ABSOLUTE AND RELATIVE WEIGHT DYNAMICS OF THE ROSS 308 BROILER HEARTS WHEN ADDING THE “KOVELOS-SORB” SORBENT TO THE MAIN DIET

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Currently, Ross-308 broilers are actively used in poultry farming. This article presents the main results of the study of the effect of the silicon-containing sorbent “Kovelos-Sorb” on the absolute and relative heart weight of the Ross-308 broiler roosters in the course of 35 days. The heart is one of the most important organs of animals due to its role in the process of blood circulation. It is the heart that promotes the transport of blood with nutrients dissolved in it through the body, which contributes to the regulation of the normal functioning and growth of individual organs and the body as a whole [1], [2]. The sorbent “Kovelos-Sorb” was added in the amount of 0.1% relative to the weight of the main diet.

NON-SPECIFIC DEFENCES AND STRATEGIES FOR OVERCOMING STRESS IN PEOPLE OF PRE-RETIREMENT AGE

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The current article identifies groups of people of pre-retirement age with different coping strategies in a stressful situation based on the type of adaptive reaction and the level of reactivity. In the group of people with signs of chronic stress, the leading coping strategies are observed to be “Confrontation” and “Self-control”. Refusal of vaccination, difficulties in expressing feelings about the reform of the pension system, control of behavior cause tension in the physiological mechanisms of regulating the activity of life-supporting systems and negatively affect the state of physical health. An adequate understanding of the personal role in the occurrence of difficulties (the “Taking responsibility” strategy) contributes to the preservation of the mental and physical health of people classified as a group of satisfactory adaptation. The use of such coping strategies as “Escape-avoidance” and “Positive overestimation” by people with incomplete adaptation processes helps reduce the level of non-specific protection.

THE USE OF LACTOBACILLUS CASEI BASED PROBIOTICS IN BEEKEEPING

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Probiotics are one of the most promising biological drugs for combating bee infections and preserving bee colonies. However, it is necessary to understand that some probiotic (bacillary) strains have an antagonistic effect against pathogenic microorganisms mainly due to the production of antibiotic substances, which can also lead to a restriction of their use and a significant narrowing of the spectrum of probiotics offered for use in beekeeping. The article presents the results of research on the antagonistic spectrum and activity of L. casei strains. The study demonstrates a positive effect and conducts a study of the effect of L. casei on the body of bees.

SCREENING OF ESSENTIAL OILS FOR THEIR ANTIMICROBIAL ACTIVITY

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents the results of a study of the antimicrobial activity of eight commercially available essential oils: orange, lavender, fir, basil, cedar, clove, pine and eucalyptus. The effect of essential oils on Staphylococcus aureus and Tetracoccus sp., which are most often present in the air of classrooms, is studied by the method of sublimation in a sealed container, as well as by the method of diffusion in nutrient agar. The study demonstrates that the most noticeable antibacterial activity against staphylococcus in a 30-minute time interval is shown by essential oils of fir, eucalyptus and clove, while the rest of the tested essential oils show moderate antimicrobial effect. After a 60-minute exposure, a more noticeable inhibition of staphylococcus is observed. However, even in this case, the essential oils of fir, cedar, pine and eucalyptus are observed to be the most effective. The essential oils also show similar antimicrobial activity against tetracoccus, but it is more moderate than against staphylococcus. The method of diffusion in nutrient agar shows a low efficiency of essential oils against staphylococcus and tetracoccus, which may be due to the physicochemical characteristics of the oils. Only the essential oil of eucalyptus and, to a lesser extent, cloves have areas of staphylococcus growth delay.

DETERMINING THE VIABILITY OF PLANTAGO MAJOR (L.) IN SARANSK

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

One of the factors of environmental pollution in the city is the accumulation of heavy metals both in the soil and in the plants growing on it. The article examines the change of some morphometric and reproductive parameters of Plantago major in the context of man-made pollution in the city, taking into account the lead content in the soil and plants of different areas. Increasing anthropogenic impact leads to a reduction of some morphometric characteristics of plants by 1.2-1.8 times. The natural productivity of plantain is in a certain inverse dependence on the degree of anthropogenic pollution. The study determines that the agricultural productivity is less susceptible to change with low man-mad pollution, while with an increased load, it is descreased by 2-3 times.

DETERMINING THE LEVEL OF COGNITIVE RESERVE AS ONE OF THE INDICATORS OF THE POSSIBILITY OF PREVENTING THE NEGATIVE CONSEQUENCES OF COVID-19 IN YOUNG PEOPLE

Posted in 2021, BIOLOGY, Issue №8 (110) August 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article discusses the research on cognitive functions in university students, which indicate a decrease in the cognitive level in the groups of young people under study. According to the results of tests evaluating the functional state of the respiratory and cardiovascular systems in the students, it can be concluded that their vital systems are not all ready to protect their cognitive reserve from the consequences of COVID-19. The identified signs of a decrease in cognitive reserve correspond to indicators of an increase in both personal and situational anxiety. Pathogenetic mechanisms of neurotropic viral lesion contribute to a failure in the autonomic provision of somatic functions in the limbic-hypothalamic-reticular complex. Neurocognitive disorders (according to the global cognitive index and other indicators) are more pronounced in young patients who may also be students with an existing pre-covid cognitive status deficit.

THE INFLUENCE OF TH1/TH2-BALANCE ON THE DEVELOPMENT OF ACUTE GRAFT-VERSUS-HOST DISEASE

Posted in 2013, BIOLOGY, Issue October 2013, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The influence of drugs affecting Th1/Th2-balance on the severity of acute graft-versus-host disease (GvHD) has been evaluated. As laboratory model of acute GvHD the semiallogeneic system C57Bl/6 ®(C57Bl/6 x DBA/2)F1 it was used. In experimental groups mice were injected with poloxamer 407 or 5-azacytidine – drugs with opposite effects on the Th1/Th2-balance. It was established that poloxamer 407 (shifting Th1/Th2-ratio toward Th1) increases mortality of animals and intensity of acute GvHD. Observed effects 5-azacytidine on acute GvHD are not connected probably with its influence on Th1/Th2-balance. Thus, the performed experiments confirm an important role of Th1/Th2-balance in development of acute GvHD.

INTEGRATED METHODS OF TERMITE CONTROL

Posted in 2021, BIOLOGY, Issue №6 (108) June 2021, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The current study uses the literature and experimental data to determine the rational methods of termite control. Among the abundance of anti-termite measures, there is no universal means of eliminating all types of termites, the vital activity of which depends on a variety of anthropogenic and biotic factors. In this regard, the search for effective ways to eliminate termites adapted to local conditions is an urgent task.

The article presents the results of attempts to eliminate Turkistan termite species. The study determines that the integration of control methods leads to an increase in the quality of protection against this pest.

When using an insecticide to control termites, their lifestyle is also taken into account. For an effective application of measures against the termites, the main task is to destroy the female, which is engaged only in reproduction. The female is usually located almost always underground and feeds on food delivered by worker termites.

The article presents new insecticidal compositions and methods of termite control as well as preventive measures during construction and repair work indoors. The developed insecticide contains borax, boric acid, sulfur-perlite-containing waste including millet, honey, and sugar as food bait. A mixture consisting of borax, boric acid, and sulfur-perlite-containing waste has a high nerve-paralytic effect. Termites gradually experience paralysis and die. Honey, sugar, and millet serve as food baits. In addition, millet, while getting into the body of termites, swells and closes the food passages, which additionally leads to their death.

It is recommended to use the insecticidal part of the proposed product (borax, boric acid, and sulfur-perlite-containing waste) for preventive measures by adding it to paint, construction adhesives, cement, and other mixtures.
