Environmental change may affect predator-prey interactions in lakes through deterioration of visual conditions affecting foraging success of visually oriented predators. Environmental change in lakes includes an increase in humic matter causing browner water and reduced visibility, affecting the behavioural performance of both piscivores and prey. We studied diurnal patterns of prey selection in p

Individuals with type 1 diabetes (T1D) have a 2 to 3-fold increased risk for cardiovascular disease compared to non-diabetic subjects. Exposure to a broad panel of risk factors in childhood may cause vascular damage with potentially long-term consequences for cardiovascular morbidity. The aims of the studies were to investigate in young patients with T1D whether: frequency of acute infections co

Popular Abstract in Swedish Hjärtat pumpar blod genom ett nätverk av blodkärl, vilket för ut syre och näringsämnen till organen och för tillbaka restprodukter som bryts ned eller utsöndras från kroppen. När hjärtat pumpar byggs det upp ett tryck som driver blodet genom kärlsystemet, från artärter till vener via ett förgrenat nät av kapillärer, som svarar för utbytet med vävnadsvätskorna. BlodflödeSmooth muscle cells residing in the blood vessel media are constantly exposed to mechanical forces exerted by the intraluminal pressure. The smooth muscle senses and adapts to mechanical forces by activation of multiple signaling pathways and cytoskeletal rearrangements. Stretch of the vascular wall is therefore an important factor that controls smooth muscle cell phenotype and function. The goal

Population-based studies on the epidemiology of primary sclerosing cholangitis (PSC) are sparse. The aim of the present study was to investigate prevalence and temporal trends in the incidence of PSC 1992-2005 in an adult population in Vastra Gotaland, a region in southern Sweden with a defined population of about 1.5 million. Patients with PSC aged 18 years or above were identified through a comp

The healthcare sector is one of the fastest growing economic sectors of today. The medical device domain is one part of that sector. An increasing part of functionality in medical devices and systems is implemented in software and many features should not be possible to implement without software. The use of medical software is an inherent risk to the patient and the outcome of a failure can vary

Background: Cerebral ischemia activates both the innate and the adaptive immune response, the latter being activated within days after the stroke onset and triggered by the recognition of foreign antigens. Methods: In this study we have investigated the phenotype of antigen presenting cells and the levels of associated major histocompatibility complex class II (MHC II) molecules in the postischemi

For almost forty years the seemingly harmless term “postmodern” has sown discord and ruffled feathers in the intellectual world. Mere sight of the term has caused some commentators to see red in more than one sense: “postmodernism” for them embodies the utter degeneracy of the 1960s Left. For their part, more than a few commentators on the left have associated the term with the neoliberal climate

Popular Abstract in Swedish Råttans urinblåsa har studerats ur olika aspekter, sedan antingen ett standardiserat avflödeshinder åstadkommits eller hälften av urinblåsans nervförsörjning avlägsnats. Avflödeshindret har åstadkommits genom att en silkestråd knutits runtom urinröret så att det försnävats. Genom att en knappt mm-vid metallstav knutits om samtidigt och sedan avlägsnats, har graden av av

Popular Abstract in Swedish Typ 2 diabetes (även kallat sockersjuka eller åldersdiabetes) är en av våra vanligaste förekommande folksjukdomar och ungefär 5% av alla människor beräknas ha sjukdomen. Typ 2 diabetes karakteriseras av kroniskt förhöjda blodsocker-nivåer som orsakas dels av en oförmåga hos insulin att befrämja blodsockerupptag i dess målvävnader, fett och muskel, och dels av en oförmågType 2 diabetes mellitus is a multifactorial disorder characterized by chronic hyperglycemia resulting from pancreatic dysfunction and insulin resistance. It is a common disorder with a complex pattern of inheritance, likely to reflect the influence of multiple genetic and environmental factors on the diabetes risk. The aim of thesis was to identify genetic risk factors for type 2 diabetes. In a g

Popular Abstract in Swedish Immunsystemet utgörs av de celler och molekyler i kroppen som har till uppgift att skydda oss mot angrepp av sjukdomsframkallande bakterier, virus och parasiter. Dessa patogener hindras först och främst av fysiska barriärer såsom hud, slemhinnor och mag/tarm kanalen. Patogener som har lyckats ta sig igenom dessa barriärer, möter härnäst immunsystemets första försvarslinThis thesis is based on work studying the immunoregulatory mechanisms that govern the balance between activation and inactivation of T lymphocytes. Most of the work has been carried out in an experimental system using a T cell receptor (TCR-Vb3) transgenic mouse strain to obtain a homogenous T-cell population and utilizing the properties of bacterial superantigens to induce T cell responses and un

Popular Abstract in Swedish Profeterna legitimerar i regel sitt budskap genom att inleda med den s k budbärarformeln: Så säger Herren. Därmed menar de att Herren talar genom dem. De utgör endast hand stämma. De budskap, som framförs under de knappt 400 år som Gamla testamentets skriftprofeter verkar, är emellertid oerhört mångformiga. Och detta gäller inte bara innehållet utan också utformning, spWhy does the Lord say thus? Prophets, Contexts, Rhetoric A Comparison Between Amos and Malachi When the prophets preached their messages they authorized their words by the old messenger formula "Thus says the Lord". The import of these words was to emphasize that the prophet was only the mouthpiece of the Lord. However, the prophetic literature of the Old Testament is highly varied in its scope a

Sverige är ett utpräglat småföretagarland och mätt i antal bedrivs en klart övervägande del av företagen som enskild näringsverksamhet. Till skillnad från aktiebolag och andra juridiska personer, som hänför alla inkomster till inkomstslaget näringsverksamhet, ska inkomster eller utgifter för fysiska personer hänföras till endera av inkomstslagen näringsverksamhet, tjänst eller kapital. AvhandlingeSweden is a typical small-business country and, based on the numbers, a clear majority of the companies operate as sole traders. Unlike limited companies and other legal entities, which classify all income as business income, the income or expenditures of private persons are classified as either business, service or capital income. The main objective of this thesis is to systematically examine the

Popular Abstract in Swedish I mitt arbete som neuropsykolog vid minnesmottagningen på psykogeriatriska kli¬niken (numera VO kognitiv medicin) vid Universitetssjukhuset i Lund har jag träffat många patienter som beskrivit besvärande minnessvårigheter i sin vardag. Patienterna berättade om svårigheter att lära sig nya rutiner på arbetet, att komma ihåg namn eller var de hade lagt sina saker. Många aThe overall aim of this thesis was to enhance the understanding of patients with subjective memory complaints. The thesis is based on three empirical studies examining middle-aged and young old (< 70 years) non-demented patients assessed at a memory clinic. In the first study the personality characteristics of the patients were compared with a Swedish normative sample. The patients scored higher o

The post-failure convergence of the shortest path routing (SPR) protocols used in IP networks can be too slow to meet the restrictive requirements (i.e., maximum allowable delay, jitter, etc.) of the multimedia services and therefore new restoration mechanisms combined with IP routing are of interest. The paper addresses optimization of three potential rerouting mechanisms based on the IP fast rer

Popular Abstract in Swedish Proteiner är den huvudsakliga beståndsdelen i levande celler. Proteiner består av långa kedjor av aminosyror som sitter ihop med peptidbindningar och vecklar ihop sig till komplicerade tre dimensionella strukturer. Proteiner är involverade i praktiskt taget alla mekanismer och funktioner i cellen. När man studerar hela proteinsammansättningen i t.ex. ett organ, en speciMembrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. a cell or a tissue, at a certain time point and "proteomics" is the large scale study of these prote

The role of accountants in organizations is intriguing in the current context of the broad changes in the profession observed by many. Mainly because of technological advancements, what has previously required a considerable amount of time and effort, i.e. bookkeeping & reporting, has been assumed to ‘just happen’ easily, with a corollary that it should not be taken for granted, that the accou

Popular Abstract in Swedish Hur man undviker att bli trakasserad på flicksländornas vis Tidigare forskningsresultat har visat att hos honor i de flesta djurarter begränsas fortplantningkapacitet av hur mycket tid och energi de kan lägga på sina avkommor. Hos hanar, å andra sidan, begränsas fortplantningskapacitet av hur många honor de kan para sig med. Då kan man dra slutsatsen att hanar ska förs
