    Calculation of the nuclear spin–spin coupling constants. VI. Many-body perturbation theoretic calculation of electron correlation effect (1991)

    Notes: The Fermi-contact contributions to the nuclear spin–spin coupling constants are computed for four first-row hydrides, i.e., HF, H2O, NH3, and CH4 using the finite perturbation many-body perturbation theory (FP-MBPT) through the second order in the electron correlation correction. The calculated values of JXH (X=O,N,C) yield reasonable results, but the calculation for JFH and the geminal JHH (in H2O, NH3, and CH4) presents too large values.

    Growth fraction of human bladder tumors (1991)
    Springer
    Urological research 19 (1991), S. 215-218

    Notes: Summary The growth fraction of bladder tumors was immunohistochemically assessed in situ using anti-DNA polymerase (Pol α) monoclonal antibody. This enzyme is known to be present in the nucleus of the cells in G1, S, and G2 phases. The percentage of labeled cells was expressed as the labeling index (LI). The average LI was 6.0% in normal epithelium and 17.8% in bladder tumors, this difference being significant. The labeled cells were distributed throughout both the basal and surface layers of bladder tumors. However, in some bladder tumors, the distribution of Pol α-labeled cells varied from area to area. The higher fraction of labeled cells was found in high grade or invasive tumors. Papillary and nodular bladder tumors showed a greater rate of cell proliferation than papillary tumors. These findings suggest that Pol α immunostaining could be a potent tool for easy and quick evaluation of proliferating cells in bladder tumors, there-by providing a supplement to conventional histological findings.
