During the years 2007 and 2008, samples of winter jasmine (Jasminum nudiflorum) with symptoms of galls on shoots were collected from Shiraz, Fars province, Iran. Gram and oxidase negative, aerobic bacterium that produced fluorescent pigment on Kingۥs B medium was isolated from galls of infected trees. All isolates produced a hypersensitive reaction in tobacco. They were negative in arginine dih...

purpose: to report a case of butterfly-shaped macular dystrophy. patient and findings: a 34-year-old woman presented with metamorphopsia in both eyes from 2 years ago. visual acuity was 9/10 in right eye and 10/10 in left eye. there was no pathologic finding on slit lamp biomicroscopy and funduscopy other than mild macular retinal pigment epithelium mottling. visual fields and electroretinogram...

background and objectives: in marine actinomycetes, carotenoid production occurs in constitutive, light-dependent or cryptic manner. the present work deals with the fermentative production of carotenoids from marine actinomycetes. materials and methods: marine actinomycetes namely streptomyces strain aqbmm35 was isolated from the marine sponge mycale mytilorum collected from south west coast of...

Sixty-four eyes of 57 elderly patients with pigment epithelial detachments (PEDs) were studied with the aim of describing their morphological features and identifying prognostic factors. They were classified into four groups according to the following characteristics: early fluorescence, late fluorescence, shallow detachment with limited fluorescence ('drusen type'), irregular fluorescence. The...

Abstract Fluorescence-based materials that are affordable and easy to use for commercial anti-counterfeiting applications in high demand. While exploring new fluorescent pigments, a pyrene-naphthalimide Schiff base, 5-hydroxy-2-((pyren-1-ylmethylene)amino)-1 H -benzo[ de ]isoquinoline-1,3(2 )-dione (NHPY) with yellow fluorescence under UV light was synthesized. An eco-friendly flexographic ink ...

Fluorescent coatings have attracted attention due to their bright colors. However, they fewer outdoor applications low stability, especially the poor weather resistance of fluorescent pigments. In order improve and maintain excellent appearance, this study used polymer binders coat a light shielding agent nano TiO2 on surface pigment extend durability. Three organic binders, polyester varnish, ...
