Incontinentia pigmenti achromians (IPA), first reported by Ito (Ito 1952), is a rare disease, involving the skin, hair, eyes, central nervous system, and musculoskeletal system. The cutaneous manifestations consist of macular hypopigmented whorls, streaks, and patches in a bilateral or unilateral distribution affecting almost any portion of the body surface. Central nervous system dysfunction, ...

the present study is designed to evaluate the application of a simple method for rapid identification of malassezia furfur among other malassezia spp. based on production of a brownish-red pigment and its diffusion into the medium containing l-tryptophan as a sigle source of nitrogen.  91 strains of malassezia (20% m. furfur , 2% m. sympodialis , 5% m. obtosa and 73% m. globosa ) isolated from ...

Pigment Red3 was synthesized and chemically treated by sulphonation. The treatment, affected the surface chemistry and the shape of pigments. The effects of reaction time, temperature, Solvent/Pigment ratio and Acid/Pigment ratio were examined on the treated pigment. The investigation of experimental design based on Tauguchi method, was carried out. To assessment of treated particles, UV-visibl...

Background: Many common cancers, such as prostate, breast, and colon, are caused by harmful substances and compounds contained in processed foods, including nitrite-treated meats. The aim of this study was to investigate the possibility of replacing sodium nitrite with Monascus purpureus pigment in sausage and to assess its antimicrobial, antioxidant, color, and sensory properties. Methods: The...

background and objectives : halophilic bacteria produce a variety of pigments, which function as immune modulators and have prophylactic action against cancers. in this study, colorful halophilic bacteria were isolated from solar salt lake and their pigments was extracted in optimal environmental conditions and compared with the pigments of halorubrum sodomense atcc 33755. materials and methods...
