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 depletion. Layers of the atmosphere (not to scale). The Earth's ozone layer is mainly found in the lower portion of the stratosphere from approximately 20 to 30 km (12 to 19 mi).
