Background: As 13-valent pneumococcal conjugate vaccine (PCV13) is introduced, children who began vaccination with 7-valent pneumococcal conjugate vaccine (PCV7) may complete their vaccination with PCV13. This open-label phase 3 study evaluated immunogenicity and safety of PCV13 in Swedish infants and toddlers previously given 1 or 2 doses of PCV7 during infancy. Methods: Healthy infants previousl
Mucosal tissues contain large numbers of memory CD4(+) T cells that, through T-cell receptor-dependent interactions with antigen-presenting cells, are believed to have a key role in barrier defense and maintenance of tissue integrity. Here we identify a major subset of memory CD4(+) T cells at barrier surfaces that coexpress interleukin-18 receptor alpha (IL-18Rα) and death receptor-3 (DR3), and d
During the process of biomass gasification tars are formed which exit the gasifier in vapor phase. Tar condensation creates problems like fouling and plugging of after-treatment, conversion and end-use equipment. Gasification tars consist mainly of Polycyclic Aromatic Hydrocarbons (PAHs). Former research has shown the possibilities and difficulties of tar conversion by partial combustion. Basic st
The stabilization characteristics and local extinction structures of partially premixed methane/air flames were studied using simultaneous OH-PLIF/PIV techniques, and large eddy simulations employing a two-scalar flamelet model. Partial premixing was made in a mixing chamber comprised of two concentric tubes, where the degree of partial premixing of fuel and air was controlled by varying the mixin
Collagen-induced arthritis (CIA) is a T cell-dependent autoimmune disease that serves as an animal model for human rheumatoid arthritis. CIA can be induced in H-2q mice by a single immunization with the cartilage-specific protein type II collagen (CII). This study has focused on CII immunity and tolerance with respect to the interactions between antigen, antigen-presenting cells and T cells. CIA-r
The molecular epidemiology of HIV-1 in Iceland has not been described so far. Detailed analyses of the dynamics of HIV-1 can give insights for prevention of virus spread. The objective of the current study was to characterize the genetic diversity and transmission dynamics of HIV-1 in Iceland. Partial HIV-1 pol (1020bp) sequences were generated from 230 Icelandic samples, representing 77% of all H
Background Perfluoroalkyl substances (PFASs) are bio-accumulative pollutants, and prenatal exposure to PFASs is believed to impact human foetal development and may have long-term adverse health effects later in life. Additionally, maternal cigarette smoking may be associated with PFAS levels. Foetal exposure has previously been estimated from umbilical cord plasma, but the actual concentration in
In this paper we outline the initial stages of a human centered design process aimed at the design of novel technology (tangible interactive objects) for stroke survivors. We found it useful to support standard methods, such as interviews and focus groups, with a video prototype in order to make the concept of tangible interaction, which was novel to our users, more clear. In addition we carried o
Popular Abstract in Swedish Sedan 1981, då de första fallen av AIDS beskrevs, har 25 miljoner människor dött på grund av att de har blivit smittade av immunbristviruset HIV . Det finns idag mer än 40 miljoner människor som lever med HIV eller AIDS. SIV är apsläktets variant på HIV och orsakar normalt ingen sjukdom hos sina värddjur som är olika afrikanska apor, men då asiatiska apor, t. ex. makakeSimian immunodeficiency virus (SIV) infections in macaques are commonly used as models to study the pathogenesis of human immunodeficiency virus (HIV). Both SIV and HIV normally use the CD4 receptor and an additional coreceptor for cell entry. The most common coreceptors used by HIV are CCR5 and CXCR4. SIV use CCR5 and rarely CXCR4 but may use other coreceptors as alternatives. We have studied vi
Popular Abstract in Swedish Varför skulle det vara mer europeiskt att rösta ja till Euron än vad det är att rösta nej? Varför går det inte att vara både populist och ?god europé? på samma gång? Vad skiljer en illegal invandrare från en vanlig turist? På vilka sätt avviker Europa från andra föreställda gemenskaper som exempelvis nationen? Avhandlingen ?bringing europe down to earth? (ung. ta ner euWhy is it considered more European to vote in the affirmative of the Euro than it is to vote against it? Why is not possible to be a populist and a ?Good European? at the same time? What makes an illegal immigrant different from a tourist? These questions all concern the limits of what it means to be, act and think as Europeans in Europe. In the political process of bringing the nations and people
Popular Abstract in Swedish Denna avhandling hade som målsättning att belysa långtidsförloppet vid primärt Sjögrens syndrom (SS). Studierna är baserade på registret över SS-patienter vid Universitetssjukhuset MAS och de Amerikansk-Europeiska konsensuskriterierna för SS från 2002. Helicobacter pylori (H. pylori) är inte mer prevalent bland SS-patienter än bland kontrollpersoner. Bakteriens förekomThis work was aimed at improving our understanding of the course of primary Sjögren's syndrome (SS). The Malmö SS patient register and the 2002 American-European Consensus Criteria formed the basis of all studies. Helicobacter pylori (H. pylori) was not more prevalent in SS patients or associated with severe glandular or immunological dysfunction. Consequently, our results do not support screenin
In vision-based feedback control systems, the time to obtain sensor information is usually non-negligible, and these systems thereby possess fundamentally different timing behavior compared to standard real-time control applications. For many image-based tracking algorithms, however, it is possible to trade-off the computational time versus the accuracy of the produced position/orientation estimat
This paper examines the response of five prominent Swedish economists, David Davidson, Gustav Cassel, Eli Heckscher, Knut Wicksell and Bertil Ohlin, to John Maynard Keynes’s "The Economic Consequences of the Peace" and to the German reparations in the 1920s. When Keynes’s book appeared, Davidson and Cassel strongly endorsed it. Heckscher also agreed with Keynes – “a bright spot in a time of darkne
As a prototype of genomics-guided precision medicine, individualized thiopurine dosing based on pharmacogenetics is a highly effective way to mitigate hematopoietic toxicity of this class of drugs. Recently, NUDT15 deficiency was identified as a genetic cause of thiopurine toxicity, and NUDT15-informed preemptive dose reduction was quickly adopted in clinical settings. To exhaustively identify pha
Progress with respect to enrichment and separation of native membrane components in complex lipid environments, such as native cell membranes, has so far been very limited. The reason for the slow progress can be related to the lack of efficient means to generate continuous and laterally fluid supported lipid bilayers (SLBs) made from real cell membranes. We show in this work how the edge of a hyd
This study aimed to determine the effects of advanced glycation end products (AGEs) on endothelial cytoskeleton morphology and permeability, and to detect the underlying signaling mechanisms involved in these responses. Cultured endothelial cells (ECs) were exposed to AGE-modified human serum albumin (AGE-HSA), and EC cytoskeletal changes were evaluated by observing fluorescence of F-actin followi
A series of analogs with nitro or serinamide substituents at the C-2'-, C-5'-, or C-C-position of the combretastatin A-4 (CA4) B-ring was synthesized and evaluated for cytotoxic effects against heart endothelioma cells, blood flow reduction to tumors in SCID mice, and as inhibitors of tubulin polymerization. The synthesis of these analogs typically featured a Wittig reaction between a suitably fun
The type and potency of an immune response provoked during vaccination will determine ultimate success in disease prevention. The basis for this response will be the design and implementation of antigen presentation to the immune system. Whereas direct antigen administration will elicit some form of immunological response, a more sophisticated approach would couple the antigen of interest to a vec
We investigate kinetic broadening effects on the length distributions of gold-catalyzed InAs nanowires having different diameters. It is shown that the length distributions acquire bimodal shape when the longest nanowires exceed the diffusion length of indium adatoms on the nanowire sidewalls. Later on, the length distributions recover unimodal shapes. We develop a theoretical model that is capabl
Background: The outlook for patients with esophageal and gastric (EG) cancer remains poor. Hence, there is a compelling need to identify novel treatment strategies and complementary biomarkers. Programmed death ligand 1 (PD-L1) and mismatch repair deficiency (dMMR) are putative biomarkers of response to immune-checkpoint blockade, but their
