  1. 26. Strategies for the Discovery of Carbohydrate-Active Enzymes from Environmental Bacteria

    Författare :Johan Larsbrink; Vincent Bulone; Harry Brumer; Birte Svensson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CAZyme discovery; xyloglucan; polysaccharide-utilisation locus; microbiota; α-xylosidase; GH31; transglucosidase; human gut; SRA - Molekylär biovetenskap; SRA - Molecular Bioscience;

    Sammanfattning : The focus of this thesis is a comparative study of approaches in discovery of carbohydrate-active enzymes (CAZymes). CAZymes synthesise, bind to, and degrade all the multitude of carbohydrates found in nature. LÄS MER

  3. 27. Role of POU/Oct transcription factors in Drosophila immunity

    Författare :Widad Dantoft; Ylva Engström; Anne Uv; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antimicrobial peptides; Drosophila; host-pathogen interaction; immune gene expression; immune signaling; NF-kB; microbiota; POU Oct transcription factors; protein degradation; stress response; transcriptional regulation; Molecular Biology; molekylärbiologi;

    Sammanfattning : In response to infection, Drosophila melanogaster relies on the ability to mount a robust and potent innate immune response, characterized by induction of cellular and humoral processes. While rapid immune induction is of utmost importance, it is equally important to restrict and repress immune gene expression, where and when it is not needed. LÄS MER

  4. 28. Effects of FODMAPs and gluten on irritable bowel syndrome- from self-reported symptoms to molecular profiling

    Författare :Elise Nordin; Chalmers tekniska högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; short-chain fatty acids; metabotyping; Bristol Stool Form Scale; randomized clinical trial; double-blind; irritable bowel syndrome; FODMAPs; microbiota; personalized nutrition; fecal consistency; differential responses; metabolomics; stool water content; gluten;

    Sammanfattning : Irritable bowel syndrome (IBS) is a complex disorder of gut-brain interactions. The diagnosis of IBS is based on subjective reporting of abdominal pain and altered bowel habits in the absence of any clinical alterations of the gut or other pathological conditions. LÄS MER

  5. 29. Infections Related to the Use of Medical Devices and Changes in the Oropharyngeal Flora

    Författare :Hulda Thorarinsdottir; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; thrombosis; critical illness; biofilm; intratracheal intubation; ventilator-associated pneumonia; ; central venous catheters; catheter-related infections; proton pump inhibitors; oropharynx; MICROBIOTA; foreign-body reaction; hemolysis; inflammation;

    Sammanfattning : Background: Humans exist in mutualistic balance with a large range of microbiota. Illness and hospitalization can disturb this balance and contribute to hospital-acquired infections (HAIs), which occur most often in critically ill patients. LÄS MER

  7. 30. Effects of Dietary Fibre and Probiotics on Hindgut Fermentation in Healthy Rats and in Rats with Dextran Sulphate Sodium-Induced Colitis and Colon Cancer

    Författare :Camilla Bränning; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carboxylic acids; probiotics; short-chain fatty acids; hindgut fermentation; Colonic health; prebiotics; microbiota; dietary fibre;

    Sammanfattning : The importance of colonic fermentation has been realised during recent years as it has been found to be associated with colonic health and thus the overall health of the individual. The fermentation of dietary fibre and the addition of probiotics can have positive effects on the luminal environment and the colonic microbiota. LÄS MER
