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)
decreases blood » increases blood (Expand search)
blood objects » cloud objects (Expand search), beyond objects (Expand search), blood infects (Expand search)
to decreases » to decrease (Expand search), to decreased (Expand search), co2 decreases (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 _ decrease lesions decrease ) OR ( decrease to decreases blood objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease lesions decrease ) OR ( decrease to decreases blood objects ))*.
