Perhaps you should try some spelling variations:
decrease buffer » decrease after (Expand search), decrease burden (Expand search), decrease suffering (Expand search)
decreases bone » decreased bone (Expand search), increases bone (Expand search), decreases blood (Expand search)
buffer objects » buffer effects (Expand search)
bone decrease » on decrease (Expand search), ozone decreases (Expand search), gene decreases (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreases bone decrease AND decrease ) OR ( decrease at decrease buffer objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreases bone decrease AND decrease ) OR ( decrease at decrease buffer objects ))*.
