Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease std » decrease sod (Expand search), decrease and (Expand search), decrease at (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
std objects » and objects (Expand search), 3d objects (Expand search), old objects (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease in decrease lesions decrease ) OR ( decrease faster decrease std objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease lesions decrease ) OR ( decrease faster decrease std objects ))*.
