Is Long-Term Exposure to Air Pollution Associated with Episodic Memory? A Longitudinal Study from Northern Sweden

Associations between long-Term exposure to ambient air pollution and cognitive function have been observed in a few longitudinal studies. Our aim was to investigate the association between long-Term exposure to air pollution and episodic memory, a marker of early cognitive decline. We used data from the Betula study in Northern Sweden, and included participants 60 to 85 of age at inclusion, 1,469

Recruiting participants to a randomized controlled trial testing an intervention in palliative cancer care – The perspectives of health care professionals

Purpose The recruitment of participants to randomized controlled trials (RCTs) in palliative cancer care by health care professionals is often unsuccessful, which could result in failure to achieve study power. The purpose of this paper is to describe how health care professionals experienced recruiting patients and family caregivers to an RCT in palliative cancer care. Methods The study had a qua

Effect of an upstream unconnected bulge on film cooling

Film cooling technology is commonly used in a cooling system of gas turbines. For different upstream bulge configurations, the unconnected and connected configurations were used to investigate the film cooling effectiveness and downstream dimensionless temperature distributions in this paper. Moreover, the effect of the blowing ratio was analyzed by using the computational fluid mechanics. The res

Bioinformatic approaches to gene expression in leukemia. Networks and deconvolution

The aim of this thesis is develop methods to extract information from high-dimensionality data and to apply them in looking at gene-gene and gene-protein interactions in Acute Myeloid Leukemia (AML). The in silico methods developed can be used with data from other systems. The thesis gives an overview of the field for network inference and deconvolution methods, as well as a brief background on th

Hybrid magnetic iron oxide nanoparticles with tunable field-directed self-assembly

We describe the synthesis of hybrid magnetic ellipsoidal nanoparticles that consist of a mixture of two different iron oxide phases, hematite (α-Fe2O3) and maghemite (γ-Fe2O3), and characterize their magnetic field-driven self-assembly. We demonstrate that the relative amount of the two phases can be adjusted in a continuous way by varying the reaction time during the synthesis, leading to strongl

Management of community-acquired pneumonia in immunocompetent adults : updated Swedish guidelines 2017

Based on expert group work, Swedish recommendations for the management of community-acquired pneumonia in adults are here updated. The management of sepsis-induced hypotension is addressed in detail, including monitoring and parenteral therapy. The importance of respiratory support in cases of acute respiratory failure is emphasized. Treatment with high-flow oxygen and non-invasive ventilation is

MiR-335 overexpression impairs insulin secretion through defective priming of insulin vesicles

MicroRNAs contribute to the maintenance of optimal cellular functions by fine-tuning protein expression levels. In the pancreatic β-cells, imbalances in the exocytotic machinery components lead to impaired insulin secretion and type 2 diabetes (T2D). We hypothesize that dysregulated miRNA expression exacerbates β-cell dysfunction, and have earlier shown that islets from the diabetic GK-rat model h

Jamming and overpacking fuzzy microgels: Deformation, interpenetration, and compression

Tuning the solubility of fuzzy polymer microgels by external triggers, such as temperature or pH, provides a unique mechanism for controlling the porosity and size of colloidal particles on the nanoscale. As a consequence, these smart microgel particles are being considered for applications ranging from viscosity modifiers and sensing to drug delivery and as models for the glass and the jamming tr

All-seeing giants and blindfolded dwarfs: On information-asymmetries on data-driven markets

The objective of this chapter is to contribute to the understanding of the growth of this global data-driven market ecology, mainly in order to pinpoint important regulatory challenges, where individual choice and agency, as well as competition, seem undermined. Truly, this development holds many promises for new innovation, some more disruptive than others, but also poses challenges that in this

Effective proton-neutron interaction near the drip line from unbound states in F 25,26

Background: Odd-odd nuclei, around doubly closed shells, have been extensively used to study proton-neutron interactions. However, the evolution of these interactions as a function of the binding energy, ultimately when nuclei become unbound, is poorly known. The F26 nucleus, composed of a deeply bound π0d5/2 proton and an unbound ν0d3/2 neutron on top of an O24 core, is particularly adapted for t

MicroRNAs in Retinal Pathophysiology and Therapeutics

Following identification of tRNA and rRNA, the non-protein coding RNAs (ncRNAs) have been demonstrated to possess catalytic ribozyme functions (Cech et al., 1981; Guerrier-Takada et al., 1983). In recognition of the latter work, T.R. Cech and S. Altman were awarded the 1989 Noble Prize in Chemistry. Fire, et al. (1998) discovered that small double stranded RNA (ds RNA) silences the gene expression

Investigating parameters affecting the indoor temperature drop after a power cut : In-situ measurements and simulations

When looking at energy supply on a larger scale than to a single building, such as to a neighbourhood or a city, the combined effects of peak power demands can be seen to cause problems on the production side. These can be both economic and environmental and lead to the emission of greenhouse gases when fossil fuels are used to meet these peaks. Encouraging the demand side to reduce their power de

Use of participatory scenario modeling as platforms in stakeholder dialogues

Water related problems are characterized by complexities, uncertainties, and conflicting interests and there is no single “optimal” way to approach these “wicked” problems. Model-assisted participatory processes have been suggested as one way to meet these challenges. However, the use of models as ascenario tools for local planning of mitigation and adaptation strategies addressing environmental c

Imaging Atomic Scale Dynamics on III-V Nanowire Surfaces during Electrical Operation

As semiconductor electronics keep shrinking, functionality depends on individual atomic scale surface and interface features that may change as voltages are applied. In this work we demonstrate a novel device platform that allows scanning tunneling microscopy (STM) imaging with atomic scale resolution across a device simultaneously with full electrical operation. The platform presents a significan

Non-coding RNAs in beta cell insulin secretion - emerging players in Type 2 Diabetes pathogenesis

Type 2 diabetes (T2D) is a complex polygenic disease influenced by both environmental and genetic factors resulting in impaired insulin release from pancreatic beta cells and insulin resistance in target tissues. The incidence of T2D is escalating and it is projected that over 640 million people will be affected by 2040. Therefore, it is imperative to understand molecular processes that cause T2D
