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 their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (Expand search)
urea decrease » the decrease (Expand search), or decrease (Expand search)
their objects » the objects (Expand search), their objectives (Expand search), their projects (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 urea decrease lesions decrease ) OR ( decrease NOT decrease their objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease urea decrease lesions decrease ) OR ( decrease NOT decrease their objects ))*.
