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

    University essay from Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

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

    Abstract : 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. READ MORE

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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

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

    Abstract : 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. READ MORE

  4. 3. Toxicological analysis of Pyraclostrobin and Cyprodinilon Zebrafish larvae

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Kim Yeju; [2022]
    Keywords : gene expression; mixture effect; toxicity; pesticides; stress response;

    Abstract : Cyprodinil and pyraclostrobin are widely used pesticides to protect many plants from attack of microorganisms and fungal diseases. Although cyprodinil and pyraclostrobin exist in the aquatic environment at low concentration, their leftovers in the ecosystems lead to oxidative damage and interfere development in aquatic animals at environmental-relevant concentration.

  5. 4. Visualizing neuronal cell sub-populations using novel transgenic zebrafish lines.

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Aikaterini Zafeiriou; [2021]
    Keywords : Zebrafish; CRISPR Cas9; locomotion; confocal microscopy; immunohistochemistry;

    Abstract : Zebrafish is a frequently used model organism with an array of transgenic lines that have been used indevelopmental and physiological studies. We aim to generate novel transgenic zebrafish reporter lines to study subpopulations of spinal neurons in vivo. READ MORE

  6. 5. Assessment of zebrafish embryo toxicity of environmentally relevant antibiotics

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Ophelia Mastrangeli; [2021]
    Keywords : zebrafish embryo; toxicity; antibiotics; FET; Fish embryo toxicity; Bioaccumulation; zebrafiskembryo; toxicitet; antibiotika; FET; Bioackumulering;

    Abstract : Antibiotics are essential drugs in modern medicine. After consumption antibiotics are excreted in unmetabolized form in the urine and reach our sewage treatment plants (STP). STP are not able to degrade all antibiotics leading to release of antibiotics into the aquatic environment. Aquatic animals are thus continuously exposed to antibiotics. READ MORE
