Genetic damage in Mexican and South American sweet corn varieties due to the use of herbicides (Nicosulfuron and Topramezone)

Authors: M.S. Reynoso, C.M. Alvarez, L.L. De la Cruz, J.F.G. Landeros, J.J.G. Sánchez, 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»

Antigenotoxic and antimutagenic effects of Schinus terebinthifolius Raddi in Allium cepa and Swiss mice: A comparative study

Authors: L.E.S. Fedel-Miyasato, A.S.N. Formagio, S.A. Auharek, C.A.L. Kassuya, S.D. Navarro, A.L. Cunha-Laura, A.C.D. Monreal, M.C. Vieira and R.J. Oliveira

It is estimated that 60% of anticancer drugs are derived directly or indirectly from medicinal plants. Schinus terebinthifolius Raddi (Anacardiaceae) is traditionally used in Brazilian medicine to treat inflammation, ulcers, and tumors. Because of the need to identify new antimutagenic agents and to determine their mechanism o.. Read More»

Lack of genotoxicity in Astyanax bimaculatus and Oreochromis niloticus of 17α-methyltestosterone used in fish hatcheries to produce male monosex populations

Authors: C.L.G. Rivero-Wendt1, A.L. Miranda-Vilela1, M.F.N. Ferreira1, F.S. Amorim2, V.A.G. da Silva2, H. Louvandini3 and C.K. Grisolia1

17α-Methyltestosterone (MT) is widely used in fish hatcheries of many countries to produce male monosex populations. Its genotoxic risk to fish species is not well known and studies in other in vivo models are still inconclusive. MT was tested for genotoxicity in the fish species Oreochromis niloticus (tilapia), a target species, and Astyanax bimacu.. Read More»

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. García 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»

Castor bean (Ricinus communis L.) as a potential environmental bioindicator

Authors: M.G. Mendes, C.D. Santos Junior, A.C.C. Dias and A.M. Bonetti

Biomonitoring of air quality using living organisms is a very interesting approach to environmental impact assessment. Organisms with a vast distribution, such as plants, are widely used for these purposes. The castor bean (Ricinus communis L.) is an oleaginous plant that can potentially be used as a bioindicator plant owing to its rapid growth and large .. Read More»

Hyperproliferative action of bovine papillomavirus: genetic and histopathological aspects

Authors: R.P. Araldi, T.C. Melo, A.C. Neves, D.D. Spadacci-Morena, R.F. Magnelli, D.G. Modolo, P.L. de-Sá-Júnior, J. Mazucchelli-de-Souza, R.F. Carvalho, W. Beçak and R.C. Stocco

The bovine papillomavirus (BPV) causes papillomas that regress spontaneously, but can also progress to malignancy. This study evaluated the role of BPV in oncogenesis. Twenty-four samples from uninfected calves and the papillomas of BPV infected cattle were subjected to molecular diagnosis, as well as histopathological and immunohistochemical analyses. Th..
