Perhaps you should try some spelling variations:
decrease gdl » decrease il (Expand search), decrease model (Expand search), decrease cell (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
gdl object » ocl object (Expand search), model object (Expand search), legal object (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 at decrease _ decrease ) OR ( decrease in decrease gdl object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decrease _ decrease ) OR ( decrease in decrease gdl object ))*.
