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