Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease price » decrease pro (Expand search), decrease risk (Expand search)
price decrease » price increase (Expand search), juice decreases (Expand search), price increases (Expand search)
decrease pre » decrease pro (Expand search), decrease treg (Expand search), decrease the (Expand search)
pre step » more step (Expand search), one step (Expand search), the step (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 price decrease lesions decrease ) OR ( decrease NOT decrease pre step ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease price decrease lesions decrease ) OR ( decrease NOT decrease pre step ))*.
