Altered brain metabolism in frontotemporal dementia and psychiatric disorders : involvement of the anterior cingulate cortex

Background: Behavioural symptoms and frontotemporal hypometabolism overlap between behavioural variant of frontotemporal dementia (bvFTD) and primary psychiatric disorders (PPD), hampering diagnostic distinction. Voxel-wise comparisons of brain metabolism might identify specific frontotemporal-(hypo)metabolic regions between bvFTD and PPD. We investigated brain metabolism in bvFTD and PPD and its

An atlas of genetic determinants of forearm fracture

Osteoporotic fracture is among the most common and costly of diseases. While reasonably heritable, its genetic determinants have remained elusive. Forearm fractures are the most common clinically recognized osteoporotic fractures with a relatively high heritability. To establish an atlas of the genetic determinants of forearm fractures, we performed genome-wide association analyses including 100,0

A search for new resonances in multiple final states with a high transverse momentum Z boson in √s = 13 TeV pp collisions with the ATLAS detector

A generic search for resonances is performed with events containing a Z boson with transverse momentum greater than 100 GeV, decaying into e + e − or μ + μ −. The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider correspond to an integrated luminosity of 139 fb −1. Two invariant mass distributions are exami

Riskfylld socialisering i området som policyproblem: Policyn CTC som rumskapande biopolitisk maktteknologi

In this thesis I use a feminist poststructuralist framework to analyse a policy document within the program Communities That Care, implemented in Malmö, Sweden. This urban security initiative makes the socialization of children and youth its object, and problematizes the social and built organisation of local areas as a root cause of urban insecurity. It creates spaces for intervention (CTC-areas)

Does investor diversity in loan syndications affect the initial returns in the secondary market?

The syndicated loan market is a major source of corporate funding, raising $5 trillion in 2021. The secondary market where these loans are traded has seen a rapid growth in the last few decades. This growth was accompanied by the entrance of new types of participants, increasing the investor diversity. Similar to other markets, there is a price difference between the initial stage and the entrance

Caffeine Intake, Plasma Caffeine Level, and Kidney Function : A Mendelian Randomization Study

Caffeine is a psychoactive substance widely consumed worldwide, mainly via sources such as coffee and tea. The effects of caffeine on kidney function remain unclear. We leveraged the genetic variants in the CYP1A2 and AHR genes via the two-sample Mendelian randomization (MR) framework to estimate the association of genetically predicted plasma caffeine and caffeine intake on kidney traits. Genetic

Tumour origin, diagnostic accuracy and histopathological evaluation in patients with periampullary cancer : nationwide cohort study

Background: The prevalence of different periampullary cancers (pancreatic ductal adenocarcinoma, distal cholangiocarcinoma, ampullary cancer and duodenal cancer) is heterogeneous in the literature. During the 2010s, a standardized histopathological protocol for pancreatoduodenectomy specimens based on axial slicing was adopted in Sweden. The present study sought to provide information about periam

Seeing for understanding : Unlocking the potential of visual research in information systems

In this paper, we argue that information researchers should use images as a source of data. The information systems field is overwhelmingly visual in nature. Not only is the Internet crammed with images, but also almost every detail observed during fieldwork in different research settings can be captured in the form of digital images. Yet, we rarely engage with those images. Except for sporadic vi

A plant-based milk powder that functions as a substitution for regular milk powder

This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. The different ratios were 100% sucrose; 100% maltodextrin; 50% ma

[18F]PSMA-1007 PET is comparable to [99mTc]Tc-DMSA SPECT for renal cortical imaging.

BACKGROUND: Scintigraphy using technetium-99m labelled dimercaptosuccinic acid ([99mTc]Tc-DMSA), taken up in the proximal tubules, is the standard in functional imaging of the renal cortex. Recent guidelines recommend performing [99mTc]Tc-DMSA scintigraphy with single photon emission computed tomography (SPECT). Prostate-specific membrane antigen (PSMA) targeted positron emission tomography (PET)

Trace Water Changes Metal Ion Speciation in Deep Eutectic Solvents : Ce3+ Solvation and Nanoscale Water Clustering in Choline Chloride-Urea-Water Mixtures

Eutectic mixtures of choline chloride, urea, and water in deep eutectic solvent (DES)/water molar hydration ratios (w) of 2, 5, and 10, with dissolved cerium salt, were measured using neutron diffraction with isotopic substitution. Structures were modeled using empirical potential structure refinement (EPSR). Ce3+ was found to form highly charged complexes with a mean coordination number between 7

Contractions of English semi-modals : the emancipating effect of frequency

GERMAN SUMMARY: Gegenstand dieser Arbeit sind die verkürzten Formen (Kontraktionen) der englischen Modalausdrücke (‘semi-modals’) 'BE going to', 'HAVE got to' und 'want to'. Die Kontraktionen sind in der gesprochenen Sprache häufig und zeigen sich in den Schreibweisen 'gonna', 'gotta' und 'wanna'. Sie werden im Nordamerikanischen Englisch untersucht. Den Hintergrund der Arbeit bildet die GrammThe current restructuring of the English modal system has long been noted as an ongoing language change process. Semi-modal constructions such as 'BE going to' and 'HAVE got to' are textbook cases of grammaticalization. As grammaticalization comes with a rise in frequency, these semi-modals are also typical examples of the ‘reducing effect’ of frequency, which leads to the contracted forms 'gonna'

Neuroendocrine effects in printing workers exposed to toluene

The effect of exposure to toluene on plasma concentrations of testosterone, prolactin, luteinising (LH) and follicle stimulating (FSH) hormones was investigated in 47 rotogravure printers (time weighted average air toluene below 80 ppm; blood toluene concentration post-shift 0.19-7.99 mumol/l) and compared with a reference group. Increasing exposure concentrations of toluene (concentrations less t

Longitudinal changes in hippocampal texture from healthy aging to Alzheimer's disease

Early detection of Alzheimer's disease is essential to develop preventive treatment strategies. Detectible change in brain volume emerges relatively late in the pathogenic progression of disease, but microstructural changes caused by early neuropathology may cause subtle changes in the MR signal, quantifiable using texture analysis. Texture analysis quantifies spatial patterns in an image, such as

Exploring the relationship between social jetlag with gut microbial composition, diet and cardiometabolic health, in the ZOE PREDICT 1 cohort

Purpose: In this study, we explore the relationship between social jetlag (SJL), a parameter of circadian misalignment, and gut microbial composition, diet and cardiometabolic health in the ZOE PREDICT 1 cohort (NCT03479866). Methods: We assessed demographic, diet, cardiometabolic, stool metagenomics and postprandial metabolic measures (n = 1002). We used self-reported habitual sleep (n = 934) to

Cell-Free DNA as a Biomarker in a Rodent Model of Chlorpyrifos Poisoning Causing Mitochondrial Dysfunction

Introduction: Organophosphates (OPs) are a major public health problem worldwide due to ease of access and high toxicity lacking effective biomarkers and treatment. Cholinergic agents such as OPs and carbamates are responsible for many pesticide-related deaths. While the inhibition of AChE is thought to be the main mechanism of injury, there are other important pathways that contribute to the over

Emulsifier adsorption kinetics influences drop deformation and breakup in turbulent emulsification

Turbulent drop breakup is of large importance for applications such as food and pharmaceutical processing, as well as of substantial fundamental scientific interest. Emulsification typically takes place in the presence of surface-active emulsifiers (natural occurring and/or added). Under equilibrium conditions, these lower the interfacial tension, enabling deformation and breakup. However, turbule

Protonation of Homocitrate and the E1 State of Fe-Nitrogenase Studied by QM/MM Calculations

Nitrogenase is the only enzyme that can cleave the strong triple bond in N2, making nitrogen available for biological life. There are three isozymes of nitrogenase, differing in the composition of the active site, viz., Mo, V, and Fe-nitrogenase. Recently, the first crystal structure of Fe-nitrogenase was presented. We have performed the first combined quantum mechanical and molecular mechanical (
