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 akt » decrease after (Expand search), decrease with (Expand search), decreased and (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease at » decrease in (Expand search), decrease of (Expand search), decrease _ (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
and wrapped » and wrapper (Expand search), and trapped (Expand search), and warped (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 akt decrease at decrease ) OR ( decrease during decrease AND wrapped ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease akt decrease at decrease ) OR ( decrease during decrease and wrapped ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease at decrease ) OR ( decrease during decrease and wrapped ))*.
