Avaliação do estresse oxidativo no sangue de consumidores habituais de suco de laranja
(Revista de Ciências Farmacêuticas Básica e Aplicada, 2011-11-14) [Artigo]
Two biomarkers of oxidative stress were evaluated in healthy volunteers treated with daily doses of orange juice that is well known source of vitamin C and citric flavanones, which have been associated with antioxidant, ...
Response of macrophage Toll-like receptor 4 to a Sporothrix schenckii lipid extract during experimental sporotrichosis
(Immunology, 2009-10-01) [Artigo]
P>Toll-like receptors have been implicated in the recognition of various pathogens, including bacteria, viruses, protozoa and fungi. However, no information is available about Toll-like receptor 4 (TLR4) participation in ...
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 ...
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 ...
First data in the effect of Araraquara soybean yogurt on Buenos Aires tumor-cell lines
(Annual Review of Biomedical Sciences, 2005) [Artigo]
Effect of post-polymerization heat treatments on the cytotoxicity of two denture base acrylic resins
(Journal of Applied Oral Science, 2006-08-31) [Artigo]
Introduction: Most denture base acrylic resins have polymethylmethacrylate in their composition. Several authors have discussed the polymerization process involved in converting monomer into polymer because adequate ...
Host organism defense by a peptide-polysaccharide extracted from the fungus Sporothrix schenckii
(Mycopathologia, 1998-01-01) [Artigo]
A peptide-polysaccharide, a peptide-rhamnomannan, was isolated from the pathogenic yeast form of the fungus Sporothrix schenckii. This substance, which may play a role in fungal virulence, was tested in an animal model of ...
Antitumor and immunomodulatory effects of the naphthoquinone 5-methoxy-3,4-dehydroxanthomegnin
(Revista Brasileira de Farmacognosia, 2011-12-01) [Artigo]
Large number of quinones has been associated with antitumor, antibacterial, antimalarial and antifungal activities. In this work we describe the effect of the naphthoquinone, 5-methoxy-3,4-dehydroxanthomegnin, on murine ...
Inhibition of Nitric Oxide and Tumour Necrosis Factor-alpha Production in Peritoneal Macrophages by Aspergillus nidulans Melanin
(Biological & Pharmaceutical Bulletin, 2013-12-01) [Artigo]
The naturally occurring pigment, melanin is found in organisms of all phylogenetic kingdoms, including fungi, and exhibits a wide range of biological activities. Our objective was to investigate the effects of melanin ...
Anti-inflammatory activity of Alchornea triplinervia ethyl acetate fraction: Inhibition of H2O2, NO and TNF-alpha
(Pharmaceutical Biology, 2010-12-01) [Artigo]
Context: Alchornea triplinervia (Spreng.) Mull. Arg. (Euphorbiaceae) is a tree widespread in many Brazilian states. This plant naturally occurs in different ecosystems including tropical Atlantic forest, Amazon rain forest, ...
