The Cavitron Ultrasonic Surgical Aspirator is a unique modality for precise tissue removal which results in increased visibility, reduced bleeding, and shorter operating time when dealing with vascular lesions or organs.
Mutations in the gene for the enzymes superoxide dismutase 1 (SOD1) or copper zinc superoxide dismutase have been found in approximately 15-20 percent of the familial cases of ALS. Some quick math shows, then, that approximately 1 to 2 percent of all cases of ALS involve this particular gene mutation.
In 1993 a large collaborative group demonstrated that some inherited forms of ALS are caused by mutations. The genetic change alters an abundant enzyme within cells called copper-zinc superoxide dismutase (cu-zn superoxide dismutase, now called commonly SOD1).
