When a fish or a reptile changes color, it is because of the movement of tiny pigment granules in specialized skin cells called melanophores. These cells have hundreds of membrane-bound pigment granules, or melanosomes, which can be aggregated at the center of the cell or dispersed throughout the cytoplasm. When the melanosomes are aggregated the animal appears lighter, and as they disperse the...

22 In this paper we present a novel image-based approach for characterizing and classifying blue and green pigments as used in paintings based on their optical properties. Our aim is to develop a non-destructive method that can characterize and classify watercolours through a statistical approach which recognizes both the probabilistic nature of the optical watercolour information and the form ...

Phthalocyanine pigments have many problems in waterborne coating applications because of their low polarity, poor dispersion water, and easy agglomeration properties. In order to solve these problems, the phthalocyanine were encapsulated with a copolymer methyl methacrylate (MMA) butyl acrylate (BA) by mini-emulsion polymerization method. The are effectively dispersed water good compatibility r...

The 1.70 Å-resolution X-ray crystal structure of the green pigment occasionally present in nitrite-cured meat reveals a regiospecific nitration of the heme at the 2-vinyl position; the regiospecificity is favored on steric grounds, and results in movement of the 2-nitrovinyl moiety into the plane of the 24-atom heme macrocycle.

Serratia marcescens is an emerging nosocomial pathogen associated with urinary and respiratory tract infections. In this study, we determined the genome of a green pigment-producing clinical strain, U36365, isolated from a hospital in Southern India. De novo assembly of PacBio long-read sequencing indicates that the U36365 genome consists of a chromosome of 5.12 Mbps and no plasmids.

in the form of methaemoglobin, but was apparently accounted for as carboxyhaemoglobin after the addition of carbon monoxide and dithionite. 4. The green pigment is distinct from choleglobin, and its formation is not prevented by carbon monoxide, showing that oxyhaemoglobin is not an intermediate in the reaction. We wish to thank Mr B. A. Collett for technical assistance during a part of the work.
