Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
unit processing » nut processing (Expand search), fruit processing (Expand search), input processing (Expand search)
decrease burden » disease burden (Expand search), decrease further (Expand search)
burden decrease » burden disease (Expand search), urea decrease (Expand search), burgers decreases (Expand search)
decrease unit » decrease and (Expand search), decrease with (Expand search), decrease akt (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (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 decrease unit processing ) OR ( decrease burden decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease in decrease unit processing ) OR ( decrease burden decrease lesions decrease ))*.
