Physiological aspects of the glomerular filtration barrier

Proteinuria is associated with progression of kidney disease and is an independent risk factor for cardiovascular morbidity and mortality. The pathophysiological alterations resulting in proteinuria are obscure, although proteinuria is often associated with pathological changes in the glomerular filtration barrier (GFB). It is therefore of great interest to study the physiology of the GFB, in orde

Adiabatic connections and properties of coupling-integrated exchange-correlation holes and pair densities in density functional theory

We demonstrate a method that likely will improve the accuracy of functionals used in density functional theory and pair density functional theory. In deriving the method we show that the coupling-integrated exchange-correlation hole used in density functional theory obeys all the N-representability conditions as non-integrated holes and we give two such conditions, not normally used by the density

Socialförsäkringar och globalisering

Globaisering ställer krav på socialförsäkringar som ger ett gott skydd, men även på en design som främjar rörlighet. Rapporten analyserar hur socialförsäkringar bör utformas för att ge effektivitets- och fördelningsvinster.

ATLAS Run 1 searches for direct pair production of third-generation squarks at the Large Hadron Collider.

This paper reviews and extends searches for the direct pair production of the scalar supersymmetric partners of the top and bottom quarks in proton-proton collisions collected by the ATLAS collaboration during the LHC Run 1. Most of the analyses use 20 [Formula: see text] of collisions at a centre-of-mass energy of [Formula: see text] TeV, although in some case an additional [Formula: see text] of

Within-host competition between Borrelia afzelii ospC strains in wild hosts as revealed by massively parallel amplicon sequencing.

Infections frequently consist of more than one strain of a given pathogen. Experiments have shown that co-infecting strains often compete, so that the infection intensity of each strain in mixed infections is lower than in single strain infections. Such within-host competition can have important epidemiological and evolutionary consequences. However, the extent of competition has rarely been inves

Low impact of dry conditions on the CO2 exchange of a Northern-Norwegian blanket bog

Northern peatlands hold large amounts of organic carbon (C) in their soils and are as such important in a climate change context. Blanket bogs, i.e. nutrient-poor peatlands restricted to maritime climates, may be extra vulnerable to global warming since they require a positive water balance to sustain their moss dominated vegetation and C sink functioning. This study presents a 4.5 year record of

Apparent Dead Space with the Anesthetic Conserving Device, AnaConDa®: A Clinical and Laboratory Investigation.

The anesthetic conserving device (ACD) reduces consumption of volatile anesthetic drug by a conserving medium adsorbing exhaled drug during expiration and releasing it during inspiration. Elevated arterial CO2 tension (PaCO2) has been observed in patients using the ACD, despite tidal volume increase to compensate for larger apparatus dead space. In a test lung using room temperature dry gas, this

Distinct metabolomic signatures are associated with longevity in humans.

Alterations in metabolism influence lifespan in experimental models, but data in humans are lacking. Here we use liquid chromatography/mass spectrometry to quantify 217 plasma metabolites and examine their relation to longevity in a large cohort of men and women followed for up to 20 years. We find that, higher concentrations of the citric acid cycle intermediate, isocitrate, and the bile acid, ta

Enteral leptin administration affects intestinal autophagy in suckling piglets

Leptin has been shown to play an integral role in the endocrine regulation of metabolism. Moreover, a substantial amount of this peptide has been found in colostrum and milk. The aim of the study was to investigate the effects of exogenous leptin, administered intragastrically, on the process of autophagy and the changes in cell hyperplasia and hypertrophy in the small intestine mucosa. Three grou

Six new loci associated with body mass index highlight a neuronal influence on body weight regulation

Common variants at only two loci, FTO and MC4R, have been reproducibly associated with body mass index (BMI) in humans. To identify additional loci, we conducted meta-analysis of 15 genome-wide association studies for BMI (n > 32,000) and followed up top signals in 14 additional cohorts (n > 59,000). We strongly confirm FTO and MC4R and identify six additional loci (P < 5 x 10(-8)): TMEM18, KCTD15

The Phenomenology of Specialization of Criminal Suspects

A criminal career can be either general, with the criminal committing different types of crimes, or specialized, with the criminal committing a specific type of crime. A central problem in the study of crime specialization is to determine, from the perspective of the criminal, which crimes should be considered similar and which crimes should be considered distinct. We study a large set of Swedish

Muscle strength and physical education: epidemiological studies of factors in adolescence and their association with later morbidity

Popular Abstract in Swedish Avhandlingen består av fyra delstudier och är tematiskt uppdelad i två delar. I den första delen undersöker jag vilken betydelse betyget i Gymnastik (nuvarande Idrott & Hälsa) har för framtida sjukdom med fokus på rörelseorganen. I den andra delen undersöker jag vilken betydelse isometrisk muskelstyrka (d.v.s. kraft alstrad utan nämnvärd förkortning av muskeln) har Although Physical Education (PE) is a part of the school curriculum in many countries, the association between the performance in PE and later morbidity is largely unknown. An important marker of health, cardiorespiratory fitness is inversely associated with future cardiovascular disease (CVD) and mortality. It has been suggested that muscle strength is associated in a similar way. However, whethe

On Steady Water Waves and Their Properties

Abstract: This thesis consists of four papers related to various aspects of steady water waves. Paper I: Deep-water waves with vorticity: symmetry and rotational behaviour. We show that for steady, periodic, and rotational gravity deep-water waves, a monotone surface profile between troughs and crests implies symmetry. It is observed that if the vorticity function has a bounded derivative, the

Psychometric properties of the Chinese version of the Functional Assessment of Cancer Therapy-Cervix (FACT-Cx) measuring health-related quality of life

Background: The Functional Assessment of Cancer Therapy (FACT) is one of the most commonly used self-report instruments for evaluation of health-related quality of life in oncology patients. However, cultural considerations necessitate testing of the subscales in different populations. We sought to qualitatively and quantitatively investigate the applicability and psychometric properties of the Ch

Anti-Tumor Effects of CysLT2R in Epithelial Cancer

The pro-inflammatory cysteinyl leukotrienes (cysLTs) are implicated in several pathological disorders, such as asthma and inflammatory diseases. The well-established connection between chronic inflammation and cancer implicates inflammatory mediators in cancer progression. It is therefore of interest to examine the effects of the CysLTs in cancer. The biological effects of CysLTs are mediated thro

Structure and Function of HAMLET: Epitopes, Membrane Interactions and Molecular Recognition

HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a complex of partially unfolded human alpha-lactalbumin and oleic acid that kills many different types of tumor cells and shows therapeutic efficacy in animal models and clinical studies. This thesis aims to (1) elucidate the structure of HAMLET and the exposure of biologically active domains, (2) define the contribution of lipids to t

Temperament and Character in the Child and Adolescent Twin Study in Sweden (CATSS): Comparison to the General Population, and Genetic Structure Analysis

Background: The Child and Adolescent Twin Study in Sweden (CATSS) is an on-going, large population-based longitudinal twin study. We aimed (1) to investigate the reliability of two different versions (125-items and 238-items) of Cloninger's Temperament and Character Inventory (TCI) used in the CATSS and the validity of extracting the short version from the long version, (2) to compare these person
