Talvez debería tentar con algunhas variantes ortográficas:
microarray profiling » microrna profiling
information let » information leg, information leak, information list
two dimensional » three dimensional
array formulas » area formulas, harrop formulas, array format
array string » array strong, arrays strings, array sharing
let two » set two, last two, next two

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: information let two dimensional ((((microarray profiling) OR (array formulas))) OR (array string))~.
• Adding a wildcard symbol may retrieve word variants: information let two dimensional ((((microarray profiling) or (array formulas))) or (array string))*.
