Low-dose trans-resveratrol induce poly(ADP)-ribosylation-dependent increase of the PPAR-γ protein expression level in the in vitro model of non-alcoholic fatty liver disease.

An effect of low-dose resveratrol treatment on lipid metabolism and pro-inflammatory processes has been studied, using an in vitro model of Non-Alcoholic-Fatty Liver Disease. The model system consisted of lipid-loaded monolayer cultures of hepatocytes (Hepa1-6) and macrophages (RAW264.7), as both cell types are present in the liver.

[Transformation of lignins from grape solids during alcoholic fermentation].

Conversion of lignins contained in solid parts of Rkatsiteli grapes (crests, seeds, and skin) during alcoholic fermentation by wine yeast in Reader's medium was studied. Various species of wine yeast were used: Saccharomyces oviformis, S. vini Kakhuri 42, S.

[Formation of pyrogallol ether during oxidative destruction of oak lignin with air oxygen].

Formation of pyrogallol ether during thermal oxidation of oak (Quercus iberica L.) lignin in the presence of air oxygen was investigated. A model reaction demonstrated that the substance identified by us as pyrogallol ether (1,2-dioxy-3-methoxybenzene) is derived from syringic aldehyde.
