Perhaps you should try some spelling variations:
decreases maturation » decrease migration (Expand search), decreases permeation (Expand search)
training decreases » training increases (Expand search)
decrease training » increased training (Expand search), disease training (Expand search), release training (Expand search)
decrease can » decrease in (Expand search), decrease at (Expand search), decrease on (Expand search)
can decrease » can increase (Expand search), to decrease (Expand search), the decrease (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)

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

• Removing quotes may allow a broader search: (( decrease training decreases maturation promoting ) OR ( decrease can decrease and decrease ))~.
