Background: Preclinical rodent models for Parkinson's disease (PD) based on viral human alpha-synuclein (h-αSyn) overexpression recapitulate some of the pathological hallmarks as it presents in humans, such as progressive cell loss and additional synucleinopathy in cortical and subcortical structures. Recent studies have combined viral vector-based overexpression of human wild-type αSyn with the s

Tau accumulation starts during the preclinical phase of Alzheimer's disease and is closely associated with cognitive decline. For preventive purposes, it is important to identify factors associated with tau accumulation and spread. Studying genetically identical twin-pairs may give insight into genetic and environmental contributions to tau pathology, as similarities in identical twin-pairs largel

Background: Patient safety gained public notoriety following the 1999 report of the Institute of Medicine: To Err is Human – Building a Safer Health System which summarized a culminated decades' worth of research that had so far been largely ignored. The aim of this study was to analyze the report's impact on patient safety research in anesthesiology.Methods: A bibliometric analysis was performed

Background. Persistent intolerable pain is still an unsolved issue with a huge socioeconomic impact. To develop appropriate treatments, it is crucial to understand the complex mechanisms underlying pain and how they change during sustained pain stimuli or during pathological conditions. In particular, it is essential to clarify how the endogenous analgesic centres which are present in the brain, s

Nurses’ work-related stress during the Covid-19 pandemicNagel C. Nilsson K. BackgroundDuring the Coronavirus pandemic, healthcare workers and primarily the nurses, were on the frontline. Many nurses have had to face exposure and facing higher risks to their own health. It is known that stress is a factor that can contribute to mental health issues and an increased turnover intention. Objective Thi

Objectives. To discover whether the proteolytic activity of prostate- specific antigen (PSA) affects the structure and function of parathyroid hormone-related protein (PTHrP), as both are abundant components of human seminal plasma. Methods. The ability of PTHrP to act as a substrate was studied by incubating a synthetic polypeptide, consisting of 34 amino acid residues of the amino-terminal domai

INTRODUCTION: Since 2005, disease-related human genetic diversity has been intensively characterized using genome-wide association studies (GWAS). Understanding how and by whom this work was performed may yield valuable insights into the generalizability of GWAS discoveries to global populations and how high-impact genetics research can be equitably sustained in the future.MATERIALS AND METHODS: W

Background: Traumatic brain injury (TBI) is a common injury and constitutes up to 3% of emergency department (ED) visits. Current studies show that TBI is most commonly inflicted in older patients after ground-level falls. These patients often take medications affecting coagulation such as anticoagulants or antiplatelet drugs. Guidelines for ED TBI-management assume that anticoagulation therapy (A

The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac

PURPOSE: Children with cerebral palsy (CP) have an increased risk of cognitive difficulties and should be offered cognitive assessments. In Sweden, the CP Cog protocol recommends children with CP undergo cognitive assessments at the start of primary and secondary school. To assess children with CP can be challenging, in particular when children are non-vocal or do not speak the local language. In

Educational and income gradients in health are well established in the literature but there is need for a better understanding of how mental health inequalities change over time, and what drives the development. We aim to study how psychiatric diagnosis and its income-related inequality have changed over time in Sweden and to make a first attempt at disentangling the development by decomposing any

Breast cancer susceptibility variants frequently show heterogeneity in associations by tumor subtype1-3. To identify novel loci, we performed a genome-wide association study including 133,384 breast cancer cases and 113,789 controls, plus 18,908 BRCA1 mutation carriers (9,414 with breast cancer) of European ancestry, using both standard and novel methodologies that account for underlying tumor het

Gambling Disorder (GD) has recently been reclassified from an impulse-control disorder to a behavioural addiction and, as in other addictive disorders, the dopaminergic reward system is involved. According to neuroimaging studies, alterations within the striatal dopaminergic signalling can occur in GD. However, the findings to date are controversial and there has been no agreement yet on how the r

Smoking is a well-known risk factor for Graves' ophthalmopathy (GO) in patients suffering from Graves' disease (GD). Cysteine-rich angiogenic inducer 61 (CYR61), which has multiple physiological functions, has been shown to be associated with GD and GO. In this study, we aimed to investigate the association between smoking and CYR61 concentrations in GD patients with and without GO. Serum CYR61 wa

1. The European Water Framework Directive requires the determination of ecological status in European fresh and saline waters. This is to be through the establishment of a typology of surface water bodies, the determination of reference (high status) conditions in each element (ecotype) of the typology and of lower grades of status (good, moderate, poor and bad) for each ecotype. It then requires

Popular Abstract in Swedish Alla levande celler har förmåga att känna av och på olika sätt anpassa sig till sin omgivning, antingen de ensamma utgör en hel organism eller är en av många miljarder celler i ett stort djur. Varje enskild cell kan bara ta emot en begränsat mängd olika sorters signaler och bara reagera på ett likaledes begränsat antal sätt. Den en- eller fåcelliga organismen är därmed The G protein-coupled receptors form one of the largest families of proteins involved in signalling between cells. It contains receptors for molecules as diverse as biogenic amines, glycoproteins and enzymes. The manuscripts included in this thesis together describe the initial characterisation of a previously unknown receptor of this class. A DNA fragment was cloned from a mouse genomic library.

The German federal state of North Rhine-Westphalia (NRW) is home to one of the most important industrial regions in Europe, and is the first German state to have adopted its own Climate Protection Law (CPL). This paper describes the long-term (up to 2050) mitigation scenarios for NRW's main energy-intensive industrial sub-sectors which served to support the implementation of the CPL. It also descr

"It’s not like I’ve lived on a park bench…" : About stigmas surrounding narcotics abuse There are stigmas surrounding the abuse of narcotics that the members of society share and uphold. The stigma is produced by the idea of who a narcotics abuser is on a political level, an idea that will be reproduced by the instances of society, such as the health care or social services, that deal w

Validation of gene × environment interaction results from epidemiological studies in randomized clinical trials (RCTs) is usually hampered by insufficient statistical power. Genotype-based recall (GBR) refers to the design of studies in which subgroups of the population are selected based on their genotypes. In this thesis we test if a GBR approach of recruiting two groups of participants with dis

En stor del av Östafrikas landsbygdsbefolkning är självförsörjande jordbrukare som på grund av begränsade markytor och förändrade klimatförhållanden riskerar misslyckade skördar och ökad fattigdom. I takt med att befolkningen växer blir miljöproblem som avskogning, erosion och urlakade jordar, samt övergödning av vattendrag och sjöar alltmer påtagliga. Syftet med den här studien är att kartläggaSub-Saharan Africa suffers from land degradation, depletion of natural resources and rural poverty. In the Lake Victoria Basin, where large parts of the population are small scale farmers, people are facing such issues coupled with altered climatic conditions. The focus area of this study is the Mara region in northern Tanzania, situated on the eastern lakeshore. Mara has experienced a doubling of
