Perhaps you should try some spelling variations:
rats decreases » and decreases (Expand search), but decreases (Expand search), stress decreases (Expand search)
decrease rats » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
and decrease » and decreases (Expand search), and decreased (Expand search), and increase (Expand search)
decrease akt » decrease at (Expand search), decrease after (Expand search), decrease with (Expand search)
akt decrease » not decrease (Expand search), any decrease (Expand search), salt decreases (Expand search)
decreases 3d » decreases and (Expand search), decreases ldl (Expand search), decreases in (Expand search)
3d objects » 3d object (Expand search), and objects (Expand search), _ objects (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 AND decrease akt decrease ) OR ( decrease rats decreases 3d objects ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decrease akt decrease ) OR ( decrease rats decreases 3d objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decrease akt decrease ) OR ( decrease rats decreases 3d objects ))*.
