    Theoretical study on the outer- and inner-valence ionization spectra of H2O, H2S and H2Se using the SAC-CI general-R method (2001)

    Notes: The outer- and inner-valence ionization spectra of the Group VI hydrides H2O, H2S and H2Se below the double-ionization threshold were studied by the SAC-CI (symmetry-adapted-cluster configuration-interaction) general-R method. The SAC-CI method quite accurately reproduced the experimental spectra of these hydrides and gave detailed characterizations of the shake-up states. Several unknown satellite peaks were predicted. The shake-up state which includes excitations to the Rydberg orbitals was found to be very important for describing the satellite peaks of these hydrides. A detailed inner-valence satellite spectrum of H2Se is theoretically proposed prior to any experimental observation. © 2001 American Institute of Physics.

    The current status of theory and practice on rail integrity in Japanese railways—rolling contact fatigue and corrugations (2003)

    Notes: The paper describes the Japanese understanding and practice with regard to wheel rail interface problems and their management. Rolling contact fatigue, especially squat defects, grinding, corrugations and lubrication, have been considered. The understanding has been developed through a combination of theoretical modeling, laboratory-based experiments and field trials. Measures have been introduced to mitigate the detrimental effects of these problems and are resulting in benefits to the Japanese railway companies. However, more work is required to better understand wheel rail interface problems and to provide effective solutions.

    Isolation of ortho- and paramyxoviruses from migrating feral ducks in Hokkaido (1982)

    Topics: Medicine
    Notes: Summary A total of 18 hemagglutinating agents were isolated from 14 of 278 migrating feral ducks in Hokkaido during the surveillance studies conducted from 1978 to 1981. Seven of the 18 isolates belonged to paramyxovirus and the rest to influenza A virus. Five isolates of paramyxovirus reacted specifically with antiserum to duck/HK/199/77 and 7 isolates of influenza A virus possessed the antigenic configuration of H10N3. Three of the isolates possessed an hemagglutinin that has no antigenic relation to any of the 26 known strains of avain, swine, equine and human influenza A viruses.

    Notes: Summary This study presents measurements of serum vitamin D metabolites, calcium and phosphorus as well as measurements of the equilibrium dissociation constant for duodenal 1,25(OH)2D3 receptor in 15-, 18-, 19-, and 20-day chick embryos in comparison to that in 1- and 118-day-old chicks and to vitamin D-deficient chicks. The present results showed that: (a) serum 1,25(OH)2D and 24,25(OH)2D levels rise from 15 and 18 to days 19 and 20 of embryonic development while serum phosphate levels are stable; (b) serum calcium levels rise at hatching to adult levels; (c) the duodenal 1,25(OH)2D3 receptor is detectable in 15-day-old embryo and has a Kd similar to that of 118-day-old vitamin D-replete chicks; and (d) the activity of 1,25(OH)2D3 receptor in chick duodenal cytosol is maximal at hatching.

    Plasma 1,25-dihydroxyvitamin D concentrations in cords, newborns, infants, and children (1980)

    Notes: Summary Plasma 1,25-dihydroxyvitamin D [1,25-(OH)2-D] was measured in cord serum, newborns, infants, and children. The mean for the values obtained from the six cords was significantly higher than the mean for the older children (6–15 years). The mean for the six newborns (0–1 week) was significantly higher than that for the older children. The mean for the nine infants (1 week-6 months) and the 14 younger children (6 months-6 years) was significantly higher than that for older children. The present study suggests that the perinatal period is associated with a marked increase in 1,25-(OH)2-D.

    Notes: Abstract. Using the G-monopole invariant, we shall show that any anti-holomorphic involution on a closed symplectic 4-manifold is not diffeomorphic to any holomorphic involution. As a corollary, we shall give a way to construct exotic smooth structures.

    Activity of renal 25-hydroxyvitamin D3-1α-hydroxylase in a case of X-linked hypophosphataemic rickets (1984)

    Notes: Abstract In 1974, a 2-year-old boy was diagnosed as having X-linked hypophosphataemic rickets (XLH) because of severe rickets and hypophosphataemia. The vitamin D metabolite concentrations, blood and urine chemistry and renal 25-hydroxyvitamin D3 (25 OHD3)-1α-hydroxlase were measured in 1982 (about 2 weeks after withdrawal of medication). 1α-hydroxylase was 392 pg/mg tissue/20 min in the patient, which was high compared with aged-matched controls (69.7±28.5 pg/mg tissue/20 min, mean ±SD, n=7). Our present studies showed that the 1α-hydroxylase activity in the patient with XLH was elevated. Therefore, the normal or low 1,25-dihydroxyvitamin D3 (1,25-(OH)2D3) concentrations in XLH patients could be due to accelerated catabolism of 1,25-(OH)2D3 or abnormally regulated 25OHD3-1α-hydroxylase in response to hypophosphataemia, although significantly elevated above that in normal controls.

    Secondary hyperparathyroidism with 1,25-dihydroxyvitamin D deficiency and pseudohypoparathyroidism in childhood: Relationship between plasma 1,25-dihydroxyvitamin D and parathyroid hormone levels and urinary cyclic AMP response to exogenous PTH (1981)

    Notes: Abstract In order to clarify the complex interrelationship between serum calcium, 1,25-dihydroxyvitamin D (1,25(OH)2D), and parathyroid hormone (PTH), and the urinary excretion of cyclic AMP (cAMP) in response to exogenous PTH in pseudohypoparathyroidism (PHP) and related diseases, we investigated 3 patients with parathyroid disorders before and after treatment with 1α-hydroxyvitamin D3 (1α-OH-D3). Low plasma 1,25(OH)2D before treatment increased after giving 1α-OH-D3 (0.1 μg/kg/day), where-as high plasma PTH measured by the C-terminal assay (C-PTH) decreased in all 3. No response in urinary cAMP was found before or after treatment in 2 patients with PHP type I, despite the fall of plasma C-PTH. However, in one patient with extremely high plasma C-PTH but normal N-PTH (measured by a homologous radioimmunoassay using 1–34 human PTH), urinary cAMP response to exogenous PTH was increased after treatment with 1α-OH-D3. We suggest that he had pseudopseudohypoparathyroidism (PPHP) with Albright's hereditary osteodystrophy and a partial deficiency of renal 1α-hydroxylase. In this patient secondary hyperparathyroidism is thought to be due to 1,25(OH)2D deficiency, and the decreased responsiveness to exogenous PTH before treatment due to excess PTH occupying renal receptors.

    Notes: Summary Influenza C viruses did not possess neuraminidase activity when examined using either fetuin or sialyllactose as substrate. Purified preparations of influenza C virus inhibited hemagglutination by NWS hemagglutinin. The hemagglutination inhibiting activity was a bolished by treatment of influenza C virus with neuraminidase. These findings indicated the absence of neuraminidase activity on influenza C virus particles.

    Notes: Summary Blood circulation in guinea pig cochlea was studied using a new “Ultraparc”-microscope with especially intensive light source and long-distance focus. Alterations after application of ephedrinelike substances were observed. We assume that there are alpha- and beta-adrenergic receptors within cochlea vessels, that noradrenaline produces vascular disturbance of the cochlea vessels and that after administration of isoproterenol an vasodilating effect could be shown.
