DNA methylation patterns in bladder cancer and washing cell sediments: a perspective for tumor recurrence detection
(BMC Cancer, 2008-08-14) [Artigo]
Background: Epigenetic alterations are a hallmark of human cancer. In this study, we aimed to investigate whether aberrant DNA methylation of cancer-associated genes is related to urinary bladder cancer recurrence.Methods: ...
The relationship between the degree of thrombocytopenia and infection with Ehrlichia canis in an endemic area
(Veterinary Research, 2004-01-01) [Artigo]
Ehrlichia canis is the causative agent of canine monocytic ehrlichiosis. In order to evaluate platelet counts as a screening test for E. canis in an endemic area, 217 whole blood samples from dogs were divided into three ...
Evaluation of estrogen receptor alpha and beta and progesterone receptor expression and correlation with clinicopathologic factors and proliferative marker Ki-67 in breast cancers
(Human Pathology, 2008-05-01) [Artigo]
To elucidate the molecular profile of hormonal steroid receptor status, we analyzed ER-alpha, ER-beta, and PGR mRNA and protein expression in 80 breast carcinomas using reverse transcriptase polymerase chain reaction ...
Parasitic infection of the appendix as a cause of acute appendicitis
(Parasitology Research, 2007-12-01) [Artigo]
The association between parasitic infection of the appendix and acute appendicitis has been widely investigated. The aim of this retrospective study was to evaluate the prevalence of parasitic infection of the appendix in ...
Appendiceal taeniasis presenting like acute appendicitis
(Parasitology Research, 2005-09-01) [Artigo]
A case of parasitic appendicitis caused by Taenia sp. in a 28-year-old woman from Brazil is reported. Histopathological data and a description of the helminthe found in the appendix lumen are presented.
Polysaccharide fraction of Agaricus brasiliensis avoids tumor-induced IL-10 production and changes the microenvironment of subcutaneous Ehrlich adenocarcinoma
(Cellular Immunology, 2009-01-01) [Artigo]
Subcutaneous Ehrlich tumor-bearing mice were treated with in situ inoculation of a P-glucan-rich extract of Agaricus brasiliensis (ATF), which reduced tumor growth. Histopathological analysis showed that the tumor masses ...
Lymphoproliferative response and T lymphocyte subsets in a medium-term multi-organ bioassay for carcinogenesis in Wistar rats
(Cancer Letters, 2000-06-30) [Artigo]
The lymphoproliferative response and T lymphocyte subsets were evaluated at different stages of carcinogenesis in male Wistar, rats sequentially initiated with N-diethylnitrosamine (DEN), N-butyl-N-4(hydroxybutyl)nitrosamine ...
Antitumoural effect of an L-amino acid oxidase isolated from Bothrops jararaca snake venom
(Basic & Clinical Pharmacology & Toxicology, 2008-06-01) [Artigo]
An L-amino acid oxidase (BjarLAAO-I) from Bothrops jararaca snake venom was highly purified using a stepwise sequential chromatography on Sephadex G-75, Benzamidine Sepharose and Phenyl Sepharose. Purified BjarLAAO-I showed ...
Occurrence of coagulase-positive Staphylococcus in various food products commercialized in Botucatu, SP, Brazil and detection of toxins from food and isolated strains
(Food Control, 2007-06-01) [Artigo]
The aim of this work was to assess the microbiological quality of commercialized desserts, sandwiches and finger food in Botucatu, SP, for human consumption. A total of 172 food samples were analyzed for fecal coliforms ...
Chemopreventive property of dietary ginger in rat urinary bladder chemical carcinogenesis
(World Journal of Urology, 2006-11-01) [Artigo]
The modifying potential of ginger on the development of preneoplasia and tumors in the male Wistar rat urinary bladder was investigated in a 36-week-long initiation-promotion assay for chemical carcinogenesis. Groups G1 ...
