...Steven Horsburgh; Nicola Fullard; Mathilde Roger; Abbie Degnan; Stephen Todryk; Stefan Przyborski; Steven O’Reilly The skin is the largest organ of the integumentary system and possesses a vast number of functions. Due to the distinct layers of the skin and the variety of cells which populate each...

... cell (VSMC) pathophysiology by examining VSMCs differentiated from progenitors found in skin. Approach and results : Skin-derived precursors (SKPs) were cultured from biopsies ( N =164, ∼1 cm 2 ) taken from the edges of surgical incisions of older adults ( N =158; males 72%; mean age 62.7 ± 13 years...

... biological processes, and this situation has been documented in active vitiligo skin. Tyrosinase activity is impaired by excess H 2 O 2 through oxidation of methionine residues in this key melanogenic enzyme. Mechanisms for repairing this oxidant damage are also damaged by H 2 O 2 , compounding the effect...

We have described previously a dysregulation of collagen synthesis in cultured smooth muscle cells from saphenous veins and in dermal fibroblasts from the skin of patients with varicose veins, suggesting a systemic defect in their...

...Richard WELLER Nitric oxide (NO) is involved in several processes in the skin, including wound healing, pigmentation and regulation of apoptosis. Pharmacological intervention with NO donors appears to be a promising treatment for conditions such as diabetic ulceration. In this issue of Clinical...

... in decomposition rate between 19 and 37 °C. In the forearm of eight normal male subjects, we found that D -SNAG produced a significant dose-dependent vasodilator effect ( P =0.001) with good reproducibility (19%) on repeated testing. We propose that delivery of NO from D -SNAG to the forearm skin...

To overcome this, a selectively permeable, hydrophilic polyester co-polymer membrane system (Sympatex™) has been identified that can be placed...
