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 and » decreases and (Expand search), decrease the (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
and manners » and managers (Expand search), and markers (Expand search), and masters (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: (( decrease of decrease lesions decrease ) OR ( decrease in decrease AND manners ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease of decrease lesions decrease ) OR ( decrease in decrease and manners ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease lesions decrease ) OR ( decrease in decrease and manners ))*.
