Electrochemical characterization of human skin by impedance spectroscopy: the effect of penetration enhancers.

Abstract:

:The electrochemical properties of human cadaver skin were studied in a diffusion cell with impedance spectroscopy as a function of time in the absence and presence of penetration enhancers dodecyl N,N-dimethylamino acetate and Azone. An improved electrochemical model of skin is presented, and combining the novel model with modern fractal mathematics, the effect of enhancers on the surface of skin is demonstrated. The enhancers appeared to open new penetration routes and increase the ohmic resistance, capacitive properties, and fractal dimension of skin, which means a rougher or more heterogeneous surface.

  • Transport Mechanisms for the Nutritional Supplement β-Hydroxy-β-Methylbutyrate (HMB) in Mammalian Cells.

    abstract:PURPOSE:β-Hydroxy-β-methylbutyrate (HMB), a nutritional supplement, elicits anabolic activity in muscle. Here we investigated the mechanism of HMB uptake in muscle cells. METHODS:Murine muscle cells (C2C12) and human mammary epithelial cells (MCF7) were used for uptake. As HMB is a monocarboxylate, focus was on monoca...
