Popular Abstract in Swedish Deponier (soptippar) har förändrats kraftigt de senaste decennierna. Detta beror främst på ändrad lagstiftning vilken i sin tur till stor del bygger på en önskan att skydda miljön. Dock har lag¬stiftningen implementerats utan riktig kännedom om dess konsekvenser för utsläppen från deponier på lång sikt. För att öka förståelsen för konsekvenserna genomfördes det forskninWaste management in Europe has changed, mainly as a result of stricter regulations, most notably the European Landfill Directive 1999/31/EC. In Sweden, landfill tax and a ban on the landfilling of waste with total organic carbon content over 10 % have diverted large amounts of waste from landfills. The biogeochemistry of landfills has changed due to their reduced organic content. The research pres

Objective: To determine the potential of plasma phosphorylated tau 217 (p-tau217) and tau positron emission tomography (PET) to assess disease modification in treatment trials. Design, Setting, and Participants: This diagnostic/prognostic study used longitudinal data from the Anti-Amyloid Treatment in
Aims Aortic valve calcification (AVC) is an underlying pathophysiological mechanism for aortic stenosis that is common in the elderly, but less is known in younger individuals. The aim was to study the prevalence and associated characteristics of AVC in a middle-aged general population. Methods and results Data were obtained from the Swedish CArdioPulmonary bioImage Study (SCAPIS) comprising 30 15
BACKGROUND: Prostate cancer is a heterogenous disease, but once it becomes metastatic it eventually becomes treatment resistant. One mechanism of resistance to AR-targeting therapy is lineage plasticity, where the tumor undergoes a transformation to an AR-indifferent phenotype, most studied in the context of neuroendocrine prostate cancer (NEPC). However, activation of additional de- or trans-diff
Background: Cyclic Cushing's syndrome (cCS) features fluctuating cortisol secretion, often causing diagnostic errors or delays, and possibly poorer outcomes. We aimed to identify unpublished cCS cases to characterise clinical challenges and guide strategies for improving outcomes by characterising cycle patterns, peak frequency, and evaluating complications. Methods: This was a retrospective obser

Popular Abstract in Swedish Vad har den slaviskt inspirerade östersjökeramiken som arkeologer finner i Skandinavien med slaver att göra? Levde de som gäster i huset? Vikingen och hanseaten har sedan länge sina platser inbokade på den historiska scenen. Under äldre medeltid rörde sig även andra aktörer över Östersjöns vatten. Främmande gäster besökte och bosatte sig i Skandinavien. Bland dem fanns Scholarly texts on Slavic-Scandinavian relations have concentrated on two main areas of interest. During the Viking Age the economic and social contacts between the lake Mälaren district and Rus’ were extensive. However, at the beginning of the Middle Ages, political antagonism between the two expanding realms of the Svear and the Novgorodians is noticeable. In southern Scandinavia, the hostility
Popular Abstract in Swedish Parkinsons sjukdom beror på att de dopamin-producerande cellerna i hjärnan dör. Detta leder till minskad rörlighet, svårigheter i att påbörja och avsluta en rörelse, balanssvårigheter och darrningar (tremor) hos de drabbade patienterna. Varför dopamincellerna dör är oklart och i nulägat kan man inte bota Parkinsons sjukdom, men man kan lindra symptomen med mediciner. PaParkinson's disease (PD) is a neurodegenerative disorder where the midbrain dopaminergic neurons are lost. Presently there is no cure for PD, and the most common treatment is to replace the lost dopamine pharmacologically by administration of the dopamine precursor L-DOPA. This works very well during the initial treatment period, but unfortunately a majority of the patients develop abnormal involu
The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. Various duct configurations have been studied, such as rectangular and trapez
Popular Abstract in Swedish Akut leversvikt medför hög risk för komplikationer orsakade av bakteriesepsis. Hög nivåer av lipopolysackarider (LPS; endotoxin) i det portala blodet kan leda till förhöjd sekretion av pro-inflammatoriska signalsubstanser från leverns Kupffer-celler, vilket har visats vara ett tidigt och viktigt tecken på leverskada. Patogenesen för inflammatorisk tarmsjukdom (?inflammaAcute liver failure is accompanied by a high rate of bacterial septic complications. High portal level of lipopolysaccharide (LPS) can lead to a pronounced secretion by Kupffer cells of pro-inflammatory mediators which have been shown to be early and important mediators of liver injury. Pathogenesis of inflammatory bowel disease (IBD) is complex; involving environmental, genetic, microbial, and im
Introduction: Vertebral fracture is a strong risk factor for future spine and hip fractures; yet recent data suggest that only 5-20% of subjects with a spine fracture are identified in primary care. We aimed to develop easily applicable algorithms predicting a high risk of future spine fracture in men and women over 50 years of age. Methods: Data was analysed from 5,561 men and women aged 50+ year
There is increasing evidence that fermentation in the large intestine is important for health, and that health-promoting effects are mediated by fermentation products such as butyric and propionic acid. As the formation of carboxylic acids (CAs) from various carbohydrates reaching the colon has been shown to vary, it is of great interest to identify food factors that could be of importance to this
Popular Abstract in Swedish I mitt doktorandprojekt har jag studerat den fästingspridda bakterien Borrelia och dess värddjur skogssork. Det övergripande syftet har varit att kartlägga den genetiska variationen i den delen av immunförsvaret som tar hand om bakterieinfektioner, som till exempel borrelia. I alla ryggradsdjur finns ett specifikt immunförsvar som kan identifiera små proteinbitar från eThe major histocompatibility complex (MHC) class IIB genes exhibit extensive allelic polymorphism, most likely maintained by pathogen-mediated balancing selection (PMBS). PMBS may operate in the form of heterozygote advantage (HA), and/or through the interaction of pathogens and specific MHC alleles via fluctuating selection (FS) or negative frequency-dependent selection (NFDS). In particular, NFD
The monosaccharide anhydrides (MAs) levoglucosan, galactosan and mannosan are products of incomplete combustion and pyrolysis of cellulose and hemicelluloses, and are found to be major constituents of biomass burning (BB) aerosol particles. Hence, ambient aerosol particle concentrations of levoglucosan are commonly used to study the influence of residential wood burning, agricultural waste burning

Background. A once commonly held belief was that surgery is too complicated, too expensive, and too ineffectively addressing a too minor proportion of the burden of disease to deserve priority in a setting of scarce healthcare resources in low- and middle-income countries. Yet, essential surgical care can be as highly cost-effective as other common public health interventions, and surgical service
Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. It is thus of high importance to understand the characteristics of each
Microalgal range expansions are increasing in frequency and magnitude worldwide mostly due to anthropogenic factors. However, they often remain unnoticed until mass development (algal blooms) occurs due to difficulties in detection when population densities are low. However, population genetic methods offer an approach to investigate these patterns. One such potentially expanding bloom-forming spe
BackgroundSevere perineal trauma (SPT) affecting the anal sphincter muscle complex is a serious complication following childbirth, associated with short-term and long-term maternal morbidity. Effective preventive strategies are still scarce. The aim of the Oneplus trial was to test the hypothesis that the presence of a second midwife during the second stage of labour, with the purpose of preventin
