    Free Oxygen Radicals Are Not Detectable by Chemiluminescence during Human Natural Killer Cell Cytotoxicity (1984)

    Notes: Mononuclear cells isolated from peripheral blood of normal donors produce free oxygen radicals (FR), delectable by chemiluminescence (CL). when interacting with target cells during natural killer (NK) cell lysis. FR-producing cells were found to have monocyte characteristics and gave a positive CL reaction when mixed at low concentration (0.5%) with purified NK cells. No correlation was found between susceptibility to NK cell lysis and capacity to induce CL with different target cell lines. Using high and low molecular FR scavengers, no NK cell inhibition was seen with superoxide dismutase, cytochrome c, and catalase, whereas some inhibition was seen with 4,5-dihydroxy-in-benzcnedisulphonic acid (Tironø) and 2,3-dihydroxybenzoatc. These compounds, however, required higher concentraiions than used for inhibition of CL, suggesting an alternative action of these compounds. Normal levels of NK cell activity were found in two patients with chronic granulomatous disease, who were genetically incapable of producing detectable amounts of FR. As a result, it is concluded that human NK cells do not produce large amounts of FR during killing and that FR are unlikely to be the lytic end product. Nevertheless, neither a low degree of FR formation in NK cells nor a more subtle signal-transmitting role of FR during NK cell triggering can be excluded.

    Neutrophil Chemotaxis Defect in IgA Deficiency Evaluated by Migration Agarose Method (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Scandinavian journal of immunology 11 (1980), S. 0

    Topics: Medicine
    Notes: The chemotactic and random mobility functions of twelve selectively IgA-deficient patients were evaluated by a method using agarose gel. A severe polymorphonuclear cellular chemotactic defect was found in ten out of twelve patients, but only five of them also showed a marked associated impairment of random locomotory function. Furthermore, in one subject, levamisole therapy resulted in a dramatic improvement of both chemotactic and random mobility functions. These results are discussed in the paper with respect to the possible pathogenetic implications.

    Description / Table of Contents: Résumé On a déterminé, pour cinq adhésifs époxy de composition inconnue, les températures de transition vitreuseT g et les effets thermiques de polymérisationΔH. A partir de la variation deΔH en fonction du temps de recuit et par une méthode de calcul itératif, un ordre cinétique phénoménologique de la vitesse de polymérisation à 100° a pu être obtenu. Pour la plupart des adhésifs étudiés l'existence d'un pic double de polymérisation et d'une double transition vitreuseT g permet de supposer qu'il s'agit de copolymères greffés.
    Abstract: Zusammenfassung Die Glas-Übergangstemperaturen (T g) und dieΔH thermische Effekte der Polymerisation wurden für fünf Epoxy-Klebstoffe unbekannter Zusammensetzung bestimmt. Aus den TrendsΔH gegenübert cure war es möglich eine phenomenologische kinetische Ordnung der Polymerisationsgeschwindigkeit bei 100° durch ein iteratives Berechnungsverfahren zu ermitteln. Für die meisten untersuchten Klebstoffe besteht der Grund — Doppelpeak der Polymerisation und doppeltesT g-Signal — sie als Pfropfcopolymere zu betrachten.
    Notes: Abstract The glass transition temperatures,T g, and thermal effects of polymerization,ΔH, have been determined for five epoxy adhesives of unknown composition. From the trendsΔH vs./t cure it has been possible to attain a phenomenological kinetic order of the polymerization rate at 100° through an iterative calculation procedure. For most of the investigated adhesives there are reasons (double peak of polymerization and doubleT g signal) to assume that they are graft copolymers.

    Notes: Abstract For O(N), U(N) and SU(N) groups, we study the weak coupling behaviour of the one-link integrals using their Schwinger-Dyson equations. Special attention is paid to the perturbative corrections to the large N limit. In the case of unitary groups, the 1/N 2 correction is obtained explicitly.

    Notes: Abstract The case of an infant female aged 1 month with severe infections, failure to thrive, and skin erythroderma is reported. Immunological studies demonstrated a severe combined immunodeficiency (SCID) with B cells and normal serum IgM levels. Studies of T-cell subpopulations showed a defect of a subset of T helper cells. Possible pathogenetic mechanisms are discussed.

    Description / Table of Contents: Zusammenfassung Die Adsorption von Benzol anα-Fe2O3- undγ-Al2O3-Pulvern bei Raumtemperatur wurde mittels Wärmefluß-Kalorimetrie und FT-IR-Spektroskopie untersucht. Beim Eisenoxid folgt auf dem Chemisorptions-Verbrennungs-Schritt ein bei Raumtemperatur reversibler, stark exothermer Adsorptionsschritt. Aluminiumoxid besitzt einige Oxydationszentren, sofern keine reduzierende Vorbehandlung erfolgt. Zwei aufeinanderfolgende reversible Adsorptionsschritte treten auf und werden der Wechselwirkung mit zwei verschiedenen Typen von Oberflächenhydroxylgruppen zugeschrieben.

    Notes: Abstract The adsorption of benzene at room temperature onα-Fe2O3 and onγ-Al2O3 powders was investigated by heat-flow microcalorimetry and FT-IR spectroscopy. On iron oxide a chemisorption-combustion step is followed by a highly exothermic adsorption step, reversible at r.t. Few combustion centres exist on alumina if reducing pretreatment is not carried out. Two reversible adsorption steps are subsequently observed and were interpreted as due to interaction with two different types of surface hydroxy groups.
