Alginate hydrogels functionalized with β-cyclodextrin as a local paclitaxel delivery system
Omtvedt, Line Aanerud; Kristiansen, Kåre Andre; Strand, Wenche Iren; Aachmann, Finn Lillelund; Strand, Berit Løkensgard; Zaytseva-Zotova, Daria Sergeevna (Journal article, 2021)Modification of drug delivery materials with beta-cyclodextrins (β-CyD) is known to increase solubility of poorly water-soluble drugs, protect drugs from degradation and sustain release. In this study, we developed a ... -
Conspicuous parasite modifies appearance and energetics of a marine copepod
Eliassen, Lasse Krøger; Garvang, Even Sletteng; Andersen, Tom; Engseth, Erik; Kristiansen, Kåre Andre; Wiik-Nielsen, Jannicke; Titelman, Josefin (Journal article; Peer reviewed, 2024)Parasitism is an important driver of ecosystem processes. Copepods are fundamental trophic links in marine food webs and harbour many microeukaryotic parasites, but unreliable access to infected individuals limits quantitative ... -
