Characterization of myeloid or lymphoid acute leukemia by a chemiluminescence assay: Comparison with immunocytochemistry using an antimyeloperoxidase antibody
(Acta Haematologica, 1993-01-01) [Artigo]
A simple and sensitive chemiluminescence assay for the demonstration of the activity of intracellular myeloperoxidase (MPO) is described, which is useful for the distinction between myeloid and lymphoid commitment in blasts ...
In vitro antimicrobial efficiency of a mouthwash containing triclosan/gantrez and sodium bicarbonate
(Brazilian Oral Research, 2007-12-31) [Artigo]
Several antiseptic substances have been used as adjuncts to routine mechanical procedures of oral hygiene, based on their antimicrobial effects. The objective of this study was to assess in vitro the antimicrobial efficiency ...
Antitumor and antimycobacterial activities of cyclopalladated complexes: X-ray structure of [Pd(C-2,N-dmba)(Br)(tu)] (dmba = N,N-dimethylbenzylamine, tu = thiourea)
(European Journal of Medicinal Chemistry, 2009-11-01) [Artigo]
The reactions between [Pd(C-2,N-dmba)(mu-X)](2) (dmba = N,N-dimethylbenzylamine: X = Cl, Br) and thiourea (tu) in the 1:2 molar ratio at room temperature resulted in the mononuclear compounds [Pd(C-2,N-dmba)(Cl)(tu)] (1) ...

(Revista do Instituto de Medicina Tropical de São Paulo, 2007-02-01) [Artigo]
Cryptococcus neoformans, pertencente à classe dos basidiomicetos, é um importante patógeno, principalmente em pacientes imunocomprometidos. Neste estudo, 47 isolados clínicos de C. neoformans de várias regiões do Estado ...
Isolation of ergosterol peroxide and its reversion to ergosterol in the pathogenic fungus Sporothrix schenckii
(Mycopathologia, 1997-12-01) [Artigo]
Ergosterol peroxide, a presumed product of the H2O2-dependent enzymatic oxidation of ergosterol, has been isolated from yeast from yeast forms of the pathogenic fungus Sporothrix schenckii. The substance, which may have a ...
Taurine bromamine: A potent oxidant of tryptophan residues in albumin
(Archives of Biochemistry and Biophysics, 2011-03-15) [Artigo]
Taurine is the most abundant free amino acid in leukocytes and can react with HOBr to produce taurine bromamine (Tau-NHBr). The aim of this study was to assess the ability of Tau-NHBr to oxidize tryptophan, either free or ...
Immune Response Against Sporothrix schenckii in TLR-4-Deficient Mice
(Mycopathologia, 2012-07-01) [Artigo]
For many fungal diseases, macrophages are the major cell population implicated in host protection, primarily by their ability to eliminate the invading fungal pathogen through phagocytosis. In sporotrichosis, this remains ...

Altered Ex Vivo Expression of Caspase 8, Caspase 9, and Bcl-2 Is Associated with T-Cell Hyporeactivity in Patients with Paracoccidioidomycosis
(Clinical and Vaccine Immunology, 2009-06-01) [Artigo]
To better understand the T-cell hyporesponsiveness of patients with paracoccidioidomycosis, we tested the hypothesis that the T cells were committed to apoptosis. We show here that T cells of patients with paracoccidioidomycosis ...
