Perhaps you should try some spelling variations:
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid objects » rigid objects (Expand search), typed objects (Expand search), field objects (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)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease can » decrease in (Expand search), decrease and (Expand search), decrease at (Expand search)
can decrease » and decrease (Expand search), can increase (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 hiv decrease the decrease ) OR ( decrease can decrease lipid objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease hiv decrease the decrease ) OR ( decrease can decrease lipid objects ))*.
