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)
toc decreases » c decreases (Expand search), oic decreases (Expand search), co2 decreases (Expand search)
decrease treg » decrease the (Expand search), increase treg (Expand search), decrease their (Expand search)
treg decrease » the decrease (Expand search), urea decrease (Expand search), drugs decrease (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
decrease to » decreased to (Expand search), decrease the (Expand search), decrease pro (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 toc decreases yield processor ) OR ( decrease treg decrease to decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease toc decreases yield processor ) OR ( decrease treg decrease to decrease ))*.
