Vertical transport velocity of fine particles of aluminum smelter emissions.

In this study, the average values of vertical velocity of particles emitted from an aluminum smelter in the surface layer of the atmosphere were estimated using a semi-empirical method. The method is based on regression analysis of the horizontal profile of pollutants measured along the selected direction using moss bioindicators. The selection of epiphytic mosses was carried out in 2013 in the zone of influence of a metallurgical industry enterprise in the city of Kandalaksha, Murmansk region.

Redox regulation of the NLRP3-mediated inflammation and pyroptosis.

The review considers modern data on the mechanisms of activation and redox regulation of the NLRP3 inflammasome and gasdermins, as well as the role of selenium in these processes. Activation of the inflammasome and pyroptosis represent an evolutionarily conserved mechanism of the defense against pathogens, described for various types of cells and tissues (macrophages and monocytes, microglial cells and astrocytes, podocytes and parenchymal cells of the kidneys, periodontal tissues, osteoclasts and osteoblasts, as well as cells of the digestive and urogenital systems, etc.).

[Crista galli pnevmatization: prevalence and clinical significance].

Objective: Determine the frequency of (crest of the rooster) pneumatization and the presence of communication of the pneumatized with the paranasal sinuses.

Material And Methods: Computed tomography data of the paranasal sinuses of 251 patients. The patients' age ranged from 23 to 70 years.

[Interaction between the gut microbiota and oral antihyperglycemic drugs].

The gut microbiome is the largest microbial habitat in the human body. The main functions include obtaining energy from complex food fibers, maturation and formation of the immune system, intestinal angiogenesis, restoration of epithelial damage to the intestine, development of the nervous system, protection against pathogens, etc. It is also known that a number of drugs can cause changes in the composition of the intestinal microflora, and intestinal bacteria, in turn, produce a number of enzymes and metabolites that can chemically change the structure of drugs, leading to more side effects, and in some cases to positive changes.
