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 can » decrease and (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » and decrease (Expand search), can increase (Expand search), to decrease (Expand search)
decrease by » decreased by (Expand search), decrease of (Expand search), decrease _ (Expand search)
by decrease » by decreased (Expand search), may decrease (Expand search), any decrease (Expand search)
in capped » n capped (Expand search), in trapped (Expand search), end capped (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 can decrease lesions decrease ) OR ( decrease by decrease in capped ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease can decrease lesions decrease ) OR ( decrease by decrease in capped ))*.
