Bone marrow adipocytes (BMAds) constitute the most abundant stromal component of adult human bone marrow. Two subtypes of BMAds have been described, the more labile regulated adipocytes (rBMAds) and the more stable constitutive adipocytes (cBMAds), w

The purpose of this study was to investigate the mechanisms by which carotenoids [xanthophylls vs. β-carotene(β-C)] are taken up by retinal pigment epithelial (RPE) cells. The human RPE cell line, ARPE-19, was used. When ARPE-19 cells were fully di

In presence of oleate and taurocholate, differentiated CaCo-2 cell monolayers on membranes were able to assemble and secrete chylomicrons. Under these conditions, both cellular uptake and secretion into chylomicrons of β-carotene (β-C) were curvili

Bone samples extracted from embalmed cadavers are commonly used as controls in the study of bone. The effects of embalmment on the molecular composition of bone are unknown. The objective of this study was to determine the effect of embalmment on the

Health benefits of fruits and vegetables could be attributed to the presence of a large diversity of phytochemicals, including carotenoids. The bioactivities of carotenoids greatly depend on their bioavailability that could be modulated by the presen
