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