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 not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low decrease » flow decrease (Expand search), loss decrease (Expand search), to decrease (Expand search)
decrease en » decrease in (Expand search), decrease on (Expand search), decrease when (Expand search)
en object » an object (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 NOT decrease ) OR ( decrease low decrease en object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease not decrease ) OR ( decrease low decrease en object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease not decrease ) OR ( decrease low decrease en object ))*.
