Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease smart » decreased heart (Expand search), decrease akt (Expand search), decrease at (Expand search)
smart object » smart objects (Expand search), art object (Expand search), art objects (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), or decrease (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 lesions decrease NOT decrease ) OR ( decrease on decrease smart object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease NOT decrease ) OR ( decrease on decrease smart object ))*.
