Talvez deva tentar algumas variações de ortografia:
decreased stigma » decrease stigma (Expandir a busca), decreased time (Expandir a busca), decreased plasma (Expandir a busca)
stigma processes » estigma processos (Expandir a busca), sti processes (Expandir a busca), stigma crosses (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
on decreased » in decreased (Expandir a busca), of decreased (Expandir a busca), on deceased (Expandir a busca)
decrease on » decrease in (Expandir a busca), decrease of (Expandir a busca), decrease or (Expandir a busca)
data python » gate python (Expandir a busca), dado python (Expandir a busca), dados python (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease on decreased stigma processes ) OR ( python data python python programming ))~.
