Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
response defense » response decrease (Expand search), resource defense (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (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 the decrease _ processor ) OR ( decrease response defense AND decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease the decrease _ processor ) OR ( decrease response defense and decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease the decrease _ processor ) OR ( decrease response defense and decrease ))*.
