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)
protein decrease » protein increase (Expand search), protein secretases (Expand search), protein increases (Expand search)
decrease physics » decrease physical (Expand search), increase physical (Expand search)
physics problem » physics problems (Expand search)
prion protein » in protein (Expand search), on protein (Expand search), non protein (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease decrease processes ) OR ( prion protein decrease physics problem ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease decrease processes ) OR ( prion protein decrease physics problem ))*.
