1. Recognition and clearance of Streptococcus pneumoniae by the innate immune system
Sammanfattning : Streptococcus pneumoniae (the pneumococcus) is a major human pathogen causing diseases such as pneumonia, bacteremia or meningitis and constitutes a leading cause of morbidity and mortality worldwide. The pathogenesis of pneumococcal disease and the mechanisms of recognition and clearance of S. LÄS MER
2. Secondary plant metabolites as defence against herbivores and oxidative stress : Synthesis, isolation and biological evaluation
Sammanfattning : In this thesis the isolation, synthesis and biological evaluation of natural defense compounds against herbivores or oxidative stress is discussed.The first part concerns the metabolites of platyphylloside ((5S)-5-hydroxy-1,7-bis-(4-hydroxyphenyl)-3-heptanone-5-O-β-D-glucopyranoside), a phenolic glucoside found in birch (Betula pendula) that possess digestibility inhibiting activity in herbivores.

3. Perfusion computed tomography of the liver
Sammanfattning : Background: Perfusion CT (P-CT) is a relatively new imaging technique that permits the visual and quantitative assessment of the micro- and macrocirculation of a target organ and focal lesions. P-CT has shown promising results in the evaluation of hyper-vascular tumors such as hepatocellular carcinoma (HCC). LÄS MER
4. Cysteine biosynthesis in Mycobacterium tuberculosis as potential drug target
Sammanfattning : The bacterium Mycobacterium tuberculosis is the underlying cause of tuberculosis, one of the most devastating infectious diseases, causing 1.4 million deaths in 2015. LÄS MER
5. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression
Sammanfattning : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. LÄS MER
