  1. 1. Effects of early exposure to fluoxetine on behavioural development in zebrafish

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Moa Forssten; [2024]
    Nyckelord :Fluoxetine; zebrafish; development; behaviour;

    Sammanfattning : Many pharmaceuticals are stable molecules and after human excretion they enter the wastewater facilities where roughly 60 % is removed. The remaining residues will affect the concentration in close by streams and at the effluent, where fish like to spawn. Therefore, the development and behaviour of aquatic life is potentially at risk. LÄS MER

  3. 2. Acclimatisation of rats before scientific experiments

    Master-uppsats, SLU/Dept. of Clinical Sciences

    Författare :Viktoria Brånsgård; [2023]
    Nyckelord :acclimatisation; acclimatisation period; rat; transportation; stress; corticosterone;

    Sammanfattning : The most common laboratory animals in Sweden today are mice, rats, and zebrafish. We sent out an anonymous digital survey to investigate if scientific facilities in Sweden acclimatise their rats after transportation, how long the acclimatisation time is, and how the acclimatisation is conducted.

  4. 3. An Investigation of The Link Between Endocrine Disruption and Developmental Neurotoxicity Induced by Environmental Pollutants : In Zebrafish Embryos

    Master-uppsats, Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Maria Revenikioti; [2023]
    Nyckelord :Endocrine-disrupting chemical EDC ; Environmental pollutants; Endocrine disruption ED ; Developmental neurotoxicity DNT ; Development; Zebrafish embryos; Estradiol; DHT; BPF; PFOS.;

    Sammanfattning : Endocrine-disrupting chemicals (EDCs) are known to cause endocrine disruption (ED), developmental neurotoxicity (DNT), infertility and impaired embryo development. EDCs do therefore impose a threat to humans, wildlife and the environment. LÄS MER

  5. 4. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Monica Olsson; [2022-10-05]
    Nyckelord :Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Sammanfattning : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. LÄS MER

  7. 5. EFFECT OF ENDOCRINE DISRUPTING MIXTURES AND CHEMICALS ON THE OXYGEN CONSUMPTION RATE OF ZEBRAFISH LARVAE

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Lieke van Iersel; [2022-08-08]
    Nyckelord :oxygen consumption; zebrafish larvae; respirometry; endocrine disrupting chemicals; mixture toxicity;

    Sammanfattning : Chemicals affecting the endocrine system, so called endocrine disrupting chemicals (EDC’s), have been steadily increasing in the environment over the last 40 years. EDCs are harmful chemicals since they can act through multiple endocrine pathways, contain a wide spectrum of health effects that can be very persistent and can cause effects already at a low doses.
