Sammanfattning : Molecular biology has become an integral part of the diagnosis of infectious diseases. Recently, quantitative real-time PCR (QPCR) methods (often in the form of so-called TaqMan® systems) have been developed for the diagnosis of a wide range of infectious diseases; these techniques found valuable clinical application in the diagnosis and evaluation of progress and therapeutic success of viral diseases.

2. Genomic and morphological diversity of marine planktonic diatom-diazotroph associations : a continuum of integration and diversification through geological time
Sammanfattning : Symbioses between eukaryotes and nitrogen (N2)-fixing cyanobacteria (or diazotrophs) are quite common in the plankton community. A few genera of diatoms (Bacillariophyceae) such as Rhizosolenia, Hemiaulus and Chaetoceros are well known to form symbioses with the heterocystous diazotrophic cyanobacteria Richelia intracellularis and Calothrix rhizosoleniae.

Sammanfattning : Di-nitrogen (N2) fixers, also called diazotrophs, are able to reduce atmospheric N2 into bioavailable nitrogen, giving them an advantage in open ocean regions with low dissolved inorganic nitrogen concentrations. The focus of this thesis are three lineages of symbiotic heterocystous filamentous types (het-1, het-2 and het-3), that associate with several genera of microalgae called diatoms (collectively referred to as Diatom Diazotroph Associations, DDAs).

Sammanfattning : Community-acquired pneumonia (CAP) is a major cause of morbidity and mortality worldwide. Although there is wide variation in the microbial etiology, CAP may manifest with similar symptoms, making institution of proper treatment challenging. LÄS MER
5. Mechanisms of Osseointegration: Experimental Studies on Early Cellular and Molecular Events in vivo
Sammanfattning : The early cellular and molecular activities determining the early tissue response and bone formation at bone/implant interface are not fully understood. The general aim of the current thesis was to develop a model for studying the early molecular and cellular activities in different bone types, and in response to different implant surface properties.
