Authors:   Kuban State Agrarian University named after I.T. Trubilina, Sallom Audai , Khadzhidi A. E.
Published: March 2021

To remove nitrates from the water of water supply systems, the polyvinyl / chitosan compound (PVA / CS) was studied. Optimal conditions for the absorption of nitrates on PVA / CS were investigated using antisurfaces. The results of the study showed that the mixture of polymers PVA / chitosan CS is an effective absorbent material for removing nitrates from water: the maximum concentration of solid phase nitrate was 0.5 mg / g at a pH in the range from 3 to 6; contact time was 70 minutes at a dose of adsorbent 2 g / l. These conditions were applied to the study of the equilibrium and kinetic adsorption of nitrates on (PVA / CS). Adsorption data are described by Langmuir and Freindlich models. The maximum concentration of solid phase nitrate calculated by the Langmuir model for (PVA / CS) was 92.59 mg / L. Nitrate mobility was analyzed on pseudo-adsorbents of the second pseudo-class, this relates to the nature of chemical adsorption.

Published: March 2021

The article presents an analysis of the effect of pinealon on free radical processes and the level of expression of the SOD1, GPX4 and GSR genes in the rat hippocampus in a model of streptozotocininduced diabetes (type I diabetes mellitus). It has been established that when modeling diabetes in the hippocampus, intensification of radically radical processes is observed: the level of prooxidants increases, the level of antioxidants decreases, as well as the level of expression of antioxidant genes. With the introduction of pinealone in dosages of 50 or 100 ng/kg in the model of diabetes mellitus, the pro-antioxidant balance shifts towards a decrease in the production of free radicals and an increase in antioxidant protection. Pinealon at a dosage of 100 ng/kg is more effective.

Analysis of special features of the reproductive system of so-iuy mullet Planiliza haematocheila (Temminck & Schlegel, 1845) females from the Azov and Black Sea Basin at the end of the winter season, 2019, has been conducted using the size of oocytes as its basis. Individual differences in distribution of oocyte sizes during the period of trophoplazmatic growth have been identified. Following the estimation of ordered series of oocyte sizes during the period of trophoplazmatic growth, the median and percentile values have been calculated; they can be used as reference values for qualitative characterization of ordered series for oocyte diameter in an individual specimen, using the empirical median, calculated for the respective specimen, as a basis. It has been found out that the sizes of trophoplazmatic growth oocytes, which are utilized during the spawning period of the current year, and, therefore, the degree of gonad maturity have individual characteristics independent of the age of an individual, of its length and weight, and of the content of reserve and bioactive substances in its tissues and blood.
