The preruminant calf model was used to evaluate the effects of mild heat treatment on the serum and tissue accumulation of alpha- and beta-carotene from carrots. Twenty-four 1-wk-old Holstein male calves were assigned to one of four groups and fed a milk replacer diet. Negative control animals received no additional supplement. The three remaining groups(More)
Concentrations of preformed vitamin A and five individual carotenoids (alpha-carotene, beta-carotene, cryptoxanthin, lutein and lycopene) were determined in liver, kidney and lung tissue from 20 autopsies of subjects ranging in age from 4 mo to 86 y. Total carotenoid concentrations in liver tissue were always greater than in kidney or lung tissue within the(More)
We complete the program indicated by the Ansatz of D'Hoker and Phong in genus 4 by proving the uniqueness of the restriction to Jacobians of the weight 8 Siegel cusp forms satisfying the Anstaz. We prove dim[Γ 4 (1, 2), 8] 0 = 2 and dim[Γ 4 (1, 2), 8] = 7. In each genus, we classify the linear relations among the self-dual lattices of rank 16. We extend the(More)
This study evaluated the preruminant calf as an animal model for the study of human carotenoid metabolism. Fifteen newborn male Holstein calves were fed a carotenoid-free milk replacer diet to maintain them in the preruminant state. After a 7-d adjustment period, three calves were killed and 12 calves received a single oral dose (20 mg) of beta-carotene in(More)
Carotenoids from carrots and tomatoes were separated with high-performance liquid chromatography (HPLC) and capillary supercritical fluid chromatography (SFC). All trans alpha- and beta-carotene were separated from their respective cis-isomers with capillary SFC. Carotenoids extracted from tomatoes included xanthophyll, lycopene and beta-carotene, while(More)
