Perhaps you should try some spelling variations:
training decreases » training increases (Expand search)
decrease training » increased training (Expand search), disease training (Expand search), release training (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
income objects » income effects (Expand search), home objects (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 lesions decrease training decreases ) OR ( decrease _ decrease income objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease training decreases ) OR ( decrease _ decrease income objects ))*.
