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 cells » decrease cell (Expand search), decreases cell (Expand search), decrease costs (Expand search)
cells decrease » cells decreases (Expand search), cells increase (Expand search), cells increases (Expand search)
decrease multi » decrease milk (Expand search), decrease quality (Expand search)
multi process » multi access (Expand search), multi project (Expand search), multi probe (Expand search)
decrease help » decrease cell (Expand search), decrease their (Expand search), decrease the (Expand search)
help decrease » help increase (Expand search), the decrease (Expand search), term 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 cells decrease multi process ) OR ( decrease help decrease lesions decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease cells decrease multi process ) OR ( decrease help decrease lesions decrease ))*.
