Dinophysis norvegica is a commonly occurring dinoflagellate species and a producer of diarrhetic shellfish poisons. Natural samples were collected from Trondheim fjord, Norway, to analyse nutrient (O, C, N, P) and toxin (dinophysitoxins [DXTs], okadaic acid [OA], pectenotoxins [PTXs]) content in D. norvegica cells. Nutrient and toxin analyses were also carried out on cells grown under nutrient-suf

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this

This study addressed the contribution of ADAMTS13 deficiency to complement activation in thrombotic thrombocytopenic purpura (TTP). Renal tissue and blood samples were available from 12 TTP patients. C3 and C5b-9 deposition were demonstrated in the renal cortex of two TTP patients, by immunofluorescence and immunohistochemistry, respectively. C3 was also demonstrated in the glomeruli of Shiga toxi

Prospective cohort studies about cutaneous melanoma (CM) risk are still few. Host factor- and UVR exposure data were collected prospectively by questionnaire in this population-based cohort study including 40000 Swedish born women, aged 25-64 years at enrolment (1990). Risk for CM (Cox regression and Stepwise Cox regression [SCR], hazard ratios [HRs] with 95 % Confidence Intervals [CI]) in relatio

This paper presents the VLSI design of an energy-efficient, high-throughput soft-input soft-output signal detector for iterative multiple-input multiple-output (MIMO) receiver. The detector is evolved from our previously developed imbalanced fixed complexity sphere decoder and adopts several new algorithm-level techniques to exploit the available a priori information of transmitted bits. More spec

Objective: Conflicting associations between imaging biomarkers and pain in knee osteoarthritis (OA) have been reported. A relation between pain and denuded areas of subchondral bone (dABs) has been suggested and this study explores this relationship further by relating the presence, phenotype, location and size of dABs to different measures of knee pain. Methods: 633 right knees from the Osteoarth

Trace element incorporation into foraminiferal shells (tests) is governed by physical and chemical conditions of the surrounding marine environment, and therefore foraminiferal geochemistry provides a means of palaeo-oceanographic reconstructions. With the availability of high-spatial-resolution instrumentation with high precision, foraminiferal geochemistry has become a major research topic over

Enterohemorrhagic Escherichia coli produce an attaching and effacing lesion upon adhering to the intestinal epithelium. Bacterial factors involved in this histopathology include the intimin adhesin and E. coli secreted proteins (Esps) A and B. In this study we investigated the serum antibody responses to recombinant E. coli O157:H7 intimin, EspA, and EspB by immuno-blotting. Canadian patients with

The cyclicity of Arctic populations of small rodents is a subject with a long history and a large literature (Batzli, 1992) in which the question "What drives the cycle?" has received many answers, among them that the source of the cycle is either rodent interaction with food or the interaction with predators or both. Another question concerns the confinement of the cycle to Arctic conditions. The

Sequential isolates from eight cynomolgus monkeys experimentally infected with Simian immunodeficiency virus (SIVsm, of sooty mangabey origin) were tested for coreceptor use in the human osteosarcoma indicator cell line, GHOST(3), expressing CD4 and one or another of the chemokine receptors CCR3, CCR5, CXCR4, BOB, or the orphan receptor Bonzo. The indicator cell line carries the human immunodefici

Retinitis pigmentosa (RP) is an inherited blinding disease for which there is no treatment available. It is characterized by a progressive and neurodegenerative loss of photoreceptors but the underlying mechanisms are poorly understood. Excessive activation of the enzyme poly(ADP-ribose) polymerase (PARP) has recently been shown to be involved in several neuropathologies. To investigate the possib

BACKGROUND: An increasing incidence of penicillin-resistant Streptococcus pneumoniae (PRP) was detected in Malmo in 1994. OBJECTIVE: To evaluate clonality and factors facilitating the spread of PRP among children in day-care centers (DCCs). METHODS: We used phenotypic and DNA-fingerprinting methods in conjunction with epidemiologic data from the South Swedish Pneumococcal Intervention Project's in

Wireless communication systems are by nature and by regulations limited in bandwidth and are therefore limited in capacity. Services with Quality of Service (QoS) requirements will enforce a more efficient utilisation of the available capacity. This observation motivates the development of schedulers that can deliver the required QoS as well as being resource efficient. In this thesis, we study r

BACKGROUND: In peritoneal dialysis, approximately 40% of the total osmotic ultrafiltration (UF) induced by glucose can be predicted to be due to "free" water transport across aquaporin-1 (APQ-1). Theoretically, it would be possible to assess the fraction of free water transport in the early phase of a hypertonic dwell, when UF rate is high and the relative contribution of Na+ diffusion is low. La

"Lethal midline granuloma" of the upper airways generally encompasses T-cell lymphoma and Wegener's granulomatosis in Western populations. Treatment and outcome for each is different, but their pathological distinction may not always be possible on routine biopsy specimens. Within a defined population between 1947 and 1994, we found 12 cases of primary sinonasal T-cell lymphoma, all with a CD20-,

This paper discusses five major parameters in desalination, namely technology, raw-water, energy sources, cost and environmental effects. Both size and yield have grown rapidly in desalination plants due to high performance in technology developments in the last few years. Five different types of desalination technology are presented and bench-marked for long-term use: multistage flash evaporation

Popular Abstract in Swedish Blåsexstrofi är en ovanlig och mångfasetterad missbildning. I hela Sverige föds cirka tre barn om året med blåsexstrofi. Bukvägg och urinblåsa är öppna nedanför naveln, så att man ser blåsans insida samt rinnande urin. Flickorna har en delad clitoris, framflyttad och trång slidöppning samt framflyttad ändtarmsöppning. Pojkarna har en kort, öppen penis, som ligger uppfälBladder exstrophy is a complex malformation seen in 1/30 000. Most children are subject to repeated operations, including pelvic osteotomy, genital and bladder neck reconstruction and sometimes bladder augmentation or a urinary reservoir, to achieve continence and a normal genital function. A retrospective study of all Swedish children born 1970-89 showed a low continence rate, 17% , and a high r

Who can pick a winner? Since 1974, various types of targeted support have at different times been directed at the development of the heat pump market in Sweden – which in the following decades oscillated violently between soaring sales and collapse. Eventually, however, small heat pumps for space heating of residential buildings have in recent years securely established themselves as a mature and

Popular Abstract in Swedish Extern fixation är en metod för skelettfixation där perkutana pinnar och/eller vajrar fästes i skelettet och fixeras i en yttre metallram. Extern fixation används alltmer vid frakturläkning och förlängning/korrektion av deformiteter. En extern fixation ger stabilitet åt frakturer och osteotomier och möjlighet till gradvis förlängning/korrektion av deformiteter. BelastniExternal fixation has been more commonly used during the last decades for correction of bone and soft tissue deformities and in frcture healing. The most common complication of external fixation is pin site infection. Two hundred and nineteen younger and/or physically active patients (mean age 53 (18-75) years) suffering from knee osteoarthritis (OA) or knee deformities operated on by hemicallota

In dynamic flexgrid optical networks, the usage of capacity may not be optimal due to the permanent process of setting up and tearing down connections, which, if not controlled, leads to spectrum fragmentation and, as a result, to increase of connection blocking. On top of this, a restoration mechanism that is launched in reaction to a link failure (cable cut) restores the affected lightpaths. Eve
