Perhaps you should try some spelling variations:
cooperative processes » cooperative process (Expand search), creative processes (Expand search), collective processes (Expand search)
decrease cooperative » decrease cooperation (Expand search), disease cooperative (Expand search), decreases postoperative (Expand search)
decrease akt » decrease at (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and increase » and increases (Expand search), and increased (Expand search)
increase to » increase the (Expand search), increase tax (Expand search), increase tnf (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 decrease cooperative processes ) OR ( decrease AND increase to decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease akt decrease cooperative processes ) OR ( decrease and increase to decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease cooperative processes ) OR ( decrease and increase to decrease ))*.
