Large nuclear vacuoles are indicative of abnormal chromatin packaging in human spermatozoa
(Wiley-Blackwell, 2012-02-01)
The aim of this investigation was to determine the presence of abnormal sperm chromatin packaging in spermatozoa with large nuclear vacuoles (LNV) selected via high magnification by analysing the pattern of chromomycin A3 ...
Habitat differences affect the nuclear morphology of the erythrocytes and the hepatic melanin in Leptodactylus fuscus (Anura) in the Brazilian Cerrado savanna
(2021-01-01)
The sensitivity of anuran to the effects of habitat destruction and contamination has led to a preoccupying global decline in their populations. Morphological biomarkers such as micronuclei and other erythrocyte nuclear ...
Caracterização das comunidades de peixes de duas lagoas marginais na bacia do Alto Paranapanema
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Conservação da Fauna - PPGCFauCâmpus São Carlos, 2018-11-30)
Marginal lagoons are considered an integral part of lotic systems, interacting with rivers through the exchange of water, nutrients and living organisms. They play an important role in the maintenance of biodiversity, ...
Cytogenotoxicity biomarkers in fat snook Centropomus parallelus from Cananeia and Sao Vicente estuaries, SP, Brazil
(Soc Brasil Genetica, 2009-01-01)
The aquatic environment receives many contaminants that can induce damages at the molecular, biochemical, cellular and physiological levels. Centropomus parallelus, an important food resource for local populations, is a ...
Mutagenic and genotoxic effects of the Atrazine herbicide in Oreochromis niloticus (Perciformes, Cichlidae) detected by the micronuclei test and the comet assay
(Academic Press Inc. Elsevier B.V., 2008-01-01)
Atrazine is the triazinic herbicide most found in the rural aquatic environments due to its extensive use and its stability in such places. The mutagenicity and the genotoxicity of different concentrations of the Atrazine ...

Hematological changes and cytogenotoxicity in the tilapia Oreochromis niloticus caused by sub-chronic exposures to mercury and selenium
(Springer, 2015-02-01)
Fish bioassays are valuable tools that can be used to elucidate the toxicological potential of numerous substances that are present in the aquatic environment. In this study, we assessed the antagonistic action of selenium ...
Common snook juveniles, Centropomus undecimalis, as biomonitor organisms to evaluate cytogenotoxicity effects of surface estuarine water from Southern Brazil
(2019-12-01)
Centropomus undecimalis fish inhabit the highly contaminated Santos-São Vicente Estuarine System (SESS) and could be a good biomonitor of contaminants. This study aimed to investigate the cytogenotoxic potential of superficial ...
