Popular Abstract in Swedish Den enorma variationen av beteenden och utseenden som återfinns i djurriket har i alla år fascinerat och länge förbryllat biologer. Rovdjurens skoningslösa utgallring är en av de stora drivkrafterna bakom evolutionen av alla dessa karaktärsdrag. Rovdjuren är såklart även en viktig strukturerande kraft i sötvattensmiljöer och har där lett till utvecklingen av mängder av The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. In this thesis I investigate both the direc

Popular Abstract in Swedish Hemolytiskt uremiskt syndrom (HUS) och trombotiskt trombocytopen purpura (TTP) är allvarliga sjukdomar hos barn och vuxna. HUS kännetecknas av mikroangiopatisk hemolytisk anemi (blodbrist med nedbrytning av röda blodkroppar), trombocytopeni (låga blodplättar) och akut njursvikt. Det är den vanligaste orsaken till akut njursvikt hos barn. Typisk HUS utlöses av tarminfektThis study investigated the pathogenesis of hemolytic uremic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP). (1) The relative roles of lipopolysaccharide and Shiga-like toxin-2 were studied in a mouse model of Escherichia coli O157:H7 infection. Both factors were found to be important for the virulence of the strain and contributed in an additive manner. The mouse model mimicked cert

Leukotrienes are membrane derived bioactive lipids that play an important role in immune responses by initiating and maintaining the inflammatory responses. Leukotriene B4 (LTB4) released at the site of an inflammatory response attracts, activates and prolongs the life of leukocytes and lymphocytes. LTB4 can bind to two recently cloned cell surface G-protein coupled receptors named BLT1 and BLT2.

This study investigates the topic of forgiveness of sins in the mission of the historical Jesus. Gospel material that pertains to the question is authenticated by the use of criteria for historicity and interpreted within the wider context of first-century Judaism as part of a broader reconstruction of Jesus’ career as a healer and prophet. Questions posed and answered concern the historical plaus

Techniques for interfacing the nervous system using chronically implanted electrodes are turning into invaluable tools for neurophysiological research and treatment of neurological disorders. These methods have been developed and refined over the last decades. However, they still suffer from deteriorating electrical capabilities and the fact that they inevitably damage the tissue into which they a

Although several models have been suggested in the literature to describe the relationship between learning and forgetting, this relationship is still not fully understood. This paper proposes the Depletion-Power-Integration-Latency (DPIL) model, which assumes that performing a task repetitively depletes the available encoding resources for that task. The DPIL model fitted five empirical datasets

Contemporary cognitive science challenges the idea about the human brain as a kind of computor. Instead the importance of the body for our way to understand and interact with the world has come into focus. Theories about the ”situated” and ”embodied” character of human cognition have entailed that notions like action, consciousness, and intersubjectivity have gained renewed scientific interest. On

Changing Landscapes and Persistent Places is a study of the cultural landscape on the Bjäre peninsula in northwest Skåne. The many Bronze Age remains that give the landscape its distinctive character are the starting point for an attempt to increase our understanding of the historical depth of today’s landscape. The two perspectives of “landscape” and “places” carry the discussion forward, almost

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

We present a combination of semiempirical quantum-mechanical (SQM) calculations in the conductor-like screening model with the MM/GBSA (molecular-mechanics with generalized Born and surface-area solvation) method for ligand-binding affinity calculations. We test three SQM Hamiltonians, AM1, RM1, and PM6, as well as hydrogen-bond corrections and two different dispersion corrections. As test cases,

This study concerns an arctic marine environment that was contaminated by actinide elements after a nuclear accident in 1968, the so-called Thule accident. In this study we have analyzed five isolated hot particles as well as sediment samples containing particles from the weapon material for the determination of the nuclear fingerprint of the accident. We report that the fissile material in the hy

Biomedicine is typically defined as the branch of medicine that is based on the principles of biology and biochemistry. A central tenet for biomedicine is the notion of disease and therapeutic specificity, i.e. the idea of tailored treatments for discrete disorders underpinned by specific pathologies. The present paper is concerned with how notions of disease and therapeutic specificity guide biom
