Perhaps you should try some spelling variations:
decrease pulmonary » decreases pulmonary (Expand search), increased pulmonary (Expand search), increases pulmonary (Expand search)
pulmonary proteins » pulmonary patterns (Expand search), pulmonary prosthesis (Expand search), pulmonary veins (Expand search)
decrease rapidly » disease rapidly (Expand search), decrease lipid (Expand search)
rapidly decrease » rapid decrease (Expand search), rapid increase (Expand search), taping decrease (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (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 NOT decrease pulmonary proteins ) OR ( decrease _ decrease rapidly decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease pulmonary proteins ) OR ( decrease _ decrease rapidly decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease pulmonary proteins ) OR ( decrease _ decrease rapidly decrease ))*.
