CAUSES OF HIGH AMMONIA. Ammonia is a normal by-product of processing nitrogen in the body, and is excreted as waste in the urine, in healthy people. However, elevated blood ammonia levels can occur when the kidneys or liver are not working properly, allowing this waste to remain in the bloodstream, which can be poisonous to your cells.
Spina bifida research scientists are looking at a possible genetic cause of spina bifida. The goal of this research is to find the genetic factors that make some children more susceptible to neural tube defects than others.
Background. Spina bifida is a treatable spinal cord malformation that occurs in varying degrees of severity. Classified as a defect of the neural tube (ie, the embryonic structure that develops into the spinal cord and brain), it was recognized as long as 4000 years ago.ackground.
