Journal ArticleDOI
Cytogenetic damage related to low levels of methyl mercury contamination in the Brazilian Amazon
M. Amorim,Donna Mergler,Marcelo de Oliveira Bahia,H. Dubeau,Daniela Miranda,Jean Lebel,Rommel Rodríguez Burbano,Marc Lucotte +7 more
TL;DR: The results strongly suggest that MeHg is both a spindle poison and a clastogen, and should be taken into account in the preliminary evaluation of the risks to populations exposed in vivo.
Journal ArticleDOI
Cytotoxicity and genotoxicity of low doses of mercury chloride and methylmercury chloride on human lymphocytes in vitro
Liz Carmem Silva-Pereira,Plínio Cerqueira dos Santos Cardoso,Plínio Cerqueira dos Santos Cardoso,Daniel Silva Leite,Marcelo de Oliveira Bahia,Marcelo de Oliveira Bahia,Wanderley Rodrigues Bastos,Marília de Arruda Cardoso Smith,Rommel Rodríguez Burbano,Rommel Rodríguez Burbano +9 more
TL;DR: Data showed that low concentrations of CH3HgCl might be cytotoxic/genotoxic, and effects may indicate early cellular changes with possible biological consequences and should be considered in the preliminary evaluation of the risks of populations exposed in vivo to low doses of mercury.
Journal ArticleDOI
Genotoxic effects of aluminum, iron and manganese in human cells and experimental systems: a review of the literature.
P.D.L. Lima,Marne Carvalho de Vasconcellos,Raquel Carvalho Montenegro,Marcelo de Oliveira Bahia,Edmar Tavares da Costa,Lusânia Maria Greggi Antunes,Rommel Rodríguez Burbano +6 more
TL;DR: This study is a review of the data found concerning the genotoxic potential of three metals: aluminum (Al), iron (Fe) and manganese (Mn), with emphasis on their action on human cells.
Journal Article
The anticancer homeopathic composite "Canova Method" is not genotoxic for human lymphocytes in vitro.
Igor Chamon Assumpção Seligmann,P.D.L. Lima,Plínio Cerqueira dos Santos Cardoso,André Salim Khayat,Marcelo de Oliveira Bahia,Dorli de Freitas Buchi,Isabel Rosa Cabral,Rommel Rodríguez Burbano +7 more
TL;DR: Genotoxic effects induced in human lymphocytes treated with this homeopathic medication in vitro were evaluated and there was no cytotoxicity or genotoxicity at the chromosomal level.
Journal ArticleDOI
Genotoxic and cytotoxic effects of manganese chloride in cultured human lymphocytes treated in different phases of cell cycle
P.D.L. Lima,Marne Carvalho de Vasconcellos,Marcelo de Oliveira Bahia,Raquel Carvalho Montenegro,Cláudia Pessoa,Letícia V. Costa-Lotufo,Manoel Odorico de Moraes,Rommel Rodríguez Burbano +7 more
TL;DR: The absence of polyploidy in mitosis, suggests that manganese does not affect the formation of the mitotic spindle with the concentrations tested, and the genotoxicity found in G2 phase and in the comet assay can be related to the short time of treatment in both cases.
