Chicken antibodies, commonly referred to as IgY, have several properties that make them suitable for oral treatment of infections and there is essentially no risk for development of resistance. The overall aims of this thesis were to investigate Anti-Pseudomonas IgY as prophylaxis against infections with Pseudomonas aeruginosa for cystic fibrosis (CF) patients and to characterize the antibody treatment. We found that Anti-Pseudomonas IgY has affinity for P. aeruginosa flagellin, the major component of the flagellum. This is important since the flagellum is required for host invasion and establishment of infection. Flagellin induces inflammation. The main cause of morbidity and mortality among CF patients is chronic colonization of the airways with P. aeruginosa. We have studied prophylactic treatment of 17 Swedish CF patients with Anti-Pseudomonas IgY for up to twelve years. The results were compared with a control group of 23 Danish CF patients. Patients treated with IgY had 2.3 P. aeruginosa positive cultures/100 treatment months vs. 7.0 cultures/100 treatment months in the control group (p=0.028), and the time from inclusion to the first recolonization was significantly longer in the IgY-treated group (p=0.012). Lung function was preserved and patients treated with IgY had good nutritional status at the end of the study. Furthermore, other bacteria have not emerged instead of P. aeruginosa. Freeze-drying of IgY and the content of IgY preparations for oral use was investigated. Besides IgY, 26 egg yolk proteins were identified. Some of the proteins are known to have antimicrobial and immunostimulatory effects, and could have a positive additive effect to IgY treatment. Cholesterol levels were low. Conclusion: Anti-Pseudomonas IgY is a promising complement in the prevention of Pseudomonas aeruginosa infections in CF patients, partly explained by the fact that IgY binds to flagellin. / Felatkigt ISBN ändrat: Tidigare 978-91-554-7477-5 nu 978-91-554-7478-2

Fler unga människor än någonsin är idag överviktiga och stress och stressrelaterade symptom drabbar idag allt fler unga. Därför är det viktigt att unga människor får kunskaper om hur de på bästa sätt kan ta hand om sig själva.  Syftet med detta arbete är att undersöka hur elever som läser gymnasiets kurs Idrott och hälsa A ser på den hälsoundervisning de får. Detta är relevant för alla som arbetar som idrott och hälsa lärare för att kunna hitta en jämkning mellan kursplan och elevernas tankar och förkunskaper.  Genom intervjuer och fokusintervjuer kom jag fram till att eleverna vill lära sig mer om stress och hur man hanterar stress samt om kost. Eleverna tycker däremot att idrottsläraren inte är rätt person att lära ut kunskaper om tobak.

Awareness and study of the ways in which the environment can interact with the personal genetics and epigenetics of an individual has grown substantially in recent years, resulting in the field of Exposomics. In an era of increasingly personalized medicine, novel techniques are necessary to ensure the accurate and sensitivity measurement of clinically and environmentally relevant molecules in biological and environmental samples. Addressing existing shortcomings cited in literature, methods were developed and optimized for the extraction, separation, mass analysis, and quantification of a suite of environmental organic pollutants in both biological and environmental samples, with the primary objective of improving accuracy, increasing sensitivity, and reducing sample and reagent consumption. The secondary objective of this research was the production of validated methods capable of inter-laboratory method transfer with minimal training required in the receiving laboratory. Two novel methods have been developed, optimized, validated, and applied to collaborative environmental research. These novel methods represented a demonstrative improvement upon existing methods in both analytical quality and capability for inter-laboratory method transfer. Both developed methods were utilized in two collaborative clinical research studies investigating the impact of environmentally-sources agents on children diagnosed with autism spectrum disorders (ASD). The high-quality data obtained in these studies yielded results that may have provided valuable insight into the development and maintenance of autism spectrum disorders. These novel methods allowed for the discovery of a first-of-its-kind variable in the children with ASD, compared with controls. This variable was statistically predictive for the probability of an individual being diagnosed with the most behaviorally severe autism disorder, with a statistically significant overall model fit. This novel analytical method was then expanded in breadth through application to industrial and municipal wastewater to aid in updating EPA Method 625 for wastewater analysis. Applying this novel method to wastewater produced data of higher analytical quality, in both accuracy and precision, compared with all other collaborative laboratories. The methods developed in this work for the quantification of organic molecules implicated in environmental human health in biological and environmental samples have significantly improved analytically upon existing methods and have yielded clinically relevant findings in collaborative clinical research studies. / Bayer School of Natural and Environmental Sciences; / Chemistry and Biochemistry / PhD; / Dissertation;
