Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions case » lesion case (Expand search), lesions caused (Expand search), lesions based (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not decrease (Expand search)
decrease std » decrease sod (Expand search), decrease and (Expand search), decrease at (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
std object » and object (Expand search), 3d object (Expand search), ood object (Expand search)
case toc » case to (Expand search), casa toc (Expand search), case tool (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 case toc decrease ) OR ( decrease in decrease std object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions case toc decrease ) OR ( decrease in decrease std object ))*.
