the processing » the process (Expand search), image processing (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)

decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
decree that » decrees that (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 OR decrease the processing ) OR ( decrease il decree that decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease or decrease the processing ) OR ( decrease il decree that decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease or decrease the processing ) OR ( decrease il decree that decrease ))*.
