Retinol palmitate, an analog of vitamin A, plays multiple roles in the nervous system, including neural differentiation, axon outgrowth, and neural patterning, and is also an antioxidative agent and thereby potential neuroprotectant for brain ischemia. The present study aimed at

Overuse of vitamin A as a dietary supplement is a concern in industrialized countries. High-level dietary vitamin A is thought to shift immunity to a T helper 2 (Th2)-dominant one, resulting in the promotion of allergies. We have been studying

High-dose vitamin A influences glucose and lipid profile; however, the possible effects of moderate doses (25,000 IU/d) are conflicting. We aimed to compare the effect of vitamin A supplementation on several anthropometric and biochemical variables between obese and non-obese women.

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

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

We determined the kinds and amounts of vitamin A compounds (retinol and various retinyl esters) circulating in serum and stored in liver and other selected tissues of ferrets, using high-performance liquid chromatography. The concentration of total retinyl esters in serum

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
