Popular Abstract in Swedish År 2008 insjuknade 37 156 personer i akut hjärtinfarkt i Sverige och av dessa dog 10 509 personer. Akut hjärtinfarkt är därmed den vanligaste dödsorsaken i Sverige, men även i resten av världen. Generellt sett insjuknar män ungefär 10 år tidigare än kvinnor i hjärtinfarkt och män har därför en högre total risk att insjukna, även om hjärtinfarkt är den vanligaste dödsorsThe overall aim of this thesis was to explore how the risk for AMI, and the associations between several of its risk factors, differs by gender. Information was collected from four Swedish cohorts: one patient cohort from Skara (1992-1993, n=1149) and three population-based cohorts, i.e. from Skara (1993-1994, n=1109), Vara (2001-2004, n=1811), and Skövde (2003-2005, n=1005). Participants were exa

Biological invasions often cause major perturbations in the environment and are well studied among macroorganisms. Less is known about invasion by free-living microbes. Gonyostomum semen (Raphidophyceae) is a freshwater phytoplankton species that has increased in abundance in Northern Europe since the 1980's and has expanded its habitat range. In this study, we aimed to determine the genetic popul

The recently identified phylogenetic subgroup B5 of fungal glycoside hydrolase family 18 genes encodes enzymes with mannosyl glycoprotein endo-N-acetyl-b-D-glucosaminidase (ENGase)-type activity. Intracellular ENGase activity is associated with the endoplasmic reticulum associated protein degradation pathway (ERAD) of misfolded glycoproteins, although the biological relevance in filamentous fungi

Despite evidence that both pollinators and nonpollinator agents of selection can shape the evolution of floral characters, there have been few attempts to compare the strengths and directions of selection from pollinators and other agents in the same study system. In this investigation of Leucanthemum vulgare, a self-incompatible composite known for its conspicuous white rays, I obtained data from

Background: When the same dose of iodine is given to all patients when performing abdominal computed tomography (CT) there may be a wide inter-individual variation in contrast medium (CM) enhancement of the liver. Purpose: To evaluate if any of the measures body height (BH), body mass index (BMI), lean body mass (LBM), ideal body weight (IBW), and body surface area (BSA) correlated better than bod

Aim: To investigate health-related quality of life (HRQoL) in young persons with limb reduction deficiency (LRD). Methods: One hundred and forty children with LRD aged 8-16 answered the DISABKIDS questionnaire for children with chronic health conditions. Of their parents, 137 answered a corresponding questionnaire concerning their child. Results: Compared to reference data from children with other

Disorders in the musculoskeletal system have been associated with a high physical workload as well as psychosocial and individual factors. It is however not obvious which of these factors that is most important to prevent. Musculoskeletal disorders in neck and upper extremity was assessed by interview and clinical examination in 79 teachers and 93 assisting nurses, all females. Psychosocial work e

Intraneuronal inclusions containing alpha-synuclein (a-syn) constitute one of the pathological hallmarks of Parkinson's disease (PD) and are accompanied by severe neurodegeneration of A9 dopaminergic neurons located in the substantia nigra. Although to a lesser extent, A10 dopaminergic neurons are also affected. Neurodegeneration of other neuronal populations, such as the cholinergic, serotonergic

The overall aim of this thesis was to investigate families’ experiences when a child is diagnosed as having type 1 diabetes, and at one and three years after diagnosis. Since childhood health and the circumstances around it in the family have been shown to have a lasting impact on adult health and circumstances, an additional aim was to examine the long-term effect of childhood diabetes on educati

Calmodulin is a Ca2+-dependent regulatory protein in eukaryotic cells involved in a variety of intracellular activities. Many responses to abiotic stresses involve signaling by Ca2+ and Ca2+/calmodulin regulation, including water and salinity stress. To investigate how calmodulin affects germination on media with high concentrations of NaCl, transgenic tobacco plants expressing heterologous calmod

The prime objective of this study is to investigate if radioluminescence (RL) from carbon-doped aluminum oxide (Al2O3:C) crystals potentially can be used for absorbed dose-rate measurements during proton radiotherapy. The RL from two separate (2 mg) Al2O3:C crystals attached to optical-fiber cables were recorded during irradiations in water in a 175 MeV clinical proton beam. The RL response for lo

OBJECTIVE: To investigate if the preventive measures taken to reduce the occupational exposure to asbestos have resulted in a decreased incidence of pleural mesothelioma in Sweden. METHODS: The incidence of pleural mesothelioma between 1958 and 1995 for birth cohorts born between 1885 and 1964 was investigated. The cases of pleural mesothelioma were identified through the Swedish Cancer Register.

Forty isoniazid-resistant Mycobacterium tuberculosis isolates were characterized on the basis of phenotypic properties (i.e., catalase activity, MIC of isoniazid, and growth pattern in the presence of 7 different concentrations of isoniazid) and alterations in the katG gene (codons 315 and 463). Three different growth patterns could be distinguished: concentration-dependent inhibition of growth wa

The mechanisms involved in the down regulation of the exocrine pancreas are still not fully elucidated. The purpose of the present study was to examine the effect of duodenal and ileal exposure to pancreatic enzymes and bile on pancreatic secretion. Experiments were performed with pigs fitted with pancreatic duct, ileal and jugular vein catheters, and duodenal T-shaped cannula. A negative feedback

In our previous studies we have used electrolytic conductivity detection (ELCD) in the selective analysis of chlorinated fatty acids in marine samples. In order to determine the chlorinated fatty acids quantitatively, we studied the ELCD response factors (RFs) of chlorinated fatty acids and compared them with those of other chlorinated compounds. We also studied the effect of reactor temperature a

Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh

BACKGROUND: Individuals with low income have poorer health and should, therefore, have higher health expenditure than people with high income particularly in countries with a universal health care system. However, it has been discussed if social inequities in health diminish with age and we, hence, aimed to analyse this question. METHODS: We performed an age stratified cross-sectional analysis usi

Background: ABO genotyping is complicated by the remarkable diversity at the ABO locus. Recombination or gene conversion between common alleles may lead to hybrids resulting in unexpected ABO phenotypes. Furthermore, numerous mutations associated with weak subgroups and nondeletional null alleles should be considered. All known ABO genotyping methods, however, risk incorrect phenotype predictions

The first stories about Kluskap, the culture hero of the Mi’kmaq in eastern Canada, were written down at the end of the 19th century. The romantic epoch and the environmental failures of industrialism had generated a growing interest for the “Indian”, who seemed to inherit the continent’s authentic “poetry of the Volk” and harbour deep wisdom about nature. The first written literature about Kluska

Det teoretiska ramverket för studie var GLOBE-studien, Hofstedes fyra dimensioner och Sveningssons och Alvessons förhållningssätt till ledarskap. Syftet var att undersöka den personliga upplevelsen hos Svenska ledare. Fokus var på hur kulturella faktorer påverkade ledarskapet när ledarna arbetade med ett utländskt team. Sex svenska ledare som hade arbetat med utländska team i USA, Indien, TysklandThe theoretical framework of the present study was the GLOBE study, Hofstede’s four dimensions and Sveningsson’s and Alvesson’s approach to leadership. The purpose was to examine the personal experience of Swedish leaders. The focus was on the influence of cultural factors on the leadership when the leaders worked with a foreign team. Six Swedish leaders who had been working with foreign teams in
