1. Vitamin A and Osteoporosis : Experimental and Clinical Studies
Sammanfattning : Vitamin A in high doses is severely toxic to the rat skeleton, and the active metabolite retinoic acid (RA) can induce bone resorption in vitro. An excessive dietary intake of vitamin A has been associated with reduced bone mineral density and an increased risk of hip fracture. LÄS MER
2. Determination of Fat-Soluble Vitamins in Foods Based on Supercritical Fluid Extraction
Sammanfattning : Sample clean-up methodologies based on supercritical fluid extraction (SFE) have been developed for determination of fat-soluble vitamins in foods. This thesis focuses on method development, stressing important issues concerning sample pre-treatment, extraction conditions and collection parameters. LÄS MER
3. Susceptibility to chronic liver disease
Sammanfattning : The onset and the progression of chronic liver disease involve environmental and genetic factors. Hepatic stellate cells (HSCs) are important players in these processes and are the main storage site for retinol. LÄS MER
4. Toxicity of brominated flame retardants with focus on retinoid system disturbances
Sammanfattning : Background: Brominated flame retardants (BFR) are detected in the environment and biota all over the world. They contribute to the human body burden of industrial chemicals and exposure is mainly via food. Indoor dust contributes substantially in some exposure situations, which involve small children.

5. Developmental exposure to mixtures of persistent environmental pllutants with focus on bone and retinoid system modulations
Sammanfattning : Environmental pollution of Arctic regions has evoked a scientific as well as public concern. Arctic Inuit inhabitants consume large amounts of fatty fish and marine mammals and are therefore exposed to levels of environmental toxicants that are suspected to cause adverse health effects.
