Genotoxicity of Brosimum gaudichaudii measured by the Salmonella/microsome assay and chromosomal aberrations in CHO cells
(Elsevier B.V., 2002-07-01)
The root bark of Brosimum gaudichaudii Trecul (Moraceae) is popularly used for treatment of vitiligo. In the present study the mutagenic activity of the aqueous and methanolic extract as well as of the n-butanolic fraction ...
Classical and molecular cytogenetic analysis in head and neck squamous cell carcinomas
(Sociedade Brasileira de Genética, 2003-01-01)
Head and neck carcinomas represent the sixth most frequent type of cancer in the world, and 90% are derived from squamous cells (HNSCC). In this study of 15 HNSCC cases, extensive aneuploidy was detected by G banding in ...

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 ...

Comparative effects of acute and subacute lycopene administration on chromosomal aberrations induced by cisplatin in male rats
(Elsevier B.V., 2006-08-01)
Lycopene is a natural carotenoid, free radical scavenger, and presents protective effects by inhibiting oxidative DNA damage. The objective of the current study was to investigate the cytogenetic effects of a single acute ...

Response to comment on "Re: Cottliar et al.: High frequencies of telomeric associations, chromosome aberrations and sister chromatid exchanges in ulcerative colitis"
(Nature Publishing Group, 2001-05)
Response to Drs. Marepally and Tobi. To the editor: We read with interest the letter by Marepally and Tobi and welcome the opportunity to discuss some points. The pathways that contribute to telomericassociation (TA) ...
