Perhaps you should try some spelling variations:
contact patterns » contrasting patterns (Expand search), intake patterns (Expand search)
decrease contact » decreased contact (Expand search), decreases contrast (Expand search), decreased content (Expand search)
decrease lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » not increase (Expand search), and decrease (Expand search), the decrease (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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease lipid decrease NOT decrease ) OR ( decrease to decrease contact patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lipid decrease not decrease ) OR ( decrease to decrease contact patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lipid decrease not decrease ) OR ( decrease to decrease contact patterns ))*.
