Mechanical properties and barrier function of healthy human skin.
The aim of this study was to investigate the relationship between the mechanical properties and the epidermal barrier function of the skin in vivo. A suction cup device commonly used for measurement of skin mechanics was used to provide a defined stress to the skin using the ventral forearm in 16 healthy volunteers. The integrity of the barrier function was assessed by trans-epidermal water los...
متن کاملCeramides and barrier function in healthy skin.
Lipids in the stratum corneum are key components in the barrier function of the skin. Changes in lipid composition related to eczematous diseases are well known, but limited data are available on variations within healthy skin. The objective of the present study was to compare ceramide subgroups and ceramide/cholesterol ratios in young, old, male and female healthy skin. A total of 55 participa...
متن کاملPermeability barrier function of skin exposed to ionizing radiation.
OBJECTIVE To characterize the epidermal permeability barrier function of skin during exposure to ionizing radiation. DESIGN A prospective cohort study. SETTING University hospital medical center. PATIENTS Fifteen women receiving local radiation therapy (5000-6000 rad [50-60 Gy]) following breast-conserving surgery for breast cancer. MAIN OUTCOME MEASURES Clinical symptoms and transepide...
متن کاملImmunotopographical Differences of Human Skin
The immunological barrier of the healthy skin is considered to be unified on the whole body surface-however, recent indirect findings have challenged this dogma since microbial and chemical milieu (e.g., sebum, sweat, and pH) exhibit remarkable differences on topographically distinct skin areas. Therefore, in the present study, we performed whole transcriptomic and subsequent pathway analyses t...
متن کاملPostnatal ecdysis establishes the permeability barrier in snake skin: new insights into barrier lipid structures.
A competent barrier to transepidermal water loss (TEWL) is essential for terrestrial life. In various vertebrates, epidermal water barriers composed of lipids prevent excessive TEWL, which varies inversely with habitat aridity. Little is known, however, about the mechanisms and regulation of permeability relative to natal transition from the 'aqueous' environments of gestation to the 'aerial' e...
