Effects of protein enrichment in texture modified and minced fish products
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)The aim of this thesis was to develop two protein enriched products based on haddock and silver smelt, reaching the level of total protein in the utilized fish raw material. Both products were enriched by whey protein ... -
Exploring Analytical Methods for Quality Control and Accurate Quantification of Major Biologically Active Components in Astragalus Radix
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020)Abstract Introduction Over the past decade, the worldwide consumption and sales of Traditional Chinese Medicine (TCM) herbs have grown enormously. Astragalus Radix (Chinese: Huang qi) (AR), the dried root of Astragalus ... -
Development of LC-MS/MS method for analysing immunosuppressants in whole blood for the purpose of TDM, with the novel application of SALLE in the sample preparation
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-07-06)The laboratory for Medical Biochemistry at Stavanger University Hospital (SUS) needed a new method for analysing tacrolimus, sirolimus, everolimus and cyclosporin A. A method was developed using the analytical principles ... -
Tacrine hybrids as multi-target-directed ligands against Alzheimer’s disease
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-07)World health organization estimates that nearly 9.9 million people develop dementia each year. Alzheimer disease (AD) is the most common form of dementia, and contributes to 60-70% of the cases. In addition to affecting ... -
Synthesis and Testing of Oil Field Scale Inhibitors
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)Scale formation is one of the major problems faced during production in the oil industry. A common method to control scale is the utilization of chemicals known as scale inhibitors (SIs). Several SIs are available commercially ... -
Effect of metformin and phenformin in acute myeloid leukemia cell lines MOLM-13 and HL-60
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-07)Cancer is a large group of diseases and a second leading cause of death globally with an estimated 9.6 million death in 2018 according to World Health Organization (WHO). It is an abnormal and uncontrollably growth of cells ... -
Synthesis of tacrine- and coumarin-isocryptolepine hybrids as potential dual binding site acetylcholinesterase inhibitors
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-08-10)This project presents the synthesis of tacrine and coumarin scaffolds armed with an alkyl-chain of varying length with an azido functionality and isocryptolepine scaffold armed with a terminal alkyne. The synthesis of ... -
Growth and inactivation of Bacillus pumilus with heat and high-pressure processing
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)The main objective of this study was to obtain knowledge about Bacillus pumilus B367 with relevance to food safety and investigate if B. pumilus B367 would be inactivated at lower temperatures for shorter time by applying ... -
Performance of Enzyme-Catalyzed Single-E and Dual-E Homeostatic Controllers
(Masteroppgave/UIS-TN-IKBM/2020;, Master thesis, 2020-06-15)Mathematical modeling has become an important tool in order to investigate the behavior of biological systems. The concept of homeostasis is central to our understanding how cells and organisms maintain an internal stability ... -
