochar ameliorants in soils typical of the boreal bioclimatic zone. Subsequent experiments, including studies of the joint application of biochars and fertilizers to the soil, will make it possible to develop recommendations for applying the thermal conversion technology for recycling the regional organic waste into ameliorants that improve soil quality and increase its fertility

FEATURES OF ANTIOXIDANT SYSTEM STATE IN ADOLESCENTS OF EASTERN SIBERIA IN DEPENDS ON THEIR GENDER AND ETHNIC ORIGIN

This research is devoted to studying of features of antioxidant protection system in adolescent boys and girls of various ethnic groups of Eastern Siberia. Study of the peculiarities of processes of antioxidant protection of populations of people of different ethnicity, living in the same geographical conditions, is of undoubted scientific interest. It is especially important to assess metabolic status of a young, growing body to ensure in the future the preservation of reproductive ability. We biochemically evaluated 58 boys of 14-17 years old. Out of them 19 boys were Russian, 29 boys were Buryat population and 10 boys were metises. Also we biochemically evaluated 57 girls. Out of them 21 were Russian, 27 girls were Buryat population and 9 girls were metises. The materials for biochemical studies were blood serum and red cells. The total antioxidant activity of serum and the content of its components (superoxide dismutase, α-tocopherol, retinol, blood-reduced glutathione) were evaluatedbya spectrofluomphotometer «SHIMADZU-1501» (Japan). Statistical analysis was performed by parametric tests. The study was supported by grants of the President ofthe Council of the Russian Federation (Scientific School 494.2012.7). The detected features of antioxidant protection processes in observed adolescents had gender differences, also may be explained by their ethnicity and characterized by different degree of activity of metabolic processes in adolescent boys and girls of different ethnic groups of Eastern Siberia. Study the state of the antioxidant system of the organism can be used as an additional criterion for complex examination of practically healthy adolescents, which significantly enhance the representation about the adaptation possibilities of the organism to external conditions and can be a basis for effective monitoring of reproductive health in the future

The development and mastering of the skills of self-regulation in the course of game biofeedback: psychological analysis

In this paper we present the results of the study of the characteristics of self-regulation skills development using game biofeedback, and psychological predictors of these skills’ mastering in the course of biofeedback training. Analysis of the psychological characteristics associated with/ restraining the learning of self-regulation during training is given. It was shown that the training based on computer biofeedback allows modifying self-regulation profiles of the subjects towards more effective ones. The steadiness of the skills was confirmed

Expression of CXCL4 in microglia in vitro and in vivo and its possible signaling through CXCR3.

Item does not contain fulltextSignaling through chemokine receptor CXCR3 in the brain has been implicated in various brain diseases, as CXCR3 and its ligands are found under these conditions. Recently, a new chemokine ligand for CXCR3 was reported. In humans, an alternatively spliced variant of CXCR3 expressed on microvascular endothelial cells, named CXCR3b, was shown to bind CXCL4. In the periphery, the cellular expression and functions of CXCL4 are well described but in the brain its expression and function are unknown. Here, we show that brain microglia are a cellular source of CXCL4 in vitro and in vivo under neurodegenerating conditions. Microglial migration induced by CXCL4 is absent in CXCR3-deficient microglia, indicating a role of CXCR3. CXCL4 furthermore attenuates lipopolysaccharide-induced microglial phagocytosis and nitric oxide production in microglia and BV-2 cells. Based on these findings, it is proposed that locally released CXCL4 may control microglia responses
