Phosphatidylcholine hydroperoxide-induced THP-1 cell adhesion to intracellular adhesion molecule-1

The accumulation of phosphatidylcholine hydroperoxide (PCOOH), a primary oxidation product of phosphatidylcholine (PC), in blood plasma and tissues has been observed in various pathological conditions, including atherosclerosis. However, the biological roles of PCOOH in these conditions remain unknown. To estimate the atherogenicity of PCOOH, we evaluated the effect of PCOOH on THP-1 monocytic cel

Twisted nanoribbons from a RGD-bearing cholic acid derivative

In light of the biomedical interest for self-assembling amphiphiles bearing the tripeptide Arg-Gly-Gly (RGD), a cholic acid derivative was synthesized by introducing an aromatic moiety on the steroidal skeleton and the RGD sequence on the carboxylic function of its chain 17–24, thus forming a peptide amphiphile with the unconventional rigid amphiphilic structure of bile salts. In aqueous solution,

Does Voluntary Governance Work? : Insights from Specialty Coffee

Jordbruket har en stor miljöbelastning, men är också alltmer centralt för att finna lösningar på hållbarhetsproblem. Ett angreppssätt för ökad hållbarhet är politisk styrning och reglering. I avhandlingen analyserar jag några frivilliga marknadsbaserade regleringar: certifiering och rapportering. Detta är regleringar som involverar företag och konsumenter. Jag har undersökt hur några sådana initiaAgricultural businesses contribute to sustainability problems, but they are also increasingly central to the effort to develop solutions. One way of moving toward sustainability is through regulatory governance. In this thesis, I analyze a tool of regulatory governance called voluntary market-based regulatory initiatives. Specifically, I investigate two types of initiatives, certification and disc

Virtual Bodies in Ritual Procession — Digital co-production for actors and interpreters of the past

This article will present and discuss the process of digital co-production and audiences' responses to the full-scale interactive, gestural, visual and musical experience of a Virtual Reality arts play. This was inspired by cist-slab images from the Kivik Grave, which is Sweden's most famous Bronze Age grave. The aim of the VR arts play was to use digital technology to engage users as time-travell

Classification of bird song syllables using wigner-ville ambiguity function cross-terms

A novel feature extraction method for lowdimensional signal representation is presented. The features are useful for classification of non-stationary multi-component signals with stochastic variation in amplitudes and time-frequency locations. Using a penalty function to suppress the Wigner-Ville ambiguity function auto-terms, the proposed feature set is based on the cross-term doppler- and lag pr

Integration of reliability analysis into mini-plate fixation strategy used in human mandible fractures : Convalescence and healing periods

Purpose: The objective was to assess the reliability level of mini-plate fixation used in fracture mandibles in order to evaluate the structure stability in both convalescence and healing periods. Methods: In the convalescence period, the failure scenario is measured by the relative displacement between two fracture surfaces which should not exceed an acceptable value in order to obtain a good sta

Effects of Nozzle Diameter on Diesel Spray Flames : A numerical study using an Eulerian Stochastic Field Method

The present numerical study aims to assess the performance of an Eulerian Stochastic Field (ESF) model in simulating spray flames produced by three fuel injectors with different nozzle diameters of 100 μm, 180 μm and 363 μm. A comparison to the measurements shows that although the simulated ignition delay times are consistently overestimated, the relative differences remain below 28%. Furthermore,

K2-111 b - a short period super-Earth transiting a metal poor, evolved old star

Context. From a light curve acquired through the K2 space mission, the star K2-111(EPIC 210894022) has been identified as possibly orbited by a transiting planet.Aims: Our aim is to confirm the planetary nature of the object and derive its fundamental parameters.Methods: We analyse the light curve variations during the planetary transit using packages developed specifically for exoplanetary transi

The naked truth about HIV and risk taking in Swedish prisons : A qualitative study

Background: This qualitative study explores former prison inmates’ perceptions and attitudes towards HIV risk inside Swedish prisons. Method: In 2014, eight semi-structured interviews were conducted with former male prisoners to gain a deeper understanding of situations perceived to be associated with risk of HIV transmission. The material gathered from the interviews was analyzed by manifest and

Defining and applying surrogate safety measures and behavioural indicators through site-based observations

This dissertation looks into surrogate safety measures and behavioural indicators that are collected through site-based observations. Surrogate safety measures are defined as measurements that are used to describe the relationship between two road users in a traffic event for the purpose of quantifying the crash probability and/or the potential crash severity in a meaningful way. The main goal of

The role of segmental and suprasegmental information in word-level and sentence-level predictions

IntroductionThis contribution presents recent research results on segmental andsuprasegmental cues to word-internal and sentence-level structure. InSwedish, prosody is tightly connected to morphological and syntacticstructure. For example, every word stem is pronounced with either a low or ahigh tone. The stem tone depends on what follows the stem. Thus, if asingular suffix is connected to the wor

Random Models in Time and Space with Financial, Economics and Engineering Applications : Structural Covariance in Space and Stochastic Variability in Time

In this thesis, we model stochastic processes in time and space. We focus on the processes whose covariance structure is either changing over the time span, or depends on the location in space. We develop models that appropriately describe and analyze such data behaviors in various different fields including finance, economics and engineering. This thesis begins with an introductory section which

ACTH stimulation test and computed tomography are useful for differentiating the subtype of primary aldosteronism

The diagnostic steps for primary aldosteronism (PA) include case screening tests, confirmatory tests, and localization. The aim of this study was to identify useful confirmatory tests and their cut-off values for differentiating the subtype of primary aldosteronism, especially in unilateral PA, such as aldosterone-producing adenoma, and bilateral PA, such as idiopathic hyperaldosteronism. Seventy-

Repetitive glucose spikes accelerate atherosclerotic lesion formation in C57BL/6 mice

Background: A number of epidemiological studies demonstrated that postprandial hyperglycemia is a risk factor for cardiovascular disease in individuals with impaired glucose tolerance. Although several laboratory studies have addressed the plausible causal role of postprandial acute hyperglycemia (glucose spikes) in the development of atherosclerosis, there is little convincing evidence in vivo wh

Sex hjälpverb och deras historia. En grammatikaliseringsstudie : Recension av Mara Bylin: Aspektuella hjälpverb i svenskan. (Acta universitatis Stockholmensis. Stockholm Studies in Scandinavian Philology. New Series 58.) Stockholm: Stockholms universitet (2013).

In her dissertation Aspektuella hjälpverb i svenskan, Maria Bylin investigates the evolution of six aspectual auxiliaries in Swedish (bruka ‘use to’, tendera ‘tend to’, börja ‘begin’, fortsätta ‘continue’, sluta ‘stop’ and hota ‘threaten’). The study is conducted within the framework of grammaticalization, and Bylin’s primary method is to apply so-called auxiliary tests on a historical material co

The Validity of the Screen for Child Anxiety Related Emotional Disorders Revised (SCARED-R) Scale and Sub-Scales in Swedish Youth

We evaluated the clinical utility of the Swedish SCARED-R in child- and adolescent psychiatric outpatients (n = 239) and validated it against Longitudinal Expert All Data (LEAD) DSM IV diagnoses based on the Children’s Schedule for Affective Disorders and Schizophrenia (KSADS) and subsequent clinical work-up and treatment outcome. The SCARED-R total score and subscales had acceptable sensitivity/s
