Cloning, characterization and expression of three B22R genes from Salmon Gill Poxvirus
(Master thesis, 2020)Salmon Gill Poxvirus Disease (SGPVD) is a severe viral disease that can cause acute mortality in farmed Atlantic salmon. The disease is caused by SGPV that is a large DNA virus. The virus infects gill epithelial cells and ... -
Protein dysregulation in immune cells of multiple sclerosis patients
(Master thesis, 2020)Multiple sclerosis (MS) is a complex, autoimmune and inflammatory disease affecting the central nervous system. The pathogenesis of MS is not completely understood, but T cell activation is believed to be an important part ... -
Identifisering av betalaktamaser med utvidet spektrum (ESBL og karbapenemaser) i bakterieisolater fra vannmiljøer ved bruk av fenotypiske og genotypiske metoder
(Master thesis, 2020)Antibiotikaresistens (AR) er en av de største truslene mot global helse i dag. Utviklingen av betalaktamaser med utvidet spektrum (ESBL) i Enterobacteriaceae vekker spesielt stor bekymring, da betalaktamer er den mest ... -
Purification and characterisation of new bacteriocins
(Master thesis, 2020)Not long after the discovery of the first antibiotics in the 20th century, bacteria resistant to this treatment has appeared and the spread of their genes can occur in several ways. This development has just increased, and ... -
The microbial diversity of mesophilic starter cultures used in cheese production
(PhD Thesis;2017:96;, Doctoral thesis, 2017-11)For ages, humankind has preserved various foods by fermentation by lactic acid bacteria (LAB), and fermentation of milk to obtain cheese can be traced back to the domestication of cattle, at least seven millennia ago. ... -
Kva innsikt kan biometriske målingar gje om studentar si oppleving av statistikkundervisning?
(Master thesis, 2020)I dette prosjektet har ein freista å avdekkje samanhengar mellom personlegdomstypar og opplevinga av to undervisningsfilmar om same tema, men med forskjelleg innhald og oppbygning. Alle deltakarane fekk sjå begge filmane ... -
Investigating evolution of gene regulation with crossspecies comparative transcriptomics
(PhD Thesis;2017:101, Doctoral thesis, 2017)An essential ability of all lifeforms is to regulate the activity of its genes. This ability is what allows multicellular organisms to generate hundreds of completely different cells despite having the same genome. It is ... -
Potensialet for redusert plastforbruk til emballering av kyllingfilet ved bruk av monomaterialer (APET og HDPE) for å øke resirkuleringsgraden
(Master thesis, 2020)I dag er det vanlig å pakke kyllingfilet i det komplekse materialet amorf polyetylentereftalat/polyetylen (APET/PE) som ikke er resirkulerbart. Det er behov for å se på muligheten for å bytte til monomaterialer som er ... -
Syntetisk studier av fenolisk difenylmetan derivater for bruk som modellforbindelser av lignin
(Master thesis, 2020)Kondensasjonsreaksjon av lignin fragmenter er et av problemer for effektiv utnyttelse av lignin. Denne typen reaksjonen ble tidligere studert av Shimada et al[1] der enkelt difenylmetan analog var syntetisert fra blant ... -
Developing and validating tests for a metabolic model of Atlantic salmon (Salmo salar)
(Master thesis, 2020)The fish farming industry is expanding, and to achieve economic and ecological sustainability, new fish feeds are being developed. When developing new feeds, it can be useful to first simulate on a computer how the biological ... -
Identification of RseP as a receptor for hybrid bacteriocin H1 in emerging pathogen Staphylococcus haemolyticus
(Master thesis, 2020)Staphylococcus haemolyticus is an emerging pathogen which may transfer multi-drug resistance genes to highly virulent Staphylococcus species. S. haemolyticus is a biofilm-producing bacterium and one of the most frequent ... -
Novel aspects of the ecophysiology of denitrifying bacteria and their roles in N2O emissions
(PhD Thesis;2017:91, Doctoral thesis, 2017)Environmental bacteria are in general limited by nutrient availability, and as the conditions fluctuate rapidly and unpredictably they must adapt or they will not thrive. This requires fast and adequate sensing and ... -
Synthesis of some marine natural product fatty acid derivatives
(PhD Thesis;2016:74, Doctoral thesis, 2020-11-24)The research presented in this thesis puts forth total syntheses of two marine natural products: (-)-mucosin and (+)-crucigasterin 277. Both syntheses focus on producing enantiopure natural products derived from commercially ... -
Parameters and pedigrees in forensic genetics and statistics
(PhD Thesis;2017:46, Doctoral thesis, 2017)With the rapidly evolving DNA technology today, there is a constant need of more robust statistical methods for analyzing the data. The sequencing techniques are improving, making more genetic markers available, and we are ... -
An examination of stress resistance and lifespan extension in the honey bee, Apis mellifera
(PhD Thesis;2013:48, Doctoral thesis, 2013)Many societies and health systems will soon face the unprecedented challenge of burgeoning aged populations. This demographic change will place pressure on social and medical systems, and give rise to questions concerning ... -
Discovery and characterization of enzymes acting on chitin
(PhD Thesis;2017:71, Doctoral thesis, 2017)In the shift from a fossil-based to a bio-based economy, exploration of renewable recourses is needed. Chitin is considered the second most abundant polysaccharide on Earth, after cellulose, and its water-soluble derivatives ... -
Mitochondrial oxygen consumption and myoglobin redox stability in beef
(PhD Thesis;2012:14, Doctoral thesis, 2012)Myoglobin is the main pigment in meat and exists in three predominant states; deoxymyoglobin (DMb), oxymyoglobin (OMb), and metmyoglobin (MMb). The different myoglobin states are dependent on the production of mitochondrial ... -
