Ceramides metabolism and impaired epidermal barrier in cutaneous diseases and skin aging: focus on the role of the enzyme PNPLA1 in the synthesis of ω-O-acylceramides and its pathophysiological involvement in some forms of congenital ichthyoses☆

open access: yesOilseeds and fats, crops and lipids, 2019
The outermost layer of the skin, the stratum corneum, is essential for the protective barrier functions of the skin. It results from the stacking of corneocytes, the dead flattened cells resulting from epidermal terminal differentiation of underlying ...

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

open access: yesBMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

Culture of Dermatophytes Upon Stratum Corneum

open access: yes, 1972
An in vitro method of culturing dermatophytic spores on stratum corneum alone is described. The stratum corneum is stripped onto a translucent adhesive tape and fixed to a microscope slide.

Quantification of Palmar and Digital Epidermal Thickness and Sweat Duct Density

open access: yesClinical Anatomy, EarlyView.
ABSTRACT Palmar digital skin, with its high density of epidermal sweat glands and unique stratum corneum, derives its autonomic innervation from peripheral nerves. Understanding the changes to these structures could serve as objective proxy markers following peripheral nerve injury and interventions to promote regeneration.

Mechanical properties of stratum corneum studied by nano-indentation

open access: yes, 2002
Stratum corneum acts as a barrier to protect our body, as well as a pathway for conducting skin sensations. Understanding the mechanical properties such as elasticity, yield stress, of stratum corneum is important to improve and develop new products in ...

6-Hydroxy-4-sphingenine in human epidermal ceramides.

open access: yesJournal of Lipid Research, 1994
The solvent-extractable lipids of human epidermal stratum corneum consist predominantly of ceramides. In addition two non-extractable ceramides are chemically bound to the stratum corneum protein. One of the bound ceramides, constituting 50% of the bound

Exploring Cerumen as an Alternative Matrix for Drug Detection and Quantification: Method Development and Application in Clinical Samples

open access: yesDrug Testing and Analysis, EarlyView.
An LC–MS/MS method was developed for the detection of 33 psychoactive medications in cerumen (earwax) and applied to the samples of 60 psychiatric inpatient volunteers. The findings highlighted the utility of cerumen as an innovative biospecimen in clinical toxicological analysis.

Cell Layer and Density of Negro and Caucasian Stratum Corneum

open access: yes, 1974
Stratum corneum from Negroes and Caucasians has been compared with respect to facility of tape stripping, numbers of cell layers, and density. Significantly more strips were required for removal of stratum corneum, and significantly more cell layers were

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
