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 saga » decrease age (Expand search), decrease stigma (Expand search), decreases salt (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any decrease (Expand search)
saga pattern » usage pattern (Expand search), age pattern (Expand search), and pattern (Expand search)
decrease or » decrease of (Expand search), decrease on (Expand search), decrease pro (Expand search)
or decrease » not decrease (Expand search), to decrease (Expand search), _ decrease (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 akt decrease lesions decrease ) OR ( decrease OR decrease saga pattern ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease akt decrease lesions decrease ) OR ( decrease or decrease saga pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease akt decrease lesions decrease ) OR ( decrease or decrease saga pattern ))*.
