    Immunomodulating effects of Toxoplasma gondii occur at an early stage of infection (1984)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 24 (1984), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract Effects of Toxoplasma gondii infection on the host immune responses were investigated at an early stage of infection. The spontaneous generation of chemiluminescence of peritoneal exudate cells was elevated as early as 1 h after infection of mice with the parasite. Significant enhancement of spontaneous chemiluminescence (CL) and increased survival after challenge with relatively virulent toxoplasma were observed in animals infected with avirulent toxoplasma 24 h previously.

    Chromosomal Assignment of Three Enzyme Coding Loci (Icd1, Nad-Mdh1 and Aco1) Using Primary Trisomics in Beet (Beta vulgaris L.) (1993)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Chromosomal assignment of three enzyme coding loci was established by evaluation of the segregation distortion in the offspring of crosses between heterozygous primary trisomics of a complete series in beet (Beta vulgaris) and heterozygous diploid pollinators. Depending on the rate of isozyme polymorphism in the original plant material, at least one, but more often two, crossing cycles were needed to obtain the desired segregating populations. In one case, a backcross was used to confirm the segregation distortion, and in two cases, the chromosomal assignment of the isozyme loci was confirmed by studying the dosage shift in the electrophoretic pattern of the critical trisomics. The isocitrate dehydrogenase locus (Icd1) is situated on chromosome II, the NAD-dependent malate dehydrogenase locus (Nad-Mdh1) on chromosome III, and the aconitase locus (Aco1) on chromosome IV.

    The Diploidised Meiosis of Tetraploid Beta macrocarpa and its Possible Application in Breeding Sugar Beet (1989)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Accessions of Beta macrocarpa Guss., collected on the Canary Islands, were tetraploid (2n = 36). Three of these accessions were studied in detail. The plants were rather uniform in their morphological appearance, both within and between accessions, and were annual and fully self-compatible. Meiosis was completely diploidised, suggesting an alloploid nature of the tetraploid species. Crosses with diploid B. vulgaris yielded triploid hybrids which were sterile or nearly so; a few descendants of such hybrids were highly aneuploid. Crosses between tetraploid B. macrocarpa and autotetraploid cytotypes of B. vulgaris showed variable results, only part of these crosses yielded tetraploid hybrids. The tetraploid hybrids exhibited somewhat higher fertility than the triploids. An F2 generation showed partial hybrid dwarfness, partial fertility and segregation for carliness and coloration of the hypocotyl. All hybrids had multivalents at meiosis (averages: 2.5—5.4 multivalents per pollen mother cell), indicating suppression of the diploidised meiosis. The possibilities of application of the diploidised meiosis in breeding sugar beet are discussed.

    A rapid, apple-based test for virulence in Cryphonectria cubensis isolates (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Forest pathology 28 (1998), S. 0

    Notes: The presence of the Eucalyptus canker pathogen Cryphonectria cubensis in South Africa is of concern to the local forestry industry. Quantification of the virulence of this fungus through the inoculation of trees, is both time consuming, and expensive. In this study, the potential to use apples in screening for virulence of isolates of C. cubensis, was tested using different apple cultivars and inoculation procedures. The best indication of virulence was given on Golden Delicious apples incubated at 25°C for 14 days. Here, the lesion size associated with inoculations of C. cubensis, was found to correlate significantly with the virulence of the isolates, as determined by inoculations on trees.

    Resistance to Polymyxa betae in Beta Species of the Section Procumbentes, in Hybrids with B. vulgaris and in Monosomic Chromosome Additions of B. procumbens in B. vulgaris (1992)

    Notes: Resistance to Polymyxa betae was studied in Beta species of the section Procumbentes, in hybrids of B. vulgaris with B. procumbens or B. patellaris, and in monosomic additions of chromosomes of B. procumbens in B. vulgaris. In all experiments P. betae infested with beet necrotic yellow vein virus (BNYVV) was used. This virus causes rhizomania in sugar beet, and the effect of vector resistance was studied by measuring virus concentrations. Cystosori of P. betae were not found in the wild species and the hybrids. Virus concentrations in these plants were low, and in half the number of plants the virus could not be detected. Results of experiments with the monosomic additions indicate, that resistance to P. betae in B. procumbens is located on chromosomes 4 and 8. Some cystosori were present in these addition types, while cystosori were abundantly present in other addition types and all sib-plants. Virus concentrations in the addition types 4 and 8 were lower than in their sib-plants, but in almost all plants the virus could be detected. A significant correlation (r = 0.91; P 〈 0.05) between average numbers of cystosori and average virus concentrations was found when addition families of type 8 were tested together with B. procumbens and B. vulgaris cv. ‘Regina’.

    Thermal and mechanical properties of selected 3D printed thermoplastics in the cryogenic temperature regime (2015)
    Institute of Physics (IOP)
    Details
    Publication Date: 2015-12-19
    Description: Insulating materials for use in cryogenic boundary conditions are still limited to a proved selection as Polyamid, Glasfiber reinforced resins, PEEK, Vespel etc. These materials are usually formed to parts by mechanical machining or sometimes by cast methods. Shaping complex geometries in one piece is limited. Innovative 3D printing is now an upcoming revolutionary technology to construct functional parts from a couple of thermoplastic materials as ABS, Nylon and others which possess quite good mechanical stability and allow realizing very complex shapes with very subtle details. Even a wide range of material mixtures is an option and thermal treatments can be used to finish the material structure for higher performance. The use of such materials in cryogenic environment is very attractive but so far poor experience exists. In this paper, first investigations of the thermal conductivity, expansion and mechanical strength are presented for a few selected commercial 3D material sam...
