Perhaps you should try some spelling variations:
decrease activation » increase activation (Expand search), increased activation (Expand search), urease activation (Expand search)
activation patterns » activity patterns (Expand search), interaction patterns (Expand search), methylation patterns (Expand search)
nts decreases » rats decreases (Expand search), benth decreases (Expand search), loss decreases (Expand search)
decrease nts » decrease its (Expand search), decrease at (Expand search), decrease std (Expand search)
decreases on » decreases in (Expand search), decreases of (Expand search), decreases bone (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)
on decrease » on decreased (Expand search), of decrease (Expand search), or 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 nts decreases on decrease ) OR ( decrease AND decrease activation patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease nts decreases on decrease ) OR ( decrease and decrease activation patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease nts decreases on decrease ) OR ( decrease and decrease activation patterns ))*.
