OBJECTIVE: To compare the rate of ischemic events and intracranial hemorrhage in the long-term follow-up of patients with persistent and transient severe stenosis or occlusion of the internal carotid artery (ICA) due to spontaneous dissection (ICAD). METHODS: One hundred and sixty-one consecutive patients with unilateral ICAD causing severe stenosis or occlusion were examined clinically and by ult
Chronic mesenteric ischaemia is a rare but serious condition, which if untreated may cause death secondary to starvation or bowel infarction. As the symptoms are sometimes unspecific, its diagnosis may be delayed or missed. Although open surgical revascularisation has been the traditional treatment, a review of published reports suggests it to be associated with operative mortality rates of 6-9 pe

We have studied various thermionic processes in a small one-dimensional ring consisting of a metallic wire and an insulator which serves as the potential barrier for the charge carriers in the metallic wire. The ring is not connected to any particle reservoir, but at the two junctions it is attached to two phonon reservoirs with different temperatures. The lengths of both the metallic wire and the
By homology screening using BLAST searches of expressed sequence tags (ESTs), we have found a previously unidentified cDNA encoding a putative seven-transmembrane receptor with highest similarity to the leukotriene B(4) receptor, BLTR. Analysis of calcium flow in transfected cells, along with sequence analysis, revealed that the EST encoded a functionally inactive protein, lacking the segment corr
Popular AbstractI denna avhandling studeras förhållandet mellan människa och djur, i synnerhet människans relation till lantbrukets djur. Med teoretiska perspektiv från socialkonstruktivism och existentiell fenomenologi behandlas frågor om hur djur och nötkreatur (som utgör en fallstudie) framträder i diskurser och hur de ingår i bönders livsvärldar. Utifrån debatterna om belgisk blå, BSE (galna kThis dissertation is concerned with the relationship between humans and animals. In particular, it explores human relations to farm animals, and especially cattle. The empirical and theoretical work is concerned with how animals appear in discourses and how they form part of human life worlds. Three debates about recent animal-related issues are examined: the introduction of the cattle breed Belg
The presence of a specialised dorsal rim area with an ability to detect the e-vector orientation of polarised light is shown for the first time in a nocturnal hymenopteran. The dorsal rim area of the halictid bee Megalopta genalis features a number of characteristic anatomical specialisations including an increased rhabdom diameter and a lack of primary screening pigments. Optically, these special
Objective: To evaluate the impact of four low-glycaemic index (GI) and one high-GI cereal-based evening meals on glucose tolerance at a subsequent standardised breakfast. Design: Wheat kernels, barley kernels, spaghetti, spaghetti with added wheat bran and white wheat bread (WWB) were consumed in the evening in a random order at five different occasions. At the subsequent breakfast, blood glucose,
Popular Abstract in Swedish Gasturbiner har länge varit en ekonimsk och driftsäkert sätt att producera energi. Främst har dom använts för framdrivning av flygplan och production av elektricitet och värme. Dom ständigt ökade kraven på miljöfarliga emissioner har tvingat fram nya metoder för att producera kraft. Nästa generations kraftverk måste ha hög termisk verkningsgrad samt mycket låga emissionGas turbines have served as economically profitable and reliable generators of power for the past few decades, and have mainly been used in simple and combined cycles. The increased restrictions on hazardous emissions and the increased demand for profitability have created new prospects for innovative power cycles. The requirements for these new power cycles are substantially better emissions, hig
A methodology for estimation of the unknown physical parameters in a detailed model for chromatographic processes is proposed. The model describes the concentration of the solute in the mobile phase and considers external/internal mass transfer resistance. The external volume and its mixing effect are also considered. The unknown model parameters estimated are the bed void, the axial dispersion co
Collagen-induced arthritis (CIA) is one of the most commonly used animal models for Rheumatoid arthritis (RA). CIA is induced in susceptible mouse strains after immunization with heterologous type II collagen (CII). In mice of the H-2q haplotype rat CII (rCII) is used whereas in mice of the H-2r haplotype bovine CII is utilized. The broad objective of this thesis was to gain an understanding of th
Wooded pasture and older forest with dead trees, about 10% of an area of 3000 ha in the central part of the parish of Stenbrohult, was inventoried for wood-living beetles in 1985-2002. In the study areas Carl Linnaeus was born in 1707, and he spent his summers there until 1728. All standard methods for finding wood-beetles were used, including many window traps and 170 wood mould samples. As a new
To enhance the performance of gas turbine engines, high top-cycle temperatures are desired. However, the temperature is limited by current materials. To achieve the higher performance, and meanwhile maintain the metal temperatures of the combustors, vanes and blades below the allowable limits, sophisticated cooling techniques, such as impingement cooling, film cooling and convective internal cooli
