Perhaps you should try some spelling variations:
decrease rapid » decrease lipid (Expand search), decreased ratio (Expand search), decrease and (Expand search)
rapid decrease » rapidly decrease (Expand search), rapid increase (Expand search), ratio decrease (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 on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on object » an object (Expand search), en object (Expand search), in object (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 _ decrease akt decrease ) OR ( decrease rapid decrease on object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease akt decrease ) OR ( decrease rapid decrease on object ))*.
