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)
fluid processing » food processing (Expand search), feed processing (Expand search), blood processing (Expand search)
decrease fluid » decrease lipid (Expand search), decrease food (Expand search), decrease blood (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (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)

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 lesions decrease fluid processing ) OR ( decrease pain decrease AND decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease fluid processing ) OR ( decrease pain decrease and decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease fluid processing ) OR ( decrease pain decrease and decrease ))*.
