Perhaps you should try some spelling variations:
defense processes » defense process (Expand search), decrease processes (Expand search), disease processes (Expand search)
decrease defense » defense defense (Expand search), decrease release (Expand search), decreases disease (Expand search)
reaction using » prediction using (Expand search), detection using (Expand search), selection using (Expand search)
using pitons » using pion (Expand search), using pivots (Expand search), using mertons (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• Removing quotes may allow a broader search: (( decrease to decrease defense processes ) OR ( reaction using pitons python programming ))~.
