  1. 1. Ecological effects of pesticides in freshwater model ecosystems

    University dissertation from Lina Wendt-Rasch, Ecotoxicology, Ecologybuilding, Sölvegatan 37, Lund, Sweden

    Author : Lina Wendt-Rasch; Lund University.; Lunds universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; marine biology; aquatic ecology; limnology; Marinbiologi; Hydrobiology; community; zooplankton; algae; herbicide; insecticide; pesticide mixture; macrophytes; cypermethrin; metsulfuron-methyl; risk assessment; pesticides; microcosms; limnologi; akvatisk ekologi;

    Abstract : In this thesis I have investigated the effects of pesticide exposure on the ecosystem level using various types of experimental ecosystems, i.e. microcosms. The direct effect of exposure to cyperemthrin, a pyretroid insecticide, was a rapid decrease of crustancean zooplankton in enclosures in a lake. READ MORE

  2. 2. The Threat to the Baltic Salmon - a Combination of Persistent Pollutants, Parasite and Oxidative Stress

    University dissertation from Chemical Ecology and Ecotoxicology, Department of Biology, Lund University

    Author : Maria Persson; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Salmo salar; Atlantic salmon; polychlorinated biphenyls; Animal ecology; akvatisk ekologi; limnologi; Marinbiologi; limnology; aquatic ecology; marine biology; Hydrobiology; Ekologi; Ecology; lake Vänern; lake Vättern; Baltic Sea; Eubothrium crassum; aryl hydrocarbon receptor; AHR; consumption advice; stable isotopes; astaxanthin; EROD; M74; antioxidants; biomagnification; cestodes; parasites; DDT; Djurekologi; Environmental chemistry; Miljökemi; PCB;

    Abstract : Atlantic salmon (Salmo salar) from the Baltic Sea suffer from a reproduction disease known as the M74-syndrome. Newly hatched fry develop nerve disorders and die between 3-5 days after the first symptoms are seen. This is a maternally transmitted disease that is casued by a thiamine (vitamin B1) deficiency.

  3. 3. Photosynthetic Oxygen Evolution - EPR studies of the manganese cluster of photosystem II

    University dissertation from Sindra Peterson, Department of Biochemistry, Center for Chemistry and Chemical Engineering, Lund University

    Author : Sindra Peterson Årsköld; Lund University.; Lunds universitet.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; S2 state; second cycle; Biochemistry; Metabolism; Biokemi; metabolism; S0 state; light-adaptation; pulsed EPR; methanol; relaxation; microwave power saturation; S-cycle; Oxygen-evolving complex; Water-oxidizing complex;

    Abstract : In this thesis, a new electron paramagnetic resonance (EPR) signal from photosystem II is presented. The signal is shown to originate from the S0 oxidation state of the oxygen-evolving complex (OEC). READ MORE

  4. 4. Plant Membrane Proteomics - using isolated membranes and proteins to compare and quantify subproteomes

    University dissertation from Department of Biochemistry and Structural Biology, Lund University

    Author : Katja Bernfur; Lund University.; Lunds universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mass spectrometry; quantification; proteomics; metabolic labeling; plasma membrane;

    Abstract : Membrane proteins are particularly important to characterize, since they are involved in cellular processes of utmost importance in control and regulation of cells, such as transport across membranes, signal transduction and photosynthesis. The word "proteome" means all proteins expressed by a e.g. READ MORE

  5. 5. Development of Computational Methods for Cancer Research: Strategies for closing the feedback loop in omics workflows

    University dissertation from Department of Biochemistry and Structural Biology, Lund University

    Author : Ufuk Kirik; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; cancer; proteome profiling; bioinformatics; pathway analysis; mass spectrometry; Quantitative proteomics;

    Abstract : As the ultimate workhorses of the living things, proteins undergo significant regulatory activity throughout the lifetime of a cell or an organism. Many complex diseases effect the protein composition, expression or modification in the cells or tissues they arise in. READ MORE
