To determine whether expression patterns of segmentation genes found in Drosophila melanogaster can be scaled to pattern larger insects, we studied the expression of the Krüppel (Kr) gene in the blowfly Lucilia sericata. Compared with Drosophila Kr, L. sericata Kr showed an unexpected 10% shift of expression towards the anterior pole. Furthermore, expression domains not found in D. melanogaster we

A novel class of tyrosine kinase blockers represented by the tyrphostins AG1295 and AG1296 is described. These compounds inhibit selectively the platelet-derived growth factor (PDGF) receptor kinase and the PDGF-dependent DNA synthesis in Swiss 3T3 cells and in porcine aorta endothelial cells with 50% inhibitory concentrations below 5 and 1 microM, respectively. The PDGF receptor blockers have not

The aim of this qualitative study was to identify and analyse the experiences of Swedish local health authority occupational therapists with regard to their participation in, and the implementation of, research. Data were collected from three focus-group interviews, with five different occupational therapists in each. The interviews were taped and transcribed and thereafter analysed using broad co

In this study, we consider a dynamic demand model for international tourism. The model is used to estimate separate demand functions for hotel and cottage visitors from different countries, with a multivariate structural time series model. Among other things, the estimated models are used to simulate the effects on international tourism demand in Sweden of an increase in the value added tax on typ

BACKGROUND: Type 2 diabetes often displays hyperlipidemia. We examined palmitate effects on pancreatic islet function in relation to FFA receptor GPR40, NO generation, insulin release, and the PPARgamma agonistic thiazolidinedione, rosiglitazone. PRINCIPAL FINDINGS: Rosiglitazone suppressed acute palmitate-stimulated GPR40-transduced PI hydrolysis in HEK293 cells and insulin release from MIN6c cel

Diabetic kidney disease is the leading cause of end-stage renal disease. Genetic factors have been suggested to contribute to its susceptibility. However, results from genetic studies are disappointing possibly because the role of glucose in diabetic kidney disease predisposed by epigenetic mechanisms has not been taken into account. Since thioredoxin-interacting protein (TXNIP) has been shown to

PURPOSE: To evaluate the long-term results of a prospective, longitudinal case series of untreated, traumatic triangular fibrocartilage complex (TFCC) tears found in displaced distal radial fractures. METHODS: Between 1995 and 1997, 51 patients (24 men, 27 women; age, 20-57 y) with a displaced distal radius fracture had wrist arthroscopy to identify associated injuries. Forty-three patients had c

Even though B-lymphocyte development is one of the best understood models for cell differentiation in the hematopoetic system, recent advances in cell sorting and functional genomics has increased this understanding further. This has suggested that already early lymphoid primed multipotent progenitor cells (LMPPs) express low levels of lymphoid restricted transcripts. The expression of these genes

Small and medium sized enterprises (SMEs) play an important role in all economies today and although their individual environmental impact is often limited, their total impact can be said to be significant due to their sheer number. Environmental management is a way to reduce the impact, but the results obtained by implementing ISO 14001 vary. The point of departure for this dissertation is the hy

The wish to see beyond the horizon of the human biological eye is one of the major driving forces in the development of medical imaging technology. This essay discusses the implications technology has on the ability to see, and consequently know, more about the body. Further, the potential of merging art, rehabilitation engineering and medicine to develop and use images specifically designed to cr

Infestation of skin by the parasitic itch mite Sarcoptes scabiei afflicts 300 million people worldwide and there is a need for novel and efficient therapies. We have previously identified a multigene family of serine proteases comprising multiple catalytically inactive members (scabies mite-inactivated protease paralogs (SMIPPs)), which are secreted into the gut of S. scabiei. SMIPPs are located i

This thesis was motivated by contradictory results from previous studies on reading describing foreign language learners in upper secondary school. Methods based upon ideas by Palinscar & Brown, Cooper, Beck et al, and Krashen were tested on approximately 200 students studying Spanish in the first two years of upper secondary school in Sweden. The methods used are called reciprocal reading, k
