1. Ehrlichia in animals and humans
Sammanfattning : Ehrlichia phagocytophila is a tick-borne pathogen of domestic animals, which has recently been acknowledged also as a human pathogen. It is a strictly intracellular bacterium, infecting granulocytes of the host, sometimes resulting in clinical disease - granulocytic ehrlichiosis - with manifestations ranging from mild flu-like conditions to severe infections with multi-organ failure and death.

2. Animals and Humans : Human-animal interaction in northern Sweden during the late glacial and postglacial time
Sammanfattning : When the last remnant of the Weichsel glacier melted in northern Sweden, around 7000 BC, pioneer settlers entered virgin land, following their prey, which in turn followed the vegetation dispersion. Some of the settlers derived from the east and the northeast and spread from the Russian taiga, through Finland and into northern Sweden, the study area for this thesis. LÄS MER
3. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT
Sammanfattning : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. LÄS MER
4. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans
Sammanfattning : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. LÄS MER
5. Origins and Adaptation in Humans : A Case Study of Taste and Lifestyle
Sammanfattning : In this thesis, I use population genetics and statistical approaches to investigate early human demography, infer local adaptation in diverse sets of populations, and study the genetic basis for taste perception.In the first paper, I examine the genomic evidence for a severe bottleneck, which has been suggested based on paleontological and climate studies to coincide with the emergence of anatomically modern humans.
