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 soon » decrease food (Expand search), decrease sod (Expand search), decreases soil (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 on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (Expand search)
soon based » boron based (Expand search), icon based (Expand search), common based (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 lesions decrease ) OR ( decrease on decrease soon based ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease lesions decrease ) OR ( decrease on decrease soon based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease lesions decrease ) OR ( decrease on decrease soon based ))*.
