Perhaps you should try some spelling variations:
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
end processing » and processing (Expand search), seed processing (Expand search), feed processing (Expand search)
decrease end » decrease and (Expand search), decreased and (Expand search), decrease need (Expand search)
depressed or » depressed nk (Expand search), depressed 26 (Expand search), depressed to (Expand search)
or decrease » of decrease (Expand search), not decrease (Expand search), to 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 AND decrease end processing ) OR ( decrease during depressed OR decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease AND decrease end processing ) OR ( decrease during depressed or decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease end processing ) OR ( decrease during depressed or decrease ))*.
