What diseases can a CT scan detect? A bowel perforation consists of a hole that runs all the way through the bowel or large intestine. The danger is that perforation can cause peritonitis, an inflammation of the membrane lining the entire abdominal cavity. If acid from the stomach, bile or bacteria enters the cavity, then peritonitis can take place -- a life-threatening condition.
The statement that a prion is an infectious, self-reproducing protein structure is true. Prion is short for short for proteinaceous infectious particle. All known prion diseases in mammals affect the structure of the brain or other neural tissue. Hope this answers the question. Comments.
Prions are infectious agents composed exclusively of a single sialoglycoprotein called PrP 27-30. They contain no nucleic acid. PrP 27-30 has a mass of 27,000 - 30,000 daltons and is composed of 145 amino acids with glycosylation at or near amino acids 181 and 197. The carboxy terminus contains a phosphatidylinositol glycolipid whose components are ethanolamine, phosphate, myo-inositol and stearic acid.
