Inside-out vs. standard vein graft to repair a sensory nerve in rats
(Anatomical Record, 1999-11-09) [Artigo]
Nerve regeneration in a sensory nerve was obtained by the application of different techniques: inside-out vein graft (IOVG group) and standard vein graft (SVG group). These techniques provide a good microenvironment for ...
Effect of chronic food restriction on the mechanical performance of normal and hypertrophied myocardium
(FASEB Journal, 2000-03-15) [Resumo]
Detection of Listeria sp in meat and meat products using TECRA Listeria visual immunoassay and biocontrol visual immunoprecipitate assay for Listeria immunoassays and a cultural procedure
(Journal of Rapid Methods and Automation In Microbiology, 2005-09-01) [Artigo]
The routine methods for detecting Listeria sp. in foods are time consuming and involve using selective enrichments and plating on agars. In this study, the presence of Listeria sp. in 120 meat and meat product samples was ...
Determination of a point sufficiently close to the asymptote in nonlinear growth functions
(Scientia Agricola, 2011-02-01) [Artigo]
Em funções de crescimento que apresentam uma assíntota horizontal superior à curva, frequentemente surge a questão sobre quando se pode considerar o crescimento como praticamente constante, isto é, quando a curva está ...
Profile of thyroid hormones in breast cancer patients
(Brazilian Journal of Medical and Biological Research, 2005-05-01) [Artigo]
Estrogen involvement in breast cancer has been established; however, the association between breast cancer and thyroid diseases is controversial. Estrogen-like effects of thyroid hormone on breast cancer cell growth in ...
Effects of uracil calculi on cell growth and apoptosis in the BBN-initiated Wistar rat urinary bladder mucosa
(Teratogenesis Carcinogenesis and Mutagenesis, 1999-01-01) [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- ...
Influence of estradiol and triiodothyronine on breast cancer cell lines proliferation and expression of estrogen and thyroid hormone receptors
(Arquivos Brasileiros de Endocrinologia & Metabologia, 2009-10-01) [Artigo]
OBJETIVO: Para compreender melhor a ação da triiodotironina (T3) agonista de estrógeno (E2), foram comparados os efeitos destes hormônios em células de câncer de mama MDA-MB-231 ER negativas com um clone de MDA-MB-231, ...
Accuracy of six minute walk test, stair test and spirometry using maximal oxygen uptake as gold standard
(Acta Cirúrgica Brasileira, 2010-04-01) [Artigo]
OBJETIVO: Determinar a acurácia das variáveis: tempo de escada (tTE), potência de escada (PTE), teste de caminhada (TC6) e volume expiratório forçado (VEF1) utilizando o consumo máximo de oxigênio (VO2máx) como padrão-ouro. ...
Structural evaluation of the effects of chronic ethanol ingestion on the testis of Calomys callosus
(Tissue & Cell, 2009-06-01) [Artigo]
Chronic exposure to ethanol may results in pathophysiologic changes in cellular function. The present work was designed to investigate the morphology of testis submitted to experimental ethanol ingestion. Experimental ...
Low-power laser irradiation improves histomorphometrical parameters and bone matrix organization during tibia wound healing in rats
(Journal of Photochemistry and Photobiology B: Biology, 2003-05-01) [Artigo]
The influence of daily energy doses of 0.03, 0.3 and 0.9 J of He-Ne laser irradiation on the repair of surgically produced tibia damage was investigated in Wistar rats. Laser treatment was initiated 24 h after the trauma ...
