The one-health approach in seaweed food production
(Peer reviewed; Journal article, 2022-01)Seaweeds are rich in macronutrients, micronutrients, and bioactive components and have great potential as sustainable resources in terms of both production and consumption of a desirable food. Still, the seaweed aquaculture ... -
Exploring Modified Alendronic Acid as a New Inhibitor for Calcium-Based Oilfield Scales
(Peer reviewed; Journal article, 2022-02)Organophosphorus compounds are well known as oilfield scale inhibitors. Earlier work showed that a series of new and well-known bone-targeting drugs incorporating non-toxic bisphosphonates (BPs) (PO3H2–C–PO3H2) gave good ... -
3D in vitro cancer models for drug screening: A study of glucose metabolism and drug response in 2D and 3D culture models
(PhD thesis UiS;, Doctoral thesis, 2022-03)Current drug screening protocols use in vitro cancer cell panels grown in 2D to evaluate drug response and select the most promising candidates for further in vivo testing. Most drug candidates fail at this stage, not ... -
Better prognostic markers for nonmuscle invasive papillary urothelial carcinomas
(PhD thesis UiS;, Doctoral thesis, 2022-04)Bladder cancer is a common type of cancer, especially among men in developed countries. Most cancers in the urinary bladder are papillary urothelial carcinomas. They are characterized by a high recurrence frequency (up to ... -
Monitoring farmed fish welfare by measurement of cortisol as a stress marker in fish feces by liquid chromatography coupled with tandem mass spectrometry
(Peer reviewed; Journal article, 2022-04)The aquaculture industry has become a sustainable source of food for humans. Remaining challenges include disease issues and ethical concerns for the discomfort and stress of farmed fish. There is a need for reliable ... -
Metabolic flux analysis of 3D spheroids reveals significant differences in glucose metabolism from matched 2D cultures of colorectal cancer and pancreatic ductal adenocarcinoma cell lines
(Peer reviewed; Journal article, 2022-05)Background Most in vitro cancer cell experiments have been performed using 2D models. However, 3D spheroid cultures are increasingly favored for being more representative of in vivo tumor conditions. To overcome the ... -
Low-temperature anaerobic wastewater treatment by granulated biomass
(PhD thesis UiS;, Doctoral thesis, 2022-05)In this study, long-term operation of up-flow anaerobic sludge blanket (UASB) system treating real municipal wastewater at decreasing temperatures (25, 16, 12, 8.5, 5.5, and 2.5 °C) and variable organic loading rates from ... -
Synthesis and Photodecomposition Studies of Photodegradable Antibiotics and Chitin Synthase Inhibitors
