BACKGROUND: Susceptibility to celiac disease is essentially restricted to carriers of specific HLA DQA1 and DQB1 alleles. We have developed a semi-automated sequence specific primer (SSP) PCR method for clinical HLA typing and compared the test results with those from a commercial method. METHODS: Primers for each DQA1 and DQB1 allele group were included in our PCR-SSP reaction to allow differenti
Idiopathic Scoliosis is a spinal deformity affecting approximately 3% of otherwise healthy children or adolescents. The etiology is still largely unknown but has an important genetic component. Genome-wide association studies (GWAS) have identified a number of common genetic variants that are significantly associated with idiopathic scoliosis in Asian and Caucasian populations, rs11190870 close to
We assessed blood pressure (BP) trends in patients with type 2 diabetes from a national diabetes register using three cross-sectional samples (aged 30-85 years) in 2005, 2007 and 2009, and in patients from 2005 followed individually until 2009. The prevalence of hypertension was 87% among all 180 369 patients in 2009, although lower in subgroups with ages 30-39, 40-49 and 50-59 years: 40%, 60% and
AIMS: Despite a wealth of clinical trial data supporting use of the premixed insulin analogue, biphasic insulin aspart 30 (BIAsp 30) in the treatment of type 2 diabetes mellitus (T2DM), there is limited documentation of its use in primary care-based clinical practice.METHODS: An observational study investigating the safety and efficacy of BIAsp 30 in routine clinical practice was conducted. Patien
OBJECTIVE: To investigate hand problems in patients with systemic lupus erythematosus (SLE) and to explore consequences on the ability to perform daily activities. METHODS: One hundred nine patients with SLE completed a questionnaire assessing hand problems in terms of deficits in body structures, e.g., joints, and body functions including pain, grip force, and other physiologic functions of the h
Aims Patients with a history of atrial fibrillation (AF) have previously been shown to have altered atrial conduction, as seen non-invasively using signal-averaged P-wave analysis. However, little is known about the P-wave morphology in patients in the early phases of AF with structurally normal hearts. Methods and results Thirty-six patients with lone AF were included before the age of 40 years (
The polyamines are polycationic compounds essential for cellular proliferation and transformation. In addition to a well-defined biosynthesis pathway, polyamines are internalized into cells by as yet incompletely defined mechanisms. Numerous reports have shown that efficient polyamine uptake depends on the presence of polyanionic, cell surface-associated heparan sulfate proteoglycans (HSPGs). In t
For the modified Hughes procedure, a tarsoconjunctival flap from the upper eyelid is used to reconstruct large, full-thickness, lower eyelid defects. The conjunctival pedicle is divided once vascularization is deemed to be adequate. The importance of maintaining a flap pedicle to ensure adequate perfusion of the graft has been questioned. The purpose of the study was to investigate the microvascul
In the present study, we hypothesized that changes in perfusion pressure result in altered expression of mRNA and protein encoding for the ETA-, ETB-, AT1- and AT2-receptors in rat mesenteric vessels. Segments of the rat mesenteric artery were cannulated with glass micropipettes, pressurized and luminally perfused in a perfusion chamber. After either exposure to no ("organ culture" (0 mmHg)), norm
Understanding how cells polarize and coordinate tubulogenesis during organ formation is a central question in biology. Tubulogenesis often coincides with cell-lineage specification during organ development. Hence, an elementary question is whether these two processes are independently controlled, or whether proper cell specification depends on formation of tubes. To address these fundamental quest
OBJECTIVE: Statistical analysis is ubiquitous in medical research, but fundamental statistical principles are not always well understood, which has negative effects for both authors and readers of scientific papers. The purpose of this brief review is to provide a methodological overview on populations, samples, analysis units and sampling uncertainty to facilitate an increased understanding of st
In this study, cell nuclei from aneuploid breast cancer samples were sorted with respect to DNA content into pure diploid and aneuploid fractions using flow cytometry. The nuclear proteins were then separated by one-dimensional gel electrophoresis (1D-PAGE) and differences in protein expression patterns, between diploid and aneuploid nuclei from the same tumours, were compared. Using a combination
Positron emission tomography (PET) imaging studies have shown that peak-dose dyskinesia is associated to abnormally high levels of synaptic dopamine (DA) in the caudate-putamen of dyskinetic l-DOPA-treated patients. High striatal extracellular DA levels have also been found in dyskinetic 6-OHDA-lesioned rats as compared to non-dyskinetic ones, suggesting that extracellular DA levels may play a key
Using ethnographic data collected from a Swedish nursing home, this article analyzes residents' everyday or subtle influence attempts relative to the maintenance of institutional routines. Residents' efforts to carve out some autonomy or fulfill personal preferences in everyday matters could be categorized as (1) disruptions, (2) disturbances, or (3) “good matches” relative to ongoing and up-comin
We hypothesized that a low grade in physical education (PE) is associated with an increased risk of future musculoskeletal conditions, especially chronic pain. Using a historical cohort study design, we identified all students (mean age 16.0years), who in 1974-1976 graduated from compulsory school in a Swedish municipality and retrieved their PE grades. We ensured that persons were still alive and
We consider a class of spaces of analytic functions on the unit disc which are Möbius invariant and whose topology is essentially determined by a conformal invariant seminorm. Standard examples of such spaces are the Bloch space. BMOA, the Dirichlet spaces and their recent generalizations ${Cal Q}_K$, which make the object of our interest. We prove a general inequality for the seminorms of dilated
A multi-stage assembly network is considered. A number of end items should be delivered at a certain time. Otherwise a delay cost is incurred. End items and components that are delivered before they are needed will cause holding costs. All operation times are independent stochastic variables. The objective is to choose starting times for different operations in order to minimize the total expected
Purpose: To assess performance of a biomarker-based score that predicts the five-year risk of diabetes (Diabetes Risk Score, DRS) in an independent cohort that included 15-year follow-up. Method: DRS was developed on the Inter99 cohort, and validated on the Botnia cohort. Performance was benchmarked against other risk-assessment tools comparing calibration, time to event analysis, and net reclassi
