Mutagenic and carcinogenic potential of a textile azo dye processing plant effluent that impacts a drinking water source
(Elsevier B.V., 2007-01-10)
Recently a textile azo dye processing plant effluent was identified as one of the sources of mutagenic activity detected in the Cristais River, a drinking water source in Brazil [G.A. Umbuzeiro, D.A. Roubicek, C.M. Rech, ...

Characterization of a PDLC mixed with crystal violet dye
(2008)
Accumulated evidence indicated that hepatitis B virus genotype G (HBV/G) is present exclusively in coinfection with other HBV genotypes. In Mexico, HBV/G from 6 men who had sex with men were coinfected with HBV/H. ...
Potencial toxicogenômico do contaminante ambiental 2-fenilbenzotriazol-9 não clorado (non-Cl PBTA-9) in vivo
(Universidade Estadual Paulista (Unesp), 2020-03-02)
O setor industrial, em constante expansão, gera, diariamente, resíduos com elevado potencial tóxico ao ambiente. Nesse contexto, a indústria têxtil apresenta grande impacto poluidor para a hidrosfera, devido aos compostos ...
Mutagenicity of a novel 2-phenylbenzotriazole (non-chlorinated 2-phenylbenzotriazole-9) in mice
(2021-10-01)
Dinitrophenylazo dyes can form 2-phenylbenzotriazoles (PBTAs) in the textile dyeing process upon the addition of chemical reducing agents. Some dinitrophenylazo dyes, as well as their respective reduced (non-chlorinated) ...
Dependence on the atmosphere of preparation of the luminescence of spark processed porous GaAs
(2012-12-17)
We report on the preparation of photoluminescent porous GaAs by the application of high voltage
spark discharges in atmospheres of pure oxygen, pure nitrogen, and in mixed N2:O2 ratios of 4:1
and 1:4. The spark-processed ...

Proanthocyanidins polymeric tannin from Stryphnodendron adstringens are active against Candida albicans biofilms
(BioMed Central, 2015)
Abstract
Background
Biofilm formation is important in Candida albicans pathogenesis and constitutes a mechanism of antifungal resistance. Thus, we evaluated the effect of ...
Tombaugh 2: the first open cluster with a significant abundance spread or embedded in a cold stellar stream?
(2008)
We present new high-resolution spectroscopy from which we derive abundances and radial velocities for stars in the field of the open cluster Tombaugh 2 (To2), which has been suggested to be one of a group of clusters ...
