Perhaps you should try some spelling variations:
decrease rapidly » disease rapidly (Expand search), decrease lipid (Expand search)
rapidly decrease » rapid decrease (Expand search), rapidly increases (Expand search), rapidly increased (Expand search)
decrease plc » decrease il (Expand search), decrease pro (Expand search), decrease toc (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
plc based » hplc based (Expand search), c based (Expand search), arc based (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 AND decrease rapidly decrease ) OR ( decrease in decrease plc based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease rapidly decrease ) OR ( decrease in decrease plc based ))*.
