Published: January 2020

The immunogenetic characteristics of cattle blood groups are their high variability and heterogeneity. Population processes that occur under the influence of selection pressure can be estimated on the basis of the analysis of the antigen-frequency characteristics of blood groups. Using specific herds as an example, statistical indicators were calculated, and the choice of a statistical method for identifying micropopulation processes was rationalized. A two-sample Student’s t-test for paired samples on the basis of immunogenetic indicators helped to establish differences between populations and identify processes in blood group systems.

Published: January 2020

The problems of monitoring of morphofunctional changes in the process of human adaptation to the changed climatic and geographic conditions of living and study are considered in the article. Various mechanisms of adaptive rearrangements of the organism are described. Changes in the morphofunctional status occur when foreign students adapt to the conditions of the sharply continental climate of the Volgograd region. Those changes cause multidirectional reactions of the cardiovascular system. A satisfactory adaptation response was found in 58.8% of cases: reduction of body weight deficit, load on the myocardium, and increase in the functional capabilities of the cardiovascular system. In a risk group of students with a deficit of body weight, in 30.0% of cases, the reserve potential of the functioning of the cardiovascular system was spent. This corresponds to maladaptation reactions. It is necessary to take into account the obtained results for organizing the measures of conserve and preserve the health of foreign students coming to Russia for higher education.

Existing osteoplastic materials based on osteoconductive matrices lose their relevance. In this connection, to find the most effective and biocompatible carriers for osteoinductors delivery is an important task. Among the existing growth factors BMP-2 is the most effective and researched. Highly porous polylactide (PLA) granules and granular deproteinized bone material Bio-Oss were studied as carriers. Highly porous PLA granules were more effective than Bio-Oss. When using the minimum effective dose of BMP-2 for rats of 10 μg/ml impregnated in highly porous PLA granules, osteogenesis was induced in the calvarial critical-size defect and 18 ± 8% of the defect was filled with a new bone. There were no inflammatory reactions in the PLA granules implantation area. During subcutaneous implantation in rats it was shown that giant multinuclear cells took part in the resorption of the material. Their number was statistically significantly higher in the PLA granule implantation area than Bio-Oss and amounted to 71 ± 23 versus 30 ± 8 cells per 1 mm2. The obtained data showed that highly porous PLA granules were a promising basis for osteoinductive osteoplastic materials.

Published: January 2020

Chlamydiosis of farm animals is a large group of diseases united etiologically. They differ in the nature of the course of the infectious process and the forms of its clinical manifestations. Often, chlamydiosis of pets shows neurological symptoms.Thus, the study of hemato-encephalic barrier passability by experimental chlamydiosis is of some interest. The final brain hemispheric tissues from rats experimentally infected with the chlamydiosis agent of the Laurie strain were chosen as the subject of the studies. The results of studies have shown that chlamydia disrupt the barrier functions of endothelium. Endothelial cells within blood vessels form a semipermeable barrier between the contents of the vessels and the tissues surrounding them. When examining the vascular channel in the control group of rats, it was clearly observed that endothelial cells fit closely together and interact poorly with cells circulating in the blood. The presence of chlamydia in capillary wall in rats infected with the agent results in endothelial cell hypertrophy. As a result, some of the endotheliocytes flow into the lumen of the vessels and break down and contribute to the generalization of infection. As a consequence of this process, changes in dyscirculatory character were observed primarily in gray and white matter and the soft cerebral membrane of the cerebellum with vascular channel damage. Consequently, the pathomorphological changes that occur in the brain substance in experimental chlamydia infection can be regarded as secondary ones that arise in response to circulatory disorders.

Published: January 2020

The use of local raw materials in the mixed fodder formulations for broiler chickens, including non-traditional raw materials, allows to expand the range of manufactured feeds possessing high nutritional properties and biological value. In order to improve the quality and to reduce the production costs of the mixed fodder due to the cheap raw materials use and the reduction of the premix use share, the mixed fodder formulation for broiler chickens was developed. The nutritional and energy value, safety of mixed fodder are determined. It is established that the nutritional and energy value of the mixed fodder with extruded mixture of non-crushed wheat, peat and cones meets the requirements of the current standard for complete feed for poultry and is obtained in accordance with the rules of the production technological process organization and supervision in the mixed fodder industry. The obtained mixed fodder with the use of non-traditional additives is non-toxic. There is no pathogenic microflora. Replacement of the expensive premix with peat, cones and introduction of non-crushed wheat grain into the mixture before extrusion helps to reduce the cost of finished products. In the production of extrudate from non-crushed wheat (98.8 %), peat (0.6 %) and cones (0.6 %), grinding and mixing with other components of the mixed fodder, the proportion of premix P5-1 decreased to 0.52%. The mixed fodder quality improvement is due to the enrichment with vitamins, essential amino acids and vegetable protein by adding cones and peat.

In large cities, soil pollution occurs with heavy metals. Forest stands react to environmental pollution by a decrease in growth and an increase in mortality. A typical object for the city of Moscow is the Timiryazev Academy Forest Experimental District. A comparison of the content of gross forms with the clark content of trace elements in the soil profile revealed a significant excess for the following chemical elements: copper, zinc, lead, arsenic. The content of chromium, nickel, vanadium is lower than the clark content. Comparison of the content of gross forms of trace elements with maximum permissible concentrations showed that the content of nickel, vanadium, cobalt is lower than the maximum permissible concentration. The distribution of the gross forms of the elements along the soil profile is heterogeneous. The maximum content in the profile of sod-podzolic soils falls on the humus horizon, which is associated with the biogenic accumulation of these elements.

Published: January 2020

The aim of the study was to determine and compare the antiradical and antibacterial activity of the Boletus edulis basidiomycetes growing in different climatic zones: the temperate continental Mediterranean (Montenegro) and sharply continental eastern Siberia (Russia). The objects of study were ceps (Boletus edulis) collected in Montenegro (Durmitor National Park, harvested in August 2019) and in Russia (Siberia, Abansky district, harvested in August 2019). Mushrooms dried and crushed to a powder state were used to obtain aqueous extracts (water module 1:100). The antiradical activity of aqueous cept extracts was studied by UV and visible spectroscopy using a stable model radical of 2,2-diphenyl-1-picrylhydrazyl. For antiradical activity studies, samples were taken after 30, 60, 90 min of extraction. Antibacterial activity was evaluated by the difference in the diameter of the colonies of the test bacteria Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus 209p and Acinetobacter baumannii. It was shown that under the same conditions for sample preparation and analysis, Siberian ceps have a high antiradical activity value (the maximum value is 75% for mushrooms from Siberia against the maximum value of 33% for mushrooms from Montenegro, respectively). The results of the evaluation of antibacterial activity showed that regardless of the climatic zone of the growth of mushrooms, their aqueous extracts obtained after 30 minutes of extraction exhibit bacteriostatic effect in relation to all strains of bacteria. Longer extraction (more than 60 min) leads to the stimulating effect of Boletus edulis extracts on the growth of the same bacteria.

Honey bees perform 80-95% of all pollination work. Among many species of pollinating insects, honey bees are the main ones in pollination of plants. Bees live in families consisting of many thousands of individuals. They are adapted to highly specialized food, consuming only two main types of food - nectar and pollen, collecting them from the flowers of plants. Bees not only collect food for themselves, but also process it for long-term storage, protect it from enemies and pests, and regulate its consumption in summer and winter. Families of bees can live and breed in the hollows of trees without human influence. It is necessary to change the strategy and tactics of combating quarantine diseases of bees. The most favorable for medical and recreational activities is the autumn period and the beginning of wintering. During this period, in the natural focus, the mechanisms of transmission of pathogens and their distribution are reduced to a minimum, except for the transmission of pathogens through food (honey, candi). But it is possible to eliminate. Work with bee families in winter is possible, does not adversely affect their livelihoods. Currently, work is underway at the Federal State Budgetary Scientific Institution of the Federal Research Center of the Physics and Power Engineering Institute of the Russian Academy of Sciences on the treatment of quarantine diseases of bees. Considering that the epizootic process does not stop under the conditions of quarantine of bee diseases, we propose to ensure strict isolation of infected bee families during treatment, which significantly increases the effect of veterinary measures in the treatment of quarantine bee diseases using artificial feed with medical preparations in the summer. This article discusses aspects of the epizootic process in quarantine bee diseases. On the example of bee varroosis, a strategy and tactics for combating quarantine bee diseases are proposed.

The evolution of microsturcture and mechanical properties of ZYK530 Magnesium alloy during extrusion and die forging compound forming process were studied and analyzed. The results show that the as-cast ZYK530 alloy mainly consists of a-Mg matrix and I-Mg3Zn6Y and a small amount of W-Mg3Y2Zn3 and Mg2Zn3 phases. During extrusion to die forging forming, the grain size of as-cast ZYK530 Magnesium alloy is refined and uniform under the action of three-dimensional compressive stress and high temperature deformation. The I-Mg3Zn6Y phase of ZYK530 magnesium alloy decrease relatively, while the distribution of W-Mg3Y2Zn3 is more obvious, a small amount of Z-Mg12ZnY and Mg-Zn phases and undetermined phases can be observed in the matrix. Tensile test results show that the tensile strength, yield strength and elongation of extruded preformed specimens are increase by 32.6%, 18% and 18% respectively compared with as-cast specimens. The mechanical properties of final forged specimens are improved by 9%, 38.6% and 23% respectively compared with those of extruded preformed specimens. The fracture mechanism changes form as-cast cleavage fracture to mixed fracture mechanism of toughness and brittleness.
