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)
replacing based » replicon based (Expand search), playing based (Expand search), replacing and (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (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 will decrease OR decrease ) OR ( decrease lesions decrease replacing based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease will decrease OR decrease ) OR ( decrease lesions decrease replacing based ))*.
