(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 ...
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 ...
Modifying Effects of Lemongrass Essential Oil on Specific Tissue Response to the Carcinogen N-Methyl-N-Nitrosurea in Female BALB/c Mice
(Journal of Medicinal Food, 2012-02-01) [Artigo]
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 ...
Effects of uracil calculi on cell growth and apoptosis in the BBN- initiated Wistar rat urinary bladder mucosa
(Teratogenesis Carcinogenesis and Mutagenesis, 1999-07-28) [Artigo]
The different potential of initiated and non-initiated urinary bladder mucosa (UBM) to develop neoplasia was quantitatively evaluated in the male Wistar rat. Initiation of carcinogenesis was accomplished with N-butyl-N-(4- ...
Antitumor properties of Ganoderma lucidum polysaccharides and terpenoids
(Annual Review of Biomedical Sciences, 2011-12-01) [Artigo]
Ganoderma lucidum is an edible medicinal mushroom with immunomodulatory and antitumor properties, which are mainly attributed to polysaccharides and triterpenes that can be isolated from mycelia, fruiting bodies and spores. ...
Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-03-06) [Artigo]
Aqueous extracts of the sporophores of eight mushroom species were assessed for their ability to prevent H2O2-induced oxidative damage to cellular DNA using the single-cell gel electrophoresis (Comet) assay. The highest ...
