Perhaps you should try some spelling variations:
decrease within » decrease with (Expand search), decreases with (Expand search), disease within (Expand search)
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
within objects » within subjects (Expand search), with objects (Expand search), without objects (Expand search)
decrease food » decreases food (Expand search), increase food (Expand search), decreases blood (Expand search)
food decrease » food decreases (Expand search), foods decreases (Expand search), flow decrease (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lipid decrease food decrease ) OR ( decrease AND decrease within objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lipid decrease food decrease ) OR ( decrease AND decrease within objects ))*.
