(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, 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 ...

(Master thesis / Masteroppgave, 2006)Environmental estrogens may modulate the endocrine system through interactions with sex steroid-binding protein (SBP), and these processes may be a novel mechanism for endocrine disruption. The endogenous hormone 17â-estradiol ...
-
(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, 2007)Iodinated x-ray contrast media (ICM) are used to improve the visibility of internal structures of the body in an x-ray image due to their ability to attenuate x-rays, providing enhanced contrast between regions of interest ...
-
(Master thesis / Masteroppgave, 2007)Persistent organic pollutants (POPs) have been widely distributed throughout the world for decades and while the use of some have been phased out, others are still being utilised and their levels are rising in biota. Levels ...
-
(Master thesis / Masteroppgave, 2007)NGFI-B (nerve growth factor-inducible clone B) is a nuclear receptor that has been implicated in both cell survival and cell death. In the nucleus, NGFI-B exerts its functions as a transcription factor that promotes survival ...
