Perhaps you should try some spelling variations:
decreased lesions » decreased response (Expand search), decreased levels (Expand search), decreased neuron (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
cross decreased » causes decreased (Expand search), corn decreased (Expand search), loss decrease (Expand search)
decrease cross » decrease costs (Expand search), increase cross (Expand search), decrease sucrose (Expand search)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may 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 any decrease AND processing ) OR ( decrease cross decreased lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease any decrease AND processing ) OR ( decrease cross decreased lesions decrease ))*.
