The biological properties of dihydroquercetin (DHO) modified by including it into the ring of beta-cyclodextrin (beta-CD) to give it more water-soluble properties have been investigated. It was shown that the peroral administration of the DHQ/beta-CD complex provides a long increase of DHQ concentration in rat blood (up to 7.5 h), and, unlike pure DHQ, the(More)
Differential scanning calorimetry was used to study the influence of the flavonoid taxifolin (dihydroquercetin) on the temperature-dependent phase transition of dimyristoylphosphatidylcholine multilamellar liposomes. Taxifolin was added to organic solution of the lipid during the procedure of liposomes preparation (addition from-within) or to a suspension(More)
It is demonstrated by thin-section that S. faecalis cells (Strain BKM-B6) have no inner membranes, and their plasma membranes do not show any invagination into the cytoplasm. It is established that B and A fracture faces of the membranes in the intact bacteria, protoplasts, osmotic shock and sonicated membrane fractions contain uniformly distributed(More)
We studied the interaction with liposomes and the antioxidant activity of flavonoid (quercetin, catechin, taxifolin) complexes with iron (III). It was found that the lipophilicity of complexes depends on an iron:flavonoid ratio and grows at a ratio of 1 to 1, while complexes in a 2:1 ratio were the most effective to slow down the lipid peroxidation and(More)
Intravenous administration of emulsions of some perfluorochemicals (PFCs) are followed by lung gas-exchange alterations, lung inflation and animal death. The emulsion toxicity can be caused by both low aggregation stability of the emulsion in the blood stream and appearance of the additional gas pressure in alveoli as a result of difference in the rates of(More)
