    Notes: Summary Barley yellow dwarf (BYDV) is a group a closely related viruses which cause economic losses in a wide range of graminaceous species throughout the world. Barley plants can be protected from the effects of BYDV by the ‘Yd2’ resistance gene. Plants which contain the ‘Yd2’ gene also contain a constitutively expressed polypeptide which was not found in any plants without ‘Yd2’. Conversely, BYDV susceptible plants contain another constitutively expressed polypeptide which was not found in any of the BYDV-resistant lines examined. These two polypeptides appear to have the same molecular weight (as assessed by SDS-PAGE) and only slightly different iso-electric points. They also appear to contain an extensive range of similar antigenic determinants. Both polypeptides were found in F1 hybrids made from resistant and susceptible plants. We suggest that these two polypeptides are the products of two allelic genes. Analysis of near-isogenic lines showed that the locus which controls the ‘Yd2’ resistance gene and the locus controlling the synthesis of the two polypeptides may be within ± 9 cM of each other. We have developed a Western blot technique which allows assessment of barley lines, 4-days after seed imbibition, for the presence of the ‘Yd2’ gene.

    Studies of the heat lability of mouse anti-Sendai virus immune sera (1971)
    Springer
    Archives of virology 34 (1971), S. 295-300

    Topics: Medicine
    Notes: Summary Immune mouse sera containing antibodies against Sendai virus were found to be heat labile. Sera which were obtained soon after infection were particularly susceptible to heating. Normal mouse serum was found to restore the activity of these heated sera. This suggests that the former contained a heat labile accessory factor which assists the activity of antibody against Sendai virus in mouse sera. It was not possible to demonstrate that this factor was complement.

    Persistence of high titre antibodies to the early antigens of cytomegalovirus in pregnant women (1980)
    Springer
    Archives of virology 64 (1980), S. 303-309 
    Details
    ISSN: 1432-8798
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Serial serum samples were obtained from 45 pregnant women who had been shown to possess complement fixing (CF) antibodies to cytomegalovirus (CMV) during a previous pregnancy. The serial samples were tested for antibodies against the early antigens (EA) and complement fixing antigens of CMV. All of the 45 women still possessed CF antibodies at the commencement of their next pregnancy. Six of the 45 women (13 per cent) lacked detectable IFA-EA antibodies whilst 19/45 (42 per cent) women possessed only low titres (≤64) of these antibodies. However, 20/45 (44 per cent) women possessed high titre (≽128) antibodies despite having experienced their primary CMV infection many months previously. It is concluded that antibodies to the EA of CMV are not as transitory as has been suggested and that their presence, even at high titre, in a serum sample from a pregnant woman cannot be taken as presumptive evidence of recent primary infection with this virus.

    The isolation, identification and synthesis of the alarm pheromone ofVespula squamosa (Drury) (Hymenoptera: Vespidae) and associated behavior (1988)

    ISSN: 1420-9071
    Keywords: Vespula squamosa ; alarm and attack behavior ; N-3-methylbutylacetamide ; southern yellowjacket

    Topics: Biology , Medicine
    Notes: Summary A material that elicits alarm and attack behavior byVespula squamosa (Drury) workers was isolated from venom extracts and identified by spectroscopic methods as N-3-methylbutylacetamide. This compound elicited attack responses from worker wasps identical to those responses observed when venom was applied at the same dosage. This is the first behavioral role reported for this compound.

    Studies of the genetic susceptibility of individuals to infection with influenza viruses (1975)

    Notes: Summary Nearly three and a half thousand sera obtained from various populations were tested serologically to obtain evidence of past infection with influenza A viruses that were prevalent from 1947 to 1972. No significant difference was found between the distributions of the levels of these antibodies of individuals of blood groups A and 0, A1 and 0, Rh (D+) and Rh (D-) and MM, MN and NN. The significance of these findings is discussed.

    Oriented flight responses of female Mediterranean fruit flies to calling males, odor of calling males, and a synthetic pheromone blend (1992)

    Notes: Abstract Male Mediterranean fruit flies,Ceratitis capitata (Wiedemann), produce volatile chemicals thought to be attractive sex pheromones. We demonstrated for the first time that male odor elicits upwind flight and zigzagging upwind flight patterns in mature unmated females. Such flight patterns indicate the mechanisms involved in female location of the pheromone source and arrival at that source. Similar female oriented upwind flight responses occurred with a three component blend comprised of ethyl-(E)-octenoate, geranyl acetate, andE,E-alpha farnesene. These findings clarify the role of male sex pheromone in mate-location strategies in this species and provide new bioassay criteria for evaluating attraction responses to male pheromone and synthetic blends.

    Development of new expanded editions of the Gamma-ray Spectrum Catalogues in electronic format (1998)
    Springer
    Journal of radioanalytical and nuclear chemistry 233 (1998), S. 81b 
    Details
    ISSN: 1588-2780
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract A program has been developed at the INEL to produce new enhanced editions of the original Gamma-ray Spectrum Catalogues for presentation in electronic format. This program has produced the first version of the Catalogues in CD-ROM format and will offer them on the Internet through the Gamma-ray Spectrometry Center Web Site at INEEL. The original content of the Catalogues has been expanded to include integrated decay scheme drawings, tables of related decay data, and updated material on the techniques of gamma-ray spectrometry. All of the original spectral plots, gamma-ray energy and intensity data, and text were converted to digital format, related decay data from the Evaluated Nuclear Structure Data File (ENSDF) and decay scheme graphics were then added, and all data converted to the Adobe Acrobat (PDF) format. Follow-on versions of the catalogues are being expanded to include prompt neutron capture and n-n' spectra and spectra representing the response of large-volume Ge detectors. Large-volume Ge detector spectra will be calculated, using Monte Carlo and parametric fitting techniques presently under development. Examples of content and details of the advanced technology applied to produce these new volumes will be presented. Services and content of the Gamma-ray Spectrometry Center Web Site will also be described.
