Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease milk (Expand search)
decrease act » decrease akt (Expand search), decrease at (Expand search), decreased akt (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il decrease » l decrease (Expand search), oil decreases (Expand search), soil decrease (Expand search)
act based » art based (Expand search), ict based (Expand search), ct based (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 il decrease ) OR ( decrease lesions decrease act based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease will decrease il decrease ) OR ( decrease lesions decrease act based ))*.
