Perhaps you should try some spelling variations:
decrease field » decreases yield (Expand search), increase field (Expand search), decrease lipid (Expand search)
decrease cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (Expand search)
decreases and » decreases in (Expand search), decreases _ (Expand search)
field objects » fields objects (Expand search), field object (Expand search), field subjects (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » not decrease (Expand search), any decrease (Expand search), salt decreases (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 cell decrease akt decrease ) OR ( decreases AND decrease field objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease cell decrease akt decrease ) OR ( decreases and decrease field objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cell decrease akt decrease ) OR ( decreases and decrease field objects ))*.
