[The dynamics of provision of population of the Russian Federation with otorhinolaryngologists in 2018-2023].

The most acute problem of state health care system is shortage of medical personnel, both physicians and paramedics. The purpose of the study is to assess dynamics of personnel support with otolaryngologists in medical organizations of the Russian Federation for 2018-2023. The retrospective analytical descriptive study was carried out using continuous method based on studying dynamics of personnel support with otolaryngologists in the Russian Federation in general, Federal Okrugs and particular Subjects of the Russian Federation for 2018-2023.

Synthesis and characterization of selenium nanoparticles stabilized with oxyethylated alkylphenol (neonol) for potential modification of fabric materials.

This work demonstrates the first time synthesis of selenium nanoparticles (Se NPs) stabilized with neonol. The synthesis method was optimized using a multifactorial experiment with three input parameters. The most stable sample had a radius of 15 nm and a ζ-potential of -36.

[Cellular engineering in periodontology].

An overview of various cell engineering techniques being developed for modern conservative and reconstructive periodontology is presented. The accelerated development of cellular engineering technologies poses to medicine and, in particular, periodontics, the task of early implementation of the results of such experiments into patient management protocols. The main groups of promising techniques that are closest to practical healthcare are: isolation and use of stem cells; synthesis of biologically active (inductive) signaling molecules; development of scaffolds that ensure three-dimensional tissue growth.

Sustainable detergent-disinfectant agent based on whey mineralizate and silver nanoparticles for cleaner production in dairy industry.

Detergents and disinfectants for dairy industry must meet a variety of characteristics, including low toxicity, high antibacterial activity, and excellent rinsing of pollutants from working surfaces. This work presents an innovative detergent-disinfectant agent based on whey mineralizate and silver nanoparticles (Ag NPs), which allows reducing production costs and ensuring high cleanliness of treated surfaces compared to analogues. For this purpose, a method for obtaining sols of Ag NPs stabilized with didecyldimethylammonium bromide (Ag NPs-DDAB) was developed and optimized using neural network algorithms.
