Background: Myeloid cells have been associated with physiological and pathological angiogenesis, but their exact functions in these processes remain poorly defined. Monocyte-derived tissue macrophages of the CNS, or microglial cells, invade the mammalian retina before it becomes vascularized. Recent studies correlate the presence of microglia in the developing CNS with vascular network formation,

Objectives: To compare collagenase injections and surgery (fasciectomy) for Dupuytren's contracture (DC) regarding actual total direct treatment costs and short-term outcomes. Design: Retrospective cohort study. Setting: Orthopaedic department of a regional hospital in Sweden. Participants: Patients aged 65 years or older with previously untreated DC of 30 degrees or greater in the metacarpophalan

For the assessment of personal exposure, information about the concentration of pollutants when people are in given indoor environments (occupancy time) are of prime importance. However this kind of data frequently is not reported. The aim of this study was to assess differences in particle characteristics between occupancy time and the total monitoring period, with the latter being the most frequ

Pheromone-based monitoring is a promising new method for assessing the conservation status of many threatened insect species. We examined the versatility and usefulness of pheromone-based monitoring by integrating a pheromone–kairomone trapping system and pitfall trapping system in the monitoring of two saproxylic beetles, the hermit beetle Osmoderma eremita (Coleoptera: Scarabaeidae) and its pred

Popular Abstract in Swedish Forskning om stamceller har fått mycket uppmärksamhet de senaste åren. Mycket av intresset avspeglar möjligheten att använda denna typ av celler som en terapi för att bota olika sjukdomar. En stam cell från hjärnan är en cell som har förmåga att dela sig symmetriskt, varvid två kopior bildas eller asymmetriskt, vilket ger upphov till en ny stam cell samt en progenitorceIn the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). Long-term growth factor-expanded

Popular Abstract in Swedish Inflammatoriska ledsjukdomar, innefattande bl.a. ledgångsreumatism, reumatoid artrit, och ledinflammation vid psoriasis, psoriasisartrit, är vanliga. I västvärlden lider cirka 1 procent av den vuxna befolkningen av reumatoid artrit (RA) medan psoriasisartrit (PsoA) är mindre vanlig. Ett kännetecken för dessa sjukdomar är att de medför en risk att ledernas vävnader brytsThe pathogenesis of inflammatory arthritides include synovial inflammation and joint tissue destruction. Tissue destruction has traditionally been regarded a consequence of inflammation, but recent observations indicate that the processes are not always closely linked and may proceed uncoupled. The ultimate target organs for the destructive process are articular cartilage and bone. This thesis f

Popular Abstract in Swedish Studier av cystatin C's funktion in vitro och in vivo.

In the present thesis molecular genetic methods were used to address different biological and clinical aspects of Philadelphia (Ph) chromosome-positive leukemias and the BCR and ABL genes. In the first study, children with Ph-positive chronic myeloid leukemia (CML) were found to have essentially the same breakpoint locations in BCR as adults, a pattern which differs from the one seen in Ph-positiv

Popular Abstract in Swedish I ben finns tre olika sorters celler, osteoblaster, osteocyter och osteoklaster. Osteoblaster och osteocyter härstammar från stamceller som kallas stödjevävnadens stamceller och svarar för uppbyggnad och upprätthållande av benvävnaden medan osteoklasterna härstammar från de blodbildande stamcellerna och står för nedbrytning av ben. Ben är den enda vävnaden i kroppen som

Osteoporosis is a severe condition in postmenopausal women and a common cause of fracture. Osteoporosis is a complex disease with a strong genetic impact, but susceptibility is determined by many genes with modest effects and environmental factors. Only a handful of genes consistently associated with osteoporosis have been identified so far. Inflammation affects bone metabolism by interfering with

This thesis focuses on the C-terminal G3 region of the large aggregating proteoglycans that are found in complex with hyaluronan in the extracellular matrix. The G3 region contains a C-type lectin domain that binds different extracellular matrix proteins playing an integral role in tissue organization during development and remodeling. Here we affinity purify the proteoglycan aggrecan via one of i

Neurofibromatosis-Noonan syndrome (NFNS) is a rare condition with clinical features of both neurofibromatosis type 1 (NF1) and Noonan syndrome (NS). All three syndromes belong to the RASopathies, which are caused by dysregulation of the RAS-MAPK pathway. The major gene involved in NFNS is NF1, but co-occurring NF1 and PTPN11 mutations in NFNS have been reported. Knowledge about possible involvemen

Mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) are mature CD5(+) B-cell malignancies with different biological/clinical characteristics. We recently reported an association between different prognostic subgroups of CLL (i.e., IGHV mutated and unmutated) and genomic methylation pattern. However, the relationship between DNA methylation and prognostic markers, such as the prolifer

Essential hypertension is a multifactorial disorder and is the main risk factor for renal and cardiovascular complications. The research on the genetics of hypertension has been frustrated by the small predictive value of the discovered genetic variants. The HYPERGENES Project investigated associations between genetic variants and essential hypertension pursuing a 2-stage study by recruiting cases

Background: In several studies, patients with alcohol dependence treated with the opioid antagonist naltrexone have shown fewer relapses to heavy drinking than those receiving placebo. An interaction between the naltrexone effect and the type of psychological therapy has been observed. Methods: A 6-month, double-blind, placebo-controlled, parallel-group study was performed at 10 different investi

The Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ) combines process-based, large-scale representations of terrestrial vegetation dynamics and land-atmosphere carbon and water exchanges in a modular framework. Features include feedback through canopy conductance between photosynthesis and transpiration and interactive coupling between these 'fast' processes and other ecosystem processes in

Widespread lesions of forebrain cholinergic or noradrenergic projections by intraventricular administration of 192 IgG-saporin or 6-hydroxydopamine, respectively, accelerate kindling epileptogenesis. Here we demonstrate both quantitative and qualitative differences between the two lesions in their effects on hippocampal kindling in rats. Epileptogenesis was significantly faster after noradrenergic

The proton-translocating NADH-ubiquinone oxidoreductase (complex I) is the largest and least understood respiratory complex. The intrinsic redox components (FMN and iron-sulfur clusters) reside in the promontory part of the complex. Ubiquinone is the most possible key player in proton-pumping reactions in the membrane part. Here we report the presence of three distinct semiquinone species in compl
