Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
in connectivity » and connectivity (Expand search), air connectivity (Expand search), of connectivity (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)
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.

• Removing quotes may allow a broader search: (( decrease response decrease akt decrease ) OR ( decrease of decrease in connectivity ))~.
