Molecular identification of bloodmeals and species composition in Culicoides biting midges.
Investigations of host preferences in haematophagous insects, including Culicoides biting midges (Diptera: Ceratopogonidae), are critical in order to assess transmission routes of vector-borne diseases. In this study, we collected and morphologically identified 164 blood-engorged Culicoides females caught in both light traps and permanent 12-m high suction traps during 2008-2010 in Sweden. Molecul
Staged proximal deployment of the Zenith TX2 thoracic stent-graft: a novel technique to improve conformance to the aortic arch.
PURPOSE: To present a modification of the Zenith TX2 thoracic stent-graft that allows staged proximal deployment to improve apposition to the aortic wall. TECHNIQUE: Three standard Zenith TX2 thoracic stent-grafts and 3 modified versions were deployed in a glass model of the aortic arch. Deployment sequences were analyzed. In a patient with a 6-cm thoracic aortic aneurysm after a type B dissection

Epidemiology and Prognostic Factors in Acute Superior Mesenteric Artery Occlusion.
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
High NT-proBNP Is a Strong Predictor of Outcome in Elderly Heart Failure Patients.
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,

Control chart analysis of data from a multicenter monitor unit verification study.
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
Cytoskeleton components of inside-out and right-side-out plasma membrane vesicles from plants
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
Isolation and preservation of peripheral blood mononuclear cells for analysis of islet antigen-reactive T cell responses: position statement of the T-Cell Workshop Committee of the Immunology of Diabetes Society.
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 VI Encodes Antimicrobial Activity: Novel Innate Host Defense Properties of the Extracellular Matrix.
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
Thermo-mechanical fatigue crack propagation experiments in Inconel 718
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

Rho-Kinase Signaling Regulates Pulmonary Infiltration of Neutrophils in Abdominal Sepsis via Attenuation of CXC Chemokine Formation and Mac-1 Expression on Neutrophils.
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
The Impact of Tax Reforms Designed to Encourage Healthier Grain Consumption
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
The type 1 diabetes protective HLA DQB1*0602 allele is less frequent in gestational diabetes mellitus.
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
Proteome-based biomarkers in pancreatic cancer.
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

Analyticity and Possible-World Semantics
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 and Transport Systems
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
