Perhaps you should try some spelling variations:
decrease overtime » decrease overall (Expand search)
overtime process » colective process (Expand search), time process (Expand search), average process (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)
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 of decrease overtime process ) OR ( decrease lesions decrease _ decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease of decrease overtime process ) OR ( decrease lesions decrease _ decrease ))*.
