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 older » decreases under (Expand search), decrease after (Expand search), decrease or (Expand search)
older objects » older subjects (Expand search), golden objects (Expand search), other object (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 AND decrease AND decrease ) OR ( decrease lesions decrease older objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease AND decrease ) OR ( decrease lesions decrease older objects ))*.
