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.
Causes of ALS. ALS is a somewhat diverse and decidedly mystifying disease. In more than nine out of every 10 cases diagnosed, no clear identifying cause of the disease is apparent, that is, patients lack an obvious genetic history, complete with affected family members. Also, nothing about the way patients live their lives gives scientists and clinicians clues as to what causes ALS.
