Recent studies have shown that reassembled micelles formed by caseinates and purified casein fractions (α(s)- and β-casein) bind to hydrophobic compounds, including curcumin, docosahexaenoic acid, and vitamin D. However, limited research has been done on the binding of hydrophobic compounds

The intestine efficiently incorporates and rapidly secretes dietary fat as chylomicrons (lipoprotein particles comprising triglycerides, phospholipids, cholesterol, and proteins) that contain the apolipoprotein isoform apoB-48. The gut can store lipids for many hours after their ingestion, and release them in

Nanocapsules containing poly(d,l-lactide) shell and retinyl palmitate core have been prepared by the pre-formed polymer interfacial deposition method. Dynamic light scattering measurements yielded an average hydrodynamic diameter of ∼220nm and a polydispersity index of ∼0.12. Small-angle neutron scattering experiments revealed

Retinyl esters, a storage form of vitamin A, concentrate in the epidermis, and absorb ultraviolet radiation with a maximum at 325 nm. We wondered whether these absorbing properties of retinyl esters might have a biologically relevant filter activity. We first

Previously, we have presented a method for quantifying beta-carotene bioavailability based on analysis in serum, following administration of (13)C-labeled beta-carotene. Because stool samples can be collected noninvasively, we have now extended the method to measure the bioavailability based on measurements

To alleviate vitamin A (VA) deficiency (VAD) in Senegal, understanding the relationship between VA status of lactating women and their 6-mo-old infants is important. This study measured 6-mo-old infants' VA intake from human milk and assessed the VA status of

In 11 patients with IIB hyperlipoproteinemia we studied fasting lipids, lipoproteins, lipoprotein-modifying enzymes, and postprandial lipid metabolism after a standardized oral fat load supplemented with vitamin A before and 12 weeks after treatment with fenofibrate, a third-generation fibric acid derivative.

Exacerbated postprandial lipid responses are associated with an increased cardiovascular risk. Dietary proteins influence postprandial lipemia differently, and whey protein has a preferential lipid-lowering effect. We compared the effects of different whey protein fractions on postprandial lipid and hormone responses

There are inverse relationships between HDL cholesterol and plasma triacylglycerol concentrations in normal and in hypertriglyceridemic individuals. To investigate the interactions between triacylglycerol-rich lipid particles and HDL, a lipid emulsion model of the triacylglycerol-rich lipoproteins was prepared. When emulsion particles
