Popular Abstract in Swedish Den elektriska aktiviteten i hjärtats förmak vid kroniskt förmaksflimmer Bakgrund: Det mänskliga hjärtmuskeln består av fyra delar som var och en omsluter ett hålrum, vänster och höger förmak samt vänster och höger kammare. Ett hjärtslag, dvs den sammandragning av hjärtmuskeln som pumpar runt blodet i kroppen, utlöses normalt av att en elektrisk impuls bildas i sinuskChronic atrial fibrillation (CAF), with a prevalence progressively increasing with age, is one of the most common cardiac arrhythmias in man and associated with increased morbidity and mortality. Previous studies have shown that, in animals as well as in man, experimental atrial fibrillation is based on different types and dimensions of intra-atrial electrical re-entry. However, there is a lack of

In this study we approach the recent decline in income inequality in Latin America from the perspective of structural change with a focus on the relative performance of the agricultural sector. Our focus is on the underlying forces implied by Kuznets (1965). We zoom in on the relative performance of agriculture in the development process and the rural-urban duality and pay particular attention to

“Is there a Nordic block, complete with a Nordic economic model and a special kind of Nordic welfare? Nordic collective security? Nordic values, Nordic sex, Nordic gloom? Undeniably the Nordic countries—the Scandinavian trio of Sweden, Denmark and Norway, plus Finland on the eastern flank and Iceland far north-west in the Atlantic—have a great many things in common. And undeniably the lure of the

Outage time after extensive blackouts depends very much on the power system restoration process. Power system restoration is a very challenging task to the operator since the situation is so far from normal conditions. This paper proposes a simulation-based tool that determines a feasible sequence of operator actions that restores power system operation. The effect of each candidate switching oper

Popular Abstract in SwedishPopulärmusikens starka ställning idag gör det angeläget för musikvetenskapen att ta dess konstnärliga aspekter på lika stort allvar som ämnet vanligen behandlar konstmusik. Den populära visan lever i en riklig mängd olika former, allt från folkvisor till rockmusik. Ändå är studier sparsamma idag av de sätt ord, ton och röst samverkar på i visan. Denna studie sätter dessa

Purpose of this paper The expression Enhanced Liability refers to clauses in a contract which obligation one of the partners to accept extended liability for future claims payments beyond normal standards of transport law, conventions or national standard terms and conditions for logistics service intermediaries, logistics service providers and carriers. This paper provides explanations and unders

We randomised 46 newly diagnosed patients with chronic myeloid leukaemia (median age 56) to receive dasatinib 100mg QD or imatinib 400mg QD and report outcome as an intention-to-treat analysis with 36months follow-up. Early cytogenetic and molecular responses were superior in the dasatinib group, with a tendency that imatinib patients caught up with time. For instance, MR3.0 was reached at 3months

Popular Abstract in Swedish Växter får energi att växa till och fortplanta sig genom fotosyntes och cellandning. Vid fotosyntesen använder växterna ljusenergin från solen medan vid cellandningen kolföreningar bryts ner för att frigöra den energi som behövs till olika kemiska processerna i cellen. Enzymer är proteiner som katalyserar dessa kemiska processer. För att omvandla ett utgångsämne (t ex sMost cells are crowded with solutes, enzymes, nucleic acids, structural proteins and membranes. Crowding promotes macromolecular interactions and determines major properties of the cellular environment such as viscosity, diffusion and inhomogeneity. Macromolecular interactions that involve enzymes can affect the kinetic and regulatory properties of these, hence the interactions are part of the met

BACKGROUND: The clinically significant antigens of the Duffy (Fy [FY]) blood group system are expressed on the red cell form of the FY glycoprotein, a promiscuous chemokine receptor and also a receptor for malarial parasites. After the cloning of cDNA coding for FY glycoprotein, the molecular basis of the three major alleles (Fya/Fyb/Fy) has been established. Because of the mistyping of the silent

A rapid (6.5 min) and simple one-step magnetic immunoassay (MIA) has been developed for analysis of human urinary albumin in near patient settings. Polyclonal rabbit anti-human albumin was used as a capture antibody and monoclonal mouse anti-human albumin as a detection antibody in a two-site immunometric assay requiring no additional washing procedures. The polyclonal anti-human albumin was conju

Culling techniques have always been a central part of computer graphics, but graphics hardware still lack efficient and flexible support for culling. To improve the situation, we introduce the programmable culling unit, which is as flexible as the fragment program unit and capable of quickly culling entire blocks of fragments. Furthermore, it is very easy for the developer to use the PCU as cullin

As the identification process is based on the unique patterns of the users, biometrics technologies are expected to provide highly secure authentication systems. The existing systems using fingerprints or retina patterns are, however, very vulnerable. One's fingerprints are accessible as soon as the person touches a surface, while a high resolution camera easily captures the retina pattern. Thus,

The survival of the probiotic strains Lactobacillus reuteri ATCC 55730, Lactobacillus acidophilus DSM 20079 and Bifidobacterium bifidum DSM 20456, all of human origin, were investigated in three different oat-based, non-dairy products (Adavena M40, MG20 and G40). The products were fermented by the three strains with and without the presence of a commercial yoghurt culture (V2). Samples were stored

We studied the projection patterns of antennal lobe (AL) interneurones sensitive to plant volatiles and female-produced sex pheromone components in the female moth, Spodoptera littoralis. Ten compounds (eight plant-derived compounds and two sex pheromone components) were singly applied to the antenna and, using intracellular recording and staining techniques, the physiological and morphological ch

BACKGROUND: Electrophoresis of serum samples allows detection of monoclonal gammopathies indicative of multiple myeloma, Waldenstrom macroglobulinemia, monoclonal gammopathy of undetermined significance, and amyloidosis. Present methods of high-resolution agarose gel electrophoresis (HRAGE) and immunofixation electrophoresis (IFE) are manual and labor-intensive. Capillary zone electrophoresis (CZE

Historically, Q-wave myocardial infarction (MI) has been equated with transmural MI. This association have, however, recently been rejected. The endocardial extent of MI is another potential determinant of pathological Q waves, since the first part of the QRS complex where the Q wave appears reflects depolarization of subendocardial myocardium. Therefore, the aim of the present study was to test t
