The present study was undertaken to investigate the precursory effects of methylmercury poisoning by measuring the locomotor activity of rats. Methylmercury was administered to male rats mixed in the rat food. The period of administration was 30 days. The effects on the rats exposed to a level of 100 ppm of methylmercury were evaluated from the 6th week to the time of death, based on the locomo...

BACKGROUND Methylmercury (MeHg), a worldwide contaminant found in fish and seafood, has been linked to an increased risk of cardiovascular mortality. OBJECTIVE We examined 42 Faroese whaling men (30-70 years of age) to assess possible adverse effects within a wide range of MeHg exposures from consumption of pilot whale meat. METHODS We assessed exposure levels from mercury analysis of toena...

Mercury is present in the earth's crust and is methylated by bacteria in aquatic environments to methylmercury (MeHg). It is then concentrated by the food chain so predatory fish and sea mammals have the highest levels. Thus, consuming seafood leads to exposure. MeHg readily crosses the placenta and the blood-brain barrier and is neurotoxic. The developing fetal nervous system is especially sen...

Seafood consumption is the primary route of methylmercury (MeHg) exposure for most populations. Inherent uncertainties in dietary survey data point to the need for an empirical tool to confirm exposure sources. We therefore explore the utility of Hg stable isotope ratios in human hair as a new method for discerning MeHg exposure sources. We characterized Hg isotope fractionation between humans ...

VVe searched a yeast genomic library fbr genes that conferred methylmercury resistance to yeast, Ymr258c was identified as a factor that conferred strong methylmercury resistance when overexpressed in budding yeast. Ymr258c is regarded as one of the F-box proteins, i.e,, component factors of the SkpllCullin!F-box protein (SCF) complex that functions as a ubiquitin ligase in the ubiquitin-protea...
