INTRODUCTION: Correlation function analysis applied to endocardial electrograms has earlier been used for analysis of agreement between signals and direction of activation during atrial fibrillation (AF). This study was aimed at evaluating whether preferential activation patterns along the coronary sinus (CS) exist in patients with AF. METHODS: Twenty-seven patients (57 ± 10 years old) admitted fo
Titanium dioxide (TiO2) has very high affinity for phosphopeptides and in recent years it has become one of the most popular methods for phosphopeptide enrichment from complex biological samples. Peptide loading onto TiO2 resin in a highly acidic environment in the presence of 2,5-dihydroxybenzoic acid (DHB), phthalic acid, lactic acid, or glycolic acid has been shown to improve selectivity signif
Purpose. To evaluate the retinal function, with emphasis on phenotype and rate of progression, in infants and children with different genotypes of Usher syndrome. Methods. Fourteen children (2-10 years of age) with retinitis pigmentosa and hearing impairment were examined with full-field electroretinography (ERG) during general anesthesia, ophthalmologic examination, and genetic analysis. Five chi
OBJECTIVES: To investigate the incidence and outcomes of acute lower gastrointestinal bleeding (ALGIB) in a population-based setting and examine the role of drugs potentially associated with GIB. METHODS: The study was prospective and population based. The cohort included all patients who underwent colonoscopy during the year 2010 at the National University Hospital of Iceland. Indications for
PURPOSE: Anticipation (ie, an earlier age at onset in successive generations) is linked to repeat expansion in neurodegenerative syndromes, whereas its role in hereditary cancer is unclear. We assessed anticipation in Lynch syndrome (hereditary nonpolyposis colorectal cancer [HNPCC]), in which DNA mismatch repair (MMR) defects cause early and accelerated tumor development with a broad tumor spectr
In this study we have elucidated the effects of allergen-specific antibodies on human DCs and T-cells. Monocyte-derived DCs from allergic patients were exposed to Phlp 5 alone or in complex with Phlp 5-specific human IgG1, IgG4 or IgE and further co-cultured with autologous memory CD4+ T-cells. We demonstrate that DCs treated with Phlp 5/IgE-complexes secrete higher levels of IL-1a, IL-6, VEGF and
We report a population based case-control study of exposure to pesticides as risk factor for non-Hodgkin lymphoma (NHL). Male and female subjects aged 18-74 years living in Sweden were included during December 1, 1999, to April 30, 2002. Controls were selected from the national population registry. Exposure to different agents was assessed by questionnaire. In total 910 (91 %) cases and 1016 (92%)
Proteins affected by anti-mIgM stimulation during B-cell maturation were identified using 2-DE-based proteomics. We investigated the proteome profiles of stimulated and nonstimulated Ramos B-cells at eight time points during 5 d and compared the obtained proteomic data to the corresponding data from DNA-microarray studies. Anti-mIgM stimulation of the cells resulted in significant differences (> o
IgA nephropathy (IgAN) and Henoch-Schönlein purpura (HSP) are diseases characterized by IgA deposits in the kidney and/or skin. Both may arise after upper respiratory tract infections, but the pathogenic mechanisms governing these diseases remain unclear. Patients with IgAN (n = 16) and HSP (n = 17) were included in this study aimed at examining whether IgA-binding M proteins of group A streptococ
Developmental dysplasia of the hip (DDH) is associated with an increased risk of early hip osteoarthritis (OA). We aimed to examine the outcome at the completion of growth in a cohort of children who had residual acetabular dysplasia at age 1 year following early treatment for neonatal instability of the hip (NIH).
PURPOSE: The tyrosine-kinase receptor c-kit and its ligand stem cell factor are coexpressed in many small cell lung cancer (SCLC) cell lines, leading to the hypothesis that this coexpression constitutes an autocrine growth loop. To further evaluate the frequency and pathogenic relevance of c-kit expression, tumor tissue together with the corresponding clinical data of SCLC patients was analyzed. E
For a 12-lead resting electrocardiogram (ECG) to be considered "standard," limb electrodes should be placed distally on the limbs. When resting ECGs are taken in conjunction with an ECG-monitoring situation, so-called monitoring sites (as described by Mason and Likar and also others) on the torso are used. Numerous publication have indicated that these ECGs are not identical with those recorded fr
We present results of numerical experiments that are the one-dimensional analog of positron-hydrogen scattering. The obtained wave functions are exact, within model restrictions.
Introduction: Assessment of hand eczema in a clinical study has been achieved using a scoring system which documents extent of eczema on different areas of the hand. Objective: To investigate whether the same scoring system could be used by patients to communicate actual status of hand eczema. Method: In a study of 62 patients (36 females 26 males, age 18-75), the patient's own assessment was comp
BACKGROUND: recurrent fallers are at especially high risk for injuries. OBJECTIVE: to study whether tests of physical performance are associated with recurrent falls. SUBJECTS: a total of 10,998 men aged 65 years or above. METHODS: questionnaires evaluated falls sustained 12 months preceding testing of grip strength, timed stand, 6-m walk and 20-cm narrow walk test. Means with 95% confidenc
Short review of an anthology, dealing with the influence of surrealism in contemporary film.
α1-antitrypsin (AAT) is a serine protease inhibitor, which recently has been shown to prevent type 1 diabetes (T1D) development, to prolong islet allograft survival and to inhibit β-cell apoptosis in vivo. It has also been reported that T1D patients have significantly lower plasma concentrations of AAT suggesting the potential role of AAT in the pathogenesis of T1D. We have investigated whether pl
AIMS/HYPOTHESIS: Insulin secretion in pancreatic islets is dependent upon mitochondrial function and production of ATP. The transcriptional coactivator peroxisome proliferator activated receptor gamma coactivator-1 alpha (protein PGC-1alpha; gene PPARGC1A) is a master regulator of mitochondrial genes and its expression is decreased and related to impaired oxidative phosphorylation in muscle from p
