Journal ArticleDOI
Contributions of exercise, body composition, and age to bone mineral density in premenopausal women.
Lee Alekel,Jody L. Clasey,Patricia C. Fehling,Ronald M. Weigel,Richard A. Boileau,John W. Erdman,R. J. Stillman +6 more
TL;DR: It is suggested that walking and aerobic dance exercise may provide physically active premenopausal women with greater lumbar and femoral BMD than sedentary females.
Journal ArticleDOI
Determination of lycopene, α- and β-carotene and retinyl esters in human serum by reversed-phase high performance liquid chromatography
TL;DR: Analysis of serum from a hypercarotenemic anorexia nervosa patient and a person suffering from hypervitaminosis A are presented as examples of the clinical application of thisHPLC procedure.
Journal ArticleDOI
Testosterone and Food Restriction Modulate Hepatic Lycopene Isomer Concentrations in Male F344 Rats
Thomas W.-M. Boileau,Steven K. Clinton,Susan Zaripheh,Marcia H. Monaco,Sharon M. Donovan,John W. Erdman +5 more
TL;DR: The results suggest that androgen depletion and 20% food restriction increase hepatic lycopene accumulation and hypothesize an endocrine and dietary interaction, where higher androgen concentrations and greater energy intake may stimulate lycopenes metabolism and degradation.
Journal ArticleDOI
Interactions of oral β-carotene and canthaxanthin in ferrets
TL;DR: The results suggest that, at the doses given, a concurrent oral canthaxanthin dose has a specific antagonistic effect on the bioavailability of a beta-carotene dose in ferrets.
Journal ArticleDOI
Compartmental and noncompartmental modeling of 13C-lycopene absorption, isomerization, and distribution kinetics in healthy adults
Nancy E. Moran,Morgan J. Cichon,Ken M. Riedl,Elizabeth Grainger,Steven J. Schwartz,Janet A. Novotny,John W. Erdman,Steven K. Clinton +7 more
TL;DR: C-Lycopene combined with physiologic compartmental modeling provides a strategy for following complex in vivo metabolic processes in humans and reveals that postabsorptive trans-to-cis-lycopene isomerization, and not the differential bioavailability of isomers, drives tissue and plasma enrichment of cis-ly copene.
