1. Telomere length : dynamics and role as a biological marker in malignancy
Sammanfattning : Telomeres are protective structures at the end of our chromosomes, composed of multiple repeats of the DNA sequence TTAGGG. They are essential for maintaining chromosomal stability by preventing damage and degradation of the chromosome ends. LÄS MER
2. Estimation of wood fibre length distributions from censored mixture data
Sammanfattning : The motivating forestry background for this thesis is the need for fast, non-destructive, and cost-efficient methods to estimate fibre length distributions in standing trees in order to evaluate the effect of silvicultural methods and breeding programs on fibre length. The usage of increment cores is a commonly used non-destructive sampling method in forestry. LÄS MER
3. Variation in length of proteins by repeats and disorder regions
Sammanfattning : Protein-coding genes evolve together with their genome and acquire changes, some of which affect the length of their protein products. This explains why equivalent proteins from different species can exhibit length differences. LÄS MER
4. Evolution of Spur Length in a Moth-pollinated Orchid
Sammanfattning : There is considerable evidence that pollinator shifts can explain many differences in flower morphology between closely related plant species, but the extent to which pollinator shifts can explain the maintenance of among-population variation in floral traits within species is poorly known. In this thesis, I combined comparative and experimental approaches to examine the evolution of floral traits in the moth-pollinated orchid Platanthera bifolia. LÄS MER
5. Telomere length as prognostic parameter in chronic lymphocytic leukemia
Sammanfattning : B-cell chronic lymphocytic leukemia (B-CLL) is the most common leukemia among the adult population in western countries and accounts for 30-40% of all leukemias. With survival time ranging from months to decades, the clinical course of individual CLL patients is highly variable. LÄS MER
