1. 1. Synthesis of Fluorescent Analogues of FluoBar1 for Studying Protein Expression Rates in Living Cells

   Master-uppsats, Uppsala universitet/Organisk kemi

   Författare :Victor Hellgren; [2022]
   Nyckelord :;

   Sammanfattning : L-type voltage gated calcium channels are membrane bound ion channels that regulate the intracellular concentration of calcium ions as a response to changes in the membrane potential. They exist in four isoforms and recent studies have brought extra attention to the Cav1. LÄS MER

3. 2. Development and Validation of an UPLC-MSMS Method for the Analysis of Patulin in Apple-based Food Products

   Master-uppsats, Uppsala universitet/Analytisk kemi

   Författare :Tobias Hjortsberg; [2022]
   Nyckelord :Patulin; UPLC; LC-MS MS; apple; development; validation; mycotoxins; ESI;

   Sammanfattning : This project focused on the development and validation of an ultra-performance liquid chromatography tandem mass spectrometer (UPLC-MS/MS) method for the determination of Patulin in apple-based products. Patulin is one of the many mycotoxins that are secondary metabolites from about 60 filamentous fungi. LÄS MER

4. 3. Occurrence of organic micropollutants and hormones in Swedish surface water

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Malin Forsberg; [2022]
   Nyckelord :surface water; wastewater; SPE; pharmaceuticals; target analysis; ytvatten; avloppsvatten; SPE; läkemedel; målanalys;

   Sammanfattning : The occurrence and source distribution of organic micropollutants (OMPs) have been investigated in Swedish surface waters, in 23 rivers connected to the lakes Vänern, Vättern and Mälaren, 3 Wastewater treatment plants (WWTPs) and 3 Drinking water plants (DWTPs) located in the middle of Sweden was sampled. Compounds such as pharmaceuticals, industrial chemicals, pesticides, personal care products, hormones, Per- and polyflouroalkyl substances (PFASs), isoflavones, stimulants and parabens were selected.

5. 4. Evaluation of Pre-Analytical Processes on Lipemic Whole Blood Samples Used in Forensic Toxicology

   M1-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

   Författare :Emily Elenstål; [2022]
   Nyckelord :lipemia; post-mortal; whole blood; benzodiazepines; Intralipid; liquid-liquid extraction; solid-phase extraction;

   Sammanfattning : Introduction: Post-mortem whole blood samples differ greatly in quality, lipemia is one cause of concern in toxicological analyses. Around 4 % of all samples sent to RMV are given a notation of lipemic content. LÄS MER

7. 5. Monitoring illicit drugs of abuse in wastewater from Umeå, Örebro, Örebro University and Örebro University Hospital

   Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

   Författare :Tove Slettvoll; [2022]
   Nyckelord :;

   Sammanfattning : Illicit drugs constitute a class of contaminants whose emissions to the environment has drawn attention due their potent pharmacological and biological activities. The monitoring of illicit drugs in wastewater and surface waters provides a powerful tool to investigate the presence, trends and to estimate the consumption of these psychoactive substances at the community level.
