Perhaps you should try some spelling variations:
lesions decreased » lesions decrease (Expand search), lesions increase (Expand search), deletion decreased (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
cd1a processing » dna processing (Expand search), cocoa processing (Expand search), data processing (Expand search)
decreased cd1a » decreased cardiac (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 lesions decreased cd1a processing ) OR ( decrease AND decrease _ decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decreased cd1a processing ) OR ( decrease AND decrease _ decrease ))*.
