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. 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
3. 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
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.

Sammanfattning : The human polyomaviruses BKV and JCV are endemic and infect > 70% of population worldwide. Primary infections occur during childhood and are largely subclinical. Following primary infection, both viruses persist as latent infections in the kidneys and B lymphocytes. LÄS MER
