Objectives: Little is known about the biological processes causing aortic aneurysm rupture. Chronic Chlomydophila pneumoniae infection has been suggested as a possible contributing factor to the development and expansion of abdominal aortic aneurysm (AAA). The importance of infection in AAA may be related to the previous pathogen burden, that is, the number of significant titres of antibodies agai
we present results that provide fundamental insights on how to experimentally tailor the planar defect density and even the crystal structure in III-V metal-particle-seeded nanowires, where zinc blende is the stable bulk crystal structure. We have grown GaP nanowires with metal-organic vapor-phase epitaxy under different conditions: pulsing of the Ga source, and Continuous growth with and without
Broad public contention against nuclear energy can be observed as a new phenomenon in Japanese society after the 2011 Fukushima Daiichi nuclear power plant accident. This study aimed to identify a sufficient explanation about why the emergence of such a protest movement only occurred after the direct experience of a critical event and did not happen before. Discrediting a sole and simple grievance
Global warming and energy shortage have aroused a great interest in climate responsive strategies of vernacular dwellings during recent years. This study focuses on a qualitative analysis of ancient dwellings located in the village of Xinye, in the hot summer and cold winter region of China. Furthermore, a typical ancient dwelling located in the village was selected for assessment of its indoor th
An activity-based vocabulary for Voice Output Communication Aids (VOCAs) was designed and evaluated through a user-centred, iterative design process, using expressions from the Gothenburg Spoken Language Corpus as well as other recorded, natural conversations. The growth and development of the vocabulary, called Phrases, was closely linked to its evaluation. The iterative design process included p
Many insects living in ancient trees are assumed to be threatened as a result of habitat loss and fragmentation. It is generally expected that species in habitats with low temporal variability in carrying capacity have lower degree of dispersal in comparison to those in more ephemeral habitats. As hollow trees are long-lived, species in that habitat are expected to be sensitive to habitat fragment
The growth arrest-specific gene 6 (Gas6) plays a role in pro-atherogenic processes such as endothelial and leukocyte activation, smooth muscle cell migration and thrombosis, but its role in atherosclerosis remains uninvestigated. Here, we report that Gas6 is expressed in all stages of human and mouse atherosclerosis, in plaque endothelial cells, smooth muscle cells and macrophages. Gas6 expression
BACKGROUND: Valid assessments of health-related Quality of Life (HRQL) are increasingly important in chronic, incurable conditions, such as chronic heart failure (CHF). AIMS: To evaluate the psychometric properties of a Swedish version of the Kansas City Cardiomyopathy Questionnaire (KCCQ) in hospitalized patients with decompensated CHF. METHOD AND RESULTS: The KCCQ and SF-36 were administered to
Popular Abstract in Swedish Ämnet för föreliggande avhandling är utveckling av förbränningsmodell för modellering av turbulent icke förblandad förbränning i motorrelaterade tillämpningar. I cylindern i en dieselmotor sker förbränningen under påverkan av och i interaktion med det turbulenta flödesfältet. Det finns härvidlag ett flertal svårigheter för att uppnå acceptabel noggrannhet och acceptablaThree different methods for Reynolds-averaged Navier-Stokes computational fluid dynamics modeling of non-premixed ignition and combustion using tabulated chemistry have been developed. All methods make use of flamelet libraries, where the flamelet auto-ignition process is parameterized using a progress variable. The progress variable parameterization of the auto-ignition chemistry allows for using
Direct ozone (O-3) injection is a promising flue-gas treatment technology based on oxidation of NO and Hg into soluble species like NO2, NO3, N2O5, oxidized mercury, etc. These product gases are then effectively removed from the flue gases with the wet flue gas desulfurization system for SO2. The kinetics and mixing behaviors of the oxidation process are important phenomena in development of pract
Maturation stage ameloblasts of rodents express vacuolar type-H-ATPase in the ruffled border of their plasma membrane in contact with forming dental enamel, similar to osteoclasts that resorb bone. It has been proposed that in ameloblasts this v-H-ATPase acts as proton pump to acidify the enamel space, required to complete enamel mineralization. To examine whether this v-H-ATPase in mouse amelobla
Many of the core proteins in Photosystem II (PS II) undergo reversible phosphorylation. It is known that protein phosphorylation controls the repair cycle of Photosystem II. However, it is not known how protein phosphorylation affects the partial electron transport reactions in PS II. Here we have applied variable fluorescence measurements and EPR spectroscopy to probe the status of the quinone ac
The carrot psyllid (Trioza apicalis) is a serious pest in carrot-growing areas in northern and parts of central Europe. The psyllids overwinter as adults on conifers and during summer feed and lay eggs on carrot plants (Daucus carota ssp. sativus), thereby destroying the crop. To investigate the migratory capabilities and preferences for different shelter plant species of the carrot psyllid, we ma
Popular Abstract in Swedish De fyra studier som ingår i denna avhandling är gjorda för att undersöka eventuella oönskade effekter av läkemedel på näthinnan. Näthinnan är en del av det centrala nervsystemet och känslig för toxiska substanser. För att skydda näthinnan så finns två barriärer – en yttre och en inre blod–näthinne- barriär. Dessa barriärer består av strukturer som håller samman celler iThe adverse effects of drugs in the eye are not easily detected, and the underlying pathogenesis not fully understood. The effects of four different kinds of drugs have been investigated in the rabbit eye, using electroretinography, ocular examination and histochemical methods. Rifabutin is a broad spectrum antibiotic with known ocular adverse effects (corneal opacities, uveitis and vascular ret
BACKGROUND: Individuals with low income have poorer health and should, therefore, have higher health expenditure than people with high income particularly in countries with a universal health care system. However, it has been discussed if social inequities in health diminish with age and we, hence, aimed to analyse this question. METHODS: We performed an age stratified cross-sectional analysis usi
The first stories about Kluskap, the culture hero of the Mi’kmaq in eastern Canada, were written down at the end of the 19th century. The romantic epoch and the environmental failures of industrialism had generated a growing interest for the “Indian”, who seemed to inherit the continent’s authentic “poetry of the Volk” and harbour deep wisdom about nature. The first written literature about Kluska
Background: ABO genotyping is complicated by the remarkable diversity at the ABO locus. Recombination or gene conversion between common alleles may lead to hybrids resulting in unexpected ABO phenotypes. Furthermore, numerous mutations associated with weak subgroups and nondeletional null alleles should be considered. All known ABO genotyping methods, however, risk incorrect phenotype predictions
The aim of this study was to explore older patients' experiences of participation in the prescription process of mobility devices. The study was conducted in two Swedish municipalities and was a qualitative study, based on the focus group interview methodology of Merton et al (1990). In order to recruit a sample fulfilling both homogeneity and heterogeneity criteria, occupational therapists and p
The aim of the study was to outline whether the influence by lifestyle factors on serum lipids was modified by the hormonal situation in middle-aged women. Six thousand nine hundred eight women, aged 50 to 59 years, participated in a health assessment program, including a serum lipid profile evaluation. The women were grouped according to their hormonal status into premenopausal (PM) (n = 492), po
BACKGROUND: In health economics, health is regarded as part of an individual's human capital. As such it depreciates over time, and investments in health are made in order to keep the stock of health capital at the desired level. Using this framework for analysis of health-related behaviour and Swedish panel data, we examined whether the presence of asthma or allergy affects perceived health and i
