Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
disease lesions » disease lessons (Expand search), diseases lessons (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
co processing » and processing (Expand search), video processing (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease co » decrease pro (Expand search), decrease toc (Expand search), decrease low (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: (( disease lesions decrease co processing ) OR ( decrease during decrease AND decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( disease lesions decrease co processing ) OR ( decrease during decrease and decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( disease lesions decrease co processing ) OR ( decrease during decrease and decrease ))*.
