  1. 1. Effect of elevated pCO2 and environmental oxazepam on the behavior and physiology of teleost fish

    Författare :Laura E. Vossen; Svante Winberg; Robert Gerlai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fish; GABA; CO2; ocean acidification; pharmaceutical pollution; oxazepam;

    Sammanfattning : This doctoral thesis investigated the effect of two aquatic pollutants on the behavior and physiology of teleost fish: i) elevated concentrations of carbon dioxide (CO2) in the context of ocean acidification and ii) low concentrations of the anxiolytic pharmaceutical oxazepam in the context of pharmaceutical pollution.Anthropogenic emissions of CO2 are lowering the pH of the oceans.

  3. 2. Fluoroquinolone resistance in the environment and the human gut – Analysis of bacterial DNA sequences to explore the underlying genetic mechanisms

    Författare :Anna Johnning; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antimicrobial resistance; Quinolones; Pollution; Next generation sequencing; Bioinformatics; Next generation sequencing;

    Sammanfattning : Fluoroquinolones (FQs) are synthetic, broad-spectrum antibiotics that target type II topoisomerases. High-level resistance is often caused by mutations in the target genes of FQs, especially in gyrA and parC. In contrast, plasmid-mediated resistance genes, such as qnr, often confer moderate levels of resistance. LÄS MER

  4. 3. Pharmaceutical and Biomedical Applications of Spectroscopy in the Photon Migration Regime

    Författare :Tomas Svensson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Porosimetry; Biomedical optics; Pharmaceutical analysis; Monte Carlo; Scattering media; Photon migration; Laser spectroscopy; High-resolution spectroscopy; Time-resolved spectroscopy; Time-of-flight;

    Sammanfattning : The present thesis is devoted to two different matters: One part is the development of a novel optical technique for characterisation of solid pharmaceutical materials. The other part being the continued development of photon time-of-flight spectroscopy, as well as exploration of new application areas of this method. LÄS MER

  5. 4. "Under pressure" : interaction between pharmaceuticals and river bacteria

    Författare :Aleksandra Hagberg; Madeleine Ramstedt; Mette Burmølle; Jerker Fick; Rikke Louise Meyer; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biofilms; river bacteria; pharmaceutical contamination;

    Sammanfattning : Pharmaceuticals are often entering the environment without being completely decomposed. Once released in the environment they continue to carry on their main function but instead targeting the inhabitants of the aquatic ecosystem. Our interest was drawn towards the bacteria, that are often present in the environment in the form of biofilms. LÄS MER

  7. 5. Effects of pharmaceuticals on natural microbial communities: Tolerance development, mixture toxicity and synergistic interactions

    Författare :Sara Brosché; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; antibiotics; pharmaceutical mixtures; microbial community ecotoxicology;

    Sammanfattning : Due to our extensive use of pharmaceuticals, low concentrations (picomol-nanomol/L) end up in the aquatic environment. Antibiotics comprise a group of pharmaceuticals specifically designed to disrupt microbial biochemical processes, and might therefore in particular have detrimental effects on microbial communities in the environment.
