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 falling » decrease walking (Expand search), decrease following (Expand search), decreases handling (Expand search)
falling objects » flying objects (Expand search), talking objects (Expand search), telling objects (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to 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 AND decrease of decrease ) OR ( decrease lesions decrease falling objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease of decrease ) OR ( decrease lesions decrease falling objects ))*.
