Perhaps you should try some spelling variations:
decrease process » decrease processes (Expand search), increase process (Expand search), disease process (Expand search)
process effect » process effects (Expand search), processing effect (Expand search), processes effects (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrees that » devices that (Expand search), trees that (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (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: "(( decrees that decrease akt decrease ) OR ( decrease to decrease process effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrees that decrease akt decrease ) OR ( decrease to decrease process effect ))*.
