16. Genes that modulate or mediate dopaminergic neurotransmission : expression of the human prodynorphin gene and association studies with candidate genes in an alcohol patient sample
Sammanfattning : The development of alcoholism may at least partly be attributed to the effect of ethanol on reward and reinforcement. As a genetic influence in the vulnerability to alcoholism and drug abuse has been documented, it is of interest to investigate genes active in brain structures which mediate reward and reinforcement.

17. Design of a rapid point-of-care immunoassay : Based on a single-step non-competitive immunoassay with magnetic permeability detection
Sammanfattning : This thesis describes the development of a one-step, specific, cost-effective and rapid in vitro point-of-care immunoassay test based on a unique magnetic immunoassay principle. The principle in question is based on a non-competitive heterogeneous immunoassay in a one-step analysis, relying on magnetic permeability detection. LÄS MER
18. An electrostatic sampling device for point-of-care detection of bioaerosols
Sammanfattning : Bioaerosols are not only a significant factor of air quality but contribute greatly to the spread of infectious diseases, specifically through expired pathogen-laden aerosols. Clear examples of airborne transmission include: the recent influenza pandemic of 2009, the ongoing tuberculosis epidemic, and yearly norovirus out- breaks, which affect millions of people worldwide and pose serious threats to public healthcare systems.

19. Estimating and reducing errors in soil sampling
Sammanfattning : Contaminated sites are sampled and analysed to assess their remediation need. In the process the question arises if the results of the analysis represents the site they are taken from properly. Sampling and preparation is known to induce errors. Results from the analysis of soil samples may be expected to include errors. LÄS MER
20. RNA systems for NMR studies in vitro and in vivo
Sammanfattning : NMR spectroscopy is an excellent tool to study the structure-function relationship of RNA. Such measurements are usually performed in vitro, which requires large amounts of isotope- labeled sample in high purity and can give access to individual atoms, structure of the molecule and conformational dynamics.
