Talvez deva tentar algumas variações de ortografia:
decrease lipid » increases lipid (Expandir a busca), increased lipid (Expandir a busca)
lipid decrease » rapid decrease (Expandir a busca), ligand decrease (Expandir a busca), limb decrease (Expandir a busca)
decrease fetal » decrease fear (Expandir a busca), decrease renal (Expandir a busca), decrease total (Expandir a busca)
fetal objects » metal objects (Expandir a busca), real objects (Expandir a busca), focal objects (Expandir a busca)
in decrease » in decreased (Expandir a busca), on decrease (Expandir a busca), pain decrease (Expandir a busca)

Você pode obter mais resultados ajustando o argumento de busca.

• Remover as aspas pode possibilitar buscas mais amplas: (( decrease lipid decrease in decrease ) OR ( decrease NOT decrease fetal objects ))~.
