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.
The depletion of ozone in the ozone layer results in increased amounts of this damaging radiation reaching Earth's surface and an increased occurrence of these problems in humans and other living beings.he stratospheric ozone layer has become substantially depleted throughout much of the globe since the 1980s because of enhanced human production and use of ozone-depleting chemicals, such as chlorofluorocarbons, halons, and others, during the 20th century.
