BACKGROUND: Many poly- and perfluoroalkyl substances (PFAS) are persistent and have long half-lives in the human body. However, there are limited data on the different routes of elimination. Most pharmacokinetic models assume that the urinary route dominates.OBJECTIVES: Our aim was to investigate the relative importance of fecal and urinary elimination for linear perfluorooctane sulfonic acid (L-P

The study examines the narratives of the Decembrist revolt created in and around Russian state-funded cinema. By exploring the narratives surrounding a particular instance of political dissent in the past, the research seeks to uncover the factors that impact on the negotiation of cultural memory between the text and the audience in the context of state-influenced media. This exploration is based

Many women are occupationally active during pregnancy. The aim of this study was to investigate associations between exposure to chemicals during pregnancy and the risk of gestational diabetes or preeclampsia. The cohort included singleton births in Sweden between 1994 and 2014. The cohort was limited to low-educated mothers to reduce potential confounding from unidentified life-style associated f

Mitochondrial dysfunction is associated with pathogenic mitochondrial (mt)DNA mutations. The majority of mtDNA point mutations have a heteroplasmic status, which is defined as the coexistence of wild-type and mutated DNA within a cell or tissue. Previous findings demonstrated that certain mtDNA heteroplasmic mutations contribute to widely spread chronic diseases, including cancer, and alterations

Introduction: Tumor deposits are an important negative prognostic factor for long-term oncological outcomes in colorectal cancer patients, independent of lymph node status. Several novel models have been proposed to further integrate tumor deposits into the TNM-staging system, but their comparative performance remains unclear. The aim of this study was to identify, compare and validate novel progn

Context. Aims. The goal of this paper is to demonstrate the outstanding quality of the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way. We focus here on determining the proper motions of 75 Galactic globular clusters, nine dwarf spheroidal galaxies, one ultra-faint system, and the Large and Small Mage

Reducing microorganisms by UV light is has been commonly used for drinking water for many years. In other liquid products like apple juice it is a rather novel application. The advantages would be that quality parameters like aromas and vitamins are less affected by the UV treatment compared to a heat treatment. Furthermore it would probably be cheaper, as the lamps need less electrical energy tha

Nowadays, many evacuation models exist in the market, and new models are continuously released with new features. How to assess the usability and reliability of model results becomes an issue for both developers and users. Therefore, verification and validation (V&V) protocols were introduced in the assessment process of evacuation models. To conduct V&V of a model, a widely accepted test

Connecting science to political agenda-setting is essential for a sustainable transition and acceptable politics. This task is complicated by phenomena like post-truth, for which facts are a non-issue. However, post-truth is not the only issue. The practice of political spin, in which the significance of facts is reconstructed according to specific interests poses another threat to scientific cred

Fokus på plast i mark och jord: mikroplasters effekt på organismer i jord undersökt med ny teknologi inom jordekologi frågor. De enorma plastutsläppen till naturen är idag ett välkänt problem. Det är också välkänt att plast bryts ner till mindre partiklar med andra effekter, så kallade mikro- och nanoplaster. Allmänheten har visat stort intresse kring plastproblematiken i haven och mycket forskniThis study aims to investigate if micro- and nanoparticles of polystyrene affect microorganisms in soil. This was tested by using microfluidic chips, which are new for investigation of soil ecology questions, providing artificial channels reflecting soil conditions as well as being transparent for seeing real-time interactions. Eight microfluidic chips were made; four were filled with a micro- and

In the construction of high-speed railways, an important starting point is to make as little Intrusion on land as possible, therefore it is of high importance to carefully investigate which construction alternatives are the most advantageous. The purpose of this work is to compare and evaluate land use and building on viaduct. The work will be based on literature and interview studies. Sections of

Previous studies clarified that the electron enriched NADH and NADPH by RBC glycolysis could be used in an extracellular chemical reaction, where electron energies are extracted by an electron mediator methylene blue (MB). The reduced form of MB permeates the phospholipid bilayer of liposomes and reduce encapsulated ferric methemoglobin (metHb) to ferrous hemoglobin. Moreover, in vitro screening s

Populärvetenskaplig sammanfattning: Utvärdering av borrhålsloggar. Syftet med detta examensarbete var att göra en utvärdering av wireline borrhålsloggar från borrhålet Kyrkheddinge-4, 3 km öster om Staffanstorp i Skåne. Den undersökta delen av borrhålet Kyrkheddinge-4 befinner sig inom den potentiella reservoarsandstenen, Lundasandstenen. Wireline borrhålsloggar är geofysiska verktyg som används This study is an evaluation of formation characteristics, as derived from wire-line well logs, of the Lund Member in the borehole Kyrkheddinge-4, 3 km east of Staffanstorp, Skåne, Sweden, through the comparison to measured core data. The purpose is to assess the feasibility of using some of the porosity and permeability equations and cross-plots derived for the investigated section and applying th

The genetic causes of familial breast cancer are still unclear, where only less than 20% have evident germline mutations. Most studies focus on mutations that cause a direct impact in the protein, disregarding the synonymous variants, where the codon is changed but the amino acid encoded remains the same. Synonymous variants can affect mRNA stability and translation, by differences in codon usage

As the greenhouse gas emissions keep on increasing the need for solutions to help reduce emissions across all sectors has never been greater. The European Union has pointed out green hydrogen as a step in increasing the sustainability of the energy sector in Europe. Goals has been set to boost the development of hydrogen technology since the green hydrogen production today is only existing in an i

The first aim of this study was to on historical background survey women's alcohol habits and especially to investigate women aged 50-59 living in the Lund area. The second aim was to increase the understanding of how women's sex role has a restrictive influence on their alcohol habits. To investigate women's alcohol habits I made two quantitative studies. From secondary data I found t
