Lateralized deficits after unilateral AAV-vector based overexpression of alpha-synuclein in the midbrain of rats on drug-free behavioral tests

Background: Preclinical rodent models of Parkinson's aim to recapitulate some of the hallmarks of the disease as it presents in humans, including the progressive neuronal loss of dopaminergic neurons in the midbrain as well as the development of a behavioral phenotype. AAV vector-based models of alpha-synuclein overexpression are a promising tool to achieve such animal models with high face and pr

How much do we really care what we pick? : Pre-verbal and verbal investment in choices concerning faces and figures

Every day we make choices, but our degree of investment in them differs, both in terms of pre-verbal experience and verbal justification. In an earlier experimental study, participants were asked to pick the more attractive one among two human faces, and among two abstract figures, and later to provide verbal motivations for these choices. They did not know that in some of the cases their choices

Deglaciation history and subsequent lake dynamics in the Siljan region, south-central Sweden, based on new LiDAR evidence and sediment records

The Siljan region hosts Europe´s largest impact structure. The high-relief landscape, with a central granite dome bordered by lake basins, contains an array of glacial and shore-level landforms. We investigated its deglaciation history by mapping and analysing landforms on high resolution LiDAR-based Digital Surface Models coupled with well-dated sediment successions from peat and lake sediment coThe Siljan region hosts Europe´s largest impact structure.

Business Models for Sustainable Consumption : Identifying and Overcoming Barriers to Rental and Reuse of Home Furnishings

It is widely recognised that society is consuming at levels and in ways that are unsustainable. Sustainable business models, broadly defined as those that consider economic, ecological and social value, hold promise for shifting consumption patterns. By facilitating activities such as rental and reuse, including second-hand, repair, refurbishment, and upcycling, they can help to provide more susta

Att lära av varandra för att styra och leda bättre tillsammans : Case för politikens genomslag

How do elected officials and managers in municipalities and regions manage and lead together in the best way? In order to deal with society's challenges and get impact and results from political decisions, well-functioning cooperation is a necessity.In the book, leading elected representatives and managers share their experiences and success factors. The book contains both theory and practice, in

Atomic structural mechanism for ferroelectric-antiferroelectric transformation in perovskite NaNbO3

Sodium niobate (NaNbO3 or NN) is described as "the most complex perovskite system,"which exhibits transitions between, as well as coexistence of, several ferroelectrics (FE) and antiferroelectric (AFE) phases at different temperatures. Recently, solid solutions of NN with stabilized AFE phases(s) have gained attention for energy-related applications, such as high-density energy storage and electro

Month of birth and the risk of developing type 1 diabetes among children in the Swedish national Better Diabetes Diagnosis Study

Aim: Previous studies have reported an association between month of birth and incidence of type 1 diabetes. Using population-based data, including almost all newly diagnosed children with type 1 diabetes in Sweden, we tested whether month of birth influences the risk of type 1 diabetes. Methods: For 8761 children diagnosed with type 1 diabetes between May 2005 and December 2016 in the Better Diabe

Novel Perlin-based phantoms using 3D models of compressed breast shapes and fractal noise

Virtual clinical trials (VCTs) have been used widely to evaluate digital breast tomosynthesis (DBT) systems. VCTs require realistic simulations of the breast anatomy (phantoms) to characterize lesions and to estimate risk of masking cancers. This study introduces the use of Perlin-based phantoms to optimize the acquisition geometry of a novel DBT prototype. These phantoms were developed using a GP

Severe COVID-19 in people 55 and older during the first year of the pandemic in Sweden

Background: Exposure to many contacts is the main risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, while risk of serious disease and death is chiefly determined by old age and comorbidities. Relative and population-attributable fractions (PAFs) of multiple medical and social exposures for COVID-19 outcomes have not been evaluated among older adults. Objective

Platelet function testing : Current practice among clinical centres in Northern Europe

Introduction: Platelet function tests are used to screen and diagnose patients with possible inherited platelet function defects (IPFD). Some acquired platelet dysfunction may be caused by certain drugs or comorbidities, which need to be excluded before testing. Aims: To identify current practice among centres performing platelet function tests in Northern Europe. Methods: A total of 14 clinical c

Protocol for an individual patient data meta-analysis on blood pressure targets after cardiac arrest

Background: Hypotension is common after cardiac arrest (CA), and current guidelines recommend using vasopressors to target mean arterial blood pressure (MAP) higher than 65 mmHg. Pilot trials have compared higher and lower MAP targets. We will review the evidence on whether higher MAP improves outcome after cardiac arrest. Methods: This systematic review and meta-analysis will be conducted based o

For God's Sake : The Work and Long-Term Impact of Christian Missionaries in Cameroon 1844-2018

Most countries in Sub-Saharan Africa have made great strides towards more accessible and higher quality schooling and medical systems in recent years. Despite this, education and health care in Africa lag behind other developing regions and large inequalities in educational levels and health care access remain across countries, subnational regions, and gender. Cameroon, in west-central Africa, wit

Extended anticoagulation for venous thromboembolism : A survey of the American Venous Forum and the European Venous Forum

Objective: Extended anticoagulation therapy should always be considered after standard treatment of an unprovoked episode of venous thromboembolism (VTE). It can also be considered for selected patients with provoked VTE. However, the evidence-based protocols suggested by some clinical guidelines and risk assessment tools to guide this practice are limited and ambiguous. The goal of the present su

Geographical differences in tonsillar carriage rates of Fusobacterium necrophorum – A cross-sectional study in Sweden and Zambia

Background: Previously, we investigated tonsillar carriage of Fusobacterium necrophorum by PCR and found a high tonsillar carriage rate (21%) in asymptomatic 15-25year olds, but the same age group is most commonly affected by severe F. necrophorum infections. Interestingly, we found Cycle threshold (Ct)-values in asymptomaticcarriers to be high (median 29). Possibly, the Ct-value could differentia

Teori i historisk praktik

Att använda teori är en viktig del av historievetenskaperna. Med hjälp av teori kan en analys fördjupas och de empiriska resultaten göras greppbara i ett vidare sammanhang. För den som ska skriva en uppsats kan dock arbetet med teori framstå som abstrakt. Hur kan teorier bidra till historiska undersökningar? Hur arbetar man med teori – i praktiken? Det är temat i denna bok.Bokens kapitel tar avsta

Short Blood Culture Time-to-Positivity in Fusobacterium necrophorum Bacteremia is Associated with Lemierre’s Syndrome

Background: Short blood culture time-to-positivity (TTP) has been shown to correlate with infective endocarditis, yet TTP has never been investigated in Fusobacterium necrophorum bacteremia. Since Lemierre’s syndrome occurs after an oropharyngeal infection with the development and subsequent embolization of septic thrombophlebitis of the internal jugular vein, it could also be considered an endova
