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 when » decrease the (Expand search), decreases wheat (Expand search), decrease their (Expand search)
when objects » when subjects (Expand search), wooden objects (Expand search), within objects (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain 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 at decrease ) OR ( decrease in decrease when objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease at decrease ) OR ( decrease in decrease when objects ))*.
