ims In atrial fibrillation (AF), a relation between electrocardiogram (ECG) fibrillatory wave amplitude and thrombus formation has been sought for long with conflicting results. In contrast, the possible relation between atrial fibrillatory rate obtained from the surface ECG and left atrial thrombus formation in patients with AF is unknown and was consequently evaluated in this study. Methods and
A rheological study of mixed micelles formed by PEO-PPO-PEO triblock copolymer P123 and nonionic surfactant C12EO6 in aqueous solutions has been carried out with the purpose of investigating the time dependence of a shape transition of the mixed micelles and characterizing the shape before and after the transition. The rheology results presented in this report give clear evidence that the P123-C12
Fibromuscular dysplasia (FMD) mainly affects renal arteries. Percutaneous transluminal renal angioplasty (PTRA) and surgery are effective treatments, but longtime follow-up is lacking. Retrospective follow-up for 7.0 +/- 4.7 years of 69 consecutive patients ( age 44 +/- 13 years) treated for hypertension due to FMD, 59 patients underwent PTRA and eight patients surgery. In two patients no PTRA was
The paper is based on a general conceptual supply chain flow risk model developed in an earlier paper, a literature review and case studies. The paper has the title "Developing a supply chain risk model" and is reported as a final paper at the NOFOMA 2005 conference. The literature review has been focusing articles and reports/books on supply chain management. Some of its findings have earlier bee
This report focuses on critical metals in Waste from Electrical Electronic Equipment (WEEE) and their recycling possibilities. The criticality is defined in terms of demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy. The report covers assessments of (1) the potential amount of critical metals in the selected product groups, and (2) the actual
Purpose: In one form of human autosomal recessive retinitis pigmentosa and in retinal degeneration (rd1) mouse, mutation occurs in the genes encoding ß subunit of rod photoreceptor cGMP phosphodiesterase. Therefore, rd1 mutant mouse is an appropriate model for human inherited retinal degeneration studies. Retinal explants are successfully cultured in serum free chemically defined R16 medium to eva
Immunoglobulins (Ig), particularly IgE, are believed to be crucially involved in the pathogenesis of asthma and, equally, in allergic models of the disease. To validate this paradigm we examined homozygous mutant C57BL/6 mice, which are B cell deficient, lacking all Ig. Mice were immunized intraperitoneally with 10 micrograms ovalbumin (OVA) plus alum, followed by daily (day 14-20) 30 min exposure
CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc
CONTEXT: Tuberculosis (TB) is an increasing global problem, despite effective drug therapies. Access to TB therapy during conflict situations has not been studied. OBJECTIVE: To determine the effect of irregular TB treatment due to an armed conflict in Guinea-Bissau, West Africa. DESIGN, SETTING, AND PATIENTS: Ongoing retrospective cohort study conducted in the capital city of Bissau among 101 pat
Air samples were collected on glass fibre filters in 22 animal houses and 3 hay storage barns and examined for the presence of bacterial endotoxin with the Limulus (LAL) test and the gas chromatography - tandem mass spectrometry (GC-MSMS) technique, based on detection of 3-hydroxy fatty acids (3-OH-FAs) as chemical markers of the endotoxin lipopolysaccharide. The median concentrations of airborne
The first Scandinavian protocol for Ewing's sarcoma, SSG IV, resulted in a local control rate of 74% and 5-year metastasis-free survival (MFS) of 43%. The second protocol, SSG IX, was started in order to improve upon these results. It featured four chemotherapy cycles, each consisting of two courses of VAI (vincristine, doxorubicin, ifosfamide) alternating with one course of PAI (cisplatin, doxoru
Objective: To explore whether clinical balance and gait tests can predict instability (falls and/or near falls) in people with Parkinson’s disease (PD).Background: Current PD-studies suggest that multiple balance tests should be used in order to predict falls. However, few studies have included near falls when investigating falls prospectively as recommended.Methods: The study included 74 people w
This paper describes the participatory process of developing and implementing a prototype model aimed at supporting the Integrated Sustainability Assessment of water resources and policy options at different scales. The model - called the World Cellular Model (WCM) focuses on the representation of agents’ behaviours and their systemic relationships with their environment. This is achieved by exami
Popular Abstract in Swedish Bioteknik är ett mycket brett ämne som handlar om att använda biologiska reaktioner för att tillverka önskvärda produkter. Det innefattar arbete med mikroorganismer, svampar, enzymer och att få dem att göra som man vill. Enzymer är naturens egna katalysatorer som gör att reaktioner går snabbare utan att själva förbrukas och de är till exempel en viktig del i vår matsmälInterest in sustainable development has increased throughout society during the past decades, and the chemical industry is no exception. The appeal for renewable raw materials has consequently increased and has paved the way for the implementation of industrial biotechnology. Since enzymes are used to convert biomass in nature, they may also be a good choice in the chemical industry. However, to i
From a paradigmatic understanding of tourism, the thing about tourism experiences is that they differ from everyday life. You experience different places, see different people, get to know different ways of doing things, and so on. To do tourism, then, is to experience a series of changes from the ordinary. Several things change in the course of the making and consumption of a tourism product. For
Popular Abstract in English The Andean region and the Amazon Basin of South America have been identified as regions of origin and the domestication of many plants. Some of the food crops from these regions such as potato and cassava, have gained global import¬ance, while the majority of food crops are hardly know outside their present area of cultivation. In the first part of this study, underutiBoth the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. In the first part of the thesis, the composition, crystallinity, degree of branching, morphological, thermal and pasting properties, and susceptibility of the
IMPORTANCE Bipolar disorder is associated with premature mortality, but the specific causes and underlying pathways are unclear. OBJECTIVE To examine the physical health effects of bipolar disorder using outpatient and inpatient data for a national population. DESIGN, SETTING, AND PARTICIPANTS National cohort study of 6 587 036 Swedish adults, including 6618 with bipolar disorder. MAIN OUTCOMES AN
While emissions of many biogenic volatile organic compounds (BVOCs), such as terpenoids, have been studied quite intensively in North American and Scandinavian boreal forests, the vast Siberian boreal forests have remained largely unexplored by experimental emission studies. In this study the shoot-scale terpenoid emission rates from two mature Larix cajanderi trees growing in their natural habita
