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)
heat processing » meat processing (Expand search), text processing (Expand search), event processing (Expand search)
decreased ratio » decreased rate (Expand search), decreased native (Expand search), decreased rankl (Expand search)
ratio decrease » rate decrease (Expand search), rapid decrease (Expand search), ratio increase (Expand search)
decrease heat » decreased heart (Expand search), decreases wheat (Expand search), decrease at (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 lesions decrease heat processing ) OR ( decreased ratio decrease NOT decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease heat processing ) OR ( decreased ratio decrease not decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease heat processing ) OR ( decreased ratio decrease not decrease ))*.
