    Notes: Duality identifies recoupling coefficients and isoscalar factors of the unitary groups with matrix elements of double coset representatives of the symmetric groups. When the double coset factorization is with respect to the same subgroup chain the matrix is that of the ordinary irreducible representation in a basis symmetry adapted to the subgroup chain. The invariant character of the symmetric group element then acts as a constraint on the magnitude, phase, and multiplicity resolution for diagonal elements. An algorithm for determining the content of this constraint is given and is shown to be consistent with a phase convention proposed previously.

    Disseminated Spiked Hyperkeratosis (1987)

    Notes: : Multiple small hyperkeratoses were observed in a 42–year-old woman. They had first appeared in early adult life. There was 3 history of an apparently identical disorder affecting her father, her brother, and her brother's son. A similar condition has been described in four previous reports in which seven individual cases have been documented, four had a positive family history, bringing the total number of previously known cases to 14. The disorder is characterized by the development in early adult life of widely disseminated small spikes of keratin that are unrelated to hair follicles. Microscopic examination shows digitate orthokeratosis with moderate epidermal cell hyperplasia and a normal underlying dermis.

    Application of HPLC for the Determination of PSP Toxins in Shellfish (1985)

    Notes: A high performance liquid chromatographic (HPLC) procedure for determination of the toxins associated with paralytic shellfish poisoning (PSP) is compared to the standard AOAC mouse bioassay method on 100 shellfish samples representing a variety of species. For those samples with toxin content below the detection limit of the bioassay (35 μg saxitoxin (STX)/100g) HPLC analysis indicated a similar low level with a range of 〈10 to 56 μg STX/100g (n = 60). A correlation coefficient of 0.92 was determined for the 40 samples exhibiting toxicity in the bioassay (i.e., 〉35 μg STX/100g). Among the advantages of the HPLC method over the bioassay are significantly better sensitivity, greater sample through-put, and ability to determine the levels of each individual PSP toxin.
