Quantitative Genetic Analysis of Three Important Nutritive Traits in the Fruit of Avocado
Carlos L. Calderón-Vázquez,Mary L. Durbin,Vanessa E.T.M. Ashworth,Livia Tommasini,Kapua K. T. Meyer,Michael T. Clegg +5 more
TL;DR: Estimates of the heritability of carotenoids, b-sitosterol, and a-tocopherol content (the most biologically active form of vitamin E) in ripe avocado fruit are reported, and each is shown to have a sufficiently high heritability to predict successful marker-assisted selection.

Photoacoustic Determination of Non-radiative Relaxation Time of Absorbing Centers in Maize Seeds
TL;DR: In this article, the non-radiative relaxation times associated with different absorbent centers of corn seeds were determined by using PAS, using a frequency scan at different wavelengths (350 nm, 470 nm and 650 nm).
Journal ArticleDOI
Determination of Antioxidant Content and Capacity of Four Jordanian Fresh Citrus Fruits
TL;DR: This study aimed at comparing four fresh Jordanian citrus fruits for their antioxidant content and capacity (using two methods namely: Folin-Ciocaltaeu method and total flavonoids method) and capacity.

Can dietary beta-carotene materially reduce human cancer rates?
TL;DR: If dietary β-carotene is truly protective—which could be tested by controlled trials—there are a number of theoretical mechanisms whereby it might act, some of which do not directly involve its ‘provitamin A’ activity.

Identification, Quantification, and Relative Concentrations of Carotenoids and Their Metabolites in Human Milk and Serum
TL;DR: Thirty-four carotenoids, including 13 geometrical isomers and eight metabolites, in breast milk and serum of three lactating mothers have been separated, identified, quantified, and compared by high-performance liquid chromatography (HPLC)-photodiode array (PDA) detection-mass spectrometry (MS).
