Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease oat » decrease at (Expand search), decrease of (Expand search), decrease akt (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
oat effect » coat effect (Expand search), oat effects (Expand search), out effect (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 NOT decrease in decrease ) OR ( decrease lesions decrease oat effect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease in decrease ) OR ( decrease lesions decrease oat effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease in decrease ) OR ( decrease lesions decrease oat effect ))*.
