Analysis of Fatty Acids by High Performance Liquid Chromatography and Electrospray Ionization-Mass Spectrometry
(Master thesis, 2019-09-28)Fatty acids (FA) have been traditionally analyzed by gas chromatography (GC) as fatty acids methyl esters (FAME) and more recently using mass spectrometry (MS) detection. Since high performance liquid chromatography (HPLC) ... -
Analysis of Polymer Injectivity in Porous Media
(Doctoral thesis, 2021-07-01)Polymers are chemical substances that occur both naturally or synthesized and consist of large macromolecules. They are created by the process of polymerization of many smaller molecules also known as monomers. Due to their ... -
Analysis of polyphenolic content in marine and aquatic angiosperms from Norwegian coastal waters
(Doctoral thesis, 2018-04-26)In this work, the polyphenolic content in extracts of Zostera marina L., Zostera noltii Hornemann, Ruppia cirrhosa (Petagna) Grande and Ruppia maritima L. from Norwegian coastal waters was characterized for the first time. ... -
Analysis of Polyphenols from Laminaria hyperborea for application as Life Science ingredients
(Doctoral thesis, 2023-09-01)Makroalger, også kjent som tang og tare, er anerkjent som en verdifull kilde til bioaktive forbindelser. Av disse har polyfenoler fått særlig oppmerksomhet. Polyfenoler har blitt assosiert med en rekke helsefordeler, og ... -
Analysis of the flavonoids and phenolics found in the marine angiosperm Plantago maritima collected in Norway
(Master thesis, 2023-05-11)This master project has a focus on extraction, separation and identification of flavonoids and other phenolic compounds in Plantago maritima. Previously in Norway there has only been done one small pilot study (bachelor ... -
Analysis of the FLVR motif of SHIP1 and its importance for the protein stability of SH2 containing signaling proteins
(Peer reviewed; Journal article, 2019)Binding of proteins with SH2 domains to tyrosine-phosphorylated signaling proteins is a key mechanism for transmission of biological signals within the cell. Characterization of dysregulated proteins in cell signaling ... -
Analysis of the marine sponge Pachymatisma normani
(Master thesis, 2020-06-12)Marine sponges are evolutionary some of the oldest multicellular organisms on earth and have in the last few decades attracted an increasing amount of attention. Sponges are simple filter feeders that host symbiotic ... -
Analytisk karakterisering av asfaltener felt ut ved forskjellige betingelsar frå Athabasca bitumen
(Master thesis, 2014-05-30)Bitumen inneheld organiske sambindingar kor nokre har polare strukturelle trekk som varierar i oppbygnad, eigenskapar og molekylmasse. Dei største og mest polare av desse sambindingane blir under ein samlebetegnelse kalla ... -
Anthocyanin Profile and Antioxidant Activity of Edible Leaves of Dissotis brazzae Cogn (Melastomataceae)
(Journal article, 2020)Anthocyanins are colored bioactive phytochemicals in the class of flavonoids with high potential as dietary antioxidants. Demand for anthocyanins in functional food and nutraceutical industries has continued to increase ... -
Anthocyanin Profile and Antioxidant Property of Anti-asthma Flowers of Cordyline terminalis (L.) Kunth (Agavaceae)
(Journal article; Peer reviewed, 2020)Cordyline terminalis flower is traditionally used to treat asthma and the purple color of the flower is suggestive of anthocyanins. The purpose of this study was to characterize and determine the antioxidant property of ... -
Antibacterial and Anticancer Drugs - Interaction with DNA
(Doctoral thesis, 2006-06-09)This thesis is concerned with the interactions of drugs with DNA mediated by metal ions. The interactions of two types of drugs were investigated: fluoroquinolone antibacterial agents, represented by ciprofloxacin (cipro), ... -
Application of Antisolvent Precipitation Method for Formulating Excipient-Free Nanoparticles of Psychotropic Drugs
(Journal article; Peer reviewed, 2022)The aim of the present study was to systematically examine the effects of variations in the process parameters of the antisolvent precipitation method employed in the preparation of excipient-free pure nanoparticles of ... -
Application of liquid chromatographymass spectrometry and chemometrics in the automated characterization of molecular lipid species
(Doctoral thesis, 2015-11-05)Lipidomics is an important field that has attracted extensive interest worldwide, due to the increasing awareness of crucial lipid functions in biological systems. Lipidomics aims at detecting, characterizing and quantifying ... -
An approach to assess and adjust for the influence of multicollinear covariates on metabolomics association patterns-applied to a study of the associations between a comprehensive lipoprotein profile and the homeostatic model assessment of insulin resistance
(Journal article; Peer reviewed, 2022)Introduction Comprehensive lipoprotein profiling using proton nuclear magnetic resonance (NMR) spectroscopy of serum represents an alternative to the homeostatic model assessment of insulin resistance (HOMA-IR). Both ... -
