Perhaps you should try some spelling variations:
nn decrease » _ decrease (Expand Search), a decrease (Expand Search), mean decrease (Expand Search)
ns decrease » _ decrease (Expand Search), a decrease (Expand Search), use decreased (Expand Search)
we decrease » _ decrease (Expand Search), a decrease (Expand Search), mean decrease (Expand Search)
ng decrease » _ decrease (Expand Search), a decrease (Expand Search), gy decreased (Expand Search)
50 nn » 50 ns (Expand Search), 50 ng (Expand Search), 50 n (Expand Search)
10 ng » 100 ng (Expand Search), 10 mg (Expand Search), 10 nm (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: "(( 50 nn decrease ) OR ((( 50 ((ns decrease) OR (we decrease)) ) OR ( 10 ng decrease ))))~".
• Adding a wildcard symbol may retrieve word variants: (( 50 nn decrease ) OR ((( 50 ((ns decrease) OR (we decrease)) ) OR ( 10 ng decrease ))))*.
