Copper deficiency does not affect conversion of β-carotene to vitamin A in rats
Autor: John G. Bieri, Anne Dulin, J.Cecil Smith
Publikováno v: Nutrition Research. 15:589-594
The central cleavage of β-carotene to vitamin A purportedly involves a dioxygenase that may be copper dependent. Therefore, the purpose of this study was to determine the effect of copper (Cu) deficiency on the conversion of β-carotene to vitamin A

Copper deficiency fails to affect vitamin A status
Autor: John G. Bieri, J. Cecil Smith, Anne M. Dulin
Publikováno v: Nutrition Research. 12:1365-1372
The effect of dietary copper (Cu) deficiency on vitamin A status as measured by serum and liver vitamin A was examined. Weanling male Sprague Dawley rats were randomly assigned by weight to one of four groups of 11–12 animals. Group 1 was fed a Cu

Publikováno v: The American Journal of Clinical Nutrition. 55:1120-1125
ABSTRACI’ We determined serial changes in four major plasma carotenoid fractions (a-carotene, /3-carotene, lutein/ zeaxanthin, and lycopene) in 30 men consuming defined daily doses of carotenoids from foods (broccoli, carrots, or tomato juice) or f

[4] Association of carotenoids with human plasma lipoproteins
Autor: Beverly A. Clevidence, John G. Bieri
Publisher Summary This chapter discusses the association of carotenoids with human plasma lipoproteins. The majority of circulating carotenoids are associated with lipoproteins, which serve as plasma transport vehicles. The spectrum of carotenoids fo

Ineffectiveness of Testosterone and FSH in Maintaining the Vitamin A Deficient Rat Testis
Autor: John G. Bieri, George L. Catignani
Publikováno v: Annals of Nutrition and Metabolism. 24:255-260
The combined administration of follicle-stimulating hormone and testosterone to sexually mature male rats whose testes were in the early stages of damage from retinol deficiency did not prevent the continued degeneration of the germinal epithelium. I

Determination of Individual Carotenoids in Human Plasma by High Performance Liquid Chromatography
Autor: John G. Bieri, J. Cecil Smith, Ellen D. Brown
Publikováno v: Journal of Liquid Chromatography. 8:473-484
A high performance liquid chromatography procedure using an internal carotenoid standard, echinenone, is described. The method uses a C-18, reverse-phase column, an isocratic solvent (acetonitrile:methylene chloride:methanol, 70:20:10) and requires o
