    Vitiligo & Pigmentation Institute of Southern California, 5670 Wilshire Boulevard, #650, Los Angeles, CA 90036, USA.
    Vitiligo is an autoimmune disorder that involves the interplay between oxidative stress and the immune system. Preliminary observations suggest that the presence of gluten in the diet may play a role in vitiligo development in some patients, but to date vitiligo-specific diets have not been studied. The role of oral supplements, including vitamins, minerals, and botanicals, is increasingly being investigated as adjuncts to conventional medical treatment due to their antioxidant and immunomodulatory activity.

    Pharmacokinetics and Pharmacodynamics of Afamelanotide and its Clinical Use in Treating Dermatologic Disorders.
    Clin Pharmacokinet 2017 Jan 6. Epub 2017 Jan 6.
    Stadtspital Triemli, Institute of Laboratory Medicine, Zurich, Switzerland.
    Afamelanotide, the first α-melanocyte-stimulating hormone (MSH) analogue, synthesized in 1980, was broadly investigated in all aspects of pigmentation because its activity and stability were higher than the natural hormone. Afamelanotide binds to the melanocortin-1 receptor (MC1R), and MC1R signaling increases melanin synthesis, induces antioxidant activities, enhances DNA repair processes and modulates inflammation. The loss-of-function variants of the MC1R present in fair-skinned Caucasians are less effectively activated by the natural hormone. Read More

    Localized thermal tumor destruction using dye-enhanced photothermal tumor therapy.
    Lasers Surg Med 2015 Jul 5;47(5):452-61. Epub 2015 Jun 5.
    Department of Oral and Maxillofacial Surgery, University Medical Center Hamburg-Eppendorf, Hamburg, Germany.
    Background And Objective: In an attempt to develop a new therapeutic approach for highly localized thermal destruction of tissue targets that lack natural pigmentation, the potential of in-vivo dye-enhanced photothermal therapy (PTT) was investigated. PTT involves the application of an exogenous absorber, which accumulates in metabolically active tissues, followed by non-invasive light irradiation, using appropriate wavelengths, exposure durations, and irradiances. The chromophore used, palladium(II) octabutoxynaphthalocyanine (PdNc(OBu)8 ), strongly absorbs in the near infrared wavelength range which thus permits good penetration depth of the exciting light.
