Perhaps you should try some spelling variations:
mean decrease » a decrease (Expand Search)
nn decrease » _ decrease (Expand Search), a decrease (Expand Search), gy decreased (Expand Search)
ng decrease » _ decrease (Expand Search), a decrease (Expand Search), we decrease (Expand Search)
n decrease » _ decrease (Expand Search), a decrease (Expand Search), _ decreased (Expand Search)
100 ng » 100 mg (Expand Search), 100 nm (Expand Search), 100 ns (Expand Search)
50 n » 50 ns (Expand Search), 50 ng (Expand Search), 50 μ (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: "(((( 59 ((nn decrease) OR (mean decrease)) ) OR ( 100 ng decrease ))) OR ( 50 n decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( 59 ((nn decrease) OR (mean decrease)) ) OR ( 100 ng decrease ))) OR ( 50 n decrease ))*.
