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 flow » decreases flow (Expand search), decrease low (Expand search), decrease food (Expand search)
flow increase » show increased (Expand search), cows increase (Expand search)
increase old » increases bold (Expand search), increase bond (Expand search), increase food (Expand search)
old objects » world objects (Expand search), older objects (Expand search), road objects (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 _ decrease lesions decrease ) OR ( decrease flow increase old objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease lesions decrease ) OR ( decrease flow increase old objects ))*.
