Aim. The aim of this paper was to evaluate short-term outcome of the use of endoanchors to secure the primary migrated endograft and additional extender cuffs to the aortic wall in patients with previous failed endovascular aortic aneurysm repair. Methods. Consecutive patients who needed proximal repair of a primary failed endograft due to migration (with or without type IA endoleaks) were treated
Many decisions in the everyday work of the structural engineer are taken under the influence of uncertainties. The degree of uncertainty affects the quality and variability of the outcome of the structural design work. The effect of uncertainties related to knowledge and experience of the structural engineer was studied in a round robin investigation. Despite a relatively well defined task, the re
The Lund SSAMS machine has been in routine operation since 2004. We present results from the last year of operation of the facility. The reference sample IAEA C7 and the "old" oxalic acid, Oxl, were used as secondary standards. As primary standard for calculations the OxII was used. The background and long term stability of the facility are discussed. We also report on the quality of the C-13/C-12
This paper describes the performance evaluation of new Delta E detectors to be used as pre-cell hit detectors in living cell irradiation experiments at the Lund Ion Beam Analysis facility (LIBAF). Using these detectors with a thickness down to 4.15 mu m fabricated at Lund University, an experiment was setup in which Delta E-detectors were used together with a stop E-detector in a telescope system
A ternary Mg2NiH4 hydride was synthesized using method that relies on a relatively short mechanical milling time (one hour) of a 2:1 MgH2-Ni powder mixture followed by sintering at a sufficiently high hydrogen pressure (>85 bar) and temperature (>400 degrees C). The ternary hydride forms in less than 2.5 h (including the milling time) with a yield of similar to 90% as a mixture of two polymorphic
OBJECTIVE:: To investigate the effects of physical exercise during work hours (PE) and reduced work hours (RWH) on direct and indirect costs associated with sickness absence (SA). METHODS:: Sickness absence and related costs at six workplaces, matched and randomized to three conditions (PE, RWH, and referents), were retrieved from company records and/or estimated using salary conversion methods or
Thin-section analysis of votive terracottas from the Etruscan sites Tessennano, Vulci, Tuscania and Tarquinia were made in order to help explaining the manufacturing process of votiv terracottas, with a focus on coice of raw material (clay and temper). The investigation of the material from these four sites has offered an opportunity to study Etruscan handicraft. The study has shown that e.g. that
A synthetic route to lactam analogues of the fungal STAT3 inhibitor galiellalactone is presented. The synthesis involves a one-pot tosylamide amide coupling/intramolecular Michael addition and an introduction of an alpha,beta-unsaturation, regioselectively directed by the tosyl functionality. An iodolactonization of the octahydroindolizine 9 and a re-opening of the lactone were employed for introd
Silver behenate, a salt of the behenic acid, known mostly for its applications in photothermographic imaging and use as a diffraction reference material, was studied by X-ray diffraction under pressures up to 11.4 GPa. Diffraction patterns were collected using a diamond anvil cell and synchrotron radiation at the 1711 beamline (MAXlab, Lund). The variation of the d spacing with pressure is determi
Synthesis gas generated by the gasification of nitrogen-containing hydrocarbons will contain ammonia. This is a catalyst poison and elevated levels of nitrogen oxides (NOX) will be produced if the synthesis gas is combusted. This paper presents a study of the selective oxidation of ammonia in reducing environments. The concept is the same as in traditional selective catalytic reduction, where NOX
Objective: To determine the incidence and clinical significance of neutralizing antibody (NAb) formation in patients with relapsing multiple sclerosis ( MS) who participated in the European Interferon Beta-1a IM Dose-Comparison Study. Methods. Patients were randomized to treatment with interferon beta-1a (IFN beta-1a) 30 mu g or 60 mu g IM once weekly for up to 4 years. Serum samples obtained at b
Cerebrospinal fluid (CSF) levels of tau, beta-amyloid(1-42) and growth-associated protein 43 (GAP-43) were studied in patients with frontotemporal dementia (FTD; n = 17), Alzheimer's disease (AD; n = 60), subcortical white-matter dementia (SWD; n = 24), Parkinson's disease (PD; n = 23) and dysthymia (n = 19) and in age-matched controls (n = 32). CSF-tau was significantly increased only in AD, and
A naturally contaminated sediment was partially extracted with selective supercritical fluid extraction (SFE) to remove a fraction of supposedly bioavailable PCBs from the matrix. Eels (Anguilla anguilla) were cultured in systems with untreated and pre-extracted sediment, respectively, and it was shown that the SFE treatment selectively removed bioavailable PCBs from the sediment, since relative b
Background: The Btk (Bruton's tyrosine kinase) gene has been shown to be mutated in the human immunodeficiency disease, XLA (X-linked agammaglobulinemia). Btk is a member of the Tec family of cytosolic protein tyrosine kinases with distinct functional domains PH, TH, SH3, SH2, and kinase. Mutations have been observed in each of the Btk subdomains in XLA. We have analyzed the Btk gene in six XLA pa
Interpersonal relationships are important factors in mental health. A genetically sensitive design was used to examine associations among marital quality, adequacy of social support, and 2 aspects of positive mental health in a sample of 652 Swedish twin women and their families. There were 3 main findings. First, the covariance between relationships and positive mental health was partially accoun
Wheat bran (WB), produced worldwide in large quantities as a by-product of the wheat milling industry, constitutes a significant underutilized source of sugars. This paper describes various methods of hydrolyzing the abundant polysaccharides in bran to yield a sugar feedstock suitable for fermentation into bioethanol. Firstly, the starch in the bran was released using amylolytic enzymes. The fibro
With only approximately 50 olfactory receptor neurons (ORNs), the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) may have the smallest olfactory system described in adult Neopteran insects. Using single sensillum recordings (SSR) and gas chromatograph-linked SSR, we characterized 4 olfactory sensilla forming a distinct morphological type, which together house approximately 25% of all ORNs.
We investigated the effects of a single course of antenatal betamethasone on neonatal somatic and brain development. On day 20 of gestation, pregnant rats were injected with either with 170 mu g kg(-1) body weight of betamethasone ("clinically-equivalent dose," equivalent to 12 mg twice, 24 hours apart) or half this dose or vehicle. Pups (8-11 animals per experimental group per time-point per gend
Background: Human papilloma virus (HPV) is the major cause of cervical cancer. Use of HPV genotyping in cervical screening programs and for monitoring the effectiveness of HPV vaccination programs requires access to economical, high-throughput technology. Methods: We used the Sequenom MassARRAY platform to develop a high-throughput mass spectrometric (MS) method for detecting 14 specific oncogeni
The activites of ornithine decarboxylase (ODC) and ODC inhibitory protein (ODC-antizyme) were studied in Ehrlich ascites tumor cells, separated according to their position in the cell cycle by centrifugal elutriation. Release and/or synthesis of ODC-antizyme was induced by putrescine treatment. Each mouse received an intraperitoneal injection of 25 moles of putrescine at 0, 1, 2, and 3 hr after tu
