Perhaps you should try some spelling variations:
decrease lesion » decrease adhesion (Expand search), decrease asian (Expand search), decrease soon (Expand search)
lesion patterns » lesion pattern (Expand search), design patterns (Expand search), lesions pattern (Expand search)
decrease cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (Expand search)
decrease risk » decreased risk (Expand search), increase risk (Expand search), decrease in (Expand search)

at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (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 at decrease cell decrease ) OR ( decrease risk decrease lesion patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease at decrease cell decrease ) OR ( decrease risk decrease lesion patterns ))*.
