Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions case » lesion case (Expand search), lesions caused (Expand search), lesions based (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)
case stream » waste stream (Expand search), based stream (Expand search), cambe stream (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 lesions case stream processing ) OR ( decrease AND decrease NOT decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions case stream processing ) OR ( decrease and decrease NOT decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions case stream processing ) OR ( decrease and decrease NOT decrease ))*.
