  1. 1. Structural studies of the surface adhesin SspB from Streptococcus gordonii

    Författare :Nina Forsgren; Karina Persson; Inger Andersson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; 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

  2. 2. Inflammatory cell death of human macrophages induced by Aggregatibacter actinomycetemcomitans leukotoxin

    Författare :Peyman Kelk; Anders Johansson; Charels A Dinarello; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aggregatibacter actinomycetemcomitans; leukotoxin; IL-1β; caspase-1; inflammatory cell death; pyroptosis; ODONTOLOGY; ODONTOLOGI; odontologi; Odontology;

    Sammanfattning : Aggregatibacter (Actinobacillus) actinomycetemcomitans is a bacterium mainly associated with aggressive forms of periodontitis. Among its virulence factors, a leukotoxin is suggested to play an important role in the pathogenicity. LÄS MER

  3. 3. On the relationship between spinal pain and temporomandibular disorders

    Författare :Birgitta Wiesinger; Anders Wänman; Per Sjölander; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; back pain; comorbidity; cross-sectional; dose-response; headaches; matched case-control; musculoskeletal disorders; prospective cohort; spinal pain; temporomandibular disorders TMD ; Other odontology; Övrig odontologi; odontologi; Odontology;

    Sammanfattning : Both spinal pain and temporomandibular disorders (TMD) commonly occur in the general population. Previous studies demonstrate neurophysiologic and biomechanical couplings between the trigeminal and cervical regions. LÄS MER

  4. 4. Oligodontia and ectodermal dysplasia : on signs, symptoms, genetics and outcomes of dental treatment

    Författare :Birgitta Bergendal; Christina Stecksén-Blicks; Margareta Molin Thorén; Göran Dahllöf; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tooth agenesis; oligodontia; ectodermal dysplasia; orofacial function; dental implants; EDARADD; Paedodontics; Pedodonti; odontologi; Odontology;

    Sammanfattning : The general aim of this thesis was to broaden our knowledge of the signs and symptoms, genetics, and outcomes of dental implant treatment in individuals with oligodontia or ectodermal dysplasia. Article I is a population-based study in three Swedish counties of 162 individuals with oligodontia, which was a prevalence of 0.09%. LÄS MER

  5. 5. Stability of bacterial DNA in relation to microbial detection in teeth

    Författare :Malin Brundin; Ulf Sjögren; Anders Johansson; David Figdor; Inge Fristad; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell-bound DNA; cell-death; dentine; DNA binding affinity; DNA decomposition; DNA preservation; extracellular DNA; hydroxyapatite; PCR; polymerase chain reaction; odontologi; Odontology;

    Sammanfattning : The fate of DNA from dead cells is an important issue when interpreting results from root canal infections analysed by the PCR technique. DNA from dead bacterial cells is known to be detectable long time after cell death and its stability is dependent on many different factors. LÄS MER
