Aerobic fitness and metabolic health in children: A clinical validation of directly measured maximal oxygen consumption versus performance measures as markers of health
(Peer reviewed; Journal article, 2017-09)High aerobic fitness is consistently associated with a favorable metabolic health profile in children. However, measurement of oxygen uptake, regarded as the gold standard for evaluating aerobic fitness, is often not ... -
ALADDIN: Docking Approach Augmented by Machine Learning for Protein Structure Selection Yields Superior Virtual Screening Performance
(Peer reviewed; Journal article, 2019-10)Protein flexibility and solvation pose major challenges to docking algorithms and scoring functions. One established strategy for addressing these challenges is to use multiple protein conformations for docking (all‐against‐all ... -
Aldol condensations on a 3-alkylidene-2,5-diketopiperazine - synthesis of two marine natural products
(Peer reviewed; Journal article, 2018)The synthesis of two marine natural products containing a 3-alkylidene-6-arylidene-2,5-diketopiperazine scaffold by employing two consecutive aldol condensations starting with 1,4-diacetyl-2,5-diketopiperazine is reported. ... -
Alkyl-phenanthrenes in early life stage fish: differential toxicity in Atlantic haddock (Melanogrammus aeglefinus) embryos
(Journal article; Peer reviewed, 2023)Tricyclic polycyclic aromatic hydrocarbons (PAHs) are believed to be the primary toxic components of crude oil. Such compounds including phenanthrene are known to have direct effects on cardiac tissue, which lead to ... -
Alkylation of TEB Acetylide Using Tosylates
(Master thesis, 2018-12-19)Alkylated products of 3,3,4,4-tetraethoxybut-1-yne (TEB) where prepared from alkylation of the TEB acetylide with a selection of alkyl tosylates, obtained by tosylation of the corresponding tosylates, and alkyl iodides in ... -
Alkylfenolers innvirkning på glyserofosfolipidmembraner og kolesterol i torskehjerne
(Master thesis, 2003)Oljeindustrien slipper ut store mengder produsert vann, som inneholder flere potensielle giftstoffer, blant annet alkylfenoler. Det ble tidlig vist at alkylfenoler kan ha skadelig virkning, særlig på grunn av østrogenhermende ... -
Amino-Functionalised Pillared-Layered Metal-Organic Frameworks: Characterisation and Selective Adsorption Properties
(Master thesis, 2021-06-01)Materials technology, with the focus of discovery of new materials which are tailor-designed with a very particular set of properties suitable for application, has provided essential developments for the modern society ... -
Analyse av antocyaner i bjørnebær (Rubus fruticosus)
(Master thesis, 2010)Tema for denne oppgaven er analyse av antocyaner i bjørnebær. Antocyaner er naturlige pigmenter som gir opphav til farger varierende fra oransje og rød til fiolette og blå i blomster, frukt og andre planter (Melo et al. ... -
Analyse av forbindelser av høymolekylær vekt i pollen ved bruk av termokjemolyse-GC-MS og FT-IR
(Master thesis, 2016-11-21)Organisk materiale inneholder komplekse polymerer med høy molekylvekt og stor kjemisk stabilitet, som det er vanskelig å analysere med tradisjonelle metoder. Termokjemolyse er en teknikk som kan omdanne de komplekse ... -
