Perhaps you should try some spelling variations:
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
base processing » based processing (Expand search), waste processing (Expand search), laser processing (Expand search)
decreased base » decreased bone (Expand search), decreased brain (Expand search), decreased risk (Expand search)
decrease il » decreased il (Expand search), decrease in (Expand search), decrease hiv (Expand search)
il decrease » l decrease (Expand search), will decrease (Expand search), oil decreases (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease AND decreased base processing ) OR ( decrease response decrease il decrease ))~.
