Perhaps you should try some spelling variations:
heart processing » heat processing (Expand search), meat processing (Expand search), fear processing (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
costs decreased » cross decreased (Expand search), causes decreased (Expand search), not decreased (Expand search)
decreased heart » decreased health (Expand search), decreased fear (Expand search), decreased left (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (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 costs decreased heart processing ) OR ( decrease _ decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease costs decreased heart processing ) OR ( decrease _ decrease lesions decrease ))*.
