Plasma cholinesterase activity as an environmental impact biomarker in juvenile green turtles (Chelonia mydas)

Pesqui. vet. bras; 40 (1), 2020
The objective of this study was to evaluate the enzymatic activity of plasma cholinesterase in Chelonia mydas marine turtles belonging to two populations, according to their capture sites, under the absence and probable influence of anthropic effects. A total of 74 animals were used and later divided int...

Atividade da colinesterase plasmática como biomarcador de impacto ambiental em tartarugas verdes (Chelonia mydas) no litoral do Arquipélago de Fernando de Noronha, Pernambuco

Pesqui. vet. bras; 35 (4), 2015
Biomarcadores podem ser usados de forma preditiva, permitindo que sejam tomadas ações de controle antes que ocorram danos ambientais irreversíveis com consequências ecológicas severas, no entanto, espécies sentinelas são necessárias para avaliação desses marcadores. As tartarugas marinhas são ...

Niveles de colinesterasa plasmática en mujeres embarazadas y no embarazadas expuestas a plaguicidas en la zona del Páramo: Mérida-Venezuela
Plasma cholinesterase levels pregnant and non-pregnant women exposed to pesticides Páramo area: Mérida-Venezuela

Rev. Inst. Nac. Hig; 44 (1), 2013
Se realizó un estudio comparativo y experimental para determinar el nivel plasmático de colinesterasa (con la técnica de Ensayo del reactivo de Ellman) en 51 mujeres embarazadas y 52 no embarazadas, expuestas en forma crónica a insecticidas organofosforados y carbamatos en la zona del páramo merideÃ...

Study of the correlation between blood cholinesterases activity, urinary dialkyl phosphates, and the frequency of micronucleated polychromatic erythrocytes in rats exposed to disulfoton

Braz. j. pharm. sci; 49 (1), 2013
Organophosphates (OPs) are widely used as pesticides, and its urinary metabolites as well as the blood cholinesterases (ChEs) activity have been reported as possible biomarkers for the assessment of this pesticide exposure. Moreover, the OPs can induce mutagenesis, and the bone marrow micronucleus test i...

Modificación de un método para colinesterasa plasmática empleando la reducción del ferricianuro como indicador
Modification in the method for serum cholinesterase in ferricyanide reduction how indicatory

Se describe la modificación de un método para la cuantificación de colinesterasa plasmática mediante monitoreo continuo empleando ferricianuro como indicador. La tiocolina liberada de la propioniltiocolina reduce el ferricianuro a ferrocianuro y la disminición de absorbancia a 405 nm es proporcional...
