TAT-Modified Gold Nanoparticles Enhance the Antitumor Activity of PAD4 Inhibitors
(Journal article; Peer reviewed, 2020)Purpose: Histone citrullination by peptidylarginine deiminases 4 (PAD4) regulates the gene expression of tumor suppressor. In our previously study, YW3-56 (356) was developed as a potent PAD4 inhibitor for cancer therapy ... -
Technetium-99 (99Tc) in the North and Nordic Seas – the present status (2010) and a compilation of the Institute of Marine Research’s monitoring data (2003-2009)
(Master thesis, 2011-04-26)Technetium-99 (99Tc) is an anthropogenic, pure β-emitting (Emax = 292 keV) radionuclide with a half-life of 2.13 · 10^5 years. It is present in the marine environment primarily due to discharges from nuclear fuel reprocessing ... -
Tegn på forståelse av kjemi i elevrapporter: En undersøkelse av elevrapporter i programfag i kjemi
(Master thesis, 2018-06-26)Praktisk arbeid i realfagsundervisning er et tema som er mye diskutert i forskningen. Særlig problemstillinger som omhandler læringsutbyttet av praktisk arbeid er mye forsket på, og i den sammenheng også rapportene som ... -
Termokjemisk konvertering av fruktrester til plattformkjemikalier
(Master thesis, 2022-07-01)Furfural (FUR) og 5-hydroksymetylfurfural (HMF) kan dannes ved termokjemisk konvertering av pentose og heksose i fruktrester, samt andre biomasser. Både FUR og HMF anses som høyverdige plattformkjemikalier da de kan brukes ... -
The Heart as an Organ at Risk in Radiation Therapy of Locally Advanced Non Small Cell Lung Cancer
(Master thesis, 2023-06-02)Purpose: Currently, in radiation treatment planning for locally advanced non-small cell lung cancer (LA-NSCLC), the heart is typically contoured as a whole organ at risk. Both photon and proton beam techniques are used for ... -
