Perhaps you should try some spelling variations:
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease defeat » decreased fear (Expand search), decrease fear (Expand search), decreases dentate (Expand search)
defeat protocol » death protocol (Expand search), direct protocol (Expand search), referral protocol (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (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)

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 during decrease will decrease ) OR ( decrease NOT decrease defeat protocol ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease during decrease will decrease ) OR ( decrease not decrease defeat protocol ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during decrease will decrease ) OR ( decrease not decrease defeat protocol ))*.
