Dermoscopy of pigmented skin lesions: results of a consensus meeting via the Internet.
The virtual Consensus Net Meeting on Dermoscopy represents a valid tool for better standardization of the dermoscopic terminology and, moreover, opens up a new territory for diagnosing and managing pigmented skin lesions.
Oxygen in acute and chronic wound healing
An overview on the role of oxygen in wound healing and chronic wound pathogenesis, a brief insight into systemic and topical oxygen treatment, and a discussion of the roles of wound tissue oximetry are provided.
Postzygotic HRAS and KRAS mutations cause nevus sebaceous and Schimmelpenning syndrome
The results indicate that nevus sebaceous and Schimmelpenning syndrome are caused by postzygotic HRAS and KRAS mutations, which may predispose individuals to the development of secondary tumors in nevous nevi.
Hyper-IgE syndromes.
Cytokines, chemokines and growth factors in wound healing
This review aims to keep the reader up to date with selected important and novel findings regarding growth factors, cytokines and chemokines in wound healing.
Improvement of early recognition of lentigo maligna using dermatoscopy.
Skin ageing
The formation of reactive oxygen species and the induction of matrix metalloproteinases reflect the central aspects of skin ageing and the detection of its mechanisms have furthered the development of various therapeutic and preventive strategies.
Photo-oxidative killing of human colonic cancer cells using indocyanine green and infrared light
According to the present results, photoactivated ICG seems to kill colonic cancer cells due to the generation of singlet oxygen and the subsequent formation of lipid peroxides, which might present a promising photosensitizer for PDT; first clinical results confirm these findings.
Singlet oxygen generation by UVA light exposure of endogenous photosensitizers.
In aerated solution, riboflavin and FMN generate more singlet oxygen than exogenous photosensitizers such as Photofrin, which are applied in photodynamic therapy to kill cancer cells.
