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)
decreased brain » decreases brain (Expand search), increased brain (Expand search), decreased in (Expand search)
brain decrease » brain decreases (Expand search), brazil decrease (Expand search), strain decrease (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (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: "(( decreased brain decrease il decrease ) OR ( decrease NOT decrease pulmonary objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased brain decrease il decrease ) OR ( decrease NOT decrease pulmonary objects ))*.
