Skin diseases associated with the depletion of stratum corneum lipids and stratum corneum lipid substitution therapy.
The skin is the largest organ of the body, whose main function is to protect the body against the loss of physiologically important components as well as harmful environmental insults. From the inside to the outside, the skin comprises three major structural layers: the hypodermis, the dermis and the epidermis. The epidermis contains four different sublayers, the stratum corneum (SC), stratum g...

متن کاملIn vitro permeation of nickel salts through human stratum corneum.
Allergic contact dermatitis due to nickel salts is common. It is therefore important to measure the permeation of these salts through the stratum corneum (SC), the primary rate-limiting domain in skin. An advanced diffusion system and analytical techniques now enable better measurement of the flux than was possible in earlier experiments. Human SC was prepared by trypsinization of dermatomed ca...
متن کاملCutaneous Water Loss and Lipids of the Stratum Corneum in Dusky Antbirds, a Lowland Tropical Bird
The stratum corneum, the outer layer of the epidermis, consists of flattened cells embedded in a matrix of lipids, primarily cholesterol, free fatty acids, ceramides, and cerebrosides. The stratum corneum forms a barrier to water vapor diffusion through the skin. In birds, the skin limits excessive water loss at thermoneutral temperatures, but also serves as a vehicle for thermoregulation durin...
متن کاملPhenotypic flexibility in cutaneous water loss and lipids of the stratum corneum.
When vertebrates invaded land during the Carboniferous period, they were exposed not only to new ecological opportunities but also to a desiccating environment. To maintain cellular water homeostasis, natural selection modified the integument of pioneering terrestrial animals, enabling them to reduce water loss through the skin. In desert environments, where ambient temperatures (T(a)) can reac...
