Perhaps you should try some spelling variations:
decrease rapid » decrease lipid (Expand search), decreased ratio (Expand search), decrease and (Expand search)
rats decreases » and decreases (Expand search), but decreases (Expand search), stress decreases (Expand search)
rapid decrease » rapidly decrease (Expand search), rapid increase (Expand search), ratio decrease (Expand search)
decrease typed » decrease the (Expand search), decrease lipid (Expand search), decrease treg (Expand search)
decrease rats » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
decreases not » decreases post (Expand search), decreases of (Expand search), decreases low (Expand search)
typed objects » naked objects (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 rats decreases NOT decrease ) OR ( decrease rapid decrease typed objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease rats decreases not decrease ) OR ( decrease rapid decrease typed objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rats decreases not decrease ) OR ( decrease rapid decrease typed objects ))*.
