adhesion decrease » adhesin decreases (Expand search), lesions decrease (Expand search), abortion 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 to decrease adhesion decrease ) OR ( decrease OR decrease learning object ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease to decrease adhesion decrease ) OR ( decrease or decrease learning object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease adhesion decrease ) OR ( decrease or decrease learning object ))*.
