Synthesis of substituted imidazoles that stabilizes Survival Motor Neuron Protein for treatment of Spinal Muscular Atrophy
(Master thesis, 2019-08-31)Spinal muscular atrophy (SMA) is a common autosomal recessive disorder and the leading cause of infant mortality. Patients with this disorder are missing the SMN1 gene that is producing 80-90 % of the Spinal motor neuron ... -
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 ... -
A Theoretical Study of Cr/oxide Catalysts for Dehydrogenation of Short Alkanes
(Doctoral thesis, 2006-10-27)Natural gas reserves are being produced at increasing rates world wide, thus providing an abundance of short-alkane feedstock for the petrochemical industry. Effective routes to selective activation of short alkanes may ... -
