Perhaps you should try some spelling variations:
decrease processes » disease processes (Expand search), decay processes (Expand search), increase process (Expand search)
processes effect » processes effects (Expand search), processes affect (Expand search), process effect (Expand search)
akt decreased » and decreased (Expand search), are decreased (Expand search), not decreased (Expand search)
decreased and » decreases and (Expand search), decrease and (Expand search), decreased in (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not 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 akt decreased AND decrease ) OR ( decrease toc decrease processes effect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease akt decreased and decrease ) OR ( decrease toc decrease processes effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decreased and decrease ) OR ( decrease toc decrease processes effect ))*.
