Many food raw materials contain natural antioxidants which exert control of oxidative processes in the living cells. Among antioxidative agents are found enzymes such as superoxide dismutase, glutathione peroxidase and glucose oxidase-catalase. Among naturally occurring non-enzymic antioxidants are carotenoids, especially astaxanthin (e.g. in fish), tocopherols in oils and other phenolic compou...
Characteristics of Selected Antioxidative and Bioactive Compounds in Meat and Animal Origin Products
A series of 5-sulphanyl derivatives of 1-Benzyl-2-alkyl-4-nitro-1H-imidazoles (5-9) were prepared by the coupling method of 3-(1-Benzyl-2-ethyl-4-nitro-1H-imidazole-5ylsulfanyl)propanoic acid (4) with appropriate amino acid ester hydrochloride, in the presence of hydroxybenzotriazole (HOBT) and DCC. Compounds (10-12) and (13) were similarly synthesized using appropriate amino alcohols, and 1-su...
The question as to how far the development of chronic diseases in humans depends on diet still remains open. Simultaneously, epidemiological studies suggest the consumption of a flavonoids rich diet might decrease the risk of degenerative changes and certain diseases. The intake of this group of compounds as to quality and quantity depends on dietary habits and a widespread presence of querceti...
Propolis is a gum-like product which are gathered by bees from various plants, and which vary in color from light yellow to dark brown. It is known that the propolis have antibacterial, anticarcinogenic, and immunostimulating biological activities. Parts of these activities are probable due to the antioxidative effect of some compounds which occur in relatively higher concentrations in propolis...
Vitus labrusca L. is a fragrant grape variety that widely grown in our country and the world. In addition to being consumed as table grape, it also by processing into different products such wine, vinegar, molasses. This fruit its residues, revealed after product, are rich phenolic compounds. The residues of can be evaluated due their bioactive potential. this study, characteristics V. Samsun w...
BACKGROUND Liver disorder was associated with alcohol consumption caused by hepatic cellular damages. Opuntia ficus-indica fruit extracts (OFIEs), which contain betalain pigments and polyphenols including flavonoids, have been introduced as reducing hangover symptoms and liver protective activity. OBJECTIVE To evaluate hepatoprotective activity of OFIEs and isolated compounds by high-speed co...
The antioxidative activities of 12 medicinal plants and the compounds isolated from them were investigated using the thiocyanate method to evaluate inhibitory effects on lipid peroxidation in the linoleic acid system. The peroxide levels gradually increased during incubation in the presence of linoleic acid over 3 days, and most of the plants inhibited lipid peroxidation. In particular, of the ...
Lucilia sericata maggots have beneficial properties; however, their protective effects on burn wounds have yet to be fully elucidated. In the present study, a deep second‑degree burn rat model was used to investigate the burn wound healing properties of aqueous extract of maggots (MAE). The anti‑inflammatory, antioxidative and antibacterial activities were examined. In addition, the protein exp...
BACKGROUND While dysmetabolism is common in patients with chronic kidney disease (CKD) and associated with mortality, the mechanisms mediating these changes are unclear. New data implicate fibroblast growth factor (FGF)-19 as a possible entero-hepatic modulator of lipid metabolism. METHODS Using samples previously gathered as part of a randomized placebo-controlled study of antioxidative ther...
