Protective effects of organoselenium compounds against methylmercury-induced oxidative stress in mouse brain mitochondrial-enriched fractions [PDF]

open access: greenBrazilian Journal of Medical and Biological Research, 2011
We evaluated the potential neuroprotective effect of 1-100 µM of four organoselenium compounds: diphenyl diselenide, 3’3-ditri-fluoromethyldiphenyl diselenide, p-methoxy-diphenyl diselenide, and p-chloro-diphenyl diselenide, against methylmercury-induced

Studies on methylmercury compounds in Ictalurus nebulosus (Le Sueur, 1819) exposed to mercury chloride [PDF]

open access: goldActa Ichthyologica et Piscatoria, 1980
Individuals of Ictalurus nebulosus (Le Sueur, 1819) were bathed in solutions of HgCl2 and CH3HgCl. Methylmercury compounds were detected in muscles, liver, and kidneys of those individuals exposed to HgCl2, which indicates mercury methylation to have ...

Cytotoxicity and genotoxicity of low doses of mercury chloride and methylmercury chloride on human lymphocytes in vitro [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2005
Mercury is a xenobiotic metal that is a highly deleterious environmental pollutant. The biotransformation of mercury chloride (HgCl2) into methylmercury chloride (CH3HgCl) in aquatic environments is well-known and humans are exposed by consumption of ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Genotoxicity of Mercury and Its Derivatives Demonstrated In Vitro and In Vivo in Human Populations Studies. Systematic Review

open access: yesToxics, 2021
Beside partial coverage in three reviews so far (1994, 2009, 2019), there is no review on genotoxic studies dealing with mercury (Hg) and human exposure using the most usual genotoxic assays: sister chromatid exchanges (SCE), chromosomal aberrations (CA),

Chemical Toxicants Used for Food Preservation in Africa. Is it a Case of Ignorance or Food Fraud? A Review. [PDF]

open access: yesHealth Sci Rep
ABSTRACT Background and Aims This review examined the use of chemical preservatives in food preservation and the food fraud risks associated with its misuse in Africa. In Africa, there is growing reliance on the use of synthetic chemical preservation such as benzoates, nitrates or sorbates to preserve foods to improve the storage life of the foods ...
