1. 1. Host ligands and oral bacterial adhesion : studies on phosphorylated polypeptides and gp-340 in saliva and milk

   Författare :Liza Danielsson Niemi; Ingegerd Johansson; Pernilla Lif Holgersson; Jukka Meurman; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adhesion; statherin; gp-340; caseins; human milk; saliva; Streptococcus mutans; Actinomyces; Cariology; Cariologi; kariologi; Cariology;

   Sammanfattning : Infectious diseases e.g. gastric ulcer, caries and perodontitis, are caused by bacteria in a biofilm. Adhesion of bacteria to host ligands e. LÄS MER

3. 2. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

   Författare :Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

   Sammanfattning : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. LÄS MER

4. 3. Structural studies of the surface adhesin SspB from Streptococcus gordonii

   Författare :Nina Forsgren; Karina Persson; Inger Andersson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Streptococcus gordonii; X-ray crystallography; surface adhesin; dental plaque; structural biology; Structural biology; Strukturbiologi; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

   Sammanfattning : Surface proteins on microorganisms that build up the oral biofilm are key players in the formation of the biofilm. Antigen I/II proteins are surface adhesins found on virtually all oral streptococci and share a conserved multi-domain architecture. These adhesins bind surface components on other bacteria and on host cells. LÄS MER

5. 4. Bacteria-agglutinating glycoproteins in human saliva : an in vitro study with special reference to Streptococcus mutans

   Författare :Jan Rundegren; Umeå universitet; []
   Nyckelord :agglutinin; glycoprotein; saliva; streptococcus mutans;

   Sammanfattning : The activity and specificity of salivary glycoproteins (agglutinins) aggregating various human indigenous microorganisms were studied in vitro. The agglutinin reacting with a serotype c strain of Streptococcus mutans was isolated and chemically characterized.The results can be summarized as follows:1. LÄS MER

7. 5. Mechanical and histological disturbances in advanced heart failure and cardiac transplantation

   Författare :Matteo Cameli; Michael Henein; Guy Lloyd; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Advanced heart failure; heart transplantation; speckle tracking echocardiography; left ventricular function; right ventricular function; left ventricular fibrosis; left ventricular filling pressure; atrial strain; kariologi; Cariology;

   Sammanfattning : The general purpose of this thesis is to establish capability and accuracy of speckle tracking echocardiography (STE) in assessing left atrial (LA), left ventricular (LV) and right ventricular (RV) function and their correlation with myocardial fibrosis, filling pressure and clinical outcomes in advanced heart failure (HF) patients before and after heart transplantation (HT).I demonstrated that HT recipients had impaired LV twist dynamics in the form of reduced rotation twist angle and untwist rate but time to peak twist was not different from the age matched controls and other cardiac surgical patients.
