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.
For most ALS genes, only one mutated copy is needed to cause disease. This is called a âdominantâ gene. For other genes, both copies must be mutated to cause disease. This is called a ârecessiveâ gene. During formation of eggs and sperm, gene pairs split up, so that an egg (or sperm) contains only one gene copy.
