In modern clinical practice, the main methods for correcting elevated serum cholesterol levels are drugs that block the activity of the enzyme hydroxymethylglutaracyl-CoA-reductase (HMG-CoA-reductase) – statins or drugs that inhibit the absorption of cholesterol and sterols in the intestines ezetimibe. All hypocholesterolemic drugs are rather expensive and have side effects, Читати далі

In the review, on the example of aerobic spore-forming bacteria, the problems of the development and ontogenesis of the bacterial cell are considered along with the possibilities of influencing the course of these processes. The characteristics of the main concepts "growth", "differentiation", and "development" as independent processes with their dynamic Читати далі

The achievements of modern enzymology have greatly expanded the possibilities of practical use of enzymes, primarily in medicine and the food industry, which is due to their advantages over chemical catalysts: selectivity and stereospecificity of action, the possibility of achieving high rates of conversion of substrates under relatively mild technological Читати далі

Influenza A virus takes a stable position in annual acute respiratory disease outbreaks during the autumn-winter period. Antiviral drugs for influenza infection help significantly ease the course of the disease and prevent complications, but there is still no drug to which none of the circulating strains would be resistant. Therefore, Читати далі

Recently, nanocomposite materials containing nanoparticles of metals such as silver, copper and zinc oxide have attracted most attention due to their pronounced pharmacological properties, such as antimicrobial, antiviral, antiinflammatory, immunomodulatory ability and high stability in extreme conditions. Polyelectrolyte complexes based on polymers of natural origin, namely polysaccharides of chitosan and Читати далі

Despite the key role in biogeochemical processes and in the functioning of terrestrial ecosystems, yeasts of Antarctic regions still remain insufficiently studied. The study and analysis of the composition of Antarctic microbial communities remains relevant and is carried out using molecular biological approaches. The investigation of their resistance to toxic Читати далі

Fungi of the Myrothecium genus are well-known producers of macrocyclic trichothecenes, characterized by the acute toxic effect on warm-blooded organisms and fungicidal action against a wide range of fungi. At the same time, as established by us earlier, M. cinctum (current name Striaticonidium cinctum) 910 shows a wide spectrum of Читати далі

Protease-producing representatives of Bacillus have been isolated from various environments such as the rhizosphere, soil, sewage, food, waste, and saline environments (sea water, marine sediments, hypersaline lakes, salty food, soda lakes, etc.). However, today, little is known about the characteristics of proteases in representatives of the genus Bacillus, isolated from Читати далі

Xanthomonas fuscans subsp. fuscans is known as an obligate phytopathogen — the pathogen of small brown spot of beans that gradually expands the range of host plants and spreads worldwide on legumes. The review provides data on the problems of the pathogen’s systematics and its change depending on the new Читати далі

The rare occurrence of viable bacteriophages is an issue in studying bacterial-phage systems of the phytopathogenic bacterium Pectobacterium carotovorum subsp. carotovorum (Pcc). Aim. To obtain viable bacteriophages by activating pseudolysogeny of the Pcc strains. Methods. To obtain bacteriophage F66, isogenic clones of Nalr mutants of strains Pcc 66A and Pcc Читати далі
