(Revista Brasileira De Parasitologia Veterinaria, 2014-04-01) [Artigo]
The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode ...
Prostaglandin E-2 production by high and low virulent strains of Paracoccidioides brasiliensis
(Mycopathologia, 2007-03-01) [Artigo]
The production of prostaglandins (PGs) during fungal infections could be an important suppressor factor of host immune response. Host cells are one source of prostaglandin E-2 (PGE(2)); however another potential source of ...
Compounds used to produce cloned animals are genotoxic and mutagenic in mammalian assays in vitro and in vivo
(Brazilian Journal of Medical and Biological Research, 2014-04-01) [Artigo]
The compounds 6-dimethylaminopurine and cycloheximide promote the successful production of cloned mammals and have been used in the development of embryos produced by somatic cell nuclear transfer. This study investigated ...
Comparison between human and armadillo Paracoccidioides brasiliensis isolates by random amplified polymorphic DNA analysis
(Mycopathologia, 1998-01-01) [Artigo]
Sixty-three Paracoccidioides brasiliensis isolates obtained from three nine-banded armadillos (Dasypus novem-cinctus), one Amazonian armadillo's and 19 clinical isolates were compared by random amplified polymorphic DNA ...

Lemongrass (Cymbopogon citratus Stapf) essential oil has been used worldwide because of its ethnobotanical and medicinal usefulness. Regarding its medicinal usefulness, the present study evaluated the beneficial effects ...
Histological and immunological reaction of cattle skin to first-instar larvae of Dermatobia hominis
(Medical and Veterinary Entomology, 1996-10-01) [Artigo]
Six cattle that had earlier exposure to Dermatobia hominis were infested experimentally with first-instar larvae of the parasite. Skin biopsies taken at intervals were studied in wax and in plastic sections. The ...
Chemically induced immunotoxicity in a medium-term multiorgan bioassay for carcinogenesis with Wistar rats
(Toxicology and Applied Pharmacology, 2004-01-15) [Artigo]
A variety of chemicals can adversely affect the immune system and influence tumor development. The modifying potential of chemical carcinogens on the lymphoid organs and cytokine production of rats submitted to a medium-term ...

(Toxicology, 2006-07-05) [Artigo]
Diuron (3-(3,4-dichlorophenyl)-1,1-dimethylurea) is a substituted urea herbicide widely used on agricultural crops such as soy, cotton and sugar cane. In a previous long-term study this herbicide exerted carcinogenic ...
Antigenic similarities to Paracoccidioides brasiliensis in thermo-dependent dimorphic fungi isolated from soil in Botucatu, SP, Brazil
(Mycopathologia, 1997-01-01) [Artigo]
We compared the antigenic characteristics of two thermo-dependent dimorphic fungi isolated from soil in Botucatu, an endemic area of paracoccidioidomycosis (PCM) and Paracoccidioides brasiliensis. The soil isolates grew ...
