Perhaps you should try some spelling variations:
decrease leaming » decreases weaning (Expand search), decreases healing (Expand search), decrease lodging (Expand search)
leaming objects » learning objects (Expand search), naming objects (Expand search), teaching objects (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)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
rate decrease » rats decreases (Expand search), rate increase (Expand search), to 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 rate decrease OR decrease ) OR ( decrease lipid decrease leaming objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rate decrease OR decrease ) OR ( decrease lipid decrease leaming objects ))*.
