Perhaps you should try some spelling variations:
depressed buffer » depressed older (Expand search), depressed mother (Expand search)
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)
buffer effect » buffering effect (Expand search), border effect (Expand search), under effect (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease in (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price decrease (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 NOT decrease pro decrease ) OR ( decrease during depressed buffer effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease pro decrease ) OR ( decrease during depressed buffer effect ))*.
