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)
decrease not » decrease of (Expand search), decrease at (Expand search), decrease on (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), any decrease (Expand search), salt decreases (Expand search)
decrease low » decreases low (Expand search), decreases flow (Expand search), decrease of (Expand search)
low objects » how objects (Expand search), wow objects (Expand search), new objects (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 lesions decrease NOT decrease ) OR ( decrease akt decrease low objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease not decrease ) OR ( decrease akt decrease low objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease not decrease ) OR ( decrease akt decrease low objects ))*.
