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 subjects » elderly subjects (Expand search), disorder subjects (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (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 akt decrease AND decrease ) OR ( decrease lesions decrease older subjects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease AND decrease ) OR ( decrease lesions decrease older subjects ))*.
