Perhaps you should try some spelling variations:
decreases processes » decrease processes (Expand search)
disease decreases » disease increased (Expand search), disease cases (Expand search), disease disease (Expand search)
function role » functional role (Expand search), functional roles (Expand search), dysfunction role (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
pitons » citons (Expand search), pitoni (Expand search), pitoes (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 disease decreases processes ) OR ( function role pitons python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and disease decreases processes ) OR ( function role pitons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and disease decreases processes ) OR ( function role pitons python programming ))*.
