yan change » can change, man changed, than change
gene yang » gene bank
shang kai » shang hai
yang min » yang mind, yang jin, tang min
hong hai » shang hai, zhong tai, dang hai
a gene » a genre, a gender, a gentle
wang » wing, wan, lang

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

• Performing a fuzzy search may retrieve terms with similar spellings: wang ((yan change) OR (mean change)) a gene yang min ((hong hai) or (shang kai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan change) OR (mean change)) a gene yang min ((hong hai) OR (shang kai)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan change) OR (mean change)) a gene yang min ((hong hai) or (shang kai)) ;*".
