    Abstract : One of the most distinctive features of eukaryotic chromosomes is the bundling of DNA together with functionally associated RNA and proteins in chromatin. This allows huge amounts of DNA to be packed inside the very tiny space of the nucleus, and alterations in the structure of chromatin enable access to the DNA for transcription (“reading” genes by production of RNA copies).

  4. 2. The EGF-like Modules of Anticoagulant Protein S. Studies of Ca2+ binding and module interactions

    Author : Yvonne Stenberg; Malmö Klinisk kemi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymology; Proteins; Klinisk kemi; Clinical chemistry; calcium binding; Protein S; EGF-like module; Proteiner; enzymologi;

    Abstract : Protein S functions as a cofactor to activated protein C (APC) in the degradation of factors Va and VIIIa. In plasma protein S circulates in two forms; 30-40 % circulates as free protein S molecules while the remaining 60-70 % exists in a 1:1 complex with C4b-binding protein (C4BP). Only the free form of protein S functions as a cofactor to APC. READ MORE

    Abstract : This thesis presents studies of semi-Markov models for insurance and option rewards. The thesis consists of the introduction and six papers. The introduction presents the results of the thesis in an informal way.In paper A, a general semi-Markov reward model is presented. READ MORE

  6. 4. Ear and hearing problems in Turner syndrome

    Abstract : Turner Syndrome is a common chromosomal disorder and affects approximately one in every 2000 newborn girl. The syndrome is defined as a total (45,X) or partial loss of the second sex chromosome in combination with the typical characteristic features, which are short stature (less than 150 cm), absent estrogen production due to ovarian dysgenesis, with failure to enter puberty spontaneously and infertility.

  7. 5. Viral wheeze and risk factors for childhood asthma : an evaluation of clinical, immunological and genetic factors

    Author : Katarina Stenberg Hammar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It’s not fully understood why some children wheeze with viral infections, and why some develop severe asthma. In this study we compared two study groups; children presenting with acute wheeze (AW) before the age of four and age-matched healthy controls (HC), and we investigated factors that might contribute to increased vulnerability for airway infections and risk of later asthma development.
