  2. LE cell - Wikipedia

    en.wikipedia.org/wiki/LE_cell

    A lupus erythematosus cell (LE cell), also known as Hargraves cell, is a neutrophil or macrophage that has phagocytized (engulfed) the denatured nuclear material of another cell. [1] The denatured material is an absorbed hematoxylin body (also called an LE body).

  3. Isotope separation - Wikipedia

    en.wikipedia.org/wiki/Isotope_separation

    Isotope separation is the process of concentrating specific isotopes of a chemical element by removing other isotopes. The use of the nuclides produced is varied. The largest variety is used in research (e.g. in chemistry where atoms of "marker" nuclide are used to figure out reaction mechanisms).

  4. Antinuclear antibody - Wikipedia

    en.wikipedia.org/wiki/Antinuclear_antibody

    HEp-2 cells are permeablised (1) and then incubated with a person's blood serum (2). If the serum contains antibodies, they will bind to antigens within the HEp-2 cell nucleus. These antibodies can be visualised by subsequent incubation with anti-human antibodies conjugated to a fluorescent molecule (3).

  5. Weapons-grade nuclear material - Wikipedia

    en.wikipedia.org/wiki/Weapons-grade_nuclear_material

    To reduce the concentration of Pu-240 in the plutonium produced, weapons program plutonium production reactors (e.g. B Reactor) irradiate the uranium for a far shorter time than is normal for a nuclear power reactor. More precisely, weapons-grade plutonium is obtained from uranium irradiated to a low burnup.

  6. Plutonium (IV) oxide - Wikipedia

    en.wikipedia.org/wiki/Plutonium(IV)_oxide

    Plutonium(IV) oxide, or plutonia, is a chemical compound with the formula Pu O 2. This high melting-point solid is a principal compound of plutonium . It can vary in color from yellow to olive green, depending on the particle size, temperature and method of production.

    en.wikipedia.org/wiki/Kaolin_clotting_time

    KCT is similar to the activated partial thromboplastin time test, except it does not use exogenous phospholipid. [2] Thus, a confirmatory test that uses excess phospholipid is needed to validate the presence of lupus anticoagulants. [2] Otherwise, diluting the test plasma in normal plasma before testing provides characteristic mixing patterns. [8]

    Feb. 5—Two workers suffered skin contamination in separate incidents last month at Los Alamos National Laboratory's plutonium facility, the latest in a series of worker-safety lapses at the lab.
