Perhaps you should try some spelling variations:
drugs decrease » drugs increases (Expand search), drugs release (Expand search)
release drugs » release drug (Expand search), releasing drugs (Expand search), release dates (Expand search)
decrease ocl » decreased bcl (Expand search), decreases oct (Expand search), decrease of (Expand search)
in release » ion release (Expand search), n release (Expand search), on release (Expand search)
ocl object » local object (Expand search), tool object (Expand search), social 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 in release drugs decrease ) OR ( decrease AND decrease ocl object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in release drugs decrease ) OR ( decrease AND decrease ocl object ))*.
