Background Impaired muscarinic receptor-mediated vasodilation is an important feature of early atherosclerosis. Earlier studies on apolipoprotein E-knockout mice (apoE-KO) mice suggested adverse effects of Chlamydia pneumoniae infection on the endothelial vasomotor responses of aortas to the muscarinic agonist methacholine. Using additional aorta samples the present study investigated the response
infection with hepatitis B virus (HBV) is a major global health problem. Transmission is mainly blood-borne, although the route of infection during horizontal transmission in childhood is unclear. Nosocomial outbreaks of HBV have been widely reported, but have mainly focused on blood-borne transmission. There is Limited knowledge of the viral Load Levels in other body fluids. In the present study,
A new implantable electrocatalytic glucose sensor for subcutaneous glucose monitoring has been fabricated by immobilizing glucose oxidase on a chemically modified carbon fiber. The sensor was inserted subcutaneously on a male spraguely rat without any incision after dipping the microsensor in the rat's serum for 3 days. The so called "stained" microsensor, operated in the amperometric mode with an
The mitochondrial oxidative phosphorylation system in plants possesses a variety of alternative pathways that decrease respiratory ATP production. These alternative pathways are mediated by three classes of bypass proteins: the type II NAD(P) H dehydrogenases (which circumvent complex I of the electron transport chain), the alternative oxidases (AOXs; which circumvent complexes III and IV) and the
Popular Abstract in Swedish Avhandlingen handlar om naturföreställningar i resereklam och bland re-senärer. Syftet var att analysera hur natur framställs i reklambilder för resor, vad reklamens framställning av natur har för betydelse för vad resenärer vill uppleva och upplever i samband med sin resa samt med vilka argument och bilder resenären själv väljer att återskapa upplevelserna av sin resa It is commonly believed that we live in a culture that is increasingly permeated by visual images. One category of images that we encounter everyday in different media, and that constitutes a large and growing part of media content, is advertisements. Advertisements also have a specific purpose and the images represent, make meaning of, and convey sentiments about phenomena. In this dissertation,
Whole-lake additions of dissolved inorganic C-13 were used to measure allochthony (the terrestrial contribution of organic carbon to aquatic consumers) in two unproductive lakes (Paul and Peter Lakes in 2001), a nutrient-enriched lake (Peter Lake in 2002), and a dystrophic lake (Tuesday Lake in 2002). Three kinds of dynamic models were used to estimate allochthony: a process-rich, dual-isotope flo
Plants of the partially self-incompatible perennial herb Brassica cretica, derived from contralled cross- and self-pollinations within each of seven populations, were raised under uniform conditions and scored for two measures of developmental stability, flower asymmetry (quantified as the difference in length and width between opposite petals) and cotyledon asymmetry (quantified as the difference
Premixed turbulent flame-based technologies are rapidly growing in importance, with applications to modern clean combustion devices for both power generation and aeropropulsion. However, the gain in decreasing harmful emissions might be canceled by rising combustion instabilities. Unwanted unsteady flame phenomena that might even destroy the whole device have been widely reported and are subject t
The International Stem Cell Initiative characterized 59 human embryonic stem cell lines from 17 laboratories worldwide. Despite diverse genotypes and different techniques used for derivation and maintenance, all lines exhibited similar expression patterns for several markers of human embryonic stem cells. They expressed the glycolipid antigens SSEA3 and SSEA4, the keratan sulfate antigens TRA-1-60
An experimental study was performed to investigate the dependency of particle size on the deposition rate. Polystyrene latex particles of two radii (0.23 and 0.38 mum) were deposited onto a glass surface covered with indium-tin oxide. Reduced deposition efficiency was observed for the larger particles, although an increase in the deposition efficiency was seen as that the diffusion boundary layer
Popular Abstract in Swedish Det svenska samhället har förändrats mycket genom invandring under de senaste årtiondena. Många barn i Sverige har idag ett annat modersmål än svenska. De flesta barn tillägnar sig svenska utan problem, medan så inte är fallet för vissa barn. Dessa skillnader har diskuterats, och olika förklaringar till detta har framhållits, till exempel bristfällig exponering för svenThe aim of this thesis was to provide both epidemiological and linguistic data on bilingual children with language impairment (LI), since few data on this group exist. Data from 438 bilingual and monolingual children, referred over a period of 12 months, were compared in the first epidemiological study. The results showed that the bilingual children with suspected LI were referred significantly l
The Swedish Air Navigation Service Provider in cooperation with the University of Lund aims at developing a model for supporting continuous improvements and learning focusing on safety in air traffic control. This paper focuses on relationships between the safety culture and the psychosocial working environment. These areas were studied using questionnaires at the two main air traffic control cent
Popular Abstract in Swedish För att kunna förstå och bedöma exponeringen av kemikalier i miljön, i det här fallet PolyBromeradeDiphenylEtrar (PBDEer), behövs kunskap om källor och flöden från teknosfären till ekosystemen. PBDEer är bromerade flamskyddsmedel som bl a sätts till olika plastmaterial i elektronikanvändning för att förhindra brand. Det används globalt i miljontals kilo och presenteras I have studied the sources, long range transport, and rates of flow of polybrominated diphenyl ethers (PBDEs), from the technosphere to the Baltic ecosystems. PBDEs are mainly used in polymers, which are applied in electrical equipment to prevent overheating or flashover and are produced in large quantities. PBDEs have become widely spread in the environment, where they are able to accumulate in b

Thus seven monodeoxygenated analogues of 2-(Trimethylsilyl)ethyl betha-lactoside were synthesiszed. Silver silcate was successfully used in betha 1-4 coupling of 2- and 3-deoxy glucosides to to acetobromogalactose. By similar means, the monodeoxylactosyl brom
At present, relatively little is known about the relationship between bank credit allocation and economic growth. It seems clear that the structural characteristics of the banking system are significant factors influencing long-run allocation of credit across real sectors of the economy as well as across financial institutions. The purpose of this study is to examine the relationship between chang
Objective. The aim of the study was to survey existing research about fatigue among older people with chronic non-malignant pain. Method. A structured literature review was carried out using the Medline database. The terms ‘fatigue’ and ‘tiredness’ were used synonymously. These subject headings were combined with pain. A literature search was made in 2004 and included articles back to 1995. Resu
Popular Abstract in Swedish Blodet består av olika typer av celler med olika funktioner. De röda blodkropparna transporterar syre till alla delar av kroppen, blodplättar stoppar blödningar och en rad olika vita blodkroppar försvarar oss från olika typer av angrepp från till exempel virus eller bakterier. Generellt för alla dessa olika typer av celler är att de är kortlivade och måste ersättas kontMature blood cells are crucial for life, but they have a short lifetime and thus have to be replaced. These mature blood cells are produced by lineage restricted progenitors, which themselves are generated by rare multipotent hematopoietic stem cells (HSCs) in a highly dynamic process called hematopoiesis. In addition to the ability of HSCs to generate all blood cell lineages, they possess the uni
Typically, a significant fraction of phosphorus in soils is composed of organic phosphates, and this fraction thus plays an important role in the global phosphorus cycle. Here we have studied adsorption of monomethyl phosphate (MMP) to goethite (alpha-FeOOH) as a model system in order to better understand the mechanisms behind adsorption of organic phosphates to soil minerals, and how adsorption a
Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is an enzyme that is produced by inflammatory cells (macrophages, T-lymphocytes and mast cells) and hydrolyzes oxidized phospholipids in LDL. Several epidemiology studies indicate that Lp-PLA(2) appears to be an independent marker of cardiovascular risk. This study was conducted to define the distribution of Lp-PLA(2) in a large population-base
