  1. 1. Lactobacillus characterization and effects on oral biofilm composition

    Författare :Nelly Romani Vestman; Ingegerd Johansson; Jukka Meurman; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus; L. gasseri; probiotic traits; oral biofilm; breastfeeding; oral microbiota; odontologi; Odontology;

    Sammanfattning : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. LÄS MER

  2. 2. Microbiota of the alimentary tract of children - implications for allergy and inflammatory bowel disease

    Författare :Fei Sjöberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; gut flora; child; oral flora; allergy; duodenum; inflammatory bowel disease; culture; T-RFLP; pyrosequencing;

    Sammanfattning : Allergy, which is the most common chronic disease in Swedish children and adolescents, is associated with a high standard of living and Western lifestyle. According to the hygiene hypothesis, allergy is due to inadequate stimulation of the immune system by microbes during early childhood, leading to failed maturation of the immune system. LÄS MER

  3. 3. The immunomodulatory function of staphylococcal superantigen on oral tolerance

    Författare :Anna Stern; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICAL AND HEALTH SCIENCES; oral tolerance; superantigen; hygiene hypothesis; staphylococcal enterotoxin;

    Sammanfattning : Exposure to soluble proteins via the gut gives rise to systemic tolerance, a phenomenon called oral tolerance. Failure of oral tolerance results in allergy, a disease that has increased during the last decades in Western industrialized countries. The cause of this rapid increase is unknown. LÄS MER

  4. 4. Immunological tolerance to antigens in the intestine

    Författare :Malin Karlsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rat; oral tolerance; serum factor; normal gut flora; exosomes;

    Sammanfattning : The major part of the immune system is found in the epithelium and lamina propria of the gut. The distribution of the leukocytes is structured probably because the immune system has to distinguish between harmful microorganisms, food antigens and the normal gut flora. LÄS MER

  5. 5. Studies on oral health in mentally retarded adults

    Författare :Pia Gabre; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; caries; cooperation; deinstitutionalisation; Down syndrome; epidemiology; mental retardation; microbiology; periodontal disease; prevention; tooth mortality; prevention;

    Sammanfattning : During the last decades, a new policy involving normalisation, integration, equality and deinstitutionalisation of mentally retarded (MR) individuals has been accepted in Sweden. Consequently, many institutions have been closed and an increased number of people with MR are now integrated into the Swedish community. LÄS MER
