  1. 1. Impact of BPA, BPF and Mixture N1 on DNA-Methylation of GRIN2B and NR3C1 during human neuroprogenitor cell differentiation

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Fysiologi och miljötoxikologi

    Författare :Franziska Sophie Richter; [2023]
    Nyckelord :Epigenetics; Endocrine disrupting chemicals; DNA methylation; EDCs; Mixture effects; BPA; BPF; Mixture N1;

    Sammanfattning : Endocrine disrupting chemicals (EDCs) are ubiquitous and their adverse impact on nature, wildlife and humans is extensively researched. We are constantly exposed to EDCs, such as the widespread and extensively researched Bisphenol A, as well as its substitute Bisphenol F, which is coming into wider use, even though it is much less is researched and limited information is available about its endocrine effects.

  3. 2. Evaluation of critical instrument parameters for the transfer of LC-MS quantification methods between LC-MS/MS and Orbitrap MS

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Anna Stepanova; [2023]
    Nyckelord :;

    Sammanfattning : Transferring analytical methods is crucial in chemical laboratories. The need for the transfer may arise for different reasons such as sharing data between different laboratories, replacement or upgrade of analytical instrument, or limited instruments available etc. The performance and sensitivity of different instruments may vary.

  4. 3. Inledande utvärdering av epoxibaserad livstidsförlängning av fjärrvärmerör : Relining av kolstål med en polyamidhärdande lösningsmedelsfri epoxi

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Jennifer Andersson; [2022]
    Nyckelord :Relining; Epoxy; District heating; Corrosion; BPA; Glass-transition temperature; Relining; Rörinfodring; Fjärrvärmesystem; Livstidsförlängning; Korrosion; Rost; Epoxi; BPA; Tvärbundna polymerer; Sorption; Diffusion; Glasomvandlingstemperatur; Joniska transportvägar; Friktionsfaktor;

    Sammanfattning : Degradation of steel pipes in district heating systems is often a result of corrosion processes. To maintain the power in the systems the pipes gets replaced when they have been worn-out, resulting in high cost and long service time due to excavation. LÄS MER

  5. 4. Analysis of epigenetic changes induced by exposure to a mixture of endocrine disrupting chemicals in the mouse brain and a hippocampus mouse cell model

    Master-uppsats, Uppsala universitet/Miljötoxikologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Jennifer Ekholm Lodahl; [2021]
    Nyckelord :Epigenetics; Endocrine disrupting chemicals; DNA methylation; EDCs;

    Sammanfattning : Prenatal exposure to mixture N1, a chemical mixture consisting of four phthalate diesters,three pesticides and Bisphenol A, has been associated with behavioural changes as well as changes in gene expression in mice. In this study it was investigated whether the changes in gene expression could be explained by changes in DNA methylation. LÄS MER
