Sudden cardiac death associated with fatty liver disease.

Background: Fatty liver disease or steatotic liver disease (SLD) affects 25% of the global population and has been associated with heart disease. However, there is a lack of postmortem studies in the context of sudden cardiac death (SCD).

Objectives: To investigate the relationship between SLD and SCD.

Application of -based test systems for the assessment of genotoxic effects of environmental radioactivity of undisturbed mountain soils (Aragats Massif, Armenia).

Plant test systems are a sensitive way to detect the genetic effects of various contaminants in environmental compartments: water, soil and sediments. Biotesting of the genotoxicity of soil samples with various activity concentrations of naturally occurring (Ra, Th, K) and artificial (Cs) radionuclides in soil, from the territory of the Aragats Massif (Armenia) was carried out with the application of the micronucleus (Trad-MСN) and stamen hair mutation (Trad-SHM) bioassays of (clone 02) model test-object in the soil - plant system. Undisturbed soil sampling was performed in the southern slopes of the Aragats Massif, from different altitudes (from 1000 to 3200 m above sea level).

Modeling, synthesis and in vitro testing of peptides based on unusual amino acids as potential antibacterial agents.

Currently non-protein amino acids and synthetic peptides are widely used as blocks in drug design. Many proteases are of great interest for pharmacology due to their key role in various pathologies. Bacterial collagenase (EC 3.

DNA Damage in Moderate and Severe COVID-19 Cases: Relation to Demographic, Clinical, and Laboratory Parameters.

The ability of the SARS-CoV-2 virus to cause DNA damage in infected humans requires its study as a potential indicator of COVID-19 progression. DNA damage was studied in leukocytes of 65 COVID-19 patients stratified by sex, age, and disease severity in relation to demographic, clinical, and laboratory parameters. In a combined group of COVID-19 patients, DNA damage was shown to be elevated compared to controls (12.
