Perhaps you should try some spelling variations:
during depressed » during depressive (Expand search), during repressive (Expand search), feeling depressed (Expand search)
decrease bonding » increase bonding (Expand search), decrease flooding (Expand search), decrease lodging (Expand search)
bonding protocol » bonding protocols (Expand search), loading protocol (Expand search), loading protocols (Expand search)
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (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 OR decrease during depressed ) OR ( decrease AND decrease bonding protocol ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease during depressed ) OR ( decrease and decrease bonding protocol ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease during depressed ) OR ( decrease and decrease bonding protocol ))*.
