Zinc oxide, which has photocatalytic activity, is used as a white pigment in cosmetics. With cosmetics containing zinc some sebum on the skin broken down by UV rays of sun. In this study, order to suppress activity oxide was added an aqueous solution sodium pyrophosphate and shaken, so that novel coated with phosphate having no prepared for use The chemical composition, powder properties, hue (...

We describe a blue/green inorganic material, Ba3(P1−xMnxO4)2 (I) based on tetrahedral MnO3− 4 :3d 2 chromophore. The solid solutions (I) which are sky-blue and turquoise-blue for x ≤ 0·25 and dark green for x ≥ 0·50, are readily synthesized in air from commonly available starting materials, stabilizing the MnO3− 4 chromophore in an isostructural phosphate host. We suggest that the covalency/ion...

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...

Thyroxine has been shown to accelerate the synthesis of carbamyl phosphate synthetase in the liver of Rana catesbdana. Stimulation of carbamyl phosphate synthetase synthesis by thyroxine appears to be relatively specific because of the following observations: (I) succinoxidase activity decreased during the time that carbamyl phosphate synthetase increased; (2) liver catalase responded more slow...

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...

phosphorus (p) is one of the most vital elements for all living organisms which acts as aconstituent of essential biomolecules such as nucleic acids, phospholipids, and phosphosugars,and as a major contributor to almost all metabolic reactions including photosynthesis,respiration, and energy delivery. it is one of the most needed nutrients for plant growth anddevelopment. despite high levels of...

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...

Nowadays, the use of antagonistic bacteria is widely applied in agriculture and used as biological control. A previous study which yet to be identified based on physiological biochemical characterizations discovered these organisms present coffee plant litter could control fusarium wilt disease. Therefore, this a follow-up analysis that aims identify with ability The investigation techniques we...
