21. The transferrin polymorphism : population genetics and associations with reproductive hazards and disease
Sammanfattning : Human serum transferrin (TF) carries iron from the intestine, reticuloendothelial system and liver parenchymal cells to proliferating cells in the body. TF is highly polymorphic, and previous findings of associations between TF types and reproductive hazards in different species suggest that the TF polymorphism may be involved in natural selection and susceptibility to disease.

22. Ticks - ecology, new hazards, and relevance for public health
Sammanfattning : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

23. Long-term health hazards from diagnostic X-ray exposure
Sammanfattning : Medical imaging is an important function in the diagnosis and management of disease and its use have been increasing with technological advancements. A large part of medical imaging uses ionizing radiation as medium for imaging although it does pose potential risks to the patient. LÄS MER
24. Multiple Time Scales and Longitudinal Measurements in Event History Analysis
Sammanfattning : A general time-to-event data analysis known as event history analysis is considered. The focus is on the analysis of time-to-event data using Cox's regression model when the time to the event may be measured from different origins giving several observable time scales and when longitudinal measurements are involved.
