Talvez deva tentar algumas variações de ortografia:
decrease during » increase during (Expandir a busca), increases during (Expandir a busca), increased during (Expandir a busca)
during decrease » during increased (Expandir a busca), during depressed (Expandir a busca), during disease (Expandir a busca)
increase active » increases reactive (Expandir a busca), increased reactive (Expandir a busca), increase bioactive (Expandir a busca)
active subjects » active subject (Expandir a busca)
decrease of » decrease in (Expandir a busca)
of increase » of increased (Expandir a busca), an increase (Expandir a busca), of increasing (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease NOT decrease during decrease ) OR ( decrease of increase active subjects ))~.
