processes effect » processes effects (Expand search), processes affect (Expand search), process effect (Expand search)
decrease stent » decreased pten (Expand search), decrease std (Expand search), decrease soon (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 stent decrease ) OR ( decrease that decrease processes effect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease stent decrease ) OR ( decrease that decrease processes effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease stent decrease ) OR ( decrease that decrease processes effect ))*.
