as evidence of autoimmune phenomena. The experimental production of positive antiglobulin tests by drugs and chemical agents, however, has suggested that nonimmunologic mechanisms may also be responsible for protein coating of erythrocytes.2’3 During attempts to produce tumors of the reticuloendothelial system in rats by injection of trypan blue, an anemia, chacacterized by increased ervthrocyt...

UNLABELLED The blue wavelengths within the visible light spectrum are intrinisically antimicrobial and can photodynamically inactivate the cells of a wide spectrum of bacteria (Gram positive and negative) and fungi. Furthermore, blue light is equally effective against both drug-sensitive and -resistant members of target species and is less detrimental to mammalian cells than is UV radiation. Bl...

We present a new direct Poisson disk sampling for surface meshes. Our objective is to sample triangular meshes, while satisfying good blue noise properties, but also preserving features. Our method combines a feature detection technique based on vertex curvature, and geodesic-based dart throwing. Our method is fast, automatic, and experimental results prove that our method is well-suited to CAD...

A 71-year-old woman with the blue rubber bleb naevus syndrome experienced 4 episodes of self-limiting unilateral exophthalmos. Is is suggested that a vascular malformation in the orbit is responsible for this phenomenon. A biopsy sample was taken of one of the cutaneous lesions and studied by light and transmission electron microscopy. The histological appearances are discussed in relation to p...

Thirteen-week subchronic toxicity studies of direct blue 6, direct black 38, and direct brown 95 dyes were conducted by administering the test chemicals in feed to Fischer 344 rats and B6C3F1 mice. Groups of 10 rats and 10 mice of each sex were administered one of the three dyes at one of five concentrations for 13 weeks and then necropsied, beginning the second day after the end of the dosing ...

the api 20e technique for identification of e.coli was evaluated and the results compared with those obtained by the conventional biochemical tests recommended in report 71. the results obtained showed very close correlation between the two methods. a total of 196 (81.6%) out of 240 isolates were identified as e.coli by api. system, while the conventional method identified only 194 (80.8%). the...

Infection by endosymbiotic bacteria is an underappreciated threat to endangered arthropods with serious implications for captive management programs. We examined the nature of Wolbachia infection in the North American endangered Karner blue butterfly, Lycaeides melissa samuelis, as a case study. Screening for Wolbachia across the range of the species confirmed widespread infection in the wester...

The photodegradation of Direct Blue 258, a member of the group of azo dyes which are commonly used in the various branches of the industry, was studied. The photostability of this dye was not previously surveyed. Photocatalytic degradation method was evaluated. The both light source include solar simulated (UV 400 W lamp) and sun light (E= 400 W/m2) and titanium dioxide nanoparticles were used ...
