Perhaps you should try some spelling variations:
decrease yield » decreases yield (Expand search), increase yield (Expand search), increases yield (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), and decrease (Expand search)
yield pattern » yield after (Expand search), yield water (Expand search), yield protein (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)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 rate decrease to decrease ) OR ( decrease akt decrease yield pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease to decrease ) OR ( decrease akt decrease yield pattern ))*.
