Methylmercury and the skeletal muscle receptor
Journal of Pharmacy and Pharmacology, 1976 AbstractMethylmercury at a bath concentration of 2 × 10−5 m was capable of inhibiting muscular contractions of the isolated rat phrenic-nerve hemidiaphragm preparation. At the height of inhibition, nerve action potential could still be recorded and the muscles continued to respond to direct stimulation. The inhibition was not reversible with l-cysteine

Anticoagulant Rodenticides Contribute to a Decline in an Urban Carnivore
Animal Conservation, Volume 29, Issue 5, Page 545-556, October 2026.Anticoagulant rodenticides (ARs) have been shown to negatively affect carnivores globally and are closely tied to human activity and development. We examined drivers of annual survival in bobcats persisting on a residentially developed barrier island over 16 years.

Investigation of the Morphology of the Heart of Zebrafish Embryos Exposed to Different Concentrations of Methylmercury [PDF]
, 2014 Mercury is a well-known neurotoxicant. In its elemental form, mercury is easily distributed into the atmosphere due to its relatively low boiling point. Once elemental mercury becomes airborne it can travel long distances to eventually be deposited into ...

Methylmercury distribution, metabolism, and neurotoxicity in the mouse brain
, 1983 Methylmercury distribution, biotransformation, and neurotoxicity in the brain of male Swiss albino mice were investigated. Mice were orally dosed with [203Hg]methylmercury chloride (10 mg/kg) for 1 to 9 days.

Psychiatric aspects of methylmercury poisoning [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1974 Forty-three patients with methylmercury poisoning were studied; 74·4% showed some degree of depression. Their blood levels of mercury were higher than the average values for the whole group, and considerably higher than the blood levels of the non-depressed patients.

Methylmercury-Cholinesterase Interactions in Rats
Environmental Health Perspectives, 1975 The interaction of methylmercury hydroxide (MMH) and cholinesterases was studied in male and female rats. MMH administered subcutaneously in doses of 10 mg/kg for 2 days reduced the level of plasma cholinesterase (ButChE) by 68% in females and 47% in males while brain acetylcholinesterase (AChE) was unaffected.

Deep sea cold seeps are a sink for mercury and source for methylmercury
Communications Earth & EnvironmentThe effect of seafloor cold seeps on the biogeochemical cycling of mercury (Hg) remains enigmatic. Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments ...
