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 lethal » decrease fetal (Expand search), decrease renal (Expand search), decrease total (Expand search)
lethal effect » lethal effects (Expand search), sublethal effects (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price decrease (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)

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 decrease pro decrease ) OR ( decrease akt decrease lethal effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease pro decrease ) OR ( decrease akt decrease lethal effect ))*.
