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)
pear processing » fear processing (Expand search), peach processing (Expand search), poir processing (Expand search)
decrease pear » decrease fear (Expand search), decreased fear (Expand search), decreased heart (Expand search)
decrease loss » decrease costs (Expand search), decrease low (Expand search), decrease blood (Expand search)
loss decrease » loss decreases (Expand search), to decrease (Expand search), not decrease (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 pear processing ) OR ( decrease AND decrease loss decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease pear processing ) OR ( decrease AND decrease loss decrease ))*.
