Perhaps you should try some spelling variations:
coupled processes » coupling processes (Expand search), combined processes (Expand search), controlled processes (Expand search)
disease coupled » disease complex (Expand search), disease could (Expand search), disease compared (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
python 2a » python _ (Expand search), python c (Expand search), python to (Expand search)
2a pitons » _ pitons (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 coupled processes ) OR ( python 2a pitons python programming ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and disease coupled processes ) OR ( python 2a pitons python programming ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and disease coupled processes ) OR ( python 2a pitons python programming ))*.
