Perhaps you should try some spelling variations:
activation patterns » activity patterns (Expand search), interaction patterns (Expand search), methylation patterns (Expand search)
decrease activation » increase activation (Expand search), increased activation (Expand search), urease activation (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease _ decrease toc decrease ) OR ( decrease akt decrease activation patterns ))~.
