2. 1. Adaptation of Helicobacter pylori Adherence Properties in Promotion of Host Tropism and Inflammatory Disease

   Author : Marina Aspholm; Rino Rappuoli; Umeå universitet; []
   Keywords : H. pylori; BabA; SabA; adhesin; blood group antigens; sialylated; phase variation; hemagglutination; selectin; adaptation; odontologi; Odontology;

   Abstract : Being among the most prevalent of persistent infectious agents in humans worldwide, Helicobacter pylori induces chronic inflammation (gastritis), which may progress to peptic ulceration and stomach cancer. The ability to adhere to the gastric mucosa is considered to be both a colonization and virulence property of H. pylori. For adherence, H. READ MORE

4. 2. Human adenoviruses : new bioassays for antiviral screening and CD46 interaction

   Author : Emma Andersson; Göran Wadell; Sigvard Olofsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adenovirus; CD46; hemagglutination; antiviral; small molecule; screening; Virology; Virologi;

   Abstract : Adenoviruses are common pathogens all over the world. The majority of the population has at some point been infected with an adenovirus. Although severe disease can occur in otherwise healthy individuals an adenovirus infection is most commonly self limited in these cases. READ MORE

5. 3. Synthesis and biological evaluation of Bicyclic β-Lactams and 2-Pyridinones : Pilicides Targeting Pilus Biogenesis in Pathogenic Bacteria

   Author : Hans Emtenäs; Ulf Nilsson; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; β-lactam; 2-pyridinone; 2-pyridone; Meldrum’s acid; Δ2-thiazoline; solid-phase synthesis; microwave assisted synthesis; antibacterial; pili; pilicide; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Abstract : 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. READ MORE

6. 4. Antiadhesive agents targeting uropathogenic Escherichia coli : Multivariate studies of protein-protein and protein-carbohydrate interactions

   Author : Andreas Larsson; Jan Kihlberg; Fredrik Almqvist; Mats Larhed; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Antibacterial; pili; antiadhesive agents; structure based design; statistical molecular design; 2-pyridone; amino acid derivative; galabiose; enaminone; SPR; ELISA; QSAR; Organisk kemi; Organic chemistry; Organisk kemi; organisk kemi; Organic Chemistry;

   Abstract : This thesis describes studies directed towards development of novel antiadhesive agents, with particular emphasis on compounds that prevent attachment of bacteria to a host-cell. Three different proteins involved in the assembly or function of adhesive pili in uropathogenic Escherichia coli have been targeted either by rational structure based design or statistical molecular methods.

7. 5. New apheresis techniques in transplantation

   Author : Gunilla Kumlien; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : The shortage of organs for transplantation is a global problem and therefore it is of outmost importance to increase the number of donations and improve long term graft survival. As an effort to increase kidney donations, living kidney donors are being increasingly used and both patient and graft survival is superior after living donation compared with kidney transplantations using organs from deceased donors.
