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)
end processing » and processing (Expand search), seed processing (Expand search), feed processing (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
pain decrease » can decrease (Expand search), taping decrease (Expand search), strain decrease (Expand search)

decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (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 pain decrease end processing ) OR ( decrease NOT decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease pain decrease end processing ) OR ( decrease not decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pain decrease end processing ) OR ( decrease not decrease lesions decrease ))*.
