nick·el (Ni),

(nik'ĕl), Avoid the misspelling nickle.
A metallic bioelement, atomic no. 28, atomic wt. 58.6934, closely resembling cobalt and often associated with it. Protects ribosome structure against heat denaturation. A deficiency of nickel causes changes in the ultrastructure of the liver. It is a cofactor in various henzymes (for example, urease).

nickel

/nick·el/ (Ni) (nik´'l) a chemical element, at. no. 28. Long-term exposure to metallic nickel, as in jewelry, can cause contact (nickel) dermatitis; nickel fumes can be carcinogenic.

nickel (Ni)

Etymology: Ger, Kupfernickel, copper demon
a silver-white metallic element. Its atomic number is 28; its atomic mass is 58.71. Many people are allergic to nickel. Nickel causes more cases of allergic contact dermatitis than all other metals combined. Many cases occur from exposure to jewelry, coins, buckles, and snaps and from continued use of "carbonless" business forms. Nickel carbonyl, an extremely toxic volatile liquid, may produce serious lung damage if inhaled. Nickel is now a suspected carcinogen.

nickel

A metallic element (atomic number 28; atomic weight 58.69) that has been linked to deficiency states in some plants and animals. In some biological systems, nickel protects against heat-induced ribosomal damage; its role in humans is uncertain, but in excess it is toxic.
