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 burden » disease burden (Expand search), decrease further (Expand search)
burden process » burning process (Expand search), green process (Expand search), maden process (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » or decrease (Expand search), price decrease (Expand search), term decrease (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 lesions decrease burden process ) OR ( decrease to decrease pro decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease burden process ) OR ( decrease to decrease pro decrease ))*.
