16. Development of UPLC-MS/MS method for the determination of polar metabolites
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Trimethylamine-n-oxide (TMAO) is a metabolite found in plasma/serum in humans. Elevated levels of TMAO have been associated with several types of heart disease. It’s therefore of interest to make a simple analytical method to analyse TMAO and other metabolites that are degraded to TMAO, including betaine. LÄS MER
17. Ethanol, ethyl glucuronide, and ethyl sulfate kinetics after multiple ethanol intakes : A study of ethanol consumption to better determine the latest intake of alcoholin hip flask defence cases
M1-uppsats, Linköpings universitet/KemiSammanfattning : The hip-flask defence is a common claim in drunkdrinking cases. In Sweden and Norway two different models are used to determinethese cases. In Sweden one blood and two urine samples taken 60 minutes apartare used for analysis. In Norway two blood samples taken 30 minutes apart areused. LÄS MER
18. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.

19. Biotillgänglighet av atropin vid topikal ögonbehandling hos häst och metoder för objektiv mätning av tarmmotilitet
Master-uppsats, SLU/Dept. of Clinical SciencesSammanfattning : Atropin är ett vanligt förekommande läkemedel vid behandling av uveit hos häst för att inducera mydriasis och relaxera ciliarmuskulatur och irissfinkter, i syfte att ge smärtlindring samt minska risken för kroniska komplikationer. Tidigare studier har visat att intravenös samt topikal administrering av atropin kan ge upphov till minskad tarmmotilitet och risk för att utveckla kolik (Ström et al. LÄS MER
20. Long-range Transport of Per- and Polyfluorinated Substances to Sweden : The Exposure in Mountain Grazing Reindeers
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The aim of this study was to examine if perfluorinated alkylated substances (PFASs) reaches north of Sweden by long-range atmospheric transport. This was done by monitoring the levels of PFASs in reindeer livers at two locations in 2002 and 2010, respectively. LÄS MER
