Perhaps you should try some spelling variations:
decreases flying » decreases lung (Expand search), decreases during (Expand search), decreases along (Expand search)
stress decreases » stress increases (Expand search)
decrease stress » decreases stress (Expand search), increase stress (Expand search), decrease treg (Expand search)
flying objects » moving objects (Expand search), flying insects (Expand search)
decrease with » decreases with (Expand search), increase with (Expand search), decrease in (Expand search)
with decrease » with decreased (Expand search), with deceased (Expand search), with increase (Expand search)
decrease akt » decrease at (Expand search), decrease and (Expand search), decrease after (Expand search)
akt decrease » and decrease (Expand search), not decrease (Expand search), any 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 with decrease akt decrease ) OR ( decrease stress decreases flying objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease with decrease akt decrease ) OR ( decrease stress decreases flying objects ))*.
