Perhaps you should try some spelling variations:
decrease pulmonary » decreases pulmonary (Expand search), increased pulmonary (Expand search), increases pulmonary (Expand search)
pulmonary objects » pulmonary effects (Expand search), pulmonary spect (Expand search), primary objects (Expand search)
decrease will » decrease with (Expand search), decrease cell (Expand search), decrease il (Expand search)
decrease may » decrease at (Expand search), decrease by (Expand search), decrease human (Expand search)
may decrease » may increase (Expand search), can decrease (Expand search), to decrease (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (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 may decrease will decrease ) OR ( decrease of decrease pulmonary objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease may decrease will decrease ) OR ( decrease of decrease pulmonary objects ))*.
