How stiff is skin?

How stiff is DNA?

The natural stiffness of DNA, which contributes to the interactions of the many proteins involved in its biological processing and packaging, also plays an important role in modern nanotechnology. Here we report new Monte-Carlo simulations of deformable DNA molecules of potential utility in understanding the behavior of the long, double-helical polymer in the tight confines of a cell and in the...

Stiff skin syndrome - Case report Síndrome stiff skin - Relato de caso

Stiff skin syndrome is a rare scleroderma-like disorder of unknown etiology characterized by stone-hard indurations of skin, mild hypertrichosis and limited joint mobility. No effective treatment has yet been found. Exercises and rehabilitative therapy are important in maintaining the patient's quality of life. The authors present a case of a two-year-old boy with progressive skin hardening sin...

The stiff skin syndrome: case series, differential diagnosis of the stiff skin phenotype, and review of the literature.

BACKGROUND Stiff skin syndrome is a sclerodermalike disorder that presents in infancy or early childhood with rock-hard skin, limited joint mobility, and mild hypertrichosis in the absence of visceral or muscle involvement, immunologic abnormalities, or vascular hyperreactivity. OBSERVATIONS We describe 6 children who fit criteria for stiff skin syndrome. A review of the clinical range of thi...

Skin translucency: what is it and how is it measured?

Objective: Translucency is the most nebulous attribute that describes ideal skin appearance. Physics would define an object as translucent if light can partially pass through it. However, skin translucency is not only about light passing through the skin. P&G research shows that the perception of skin translucency is a holistic term that involves the integration of skin color, glow and texture....
