Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decrease field » decreases yield (Expand search), increase field (Expand search), decrease lipid (Expand search)
field pattern » yield pattern (Expand search), fixed pattern (Expand search), feed pattern (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any 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 response decrease NOT decrease ) OR ( decrease akt decrease field pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease response decrease NOT decrease ) OR ( decrease akt decrease field pattern ))*.
