Perhaps you should try some spelling variations:
human gene » human genome, human gender, human bone
wang yong » wang yang, wang hyoung, wang yan
yong yang » yang yang, dong yang, ying yang
chang min » zhang ming, chang mae, chan ming
sang minh » kang minah, anh minh, song min
hua gene » a gene, hua ren, hy5 gene
hong g » hong ng, hong w, hong 7

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 yong yang ((hua gene) OR (human gene)) ((chang min) OR (sang minh)) hong g ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong yang ((hua gene) OR (human gene)) ((chang min) or (sang minh)) hong g ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong yang ((hua gene) OR (human gene)) ((chang min) or (sang minh)) hong g ;*.
