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)
flow processing » flour processing (Expand search), flow process (Expand search), flow processes (Expand search)
decrease flow » decreases flow (Expand search), decrease low (Expand search), decrease food (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and 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 litter decrease flow processing ) OR ( decrease NOT decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease litter decrease flow processing ) OR ( decrease not decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease litter decrease flow processing ) OR ( decrease not decrease lesions decrease ))*.
