Perhaps you should try some spelling variations:
decreases yield » increases yield (Expand search), decreases cell (Expand search), decreases il (Expand search)
yield processor » field processor (Expand search), field professor (Expand search), speed processor (Expand search)
not decreases » not decrease (Expand search), not decreased (Expand search), nfoh decreases (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
life decrease » life decreases (Expand search), life decreased (Expand search), life increase (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (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 NOT decreases yield processor ) OR ( decrease life decrease with decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decreases yield processor ) OR ( decrease life decrease with decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decreases yield processor ) OR ( decrease life decrease with decrease ))*.
