    Notizen: Combinations of pale, sop, and exudative (PSE) and red, firm. and nonexudative (RFN) semimembranosus muscle were utilized to manufacture chunked and formed, cured pork. Response Surface Methodology was utilized to investigate the effects of soy protein concentrate (SPC), sodium caseinate (SC), and modified food starch (MFS) on bind and texture profile analysis. Fifteen adjunct formulations for five PSE and RFN combinations provided 75 treatments for each of three replications. As CIE L* values of raw muscle increased, protein-protein bind decreased (P〈0.05). MFS, SC, and SPC decreased (P〈0.05) cohesiveness. MFS and SC decreased (P〈0.05) chewiness, and MFS decreased (P〈0.05) hardness. Utilizing these adjuncts demonstrated that MFS improved texture in PSE and RFN pork. This research demonstrated that diluting RFN pork with no more than 25% PSE pork permits the formation of a high quality boneless deli ham roll.

    Notizen: Healthy elderly people tend to have autoantibodies in their sera. These antibodies, not being associated with any clinical manifestation, have been considered as natural autoantibodies. In systemic lupus erythematosus, as well as in rheumatoid arthritis, the presence of autoantibodies characteristic of these diseases (anti-dsDNA and rheumatoid factor, respectively) depends on the endogeneous production of IL-10. The same could hold true for autoantibodies found in healthy elderly individuals. In the present work, the authors analysed whether an increased production of IL-10 contributed to the production of autoantibodies in elderly people. The authors found that there is neither increased in vivo gene expression nor augmented production of IL-10 by peripheral blood mononuclear cells from elderly women even if they do produce autoantibodies. The authors further sought to determine if the production of autoantibodies is inhibited in vitro by adding an anti-IL-10 MoAb to cell cultures and found that it is not. Despite these negative findings of a role for IL-10 in the production of autoantibodies in elderly people, the authors investigated which cells produce IL-10. In so doing they found that intracellular IL-10 expression occurred exclusively in monocytes in young female controls, but in elderly females it involved also CD8+CD3+ large granular cells. These results indicate that autoantibody production in healthy aged individuals is IL-10 independent.

    Beschreibung / Inhaltsverzeichnis: Résumé Des expérimentations dans la nature avecBacillus thuringiensis Berliner, serotype 14, et le nématodeSteinernema feltiae Filipjev (=Neoaplectana feltiae) ont été réalisées contreSimulium ochraceum Walker et d'autres simulies vectrices de l'onchocercose au Mexique.B. thuringiensis a été fortement toxique et a provoqué jusqu'à 100 % de mortalité mais seulement sur de courtes distances dans le courant. L'augmentation des doses n'a pas entraîné d'amélioration. Les taux de mortalité les plus élevés furent obtenus chez les larves des jeunes stades. le traitement du cours d'eau avecS. feltiae n'a pas abouti à une mortalité significative parce que les stades infestants du nématode étaient soit non ingérés, soit lésés lors de l'ingestion par les pièces buccales des larves.
    Notizen: Abstract Field evaluations ofBacillus thuringiensis Berliner serotype 14 and the nematodeSteinernema feltiae Filipjev 1934 (=Neoaplectana carpocapsae) were conducted againstSimulium ocharaceum Walker and other simuliid vectors of onchocerciasis in Mexico.B. thuringiensis was highly toxic, causing up to 100 % larval mortality, but only for short distances downstream. Increased dosage did not enhance downstream carry ofB. thuringiensis. Highest rates of mortality were recorded against early instar larvae. Stream treatment withS. feltiae did not result in significant larval mortality because the infectivestage nematodes were either not ingested or were injured during ingestion by the larval mouthparts.
