Talvez deva tentar algumas variações de ortografia:
activation enhances » activation mechanisms (Expandir a busca), activation mechanism (Expandir a busca)
enhances decrease » changes decrease (Expandir a busca), enhanced disease (Expandir a busca), enhanced release (Expandir a busca)
code activation » cone activation (Expandir a busca), clone activation (Expandir a busca), lobe activation (Expandir a busca)
python python » pythons python (Expandir a busca), piton python (Expandir a busca), pitons python (Expandir a busca)
code code » code cdc (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( code code activation enhances decrease ) OR ( _ python python python programming ))~.
