RELEVANCE OF DETERMINATION OF BARBITURIC ACID DERIVATIVES BY CHEMICAL AND TOXICOLOGICAL ANALYSIS ON EXAMPLE OF CYCLOBARBITAL
The relevance of the chemical and toxicological analysis for derivatives of barbituric acid are due to common poisoning with these substances and in a mixture with other toxicologically important drugs [4], [5], [6]. The basis of the expert assessment of poisoning with derivatives of barbituric acid is a qualitative determination of the drug in the human body, considering the circumstances of the case and the clinical picture of poisoning; however, it is possible to quantify the detected drugs and their metabolites. A transparent scheme of chemical-toxicological analysis was compiled and optimized in forensic chemical expert studies of biological objects to improve the diagnosis of poisoning with derivatives of barbituric acid.
Read MoreFEATURES OF ACTIVE BEZYMYANNYY STRATOVOLCANO FORMATION ON KAMCHATKA
The paper highlights the results of a study of volcanic processes on a large active Bezymyannyy stratovolcano, located on the Eastern mountain range of Kamchatka, in the Klyuchevskaya group of volcanoes of the Holocene age. This is one of the most active volcanoes in the world, characterized by continuous short-term explosive eruptions with powerful emissions of ash material, accompanied by lava flows and the formation of extrusions. This volcano became world-famous on March 30, 1956, among Soviet and foreign volcanologists, when there was a catastrophic eruption, which in the geological literature was called “directed explosion” or “Bezymyannyy type eruption.” In addition to volcanic structures, peculiar volcanic-sedimentary deposits of the volcano were also studied, represented by the so-called tephroids, which are the product of the movement and re-eruption of volcanic-clastic material of eruptions.

The paper presents the results of the study of morphology, structure, mineral and chemical composition of uroliths from the Madhya-Pradesh state (India) and uroliths from the Tomsk Region (Russia). The authors studied the morphology of uroliths and their structural features, as well as the mineral composition and relationships between minerals. The comparison of the morphology, structure and mineral composition of uroliths obtained from Indian patients showed that the uroliths from the Indian state of Madhya-Pradesh are similar to those from the Siberian region.

The data from the pharmacological and epidemiological study of FORSAIT-SD2 show that patients with diabetes mellitus (DM) type 2 have an average of 2 to 6 concomitant pathologies, and global statistics also indicate that depressive have an increasing share among comorbid pathologies. The lack of identification and timely correction of psychoemotional disorders in patients with diabetes mellitus type 2 affects not only the patient’s quality of life but also the effectiveness of sugar-lowering pharmacotherapy. In turn, hypoglycemic pharmacotherapy can affect the development or progression of depression. This paper discusses the aspect of daytime sleepiness and depressive disorders in patients with diabetes mellitus type 2 with metformin therapy as part of multicomponent pharmacotherapy.
Read MoreSTUDYING POSSIBILITY OF USING VEGETABLE PHENOLIC COMPOUNDS TO PREVENT DAMAGE TO MEAT PRODUCTS
The paper discusses the results of studies of the antioxidant activity of water extracts obtained from various parts of the plants of the family of Lamiaceae (Labiaceae) – field mint, garden mint, lemon balm, purple basil. It was found that water extracts from plants of the family Lamiaceae – field and garden mint, violet basil, and lemon balm can be used as safe antioxidants in the technology of vegetable oils and fat-containing products, such as minced meat. It was shown that the extracts from violet basil have the highest antioxidant activity, and the extracts of garden mint have the least activity. The effect of the number of plant extracts on meat safety was also studied.
The extracts from plants of the Lamiaceae family containing phenolic compounds of various classes are not inferior to synthetic antioxidants in their antioxidant activity. Studies conducted on the feasibility of using extracts from some plants of the family of Lamiaceae as antioxidants for fats and fat-containing products show that these extracts can be used to prevent or slow down oxidative processes, leading to a decrease in nutritional value and shelf life of food products.
Read MoreCOMPARATIVE ANALYSIS OF SOIL AND VEGETATION IN DALNIYE ZELENTSY VILLAGE AND CITY AREA OF MURMANSK
This paper briefly presents the description and comparative characteristics of soils selected in 2019 at eight sites near the Dalnie Zelentsy village (East Murman) and on the territory of the city of Murmansk. It was revealed that the vegetation at the sites is represented by typical tundra species, subjected to anthropogenic impact and succession. Most soils are acidic Al-Fe-humus peaty podzols. By granulometric composition, all soil samples are sandy loam. Soil organisms live mainly in the upper organogenic horizon. Ciliata is the basis of soil biocenosis. The most common infusoria are the genera Colpoda, Stylonychia and Oxytricha sp. A study of the vegetation, thickness, and structure of the soil profile, and an assessment of the contemporary biodiversity of the protist fauna, may be important for monitoring the soil cover and determining the direction of soil processes.

Applying two methods (visual assessment of the area of the perceived color surface and the area of the horizontal projection of the color spot on the peony bush) the authors selected the most decorative cultivars species (Appassionata, Ijun’, Lyudmila Mironova, Mechta S.P. Koroleva, Ogni Ufy, Polyarnik 8, Sabantuy, Utro Rodiny, Ufimets) as a result of assessing the decorativeness of 20 peony varieties selected by the South Ural Botanical Garden-Institute, a structural unit of the Federal State Budget Scientific Institution of the Ufa Federal Research Center of the Russian Academy of Sciences according to the method developed in the Botanical Garden of Moscow State University. These varieties are recommended for further implementation in the production and landscaping of cities and towns of the Republic of Bashkortostan.
Read MoreONTENTS OF LIPID-HYDROCARBON COMPLEX COMPONENTS IN MOLLUSCS IN SEVASTOPOL OFFSHORE STRIP (BLACK SEA)
The offshore strips of coastal cities are of a great economic and recreational importance. They concentrate pollutants from both a coast and a sea, while at the same time providing the most significant contact of people with the marine environment. An important role in the interaction with pollutants belongs to coastal overgrown communities of macrophytes. As for the Sevastopol region, brown alga Cystoseira barbata (Stackh.) C.Agardh (1920) forms the vast underwater marine growth; its thalli are inhabited by various representatives of gastropods and bivalves, such as Rissoa splendida (Eichwald, 1830), Bittium reticulatum (da Costa, 1778), Gibbula divaricata (Linnaeus, 1758), Tricolia pullus (Linnaeus, 1758), Parvicardium exiguum (Gmelin, 1791), Mytilaster lineatus (Gmelin, 1791). The paper presents data on the content of total lipids and petroleum hydrocarbons in these mollusks. The content of total lipids in mollusks was determined by a color reaction with a phosphovaniline reagent followed by densitometry, and petroleum hydrocarbons by infrared spectrometry. The results of the studies allow us to recommend the most common mollusks Rissoa splendida living on the Cystoseira as new indicator species for assessing low levels of oil pollution in the offshore strip of the Black Sea coast of the Crimean peninsula. At the same time, these hydrations can be used to assess the microbiological flows of petroleum hydrocarbons in predicting the environmental consequences of oil pollution of coastal waters.

Due to the shortage of drinking water in various regions of Russia, groundwater and places of its exposure are of great interest. The results of the latest inventory of the springs in the Samara region were obtained in 2002. But, the need for a new study has become topical again. Some of the springs are in an unsatisfactory condition, require reclamation and care; others were missed during the previous inventory or formed recently. We have examined 18 springs of the Kamyshlinsky district of the Samara region, 6 of which were revealed for the first time. Flora of springs and water protection zones includes 202 species of vascular plants and 105 taxa of algae. There are 19 rare plant species recorded in the vegetation. Most springs require immediate protection.
