PET is an effective tool for imaging of biochemical processes within patients and is instrumental for quantitative imaging of the availability of opioid receptors in the central nervous system. The opioid receptor system ...

The Hedgehog signaling pathway, first discovered in the fruit fly Drosophila melanogaster, was later found to be largely conserved in vertebrates and is crucial within diverse aspects of animal development, as well as for ...

Gjennom kunnskapsløftet av 2006 ble den grunnleggende ferdigheten Å kunne bruke digitale verktøy innført. Dette var et resultat av stadige teknologiske fremskritt, som også gjør det naturlig å innvie teknologien i ...

Det antidepressive legemidlet venlafaxin selges i dag som et racemat på tross av at dens to enantiomerer har ulik farmakologisk virkning. Asymmetriske synteser av venlafaxin finnes i litteraturen, men ingen av dem egner ...

Siden tusenårsskiftet har reaksjoner katalysert av ikke-metallholdige organiske molekyler (organokatalyse) økt i popularitet. Organokatalysatorer opererer under milde reaksjons betingelser og via flere aktiviseringsmoder. ...

I et prosjekt ved Institutt for Energiteknikk (IFE) skulle mekanismer studeres ved bruk av surfaktanter i kombinasjon med superkritisk CO2 for økt utvinning av restolje fra eldre oljereservoarer. Surfaktant sammen med CO2 ...

Målet med prosjektet var å få mer kunnskap og forståelse om de fysikalske og kjemiske egenskapene til én-dimensjonale kjeder av sinkoksid som en tilnærming til sinkoksidnanotråder. Hovedfokuset har vært å forstå de ...

Abstract c-Myb is a gene-specific transcription factor involved in the regulation of many target genes. As with other oncoproteins, an atypical function of the c-Myb may lead to uncontrolled cell growth and division that ...

The present thesis is focused on the methodology of lithiation-halogenation of 6-chloro-9-substituted purines and 9-substituted adenines via 8-purinyl anions. As an extension of this work, lithiation-halogenation of ...

In order to understand the single crystal X-ray structures of a series of synthetic peptides mimicking the Pro138-Gly144 segment of human AQP4 [1] , we have crystallized and determined the X-ray structures of some of these ...

A robust on-line automatic filtration and filter-flush solid phase extraction liquid chromatography tandem mass spectrometry (AFFL-SPE-LC- MS/MS) method for determination of 25hydroxycholesterol (25HC), 24S hydroxycholesterol ...

Correlations aimed at linking the hydration thermodynamics to materials parameters can be of vital importance for further development of proton conducting oxides. However, the currently proposed correlations are to a large ...

Double eigenvalues are not generic for matrices without any particular structure. A matrix depending linearly on a scalar parameter, Α + μΒ, will, however, generically have double eigenvalues for some values of the parameter ...

Passive air samplers (PAS) were deployed at 86 European background sites during summer 2006 in order (i) to gain further insight into spatial patterns of persistent organic pollutants (POPs) in European background air and, ...

This thesis shows that the indoor environment can significantly contribute to exposure to a type of environmental pollutants called perfluorinated compounds (PFC), although for most of us the highest intake comes from food, ...

The aim of this work was to investigate the potential of model materials designed by atomic layer deposition toward applications in catalysis research. Molybdenum based catalysts promoted with cobalt were selected as target ...

During the last decade, there has been an increased concern of impact to human health from exposure to lubricants and organophosphates (OPs) for workers in the aviation industry. In spite of this concern, neither methods ...

Background: Reproductive behaviors (such as age of childbearing, parity, and breastfeeding prevalence) have changed over the same historical time period as PCB emissions and may produce intergenerational differences in ...
