Background: Few studies have investigated the 24-hour symptom profile in patients with COPD or how symptoms during the 24-hour day are inter-related. This observational study assessed the prevalence, severity and relationship between night-time, early morning and daytime COPD symptoms and explored the relationship between 24-hour symptoms and other patient-reported outcomes. Methods: The study enr
Mice genetically deficient in the glucagon receptor (Gcgr(-/-)) show improved glucose tolerance, insulin sensitivity and α-cell hyperplasia. In addition, Gcgr(-/-) mice do not develop diabetes after chemical destruction of β-cells. Since fibroblast growth factor 21 (FGF21) has insulin independent glucose lowering properties we investigated whether FGF21 was contributing to diabetes resistance in i
BACKGROUND: Most colon cancers start with dysregulated Wnt/β-catenin signalling and remain a major therapeutic challenge. Examining whether HAMLET (human α-lactalbumin made lethal to tumour cells) may be used for colon cancer treatment is logical, based on the properties of the complex and its biological context. OBJECTIVE: To investigate if HAMLET can be used for colon cancer treatment and preven
The home environment is a primary context for daily activities, especially among older adults and persons with disabilities. Functional and age-related decline can generate problems in relation to certain environmental features, necessitating modifications or other provisions of support. The determination of appropriate home interventions is best served using a person–environment (P–E) fit approac
Ahlgren AR, Cinthio M, Steen S, Nilsson T, Sjoberg T, Persson HW, Lindstrom K. Longitudinal displacement and intramural shear strain of the porcine carotid artery undergo profound changes in response to catecholamines. Am J Physiol Heart Circ Physiol 302: H1102-H1115, 2012. First published December 23, 2011; doi:10.1152/ajpheart.00470.2011.-The effects of catecholamines on longitudinal displacemen
This study aims to evaluate the direct effects of anthropogenic deforestation on simulated climate at two contrasting periods in the Holocene, similar to 6 and similar to 0.2 k BP in Europe. We apply We apply the Rossby Centre regional climate model RCA3, a regional climate model with 50 km spatial resolution, for both time periods, considering three alternative descriptions of the past vegetation
BACKGROUND: Ciclosporin is used as an immunosuppressant in current clinical practice but recent research implies novel indications for the drug, such as neuro- and cardioprotection. The intravenous formulation currently on the market, Sandimmune(®) Injection (Sandimmune(®)), uses Cremophor(®) EL as emulsifying excipient. Cremophor(®) EL is known to cause hypersensitivity reactions in some patients
Over the last years an expanding family of small RNAs (i.e. microRNAs, siRNAs and piRNAs) was recognized as key players in diverse forms of gene silencing and chromatin organization. Effectors functions of these small RNAs are achieved through ribonucleoprotein (RNP) complexes containing at their center an Argonaute/Piwi protein. Although these proteins and their small RNA-associated machinery can
Abstract in Undetermined The aim of this study was to achieve a method to perform detailed characterization and human exposure studies of nanosized and nanostructured aerosol particles. The source chosen was mild steel, active gas, arc welding fume. The setup consisted of a generation chamber, where welding can be performed, connected to an airtight stainless steel 22 m(3) exposure chamber. Instru
Scand J Caring Sci; 2012 Adaptation to Swedish and further development of the 'Consequences of Screening - Breast Cancer' questionnaire: a multimethod study Rationale: Experiencing a false-positive screening mammography can cause considerable psychosocial distress. The Consequences of Screening - Breast Cancer questionnaire (COS-BC parts 1 and 2), recently developed in Denmark, is the only conditi
Recently two new classes of low-rate codes have been presented. The first class is the super-orthogonal turbo codes (SOTCs) and the second is the maximum free distance (MFD) convolutional codes. In this paper we present an evaluation of the performance vs. arithmetic decoding complexity for these codes and compare them with the previously reported super-orthogonal convolutional codes (SOCCs). For
Experiments on a modern DI Diesel engine were carried out: The engine was fuelled with standard Diesel fuel, RME and a mixture of 85% standard Diesel fuel, 5% RME and 10% higher alcohols under low load conditions (4 bar IMEP). During these experiments, different external EGR levels were applied while the injection timing was chosen in a way to keep the location of 50% heat release constant. Emissi
Climate change is already impacting species around the world. Although most focus has been on the effect of temperature, changes in climatic variables other than temperature are also expected to drive biological change. Current models suggest that ectotherms, such as reptiles, will be strongly affected by climate change; however, data from natural populations are rare. Here, we use extensive data
Popular Abstract in Swedish Små partiklar i form av vätska eller fast material mellan 0.001 till 100 µm i diameter, kan sväva i luften och kallas då aerosolpartiklar. De påverkar direkt på klimatet genom att reflektera solstrålar ut till rymden. Detta gör att vi får ett kallare klimat. Indirekt kan de påverka klimatet genom att verka som kondensationskärnor vid molnbildning. Med detta påverkar de The aim of this work was to study atmospheric aerosols, focusing on the chemical composition, the morphology and the origin of the aerosol in the upper troposphere and lowermost stratosphere. An aerosol sampler was developed for this purpose. A new method for quantitative analysis of the major components of the aerosol, i.e. C, N and O was developed, and methodologies for single-particle analysis
Indolyl substituted pyranyl- and cyclohexenyl molybdenum complexes were synthesised through stereoselective nucleophilic addition of indoles to the corresponding cationic 2H-pyran or cyclohexadiene molybdenum complex. Decomplexation of an allylic molybdneum complex by treatment with iodine gave 1-(4-iodo-2-cyclohexenyl)-1H-indole-3-carbonitrile in high regio-selectivity. A new method for preparati
The deregulation of the European transport market has been a controversial topic, characterised by a lack of facts and figures on the actual impact of the regulations. Given the crucial importance of road freight transportation to European society, and the lack of figures and control of foreign vehicles operating domestically in other countries, the purpose of this paper is to present a novel, inn
The purpose of this work is the enhancement of performance by a new design of monolithic heat exchangers under steady-state operating conditions. Heat transfer phenomena and hydrodynamics have been studied and visualized by computational fluid dynamics (CFD). Further, a simple gas distribution system has been analyzed in purpose to find the best performance of the exchanger. To achieve this, 3D si
