Perhaps you should try some spelling variations:
migration projects » migration project (Expand search), migration process (Expand search), mediation projects (Expand search)
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 the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and 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 migration projects ) OR ( decrease OR decrease the decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease migration projects ) OR ( decrease OR decrease the decrease ))*.
