A Clinical and Genetic Study of Psoriatic Arthritis

Psoriatic arthritis (PsA) is an inflammatory joint disease related to psoriasis. PsA has a heterogeneous structure, indicated by various manifestations like mild mono-oligoarthritis or very severe, erosive and damaging polyarthritis. Measurable inflammatory activity isn’t necessarily prominent. The aetiology is not known but

Accessory factors for ribosomal assembly

The assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into ribosomal subunits (30S and 50S) is actually a complex process. Transcription of rRNA needs antitermination proteins and the main transcripts are processed by ribonucleases. R-proteins and rRNAs are chemically altered, the

Dynamics of the Bacterial Genome: Rates and Mechanisms of Mutation

Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. typhimurium.
