hua gene » human gene, a gene, hua ren
yang jin » yang jie, yang jun, ying jin
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yang ka » yang fan, yang yao
yang y » yang yi, yang _, yang 8

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

• Performing a fuzzy search may retrieve terms with similar spellings: dong ((yang y) or (yang ka)) hua gene yang jin ((hong ghi) OR (hong hai)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: dong ((yang y) OR (yang ka)) hua gene yang jin ((hong ghi) OR (hong hai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong ((yang y) or (yang ka)) hua gene yang jin ((hong ghi) OR (hong hai)) ;".
• Adding a wildcard symbol may retrieve word variants: dong ((yang y) or (yang ka)) hua gene yang jin ((hong ghi) OR (hong hai)) ;*.
