Background: A significant subset of prostate cancer (PC) patients with a castration-resistant form of the disease (CRPC) show primary resistance to androgen receptor (AR)-targeting drugs developed against CRPC. As one explanation could be the expression of constitutively active androgen receptor splice variants (AR-Vs), our current objectives were to study AR-Vs and other AR aberrations to better

I avhandlingen studeras migration i form av anhöriginvandring till Sverige. I fokus ställs parförhållande där parets seriositet prövas av Migrationsverket. Parets väg genom ansökningsprocessen beskrivs liksom den legala ramen kring anhöriginvandring. Vidare tar avhandlingen upp handläggning av anhöriginvandring och vilka föreställningar om anhöriginvandring och seriösa parförhållanden som finns, dImmigration for family reunion makes up about 30-50 per cent of all immigration to Sweden. The present thesis deals with the handling of applications for reunion immigration and with the comprehension of the concept of reunion immigration and of a “serious relationship”, partly by the executing officer/decision maker who apply the law, partly by the individual who is part of the couple relationshi

Ectomycorrhizal fungi form symbiotic associations with tree roots and assist in nutrient-uptake and -cycling in forest ecosystems, thereby constituting a most significant part of the microbial community. The aims of the studies described in this thesis were to evaluate the potential of DNA-based molecular methods in below-ground ectomycorrhizal community studies and to investigate changes in ectom

Gas turbines emissions, NOX in particular, have negative impact on the environment. To limit the emissions gas turbine burners are constantly improved. In this work, a fourth generation SIT (Siemens Industrial Turbomachinery) burner is studied to gain information about the formation of NOX emissions. The gas mixtures for the full burner are limited to natural gas with different nitrogen dilutions.

Popular Abstract in Swedish Bakgrund och syfte med avhandlingen Glutenintolerans, celiaki är en av de vanligaste kroniska sjukdomarna bland barn och innebär att man inte tåler gluten, som är ett protein och finns i vete, råg och korn. Tunntarmen har en veckad slemhinna med fingerlika utskott , tarmludd och hela tarmen har en yta på 250 kvadratmeter, vilket är lika stort som en tennisplan. Den stBackground: The prevalence of celiac disease (CD) is estimated to be around 1%, but most CD cases are undiagnosed. Sweden experienced an epidemic of clinically detected celiac disease in children younger than 2 years of age, partly due to changes in infant feeding practices, were the amount of gluten and age at introduction was changed. However, it was not clear if the increase in clinically detec

A supported liquid membrane (SLM) method for the speciation of chromium has been developed. The method is based on selective extraction and enrichment of anionic Cr(VI) and cationic Cr(III) species in two serially connected SLM units. Methyltricaprylammonium chloride (Aliquat) and di-(2-ethylhexyl) phosphoric acid (DEHPA), respectively were used as the selective extractants in the membrane liquid.

Electronic and structural properties of Sb-induced GaAs(100)(2x4) and (2x8) surfaces are studied by means of core-level and valence-band photoelectron spectroscopy utilizing synchrotron radiation and scanning tunneling microscopy. Combining these results and showing good consistency among them, we demonstrate that the Sb/GaAs(100)(2x4) surface is well compatible with the delta structural model, wh

Background: Patients with ostium secundum atrial septal defects (ASDs) were studied to determine the prevalence of Selvester anteroseptal myocardial infarction QRS points, and to test the hypothesis that there is a relationship between these criteria and thinning and/or scarring of the inter-ventricular septum (IVS). Methods: Demographic, electrocardiographic (ECG), and cardiac magnetic resonance

Objective: Oxygen enhanced pulmonary MRI is a promising modality for functional lung studies and has been applied to a wide range of pulmonary conditions. The purpose of this study was to characterize the oxygen enhancement effect in the lungs of healthy, never-smokers, in light of a previously established relationship between oxygen enhancement and diffusing capacity of carbon monoxide in the lun

We report the transverse energy (ET) measured with ALICE at midrapidity in Pb-Pb collisions at sNN=2.76 TeV as a function of centrality. The transverse energy was measured using identified single-particle tracks. The measurement was cross checked using the electromagnetic calorimeters and the transverse momentum distributions of identified particles previously reported by ALICE. The results are co

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs.

Background: Incisional hernia is one of the most common complications after laparotomy. The aim of this retrospective study was to investigate incidence, location and risk factors for incisional hernia after open resection for colorectal liver metastases including the use of perioperative chemotherapy and targeted therapy evaluated by computed tomography. Methods: Patients operated for colorectal

This study raises the question of how marriage market relevant status characteristics are distributed among partners in exogamous relationships. The status exchange hypothesis posits that partners in racially and ethnically heterogamous relationships trade status characteristics, mainly education. We address this hypothesis focusing on intermarriages between immigrants and native men (N=606,257) a

Flexible multibody dynamics (FMD) has found many applications in control, analysis and design of mechanical systems. FMD together with the theory of structural optimization can be used for designing multibody systems with bodies which are lighter, but stronger. Topology optimization of static structures is an active research topic in structural mechanics. However, the extension to the dynamic case

Abstract: This thesis examines the non-dominant and self-subversive aspects of visuality in Roberto Bolaño’s 2666 through the lens of the philosophical discussion on representation, particularly in its post-structuralist context. The present research is grounded in the conviction that 2666 embodies the 20th-century crisis of representation and approaches the novel through an analysis of different

While workplace physical exercise can help manage musculoskeletal disorders, less is known about psychosocial effects of such interventions. This aim of this study was to investigate the effect of workplace physical exercise on psychosocial factors among workers with chronic musculoskeletal pain.The trial design was a 2-armed parallel-group randomized controlled trial with allocation concealment.

The dynamic properties of the actin cytoskeleton in smooth muscle cells play an important role in a number of cardiovascular disease states. The state of actin does not only mediate mechanical stability and contractile function but can also regulate gene expression via myocardin related transcription factors (MRTFs). These transcriptional co-activators regulate genes encoding contractile and cytos
