Perhaps you should try some spelling variations:
deceased lesions » depressed lesions (Expand search), disease lesions (Expand search), ulcerated lesions (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
at processing » meat processing (Expand search), heat processing (Expand search), wet processing (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with deceased » with decreased (Expand search), with increased (Expand search), with disease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (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 NOT decrease at processing ) OR ( decrease with deceased lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease at processing ) OR ( decrease with deceased lesions decrease ))*.
