Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (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)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
and objects » and object (Expand search), and subjects (Expand search), and objectives (Expand search)
case at » case and (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 at decrease ) OR ( decrease will decrease AND objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions case at decrease ) OR ( decrease will decrease and objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions case at decrease ) OR ( decrease will decrease and objects ))*.
