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)
decrease soil » decreases soil (Expand search), increase soil (Expand search), decrease il (Expand search)
soil decrease » oil decreases (Expand search), to decrease (Expand search), not decrease (Expand search)
decrease milk » decrease il (Expand search), decrease risk (Expand search), decrease in (Expand search)
decrease hiv » decrease in (Expand search), decrease their (Expand search), decreased high (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 soil decrease milk processing ) OR ( decrease lesions decrease hiv decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease soil decrease milk processing ) OR ( decrease lesions decrease hiv decrease ))*.
