Rhododenol (Rhododendrol)-induced leukoderma: an objective way to ascertain normalization of the skin
Monday, December 15th, 2014This study suggests an objective way to follow-up of rhododenol-induced vitiligo by skin absorption spectrum analysis A word on Rhododenol (Rhododendrol): Rhododendrol (Rhododenol) is is derived from the white birch tree it inhibits tyrosinase activity and melanin synthesis Vitiligo-like lesions were observed and in march 2014, 14000 cases were reported in Japan alone In this […]
A tool to study Rhodenol (Rhododendrol) induced leucoderma (Vitiligo-like lesions)
Sunday, December 14th, 2014Rhododendrol (Rhododenol, RD) created a big problem in Japan, when 14000 induced cases of vitiligo-like lesions were reported. It is known that Rhodoendol is cytoxic against melanocytes in a Tyrosinase dependent way cytotoxicity The authors suggest a new mouse model for the study of this effect: hk14-scf/HRM Tg Mice become albino (fully depigmented) through suppression […]
Protection against Ultraviolet Light (UVB) with Phloretin Sulfate
Sunday, December 14th, 2014The phenolic compound phloretin: is a member of dihydrochalcones is found in apples and apple juice Phloretin 3,3 disulfonate (P33D) is obtained after its sulfonation with sulfuric acid Pure concentrated Phloretin sodium sulfonate was added to Human Cell cultures which were irradiated with UVB 20 mJ/cm2 Results show that reduced amounts of P33D were found […]
Molecules AGAINST Tanning in the cosmetic world
Sunday, December 14th, 2014In early 20th century Europe, it was considered a mark of “low-class”, as it was assimilated with outdoor professional activities.

Excimer Laser treatment to stop scratching ?
Saturday, December 13th, 2014The excimer laser is a 308nm device used in the treatment of localized lesions of psoriasis and vitiligo. In this study done on mice (“dry skin model”), atopic dermatitis (AD) was induced with application of “dermatphagoides farina body” ointment in shaved area twice a week for 3 weeks ANTIHYPERINNERVATION. Results after one excimer session show: […]
How skin pH could affect disease activity in Atopic Dermatitis
Saturday, December 13th, 2014Atopic Dermatitis (AD), beyond filaggrin mutations is better understood, but still remains (at the time of publication) full of gaps. pH alterations in AD are a matter of debate, but they do have an effect on its symptoms (itching) and appearance. This study shows molecular as well as physical alterations in AD. KLK5 can catalyze […]

Young Skin or when the Cell Nucleus can communicate with the Cytoplasm (Cytosol)
Saturday, December 13th, 2014The nuclear membrane separates the nucleus from the cytosol (cytoplasm) several proteins shape are part of its different layers. its role is to maintain mRNA and protein trafficking Lamin A and C are 2 of the main proteins. Its coding gene LMNA is mutated in the premature aging syndrome called the Hutchinson-Gilford progeria syndrome Progerin […]
