Polyphenol compounds were analysed and storage stability determined of cold-pressed cakes from one non-genetically modified (non-GM) flax variety Linola and two GM lines: W92 line with overexpressed flavonoid biosynthesis pathway and GT line with overexpressed glycosyltransferase. The 20 g samples of each cake were stored in oxygen-free and dark conditions for 3 (T3) and 7 (T7) months at 4 and 21...
Flax is a valuable source of fibers, linseed and oil. The compounds of the latter two products have already been widely examined and have been proven to possess many health-beneficial properties. In the course of analysis of fibers extract from previously generated transgenic plants overproducing phenylpropanoids a new terpenoid compound was discovered. The UV spectra and the retention time in UPLC...
Miejscowe oddziaływanie wstrząsów i uderzeń mechanicznych na organizm człowieka różni się od oddziaływania drgań mechanicznych. W niniejszej pracy przedstawiono metodykę, stanowisko pomiarowe oraz wyniki pomiarów mocy drgań wstrząsów i uderzeń mechanicznych dla sygnału drganiowego typu szum biały ograniczony pasmowo oraz sygnału uderzeniowego w postaci przebiegu funkcji sin. Dodatkowo, w celu rozpoznania,...
W artykule przedstawiono stanowisko do badań i metodę wyznaczania mocy drgań, wstrząsów i uderzeń mechanicznych wnikających przez rękę operatora i pochłanianych w jego organizmie. Moc ta jest wyznaczana na podstawie części rzeczywistej widma wzajemnego siły i prędkości, mierzonych na styku dłoni z rękojeścią z zastosowaniem specjalnego adaptera. Przedstawiono wyniki badań dla 13 sygnałów testowych,...
The applications of cell cultures and transgenic plants in several aspects of modern biotechnology are reviewed. The usefulness of cell cultures in biosynthetic pathway investigation, micropropagation, development of new varieties, genetic mapping and gene functioning analysis and industrial production of bioactive compounds are pointed out. The emphasis of this review is also laid on scientific aspects...
