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 urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (Expand search)
urea decrease » the decrease (Expand search), or decrease (Expand search)
decrease std » decrease sod (Expand search), decrease and (Expand search), decrease at (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
std pattern » and pattern (Expand search), bud pattern (Expand search), old pattern (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 lesions decrease to decrease ) OR ( decrease urea decrease std pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease to decrease ) OR ( decrease urea decrease std pattern ))*.
