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 litter » increased litter (Expand search), decrease after (Expand search), decreases liver (Expand search)
litter decrease » faster decrease (Expand search), life decrease (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 and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and objects » and object (Expand search), and subjects (Expand search), and objectives (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 pro decrease ) OR ( decrease litter decrease AND objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions decrease pro decrease ) OR ( decrease litter decrease and objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease pro decrease ) OR ( decrease litter decrease and objects ))*.
