What's the difference between neogen and nickel?

Neogen


Definition:

  • (n.) An alloy resembling silver, and consisting chiefly of copper, zinc, and nickel, with small proportions of tin, aluminium, and bismuth.

  • (11) All three enzymes had negligible activity in the neogenic zone and mesenchyme.

Nickel


Definition:

  • (n.) A bright silver-white metallic element. It is of the iron group, and is hard, malleable, and ductile. It occurs combined with sulphur in millerite, with arsenic in the mineral niccolite, and with arsenic and sulphur in nickel glance. Symbol Ni. Atomic weight 58.6.
  • (n.) A small coin made of or containing nickel; esp., a five-cent piece.

Example Sentences:

  • (1) The effect of airborne pollution, especially nickel, from Kola has been studied in 10,612 persons who participated in a cardiovascular screening survey in Finnmark in 1974-75.
  • (2) In order to determine the specific action of cadmium on bone metabolism, the effect of cadmium on alkaline phosphatase activity, a marker enzyme of osteoblasts, was compared with that of other divalent heavy metal ions, i.e., zinc, manganese, lead, copper, nickel and mercury (10 microM each), using cloned osteoblast-like cells, MC3T3-E1.
  • (3) You could understand why the Met was frantic to find who had stabbed Rachel Nickell 49 times on Wimbledon Common while her screaming child looked on, but the case against Stagg was preposterous.

  • (5) Nickel induced considerable increases in both glucose and glucagon levels, delayed in 19-day pregnant rats with respect to controls, and deep and permanent decreases in glycogen and amino acids in pregnant rats.

  • (7) These results suggest that nickel is unable to induce basepair or frameshift mutations in Salmonella tester strains and are discussed in relationship to the low binding affinity of Ni(II) for DNA.
  • (8) Titanium-nickel alloy composed of 50% by weight of each metal has unique thermal shape-memory properties, with a transition temperature of 20 degrees C. Each stent consists of one wire with a diameter of 0.9 mm.
  • (9) The effect of calcium(II)acetate (CaAcet) and magnesium(II) acetate (MgAcet) on nickel(II) uptake in the lungs of strain A mice and on the nickel(II)-induced changes in the pulmonary DNA synthesis were studied in order to elucidate the mechanism(s) of inhibitory action of CaAcet and MgAcet upon nickel(II) tumorigenesis.
