Assessment of Cardiac Autonomic Function in Relation to Methylmercury Neurotoxicity
Toxics, 2018 After the European Food Safety Authority reviewed reports of methylmercury and heart rate variability (HRV) in 2012, the panel concluded that, although some studies of cardiac autonomy suggested an autonomic effect of methylmercury, the results were ...

Bioconcentração e biomagnificação de metilmercúrio na baía de Guanabara, Rio de Janeiro
Química Nova, 2011 Methylmercury was determined in water and aquatic biota from Guanabara Bay. Trophic transfer of methylmercury was observed between trophic levels from prey (microplankton, mesoplankton and fish with different feeding habits) to top predator (pelagic ...

Biotransformation of methylmercury in vitro.
The Tohoku Journal of Experimental Medicine, 1976 Inorganic mercury formation from methylmercury by the mouse liver and kidney was studied in vitro. With chopped liver or kidney, inorganic mercury was formed from added methylmercury, but when the tissue was homogenized, the activity was diminished. Equimolar addition of selenium had no effect on the reaction.

Methylmercury Resistance in Desulfovibrio desulfuricans Strains in Relation to Methylmercury Degradation [PDF]
Applied and Environmental Microbiology, 1993 Two strains of Desulfovibrio desulfuricans , one known to synthesize monomethylmercury from ionic mercury, were grown to determine methylmercury toxicity and for comparison with an anaerobic strain of Clostridium pasteurianum , a H 2 producer, and with the broad ...

Spina bifida as a multifactorial birth defect: Risk factors and genetic underpinnings
Pediatric Discovery, EarlyView.Abstract Spina bifida is a birth defect resulting from abnormal embryonic development of the neural tube. Though spina bifida is divided into several subtypes, myelomeningocele—the most severe form of spina bifida often associated with a markedly diminished quality of life—accounts for a significant portion of cases.
