Preoperative rectal diclofenac versus paracetamol for tonsillectomy: effects on pain and blood loss

BACKGROUND: Diclofenac is widely used for postoperative analgesia but the perioperative safety of this drug is controversial because of its effect on platelet aggregation, which might increase blood loss. In a prospective investigator-blinded study the effects of diclofenac and paracetamol on pain and blood loss were compared in patients undergoing tonsillectomy. METHOD: Ninety patients were rando

Maintenance plus reliever budesonide/formoterol compared with a higher maintenance dose of budesonide/formoterol plus formoterol as reliever in asthma: an efficacy and cost-effectiveness study

Objective: To evaluate efficacy and cost-effectiveness of budesonide/formoterol (Symbicort*) maintenance (one dose once or twice daily) plus additional doses as needed (Symbicort Maintenance And Reliever Therapy, SMART) compared with a higher fixed dose of budesonide/ formoterol with formoterol as needed in patients with persistent asthma. Study design and methods: 6-month, open, randomised study

Fusion of the SEC31L1 and ALK genes in an inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumor (IMT) is a neoplasm composed of myofibroblastic spindle cells and infiltrating inflammatory cells. Cytogenetic analyses have revealed that a subgroup of IMT, in particular among children and young adults, harbors clonal chromosomal rearrangements involving chromosome band 2p23. Further, molecular genetic studies have shown that these rearrangements target the ALK

Measurement of Bottom Versus Charm as a Function of Transverse Momentum with Electron-Hadron Correlations in p plus p Collisions at s=200 GeV

The momentum distribution of electrons from semileptonic decays of charm and bottom quarks for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV is measured by the PHENIX experiment at the Relativistic Heavy Ion Collider over the transverse momentum range 2 < p(T)< 7 GeV/c. The ratio of the yield of electrons from bottom to that from charm is presented. The ratio is determined using partial D/D

Sequential UV-biological degradation of polycyclic aromatic hydrocarbons in two-phases partitioning bioreactors

A method based on U-V-irradiation in organic solvent followed by transfer of the remaining pollutants into silicone oil for subsequent biodegradation in a biphasic system inoculated with a phenanthrene degrading Pseudomonas sp. was tested for the treatment of various mixtures of PAHs. Acetone was first selected as the most suitable solvent compared to methanol, acetonitrile and silicone oil for th

Residues from transmembrane helices 3 and 5 participate in leukotriene B-4 binding to BLT1

Leukotrienes are inflammatory mediators that bind to seven transmembrane, G-protein-coupled receptors (GPCRs). Here we examine residues from transmembrane helices 3 and 5 of the leukotriene B-4 (LTB4) receptor BLT1 to elucidate how these residues are involved in ligand binding. We have selected these residues on the basis of (1) amino acid sequence analysis, (2) receptor binding and activation stu

Automated PreScan function for scanning fluorescently stained 2D-PAGE gels

To automate the acquisition of images from fluorescently stained gels, the power of the excitation laser(s) must be optimized for each sample to prevent spot saturation (or to allow unimportant spots to saturate) yet still retaining sensitivity. In this work, we describe the implementation and effectiveness of a pre-scan function in a robotic solution for the automation of 2D gel scanning.

Intra- and inter-speaker variations of formant pattern for lateral syllables in Standard Chinese

Speech variation of speakers is a crucial issue for speaker recognition and identification, especially for forensic practice. Greater intra-speaker variation is one main reason for incorrect speaker identification in real forensic situations. Understanding the stability of acoustic parameters and their variation in speech is therefore significant for the evaluation of effective parameters for spea

Cyclometalated Ruthenium(II) Complexes As Efficient Redox Mediators in Peroxidase Catalysis

Cyclometalated ruthenium(II) complexes, [Ru II(C~N)(N~N) 2]PF 6 [HC~N=2-phenylpyridine (Hphpy) or 2-(4'-tolyl)pyridine; N~N=2,2'-bipyridine, 1,10-phenanthroline, or 4,4'-dimethyl-2,2'-bipyridine], are rapidly oxidized by H 2O 2 catalyzed by plant peroxidases to the corresponding Ru III species. The commercial isoenzyme C of horseradish peroxidase (HRP-C) and two recently purified peroxidases from

Vaccination for atherosclerosis: a novel therapeutic paradigm

Numerous studies have identified a role for the innate and adaptive immune response in atherosclerosis; both pro- and antiatherogenic roles for the immune responses have been demonstrated. Common autoantigens against which an immune response has been identified in experimental and human models of atherosclerosis include oxidized low-density lipopoteins, beta2 glycoprotein 1 and heat shock protein

Effects of long term NOS inhibition on disease and the immune system in MOG induced EAE

Hypothesising that systemically and intrathecally produced nitric oxide might play different roles in the EAE pathogenesis, we administered the NOS inhibitor N-nitro-methyl-L-arginine-ester intrathecally or systemically via osmotic minipumps to DA rats with MOG induced EAE. We demonstrate an protective effect of the NOS inhibitor on EAE severity, the extent of CNS inflammation, and demyelination.

Experimental evidence for evaporation/condensation nonuniform flow in a horizontal aerosol generator

The formation of deposition patterns in the cooling zone during operation of a horizontal evaporation/condensation nanoparticle generator was studied to obtain information about flow conditions during particle formation. Quartz reactor tubes were used together with a simple light attenuation measurement to characterize deposition as a function of axial location. Results for the onset and pattern o

Markers for the functional availability of cobalamin/folate and their association with neuropsychiatric symptoms in the elderly

Cobalamin/folate deficiency is common in elderly subjects and may lead to psychiatric symptoms, but even more often it increases the severity of other organic and non-organic mental diseases. This paper reviews the literature relevant for markers of cobalamin/folate status and their relation to neuropsychiatric symptoms in the elderly. Plasma homocysteine, a marker of cobalamin/folate status, is f

An overview of an architecture proposal for a high energy physics grid

This document gives an overview of a Grid testbed architecture proposal for the NorduGrid project [1]. The aim of the project is to establish an inter-Nordic(1) testbed facility for implementation of wide a,rea computing and data handling. The architecture is supposed to define a Grid system suitable for solving data intensive problems at the Large Hadron Collider at CERN [2]. We present the vario

Development and characterization of silane antisticking layers on nickel-based stamps designed for nanoimprint lithography

In this study we will report on the development of a process to establish antisticking layers on nickel-based stamps, which are used in several industrial applications of nanoimprint lithography or related methods. The fluorinated alkyl silane films have been deposited onto different Ni-based stamp surfaces in order to minimize the adhesion tendency at the stamp/polymer interface. film thickness,

An experimental study of gastric stump carcinoma in Wistar rats

The risk of gastric stump carcinoma is increased 15-20 years after gastric resection for benign disease. Reflux of duodenal juice, bacterial overgrowth and formation of N-nitroso compounds are possible etiological factors. There is a geographical variation in the incidence of gastric cancer, possibly explained by differences in food intake. Experimentally it is possible to induce gastric stump car

Gender differences and determinants of aerobic fitness in children aged 8-11 years.

Previous studies of gender differences in maximum oxygen uptake have come to different conclusions. Limited data exists where the determinants of maximum oxygen uptake have been evaluated in a comprehensive manner. Thus, we examined 248 children (140 boys and 108 girls), aged 7.9-11.1 years. Body composition was determined by dual-energy X-ray absorptiometry, measured variables were total body fat
