their processing » the processing (Expand search), stir processing (Expand search), thermal processing (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (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 AND decrease their processing ) OR ( decrease urea decrease lesions decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease their processing ) OR ( decrease urea decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease their processing ) OR ( decrease urea decrease lesions decrease ))*.
