INFLUENCE OF GROWTH REGULATORS ON THE MORPHOGENETIC ACTIVITY OF EXPLANTS DIOSCOREA NIPPONICA MAKINO AND THE FORMATION OF POLYPHENOLS

Posted in 2020, BIOLOGY, Issue № 06(96) June 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

We studied the effect of growth regulators on the morphogenetic activity of various explants of medicinal plants of the Dioscorea genus, as well as the formation of soluble phenolic compounds. The best results were shown on the nutrient medium with IAA (concentration of 5 mg/l). The intact plants Dioscorea nipponica Makino and the micro-clones induced on their basis are highly biosynthetic in a variety of phenolic compounds. Organ specificity for the accumulation of polyphenols characteristic of an intact plant is preserved in vitro but to a lesser extent.

Posted in 2020, BIOLOGY, Issue № 05(95) May 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

It is known that as a result of increased metabolism in athletes, a significant part of cholesterol is captured by cells that consume cholesterol for the synthesis of corticoid and steroid hormones, hematopoiesis, the formation of sebaceous glands and bile acids [4]. The dynamics of changes in the lipid profile as a result of physical activity indicate a change in the balance of the processes of anabolism and catabolism of total cholesterol and lipoproteins in the direction of strengthening the latter in student-athletes compared with non-athletes and sports veterans. This indicates a greater adaptive resource of the athletes ‘ body.

BIOLOGICAL PROPERTIES OF SOILS IN ANTHROPOGENICALLY DISTURBED BOREAL FORESTS OF AMUR RIVER REGION

Posted in 2020, BIOLOGY, Issue № 05(95) May 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Boreal forests carry out numerous global ecosystem functions; namely, the accumulation of carbon (C) in soils is one of the most important ones, and it goes during the process of biodestruction of plant litter. Forest fires and logging are the major anthropogenic violations of these forests; they lead to a significant violation of the biological properties of soils and, consequently, the ability of the ecosystem to biodegrade organic residues. The goal of this work is to study the physicochemical and biological properties of brown soil of larch forests affected by deforestation and fires. The studies were conducted in the northern part of the Amur Region in the larch forests of the foothills of the Tukuringra ridge. There is a significant change in soil acidity, the increase in coarse humus reserves, and increased soil moisture in the disturbed area, besides the thickness of forest litter in disturbed forests has increased. Due to the increased insolation, the soils of disturbed areas warm up more intensively in the spring and cool more intensely in the autumn. The number of oligotrophic microorganisms and exoenzymes involved in the decomposition of hard-to-reach organic substances in the soils of anthropogenically disturbed territories is much lower than the background. Thus, our studies show that fires and logging significantly alter the soil and plant conditions and biological properties of soils in boreal larch forests. Due to the disturbed biological functions of the soil, the easily degradable part of the litter is mineralized, and the remaining part accumulates in the form of rough humus. All together, this indicates a slowdown in the carbon cycle and humus formation in the disturbed forests of the boreal zone.

Posted in 2020, BIOLOGY, Issue № 05(95) May 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Disposal of sewage sludge is a global problem for modern cities. The presence of solid materials is the main problem when it comes to their usage as fertilizers. In the course of the vegetation experiments, sewage sludge from the Tyumen treatment facilities was studied as organic fertilizer as well as in soil composition. The introduction of sewage sludge into the soil at a dose of 3.5 t/ha had a positive effect on soil fertility and test culture plants. According to a number of indicators, the increase in doses had a negative impact on wheat seedlings. Sewage sludge in the composition of soils in the 1:1 and 2:1 ratio to the components had a negative impact on the root system of the test culture. An increase in the ratio of the components to sediment up to 3 and 4 parts influenced the plants of the test culture positively.

PHYSIOLOGICAL REACTION OF RHEOLOGICAL PARAMETERS OF ERYTHROCYTES IN PERSONS WHO STARTED REGULAR PHYSICAL TRAINING AFTER A LONG PERIOD OF LOW PHYSICAL ACTIVITY

Posted in 2020, BIOLOGY, Issue № 05(95) May 2020, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The rheological parameters of red blood cells largely determine microcirculation and metabolism in all tissues. The evaluation of their characteristics in people with low physical activity, who began to take moderate physical activity regularly, can help to reveal the mechanisms for optimizing the micro-rheological properties of red blood cells fully. The observation group consisted of 45 men of the second adulthood, who began regular classes in the athletics section 3 times a week, who previously had low physical activity. The control group consisted of 42 men of the same age who regularly visited the athletics section 3 times a week for at least ten years. The authors applied biochemical, hematological, and statistical research methods. After six months of physical training, people who previously had low physical activity noted the elimination of the imbalance of arachidonic acid metabolites, lowering cholesterol and acyl hydroperoxides with an increase in their total phospholipids. In 6 months, these individuals showed an increase in red blood cell-discocytes by 8.2% with a decrease in levels of 18.5% and 2.1 times, respectively, of reversibly and irreversibly changed red blood cells. It is clear that a gradual improvement in the cytoarchitectonic properties of red blood cells is typical for people of the second adulthood, who began regular physical activity after a long period of low physical activity, which improved their microcirculation processes and activated metabolism.
