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 cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (Expand search)
decrease ctac » decrease toc (Expand search), decrease fetal (Expand search), decrease total (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 cell decrease _ decrease ) OR ( decrease lesions decrease ctac effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cell decrease _ decrease ) OR ( decrease lesions decrease ctac effect ))*.
