We showed in a recent study that topical retinyl palmitate prevented UV-B-induced DNA damage and erythema in humans. Given that retinyl palmitate is a precursor of retinoic acid, the biological form of vitamin A that acts through nuclear receptors, w

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.

In hairless mice, epidermal vitamin A (retinol and retinyl esters) is strongly decreased following a single exposure to UVB. Here, using the same mouse model, we studied the effects of UVA on epidermal vitamin A content, lipid peroxidation, and CRBP-

We have developed a new model using liposome-encapsulated fluorescent probes, aiming at assessing both the physical and the biological protection provided by filter molecules such as those incorporated in sunscreens. The fluorescent indicator Indo-1

The 9-cis-retinoic acid (9cRA) is an endogenous ligand of retinoid X nuclear receptors (RXRs). Although the epidermis contains five times more RXRs than RARs, little is known on the activity of topical 9cRA. In order to circumvent surface isomerizati

This paper introduces a nonlinear observer for quadratic maximal order polynomial systems. A link is made between robust stabilization techniques of systems with structured uncertainties and nonlinear observer design for the considered nonlinear syst

The present study was designed to explore if *etinaldehyde, a natural metabolite of vitamin A, has any biologic activity and is tolerated by human skin. Biologic activity was shown by the induction of cellular retinoic acid-binding protein type 2 (CR

Epidermal fatty acid-binding protein (E-FABP) was isolated from human skin and purified to homogeneity. Its molecular mass was estimated to be 15 kDa and the pI of non-denaturing protein was 5.6. Scatchard-plot analysis revealed one class of binding

Cellular retinoic acid-binding proteins (CRABPs) might exert a physiological function by controlling the intracellular levels of free retinoic acid. The aim of this study was to analyze the relative expression of CRABP-I and CRABP-II in lesional (LPS
