(Master thesis / Masteroppgave, 2006)Abstract Perfluorinated alkylated substances (PFAS) are persistent compounds with many uses, for example impregnation of fabrics and leather and as fire-retardants. Recently, it has focused on these compounds, because of ...
-
(Master thesis / Masteroppgave, 2006)Fluorinated compounds (PFAS) and tributyltin (TBT) are found in significant amounts in the seas around the world and it is therefore of interest to know whether, and how, they affect coastal ecosystems. Three sediment-dwelling ...

Coelomocytter fra vanlig korstroll (Asterias rubens) som modell: bruk i testing av fremmedstoffer. (Master thesis / Masteroppgave, 2011)Utslipp av nye fremmedstoffer til det akvatiske miljø, som ulike legemidler og personlige pleieprodukter, er økende og er funnet i blant annet avløpsvann fra renseanlegg, kystvann, slam og biota. In vitro toksisitetstester ...

(Master thesis / Masteroppgave, 2006)Methyl mercury (MeHg), polychlorinated biphenyls (PCB) and some brominated flame retardants (BFR) are all neurotoxic compounds, known to exert their effects through their influence on neurotransmitter transport. Even though ...
-
(Master thesis / Masteroppgave, 2011)The purpose of this study was to investigate immunomodulating effects of environmental toxicants on cytokine and ROS production in white blood cells. Immunomodulating effects can either be investigated on a healthy immune ...
-
(Master thesis / Masteroppgave, 2012)Aquatic organisms are exposed to more or less continuous inputs of a wide range of potentially hazardous substances. The sources of the substances could be natural and/ or anthropogenic. This exposure may have deleterious ...
-
(Master thesis / Masteroppgave, 2010)The aim of the current study was to quantify DNA damage in red blood cells from natural populations of dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) in relation to chemical exposure in their natural habitat. ...
-
(Master thesis / Hovedoppgave, 2006)Cisplatin-based chemotherapy is known to be exceptionally effective in the treatment of testicular germ cell tumors. The molecular mechanisms underlying the sensitivity of testicular germ cell tumor cell lines to cisplatin ...
-
(Master thesis / Masteroppgave, 2009)Opiates have been used for centuries both as recreational drugs and for medical purposes. Opioids are substances that bind opioid receptors that are present throughout the nervous system. These receptors are the primary ...
-
(Master thesis / Masteroppgave, 2009)Numerous studies have explored the effects of morphine on cognitive function, while knowledge concerning methadone is scarce. This study is the first in line, being part of a newly started project. The aim of this study ...
-
(Master thesis / Masteroppgave, 2006)In the studies described in this manuscript, a new cellular model system has been developed and two fluorometric assays have been assessed for their applicability in biomonitoring and in vitro toxicity testing. Echinoderm ...
-
(Master thesis / Masteroppgave, 2011)Abstract Living organisms are usually exposed to combinations of a number of physical and chemical environmental factors in their natural habitats. Pre-exposure to sub lethal doses of a chemical may induce enhanced tolerance ...
-
(Master thesis / Masteroppgave, 2007)The release of persistent organic pollutants (POPs) into the environment for many decades has led to a worldwide contamination. The impact of pollutants on ecosystem and human health is an urgent and international issue ...
-
(Master thesis / Masteroppgave, 2009)Exposure to environmental toxicants is a contributing factor to health disorders such as cancer, asthma and allergy. A toxicant which has been studied more in depth the last years is the well known neurotoxicant acrylamide ...
-
(Master thesis / Masteroppgave, 2005)Cholinesterase (ChE) activity is a recognised biomarker of organophosphorus (OP) insecticide exposure. It is frequently applied to earthworms in the field of agriculturally linked ecotoxicology, because of the use of OP ...
-
(Master thesis / Masteroppgave, 2005)Norwegian: Ulike epidemiologiske studier har assosiert luftforurensning og dieseleksos med økt risiko for lungekreft. Dieseleksos inneholder en rekke ulike polysykliske aromatiske hydrokarboner (PAH) og nitrosubstituerte-PAH ...
