BACKGROUND: Reports on trends in incidence and mortality of acute superior mesenteric artery (SMA) occlusion and evaluation of prognostic factors in recent years are lacking. METHODS: Patients with acute SMA occlusion were identified through the in-patient and autopsy registry between 1970 and 1982 (n = 270), 1987 to 1996 (n = 135), and 2000 and 2006 (n = 100) in Malmö, Sweden. RESULTS: The overal
All patients older than 65 years (184 men; mean age, 78+/-0.8 years/181 women; mean age, 82+/-0.6 years) seeking medical attention at the Lund University Hospital Emergency Clinic during a 2-year period who had an N-terminal prohormone brain natriuretic peptide (NT-proBNP) value >2000 pg/mL were followed up for survival. Mortality in the entire population was 21% after 3 months, 35% after 1 year,
BACKGROUND AND PURPOSE: This study aims to investigate the process of monitor unit verification using control charts. Control charts is a key tool within statistical process control (SPC), through which process characteristics can be visualized, usually chronologically with statistically determined limits. MATERIAL AND METHODS: Our group has developed a monitor unit verification software that has
Isolated plasma membrane vesicles purified by aqueous polymer two-phase partitioning were used as a model system for studies on the membrane-associated (cortical) cytoskeleton in plants. Actin, as identified by immunoblotting, was found to be specifically attached to plasma membrane vesicles from cauliflower (Brassica oleracea L.). The actin was not washed off as the vesicles were turned inside-ou
Autoimmune T cell responses directed against insulin-producing β cells are central to the pathogenesis of type 1 diabetes (T1D). Detection of such responses is therefore critical to provide novel biomarkers for T1D 'immune staging' and to understand the mechanisms underlying the disease. While different T cell assays are being developed for these purposes, it is important to optimize and standardi
Collagen type VI is a subepithelial extracellular matrix component in airways and an adhesive substrate for oral pathogens [Bober et al.: J Innate Immun 2010;2:160-166]. Here, we report that collagen VI displays a dose-dependent antimicrobial activity against group A, C, and G streptococci by membrane disruption in physiological conditions. The data disclose previously unrecognized aspects of the
An experimental test facility was developed to perform thermo-mechanical fatigue crack growth experiments. The thermal cycles were generated using hot and cold air flows distributed by a nozzle onto the test specimen. With the equipment it was possible to obtain TMF cycles with cycle times of 120 s with less than 10 °C temperature variation over the measurement length of the sample, cycling betwee
ABSTRACT: Excessive neutrophil infiltration is a major component in septic lung injury, although the signaling mechanisms behind pulmonary recruitment of neutrophils in polymicrobial sepsis remain elusive. Herein, we hypothesized that Rho-kinase activity may play a significant role in pulmonary neutrophil recruitment and tissue damage in abdominal sepsis. Male C57BL/6 mice were treated with the Rh
In this paper, we simulate the effects of tax reforms aimed at encouraging healthier grain consumption. We use a rich data set on household grain consumption in 2003 from the market research institute GfK Sweden, combined with information on the nutritional content of the consumption. We estimate behavioral parameters, which are used to simulate the impact on the average household of tax reforms e
AIMS/HYPOTHESIS: We tested whether gestational diabetes mellitus (GDM) is associated with HLA-DQ genotypes. METHODS: A total of 764 mothers with non-autoimmune (GAD65, insulinoma-associated protein 2 [IA-2] and insulin autoantibody-negative) GDM were ascertained between September 2000 and August 2004 in the population-based Diabetes Prediction in Skåne (DiPiS) study. HLA-DQB1 genotypes were determ
Pancreatic cancer, as a highly malignant cancer and the fourth cause of cancer-related death in world, is characterized by dismal prognosis, due to rapid disease progression, highly invasive tumour phenotype, and resistance to chemotherapy. Despite significant advances in treatment of the disease during the past decade, the survival rate is little improved. A contributory factor to the poor outcom
The aim of this paper is to consider how the notion of analyticity can be dealt with in model-theoretical terms. Standard approaches to possible-world semantics allow us to define necessity and logical truth, but analyticity is considerably more difficult to account for. To explain this difficulty, we first provide a simplified sketch of possible-world semantics. After defining necessity and logic
Ecological economics is an emerging field that offers significant room for creativity and innovation at the conceptual level on how to operationalize sustainability. It integrates economics with ecology and many elements from both the natural and social sciences to provide an integrated perspective on environment-economy interactions. A major policy dilemma that ecological economics addresses is h
BACKGROUND: Social epidemiology investigates both individuals and their collectives. While the limits that define the individual bodies are very apparent, the collective body's geographical or cultural limits (e.g., "neighbourhood") are more difficult to discern. Also, epidemiologists normally investigate causation as changes in group means. However, many variables of interest in epidemiology may
The effect of selenium supplementation of feed on the Se content in bovine milk, whey and plasma, and on the distribution of Se, Zn and Cu in whey and plasma was investigated. In a cross-over study two groups of cows were given a basal feed with 0.16 ppm selenite (approx. 3 mg Se/d) with or without 25 mg yeast Se/d for 2 weeks. In the supplemented group the Se content increased 10-fold in milk, 10
The mechanisms driving the development of immunoglobulin E (IgE) antibody repertoires are a matter of debate. Alternatives to the classical view on antibody development, involving somatic mutation and antigen-driven selection of high-affinity variants in germinal centers, have been proposed. Methods: We have re-analyzed the pattern of mutations in previously isolated and characterized human clonal
Clinical experience over decades and numerous retrospective and, recently, also prospective studies clearly demonstrate that prophylactic treatment, albeit much more expensive, is superior to on-demand treatment regardless of whether the outcome is number of joint- or life-threatening bleeds or arthropathy optimal prophylactic treatment should be started early (primary prophylaxis) but various opi
