Perhaps you should try some spelling variations:
rate decreases » rats decreases (Expand search), rate decrease (Expand search), water decreases (Expand search)
decreases high » decreased high (Expand search), decrease high (Expand search), decreases hip (Expand search)
decrease urea » decrease treg (Expand search), decrease burden (Expand search), decreases areas (Expand search)
urea decrease » urea increases (Expand search), the decrease (Expand search), or decrease (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
high titer » high water (Expand search), high tide (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: "(( decrease _ decrease urea decrease ) OR ( decrease rate decreases high titer ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease _ decrease urea decrease ) OR ( decrease rate decreases high titer ))*.
