The etiologic agent(s) that was responsible for the 1981 toxic oil syndrome [TOS] epidemic in Spain has not been identified. Liquid chromatography combined with atmospheric pressure ionization tandem mass spectrometry was used for the analysis of oils associated with TOS. Analyses focused on measuring 3-(N-phenylamino)-1,2-propanediol [PAP], the 3-oleyl ester of PAP [MEPAP], and the 1,2-di-oley...

Three types of monofloral honey from the Andean regions of Ecuador (Avocado, Eucalyptus, and Rapeseed honey) were analyzed to determine their floral origin, physicochemical parameters, chemical composition, antioxidant capacity, and their capacity to reduce in vitro bacterial biofilms. The chemical composition varied considerably depending on floral origin. The highest values of bioactive compo...

Skřivanová V., Tůmová E., Englmaierová M., Chodová D., Skřivan M. (2017): Do rearing system and freerange stocking density affect meat quality of chickens fed feed mixture with rapeseed oil? Czech J. Anim. Sci., 62, 141−149. Recently, consumers have paid an attention to animal-friendly meat. The aim of the study was to evaluate the meat quality of breast muscles in indoor and free-range chicken...

Although rapeseed (Brassica napus L.) is known to be affected by waterlogging, the genetic basis of waterlogging tolerance by rapeseed is largely unknown. In this study, the transcriptome under 0 h and 12 h of waterlogging was assayed in the roots of ZS9, a tolerant variety, using digital gene expression (DGE). A total of 4432 differentially expressed genes were identified, indicating that the ...

Kinetic study of methanolysis of rapeseed oil in two phase liquid-liquid systems is performed in a batch reactor observing substances concentration gradient for process optimization. Concentration of initial substances, temperature of the system and stirring speed have significant effect on transesterification of rapeseed oil. They are considered as dominant factors to be optimized. Transesteri...

Near-infrared spectroscopy (NIRS) was used as a rapid and nondestructive method to determine the fatty acid composition in intact seed samples of rapeseed (Brassica napus L.). A total of 349 samples (about 2 g of intact seeds) were scanned in the reflectance mode of a scanning monochromator, and the reference values for fatty acid composition were measured by gas-liquid chromatography. Calibrat...

OBJECTIVE Despite the great number of substances produced by the skincare industry, very few of them seem to truly have an effect on the skin. Therefore, given the social implications surrounding physical appearance, the search for new bioactive compounds to prevent or attenuate skin ageing and enhance self-image is a priority of current research. In this context, being rich in valuable compoun...

The present work describes the effects of winter and spring genotypes of rapeseed (PF7045/91, Okapi and Opera), explants (cotyledons and hypocotyls), light, different kinds and concentrations of auxins [Naphthylacetic acid (NAA) and 2, 4dichlorophenoxyacetic acid (2, 4-D)], presence of cytokinin [benzyladenine (BA)] and different concentrations of micro and macro elements (MS and 1/2MS) on call...
