(Instituto de Ciências da Saúde/ Universidade Federal da Bahia, 2010)
Abstract
Papillomavirus is a dermotropic oncogenic DNA virus which induces benign and malignant lesions described in a wide variety
of hosts. Evidences suggest that the virus is species and tissue specific. However several ...
Análisis de los cambios estructurales de células in vitro de Tagetes erecta L. sometidas a biobalística
(2011-11-30)
Tagetes erecta L callus cells ("porte bajo” material) were used as a plant model in order to delivery lcy-β gene (from carotenoids route) by means of biobalistic transformation. The aim was to evaluate the probable ...
Histology of the oocytes of Lutjanus peru (Nichols and Murphy, 1922) (Pisces: Lutjanidae) [Histología de los ovocitos de Lutjanus peru (Nichols y Murphy, 1922) (Pisces: Lutjanidae)]
(2001)
The distinctive characteristics found in each of the development stages of the oocyte in the ovary of Lutjanus peru (Pacific red snapper) are described. The histological technique was used to identify the development stages ...
Chromosomal aberrations induced by 5-azacytidine combined with VP-16 (etoposide) in CHO-K1 and XRS-5 cell lines
(Wiley-Blackwell, 2003-01-01)
A cytogenetic study was carried out with 5-azacytidine (5-azaC) and etoposide (VP-16) in CHO-K1 and XRS-5 (mutant cells deficient for double-strand break rejoining) cell lines to verify the interaction effects of the drugs ...
Correlação entre a citologia aspirativa por agulha fina e a histologia no diagnóstico de tumores mamários de cadelas
(Universidade de São Paulo (USP), Faculdade de Medicina Veterinária e Zootecnia (FMVZ), 2001-01-01)
Foram estudados tumores de mama em cadelas, comparando o seu padrão citológico, obtido através da Citologia Aspirativa por Agulha Fina (CAAF), com os resultados da histopatologia. Num período de um ano, as cadelas trazidas ...

A espermiogênese que ocorre em piracanjuba Brycon orbignyanus pode ser dividida em quatro etapas morfológicas, cujas características principais consistem em reduções dos volumes citoplasmático, nuclear e celular, e compactação ...
LaTBP1: A Leishmania amazonensis DNA-binding protein that associates in vivo with telomeres and GT-rich DNA using a Myb-like domain
(Elsevier B.V., 2007-09-15)
Different species of Leishmania can cause a variety of medically important diseases, whose control and treatment are still health problems. Telomere binding proteins (TBPs) have potential as targets for anti-parasitic ...
Evidence of epigenetic regulation of the tumor suppressor gene cluster flanking RASSF1 in breast cancer cell lines
(Landes Bioscience, 2011-12-01)
Epigenetic mechanisms are frequently deregulated in cancer cells and can lead to the silencing of genes with tumor suppressor activities. The isoform A of the Ras-association domain family member 1 (RASSF1A) gene is one ...
