  1. 1. Does in vivo exposure to perfluorooctanesulfonicacid induce an altered colonic barrier function inmice?

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Hanna-Dalia Laar; [2022]
    Keywords : PFOA; PFAS; Ulcerative colitis; colon barrier; gastrointestinal permeability; Ussing Chamber;

    Abstract : Background: Several environmental risk factors have been implicated in the pathogenesis ofinflammatory bowel disease (IBD) and might cause an altered barrier function, a hallmark ofIBD. Recent evidence suggests that patients with late-onset ulcerative colitis (UC) have anincreased serum level of perfluoroalkyl substances (PFAS), one of the major chemical groupscontaminating our diet.

    Keywords : Liquid chromatography; Size exclusion chromatography; Agar; Chromatographic resins; Distribution coefficient; Vätskekromatografi; Storleksuteslutningskromatografi; Agar; Stationär fas; Fördelningskoefficient;

    Abstract : Vätskekromatografi är vanligt förekommande metod för separationer av molekyler inom bioteknik. Det finns inom begreppet vätskekromatografi många olika tekniker och vilken specifik teknik som är mest lämplig för en given separation beror på egenskaperna hos den avsedda målmolekylen. READ MORE

  4. 3. Modeling transport phenomena with COMSOL Multiphysics - Adsorptive membrane fouling in lignocellulosic biorefineries and lessons learned from it

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Linnéa Petersson; [2020]
    Keywords : QCM-D; Quartz crystal microbalance with dissipation monitoring; Hemicellulose; GGM; Galactoglucomannans; Adsorption; Membrane fouling; COMSOL; Chemical engineering; Kemiteknik; Technology and Engineering;

    Abstract : The separation of hemicelluloses, like glactoglucomannans, from lignocellulosic process streams is an important step in building profitable lignocellulosic biorefineries. The most common method for the separation is membrane filtration, however, it has the draw-back of being sensitive to membrane fouling. READ MORE
