Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (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)
at processing » meat processing (Expand search), heat processing (Expand search), wet processing (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease on (Expand search)

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