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