    Different serum soluble Fas levels in patients with allergic rhinitis and bronchial asthma (1999)
    Copenhagen : Munksgaard International Publishers
    Allergy 54 (1999), S. 0 
    Details
    ISSN: 1398-9995
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Background: The pathogeneses of allergic rhinitis and bronchial asthma are believed to be closely mutually related because of the similar dynamics of allergy-inducing cells and molecules and clinical overlap. In this study, we compared these diseases in the dynamics of cell apoptosis-regulating molecules. Methods: Allergic rhinitis patients (n=36), bronchial asthma patients (n=22), and healthy subjects (n=32) were subjected to measurement of serum (soluble Fas) (sFas) levels during the stable and attack disease phases by a sandwich enzyme-linked immunosorbent assay. Results: Serum sFas levels in patients with allergic rhinitis during the attack phase were significantly lower (P〈0.0001) than those in healthy individuals. There were no differences between them during the attack and stable disease phases. In contrast, serum sFas levels in patients with bronchial asthma during the attack phase were higher (P〈0.0005) than those in healthy individuals. Interestingly, the levels during the attack phase were lower (P〈0.002) than those during the stable phase. Conclusions: Our results suggest a different pathogenesis for allergic rhinitis and bronchial asthma at the cell apoptosis-linked step.

    Investigation of electron density and velocity distribution in high-pressure discharges for excimer laser pumping using laser Thomson scattering (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 70 (1991), S. 41-45

    ISSN: 1089-7550

    Topics: Physics
    Notes: Thomson scattering from plasmas in high-pressure discharges for rare-gas halide excimer laser pumping was observed using an yttrium-aluminum-garnet laser with a second harmonic generator, combined with a double-monochromator to reject large signal from Rayleigh scattering. The results showed the electron velocity distribution to be Maxwellian which was different from prediction of computer simulations, while variation of electron density and temperature with time and gas composition was consistent with results of computer simulations.

    Visible and uv spectra of a polydiacetylene with a side group conjugated to the main chain (1990)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 93 (1990), S. 5510-5517

    Notes: The polarized reflection spectra of single crystals of PDA-CPDO [poly-1-(N-carbazolyl)penta-1, 3-diyn-5-ol], which are π conjugated between the side groups and the main chain, have been measured in the photon energy region from 1.38 to 32 eV for the first time with a polarized synchrotron radiation source. Absorption spectra have been calculated using the Kramers–Kronig relation. Transitions in the visible absorption spectrum, which have been previously attributed to an interband transition in a similar polydiacetylene, have been found to be highly dichroic with respect to the direction along the polymer backbone. The absorption spectrum in this region reveals two broad (ΔE(approximately-greater-than)0.4 eV) peaks at 1.9 and 2.7 eV with an almost equal absorption coefficient of 7.5×104 cm−1. The spectral features in the range from 3 to 8 eV result from electronic transitions of the carbazolyl side groups. A single broad (ΔE∼10 eV) absorption band observed at 18 eV is due to either transitions of σ electrons to higher σ* or π* states of the carbazolyl group, or to ionization processes.

    Preliminary electron density profile and fluctuation measurements on GAMMA 10 using ultrashort-pulse reflectometry : Proceedings of the 12th topical conference on high temperature plasma diagnostics (1999)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 70 (1999), S. 1042-1045

    Notes: The use of ultrashort pulses (full width at half-maximum=1–100 ps) as a source of broadband, time-resolved radiation has high potential for application in microwave diagnostics for fusion plasmas. Here we report on the ultrashort-pulse reflectometry system developed for electron density profile and fluctuation measurements on the GAMMA 10 tandem mirror. The four-channel system (selectable frequencies of 8–17 GHz at 1 GHz intervals) measures the double-pass time-of-flight from the vacuum window to the cutoff layer. The hardware has an uncertainty of ±40 ps and can be operated at a repetition rate of 400 kHz. The system is operational, however, data from plasma experiments is unavailable at the moment. Results from a single-channel O-mode system show time-of-flight measurements consistent with values calculated from profiles obtained by a scannable single-channel interferometer. Fluctuation measurements are also consistent with results from a Fraunhofer diffraction diagnostic. These results suggest that with further refinements, ultrashort- pulse reflectometry will yield a simple yet reliable diagnostic for fusion devices. © 1999 American Institute of Physics.

    The Relationship Between Consumption of Antimicrobial Agents and the Prevalence of Primary Helicobacter pylori Resistance (2002)
    Oxford, UK : Blackwell Science Ltd
    Helicobacter 7 (2002), S. 0 
    Details
    ISSN: 1523-5378
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Medicine
    Notes: Background. Primary and acquired resistance to the antimicrobial agents is a primary reason for the failure of Helicobacter pylori eradication therapies. We assessed the primary antibiotic resistance rates of H. pylori to three different antibiotics and its relationship due to the annual antibiotic consumption in Japan during the period prior to approval of anti-H. pylori therapy in Japan.Materials and Methods. Antibiotic susceptibility was tested using the agar dilution method for clarithromycin, amoxicillin and metronidazole. Isolates were considered resistant when the MIC value was 〉 8 mg/l for metronidazole, 〉 1 mg/l for clarithromycin and 〈 0.5 mg/l for amoxicillin.Results. Helicobacter pylori isolates were obtained from 593 Japanese patients from 1995 to 2000. Primary resistance of H. pylori to clarithromycin, metronidazole and amoxicillin was found in 11%, 9% and 0.3% strains, respectively. The proportion with clarithromycin resistance significantly increased from 7% in 1997–98 to 15.2% in 1999–2000 (p = .003). During the same period the metronidazole resistance rate also increased from 6.6% in 1997–98 to 12% in 1999–2000 (p = .02). The prevalence of clarithromycin and metronidazole was related to the annual consumption of these antimicrobial agents.Conclusion. Resistance rates for both clarithromycin and metronidazole appear to reflect the annual consumption of these agents. The high rate of clarithromycin resistance in Japan suggests that the effectiveness of clarithromycin-based therapies may be compromised in the near future.
