“…The research and development of high-performance nanostructured adsorbent sensors for selective detection of trace elements and heavy metals in various media and materials used in agriculture is promising [1][2][3][4][5][6][7][8][9]. Another promising area is the use of nanoparticles to improve the productivity of crops [10,11] and the production of seed dressing agents [4,12,13]. A promising direction for the practical application of nanotechnology in agriculture is the use of metal nanoparticles for pre-sowing treatment of agricultural plant seeds since the pre-sowing treatment of seeds is one of the simplest ways to improve the quality of seed and increase crop yields.…”

Within the framework of this study, the effect of nanoparticles of the essential trace element selenium stabilized by Polyvinylpirrolidone (PVP) C15 (8 ± 2 kDa) and ascorbic acid on the germination of barley seeds has been studied. Selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid, characterized by a spherical shape, monodisperse size distribution, and a diameter of about 70 ± 5 nm, were obtained by the chemical reduction method. The experiment compared the effect of selenium nanoparticles and selenous acid on seed germination. The positive effect of preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid on the length of roots and shoots, the number of roots, and the percentage of seed germination has been revealed. It was determined that the highest percentage of Hordeum vulgare L. culture seed germination was achieved using a preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid at a concentration of of 4.65 µg/mL. Analysis of the results showed that selenium in the form of nanoparticles has an order of magnitude that is less toxic than in the form of selenous acid. The study of morphological and functional parameters during the germination of Hordeum vulgare L. seeds allowed us to conclude that selenium nanoparticles can be successfully used in agronomy and agriculture to provide plants with the essential microelement selenium, which is necessary for the normal growth and development of crops.

The aim of the study was to determine the effect of the inhibitor of janus kinase – baricitinib ("Olumiant") on the course of COVID-19. This drug baricitinib is able to suppress the systemic inflammatory response, which is one of the common causes of death in COVID-19, is an urgent problem of the study. The study was carried out in the Regional Specialized Budget Infectious Diseases Hospital of Stavropol (Russian Federation, Stavropol Region). In a multivariate analysis, it was shown that the use of baricitinib was associated with a decrease in the frequency of the primary endpoint of death/need for invasive lung ventilation. The use of baricitinib was quite safe, but in some patients there was an increase in the level of transaminases. No cases of hypercoagulation have been reported while taking baricitinib. It was found that patients with a normal BMI are more sensitive to therapy than those who are overweight.75% of patients in the first group had a temperature above 38.0oC. However, against the background of taking the standard treatment regimen and baricitinib, it was noted that the temperature stabilized during the day and did not rise again. Against the background of taking baricitinib, the elimination of the phenomena of respiratory failure and the refusal of an oxygen mask occurred 3.1 times more often than without baricitinib. The authors concluded that the use of baricitinib can be considered as an additional therapy for moderate forms of pneumonia in patients over 65 years or in patients with concomitant chronic diseases in order to suppress the reactions of systemic inflammation and the development of serious respiratory and other system lesions caused by COVID-19.

“…Before setting up the experiment, the laboratory animals underwent a seven-day quarantine, and then acclimatization in the experimental room for five days. The creation of treatment and comparison animal groups was performed by the pairs-analogues method [13][14][15][16][17][18][19]. Specification of the Virulence of Individual Cultures: The culture of the 2 nd passage, grown on a dense nutrient medium, was cleansed with 0.9% sodium chloride dilution.…”

This publication presents the results of studying the biosafety of microorganisms used for the development of a biological product-a litter destructor, both individually and in a joint composition. In the experiment, the culture of Stylonychia (Stylonychia mytilus) and laboratory animals (rabbits, mice, and rats) were used. Based on a series of preclinical studies, it was found that the studied microorganisms individually do not indicate any symptoms of virulence, toxigenicity, toxicity and do not give an affirmative counteraction to the formation of hemolysin. The results of the express method showed that the aqueous and acetone extracts obtained from the joint microbial composition did not have a detrimental effect on the culture of protozoa, the viability in all groups was 100.0%. The analysis of the dermonecrotic effect of the studied microbial preparation demonstrated that the studied extracts did not cause hemorrhage, hyperemia, peeling, edema, and other pathology indicating an inflammatory process on the skin of laboratory rabbits. Conducting an acute experiment confirmed the safety of the studied microbial consortium, since during the research the laboratory mice remained active, mobile, no signs of poisoning or other pathology were found, and the conducted pathoanatomical autopsy did not reveal lesions of the parenchymal organs of the laboratory test objects. In general, the results of the studies indicated that the investigated cultures of microorganisms and their joint composition in the composition of the biological product-destructor do not show a toxic impact on the body of lab test objects, which confirms their harmlessness.
