Perhaps you should try some spelling variations:
decrease methods » defense methods (Expand search), disease methods (Expand search), dense methods (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease ligand » decrease lipid (Expand search), decrease lodging (Expand search), decrease oxidant (Expand search)
ligand decrease » ligand release (Expand search), ligands increased (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
affect » affected (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 AND decrease faster decrease ) OR ( decrease ligand decrease methods affect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease faster decrease ) OR ( decrease ligand decrease methods affect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease faster decrease ) OR ( decrease ligand decrease methods affect ))*.
