Perhaps you should try some spelling variations:
associated factors » associated bacteria
associate editors » associated pastors, associated operators, associated receptors
associated vector » associate director, associated secretory, associated infection
associate editor » associate director, associated factor, associated motor
associate factor » associate director, associated fatty

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: ((associate editor) OR (((((((associate factor) OR (associate editors))) OR (associated vector))) OR (associated factors)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((associate editor) or (((((((associate factor) OR (associate editors))) or (associated vector))) or (associated factors))))".
• Adding a wildcard symbol may retrieve word variants: ((associate editor) or (((((((associate factor) OR (associate editors))) or (associated vector))) or (associated factors))))*.
