Objectives To determine whether serum vascular endothelial growth factor (s-VEGF) levels and VEGF gene expression in tumor tissue predict survival of diffuse large B-cell lymphoma (DLBCL) patients treated with chemoimmunotherapy. Methods VEGF levels were measured in serum samples from 102 patients <65yrs with high-risk DLBCL using a quantitative sandwich enzyme immunoassay technique. Exon array da
Six-membered cyclic carbonates are potential monomers for aliphatic polycarbonates and polyurethanes in a process without using toxic phosgene and isocyanate. Lipase catalyzed transesterification of the polyol, trimethylolpropane (TMP) with dimethyl carbonate (DMC) or diethyl carbonate (DEC) followed by thermal cyclization was used for synthesis of six-membered cyclic carbonates with pendant hydro
The emergence of automated image analysis algorithms has aided the enumeration, quantification, and immunohistochemical analyses of tumor cells in both whole section and tissue microarray samples. To date, the focus of such algorithms in the breast cancer setting has been on traditional markers in the common invasive ductal carcinoma subtype. Here, we aimed to optimize and validate an automated an
Background. The aim of this study was to compare laparoscopic colposuspension with tension-free vaginal tape (TVT) in terms of costs to the county. Methods. In a prospective, randomized study, we approached 270 consecutive women presenting for evaluation of stress urinary incontinence symptoms at one university hospital. Preoperatively, and at 1-year follow-up, the women underwent urodynamic eval
POU5F1 has two alternatively spliced transcripts: a long (variant 1, NM_002701) and a short (variant 2, NM_203289) transcript. Only variant 1 is a key regulator of pluripotency. Hence, it is important to be able to distinguish this transcript from variant 2 and from the many pseudogenes present in the genome. Previous studies on the expression of POU5F1 were, however, usually carried out without c
In the Western world, consumption of soft drinks has increased the last three decades and is partly responsible for the epidemic-like increase in obesity. Soft drinks, originally sweetened by sucrose, are now sweetened by other caloric sweeteners, such as fructose. In this study, we investigated the short-term effect of sucrose, glucose or fructose solutions on food intake and body weight in rats,
Aim of the study. In this study, we sought to create a model of reversible hyperoxaluria in pigs by feeding with hydroxyproline (HP). Materials and methods. The experiment included 12 pigs divided into 2 groups (n = 6). The pigs were fed twice a day. At the beginning of the experiment, in the adaptation period, all pigs were given standard feed. In the next 7 days, an increasing amount of hydroxyp
Objective: Routine antibiotic treatment of acute uncomplicated diverticulitis (AUD) has been shown ineffective. In this study, the adherence to a new treatment protocol for uncomplicated diverticulitis was evaluated and the incidence of complications in patients treated with and without antibiotics was investigated. Materials and methods: A retrospective study of in-patients diagnosed with AUD at
The aim of this study was to investigate potential dose reductions to the heart, left anterior descending coronary artery (LAD), and ipsilateral lung for left-sided breast cancer using visually guided deep inspiration breath-hold (DIBH) with the optical surface scanning system Catalyst™, and how these potential dosimetric benefits are affected by intrafractional motion in between breath holds. For
Thanks to Bruno Galantucci, “experimental semiotics” is usually nowadays taken to mean the study of “novel forms of communication which people develop when they cannot use pre-established communication systems”. In spite of Galantucci’s claim to have picked the label because it was free, it has actually been used in different ways at least twice before: by Colin Ware, who takes it to be involved w
In this work, we investigated lipid oxidation of cod liver oil during gastrointestinal (GI) digestion using two types of in vitro digestion models. In the first type of model, we used human GI juices, while we used digestive enzymes and bile from porcine origin in the second type of model. Human and porcine models were matched with respect to factors important for lipolysis, using a standardized d
Et af de mest interessante spørgsmål en fysiker kan forsøge at svare på er hvad består tingene af?. Et hus kan skilles ad i mursten, og murstenen kan også skilles ad i sine bestanddele.Sådan kan man fortsætte indtil man bare har atomer tilbage. Atomerne kan skilles ad ielektroner og en atomkerne der består af neutroner og protoner. Elektronen er, så vidt vived, fundamental, og kan ikke skilles ad.This thesis concerns models of high energy collisions of sub-atomic particles, and the models’ implementation in numerical simulations; so–called Monte Carlo event generators. The models put forth in the thesis improves the description of soft collisions of protons, and takes the first steps towards a new, microscopic description of collectivity in proton collisions and collisions of heavy nuclei
Some complex plant-derived polysaccharides, such as modified citrus pectins and galactomannans, have been shown to have promising anti-inflammatory and anti-cancer effects. Most reports propose or claim that these effects are due to interaction of the polysaccharides with galectins because the polysaccharides contain galactose-containing side chains that might bind this class of lectin. However, t
This paper re-focuses the Silk Road discussions from the position of contemporary art in Central Asian region. Since the late 1980s contemporary art in Central Asia boomed and it eventually became an alternative public space for the discussion of cultural transformations, social and global processes and problems that local societies faced. Initially the questions raised by many artists concerned i
Purpose — We wanted to examine the potential of the Scandinavian Sarcoma Group (SSG) Central Register, and evaluate referral and treatment practice for soft-tissue sarcomas in the extremities and trunk wall (STS) in the Nordic countries. Background — Based on incidence rates from the literature, 8,150 (7,000–9,300) cases of STS of the extremity and trunk wall should have been diagnosed in Norway,
FKBP12, a small human enzyme, aids protein folding by catalyzing cis-trans isomerization of peptidyl-prolyl bonds, and is involved in cell signaling pathways, calcium regulation, and the immune response. The underlying molecular mechanisms are not fully understood, but it is well-known that aromatic residues in the active site and neighboring loops are important for substrate binding and catalysis
Pump-probe experiments are commonly used at Free Electron Lasers (FEL) to elucidate the femtosecond dynamics of atoms, molecules, clusters, liquids and solids. Maximizing the signal-to-noise ratio of the measurements is often a primary need of the experiment, and the aggregation of repeated, rapid, scans of the pump-probe delay is preferable to a single long-lasting scan. The limited availability
Organo-metal halide perovskites are some of the most promising materials for the new generation of low-cost photovoltaic and light-emitting devices. Their solution processability is a beneficial trait, although it leads to a spatial inhomogeneity of perovskite films with a variation of the trap state density at the nanoscale. Comprehending their properties using traditional spectroscopy therefore
Recently observed Arctic greening trends from normalized difference vegetation index (NDVI) data suggest that shrub growth is increasing in response to increasing summer temperature. An increase in shrub cover is expected to decrease summer albedo and thus positively feed back to climate warming. However, it is unknown how albedo and NDVI are affected by shrub cover and inter-annual variations in
