Possible Relationship between the HLA-DRA1 Intron Haplotype of Three Single-Nucleotide Polymorphisms in Intron 1 of the HLA-DRA1 Gene and Autoantibodies in Children at Increased Genetic Risk for Autoimmune Type 1 Diabetes

Recently, a haplotype of three single-nucleotide polymorphisms (tri-SNP) in intron 1 of the HLA-DRA1 gene was found to be strongly associated with type 1 diabetes risk in HLA-DR3/3 individuals. The tri-SNP reportedly function as “expression quantitative trait loci,” modulating HLA-DR and -DQ expression. The aim was to investigate HLA-DRA1 tri-SNPs in relation to extended HLA class II haplotypes an

The Influence of Walking Limitations on Daily Life : A Mixed-Methods Study of 14 Persons with Late Effects of Polio

Reduced walking ability is common in persons with late effects of polio (LEoP). Here, we explored how many walking limitations persons with LEoP perceive, and how these limitations influence daily life, by using a mixed-methods design. Fourteen persons (mean age 70 years, whereof 7 women) with LEoP responded to the Walking Impact Scale (Walk-12), and were inter-viewed individually. Qualitative dat

A high intake of dietary fiber influences C-reactive protein and fibrinogen, but not glucose and lipid metabolism, in mildly hypercholesterolemic subjects.

PURPOSE: The aim of the study was to investigate how a diet high in dietary fiber, with several fiber sources included, modulates glucose and lipid metabolism and the inflammatory response in humans. METHODS: Subjects (n = 25) aged 58.6 (1.1) years (mean and SD) with a BMI of 26.6 (0.5) kg/m(2) and a total cholesterol (TC) of 5.8 (0.1) mmol/L (mean and SEM) were given a high fiber (HF) and low fib

Lung Fibroblast Proteoglycan Production Induced by Serum is Inhibited by Budesonide and Formoterol.

Proteoglycans contribute to extracellular matrix remodeling in asthmatic airways. We investigated the effects of budesonide, a glucocorticoid, and formoterol, a long-acting beta(2)-adrenergic agonist, on serum-induced proteoglycan production by human lung fibroblasts. In 10% serum, total proteoglycan production was increased 1.5-fold (P < 0.01) compared with basal production in 0.4% serum. Budeson

Ceylon cinnamon does not affect postprandial plasma glucose or insulin in subjects with impaired glucose tolerance.

Previous studies on healthy subjects have shown that the intake of 6 g Cinnamomum cassia reduces postprandial glucose and that the intake of 3 g C. cassia reduces insulin response, without affecting postprandial glucose concentrations. Coumarin, which may damage the liver, is present in C. cassia, but not in Cinnamomum zeylanicum. The aim of the present study was to study the effect of C. zeylanic

Toward standardization of carbohydrate-deficient transferrin (CDT) measurements: III. Performance of native serum and serum spiked with disialotransferrin proves that harmonization of CDT assays is possible

Carbohydrate-deficient transferrin (CDT) is a generic term that refers to the transferrin glycoforms whose concentration in blood is temporarily increased by sustained alcohol consumption. Due to high clinical specificity, CDT was proposed as a biomarker of heavy alcohol use and has been available for about 20 years. A number of methods have been developed for CDT measurement based on different an

Staphylococcal enterotoxin H - structure and function of a superantigen

Popular Abstract in Swedish I vår omgivning finns det många bakterier, virus och parasiter som kan skada och göra människor sjuka. För att skydda oss mot angrepp av dessa sjukdomsalstrande organismer och andra skadliga ämnen har flera nivåer av skyddsmekanismer utvecklats. Huden, slemhinnorna och det låga pH-värdet i magsäcken är några av de yttre barriärer som hindrar många skadliga organismer atThe aim of this thesis was to characterise the biological functions of the superantigen staphylococcal enterotoxin H (SEH). Superantigens are highly immunostimulatory proteins, which crosslink T cells and antigen presenting cells (APCs). SEH is included in a family of staphylococcal enterotoxins (SEs) produced by certain strains of Staphylococcus aureus. The three-dimensional fold of SEH was dete

Wnt-5a has tumor suppressor activity in thyroid carcinoma

Stabilization of beta-catenin by inhibition of its phosphorylation is characteristic of an activation of the canonical Wnt/beta-catenin signaling pathway and is associated with various human carcinomas. It contrasts to an as yet incompletely characterized action of an alternative noncanonical Wnt signaling pathway on neoplastic transformation. The aim of the present study was to test the effects o

Reduced tonsillar expression of human β-defensin 1, 2 and 3 in allergic rhinitis.

Airway infections are known to cause exacerbations of allergy and asthma. Tonsils constitute a primary site for microbial recognition and triggering of the immune system in the airways. Human β-defensins (HBDs) are antimicrobial peptides with an important role in this defense. Our aim was to investigate HBD1-3 in tonsillar tissue and their potential role in allergic rhinitis (AR). Tonsils, obtaine

Integration and function of new neurons generated from fibroblasts and adult neural stem cells in the pathological brain

In Papers One through Six we have investigated the function and integration of “new” neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. We investigated how the newly generated neuron

Glycosphingolipid composition of epithelial cells isolated along the villus axis of small intestine of a single human individual

A 6-cm fresh proximal ileum surgical specimen from a blood group A(1)Le(a-b+) secretor individual was used for stepwise isolation of epithelial cells from villus tip to crypt bottom by gentle washing with ethylenediaminetetraacetic acid-containing buffer. Acid and non-acid sphingolipids were prepared from the epithelial cell fractions and the non-epithelial intestinal residue. Molecular informatio

Legal stagings. The visualization, medialization and ritualization of law in language, literature, media, art and architecture

In tandem with contemporary modern society becoming increasingly dependent upon visuality, new trends have emerged in cultural studies discussing how visual representations influence our perception of society and its institutions. This is an important observation concerning central elements of law and legal thinking, which to a large extent have been shaped and informed by a text-based tradition:

Effectuation of adaptive stability and postural alignment strategies are decreased by alcohol intoxication.

Human stability control is a complex process comprising contributions from several partly independent mechanisms such as coordination, feedback and feed-forward control, and adaptation. Acute alcohol intoxication impairs these functions and is recognized as a major contributor to fall traumas. The study aimed to investigate how alcohol intoxication at .06% and .10% blood alcohol concentration (BAC

Occurrence of Apoptosis, Secondary Necrosis and Cytolysis in Eosinophilic Nasal Polyps.

The paradigm states that inflammatory cells disappear from airway tissues through apoptosis and phagocytosis. However, cells may also be cleared through primary cytolysis, necrosis secondary to apoptosis, or transepithelial migration. This study examines the occurrence of apoptosis, secondary necrosis, and cytolysis of eosinophils in human nasal polyps in vivo and blood eosinophils in vitro. Eosin

Beta 1 integrin-mediated collagen gel contraction is stimulated by PDGF

The attachment of primary rat hepatocytes and fibroblasts to collagen type I is mediated by non-RGD-dependent beta 1 integrin matrix receptors. In this report we describe a novel 96-well microtiter plate assay for the quantification of fibroblast-mediated contraction of floating collagen type I gels. Fetal calf serum and platelet-derived growth factor (PDGF), but not transforming growth factor-bet

Toward personal eHealth in cardiology. Results from the EPI-MEDICS telemedicine project

The purpose of this study was to develop a method based on artificial neural networks for interpretation of captopril renography tests for the detection of renovascular hypertension caused by renal artery stenosis and to assess the value of different measurements from the test. A total of 250 99mTc-MAG3 captopril renography tests were used in the study. The material was collected from two differen

All histological types of primary human rhabdomyosarcoma express alpha-cardiac and not alpha-skeletal actin messenger RNA

Eleven human primary rhabdomyosarcomas (RMSs), including all histological variants, were analyzed morphologically, immunohistochemically for intermediate filament proteins and actin isoforms, and by means of Northern blots with probes specific for total actin, alpha-skeletal (SK), alpha-cardiac (CARD), and alpha-smooth muscle actin messenger (m)RNAs. All tumors disclosed ultrastructural evidence o

Characterization of specific IgE response in vitro against protein and drug allergens using atopic and normal donors

Background: As the incidence of allergy to different compounds increases in society, the need to understand and characterize specific IgE responses becomes F. obvious. Different cell culture systems have been evaluated for their ability to support such IgE secretion. Methods: One system employed human peripheral lymphocytes (PBL) from normal donors stimulated with anti-CD3 activated T cells with o

Brain mitochondrial function in a murine model of cerebral malaria and the therapeutic effects of rhEPO.

Cerebral malaria (CM) is a life-threatening complication of Plasmodium falciparum infection. The pathogenesis of CM is complex. Cerebral metabolic dysfunction is implicated in CM, which may be caused by both an impaired cerebral microcirculation and a dysregulated inflammatory response affecting cellular respiration of mitochondria. Recombinant human erythropoietin (rhEPO) is a promising new thera

Crepuscular and nocturnal illumination and its effects on color perception by the nocturnal hawkmoth Deilephila elpenor

Recent studies have shown that certain nocturnal insect and vertebrate species have true color vision under nocturnal illumination. Thus, their vision is potentially affected by changes in the spectral quality of twilight and nocturnal illumination, due to the presence or absence of the moon, artificial light pollution and other factors. We investigated this in the following manner. First we measu
