Talvez deva tentar algumas variações de ortografia:
decrease buffering » decrease suffering (Expandir a busca), increased buffering (Expandir a busca), decrease during (Expandir a busca)
buffering effect » buffer effect (Expandir a busca), lowering effect (Expandir a busca)
decrease hiv » decrease in (Expandir a busca), decrease their (Expandir a busca), decreased high (Expandir a busca)
hiv decrease » via decrease (Expandir a busca), hiv increase (Expandir a busca), will decrease (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)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease hiv decrease AND decrease ) OR ( decrease the decrease buffering effect ))~.
