hua gene » a gene, hua ren, hy5 gene
hua chen » jui chen, yu chen, a chen
yang jin » yang jie, yang jun, ying jin
hong shu » cong shu, tong shui, wong shiu
nan ya » nan yan, nana yaa

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

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