Perhaps you should try some spelling variations:
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease mask » decrease risk (Expand search), decrease milk (Expand search), decreased base (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)
decrease any » decrease and (Expand search), decreases and (Expand search), decreased and (Expand search)
any decrease » and decrease (Expand search), can decrease (Expand search), may decrease (Expand search)
mask object » mass objects (Expand search), dark object (Expand search), based object (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 NOT decrease any decrease ) OR ( decrease lipid decrease mask object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease any decrease ) OR ( decrease lipid decrease mask object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease any decrease ) OR ( decrease lipid decrease mask object ))*.
