Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
and processing » food processing (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (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 burden decrease AND processing ) OR ( decrease AND decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease burden decrease and processing ) OR ( decrease AND decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease burden decrease and processing ) OR ( decrease AND decrease lesions decrease ))*.
