Perhaps you should try some spelling variations:
pulmonary abscesses » pulmonary abscess (Expand search), pulmonary diseases (Expand search), pulmonary assessments (Expand search)
decrease pulmonary » decreases pulmonary (Expand search), increased pulmonary (Expand search), disease pulmonary (Expand search)
decrease decrease » decrease release (Expand search), disease decreases (Expand search), decreases disease (Expand search)
decrease after » increase after (Expand search), disease after (Expand search)
decrease will » decrease cell (Expand search), decrease with (Expand search), decrease il (Expand search)
decrease not » decrease of (Expand search), decrease at (Expand search), decrease akt (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 will decrease pulmonary abscesses ) OR ( decrease NOT decrease decrease after ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease will decrease pulmonary abscesses ) OR ( decrease not decrease decrease after ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease will decrease pulmonary abscesses ) OR ( decrease not decrease decrease after ))*.
