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 first » disease first (Expand search), decrease risk (Expand search), decrease its (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease akt » decrease at (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » not decrease (Expand search), any decrease (Expand search), salt decreases (Expand search)
first object » first objects (Expand search), direct object (Expand search), first direct (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 AND decrease akt decrease ) OR ( decrease lesions decrease first object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease akt decrease ) OR ( decrease lesions decrease first object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease akt decrease ) OR ( decrease lesions decrease first object ))*.
