hua gene » human gene, a gene, hua ren
yang jin » yang jie, yang jun, ying jin

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((yang yang) or (wang yong)) yi hua gene yang jin ((hong g) OR (hong w)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((yang yang) OR (wang yong)) yi hua gene yang jin ((hong g) OR (hong w)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yang yang) or (wang yong)) yi hua gene yang jin ((hong g) OR (hong w)) ;*".
