Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease signal » increased signal (Expand search), decrease stigma (Expand search), decrease renal (Expand search)
disease lesions » disease lessons (Expand search), diseases lessons (Expand search)
decrease limb » decrease lipid (Expand search), decrease liver (Expand search), decrease in (Expand search)
limb decrease » will decrease (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 limb decrease signal processing ) OR ( disease lesions decrease of decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease limb decrease signal processing ) OR ( disease lesions decrease of decrease ))*.
