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 urinary » increased urinary (Expand search), decrease pulmonary (Expand search), decrease during (Expand search)
urinary object » primary object (Expand search), ordinary objects (Expand search), primary objects (Expand search)
decrease fear » decreased fear (Expand search), decrease fetal (Expand search), decreased heart (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 fear decrease lesions decrease ) OR ( decrease at decrease urinary object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease fear decrease lesions decrease ) OR ( decrease at decrease urinary object ))*.
