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 in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search)
decrease toc » decrease of (Expand search), decreased to (Expand search), decrease on (Expand search)
toc bases » noc based (Expand search), doc base (Expand search), iec bases (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 decrease AND decrease ) OR ( decrease the decrease toc bases ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease and decrease ) OR ( decrease the decrease toc bases ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease and decrease ) OR ( decrease the decrease toc bases ))*.
