Perhaps you should try some spelling variations:
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
akt decreased » and decreased (Expand search), are decreased (Expand search), not decreased (Expand search)
decreased ant » decreased and (Expand search), decreased akt (Expand search), decreased akt1 (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
ant object » an object (Expand search), and object (Expand search), art object (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 OR decrease faster decrease ) OR ( decrease akt decreased ant object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease faster decrease ) OR ( decrease akt decreased ant object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease faster decrease ) OR ( decrease akt decreased ant object ))*.
