Soot aerosols emitted during combustion can affect climate by scattering and absorbing the sunlight. Individual soot particles are fractal aggregates composed of elemental carbon. In the atmosphere, these aggregates acquire coatings by condensation and coagulation, resulting in significant compaction of the aggregates that changes the direct climate forcing of soot.

Moreover, THz radiation induced E.

For accurate species-level identification of microorganisms, researchers today increasingly use a combination of standard microbiological cultivation and visual observation methods with molecular biological and genetic techniques that help distinguish between species and strains of microorganisms at the level of DNA or RNA molecules. The aim of this work was to identify microorganisms from the ICG SB RAS Collection using an integrated approach that involves a combination of various phenotypic and genotypic characteristics. Key molecular-genetic and phenotypic characteristics were determined for 93 microbial strains from the ICG SB RAS Collection.

- MALDI-TOF mass spectrometry is an efficient method for identifying microorganisms due to its speed and accuracy, but it lacks a universal reference database for mass spectra.
- This study implements a geometric approach to process mass spectrometry data, enabling the creation of a web-based application that improves identification methods.
- The research shows that new algorithms, which analyze full spectra without peak-picking, achieve accuracy comparable to existing software, with resources and data made available online for further use.
Background: Our aim was to study changes in the serum proteomic profile in coronary atherosclerosis.
Methods: The study involved two groups of patients: 1) men with coronary heart disease and coronary atherosclerosis (n = 15); 2) control (n = 15): men without coronary heart disease. The object of this study was blood serum.
