Perhaps you should try some spelling variations:
decrease physicians » decrease physical (Expand search), disease physicians (Expand search)
decrease processes » disease processes (Expand search), decay processes (Expand search), increase process (Expand search)
physicians program » physical program (Expand search), physicians from (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decreases disease (Expand search)
protein decrease » protein increase (Expand search), protein secretases (Expand search), protein increases (Expand search)
prion protein » in protein (Expand search), on protein (Expand search), non protein (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease NOT decrease decrease processes ) OR ( prion protein decrease physicians program ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease decrease processes ) OR ( prion protein decrease physicians program ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease decrease processes ) OR ( prion protein decrease physicians program ))*.
