Yellow maize with high b-carotene is an effective source of vitamin A

, 2011
Background: The bioconversion efficiency of yellow maize b-carotene to retinol in humans is unknown. Objective: The objective of this study was to determine the vitamin A value of yellow maize b-carotene in humans. Design: High b-carotene–containing yellow maize was grown in a hydroponic medium with 23 atom% 2H2O during grain development.

Dietary Carotenoids and Cognitive Decline: A Longitudinal Study Among Chinese Middle-Aged and Older Adults. [PDF]

Health Care Sci
Higher intake of dietary carotenoids was associated with slower cognitive decline. The strongest protective association was observed for moderate carotenoid intake. Total carotenoid intake exhibited a non‐linear association with cognitive decline. ABSTRACT Background This study examined the association between dietary intakes of total and specific ...

Vitamin A equivalency of ß-carotene in healthy adults: limitation of the extrinsic dual-isotope dilution technique to measure matrix effect [PDF]

, 2009
Data on the vitamin A equivalency of ß-carotene in food are inconsistent. We quantified the vitamin A equivalency (¿g) of ß-carotene in two diets using the dual-isotope dilution technique and the oral¿faecal balance technique.

Genes involved in carotene synthesis and mating in Blakeslea trispora [PDF]

, 2008
Mating of Blakeslea trispora and other molds of the order Mucorales requires the interaction of mycelia of opposite sex, (+) and (-), leading to the development of specialized structures and to an enhanced accumulation of beta-carotene.
