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 ratio » decreased ratio (Expand search), decrease at (Expand search), decreased rate (Expand search)
cell decreased » cells decreases (Expand search), cells decrease (Expand search), jelly decreases (Expand search)
ratio decrease » rate decrease (Expand search), rapid decrease (Expand search), ratio increase (Expand search)
decrease cell » decreases cell (Expand search)
il processing » oil processing (Expand search), l processing (Expand search), mill processing (Expand search)
decreased il » decreased in (Expand search), increased il (Expand search), decreased risk (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 cell decreased il processing ) OR ( decrease ratio decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cell decreased il processing ) OR ( decrease ratio decrease lesions decrease ))*.
