Perhaps you should try some spelling variations:
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
decrease anode » decrease and (Expand search), decrease income (Expand search), decreases and (Expand search)
decrease hiv » decrease in (Expand search), decrease their (Expand search), decreased high (Expand search)
hiv decrease » via decrease (Expand search), hiv increase (Expand search), will decrease (Expand search)
anode effect » diode effects (Expand search), acute effect (Expand search), age effect (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 hiv decrease to decrease ) OR ( decrease lesions decrease anode effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease hiv decrease to decrease ) OR ( decrease lesions decrease anode effect ))*.
