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

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

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

    Abstract : 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.

  3. 2. Evolutionary Properties of Neural Networks: Exploration of Robustness and Evolvability in the Genotype-Phenotype Map

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Daesung Cho; [2022]
    Keywords : robustness; evolvability; genotype-phenotype map; canalization; Bayesian inference; simulation-based inference; information theory; neural networks; pyloric rhythm; Physics and Astronomy;

    Abstract : Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. READ MORE

  4. 3. Analysis of DNA methylation changes and behavioural outcomes in adulthood induced by prenatal exposure to a mixture of endocrine disrupting chemicals

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Shane Kamil; [2022]
    Keywords : Toxicology; Developmental biology; Epigenetics; Genetics; Methylation; EDC; Toxins; Chemicals; Mixture effect; Mediation; Toxikologi; Utvecklingsbiologi; Epigenetik; Genetik; Metylering; Miljögifter;

    Abstract : Endocrine disrupting chemicals, or EDCs, are some of the most prevalent toxic chemicals found in the environment because of human activity and they have a variety of adverse effects on both humans and wildlife. A proposed mechanism through which EDCs can negatively affect an organism is via an epigenetic mechanism known as DNA methylation, which can affect the development of the organism with negative outcomes later in life.

  5. 4. Investigation of the function of the SH3-like domain of the Saccharopolyspora erythraea iron-dependent regulator

    University essay from Uppsala universitet/Institutionen för kemi - BMC

    Author : Carita Hammar; [2022]
    Keywords : ;

    Abstract : The bacterium Saccharopolyspora erythraea is utilized to produce the widely used antibiotic erythromycin. With the increasing problem of antibiotic resistance, the development of derivatives of the drug is of great importance. To produce antibiotics biosynthetically, it is crucial to understand the metabolic pathways utilized by the bacterium. READ MORE

  6. 5. Binuclear zinc transcription factors and the regulation of patulin biosynthesis in the filamentous Ascomycete Penicillium expansum

    University essay from Lunds universitet/Bioteknik (master)

    Author : Robert Hansen Jagrelius; [2021]
    Keywords : secondary fungal metabolism; penicillium expansum; patulin; binuclear zinc transcription factors; dimerization; deepcoil; Biology and Life Sciences;

    Abstract : This thesis investigated the regulation of patulin production in Penicillium expansum in relation to fungal global regulators as well as the cluster-specific binuclear zinc transcription factor (BZTF) patL in silico. It also explored the state of BZTF research in filamentous ascomycetes fungi, and questioned if results in Saccharomyces cerevisiae can be freely translated to other taxonomic groups. READ MORE
