This work focus on the functions by which the transcription factor Early B-cell Factor (EBF) regulate gene expression in different cell types. To address this question, gene expression analyses aimed to investigate the regulatory role of EBF in neuroblastoma cells, B-lymphocytes, adipocytes and stromal cells were performed. The addresses question is of crucial importantse for the understanding of
Urban wastewater systems are currently exposed to a major rethink dictated by new demands on resource management. It is postulated that next to providing efficient sanitation (preventing spread of pathogenic microorganisms) these systems should support resource reuse. It remains uncertain of what will be the sanitation of the future; the understanding of technical performances of various alternati

Small bowel carcinoid tumor (SBC) is a rare disease of unknown etiology bill with all age-, sex-, and place-specific occurrence that may indicate an occupational origin. A European multicenter population-based case-control study was conducted from 1995 through 1997. Incident SBC cases between 35 and 69 years of age (n = 101) were identified, together with 3335 controls sampled from the catchment a
Atherosclerosis develops as a result of a chronic arterial inflammation and intimal Fibrosis. The disease represents in many respects a vascular repair process activated in response to injury caused by toxic breakdown products of aggregated and oxidized lipoproteins. The initial response of the artery involves expression of adhesion molecules and recruitment of leukocytes. Degenerated lipoproteins
Due to its unique ability to split water, Photosystem II (PSII) is easily accessible to oxidative damage. Photoinhibited PSII centres diffuse laterally from the grana core region of the thylakoid membrane to the stroma lamellae in order to allow replacement of damaged proteins and cofactors. The 'new born' PSII centres in this region are characterized by the absence of the water splitting capacity
Birds appear to use their tails during flight, but until recently the aerodynamic role that tails fulfil was largely unknown. In recent years delta-wing theory, devised to predict the aerodynamics of high-performance aircraft, has been applied to the tails of birds and has been successful in providing a model for the aerodynamics of a birds tail. This theory now provides the conventional explanati
This thesis presents work within the area of ubiquitous computing, an area based on a vision of computers blending into the background. The work has been done within the EU project PalCom that introduces palpable computing. Palpable computing puts a new perspective on ubiquitous computing, by focusing on human understandability. The thesis goals are to allow for ad-hoc combinations of services an
The problem whether endogenous nitric oxide (NO) may serve as a true physiological regulator of vascular tone in vivo was approached by testing its role during graded acute haemorrhage with the aid of the nitric oxide synthase (NOS) inhibitor L-NAME. The study was performed on the vascular bed of cat skeletal muscle with a technique permitting quantitative recordings of vascular resistance in the
Objective: To determine if the correlation between magnitude of creatine kinase-myocardial band release after coronary artery bypass surgery and 6-month mortality is comparable to that of patients admitted with an acute coronary syndrome. Methods: The GUARDIAN trial tested the efficacy of cariporide, an Na+/H+ exchange inhibitor, on reduction of myocardial ischemia or death in high-risk patients.
Traditional fragmented and mechanistic science is unable to cope with issues about sustainability, as these are often related to complex, self-organizing systems. In the paper, sustainable development is seen as an unending process defined neither by fixed goals nor by specific means of achieving them. It is argued that, in order to understand the sources of and the solutions to modern problems, l
Genetic factors appear to contribute to the severity and progression of diabetic retinopathy. We assessed the associations of the C807T and Glu505Lys variants of the glycoprotein Ia (alpha(2) integrin) subunit of the platelet/endothelial collagen receptor and risk of retinopathy in a population-based survey of 288 diabetic patients in one Swedish community. Neither variant was associated with reti
This thesis analyses educational investments and labour market attachment for refugee immigrants who received a permanent visa to Sweden during 1987-1991. It consists of five self-contained chapters. Chapter 2 presents a brief overview of the historical process behind immigration to Sweden from the post-war period until today, give an orientation on the development of Swedish immigration policy du
The gene encoding calpain-10 (CAPN10) has been identified as a candidate gene for type 2 diabetes. Our aim was to study the impact of genetic (heritability and polymorphisms) and nongenetic (insulin, free fatty acids, and age) factors on CAPN10 mRNA expression in skeletal muscle using two different study designs. Muscle biopsies were obtained before and after hyperinsulinemic-euglycemic clamps fro
Polymorphonuclear leukocyte infiltration into tissues in host defense and inflammatory diseasecauses increased vascular permeability and edema formation through unknown mechanisms.Here, we report the involvement of a paracrine mechanism in neutrophil-evoked alteration inendothelial barrier function. We show that upon neutrophil adhesion to the endothelial lining,leukocytic 2 integrin signaling tri
