Polyphosphate (polyp) kinase was prepared from EDTA-lysozyme spheroplasts of a Salmonella minnesota rough mutant. The enzyme, purified about 8o-fold, was free of ATPase and polyp-degrading activity and contained neither nucleic acids nor polyp which might act as primer. Using this enzyme, 32P-labelled polyp was prepared from [?P]ATP. The polyp was identified by the action of degrading enzymes, ...

results methylation in at least one gene was reported about 93.8%. the methylation of sfrp2 was reported in 39 out of the 48 subjects (81.2%) whereas methylation of mgmt was observed in 32 subjects (66.6%). conclusions the current study results showed that methylation of sfrp2 and mgmt play an important role in polyp formation. materials and methods forty eight tissue samples of polyp and adeno...

This chapter describes various techniques that can be employed to assist in the removal of colon polyps that are considered to be large or ‘difficult.’ Size alone is only one of the features that may cause some hesitation in making the decision to attempt polyp removal. Other factors that are related to the perceived level of difficulty are polyps that are flat and only slightly elevated above ...

We investigated the cellular mechanisms that led to growth inhibition, morphological changes, and lysis of Bacillus cereus WSBC 10030 when it was challenged with a long-chain polyphosphate (polyP). At a concentration of 0.1% or higher, polyP had a bacteriocidal effect on log-phase cells, in which it induced rapid lysis and reductions in viable cell counts of up to 3 log units. The cellular debr...

Tracheobronchial amyloidosis is one of many causes of endobronchial stenosis and nodularity, the concrete diagnosis of which currently requires the finding of apple-green birefringence from endobronchial biopsies. Bronchoscopic probe-based confocal endomicroscopy (pCLE) is a novel optical biopsy technique which provides real-time images of the lattice structure of the bronchial basement memRece...

Lung separation using a double-lumen endobronchial tube is necessary for video assisted thoracoscopy (VATs). Bronchial rupture after intubation with a double-lumen endobronchial tube has been rarely reported. We report a case of a 70-year-old man who had solitary pulmonary nodule in his right upper lobe. He was intubated with a left-sided Robertshaw double-lumen endobronchial tube. He underwent...

Polyphosphate (polyP) granule biogenesis is an ancient and ubiquitous starvation response in bacteria. Although the ability to make polyP is important for survival during quiescence and resistance to diverse environmental stresses, granule genesis is poorly understood. Using quantitative microscopy at high spatial and temporal resolution, we show that granule genesis in Pseudomonas aeruginosa i...

Polyphosphate (polyP) is a pro-inflammatory agent and a potent modulator of the human blood-clotting system. The presence of polyP of 60 phosphate units was identified in rat basophilic leukemia (RBL-2H3) mast cells using specific enzymatic assays, urea-polyacrylamide gel electrophoresis of cell extracts, and staining of cells with 4,6-diamidino-2-phenylindole (DAPI), and the polyP-binding doma...

background: nasal polyps, a common clinical problem, are characterized by eosinophilic and mast cell inflammation.  the role of allergy and ige in pathogenesis of nasal polyps is still unclear.  ige receptors are important components of the immunological pathway in allergic and inflammatory diseases.   objective: to determine if the low affinity ige receptor (cd23) is presented on nasal polyp t...
