[Main epidemiological indicators of type 1 diabetes mellitus in children in the Russian Federation for 2014-2023].

Background: Type 1 diabetes mellitus (T1DM) is the most common form of diabetes mellitus in childhood, where, unlike in adults, it accounts for more than 90% of all cases of diabetes. The constant change in the epidemiology of T1DM with significant differences in populations and regions requires systematic data collection and analysis for timely monitoring of T1DM trends.

Aim: Analysis of the main epidemiological indicators of T1DM in children in the Russian Federation over the past 10 years - from 2014 to 2023.

Colloidal nanoparticles of sodium polygalacturonate prepared by nanoprecipitation.

Polygalacturonic acid (PGA), being the backbone of pectins, governs their aggregation that is widely applied in industry. The PGA aggregation was studied by dynamic and static light scattering within a limited space of sodium polygalacturonate nanoparticles obtained by nanoprecipitation (drop-wise addition of alkaline solution of PGA to an ethanol bath). With increasing buffer's pH from 4.

The effect of organic matter humification (aromaticity and oxidation degree) on structural and nanomorphological characteristics of humic nanocomposites of metallic platinum.

Background: It has been previously found that humic substances (HSs) can serve as the environmentally benign non-toxic agent for the preparation of magnetic and noble metals nanoparticles that are increasingly used in biomedicine. The structure of HSs and, hence, their synthetic potential depend on the source of their origin. Thus, humification character, determined by conditions and duration of complex transformation of organic remains in HSs can evidence their structure, in particular their aromaticity and oxidation degree.

Selenium Nanocomposites Having Polysaccharid Matrices Stimulate Growth of Potato Plants in Vitro Infected with Ring Rot Pathogen.

The influence of nanocomposites (NC) of selenium in matrices of arabinogalactan (Se/AG) and starch (Se/St) on in vitro vegetation of potato plants, peroxidase activity, and reactive oxygen species has been thoroughly studied. It has been shown that these nanocomposites of selenium have antimicrobial effect to the phytopathogenic bacterium Clavibacter michiganensis ssp. sepedonicus (Cms).

Smart colloids containing ensembles of gold nanoparticles conjugated with κ-carrageenan.

We study colloids of nanobiocomposites (NBC) containing Au nanoparticles (NP) obtained by reduction of gold precursor with functional groups of κCAR. The AuNPs content was changed from 2.0 to 5.
