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)
decrease buffer » decrease after (Expand search), decrease burden (Expand search), decrease suffering (Expand search)
buffer effects » buffer effect (Expand search), burger effects (Expand search), after effects (Expand search)
depressed il » depressed i (Expand search), repressed in (Expand search), depressed nk (Expand search)
il decrease » l decrease (Expand search), will decrease (Expand search), oil decreases (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 during depressed il decrease ) OR ( decrease AND decrease buffer effects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease during depressed il decrease ) OR ( decrease AND decrease buffer effects ))*.
