  1. 21. Mitochondrial efficiency : focus on dietary nitrate, hypoxia and exercise

    Författare :Tomas Schiffer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Metabolic efficiency affects weight control, generation of heat, exercise performance and health. The tiny radical nitric oxide (NO) targets several cellular components that can influence metabolic efficiency. NO is produced endogenously from L-arginine and molecular oxygen by specific NO-synthases. LÄS MER

  3. 22. Dentine caries : acid tolerant microorganisms and aspects on collagen degradation

    Författare :Anders Hedenbjörk Lager; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dental Caries; Collagen; Cariogenic Agents;

    Sammanfattning : Karies är en stor folksjukdom, trots att den både kan förebyggas och behandlas effektivt. Om man inte ingriper preventivt och låter det naturliga förloppet råda, kommer kariesangreppet till slut att bryta igenom emaljen och involvera även den underliggande dentinvävnaden. LÄS MER

  4. 23. Analytical approaches to the study of mucin glycosylation

    Författare :Kristina A Thomsson; Göteborgs universitet; []
    Nyckelord :mucins; O-linked glycosylation; mass spectrometry; cystic fibrosis; salivary mucins; sulfated oligosaccharides.;

    Sammanfattning : Mucins constitute the major protein component of the mucus layer, which covers the epithelial surfaces of the respiratory, the gastrointestinal and the genitourinary tracts. Mucins carry O-linked oligosaccharides which contribute to the molecule by 50-80 weight percent, and these can be highly diverse, with 50-150 different oligosaccharides found on a purified mucin population.

  5. 24. Toxicity and biocompatibility of nanoparticles, and studies on oxidative stress and DNA damage

    Författare :Ylva Rodhe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxidative stress is associated with several diseases, either as a cause or a consequence. Chronic kidney disease (CKD) is one example of a disease in which elevated levels of oxidative stress are frequently reported. LÄS MER
