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 diel » decrease il (Expand search), decrease due (Expand search), decreases yield (Expand search)
diel pattern » diet patterns (Expand search), yield pattern (Expand search), axial pattern (Expand search)
decrease or » decrease of (Expand search), decrease pro (Expand search), decrease toc (Expand search)
or decrease » not decrease (Expand search), to decrease (Expand search), _ decrease (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease and (Expand search)
on decrease » on decreased (Expand search), of decrease (Expand search), and decrease (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 OR decrease lesions decrease ) OR ( decrease on decrease diel pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease lesions decrease ) OR ( decrease on decrease diel pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease lesions decrease ) OR ( decrease on decrease diel pattern ))*.
