Perhaps you should try some spelling variations:
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at objects » art objects (Expand search), lat objects (Expand search), t objects (Expand search)

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

• Removing quotes may allow a broader search: (( increase during decrease NOT decrease ) OR ( decrease of decrease at objects ))~.
