Among birds, vultures show low concentrations of plasma carotenoids due to the combination of their large size, general dull colouration and a diet based on carrion. We recorded the concentration of each carotenoid type present in plasma of the Andean condor (Vultur gryphus) according to age and sex, that determine colour signalling and dominance hierarchies in the carcasses. We compared the ca...
Carotenoids and retinol are considered biomarkers of fruits and vegetables intake, and are of much interest because of their anti-inflammatory and antioxidant properties; however, there is inconsistent evidence regarding their protective effects against lung cancer. We conducted a meta-analysis of prospective studies of blood concentrations of carotenoids and retinol, and lung cancer risk. We i...
Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease. It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...
The increase in antioxidant capacity after wounding depends on the type of fruit or vegetable tissue
Wounding of fresh produce may elicit an increase in antioxidant capacity associated with wound-induced phenolic compounds. However, there have been no reports on the wounding response of different types of fresh produce. Changes in antioxidant capacity, total soluble phenolics, ascorbic acid, total carotenoids and total anthocyanins were evaluated after wounding in zucchini, white and red cabba...
BACKGROUND Published associations between dietary carotenoids and vitamin C and bladder cancer risk are inconsistent. Biomarkers may provide more accurate measures of nutrient status. OBJECTIVE We investigated the association between plasma carotenoids and vitamin C and risk of urothelial cell carcinoma (UCC) in a case-control study nested within the European Prospective Investigation into Ca...
The effects of oxygen supply on growth and carotenoids accumulation by Xanthophyllomyces dendrorhous were studied. Initial volumetric oxygen transfer coefficients (K(L)a) within the range 21.5-148.5 h(-1) had significant effects on growth and carotenoids accumulation, and an increase of the initial K(L)a value led to higher carotenoids, astaxanthin and biomass yields by X. dendrorhous. At an in...
We compared the carotenoid profile in GM papaya (Sunup) line to that of a non-GM one (Sunset). First, to identify major carotenoids in papaya, large-scale extraction was carried out with methanol. HPLC analyses of the methanol extracts revealed that both papayas mainly contained 5 pigments and no apparent difference was observed in the HPLC profiles. On the basis of LC/MS data and photodiode-ar...
