HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with...

Population-Specific Genetic Markers of Prostate Cancer Risk in Kazakh Men: Association Analysis of 102 SNPs and Risk Prediction Modeling

Background/Objectives: GWASs have identified more than 250 prostate cancer (PCa) predisposition loci, predominantly in European and partly Asian cohorts. The Kazakh population is markedly under-represented in international genetic studies, limiting existing risk models. This stud...

Extracellular and Intracellular Bacterial Compounds in the Synthesis of Inorganic Particles: Silver Nanoparticles

The primary objective of this study was to compare the contribution of cellular and cell-free filtrates of Serratia marcescens ATCC 9986 to the synthesis of silver nanoparticles, followed by a determination of the inhibitory activity on growth of S. marcescens and E. coli of the...

Starch as a Polymer-Based Medium Modifier to Analyze Enzyme Activity under Conditions Close to Intracellular Media: Butyrylcholinesterase as a Model Enzyme

Abstract The study demonstrates the possibility of using starch to model macromolecular crowding and intracellular medium. A kinetic approach is used to reveal specific functioning of butyrylcholinesterases from different sources in the starch medium. In the study solutions, the...
