Wheat, rye, and barley proteins induce celiac disease, an autoimmune type of gastrointestinal disorder, in genetically susceptible persons. Because the disease may be underdiagnosed, we estimated prevalence tested hypothesis that assays for serum autoantibodies can used to detect untreated positive findings correlate with specific HLA haplotypes.
The fractional quantum Hall effect, being one of the most studied phenomena in condensed matter physics during past thirty years, has generated many groundbreaking new ideas and concepts. Very early on it was realized that zoo emerging states would need to be understood a systematic manner. first attempts do this, by Haldane Halperin, set an agenda for further work which continued this day. Since time idea hierarchies quasiparticles condensing form been pillar our understanding physics. In...
The earliest contact between antigen and the innate immune system is thought to direct subsequent antigen-specific T cell response. We hypothesized that cells of system, such as natural killer (NK) cells, NK1.1+ (NKT cells), γ/δ may regulate development allergic airway disease. demonstrate here depletion (NK NKT cells) before immunization inhibits pulmonary eosinophil CD3+ infiltration well increased levels interleukin (IL)-4, IL-5, IL-12 in bronchoalveolar lavage fluid a murine model...

Serial serum samples groups I II on a gluten-free diet also included. Serum levels antibodies recombinant determined...
Progress in cancer biomarker discovery is dependent on access to high-quality biological materials and high-resolution clinical data from the same cases. To overcome current limitations, a systematic prospective longitudinal sampling of multidisciplinary data, blood tissue patients was therefore initiated 2010 by Uppsala Umeå Universities involving their corresponding University Hospitals, which are referral centers for one third Swedish population.Patients with selected types who treated at...
We present a consistent and unified study of the spectrum low-lying mesons, baryons, glueballs using MIT bag model, incorporating several improvements in model. correct for center-of-mass motion, use running coupling ${\ensuremath{\alpha}}_{s}(R)$, include self-energy terms quarks gluons confined cavity, get constant from model QCD vacuum. Our fit to meson baryon spectrum, including pion, is good predictions glueball are given.

Immunoglobulin (Ig) A against gliadin (AGA-IgA), tissue transglutaminase (tTG-IgA), endomysium (EMA-IgA) analysed.Increased...
Objective. A prominent feature of inflammatory bowel disease (IBD) is the presence cells in gut mucosa, and which contribute to ongoing process. The aim study was evaluate fecal neutrophil, eosinophil, mast cell macrophage markers assessment activity patients with ulcerative colitis (UC). Methods. Twenty‐eight active UC; 4 proctitis, 16 left‐side 8 total colitis, were included study. Patient history, endoscopy histopathology examined serum samples evaluated at inclusion after weeks...
ABSTRACT The role of immunoglobulin A (IgA) anti-tissue transglutaminase antibodies (IgA-tTG) as predictors untreated celiac disease (CoD) is well documented, and the presence levels these are most accurately monitored with native or recombinant human antigens. However, IgA-deficient CoD patients not identified by IgA serology, conflicting results concerning diagnostic validity IgG against gliadin (IgG-AGA), endomysium (IgG-EmA), tTG (IgG-tTG) have been reported. aim present study was to...
We describe a method of analysis which allows for reconstructing the nonlinear disturbance high Q harmonic oscillator. When oscillator is driven with two or more frequencies, nonlinearity causes intermodulation drives, resulting in complicated spectral response. Analysis this spectrum one to approximate nonlinearity. The method, generally applicable measurements based on resonant detection, increases information content measurement without requiring large detection bandwidth, and optimally...
Previous studies have indicated that peripheral circulating markers of inflammation are elevated in women with polycystic ovary syndrome (PCOS), but thus far no concerning adipose tissue been published. The aim the study was to investigate whether patients PCOS display increased expression inflammatory tissue. Twenty overweight PCOS, 10 lean and 20 controls had subcutaneous fat biopsies blood samples taken. Adipose levels mRNA were determined by use real-time PCR. Overweight higher relative...
We have reinvestigated the excited state dynamics of cyclohexa-1,3-diene (CHD) with time-resolved photoelectron spectroscopy and fewest switches surface hopping molecular based on linear response time-dependent density functional theory after excitation to lowest lying ππ* (1B) state. The combination both experiment revealed several new results: First, progress one single surface. After an incubation time 35 ± 10 fs state, proceed ground in additional 60 fs, either via a conrotatory...
We exploit the analogy with quantum Hall (QH) system to study weakly interacting bosons in a harmonic trap. For $\ensuremath{\delta}$-function interaction potential ``yrast'' states $L>~N(N\ensuremath{-}1)$ are degenerate, and we show how this can be understood terms of Haldane exclusion statistics. present spectra for four eight particles obtained by numerical algebraic methods, demonstrate more general hard-core lifts degeneracies on yrast line. The exact wave functions $N=4$ compared...

Abstract. Objective. Analysis of antibodies against tissue transglutaminase (tTG) has been shown valuable in the diagnosis coeliac disease (CD) but how quickly serum titres decrease after introduction a gluten‐free diet (GFD) is not known adults. CD well‐recognized disorder amongst general population and many persons try GFD for fairly vague symptoms before they seek medical advice. Therefore, it important to determine time that serologic tests remain predictive GFD. Methods. Sera were taken...
