Perhaps you should try some spelling variations:
nn decrease » mean decrease (Expand Search), gy decreased (Expand Search), b1 decreased (Expand Search)
ng decrease » we decrease (Expand Search), gy decreased (Expand Search), b1 decreased (Expand Search)
_ decrease » _ decreased (Expand Search)
a decrease » _ decreased (Expand Search), _ decreases (Expand Search)
10 ng » 100 ng (Expand Search), 10 mg (Expand Search), 10 nm (Expand Search)
50 a » 50 μ (Expand Search), 50 _ (Expand Search), 50 c (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 (_ decrease)) ) OR ( 10 ng decrease ))) OR ( 50 a decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( 59 ((nn decrease) OR (_ decrease)) ) OR ( 10 ng decrease ))) OR ( 50 a decrease ))*.
