human gene » human genome, human gender, human bone
long span » long han
long sin » dong sin, long run, long did
yang jin » yang jie, yang jun, ying jin
2 human » 3 human
yang yi » yang di, yang jui
yang xi » yang di, yang jui
hong g » hong ng, hong w, hong 7

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((long sin) OR (long span)) 2 human gene ((yang jin) or (((yang yi) or (yang xi)))) hong g ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((long sin) OR (long span)) 2 human gene ((yang jin) OR (((yang yi) OR (yang xi)))) hong g ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long sin) OR (long span)) 2 human gene ((yang jin) or (((yang yi) or (yang xi)))) hong g ;".
• Adding a wildcard symbol may retrieve word variants: ((long sin) OR (long span)) 2 human gene ((yang jin) or (((yang yi) or (yang xi)))) hong g ;*.
