A short or otherwise suboptimal neck precludes the use of endovascular repair in 30% to 50% of patients with abdominal aortic aneurysms. Stent-graft fixation in an unsuitable neck carries the risk of technical failure owing to development of a proximal endoleak or stent-graft migration. Furthermore, in some patients, the neck dilates postoperatively. Endovascular healing with tissue incorporation

Substitution of W for the Mo in M2-type Mo-V-Te-oxide was investigated. XRD, FTIR, XANES, and HRTEM verified that the substitution is possible in the whole range up to complete replacement of Mo by W. Catalytic measurements for propene ammoxidation show that both the specific activity and the selectivity to acrylonitrile pass through a maximum with increase of the W-content of the catalyst. XRD an

On, for instance, the miniaturized submersible explorer, Deeper Access, Deeper Understanding (DADU), only 20 cm in length and 5 cm in diameter, the sidescan sonar needs to be tightly mounted in the hull. Finite element analysis (FEA) as well as physical measurements were used to investigate the effects of beam interaction with acoustically nearby rigid boundaries. Computer simulations showed the f

Many mossy fiber pathways to the neurons of the deep cerebellar nucleus (DCN) originate from the spinal motor circuitry. For cutaneously activated spinal neurons, the receptive field is a tag indicating the specific motor function the spinal neuron has. Similarly, the climbing fiber receptive field of the DCN neuron reflects the specific motor output function of the DCN neuron. To explore the rela

Particle formation events were analysed from aerosol number size distribution data collected at a background station in southern Sweden between February 2001 and May 2004. Events occurred on about 36% of all days and were favoured by high global radiation values. The clearest events (class I, 20% of all days) were observed when the formation rate of activated hypothetical clusters around 1 nm diam

The relationship between on the one hand personality traits and, on the other hand, neuropsychological test performance, self-rated distress symptoms, psychosocial work exposure, and social interaction patterns, was studied in a group of healthy women (N= 101). All subjects completed the Karolinska Scales of Personality inventory (KSP) and the majority of the subjects (n = 88) completed the State

Popular Abstract in French Phytoplancton invasif : génétique des populations, phylogéographie, et facteurs facilitant l’invasion par Gonyostomum semen De nos jours, les espèces invasives représentent une importante menace à la biodiversité. Une espèce invasive colonise un nouvel environnement, ou elle était absente, et atteint de forte densité rapidement, diminuant l’abondance ou remplaçant les esnvasive species is a major threat to ecosystems and biodiversity. Invasions by macroorganisms have been intensively studied, but little is known concerning microbial invasions. In aquatic environments, phytoplankton, i.e. autotrophic microbes, have a key role as primary producers. In my thesis, I focused on the population genetic structure and phylogeography of the freshwater raphidophyte Gonyosto

The functional role of herbivores in tropical rainforests remains poorly understood. We quantified the magnitude of, and underlying controls on, carbon, nitrogen and phosphorus cycled by invertebrate herbivory along a 2800m elevational gradient in the tropical Andes spanning 12 degrees C mean annual temperature. We find, firstly, that leaf area loss is greater at warmer sites with lower foliar pho

Aim: The aim of this study was to evaluate the patterns of compliance and the frequency of adenomas and neoplasms in a Swedish population. Methods: In 1996, 2000 men and women born in 1935 or 1936 were selected at random from the population registers of Uppsala and Malmo/Lund. All subjects were invited by mail to participate. In a randomised study design, subjects were either called up by a nurse

The power expenditure of flapping flight in birds is characterised by a U-shaped function of speed through the air. From this relationship and the assumption of limited power available from flight muscles, it is possible to predict changes in the birds' airspeed in relation to external factors such as wind. These predictions are derived from flight mechanical theory and optimality criteria concern

Prophylaxis is defined as the regular administration of clotting factor concentrates to prevent bleeding. Extensive data from observational studies and a recent randomized controlled trial (have established that early prophylactic treatment prevents bleeds and arthropathy in boys with severe haemophilia. The initiation of prophylaxis in young children remains challenging. To prevent arthropathy, p

The vertical transport of tracers by a cumulus ensemble at the TOGA-COARE site is modelled during a 7 day episode using 2-D and 3-D cloud-resolving setups of the Weather Research and Forecast (WRF) model. Lateral boundary conditions (LBC) for tracers, water vapour, and wind are specified and the horizontal advection of trace gases across the lateral domain boundaries is considered. Furthermore, th

In the kindling model of epilepsy, repeated electrical stimulations lead to progressive and permanent intensification of seizure activity. We find that the development of amygdala kindling is markedly retarded in mice heterozygous for a deletion of the neurotrophin-3 (NT-3) gene (NT-3+/- mice). These mice did not reach the fully kindled state (3rd grade 5 seizure) until after 28 +/- 4 days of stim

The aim of this study was to evaluate the usefulness of borrelia serology (Quick ELISA C6 Borrelia assay kit) as a diagnostic tool in cases of suspected neuroborreliosis. A retrospective patient material consisting of 124 paired serum and cerebrospinal fluid samples with a positive anti-borrelia antibody index (AI) using the IDEIA Lyme Neuroborreliosis test was compared with 124 Al-negative matche

BCL11A and BCL11B are transcriptional regulators important for lymphopoiesis and previously associated with hematopoietic malignancies. Ablation of the mouse Bcl11b locus results in failure to generate double-positive thymocytes, implicating a critical role of Bcl11b in T-cell development. However, BCL11B is also expressed in CD4+ T lymphocytes, both in resting and activated states. Here we show b
