Diode-laser absorption spectroscopy - applications in medicine and environmental monitoring

A major part of this thesis work has been research in a medical project, where, together with industry and clinical partners, the aim was to develop a prototype system for non-invasive monitoring of premature babies based on the optical measurement technique gas in scattering media absorption spectroscopy (GASMAS). Part of the project was to develop a 3D-printed tissue phantom based on chest X-ray

Public libraries as promoters of social sustainability?

Introduction. The aim of this paper is to critically examine how public libraries are portrayed as contributing to social sustainability. Meanings ascribed to the concept are investigated and if, and then how, the public library is shaped in relation to it.Method. Library plans from five municipalities in Sweden are analysed and discussed in the light of previous research. Analysis. Bacchi’s metho

PAK4 suppresses RELB to prevent senescence-like growth arrest in breast cancer

Overcoming cellular growth restriction, including the evasion of cellular senescence, is a hallmark of cancer. We report that PAK4 is overexpressed in all human breast cancer subtypes and associated with poor patient outcome. In mice, MMTV-PAK4 overexpression promotes spontaneous mammary cancer, while PAK4 gene depletion delays MMTV-PyMT driven tumors. Importantly, PAK4 prevents senescence-like gr

Reconsidering the Role of Farmer Politics in Swedish Democratization

In discussions of Scandinavian democratization, it is commonplace to argue that long- standing farmer representation in parliament and a lack of feudalism encouraged a democratic-participatory civic culture within the peasant farmer class – or perhaps in the population as a whole. The present essay questions this interpretation in the Swedish case. It centers on a re-interpretation of farmer polit

The diversity and evolution of odorant receptors in beetles (Coleoptera)

The insect odorant receptors (ORs) are amongst thelargest gene families in insect genomes and the primarymeans by which insects recognize volatile compounds.The evolution of ORs is thus instrumental inexplaining the chemical ecology of insects and as amodel of evolutionary biology. However, althoughORs have been described from numerous insect species,their analysis within and amongst the insectord

Trait self-control, exercise and exercise ambition : Evidence from a healthy, adult population

This study explores if self-control predicts exercise ambition and actual exercise, and if exercise ambition predicts actual exercise. Members and guests at a not-for-profit sports club were invited to participate. 264 individuals completed a self-reported (Self-Control Scale) measure of self-control, and responded to questions about actual exercise as well as exercise ambition prior to their work

Synthesis of N-Containing Compounds: Development of Methodology and its Application in Total Synthesis

This thesis aims to develop new synthetic methods and explore the possibilities to apply it in the total synthesis of natural products.Chapter 2 deals with a mild procedure for the synthesis of a-keto amides by a-oxidation of the corresponding aketo amines mediated by pyrrolidine and TEMPO. The method can also be applied to the synthesis of a-keto thioamides and a-keto amidines.Chapter 3 deals witThis thesis aims to develop new synthetic methods and explore the possibilities to apply it in the total synthesis of natural products.Chapter 2 deals with a mild procedure for the synthesis of a-keto amides by a-oxidation of the corresponding aketo amines mediated by pyrrolidine and TEMPO.

Matrisome Properties of Scaffolds Direct Fibroblasts in Idiopathic Pulmonary Fibrosis

In idiopathic pulmonary fibrosis (IPF) structural properties of the extracellular matrix (ECM) are altered and influence cellular responses through cell-matrix interactions. Scaffolds (decellularized tissue) derived from subpleural healthy and IPF lungs were examined regarding biomechanical properties and ECM composition of proteins (the matrisome). Scaffolds were repopulated with healthy fibrobla

Platelet Indices and Risk of Death and Cardiovascular Events : Results from a Large Population-Based Cohort Study

Studies evaluating the relationship between platelet indices and cardiovascular (CV) outcomes yielded conflicting results. We assessed the incidence of adverse events according to baseline quintiles of platelet indices in the prospective cohort of the Malmö Diet and Cancer Study. A total of 30,314 individuals (age 57 ± 8 years) were followed for a median of 16 years (468,490 person-years). Outcome

Heart rate and premature atrial contractions at 24hECG independently predict atrial fibrillation in a population-based study

BACKGROUND: Low resting heart rate and premature atrial contractions (PACs) predict incident atrial fibrillation (AF) and could be interdependent, since PACs occur in the gaps between normal beats.OBJECTIVE: To study the association between low heart rate at 24hECG, PACs and incident AF in a prospective population-based cohort.METHODS: In the Malmö Diet and Cancer study, 24hECGs were performed in

CHA2DS2VASc score and adverse outcomes in middle-aged individuals without atrial fibrillation

AIMS: The CHA2DS2VASc score is used to evaluate the risk of thromboembolic events in patients with non-valvular atrial fibrillation. We assessed the prognostic yield of CHA2DS2VASc for new-onset atrial fibrillation, cardiovascular morbidity and mortality in a non-atrial fibrillation population.METHODS: We analysed a population-based cohort of 22,179 middle-aged individuals with (n = 3542) and with

Baddeleyite formation in zircon by Ca-bearing fluids in silica-saturated systems in nature and experiment : resetting of the U–Pb geochronometer

Intergrowths of baddeleyite have been found in zircon grain interiors from amphibolite- and granulite-facies felsic rocks from southwest Greenland. The zircon grains are either close to or in direct contact with quartz. A series of experiments has been conducted using natural, unaltered zircon grains ± SiO2 in H2O–CaCl2, and H2O–Ca(OH)2 solutions with varying molar proportions of Ca to Si at 900 °

Assessing heterogeneous effects and their determinants via estimation of potential outcomes

When analyzing effect heterogeneity, the researcher commonly opts for stratification or a regression model with interactions. While these methods provide valuable insights, their usefulness can be somewhat limited, since they typically fail to take into account heterogeneity with respect to many dimensions simultaneously, or give rise to models with complex appearances. Based on the potential outc

Cloning and functional expression of the guinea pig neuropeptide Y Y2 receptor

Five neuropeptide Y (NPY) receptor subtypes have been cloned in mammals. The degree of sequence conservation differs considerably between subtypes as well as between evolutionary lineages. To shed further light on this, we have cloned the five NPY receptors in the guinea pig. Here, we report the cloning of the guinea pig Y2 receptor. The Y2 receptor is generally highly conserved, with 90-95% ident

Characterization of the receptor response for the neuropeptide Y-evoked suppression of parasympathetically-mediated contractions in the guinea pig trachea

Neuropeptide Y (NPY) acts via several distinct receptor types. The aim of the present study was to examine which NPY receptors are coupled to inhibition of parasympathetically-mediated contractions of the isolated guinea pig trachea. Electrical field stimulation of tracheal rings evoked a rapid twitch, which was abolished by atropine (1 microM). NPY, the structurally related hormone peptide YY (PY
