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.
Familial ALS is caused by a mutation. A mutation is a genetic change or abnormality in a particular gene. Sorting out which gene is to blame is complicated. Humans have about 50,000 genes, and in most people with familial ALS scientists have not yet identified which gene is responsible for causing ALS.
