Background Low vitamin A status and suboptimal milk vitamin A concentrations are
problems in many populations worldwide. However, limited research has been done on …

Background Vitamin A concentrations in breast milk are related to maternal vitamin A intake
and status. Objectives Our objective was to identify conditions under which vitamin A specific …

Background Many applications of the Simulation, Analysis and Modeling software use data
on the fraction of an orally administered tracer dose (FD) in plasma; thus, researchers must …

Background Previous compartmental models describing and quantifying whole-body vitamin
A (VA) metabolism have been developed from plasma retinol kinetic data after human …

Major strides have been made globally to eradicate blindness due to vitamin A (VA)
deficiency, but VA status assessments are still important for monitoring intervention …

Background Retinol isotope dilution (RID) indirectly estimates vitamin A (VA) status.
Multicompartment modeling of RID data is used to refine study designs and equations to …

Abstract Background Inadequate vitamin A (VA) intake is common among lactating women
in many communities worldwide, but high dose VA supplementation of postpartum women is …

ABSTRACT Background Measuring vitamin A (VA) status during lactation is required to
inform dietary recommendations. Limited data exist on VA stores in women. Objectives Our …

Background Mathematical modeling of theoretical data has been used to validate
experimental protocols and methods in several fields. Objective We hypothesized that …

Background An optimal blood sampling time for application of the retinol isotope dilution
(RID) method for predicting vitamin A total body stores (TBS)(ie, vitamin A status) has not …
