Talvez deva tentar algumas variações de ortografia:
increase suffering » increased buffering (Expandir a busca), decrease suffering (Expandir a busca), increase during (Expandir a busca)
suffering objects » suffering subjects (Expandir a busca)
decrease the » decreases the (Expandir a busca), decrease in (Expandir a busca), decrease of (Expandir a busca)
the decrease » to decrease (Expandir a busca), and decrease (Expandir a busca)
decrease hiv » decrease in (Expandir a busca), decrease their (Expandir a busca), decreased high (Expandir a busca)
hiv increase » diet increase (Expandir a busca), acid increase (Expandir a busca), and increase (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease the decrease AND decrease ) OR ( decrease hiv increase suffering objects ))~.
