1. 6. Using metabolic profiles to screen for novel compounds in deep-sea sponges

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Författare :Samira Hilowle; [2022]
   Nyckelord :Metabolomics; Deep-sea sponges;

   Sammanfattning : The chemical diversity of the phylum Porifera have provided marine natural products (MNPs) such as alkaloids, terpenoids and peptides with ranging biological activity. Every two days a novel compound deriving from sponges are discovered. LÄS MER

3. 7. Översilningsytors potential att rena lakvatten från PFAS

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

   Författare :Emma Larsson; [2020]
   Nyckelord :PFAS; leachate; overland flow area; waste facility; waste; landfill; PFAS; lakvatten; översilningsytor; avfallsanläggning; avfall; deponi;

   Sammanfattning : Poly- and perfluorinated alkyl substances (PFASs) is a group of more than 5000 different substances, of which all consist of a fluorinated carbon chain resulting in a strong bond. Most of these substances are shown to be persistent, bioaccumulative and toxic for both humans and the environment. LÄS MER

4. 8. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers

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

   Författare :Pascal Camoiras González; [2019]
   Nyckelord :;

   Sammanfattning : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).

5. 9. Immunoassays or LC-MS/MS? : A Comparison Revealing the Properties of Modern Methods for Insulin, Pro-insulin, C-peptide and Glucagon Quantification

   Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Ruta Upite; Susanna Wärmegård; Casper Tiger; Anna Ivert Nordén; Temis Martinez; Viktor Umenius; [2019]
   Nyckelord :Biomarker quantification; insulin; pro-insulin; c-peptide; glucagons; immunoassays; LC-MS MS;

   Sammanfattning : The purpose of this report is to compare seven different methods for biomarker detection and quantification based on previously published papers. The methods investigated are ELISA, LC-MS/MS, UPLC-MS/MS, LC-IM/MS, IA-LC-MS/MS, MSIA-HR/AM, HTRF and AlphaLISA ® . LÄS MER

7. 10. Oligonucleotide analysis with 2D-LC-MS using mixed mode column

   Master-uppsats, Uppsala universitet/Analytisk farmaceutisk kemi

   Författare :Esther Goldberg; [2019]
   Nyckelord :mass spectrometry; 2D-LC-MS; mixed mode column; oligonuecleotide;

   Sammanfattning : In this project method development for analysis and characterization of an oligonucleotide sample containing two major impurities was done. For this purpose UPLC was used with a RP-WAX mixed mode column with UV and/or MS detection. LÄS MER
