Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » strains increases (Expand search), stress decreases (Expand search)
decrease yield » decreases yield (Expand search), increase yield (Expand search), increases yield (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)
yield water » yield after (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 akt decrease ) OR ( decrease strain decrease yield water ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease response decrease akt decrease ) OR ( decrease strain decrease yield water ))*.
