Perhaps you should try some spelling variations:
decreased response » increased response (Expand search), increases response (Expand search), decreased responsiveness (Expand search)
akt decreased » and decreased (Expand search), are decreased (Expand search), not decreased (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease 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)
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 decreased response decrease ) OR ( decrease with decrease art objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decreased response decrease ) OR ( decrease with decrease art objects ))*.
