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.
There are three types of ALS: familial, sporadic and Guamanian. Familial is inherited genetically and is the least common form, occurring in only about 5-10% of cases. Researchers are still uncertain as to what causes sporadic and Guamanian ALS. There are several common conditions that accompany the illness and these are theorized to be related to the of developing the disease. Some of the most common causes of ALS may include: Heavy metal toxicity.
