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 during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
during decrease » during increased (Expand search), during depressed (Expand search), during disease (Expand search)
decrease pso » decrease pro (Expand search), decrease sod (Expand search), decrease food (Expand search)
pso based » bio based (Expand search), zno based (Expand search), co based (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 NOT decrease lesions decrease ) OR ( decrease during decrease pso based ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease NOT decrease lesions decrease ) OR ( decrease during decrease pso based ))*.
