11. Evasion and Attack: Structural Studies of a Bacterial Albumin-binding Protein and of a Cephalosporin Biosynthetic Enzyme
Sammanfattning : This thesis describes the crystal structures of two proteins in the context of combatting bacterial infections. The GA module is a bacterial albumin-binding domain from a surface protein expressed by pathogenic strains of the human commensal bacterium Finegoldia magna. LÄS MER
12. Synthesis of Conformationally Restricted Oligosaccharides
Sammanfattning : Gangliosides are sialic acid-containing glycosphingolipids that often are present in increased amounts on tumor cells. Since the gangliosides are hydroxy-acids, they can form lactones. The lactones have been suspected to be more immunogenic than the open forms, but are in practise poor immunogens due to their ease of hydrolysis. LÄS MER
13. Prognostic assessment in community acquired pneumonia
Sammanfattning : Community acquired pneumonia (CAP) is the most commonly occurring infectious disease that requires hospital admission. CAP affects mainly, the youngest, the oldest, the poorest and the sickest. Annual incidence is 5-12 per 1000 adults. Between 20% and 40% of patients with CAP need in-hospital treatment. LÄS MER
14. Antibiotic Resistance in Wastewater : Methicillin-resistant Staphylococcus aureus (MRSA)and antibiotic resistance genes
Sammanfattning : A large part of the antibiotics consumed ends up in wastewater, and in the wastewater the antibiotics may exert selective pressure for or maintain resistance among microorganisms. Antibiotic resistant bacteria and genes encoding antibiotic resistance are commonly detected in wastewater, often at higher rates and concentrations compared to surface water. LÄS MER
15. Synthesis and biological evaluation of Bicyclic β-Lactams and 2-Pyridinones : Pilicides Targeting Pilus Biogenesis in Pathogenic Bacteria
Sammanfattning : New methods have been developed for the synthesis of bicyclic β-lactams and 2-pyridinones by combining acyl Meldrum’s acids and Δ2-thiazolines. The 2-pyridinones were synthesised both in solution using conventional heating or microwave assisted heating as well as by solid supported chemistry. LÄS MER
