Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease walking » increase walking (Expand search), decrease during (Expand search), decrease lodging (Expand search)
walking process » making process (Expand search), working process (Expand search), baking process (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)
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 NOT decrease walking process ) OR ( decrease lesions case toc decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease walking process ) OR ( decrease lesions case toc decrease ))*.
