Perhaps you should try some spelling variations:
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (Expand search)
their decrease » the decrease (Expand search), their disease (Expand search), the decreased (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with paternal » with maternal (Expand search), with external (Expand search), with internal (Expand search)
decrease pro » decrease or (Expand search), decrease food (Expand search), decrease treg (Expand search)
pro decrease » to decrease (Expand search), or decrease (Expand search), price decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (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 pro decrease their decrease ) OR ( decrease NOT decrease with paternal ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease pro decrease their decrease ) OR ( decrease not decrease with paternal ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease pro decrease their decrease ) OR ( decrease not decrease with paternal ))*.
