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 to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)
decrease uv » decrease hiv (Expand search), decrease due (Expand search), decrease in (Expand search)
uv patterns » and patterns (Expand search), age patterns (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 NOT decrease uv patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease to decrease ) OR ( decrease NOT decrease uv patterns ))*.
