The cerebellum is known as the major target regions of methylmercury (MeHg) toxicity, but the mechanisms are still not fully understood. We studied the effects of MeHg exposure in the cerebellum of common marmoset (Callithrix jacchus) using a shotgun proteomic approach with liquid chromatography coupled to mass spectrometry. A total of 1000 common proteins were identified in all samples, and 10...

The interaction between mercury and selenium may involve a variety of toxicologically and biochemically distinct processes. In this paper, the interaction between inorganic mercury and sodium selenite, the interaction most extensively studied, as well as the interaction between methylmercury (MeHg) and selenium, the interaction perhaps most significant for non-occupational human populations, wi...

in this study, correlation between methylmercury (mehg) accumulation in the kidney and liver and several blood biochemical parameters juvenile beluga (huso huso) including aspartate aminotransferase (ast), alanine aminotransferase (alt), alkaline phosphatase (alp), lactate dehydrogenase (ldh), glucose (glu), and cortisol was investigated. to do this, juvenile beluga were fed with two different ...

This study examined methylmercury (MeHg) concentrations in fish, the daily MeHg exposure dose, and the risk-benefit of MeHg, ω-3 polyunsaturated fatty acid (ω-3 PUFA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) related to fish intake among pregnant and infertile women in Taiwan. The measured MeHg concentrations in fish did not exceed the Codex guideline level of 1 mg/kg. Swordf...

Industrial pollution due to heavy metals such as mercury is a major concern for the environment and public health. Mercury, in particular methylmercury (MeHg), primarily affects brain development and neuronal activity, resulting in neurotoxic effects. Because chemokines can modulate brain functions and are involved in neuroinflammatory and neurodegenerative diseases, we tested the possibility t...

Mercury, an environmental health hazard, is a neurotoxic heavy metal. In this study, the effect of methylmercury (MeHg) exposure was analyzed on sexual behavior in Drosophila melanogaster (fruit fly), because neurons play a vital role in sexual functions. The virgin male and female flies were fed a diet mixed with different concentrations of MeHg (28.25, 56.5, 113, 226, and 339 µM) for four day...

Methylmercury (MeHg) is a ubiquitous contaminant largely found in aquatic environments, especially species at high trophic level such as salmonids. The aim of this study was to evaluate the effects MeHg on adipocyte differentiation and lipid metabolism rainbow trout. Primary cultured preadipocytes were exposed increasing concentrations during six days with or without hormonal cocktail. Main res...

Methylmercury concentrations [MeHg] in whole water were measured 28 prairie wetland ponds central Saskatchewan between 2006 and 2012. Ponds fell into four land use categories (established grass, recent traditional cultivated, certified organic cultivated) two level patterns (“Mainly Wet” stayed wet at least until October “Mainly Dry” dried up each summer). Despite similar atmospheric Hg deposit...

Methylmercury (MeHg) is a persistent environmental toxin present in seafood that can compromise the developing nervous system in humans. The effects of MeHg toxicity varies among individuals, despite similar levels of exposure, indicating that genetic differences contribute to MeHg susceptibility. To examine how genetic variation impacts MeHg tolerance, we assessed developmental tolerance to Me...

The transformation of inorganic mercury (Hg) to methylmercury (MeHg) plays a key role in determining the amount of Hg that is bioaccumulated in aquatic food chains. An accurate knowledge of Hg methylation mechanisms is required to predict the conditions that promote MeHg production in aquatic environments. In this study, we conducted experiments to examine the oxidation and methylation of disso...
