  1. 1. Regulation of bile acids by prebiotic food components : Studies in rat caecum and in serum of mice and humans

    University dissertation from Department of Food Technology, Lund University

    Author : Tannaz Ghaffarzadegan; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bile acids; Dietary fibre; Fat; Pectin; Guar gum; Barley; Lingonberry; Turmeric; Short-chain fatty acids; Gut microbiota; Caecum; Serum; Rat; Mice; Humans; GC-FID; UHPLC-MS;

    Abstract : Bile acids (BA) are formed from cholesterol in the liver and, apart from being part of fat digestion, they also act as signalling molecules in several health-related physiological processes. BA composition is regulated by gut microbiota as well as dietary fibre (DF) and fat in the diet. READ MORE

  2. 2. Structural Determination of Drug Metabolites from Doping Classed Compounds Using Mass Spectrometry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Annelie Hansson; Uppsala universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry; UHPLC-MS MS; doping control; Cunninghamella elegans; selective androgen receptor modulator; SARM; andarine; ostarine; LGD-4033; roxadustat; HIF stabilizer; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Abstract : Doping control in equine sports is important for a fair competition, but also to ensure the integrity of the betting system, as well as for animal welfare reasons. To detect the use of illicit compounds, screening for the parent compound is common. However, by using a metabolite as the analytical target instead, the detection time can be prolonged. READ MORE

  3. 3. Transformation of Micropollutants in the Hyporheic Zone

    University dissertation from Stockholm : Department of Environmental Science, Stockholm University

    Author : Malte Posselt; Jonathan P. Benskin; Michael Radke; Merle Plassmann; Magnus Breitholtz; Ian Cousins; Gudrun Massmann; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; micropollutants; hyporheic zone; biodegradation; bacteria; pharmaceuticals; transformation products; LC-MS MS; macrophytes; bedforms; suspect screening; mesocosm; flume; river; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Hyporheic zones (HZs) are reactive transition regions between rivers and aquifers which are thought to play an important role in the attenuation of micropollutants. Micropollutants are chemical substances such as pharmaceuticals, industrial chemicals or personal care products that are found in trace concentrations in the environment and that can be harmful to organisms.
