Many studies have shown the adverse effects of perfluorinated compounds (PFCs) on living organisms. PFCs include groups of perfluorinated sulfonic acids, perfluorinated carboxylic acids, fluorotelomer alcohols, high-molecular weight fluoropolymers and low-molecular weight perfluoroalkanamides. These compounds are chemically very stable and are highly resistant to biological degradation. Currently,...
Rye flours with extraction rate of 100% (wholemeal flour), 95% (brown flour), 90% (brown flour) and 70% (light flour) originated from Warko and Dańkowskie Złote rye varieties were prepared in order to compare the relation between flour extraction rates and content of bioactive compounds. The following compounds were analysed: total phenolic compounds (TPC), total flavonoids (TF), inositol hexaphosphate...
Germination (in light and dark, at 25°C, for up to 7 days) of cruciferous seeds was studied to determine the optimum conditions to maximize the synthesis of vitamin E in sprouts. In this study, the tocopherol content (α-T, ß-Т, y-T, δ-T) was examined in four species of cruciferous seeds: rapeseed (Brassica napus var. oleifera), white mustard (oleiferaSinapis alba L.), radish (Raphanus sativus L.),...
The biological bases for the relation of the cereal grains low molecular weight antioxidants intake to the reduction of risk for chronic diseases caused by oxidative stress have been discussed in this article.
Przedtawiono przesłanki do powołania Instytutu Chemicznej Przeróbki Węgla oraz przebieg jego działalności na przestrzeni 45 lat. Omówiono główne tematy badań naukowych i eksperymentalnych, a także osiągnięcia Instytutu w okresie jego istnienia. Podano również zamierzenia na przyszłość.
W artykule przedstawiono argumenty za racjonalnym wykorzystywaniem węgla jako surowca do produkcji paliw płynnych. Autor uważa za niezbędne podjęcie prac badawczych w dziedzinie przetwórstwa węgla, szczególnie wobec wzrastających cen ropy naftowej i wyczerpywania się jej światowych zasobów.
This review deals with selected recently used analytical methods for determining the antioxidant activity of compounds being investigated as well as total antioxidant capacity of the biological samples.
