• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease its decrease ligand decrease ) OR ( decrease or decrease iron affects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease its decrease ligand decrease ) OR ( decrease or decrease iron affects ))*.
