Perhaps you should try some spelling variations:
burden decreases » burgers decreases (Expand search), brain decreases (Expand search), urea decreases (Expand search)
decrease burden » disease burden (Expand search), decrease further (Expand search)
decreases these » decreases the (Expand search), decreases th2 (Expand search), decreases pest (Expand search)
these processes » the processes (Expand search), thermal processes (Expand search), change processes (Expand search)
reaction using » prediction using (Expand search), detection using (Expand search), selection using (Expand search)
pectin python » piton python (Expand search)
using pectin » using peptide (Expand search), using petri (Expand search), using pet (Expand search)

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

• Removing quotes may allow a broader search: (( decrease burden decreases these processes ) OR ( reaction using pectin python programming ))~.
