Perhaps you should try some spelling variations:
decrease during » increase during (Expand search), increases during (Expand search), disease during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
not decreased » not decrease (Expand search), to decreased (Expand search), not increased (Expand search)
decreased and » decreases and (Expand search), decrease and (Expand search), decreased in (Expand search)
decrease belt » decrease cell (Expand search), decrease at (Expand search), decrease akt (Expand search)
decrease not » decrease of (Expand search), decrease at (Expand search), decrease akt (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
objects » object (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 NOT decreased AND decrease ) OR ( decrease during decrease belt objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decreased and decrease ) OR ( decrease during decrease belt objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decreased and decrease ) OR ( decrease during decrease belt objects ))*.
