    Notizen: New types of focusing lenses for relativistic electron beams (REBs) are proposed, and preliminary experimental results are obtained. The principle of the lenses is as follows: When REBs are injected into the small apertures of cylindrical superconducting lenses, self-magnetic fields of the REBs are perfectly confined in a region between the REBs and the wall of the lenses. The REBs are focused by those compressed fields. The superiority of superconducting lenses was shown using foilless REB diodes which were operated at 0.15-Torr Ne and had high-Tc , cylindrical superconductor anodes made of Y-Ba-Cu-O compounds (axial lengths of 30 and 145 mm and an inner diameter of 20 mm). The focused REBs (0.8 kA, 270 keV, pulse widths of less than 5 ns) had main beam diameters less than 2 mm.

    Notizen: We have measured the low-frequency voltage noise properties across mesa stacks of intrinsic Josephson junctions in Bi2Sr2CaCu2Oy (BSCCO) single crystals as a function of bias voltage. The BSCCO mesas with area of 160×40 μm2 were fabricated on the surface of cleaved BSCCO single crystals using standard photolithography and Ar ion-milling techniques. The measured noise voltage spectrum density SV(f ) had a 1/f dependence on frequency. The magnitude of the 1/f noise spectra was found to increase monotonically with the branch number in the I–V characteristic at fixed bias current, and no anomalously enhanced 1/f noise was observed. © 2001 American Institute of Physics.

    Surface reconstruction of TiC(001) and its chemical activity for oxygen (1999)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 75 (1999), S. 3784-3786

    Thema: Physik
    Notizen: The TiC(001) surface has been observed by scanning tunneling microscopy with atomic resolution in ultrahigh vacuum. After the sample was cleaned by repeated heating at ∼1300 °C, we observed the 1×1 structure. On the other hand, the (square root of 2)×(square root of 2) structure due to the ordered carbon vacancies formed when the sample was annealed at ∼1150 °C. We demonstrated the chemical activity of carbon vacancies of both structures for oxygen. The TiC(001)-1×1 surface with intentionally increased carbon vacancies and the TiC(001)-(square root of 2)×(square root of 2) surface changed to a defect-free 1×1 structure with a small amount of oxygen, owing to the preferential adsorption of oxygen on the carbon vacancies. © 1999 American Institute of Physics.

    Assay for detecting IgE and IgG antibodies against Candida albicans cell-wall mannan (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Allergy 53 (1998), S. 0 
    Details

    Thema: Medizin
    Notizen: In the present study, we assayed mannan-specific IgE and IgG antibodies in samples of serum isolated from blood collected from adult patients with bronchial asthma, using a liquid-phase method with a polysaccharide, mannan (Mn), purified from Candida albicans (C. alb), and investigated the relationships of allergenicity among a crude extract of C alb. purified Mn. and acid protease (AP). The correlations between the titers of anti-Mn A and anti-Mn B IgE and IgG were very strong, and the levels of inhibition of anti-Mn A IgE and IgG reactions by Mn A and Mn B were almost identical. Although no common allergenicity was observed between Mn A and AP because there was no correlation between the titers of anti-Mn A and anti-AP IgE, and no inhibition of the anti-Mn A IgE reaction by AP, both antigens were found to exist in crude C alb. The level of inhibition of anti-crude C. alb IgG reaction by Mn A or Mn B was about 60%. Approximately 70% inhibition of the anti-Mn A IgE reaction was observed for eight different fungal allergen extracts, but no inhibition was observed for 11 of the other fungal allergen extracts tested. The above results indicate that common antigenicity was observed between Mn A and Mn B in the human IgE and IgG antibody production system, and the cross-allergenicity observed among some fungi was considered to be the result of the common antigenicity of Mn isoforms.

    A Sero-Epidemiological Survey of Gelatin Sensitization in Young Japanese Children During the 1979–1996 Period (2005)
    Oxford, UK; Malden, USA : Blackwell Science Ltd
    Scandinavian journal of immunology 61 (2005), S. 0

    Notizen: Recently, an increasing number of adverse reactions in children inoculated with live attenuated virus vaccines containing gelatin have been reported. However, the distribution, magnitude and rate of gelatin sensitization in the Japanese population have not been established. Here, the purpose was to investigate the distribution of children with positive gelatin immunoglobulin G (IgG) and/or IgE in Japan and to ascertain whether the incidence of positive antigelatin antibody cases among the general population, as reflected in the sample employed here, has been increasing during the period in question. The presence of IgE and IgG antibodies were measured against gelatin in 1600 panel sera collected from different age groups of Japanese children in Hokkaido/Sapporo from 1979 through 1996. Among the subjects, 39 had gelatin IgG- and/or IgE-positive sera, and these were correlated with the time of obtaining the sera as well as with the age of the subjects. The older the subject and the later the period, the higher the sero-incidence. Japanese children have become increasingly sensitized to gelatin, especially since the mid-1990s.

    Single nucleotide polymorphism genotyping of the barley waxy gene by polymerase chain reaction with confronting two-pair primers (2004)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 123 (2004), S. 0 
    Details

    Notizen: A high-throughput single nucleotide polymorphism (SNP) genotyping procedure was developed to select amylose-free barley mutants whose waxy genes had a C- to T-base substitution in exon 5, which converted Gln-89 of the wild-type gene into a termination codon. An F2 population carrying an amylose-free waxy gene was checked for segregation. Polymerase chain reaction with confronting two-pair primers (PCR-CTPP) produced allele-specific PCR products that have different sizes and are inherited in a co-dominant manner. Two alleles of the barley waxy gene with SNP were correctly identified in parental strains using the PCR-CTPP procedure. Segregation of the SNP as detected by PCR-CTPP in an F2 population fitted the expected 1:2:1 ratio. The PCR-CTPP procedure can provide a time saving and cost-effective alternative to derived cleaved amplified polymorphic sequence in marker-assisted selection.

    Inheritance and stability of the virus-resistant gene in the progeny of transgenic sweet potato (2002)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 121 (2002), S. 0 
    Details
    ISSN: 1439-0523

    Notizen: Viral diseases of sweet potato are very prevalent and often seriously damaging to the plants. In particular, the severe strain of the sweet potato feathery mottle virus (SPFMV-S) causes ‘obizyo-sohi’ disease in Japan. In order to confer viral resistance against SPFMV using current biotechnology, a transgenic sweet potato has been produced, introducing hygromycin-resistant (hpt) and SPFMV-S coat protein (CP) genes, which have shown a significant resistance to SPFMV-S. In the breeding programme, it is important to confirm that the viral resistance conferred in T0 plants can be inherited by their progeny. In the present study, progeny were obtained from crosses between the transgenic T0 and a non-transgenic variety of sweet potato. The results showed that the CP gene was inherited by the next generation and that the stability of viral resistance was also confirmed. Thus, this production system for the virus-resistant transgenic sweet potato is useful in practical breeding.

    The lymphoproliferative response to enzymatically digested gelatin in subjects with gelatin hypersensitivity (2000)
    Oxford BSL : Blackwell Science Ltd
    Clinical & experimental allergy 30 (2000), S. 0 
    Details

    Thema: Medizin
    Notizen: 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.
