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)
decrease strain » increase strain (Expand search), decreases pain (Expand search), decreased brain (Expand search)
strain decrease » strains increases (Expand search), stress decreases (Expand search)
il processing » oil processing (Expand search), l processing (Expand search), mill processing (Expand search)
and decreased » and decreases (Expand search), and increased (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease strain decrease il processing ) OR ( decrease AND decreased lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease strain decrease il processing ) OR ( decrease and decreased lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease strain decrease il processing ) OR ( decrease and decreased lesions decrease ))*.
