lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease their » decrease the (Expand search), increase their (Expand search), decreases the (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 their decrease grain processing ) OR ( decrease cells decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease their decrease grain processing ) OR ( decrease cells decrease lesions decrease ))*.
