The main scope of this thesis has been to study and develop new purification methods and also to further develop existing methods for purification to enhance their efficacy. Important parameters in the development of the methods are that they should be suitable for scale-up and possible to be integrated into recovery processes. The studies in this thesis describe that a hydrophobic peptide tag ca
Purpose: Radon is a risk factor for lung cancer and uranium miners are more exposed than the general population. A genome-wide interaction analysis was carried out to identify genomic loci, genes or gene sets that modify the susceptibility to lung cancer given occupational exposure to the radioactive gas radon. Methods: Samples from 28 studies provided by the International Lung Cancer Consortium w
Abstract: Our aim is to study trends in mental ill-health and socioeconomic-related mental health inequalities over time in Sweden. We also make a first attempt at disentangling why we see such a development, by decomposing any changes in terms of changes in selected demographic and socioeconomic characteristics among the population. A secondary aim is to consider how different indicators for mentAbstract: Our aim is to study trends in mental ill-health and socioeconomic-related mental health inequalities over time in Sweden.

Background: The life expectancy of pancreatic cancer patients remains minimal. The disease progression may be influenced by type 2 diabetes (T2D) and inflammatory status, although important gaps persist around their joint effects on disease outcome. The aim of this study was to investigate the clinical significance of the tumour immune microenvironment on pancreatic cancer prognosis in relation to
Background: Atrial fibrillatory cycle length has been considered one of the indices of atrial electrical remodelling during atrial fibrillation (AF), which can be assessed from surface ECG by computer-assisted calculation of atrial fibrillatory rate (AFR). Horses have been suggested as a bona fide model for AF studies since horses too, develop lone AF, however data on AF characteristics in horses
Alzheimer's disease (AD) is pathologically characterized by the accumulation of amyloid-β (Aβ) plaques, neurofibrillary tangles and widespread neuronal loss in the brain. In recent years, blood biomarkers have emerged as a realistic prospect to highlight accumulating pathology for secondary prevention trials. Neurofilament light chain (NfL), a marker of axonal degeneration, is robustly elevated in
Introduction: Identification of suitable candidates for cardioversion currently is not based on individual electrical and mechanical atrial remodeling. Therefore, this study analyzed the meaning of atrial fibrillatory rate obtained from the surface ECG (as a measure of electrical remodeling) and left atrial size (as measure of mechanical remodeling) for prediction of early atrial fibrillation (AF)
Aim. To measure levels of anxiety among people accompanying consumers to the emergency department and to explore how anxiety influences satisfaction with care. Background. When people seek treatment in an emergency department they are often accompanied by a next-of-kin, family member or friend. While the accompanying person plays a vital role in providing psycho-social support to consumers, little
PURPOSE: miRNAs play a prominent role in a variety of physiologic and pathologic biologic processes, including cancer. For rectal cancers, only limited data are available on miRNA expression profiles, whereas the underlying genomic and transcriptomic aberrations have been firmly established. We therefore, aimed to comprehensively map the miRNA expression patterns of this disease. EXPERIMENTAL DE
BACKGROUND: Butterflies of the subtribe Mycalesina have radiated successfully in almost all habitat types in Africa, Madagascar, the Indian subcontinent, Indo-China and Australasia. Studies aimed at understanding the reasons behind the evolutionary success of this spectacular Old World butterfly radiation have been hampered by the lack of a stable phylogeny for the group. Here, we have reconstruct
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Felaktig DNA-reparation av typen mismatch repair (MMR) uppkommer i 15-17% av cancer i tjock- och ändtarm (kolorektalcancer). MMR defekter är av betydelse i tre situationer: • MMR defekta tumörer har en bättre prognos än övrig tjock- och ändtarmscancer, vilket kan användas för att avgöra huruvida en patient skall erbjudas sk. adjuvant Mismatch repair (MMR) deficiency is carcinogenic and can either have somatic/sporadic causes (i.e. epigenetic silencing or somatic inactivation) or hereditary causes (Lynch syndrome due to a germline mutation in one of the MMR genes ¬- MLH1, MSH2, MSH6, PMS2). The identification of MMR defective colon cancer is clinically relevant for diagnostic, prognostic and potentially also for treatment-predi
Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp
Tetra Pak Global Technical Support AB (GTS) is a company within the Tetra Pak group which main task is to supply the whole world with spare parts for all kinds of Tetra Pak machines. GTS supplies about half a million different parts, which demands a large purchase organisation. This thesis deals with the so-called Sourcing purchase, which is a term for purchase of non-forecasted parts that have no
Förändras mikroorganismers ”samhällsstrukturer” över säsongen? Överallt i marken finns det mikroorganismer som servar växterna med näring, både i form av att de hjälper till att ta upp näring och dela med sig av, och genom att de bryter ner dött material och därmed gör näring tillgänglig. Jag har ställt mig frågan om mikroorganismer i jorden varierar i mängd, sammansättning och aktivitet över säAbstract Seasonal variation in microbial community composition was investigated from early spring tillautumn alonga sandy grasslandslope with variation in soil moisture, vegetation composition and nutrient availability.The testedhypotheses were:(1) the microbial community composition will change with theseason,(2) microbial biomassis highestin spring,(3) saprotrophic fungi will be more abundantin
Abstract Manganese is a redox-sensitive trace element that is essential for humans and other organisms in order to develop and maintain health. Through sewage, manganese enters the oceanic environment from variety of anthropogenic sources, both domestic and industrial, and like every chemical, it can cause toxicity when it exceeds certain concentrations. The main objective of present study was to
As mass timber construction gains momentum worldwide, cross-laminated timber (CLT) has emerged as an important material in the built environment. However, the combustible nature of wood presents challenges and fire safety concerns, and a key interest with respect to CLT is the adhesive bond line. CLT is commonly used in ceiling configuration, and current fire stability evaluations rely predominant
This thesis presents a complete digital back-end implementation of a PN-dither least-mean-squares (LMS) background calibration scheme for a 12-bit, 500 MS/s pipeline analog-to-digital converter (ADC). The target converter, designed by a parallel analog project, comprises four 3-bit stages and a 4-bit final flash stage; its actual inter-stage gains depart substantially from their nominal values, re
I Sverige finns det en nödvärnsrätt som ger en person rätt till ansvarsfrihet när denna försvarat sig mot ett brottsligt angrepp på sin person. Denna rätt har dock kritiserats för att vara utformad att fungera bättre i typiskt sett manliga våldssituationer, d.v.s. då en man attackeras av en annan för honom okänd man. Situationer då den fungerar sämre har ansetts vara då kvinnor använt dödligt våldSwedish law contains a right to self-defense which means that a person should not always be held criminal responsible if it uses violence to defend his- or herself against a violent attack from another person. The right to self-defense has however been criticized for being designed to work better in violent situations that are typical for men, i.e. when a man is attacked by another man that is unk
The consumption and production of livestock have a negative impact on the environment and climate. In many Western countries, the consumption is particularly high and it is expected to increase globally. This increase will lead to further pressure on already stressed planetary boundaries. Recently edible insects have been proposed to be an alternative to conventional meat, because they have a lowe
