Popular Abstract in Swedish I denna avhandling behandlas brosk proteiners roll såsom antigen och tillgänglighet av immunsystemet i artrit. Sex artiklar omfattas, där fyra presenterar nya djur modeller för reumatoid artrit (RA), en visar hur en genetisk störning av ett broskprotein kan förvärra artrit och den sista hur posttransnationell modifiering av kollagen typ II (CII) påverkar T-cells toleranIn this thesis the role of cartilage proteins and their potential as antigen and availability to the immune system in arthritis were investigated. Six papers are included; where four present new animal models for Rheumatoid arthritis (RA), one shows how genetic disorders in cartilage may affect arthritis and the last how posttranslational modification of collagen type II (CII) affects tolerance. P

The majority of microarray studies focus on analysis of gene expression differences between various specimens or conditions. However, the causes of this variability from one cancer to another, from one sample to another and from one gene to another often remain unknown. In this study, we present a systematic procedure for finding genes whose expression levels are altered due to an intrinsic or ext

Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which the 0 cells in the pancreas are destroyed by the body's own immune system. IL12 plays a role in pathological situations, such as septic shock, tissue damage during inflammation, and organ-specific autoimmune diseases. In NOD mice, administration of IL12 induces T1DM and administration of IL12 antagonists prevents T1DM. Linkage and a

Encountering waves overtaking a ship sailing on the ocean may cause instability. Therefore it is of great importance to study the properties of such waves, for example slope, wavelength and amplitude. When making statistics on the properties of overtaking waves, only the waves that are faster than the ship will affect the resulting distribution. Thus the velocity of the individual waves plays an i

The photochemistry of low lying excited states of six different fluorinated bromobenzenes has been investigated by means of femtosecond laser spectroscopy and high level ab initio CASSCF/CASPT2 quantum chemical calculations. The objective of the work was to investigate how and to what extent light substituents, position on the benzene ring and number, would influence the dissociation mechanism of

The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection for benign hyperplasia or cancer of the prostate and compared with that of controls without antibiotic (Group III). Both regiments significantly reduced the frequency of postoperative bacteriuria (p less than 0.01) and of severe infectious com

We report a new set oftheoretical transition probabilities in Y II, obtained using a multiconfiguration relativistic Hartree-Fock method including core polarization. The overall quality of the calculations is assessed by comparisons with new and previous lifetime measurements. In this paper, we report new measurements of five lifetimes in the 4d5p and 5s5p configurations, in the energy range of 32

Wnt5a is a non-canonical Wnt protein that is expressed at elevated levels in inflammatory conditions. Its role in inflammation remains unclear, although it is known that Wnt5a is expressed at a higher level in monocyte-derived myeloid dendritic cells (Mo-mDCs) than in monocytes and macrophages. The function of Wnt5a in dendritic cells (DCs) remains relatively unexplored. Here, we found that under

Structural chromosome rearrangements may result in the exchange of coding or regulatory DNA sequences between genes. Many such gene fusions are strong driver mutations in neoplasia and have provided fundamental insights into the disease mechanisms that are involved in tumorigenesis. The close association between the type of gene fusion and the tumour phenotype makes gene fusions ideal for diagnost

Constitutional aneuploidy is typically caused by a single-event meiotic or early mitotic error. In contrast, somatic aneuploidy, found mainly in neoplastic tissue, is attributed to continuous chromosomal instability. More debated as a cause of aneuploidy is aneuploidy itself; that is, whether aneuploidy per se causes chromosomal instability, for example, in patients with inborn aneuploidy. We have

Local treatment of metastases such as metastasectomy or radiotherapy remains controversial in the treatment of metastatic renal cell carcinoma. To investigate the benefits and harms of various local treatments, we did a systematic review of all types of comparative studies on local treatment of metastases from renal cell carcinoma in any organ. Interventions included metastasectomy, radiotherapy m

New institutional theory has been critizised, for describing institutionalization as a static qualitative state rather than a process. In this paper we provide an extended understanding of the process of institutionalization by replacing the mechanical concept of diffusion by the concept of translation and an analytical model of "trevel of ideas". Analyzing the field material from three cases of t

Because of the stratospheric ozone depletion that took place during the last decades of the past century, the effects of ultraviolet radiation on plants, animals, humans and micro-organisms became intensively studied. In this chapter we describe the role of the ozone layer as a radiation shield and various molecular and organismal effects of ultraviolet radiation, with an emphasis on the UV-B band

The chapter introduces the overriding question of the volume—whether poor countries can catch up—by providing an overview of theories and approaches that have contributed to this discussion. It argues for the importance of introducing to the analysis the role of structural transformation and to acknowledge that the conditions for economic development vary from case to case. Instead of clinging on

Popular Abstract in Swedish Avhandlingen följer den konfliktladdade relationen mellan far och son i Sven Delblancs författarskap och visar hur en lysande berättarkonst växer fram i samspelet mellan minne och fiktion.In 1991, a year before his death, Sven Delblanc published his highly acclaimed autobiography, Livets ax. At the centre of these childhood memories lies the author’s problematic relationship to his father. In view of the attention attracted by Livets ax, it is not surprising that biographical interpretations of Delblanc’s oeuvre have been predominant. It is evident that the writer’s difficult child

BACKGROUND: Pyrazinamide (PZA) is a key drug in the treatment of tuberculosis (TB), including multidrug-resistant TB. Drug susceptibility testing (DST) of Mycobacterium tuberculosis against PZA is not included in the World Health Organization's yearly proficiency testing. There is an increasing need to establish quality control of PZA DST. OBJECTIVE: To evaluate the performance of PZA DST and to i

Helicobacter pylori is a major factor for the development of gastric cancer. The aim of this study was to define serum antibody patterns associated with H. pylori infection in patients with gastric cancer using a Western blot technique. Serum samples collected from 115 patients with gastric cancer and 110 age- and gender-matched patients without gastrointestinal diseases were tested for IgG antibo

Radiative lifetimes of 16 odd levels belonging to the 4d(2)5p configuration of Zr II have been measured using a time-resolved laser-induced fluorescence technique with a single-step excitation process either from the ground state or from metastable levels belonging to the 4d(2)5s and 4d(3) configurations. For 12 levels, there were no previous results available. The new experimental results and the
