1. 1. Engineered nanomaterials in in vivo and in vitro models

   Författare :Laura Abariute; NanoLund: Centre for Nanoscience; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor nanowires; Nanoparticle exposure; Mouse exposure; Cell exposure; Nanotoxicology; Nanosafety; Fysicumarkivet A:2018:Abariute;

   Sammanfattning : Nanotechnology and engineered nanomaterials (ENM) empower existing technologies. One of the great examples are III-V semiconductor nanowires (NW), which have a broad application range. The occupational safety and hazard organizations draw attention to ENM, as their physical and chemical characteristics differ from the ones of bulk materials. LÄS MER

   Sammanfattning : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. LÄS MER

4. 3. Developmental Neurotoxicity of Environmental Pollutants : Effects on neuronal protein markers after neonatal exposure

   Författare :Iwa Lee; Henrik Viberg; Elena Jazin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental neurotoxicity; Neonatal exposure; Protein markers; Environmental pollutants; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Sammanfattning : This thesis focused on investigations of the developmental neurotoxic effects of bisphenol A (BPA) or perfluorohexane sulfonate (PFHxS), after a single neonatal exposure, during a critical period of the brain development in mice.BPA is a well-known industrial chemical used in the production of polymer products and PFHxS is used as an industrial additive as a surfactant.

7. 5. Low-Dose Ionizing Radiation Induces Neurotoxicity in the Neonate : Acute or fractionated doses and interaction with xenobiotics in mice

   Författare :Sonja Buratovic; Per Eriksson; Henrik Viberg; Bo Stenerlöw; Anders Fredriksson; Jean-René Jourdain; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionizing radiation; Neonatal; Neurotoxicity; Behaviour; Nicotine; Ketamine; Mouse; Cognition; Acute irradiation; Fractionated irradiation;

   Sammanfattning : This thesis examines the developmental neurotoxic effects of exposure to low-dose ionizing radiation (IR), alone or together with xenobiotics, during a critical period of neonatal brain development in mice.During mammalian brain development there is a period called the brain growth spurt (BGS), which involves extensive growth and maturation of the brain.
