Talvez deva tentar algumas variações de ortografia:
decreased disease » decreases disease (Expandir a busca), increased disease (Expandir a busca), decreased base (Expandir a busca)
disease processes » disease process (Expandir a busca), disease progress (Expandir a busca), these processes (Expandir a busca)
testing program » testing programs (Expandir a busca), teaching program (Expandir a busca), visiting program (Expandir a busca)
of decreased » of deceased (Expandir a busca), of decrease (Expandir a busca), of increased (Expandir a busca)
decrease of » decrease in (Expandir a busca)
an testing » adn testing (Expandir a busca), on testing (Expandir a busca), in testing (Expandir a busca)
code an » code and (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease of decreased disease processes ) OR ( python code an testing program ))~.
