Perhaps you should try some spelling variations:
life decrease » life decreases (Expand search), life decreased (Expand search), life increase (Expand search)
decrease life » decrease liver (Expand search), increase life (Expand search), decreases liver (Expand search)
decrease yiel » decreases yield (Expand search), decrease il (Expand search), increase yield (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » not increase (Expand search), and decrease (Expand search), the decrease (Expand search)
yiel pattern » yield pattern (Expand search), diel pattern (Expand search), diel patterns (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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease NOT decrease to decrease ) OR ( decrease life decrease yiel pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease to decrease ) OR ( decrease life decrease yiel pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease to decrease ) OR ( decrease life decrease yiel pattern ))*.
