yang yang » wang yan
yang july » yang judy, yang jui, yang jun
gene bank » gene banks, one bank
young ghi » young choi, hong ghi, young hr

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: wang yang yang july ((gene bank) OR (genomen bank)) jae ((young ghi) OR (young get)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang july ((gene bank) or (genomen bank)) jae ((young ghi) OR (young get)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang july ((gene bank) or (genomen bank)) jae ((young ghi) OR (young get)) ;*.
