  3. 2. Clinical, immunological and olfactory aspects of sinusitis and nasal polyposis : with special reference to patients with cystic fibrosis

    Författare :Gert Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nasal polyposis; sinusitis; cystic fibrosis; allergy; bacteria; in-patient; interleukin-8; muramidase; nasal lavage fluid; polymerase chain reaction; Pseudomonas aeruginosa; smell; olfaction; anosmia; hyposmia; olfactory threshold test; identification smell test; germ-free animal; T-cell receptor; normal microbiota.;

    Sammanfattning : The otorhinolaryngological approach to the problem concerning rhinosinusitis and nasal polyposis in the recessive genetic disorder of cystic fibrosis (CF) has been developed based on data from international studies. Opinions differ on how to treat the otolaryngological manifestations of CF (sinusitis, nasal polyps and hyposmia). LÄS MER

  4. 3. New micromanipulative techniques in reproductive biology

    Författare :José Inzunza; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : New micro manipulative techniques have facilitated development to help patients who suffer from infertility and spontaneous abortion, as well as those who carry severe genetic diseases and have risks of delivering an affected child. Preimplantation genetic diagnosis (PGD), which is based on obtaining blastomere biopsy from an eight-cell embryo, has made it possible to diagnose severe defects caused by a genetic factor. LÄS MER

  5. 4. The immunomodulatory function of staphylococcal superantigen on oral tolerance

    Författare :Anna Stern; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; 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

  7. 5. Characterization of toxicological effects of a novel in vivo benzo[a]pyrene metabolite in colonic cells

    Författare :Mirjam Nordling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Polycyclic aromatic hydrocarbons; benzo[a]pyrene; colon cancer; genotoxicity; oxidative DNA damage.;

    Sammanfattning : Cancer of the colon and rectum is the third most common cancer form in the world. Where the majority of cases fall into the category of sporadic colorectal cancer (CRC), lifestyle and diet have been found to be important risk factors associated with CRC. LÄS MER
