Talvez deva tentar algumas variações de ortografia:
lesions decrease » response decrease (Expandir a busca), lesions case (Expandir a busca)
disease lesions » disease lessons (Expandir a busca), diseases lessons (Expandir a busca)
risk processor » risc processor (Expandir a busca), risk processo (Expandir a busca), risk process (Expandir a busca)
decrease risk » decreased risk (Expandir a busca), increase risk (Expandir a busca), decrease hiv (Expandir a busca)
in disease » skin diseases (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease NOT decrease risk processor ) OR ( decrease in disease lesions decrease ))~.
