2. 1. Enterohemorrhagic Escherichia coli, EHEC.Microbiological diagnosis, characterisation and clinical bacteriological aspects

   Author : Christina Welinder-Olsson; Göteborgs universitet; []
   Keywords : Escherichia coli; EHEC; VTEC; verocytotoxin; PFGE; EHEC-hemolysin; aerobactin; diarrhoea; HUS;

   Abstract : Enterohemorrhagic Escherichia coli (EHEC) constitutes a group of E. coli that in the past two decades has been the cause of several outbreaks of gastrointestinal disease. The microorganism causes hemorrhagic colitis (HC) and haemolytic uremic syndrome (HUS) in 5-10% of the patients, 30% of the HUS patients develop remaining kidney injuries. READ MORE

4. 2. Immunological characterisation of human anti-pig responses in vitro

   Author : Makiko Kumagai-Braesch; Karolinska Institutet; Karolinska Institutet; []
   Keywords : xenotransplantation-pig-islet cells-immune responses;

   Abstract : Xenotransplantation of organs or cells might solve the current problems of organ shortage. However, several problems need to be solved before xenotransplantation can become a successful clinical practice. Ethical, physiological, microbiological and immunological barriers need to be overcome. READ MORE

5. 3. Development and Application of ToF-SIMS for Clinical and Microbiological Analysis

   Author : Kelly Dimovska Nilsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; ToF-SIMS; Imaging mass spectrometry; Antibiotic resistance; Basal cell carcinoma; Gas cluster ion beam; GCIB; Time-of-flight secondary ion mass spectrometry; BCC; Escherichia coli; E. coli; FabF; DapF; Lpp; Lipid A; ECAcyc; Depth profile;

   Abstract : The aim of the work of this thesis was to further the implementation of timeof-flight secondary ion mass spectrometry (ToF-SIMS) in biological analysis and to generate new knowledge from the samples analysed. ToF-SIMS is a chemical analysis technique. READ MORE

6. 4. Surface characterisation of thermally modified spruce wood and influence of water vapour sorption

   Author : Susanna Källbom; Magnus Wålinder; Kristoffer Segerholm; Dennis Jones; Marko Petrič; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermally modified wood; Norway spruce; inverse gas chromatography IGC ; dynamic vapour sorption DVS ; X-ray photoelectron spectroscopy XPS ; surface energy; Värmebehandlat trä; gran; omvänd gaskromatografi IGC ; dynamic vapour sorption DVS ; röntgenelektronspektroskopi XPS ; ytegenskaper; ytenergi;

   Abstract : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. READ MORE

7. 5. Development of New Bacteria-Reducing Surfaces

   Author : Josefin Illergård; Monica Ek; Lars Wågberg; Eva Blolmberg; Ute Römling; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antibacterial; polyelectrolyte multilayers; polyvinylamine; Cellulose and paper engineering; Cellulosa- och pappersteknik;

   Abstract : In recent years, antibacterial surfaces have been a subject of increased interest. Especiallyinteresting are non-leaching, contact-active surfaces that physically disrupts the bacterialcell using immobilised cationic polymers. Thus the risks of bacterial resistance and discharge of hazardous biocides is minimised. READ MORE
