Age pigment dynamics in worker-honeybees ( Apis Mellifera )
(Master thesis, 2013-08-27)Growing old is often related to a decline in physiological function, performance, survival or reproduction.(Kirkwood 2002) But studies among animals have showed that an increased chronological age doesn’t automatically ... -
Apoptosis is induced in bovine satellite muscle cells after removal of available oxygen
(Master thesis, 2013-08-28)Abstract Post-mortem tenderisation of meat is a complex process, of which all the details are far from understood. Cell death by apoptosis is recently proposed as a novel mechanism in this process. The main aim of this ... -
Biological vs. chemical regulation of nitrite concentrations in acidic and neutral pH soils : a study of kinetics and bacterial denitrifier communities
(Master thesis, 2015-11-06)Denitrification is an anaerobic microbial respiratory process, which takes part in the global biogeochem- ical nitrogen cycle. Microbial denitrifiers contribute to the global recirculation of nitrogen, by stepwise reduction ... -
Calorie and protein restriction in mammals : a review and comparison on respect to aging
(Master thesis, 2016-11-21)Calorie restriction (CR), a 10-50% (typically 30%) reduction in calorie intake with adequate nutrients, is the most widely accepted intervention to delay aging and increase lifespan in many model organisms. Recently, there ... -
Characterization of Escherichia coli AlkB homologue 1
(Master thesis, 2010-12-23)The DNA molecule is exposed to alkylating agents produced endogenously and in the environment. Cells have therefore developed several responses to alkylating damage including direct repair by oxidative demethylation. The ... -
Dendrittiske celler og Methylococcus capsulatus (Bath) - Interaksjon og funksjonelle effekter
(Master thesis, 2013-07-08)Forskningsgruppen ved laboratoriet for molekylær cellebiologi (IKBM) har vist at den ikkekommensale, metanotrofe bakterien M. capsulatus (Bath) binder til humane differensierte, monocyttderiverte umodne dendrittiske celler ... -
Establishment and characterization of a gatekeeper mutation for protein kinase D1 and 3
(Master thesis, 2016-09-07)Protein kinase D constitutes a novel family of Ser/Thr specific kinases and contains three members; PKD1-3. This protein kinase family has been described to carry out different functions and responses at various locations ... -
Evaluation of long-read Nanopore sequencing in genome studies
(Master thesis, 2017)The development of the latest generation of sequencing technologies, known as third-generation sequencing, has revolutionized sequence assembly due to long reads compared to the short reads of second-generation sequencing ... -
Expression and characterization of CBM33 proteins from Cellulomonas flavigena and Aspergillus terreus
(Master thesis, 2012-09-11)An essential element of a modern biorefinery is the enzymatic conversion of biomass to soluble sugars. Although the optimization of this process has been pursued by both academia and industry for decades, it still represents ... -
Genetic transformation of poinsettia (Euphórbia pulchérrima)
(Master thesis, 2015-11-05)Agrobacterium-mediated transformation and transformation by electrophoresis were used in an attempt to produce poinsettias (Euphórbia Pulchérrima) with blue or purple bracts. The two methods were compared in order to ... -
Human CaMKIIδ mutanter – proteinekspresjon, rensing, krystallisering og analyse av SN-peptid binding
(Master thesis, 2015-05-04)I denne oppgaven var målet å løse den 3-dimensjonale strukturen av komplekset mellom et peptid fra Sekretoneurin (SN) og Calmodulin (CaM) avhengig kinase IIδ (CaMKIIδ). Det ble derfor laget flere ulike mutanter av CaMKIIδ, ... -
In silico and in vitro studies of a non-commensal soil bacterium and its interactions with a mammalian host
(Master thesis, 2013-07-08)Methylococcus capsulatus (Bath) er en Gram-negativ, metanotrof bakterie. Til tross for at den aldri har vært beskrevet å være en del av tarmflora har M. capsulatus (Bath) vist seg å ha positive effekter ved inflammatoriske ... -
IncI1 resistance plasmids : studies on fitness cost, long-term stability, and shufflon rearrangements
(Master thesis, 2020)The plasmid-mediated spread of antibiotic resistance genes is considered a major dissemination pathway between related and non-related bacteria. IncI1 plasmids have been found to be carriers of a wide variety of bacterial ... -
Investigating novel biomarkers for neonatal asphyxia in newborn piglets
(Master thesis, 2015-07-31)Perinatal asphyxia is a condition in neonates with reduced oxygen (hypoxia) and/or reduced perfusion (ischemia). Today, we lack good biomarkers to measure the degree of oxidative damage caused by perinatal asphyxia. This ... -
Investigating The Role of FOXO1 in the Differentiation of Mesenchymal Stem Cells towards Chondrodytes
(Master thesis, 2012-10-15)Human mesenchymal stem cells (MSCs) have a profound potential in regenerative medicine. MSCs ability to differentiate into various tissue types in vitro provides a promising approach to tissue engineering and subsequently ... -
Karakterisering av antibiotikaresistens hos Escherichia coli isolert fra villrein i Norge
(Master thesis, 2015-08-06)Antibiotics revolutionized the medical industry when it was introduced due to its ability to cure infections that previously were difficult to treat. The increased use of antimicrobial agents has increased the selection ... -
Optimisation of nucleic acid extraction methods for a low pH soil, quantification of denitrification gene expression, and the analysis of gas kinetics from agricultural peat soils
(Master thesis, 2013-09-10)Denitrification is one of the main processes in the nitrogen cycle, and it is the reduction of nitrate to N2 through a series of intermediates, removing biologically available nitrate from the biosphere. NO and N2O are ... -
