    Notes: Summary An enzyme linked immunoassay was developed using the microtiter system to measure platelet-associated IgG (PAIgG). One single determination needs 2×106 platelets usually obtained from 3 ml blood anticoagulated with EDTA. Platelets are incubated with peroxidase-conjugated anti-human IgG. Its unbound fraction is adsorbed to an IgG coated microtiter plate, quantitated by a colour reaction and found to be inversely related to the amount of PAIgG. Healthy donors (n=40, aged 1 day to 35 years) possessed 3.6±2.0 (mean±S.D.) fg IgG/platelet. Increased levels of PAIgG were found in patients with acute (n=16) and chronic (n=5) idiopathic thrombocytopenic purpura. Postrecovery platelets had normal values of PAIgG. Widely varying levels of PAIgG were found in patients with freshly diagnosed acute lymphocytic leukemia.

    Notes: Die Oberflächenspannung des Quecksilbers im höchsten Vakuum liegt zwischen dem Anfangswert und dem Endwert der Oberflächenspannung in Luft. Bei Zinn konnte eine Veränderung der Oberflächenspannung mit der Zeit im Vakuum von 5·10-5 mm Hg nicht festgestellt werden. Thallium wies eine Zunahme der Oberflächenspannung mit der Zeit im Vakuum von 10-5 bis 10-4 mm Hg auf. Aus diesen Feststellungen wurde geschlossen, daß dort, wo beim Quecksilber Veränderungen der Oberflächenspannung mit der Zeit vorliegen, die sich einstellenden Oberflächenspannungen sich als Resultierende zwischen den Einflüssen der Anordnung der Metallatome der Oberfläche und der ein- und angelagerten Gasatome ergeben.

    Notes: Vapor phase decomposition-droplet surface etching-graphite furnace atomic absorption spectroscopy (VPD-DSE-GFAAS) is discussed as a technique for the determination of low levels of metals in chemical oxides on silicon surfaces. The VPD-DSE-GFAAS technique was found to be statistically equivalent to results obtained by the standard surface techniques of total reflectance x-ray fluorescence spectroscopy (TXRF) and SIMS. The capability of the VPD-DSE-GFAAS technique has been extended to detection limits in the 107 to low 109 atom cm-2 range. A positive linear relationship was found for iron, calcium, zinc and aluminum deposited on a silicon wafer from an ammonium hydroxide-hydrogen peroxide-water (SC1) solution. Sodium and potassium deposition from SC1 solutions was found to be independent of solution concentrations. Deposition for these metals appeared to be primarily related to localized micron-sized nuclei deposits and not to adsorption on an atomic scale.

    Notes: Results obtained from scanning transmission electron microscopy combined with energy-dispersive X-ray imaging (EDX) and from Rutherford backscattering spectroscopy (RBS) of implanted and multilayered structures are compared in order to demonstrate the depth profiling capabilities of both analysis methods, especially at interfaces. Typical samples for dilute and concentrated systems are compared. The dilute system is represented by Ge nano-clusters in an amorphous SiO2 matrix on a Si substrate produced by ion implantation and subsequent annealing. The concentrated system of alternating Ag-Al multilayers (typical thickness ∽200 nm) is produced by evaporation on Si substrates under high vacuum conditions. A significant advantage of STEM-EDX is the two-dimensional mapping and depth profiling of light and heavier elements in heavy-Z substrates (depth scale in nanometres) without the lack of a deteriorating depth resolution at increasing depth, as happens in RBS. © 1998 John Wiley & Sons, Ltd.

    Description / Table of Contents: The properties of 3β-hydroxysteroides were modified by their conversion with polymer carriers and with polymerizable monomers, respectively. The acetalization was carried out under mild reaction conditions. In dependence of the nature of the 3β-hydroxysteroide and the solvent, respectively, acetals with an degree of conversions up t o 15% were obtained. Polymer carriers were prepared by radical polymerization of vinylacetate - crotonaldehyd. Dextranaldehyd was prepared by oxidation of dextran with NaIO4 Polymeric steroidesters were prepared by conversion of Sβ-hydroxy-steroides with methacryloylchloride and subsequent radical copolymerization with methacrylic acid.
    Notes: Zur Eigenschaftsmodifizierung polymerer Pharmaka wurden 3β-Hydroxysteroide mit polymeren Trägern bzw. polymerisierbaren Monomeren umgesetzt. Die Acetalisierung erfolgte unter milden Bedingungen und ergab in Abhängigkeit vom eingesetzten 3β-Hydroxysteroid bzw. vom Lösungsmittel Acetale mit einem Umsetzungsgrad von maximal 15%. Als polymere Träger wurden die auf radikalischem Wege hergestellten Copolymere Vinylacetat/Crotonaldehyd sowie der bei der Oxidation von Dextran mit NaIO4 erhaltene Dextranaldehyd eingesetzt. Polymere Ester wurden durch Umsetzung von 3β-Hydroxysteroiden mit Methacrylsäurechlorid und anschließender radikalischer Copolymerisation mit Methacrylsäure erhalten.
