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 problem » release problem (Expand search), disease problem (Expand search), decrease pro (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (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 faster decrease NOT decrease ) OR ( decrease lesions decrease problem AND ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease faster decrease NOT decrease ) OR ( decrease lesions decrease problem AND ))*.
