Plasma free fatty acids and risk of stroke in the Cardiovascular Health Study

Background: Although free fatty acids have been positively associated with risk factors for stroke, the role of plasma free fatty acids in the development of stroke has not been elucidated in older adults. Aims: We sought to examine the association between plasma free fatty acids and incident stroke. Methods: Prospective cohort of 4369 men and women ≥65 years of age in the Cardiovascular Health St

Towards a unified protocol for handling of CSF before β-amyloid measurements

Background: Widespread implementation of Alzheimer's disease biomarkers in routine clinical practice requires the establishment of standard operating procedures for pre-analytical handling of cerebrospinal fluid (CSF). Methods: Here, CSF collection and storage protocols were optimized for measurements of β-amyloid (Aβ). We investigated the effects of (1) storage temperature, (2) storage time, (3)

A Timely Journey Through the Cloud

This thesis treats the intersection between two of the largest transformations we are seeing within our society today; the cloud and the Internet-of-Things (IoT). The aim of this thesis is to investigate different ways to model and control a network of cloud services so that timing-critical IoT applications can make use of them. Examples of such applications can be autonomous and mobile robots, sm

The inner two degrees of the Milky Way : Evidence of a chemical difference between the Galactic Center and the surrounding inner bulge stellar populations

Context. Although there have been numerous studies of chemical abundances in the Galactic bulge, the central two degrees have been relatively unexplored due to the heavy and variable interstellar extinction, extreme stellar crowding, and the presence of complex foreground disk stellar populations. Aims. In this paper we discuss the metallicity distribution function, vertical and radial gradients,

Rethinking Collection Practice with Frances Lloyd-Baynes at Mia

Discussions and debates about traditional values of equity and inclusion have increased in recent years, and participants in these discussions include professional heritage institutions, journalists of the daily press and the public through social media. Museums, as keepers of cultural stories and heritage under their auspices, are increasingly examining their role in shaping a narrative of divers

Kvalitetshöjning av planglas Icke-förstörande provning av glasets hållfasthet

Hållfastheten och därmed kvaliteten på planglas varierar kraftigt beroende på förekomsten sprickor i glasets yta. Sprickorna fungerar som brottanvisningar vilket medför att man måste räkna med stora säkerhetsfaktorer då glas belastas i olika byggnadskonstruktioner. Trä som konstruktionsmaterial har en liknande problematik där man utvecklat virkessortering för att kvalitetsklassning. I den här förs

On Boredom in Winter Sleep

In this work, we focus on the film Winter Sleep (2014) by Nuri Bilge Ceylan,whose works place special emphasis on various aspects of boredom. As one of the main figures in slow cinema, Ceylan, in this influential work of art, enable us to explore boredom through three main characters: Aydın (Haluk Bilginer), Nihal (Melisa Sözen) and Necla (Demet Akbağ). By taking a closer look at the film, we anal

The will to activate library users and the making of citizens : How different rationalities influence the notion of participation in a library context

In this paper, we explore how the notion of participation informs policy documents in a public library context. Today, library users to a large extent are expected to manage on their own and society calls for self-governing, active subjects who are willing to participate. To explore the notion of participation we utilize the concept of problematization and conduct a text analysis of policy documenThis article explores how the notion of participation informs policy documents in a public library context.

Road traffic noise, air pollution, and risk of dementia - results from the Betula project

BACKGROUND: There is growing evidence for a negative impact of traffic-related air pollution on risk of dementia. However, the contribution of noise exposure to this association has been rarely examined.OBJECTIVE: We aimed to investigate the individual and combined effect of noise and air pollution on risk of dementia.METHODS: Data on dementia incidence over a 15 year period was obtained from the

Sedimentation of Nodularia spumigena and distribution of nodularin in the food web during transport of a cyanobacterial bloom from the Baltic Sea to the Kattegat

Nodularia spumigena is a toxic cyanobacteria that blooms in the Baltic Sea every year. In the brackish water of the Baltic Sea, its toxin, nodularin, mainly affects the biota in the surface water due to the natural buoyancy of this species. However, the fate of the toxin is unknown, once the cyanobacteria bloom enters the more saline waters of the Kattegat. In order to investigate this knowledge g

In-vivo validation of interpolation-based phase offset correction in cardiovascular magnetic resonance flow quantification : A multi-vendor, multi-center study

Background: A velocity offset error in phase contrast cardiovascular magnetic resonance (CMR) imaging is a known problem in clinical assessment of flow volumes in vessels around the heart. Earlier studies have shown that this offset error is clinically relevant over different systems, and cannot be removed by protocol optimization. Correction methods using phantom measurements are time consuming,

Calcium Sulphate/Hydroxyapatite Carrier for Bone Formation in the Femoral Neck of Osteoporotic Rats

This study investigated bone regeneration in the femoral neck canal of osteoporotic rats using a novel animal model. A calcium sulphate (CS)/hydroxyapatite (HA) carrier was used to deliver a bisphosphonate, zoledronic acid (ZA), locally, with or without added recombinant human bone morphogenic protein-2 (rhBMP-2). Twenty-eight-week-old ovariectomized Sprague-Dawley rats were used. A 1 mm diameter

CSF placental growth factor – a novel candidate biomarker of frontotemporal dementia

Objective: Diagnosis of frontotemporal dementia (FTD) is complicated by the overlap of clinical symptoms with other dementia disorders. Development of robust fluid biomarkers is critical to improve the diagnostic work-up of FTD. Methods: CSF concentrations of placental growth factor (PlGF) were measured in the discovery cohort including patients with FTD (n = 27), Alzheimer disease (AD) dementia (

A Helical tomotherapy as a robust low-dose treatment alternative for total skin irradiation

Mycosis fungoides is a disease with manifestation of the skin that has traditionally been treated with electron therapy. In this paper, we present a method of treating the entire skin with megavoltage photons using helical tomotherapy (HT), verified through a phantom study and clinical dosimetric data from our first two treated patients. A whole body phantom was fitted with a wetsuit as bolus, and

Digital Humanities in Sweden and Its Infrastructure : Status Quo and the Sine Qua Non

The article offers a state-of-the-art overview of a number of Digital Humanities (DH) initiatives that have emerged in Sweden over the past decade. We identify two major developments that seem to be taking place within DH, with a specific focus on the infrastructural aspects of the development: (1) a strive to open up and broaden the research output and (2) multi-disciplinary collaboration and its
