Quantitative determination of ethyl glucuronide and ethyl sulfate in post-mortem blood using Hybrid-SPE-PPT and UHPLC–MS/MS
(Master thesis, 2015-12-03)Background: Alcohol misuse is associated with significant morbidity and mortality. Ethyl glucuronide (EtG) and Ethyl sulfate (EtS) are direct ethanol metabolites and powerful biomarkers for previous alcohol consumption. ... -
Quorum sensing circuits in Pseudomonas aeruginosa regulate N2O reduction
(Master thesis, 2016)Many bacteria respire in the absence of oxygen through reduction of nitrogen oxides (NOx) in the process called denitrification. Denitrification is the main greenhouse gas emitter by its release of N2O when high amounts ... -
Quorum sensing in the opportunistic pathogen Pseudomonas aeruginosa regulates N2O reduction
(Master thesis, 2019)Through a process called denitrification, bacteria can respire with the use of as terminal electron acceptors instead of oxygen. An intermediate of the denitrification process, nitrous oxide (N2O), often escapes to the ... -
Rapid and non-destructive analysis of intact potato tubers
(Master thesis, 2013-08-26)Abstract: The purpose of this study was to study and develop NIR spectroscopy for the prediction of dry matter content in intact unpeeled potato tubers. The techniques ability to measure dry matter content was also ... -
Rational engineering of a family 6 glycoside hydrolase
(Master thesis, 2017)Plant-based lignocellulosic biomass represents a significant global reserve of organic renewable energy, and is considered to have high potential to replace substantial portions of fossil-fuel dependency. Sugars derived ... -
Recognizing plasmid-reads by machine learning and K-mer statistics
(Master thesis, 2019)The aim of this project was to investigate to what extent some machine learning methods are able to classify chromosome reads from plasmid reads based on K-mer statistics. Both short Illumina HiSeq 2500 reads and medium-length ... -

Reduction of inflammation and increase in neurological repair mechanisms revealed by cerebrospinal fluid proteomics in multiple sclerosis patients after natalizumab treatment
(Master thesis, 2021)Multippel sklerose (MScl) er ein inflammatorisk sjukdom i sentralnervesystemet. I starten av sjukdomsløpet vil skaden på sentralnervesystemet bli reversert, men ettersom sjukdommen utviklar seg vil skadane bli meir alvorlege ... -
Reduksjon av forringelsesbakterier og ESBL-produserende Escherichia coli på kyllingfilet ved bruk av kontinuerlig UVC-lys og puls UV-lys
(Master thesis, 2015-08-06)Food safety and quality assurance of fresh poultry products involves several challenges in today’s poultry industry. Microbial requirements have created increased demands in the development of new methods for improved ... -
Regulation of denitrification in the genus Thauera; response pattern in the transition from oxic to anoxic environment, life on the energetic edge
(Master thesis, 2010-11-16)Denitrification is a taxonomically widespread process used by more than 60 different genera of bacteria including archaea and some fungi, where nitrate is reduced to dinitrogen gas (N2) by four enzymes; nitrate reductase ... -
Regulation of gelatinase production for Enterococcus faecalis in different growth media
(Master thesis, 2013-08-01)Enterococcus faecalis is a bacterial species colonizing the colon of most mammals. One of its most important virulence factors is gelatinase, which is an enzyme able to hydrolyze various peptides. Earlier research indicates ... -
The regulatory network underlying gene expression divergence of gene duplicates in Atlantic salmon
(Master thesis, 2021)Atlantic salmon, provides excellent opportunities for studying vertebrate genome evolution after whole genome duplication (WGD). This remains congruent with the extreme rate of duplicated gene copies following Ss4R (fourth ... -
Rensing og karakterisering av colwellicin, et antimikrobielt stoff isolert fra Shewanella colwelliana
(Master thesis, 2020)Da antibiotika ble introdusert på markedet, gav det håp om at infeksiøse sykdommer kunne bli bekjempet en gang for alle. Denne optimismen ble etter hvert overskygget av et økende antibiotikaresistensproblem. Resistensproblemet ... -
Repetitive regioner i Lactobacillus reuteri celle - og mucusbindende protein A (CmbA) - studier av variasjon og betydning for adhesjon til intestinale celler
(Master thesis, 2015-12-18)Hovedmål i dette arbeidet var å studere om den hypervariable repeterte regionen i den C-terminale delen av CmbA har betydning for adhesjon til intestinale epitelceller, og om forskjellige vekstfaser og mediekomponenter kan ... -
Resistance of serratia marcescens from food industry to quaternaty ammonium compounds
(Master thesis, 2013-09-10)In earlier days, antibiotic resistance was more concern than disinfectant resistance. During the last 20 years there has also been a focus on disinfectant resistance because of fear that wide spread used of disinfectant ... -
Review of potential entry and replication of human papillomaviruses in reproductive cells and possible correlations to health conditions
(Master thesis, 2019)Bakgrunn: Humant Papillomavirus (HPV) infiserer basale epitelceller i hud og slimhinner og i det siste er det fremmet hypotese om at HPV også kan smitte i ikke- epitelceller. Denne oversiktsstudien belyser omfanget av ... -
