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), disease during (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease the (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease with decrease during depressed ) OR ( decrease in decrease hiv objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease with decrease during depressed ) OR ( decrease in decrease hiv objects ))*.
