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.
Fluorine does have its problems, as environmentalists are quick to point out. Chlorofluorocarbons (CFCs) were identified as being a significant contributor to ozone depletion. Through a process called photolysis, a breakage of one or more covalent bonds occurs (Cl2 ? 2Cl).
