    An ELISA for measuring serum antibodies to Actinobacillus actinomycetemcomitans (1980)

    Notes: An adaptation of the indirect enzyme-linked immunosorbent assay (ELISA) is described for the determination of isotype specific antibodies directed to intact Actinobacillus actinomycetemcomitans and bacterial sonicates. Sera from nine individuals, with or without diagnosed periodontal disease, have been examined for IgG antibodies to the microorganism. The conditions for the assay have been studied and the ELISA has been compared to bacterial agglutination, indirect immunofluorescence or passive hemagglutination. A positive correlation is noted among the analyses in separating the sera into high, moderate and low antibody activities. However, based upon the highest dilution of the sera that gave positive reactions in the assays, the modified ELISA is 5–50 fold more sensitive than either the microagglutination, indirect immunofluorescence or passive hemagglutination techniques as performed. The ELISA is a sensitive assay that uses small quantities of biological materials to determine isotype specific antibody levels. This assay can provide a means for rapid screening of large numbers of biological samples for antibodies to intact microorganisms.

    The Banamba slave exodus of 1905 and the decline of slavery in the Western Sudan (1980)
    Cambridge : Cambridge University Press
    The @journal of African history 21 (1980), S. 375-394

    ISSN: 0021-8537

    Topics: History
    Notes: One of the most important changes to take place during the early colonial period was the transformation from slave labour to free labour. In French West Africa this resulted not from a policy decision by the French administration but from the massive departure of slaves in those societies most reliant on slave labour. The focal event was an exodus from Banamba, a Maraka town which had been a major centre both of the slave trade and of the exploitation of slave labour. During the period before the Banamba exodus, tensions were building up within various slave societies, tensions that reflected themselves in a gradual filtering away of slaves and in occasional slave revolts. The French were generally afraid to deal with these tensions and limited themselves to stopping the slave trade while reinforcing allied élites, most of whom were slave owners. There were three major factors in the exodus:(1) Massive enslavement during the late nineteenth century created large reservoirs of slaves who were homogeneous and remembered a free state.(2) The closing-off of recruitment pushed slave-owners to exploit slave labour more systematically.(3) With the end of warfare and the opening of new opportunities in the cities and in the Senegambian peanut fields, slaves had increasing opportunities to go elsewhere.

    EFFECT OF MUSCLE FIBER ANGLE ON WARNER-BRATZLER SHEAR VALUES (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 45 (1980), S. 0

    Notes: Warner-Bratzler shear values were determined on four bovine muscles [longissimus dorsi (LD), psoas major (PM), semitendinosus (ST), and biceps femoris (BF)] such that the muscle fibers were sheared at angles approximating 0°, 45°, and 90° to their longitudinal axis. The extent to which shear values were affected by the angle at which the muscle fibers were sheared was similar for LD, PM, and ST; the difference (approx 2.9 kg) in shear value between muscle fiber angles of 0° and 90° being highly significant (P 〈 0.001). The effect is of sufficient magnitude as to require careful consideration as a source of variation and/or confounding in experiments where treatment effects on Warner-Bratzler shear values are being assessed.

    Disposition of dibekacin in patients undergoing haemodialysis (1980)

    Notes: Summary The pharmacokinetics of Dibekacin were studied in 10 patients with terminal renal impairment (creatinine clearance 〈5 ml/min) undergoing haemodialysis sessions lasting 4 h. The dialyzers were either the Gambro Lundia Major 13.5 or the Ultra Flo II 1.4., and the patients were divided into two groups according to the dialyzer used. Blood flow varied between 250 and 280 ml/min and dialyzate flow between 450 and 600 ml/min. All patients received a single i. v. dose of Dibekacin 1.5 mg/kg at the beginning of the dialysis session. The concentration of the antibiotic at the input and the output of the dialyzer were determined microbiologically by a plate diffusion method usingB. subtilis as the test organism. The intravenously administered antibiotic followed an open two-compartment kinetic model. The type of dialyzer used did not influence the dialysis of Dibekacin. Haemodialysis significantly increased the elimination rate of the antibiotic with respect to the interdialysis periods. The plasma half-life in the slow disposition phase fell from 30 h in the interdialysis period to 4.0 h during dialysis sessions. From the calculated pharmacokinetic parameters, a dosage regimen for this kind of patient is proposed.

    Notes: Abstract Composition of the Nasonov pheromone of the honey bee has been reexamined using new procedures, including analysis of pheromone from single live insects by capillary column GC-MS. Two new components have been identified, nerol and (E,E)-farnesol, and the presence of components proposed previously has been confirmed. Absolute amounts or relative proportions of components in the pheromonal secretion have been determined.
