Selenium and Mercury in the Brazilian Amazon: Opposing Influences on Age-Related Cataracts
(US DEPT HEALTH HUMAN SCIENCES PUBLIC HEALTH SCIENCE, 2010)
BACKGROUND: Age-related cataracts (ARCs) are an important cause of blindness in developing countries. Although antioxidants may be part of the body's defense to prevent ARC, environmental contaminants may contribute to ...

Human exposure to mercury in the Brazilian Amazon: a historical perspective
(Pan American Health OrganizationWashingtonEUA, 2004)
Hematological parameters in Nile Tilápia, Oreochromis niloticus exposed to sub-letal concentrations of mercury
(Brazilian Archives of Biology and Technology, 2007-07-01)
A toxicidade do mercúrio foi avaliada em tilápia, Oreochromis niloticus (Linnaues, 1758) através da análise dos parâmetros hematológicos após exposição a diferentes concentrações sub-letais, durante um período de 14 dias. ...

Toxicidade do HgCl2 em ratas Wistar analisadas 12 e 48 horas após a exposição: possível efeito preventivo do zinco
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2016-02-10)
Mercury is a metal without any biological function. The exposure to mercury in any of different chemical forms can induce toxic effects on living organisms. This toxicity is commonly attributed to the high affinity that ...
Intron 4 polymorphism of the endothelial nitric oxide synthase (eNOS) gene is associated with decreased NO production in a mercury-exposed population
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Nitric oxide (NO), produced by endothelial nitric oxide synthase (eNOS), is a potent vasodilator and plays a prominent role in regulating the cardiovascular system. Decreased basal NO release may predispose to cardiovascular ...
Ratas lactantes e não lactantes diferem quanto à sensibilidade ao HgCl2: efeito protetor do ZnCl2
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2012-08-17)
Mercury is a divalent metal found in the liquid state at room temperature without biological function. Occupational exposure to this metal occurs mainly in industrial activities and agriculture. Its toxicity seems to be ...
Determination of total and inorganic mercury in whole blood by cold vapor inductively coupled plasma mass spectrometry (CV ICP-MS) with alkaline sample preparation
(ROYAL SOC CHEMISTRY, 2009)
A simple method with a fast sample preparation procedure for total and inorganic mercury determinations in blood samples is proposed based on flow injection cold vapor inductively coupled plasma mass spectrometry (FI-CVICP-MS). ...
Mercury exposure and oxidative stress in communities of the Brazilian Amazon
(ELSEVIER SCIENCE BV, 2010)
This study was designed to assess possible associations between biomarkers of mercury (Hg) exposure and oxidative stress in fish-eating Amazonian communities. Clinical samples were obtained from riparians living in the ...
