Talvez deva tentar algumas variações de ortografia:
dysfunction system » dysfunction systematic (Expandir a busca), dysfunction symptoms (Expandir a busca), dysfunction after (Expandir a busca)
code dysfunction » node dysfunction (Expandir a busca), cord dysfunction (Expandir a busca), lobe dysfunction (Expandir a busca)
system decrease » system decreases (Expandir a busca), system increase (Expandir a busca), symptom decrease (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 dysfunction system decrease ) OR ( _ python python python programming ))~.
