Authors: M.S. Reynoso, C.M. Alvarez, L.L. De la Cruz, J.F.G. Landeros, J.J.G. S�¡nchez, A.R.A. Villalobos
In order to encourage corn production, several herbicides such as nicosulfuron and topramezone are used. Though they offer great advantages, they may affect crop productivity and may even induce DNA damage. This study evaluated genotoxic activity at two nicosulfuron concentrations (40,000 and 80, 000 ppm) and at four topramezone concentrations (1480, 148,.. Read More»

Anthocyanins-loaded Eudragit�® L100 nanoparticles: in vitro cytotoxic and genotoxic analysis
Authors: TB de Queiroz, D Dupeyr�³n, JCT Carvalho, IOM Gaiv�£o, and EL Maistro
Anthocyanins are flavonoids compounds that have a great therapeutic potential acting as antioxidants, anti-inflammatory and anti-carcinogenic agents. They are consumed through food, pharmaceutical and cosmetics industries as a natural alternative to synthetic dyes. However, anthocyanins are unstable depending on pH, temperatur.. Read More»

Cellular responses induced in vitro by pestheic acid, a fungal metabolite, in a gastric adenocarcinoma cell line (PG100)
Authors: J.M.C. Sousa, L.A. Matos, D.F.A. Alc�¢ntara, H.F. Ribeiro, L.S. Santos, M.N. Oliveira, L.C. Brito-Junior, A.S. Khayat, A.C. Guimar�£es, L.A. Cunha, R.R. Burbano and M.O. Bahia
There is a constant search for new cancer treatments that are less aggressive and economically affordable. In this context, natural products extracted from plants, fungi, and microorganisms are of great interest. Pestheic acid, or dihidromaldoxin, is a chlorinated diphenylic ether extracted from the phytopathogenic fungus Pestalotiopsis guepinii (Amphisph.. Read More»

Pre-treatment with glutamine reduces genetic damage due to cancer treatment with cisplatin
Authors: R.J. Oliveira, E.S. Sassaki, A.C.D. Monreal, M.T.F.D. Monreal,J.R. Pesarini, M.O. Mauro, R. Matuo, A.F. Silva, N.N. Zobiole,J.M. Siqueira, L.R. Ribeiro, M.S. Mantovani
Cisplatin is an effective antineoplastic drug. However, it provokes considerable collateral effects, including genotoxic and clastogenic activity. It has been reported that a diet rich in glutamine can help inhibit such collateral effects. We evaluated this activity in 40 Swiss mice, distributed into eight experimental groups:.. Read More»

Induced mitotic homologous recombination by the babesicide imidocarb dipropionate in Aspergillus nidulans diploid cells
Authors: P.A.S.R. Santos, J.R. Sant�Anna, C.C.S. Franco, L.J. Rosada, G.N.M. Esquissato and M.A.A. Castro-Prado
Imidocarb dipropionate (IMD) is a chemotherapeutic agent prescribed for the treatment and control of babesiosis; it is known to be a nucleic acid synthesis inhibitor. Although it is an effective babesicide, there are reports of persistent IMD residues retained at high levels in edible tissues of cattle, swine and sheep, raising concerns about potential ef..

Assessing the genotoxicities of sparteine and compounds isolated from Lupinus mexicanus and L. montanus seeds by using comet assay
Authors: M.R. Silva, C.M. Alvarez, P.M. GarcÃ?Âa and M.A. Ruiz
The genus Lupinus is widely distributed. Its seeds are used for animal and human food, and Lupinus possesses pharmacological potential because of its high content of quinolizidine alkaloids and flavonoids; however, there is little available information about its genotoxicity. We used the comet assay and staminal nuclei of Tradescantia (clone 4430) to eval.. Read More»

The radiotracer 99mTc-MIBI is not genotoxic for human peripheral blood lymphocytes at diagnostic radioactive dose
Authors: S.J. Hosseinimehr1, A. Ahmadi1, D. Beiki2, A. Mahmoudzadeh3, M. Babaei4 and E. Habibi1
The radiotracer technetium-99m methoxyisobutyl isonitrile (99mTc-MIBI) has been widely used for myocardial blood flow imaging. We investigated the genotoxicity of 99mTc-MIBI in cultured human lymphocytes at the same concentration used in patients. Radioactivity doses were determined in whole blood at 5 min post-injection of 20 mCi 99mTc-MIBI in patients. .. Read More»

Protective effects of �²-carotene against the genotoxicity of doxorubicin in somatic cells of Drosophila melanogaster
Authors: C.D. Dias, B.C. Ara�ºjo, E.S. Dutra and J.C. Nepomuceno
β-carotene (BC), pro-vitamin A, is an efficient antioxidant, effective in the neutralization of oxygen reactive species, which cause serious damage to DNA. Various studies have been conducted on the effectiveness of BC for chemoprevention of cancer and heart disease. Doxorubicin is a chemotherapeutic agent used for cancer.. Read More»

Aspergillus nidulans as a biological system to detect the genotoxic effects of mercury fumes on eukaryotes
Authors: G.D. Sousa, T.D. Zucchi, F.D. Zucchi, R.G. Miller1, R.M.A. Anjos,P. Poli and T.M.A.D. Zucchi
Mercury (Hg) pollution is one of the most serious environmental problems. Due to public concern prompted by the symptoms displayed by people who consumed contaminated fish in Minamata, Japan in 1956, Hg pollution has since been kept under constant surveillance. However, despite considerable accumulation of knowledge on the nox.. Read More»

N-nitrosodiethylamine genotoxicity evaluation: a cytochrome P450 induction study in rat hepatocytes
Authors: C.A.F. Aiub, G. Gadermaier, I.O. Silva, I. Felzenszwalb, L.F.R. Pinto, F. Ferreira and P. Eckl
In rats, N-nitrosodiethylamine (NDEA) induces tumors mainly in the liver. This could be because various enzymes are responsible for the metabolic activation of NDEA, besides the hepatic NDEA metabolizing enzyme, CYP2E1. We examined NDEA genotoxicity and cytotoxicity in primary cultures of female rat hepatocytes; we also looked.. Read More»
