Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), decay processes (Expand search), increase process (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decreases disease (Expand search)
activation levels » coactivation levels (Expand search), motivation levels (Expand search), motivation level (Expand search)
levels decrease » levels increase (Expand search), leaves decrease (Expand search), levels increased (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
decreases low » decreases of (Expand search), decreases blood (Expand search), decreases local (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decreases low decrease decrease processes ) OR ( activation levels decrease decrease after ))~.
