Background: The fractalkine/CX3C chemokine receptor 1 (CX3CR1) pathway has been identified to play an essential role in the chemotaxis of microglia, leukocyte trafficking and microglia/macrophage recruitment. It has also been shown to be important in the regulation of the inflammatory response in the early phase after experimental stroke. The present study was performed to investigate if CX3CR1 de

Background: Smoldering multiple myeloma (SMM) is an indolent disease stage, considered to represent the transition phase from the premalignant MGUS (Monoclonal Gammopathy of Undetermined Significance) state towards symptomatic multiple myeloma (MM). Even though this diagnosis provides an opportunity for early intervention, few treatment studies have been done and the current standard of care is ob

The proton-conducting pathway of bacteriorhodopsin (BR) contains at least nine internal water molecules that are thought to be key players in the proton translocation mechanism. Here, we report the results of a multinuclear (1H, 2H, 17O) magnetic relaxation dispersion (MRD) study with the primary goal of determining the rate of exchange of these internal water molecules with bulk water. This rate

Objectives: This study aimed to investigate the effects of adding adjunct mechanical imaging to mammography breast screening. We hypothesized that mechanical imaging could detect increased local pressure caused by both malignant and benign breast lesions and that a pressure threshold for malignancy could be established. The impact of this on breast screening was investigated with regard to reducti

ABHD12 mutations have been linked to neurodegenerative PHARC (polyneuropathy, hearing loss, ataxia, retinitis pigmentosa, and early-onset cataract), a rare, progressive, autosomal, recessive disease. Although ABHD12 is suspected to play a role in the lysophosphatidylserine and/or endocannabinoid pathways, its precise functional role(s) leading to PHARC disease had not previously been characterized

Relatives of cancer patients are at an increased risk of the same (concordant) cancer but whether they are at a risk for different (discordant) cancers is largely unknown - beyond well characterized hereditary cancer syndromes - but would be of major scientific and clinical interest. We therefore decided to resolve the issue by analyzing familial risks when family members were diagnosed with any d

The injury risk for bus passengers is low compared to car users. However, bus passengers also run the risk of sustaining injuries as vulnerable road users: as pedestrians or cyclists to and from the bus stop. Among vulnerable road users, seniors are a particularly important group. Hitherto, injury data have mainly been based on police-reported accidents. These accidents reveal bus occupant safety,

Popular Abstract in Swedish De flesta cancerformer uppvisar förvärvade kromosomavvikelser. En del enklare avvikelser har visat sig förekomma enbart i en viss tumörform och kan därför användas som diagnostiska markörer. I de flesta fall föreligger emellertid ett komplext och ospecifikt avvikelsemönster, ibland med ett mycket kraftigt ökat antal kopior av vissa DNA-sekvenser, så kallad genamplifieriAcquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. The results presented in this thesis demonstrate that the

Semipermeable membrane devices (SPMDs) are passive samplers capable of concentrating hydrophobic chemicals from water, sediments, soil and air. They consist of layflat polymeric membrane such as polyethylene containing a thin film of synthetic lipid such as triolein. The transport of hydrophobic chemicals through the membrane into the lipid is governed by the process of passive diffusion. Therefor

Popular Abstract in Swedish I syfte att upprätthålla en optimal miljö för alla kroppens celler har högre stående djur utvecklat blodcirkulationen genom vilken syre- och andra närings ämnen transporteras till vävnader via artärer och de mindre arteriolerna, medan slaggprodukter förs bort med venerna. Utbytet av näringsämnen och slaggprodukter mellan blod och vävnad sker genom kärlväggen i kroppens Disturbances in microvascular function may be important for tissue damage in many disease states. Prostacyclin, a substance produced by endothelial cells, is important for the maintenance of normal vascular homeostasis and is a potential drug for treatment of microvascular dysfunction, but indications and optimal dosage remains to be established. In the present thesis we evaluated the capillary fi

This paper presents an unbalanced overview of existing Enterprise Resource Planning (ERP) research by reassessing the body of knowledge and emphasising future research directions that need to be pursued in an attempt to fill knowledge gaps and bridge the existing gap between practitioners and academia. To fulfil this objective, nine leading international IS publications covering the period of 2006

Identification of novel biomarkers for early diagnosis, prognosis, and treatment decision will be instrumental for improving disease outcome for patients suffering from complex diseases, such as cancer and autoimmune disorders. Within personalized medicine, the use of circulating biomarkers will allow clinicians to tailor medical treatment based on individual characteristics of each patient, using

Popular Abstract in Swedish Om vi använder allt tillgängligt fossilt bränsle kommer detta leda till att havsnivån ökar med mer än 50 m, enligt nya rön [1]. Även om detta hot ligger långt in i framtiden, finns ett flertal akuta problem kopplade till den globala uppvärminingen. FNs klimatpanel (IPCC) förutspår i sin senaste rapport en stor ökning av torka, skogsbränder, kraftiga orkaner, svält och mTo enable the transition to a green, bio-based economy, an extensive enzymatic toolbox competitive to traditional chemical procedures is needed. One strong area for enzymes is carbohydrate chemistry, due to the over-functionalized nature of carbohydrates, difficult to handle in traditional chemistry. Glycosylation can be catalyzed by four main classes of enzymes, glycosyltransferases, glycoside ph

Aims: This study used nationwide hospital records to examine sibling risk of any type of anxiety disorder in Sweden over a 40-year period. Methods: This study, carried out between 1 January 1968 and 31 December 2007, of the entire population of Sweden, linked information on family relationships from the nationwide Multi-Generation Register with information from the nationwide Swedish Hospital Disc

BACKGROUND: The early detection of circulatory failure in patients with sepsis is important for successful treatment. Heparin-binding protein (HBP), released from activated neutrophils, is a potent inducer of vascular leakage. In this study, we investigated whether plasma levels of HBP could be used as an early diagnostic marker for severe sepsis with hypotension. METHODS: A prospective study of 2

Nucleotide-binding and oligomerization domain (NOD) -like receptors (NLRs) and retinoic acid-inducible gene (RIG) -like receptors (RLRs) are recently discovered cytosolic pattern-recognition receptors sensing mainly bacterial components and viral RNA, respectively. Their importance in various cells and disorders is becoming better understood, but their role in human tonsil-derived T lymphocytes re
