Consistent aspirin use associated with improved arteriovenous fistula survival among incident hemodialysis patients in the dialysis outcomes and practice patterns study.

Background And Objectives: The relationship between aspirin use and arteriovenous fistula (AVF) survival has been lacking. The aim of this study was to evaluate the association between AVF survival and aspirin use.

Design, Setting, Participants, & Measurements: Data on 2815 incident hemodialysis patients (on dialysis View Article and Find Full Text PDF

Serological classification of Xanthomonas maltophilia (Pseudomonas maltophilia) based on heat-stable O antigens.

Twenty-six serotypes of Xanthomonas maltophilia were defined by using 15 antisera described by Hugh and Ryschenkow (R. Hugh and E. Ryschenkow, J.

Characterization of the binding of and the immune response to pneumococcal group 9 capsular polysaccharides.

The binding of Streptococcus pneumoniae 14C-9N and 14C-9V polysaccharides (PSs) to lymphocytes and polymorphonuclear leukocytes of human blood were studied. The quantity of 14C-9N and 14C-9V PSs bound to leukocytes was proportional to the number of leukocytes and the incubation time; the binding was temperature-dependent. The binding activity appeared to be specific, since the binding was inhibited by prior treatment with homologous group 9 PSs.

Elemental composition of bacterial metachromatic inclusions determined by electron microprobe X-ray analysis.

Electron microscopy and microprobe X-ray analysis were used to study metachromatic inclusions of Spirillum itersonii , Corynebacterium diphtheriae, and Micrococcus luteus. In situ metachromatic inclusions were electron dense and contained phosphorus and divalent cations. Metachromatic inclusions isolated by anion-exchange column chromatography and by isoosmolar Metrizamide density gradient centrifugation were similar in composition to in situ inclusions.

Biochemical variation of Cryptococcus neoformans.

Ninety-seven strains of Cryptococcus neoformans and C. bacillisporus were examined for 44 biochemical characters and the results were analyzed numerically. One phenon emerged at the 86% level of similarity when strains were clustered according to their M-similarity values.

Enhancement of bacterial infections in mice by newcastle disease virus.

This report describes an attempt to define the factors which incite secondary bacterial pneumonias. Groups of mice were given bacteria intraperitoneally and, at various intervals, Newcastle disease virus intravenously. There was an increase in the number of deaths and in the rates of death in these groups, when compared with a control group which was given only bacteria.
