Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decreases with » increases with (Expand search), decreases in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (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 art » decrease at (Expand search), decreased akt (Expand search), decreased ant (Expand search)
art objects » smart objects (Expand search), and objects (Expand search), belt objects (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 akt decrease response decrease ) OR ( decreases with decrease art objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease response decrease ) OR ( decreases with decrease art objects ))*.
