Duchenne muscular dystrophy (DMD) is a severe type of muscular dystrophy predominantly affecting boys. [3] [7] [8] The onset of muscle weakness typically begins around age four, with rapid progression. [2] Initially, muscle loss occurs in the thighs and pelvis, extending to the arms, [3] which can lead to difficulties in standing up. [3]
Dimethylmercury is an extremely toxic organomercury compound with the formula (CH 3) 2 Hg. A volatile, flammable, dense and colorless liquid, dimethylmercury is one of the strongest known neurotoxins. Less than 0.1 mL is capable of inducing severe mercury poisoning resulting in death. [2]
