Vitamin A status during pregnancy is important to maternal and infant health.
Serum retinol is transported by retinol binding protein (RBP), which has one high-affinity binding site for retinol; consequently, the molar ratio of retinol to RBP in the circulation is 1 to 1. In...
Inadequate vitamin A status has been a potential nutritional problem for some segments of the US population, particularly children and the poor.
The deuterated-retinol-dilution (DRD) technique provides a quantitative estimate of total body stores of vitamin A. However, it is not known whether the technique can detect changes in vitamin A po...
Vitamin A supplementation of mothers postpartum may improve infant health, not only by increasing vitamin A delivery to the infant through breast milk but also by increasing delivery of milk immune...
Chemopreventive agents developed to be used in a moderate-risk but otherwise healthy population need to be both efficacious and to have minimal adverse effects.
Two German sisters aged 14 and 17 y were admitted to the Tübingen eye hospital with a history of night blindness. In both siblings, plasma retinol binding protein (RBP) concentrations were below th...
Biesalski et al (1) present a novel case of 2 sisters aged 14 and 17 y with very low plasma retinol concentrations (0.19 mmol/L) and plasma concentrations of retinol binding protein (RBP) below the...
Deuterated retinol dilution (DRD) gives quantitative estimates of total body stores of vitamin A.
Background: Retinol-binding protein 4 (RBP4) is a novel adipokine that induces insulin resistance in mice. Studies in humans have shown a correlation between serum RBP4 and insulin resistance in obese...
Background: Vitamin A may influence gastric carcinogenesis through its essential role in controlling cell proliferation and differentiation. However, epidemiologic studies of vitamin A, retinol (prefo...
Increased rates of death from asbestos related diseases have been reported for people previously employed in the mining and milling operations at Wittenoom (Western Australia), and people who lived in...
The conventional deuterated-retinol-dilution (DRD) technique provides a quantitative estimate of total body stores of vitamin A in humans. The procedure requires equilibration of serum deuterated reti...
The objectives were to identify and evaluate all individual cases of retinol toxicity published in the scientific literature that assessed the thresholds and symptoms induced by high intakes of retino...
The quantitative determination of the conversion of β-carotene to vitamin A in humans can be accomplished by using a stable-isotope reference method. This approach provides in vivo metabolic informati...
