    Notizen: Abstract  Hazelnuts (HNs), widely distributed in sweets, provoke one of the most frequent pollen-associated food allergies. In this study HN allergens were investigated and immunologically characterized, focussing on their heat stability and cross-reactivity with known allergenic structures. Therefore, 27 sera from HN-allergic patients and 28 sera from children with positive CAP classes for HN and birch pollen were submitted to immunoblot and immunoblot inhibition. The major HN allergen was found to present a molecular mass of about 17–18 kDa, and to share IgE epitopes with Bet v 1, the major birch pollen allergen. This allergen was recognized by IgE of 93% of our HN-allergic patients and by 79% of sensitized children. A 48 kDa glycoprotein was identified as a minor HN allergen with cross-reactive carbohydrate determinants. The major N-glycan species was determined by matrix-assisted laser desorption mass spectrometry to be Man3XylGlcNAc2. IgE binding to this protein was detected in sera of 41% of the allergic patients and 61% of the children. Partial N-terminal sequencing demonstrated similarity to legume storage proteins. The IgE reactivity of this structure was partially resistant to heating. The rat basophil leukaemia cell mediator release assay was used for estimation of cross-sensitization between HN and birch pollen, confirming the finding that HNs contain a heat-resistant allergenicity without cross-reactivity to birch pollen allergens.

    Notizen: Abstract A synoptic survey of the distribution and abundance of occurrence of bloom-forming Cyanobacteria in 55 lakes in the Republic of Ireland revealed strong positive correlations with the traditional trophic gradient. Analysis of the data shows that the perceived trophic state may be correctly viewed as a function of phosphorus availability. The distribution of dominant bloom-forming Cyanobacteria is strongly related to the geology of the catchments and the incidence of significant bicarbonate buffering.

    Beschreibung / Inhaltsverzeichnis: A Contribution on Ternary Oxides of the AMO4-Type (A = Ti3+, Cr3+; M = Nb5+, Ta5+)CrNbO4, CrTaO4, TiNbO4, and TiTaO4 were prepared by CO2-laser technique. X-ray single crystal investigations show a random distribution of the metal ions in Rutil type structure, space group D4h14-P42/mnm. Calculations of the free energy of reaction between Ti2O3 and Nb2O5 show higher stability of TiO2 beside NbO2. In TiNbO4 both metals exhibit the oxidation state +4.
    Notizen: CrNbO4, CrTaO4 TiNbO4 und TiTaO4 wurden einkristallin mit CO2-Lasertechnik dargestellt und röntgenographisch untersucht. Sie kristallisieren mit statistischer Verteilung der Metallionen im Rutiltyp, Raumgruppe D4h14-P42/mnm. Berechnungen der freien Reaktionsenthalpie zeigen, daß Ti2O3 nicht neben Nb2O5vorliegt. In TiNbO4 haben beide Metallionen die Oxidationsstufe +4.
