Perhaps you should try some spelling variations:
modulation decrease » maturation decreases (Expand search), mutation decreases (Expand search), stimulation decreases (Expand search)
disease modulation » disease population (Expand search), disease populations (Expand search), disease duration (Expand search)
decrease yield » decreases yield (Expand search), increase yield (Expand search), increases yield (Expand search)
decrease pain » decreases pain (Expand search), decrease in (Expand search), decreased brain (Expand search)
yield pattern » yield after (Expand search), yield water (Expand search), yield protein (Expand search)

decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (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 pain disease modulation decrease ) OR ( decrease NOT decrease yield pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease pain disease modulation decrease ) OR ( decrease not decrease yield pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pain disease modulation decrease ) OR ( decrease not decrease yield pattern ))*.
