    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biomarker; DDT; environmental monitoring; EROD; fish; GSI; nanoinjection; PAH; PCB; Perca fluviatilis; perch; reproduction; Environmental toxicology; Miljötoxikologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : This thesis reports the results of biomarker measurements in three environmental monitoring projects. In the first project, which was part of the Swedish national environmental monitoring, biomarkers were measured annually in female perch (Perca fluviatilis) in two background areas in the Baltic Sea during 1988–2000, resulting in a unique 13-year series of measurements.

    Sammanfattning : The first part of this thesis is about the development of a method to inject various substances into the yolk of fish eggs. The method was named nanoinjection and enabled the injection of volumes as small as 10-9 L into the yolk of single fish eggs directly after fertilization, with insignificant mortality due to the injection.

    Sammanfattning : Neurodevelopment is a highly dynamic process involving hundreds of molecular different cell types. Gain and loss of function studies provide valuable insight into the gene regulatory networks that orchestrate this morphological process. LÄS MER

  4. 4. Lineage tracing of early organogenesis and liver mesenchymal cells with ultrasound-guided in utero nano-injection

    Sammanfattning : Current methods used to investigate embryo development and alter gene expression in mouse embryos are often time consuming and require large numbers of mice. To circumvent these limitations, we were aiming to develop a flexible and efficient method to investigate embryo development and manipulate gene expression in utero. LÄS MER
