The investigation was carried out using mathematic analysis of variety features of the stem resistance for winter and spring wheat, barley, rye, t...

Matrix metalloproteinases (MMP) belong to the family of zinc metalloprotenases, whose function is related to the metabolism of the extracellular matrix proteins. These enzymes play an important role in the development of physiological processes such as morphogenesis, resorption and tissue remodeling, migration, adhesion, cell differentiation and proliferation, as well as in pathological conditions (rheumatoid arthritis, glomerulonephritis, periodontitis, ulceration of the cornea, etc.). To the first, the most stud...

Alzheimer`s diseases (AD) is the most common age-related dementia, being characterized by accumulation of extracellular amyloid plaques in AD brains. The principal constituent of these plaques are fibrils which are primarily composed of amyloid-? peptides (A?), with 39-42 amino acid residues in length, which are the proteolysis products derived from the amyloid precursor peptide (APP). Several factors, such as oxidative stress, inflammation, metal ions or genetic factors are associated with AD. Even if metal ions ...

The development of the most efficient technology is extremely important to synchronize work on the laying yielding strawberry parent plants. The main link here should be the material obtained in vitro. The most vulnerable element of in vitro technology is adaptation to non-sterile conditions, when it is very difficult to simultaneously control a large number of factors and when very large plant losses are possible. The fundamentally new method of adapting microplants to hydroponics has been tested and allows us to...

Amiodarone (AMD) is an antiarrhythmic agent included in the 2nd class according to the biopharmaceutical classification of drug substances. The oral bioavailability of AMD in conventional pharmaceutical formulations exhibits large interindividual variations due to the rapid dealkylation of the molecule to desethylaminodarone (inactive metabolite) and due to low hydrosolubility. The complexation of the drug substance in the central cavity of various kinds of cyclodextrins is one of the most effective methods for op...
