    Notes: Absorption and luminescence saturation of confined excitons are measured using a single-beam method for CuCl microcrystals with various radii embedded in NaCl single-crystalline matrices. From the excitation-intensity and microcrystal-size dependencies of their saturation, the effective saturation density of excitons, which is inversely proportional to the magnitude of optical nonlinearity, proves to be inversely proportional to the volume of microcrystals with effective radii of less than 5 nm at 77 K. Therefore, the optical nonlinearity of these microcrystals is not a function of microcrystal radii, but of the number of excitons created in a microcrystal, indicating the characteristic nature of coherent exciton confinement. © 1996 American Institute of Physics.

    Hydration of Succinic Acid by Ultrasonication and its Effects on Taste (2002)

    Notes: : We have investigated the possible changes in the hydration of succinic acid aqueous solution by weak ultrasonication based on 1H-NMR measurements, and observed its effects regarding taste by sensory evaluation. The 1H-NMR measurements showed that the peak area of the carboxyl proton was diminished in the succinic acid aqueous solution by ultrasonication and that the water proton was conversely enhanced. This means that weak ultrasonication slightly accelerated the hydration of succinic acid. The sensory evaluation showed that the succinic acid aqueous solution tasted weaker by ultrasonication (p 〈 0.05), though its concentration was unchanged. These results suggest that the slight change in the hydration state produces some changes in taste.

    Developmental process of sun and shade leaves in Chenopodium album L. (2004)
    Oxford, UK : Blackwell Science Ltd
    Plant, cell & environment 27 (2004), S. 0 
    Details

    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: The authors’ previous study of Chenopodium album L. revealed that the light signal for anatomical differentiation of sun and shade leaves is sensed by mature leaves, not by developing leaves. They suggested that the two-cell-layered palisade tissue of the sun leaves would be formed without a change in the total palisade tissue cell number. To verify that suggestion, a detailed study was made of the developmental processes of the sun and shade leaves of C. album with respect to the division of palisade tissue cells (PCs) and the data was expressed against developmental time (leaf plastochron index, LPI). The total number of PCs per leaf did not differ between the sun and shade leaves throughout leaf development (from LPI −1 to 10). In both sun and shade leaves, anticlinal cell division of PCs occurred most frequently from LPI −1 to 2. In sun leaves, periclinal division of PCs occurred synchronously with anticlinal division. The constancy of the total number of PCs indicates that periclinal divisions occur at the expense of anticlinal divisions. These results support the above suggestion that two-cell-layered palisade tissue is formed by a change of cell division direction without a change in the total number of PCs. PCs would be able to recognize the polarity or axis that is perpendicular to the leaf plane and thereby change the direction of their cell divisions in response to the light signal from mature leaves.

    The lymphoproliferative response to enzymatically digested gelatin in subjects with gelatin hypersensitivity (2000)

    Notes: This study was designed to evaluate the immunogenic characteristics of enzymatically digested gelatin, ‘FreAlagin’, employing the lymphoproliferative response in subjects with gelatin hypersensitivity. Our purpose was to assess the response of primed lymphocytes to the newly developed FreAlagin and compare it to the response to conventional gelatin.〈section xml:id="abs1-2"〉〈title type="main"〉MethodsA gelatin-specific lymphocyte proliferation test (LPT) was performed in 110 children with adverse reactions to gelatin-containing vaccines, who showed positive gelatin-specific cell-mediated immunity and were thus diagnosed as having gelatin hypersensitivity. Gelatin-specific IgE was measured in all subjects. The antigenic activity of FreAlagin to lymphocytes was compared with that of conventional bovine gelatin. Positive and negative control specimens were obtained from the patients with anaphylaxis and from subjects inoculated with gelatin-free vaccine who showed no adverse reactions in order to establish the fluorometric ELISA system to determine IgE antibody to gelatin and LPT.〈section xml:id="abs1-3"〉〈title type="main"〉ResultsThe lymphocyte activity against FreAlagin was much less than that to Wako gelatin and more than half of the subjects who reacted positively to Wako gelatin had a negative LPT to FreAlagin. Although 47% of the subjects had positive LPTs to FreAlagin, all but two still had lower SIs to FreAlagin compared with Wako gelatin.〈section xml:id="abs1-4"〉〈title type="main"〉ConclusionWe conclude that the antigenic activity of FreAlagin as measured by the cell-mediated immune response is significantly less than that of conventional bovine gelatin. However, it is still necessary to perform clinical trials to show a reduced or absent clinical reactivity to FreAlagin in sensitized patients to conventional gelatin.

    Gelatin-specific cellular immune responses persist for more than 3 years after priming with gelatin containing DTaP vaccine (2002)

    Notes: Background Gelatin-specific cell-mediated immunity develops in subjects inoculated with gelatin containing DTaP vaccine. However, it is not yet known whether such established sensitization to gelatin disappears or persists with time.Objective The aim of this study was to follow the patients with gelatin sensitization elicited by DTaP vaccination for their lymphocyte responsiveness and IgE, IgG antibody specific to gelatin over several years and to compare the activities with those at the time of enrolment into the study.Methods We studied 28 subjects who developed positive lymphocyte proliferation test (LPT) after receiving gelatin containing DTaP vaccine and eight subjects who had a negative LPT after inoculation of non-gelatin DTaP. Determination of IgE, IgG antibodies and specific lymphoproliferative response directed against gelatin were performed at enrolment and on follow up.Results None of the subjects had antibody to gelatin at enrolment and none developed gelatin IgE or IgG during follow-up. There was no significant difference in the SIs of the subjects receiving gelatin DTaP (P = 0.150, 95% CI, −0.198–0.032), whereas lymphocyte activity to gelatin increased between enrolment and follow-up in the subjects with non-gelatin DTaP (P = 0.011, 95% CI, 0.063–0.338).Conclusion Gelatin-specific lymphocyte activity persists at comparable levels for more than 3 years in subjects who acquire a positive LPT response to gelatin after receiving primary DTaP vaccine containing gelatin. Furthermore, five out of eight subjects initially with negative LPT to gelatin have been shown to acquire specific LPT with time.

    Radiation in a hypersonic shock layer generated around a projectile (1995)

    Notes: Abstract Radiation emitted from the shock layer generated around a hypersonic flight model is experimentally investigated by using a ballistic range (two-stage light-gas gun). A polyethylene projectile of 1.2 cm in diameter is launched in this facility at the velocity of 5 km/sec (M=15), and the emission from the induced shock layer around the projectile is observed with a spectroscope. As a result, molecular band-spectra from NO and N2 are detected along with those from carboncontaining molecules. Total emission power is measured with a diode-type powermeter. In addition, dimension effect of the flight model is theoretically and numerically examined, and a scaling law on thermochemical structure of the shock layer is developed. It shows that the thickness of thermal boundary-layer formed on the model surface does not follow the conventional scaling law based on the reaction distance and on the energy relaxation distance. Finally, the radiative field around the projectile is numerically computed, and the total power emitted from the shock layer is estimated. From the comparison between computed and measured results, the validity of the calculation model is discussed.
