    Notizen: Summary Applying the indirect fluorescent antibody technique to the infective stages of the hookwormAncylostoma caninum, it appeared that they do not show IgG antibody binding when serum from dogs infected withA. caninum was used in the test (antiserum). However, inhibiting these stages metabolically with azide or with low temperatures, IgG antibody binding to the outer surface was observed. When the inhibitory factors were removed, shedding of fluorescent substances was seen, which were obviously coming from the outer surface of the larvae. This suggests that shedding of the antigen might occur.

    Notizen: Summary The Indirect Fluorescent Antibody Technique (IFAT) and the Indirect Immuno Peroxidase Technique (IIPT) have been applied to cryostat sections and intact stages of the hookworm speciesAncylostoma caninum with sera from infected dogs. Especially the role of the body surface (=cuticle (cortex, matrix, basal layer) and hypodermis) in immunity was studied. Using cryostat sections and dead intact stages as the antigen, specific antibody binding was demonstrated round the ovum membrane and the cuticle of all stages of this hookworm species. Cryostat sections of adult worms showed, that it probably is not the cuticle itself that is antigenic, but that the specific reaction that is observed consisted of a layer, covering the cortex of the cuticle. Infective and parasitic living stages, however, showed no antibody binding in contrast to the free-living stages in which specific antibody binding was demonstrated.

    Beschreibung / Inhaltsverzeichnis: Nitrosolates and Nitrosolatocompounds. III. Synthesis and Structures of Nitrosolate Derivatives of Organosubstituted Compounds of Antimony(V(, Tellurium(IV), and Iodine(III)In solution the derivatives of the nitrosolates of acetic and benzoic acids and of the ions (C6H5)4Sb+, (CH3),Sb+, (C6H5)3Te+, and the derivative of the nitrosolate of acetic acid and of the ion C12H8I+ show ionic or covalent structures, depending on the polarity of the solvent. In the solid state only the derivatives of (C12H5)4Sb+ unequivocally do not display salt character. The structure of (C6H5)4Sb · O2N2C-CH3 was determined by X-ray methods. The compound consists of separated molecules with slightly distorted trigonal-bipyramidonal environment of the antimony atom. The nitrosolato ligand is oxygen bonded to one of the apical positions. According to the electronic spectra of the solutions of the nitrosolate derivatives the nitrosolate ions react in the covalent forms either as uni-dentate ligands with O-coordination or as bidentate chelating or bridging ligands with O,O′-coordination.
    Notizen: Die Acet- und Benznitrosolsäurederivate der Ionen (C6H5)4Sb+, (CH3)4Sb+, (C6H5)3Te+ und das Acetnitrosolsäurederivat des Ions C12H8J+ zeigen in Lösung je nach Polarität des Lösungsmittels ionische oder kovalente Strukturen. Im festen Zustand besitzen nur die Derivate von (C6H5),Sb+ eindeutig keinen Salzcharakter. Die Struktur von (C6H5)4Sb · O2N2C-CH3 wurde röntgenographisch bestimmt. Die Verbindung besteht aus diskreten Molekeln mit leicht verzerrter trigonal-bipyramidaler Umgebung des Antimon-atoms. Der Nitrosolatoligand besetzt eine der axialen Positionen und ist über Sauerstoff gebunden. Kach Aussage der Elektronenspektren der Lösungen der Nitrosolsäurederivate fungieren die Nitrosolationen in den kovalenten Formen entweder als einzähnige Liganden rnit O-Koordination oder als zweizähnige Chelat- bzw. Brückenliganden mit O, O′-Koordination.

    Beschreibung: We report on the calibration of the one-dimensional hydrodynamic lake model DYRESM to simulate the water temperature conditions of the pre-alpine Lake Ammersee (South-east Germany) which is representative of deep and large lakes in this region. Special focus is given to the calibration in order to reproduce the correct thermal distribution and stratification including the time of onset and duration of summer stratification. To ensure the application of the model to investigate the impact of climate change on lakes, an analysis of the model sensitivity under stepwise modification of meteorological input parameters (air temperature, wind speed, precipitation, global radiation, cloud cover, vapor pressure, and tributary water temperature) was conducted. The total mean error of the calibration results is –0.23 °C, the root mean square error amounts to 1.012 °C. All characteristics of the annual stratification cycle were reproduced accurately by the model. Additionally, the simulated deviations for all applied modifications of the input parameters for the sensitivity analysis can be differentiated in the high temporal resolution of monthly values for each specific depth. The smallest applied alteration to each modified input parameter caused a maximum deviation in the simulation results of at least 0.26 °C. The most sensitive reactions of the model can be observed through modifications of the input parameters air temperature and wind speed. Hence the results show that further investigations at Lake Ammersee, such as coupling the hydrodynamic model with chemo-dynamic models to assess the impact of changing climate on biochemical conditions within lakes, can be carried out using DYRESM.

    Beschreibung: Measurements of trace metal ratios in foraminiferal calcite are routinely used to reconstruct paleoceanographic conditions. Analyses using solution-based inductively coupled plasma mass spectrometry (ICP-MS) require dissolution of the entire foraminifer shell. The potential exists for contamination from adherent clays, mineralized coatings, and other diagenetic components that confound the biogenic trace metal signal. We present results from a cleaning experiment on fossil specimens of the planktic foraminifer Orbulina universa that were cracked into several shell fragments and subjected to different cleaning protocols. We use LA-ICP-MS depth profiling to evaluate the effects of reductive, oxidative, and chelating (DTPA) cleaning protocols on shell Mg/Ca and Ba/Ca ratios. Using the natural pattern of intrashell Mg/Ca heterogeneity exhibited by O. universa , we demonstrate that reductive and oxidative cleaning can dissolve shell calcite from available surfaces, although intrashell Mg/Ca minima and maxima are unaffected. High-resolution depth profiles can be used to identify areas of heterogeneous intrashell Ba/Ca, which can be excluded from computations of whole-shell Ba/Ca. The size and density of shell pores plays a major role in the degree of contamination from sedimentary material. We demonstrate an approach for computing whole-shell Me/Ca ratios from LA-ICP-MS depth profiles that accounts for potential contamination and diagenetic overprinting.

    Beschreibung: We evaluated the impact of staging procedures to detect asymptomatic distant metastases (DM) in the management of women with operable invasive breast cancer (BC, entire cohort: n = 866). Out of 472 patients with lymph node (LN)-negative disease (pN0), DM were found in four cases (detection rate: 0.8%). All four patients presented with established risk factors: hormone receptor (HR)-negative status, HER2-positive status, n = 3; ‘triple-negative’ disease, n = 1. Considering the subgroup of LN-negative patients whose tumors showed the risk factor ‘negative HR status’ ( n = 66), the detection rate of DM was 6%. The detection rates of DM in higher pN categories were as follows: pN1:1.7%; pN2:9.5%; pN3:13.5%. We generally support the international guidelines, including those published by the European Society for Medical Oncology (ESMO) which emphasize that patients with early-stage BC do not profit from radiological staging for the detection of DM and recommend refraining from this. However, we would expand these guidelines and propose that screening should be carried out in node-negative patients whose tumors show established tumor-related risk factors (e.g. HR-negative and HER2-positive status), since in this particular subcohort, the detection rate of DM is with 6% similarly high as that of patients with four to nine positive LNs.
