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.
Depletion of the ozone layer means that for a given vertical path from the Earth's surface to the Sun, less ozone is encountered along the way with each passing year. This a â¦ llows more UV-B to pass through to Earth's surface, more damage to the DNA of all surface life, and so on.epletion is a long term decrease in ozone concentrations. It has nothing to do with the daily pluses and minuses of ozone concentrations. It is a forcing function that destroys ozone before it can absorb UV-B from the Sun, and there are a few primary candidates for ozone depleters.
