Perhaps you should try some spelling variations:
depressed visual » decreased visual (Expand search), expressao visual (Expand search), estresse visual (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)
decrease treg » decrease the (Expand search), increase treg (Expand search), decrease their (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs 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 treg decrease ) OR ( decrease during depressed visual object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease treg decrease ) OR ( decrease during depressed visual object ))*.
