Focal intestinal metaplasia is the potentially reversible change from a fully differentiated stomach cell type to an intestinal cell type. It is associated with significantly increased risk of cancer. . Proper diagnosis and treatment can reduce the risk of gastric cancer. slide 1 of 6.
The ozone depletion potential (ODP) of a compound is a simple measure of. its ability to destroy stratospheric ozone. It is a relative measure: the ODP of CFC-11 is defined to be 1.0, and the ODP's of other compounds. are calculated with respect to this reference point. Thus a compound with.
Ozone occurs in two layers of the atmosphere. The ozone that is commonly associated with ozone depletion and the ozone hole is in the stratosphere, a layer that extends upward from about 10 to 30 miles (15 to 50 kilometers) above the earth.zone occurs in two layers of the atmosphere.
