Detection and Characterization of Circulating Tumor Cells in Early Breast Cancer
(Masteroppgave/UIS-TN-IMN/2016;, Master thesis, 2016-06)Background: Detection of circulating tumor cells (CTCs) has demonstrated prognostic significance in metastatic breast cancer. This is less studied in early breast cancer due to the rarity of such cells in early disease and ... -
Detection of Borrelia bacteria using real-time PCR
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06-15)Lymes disease (LD) caused by bacteria in the Borrelia genus is the most commonly known vector borne disease on the northern hemisphere. There are at least 10 human pathogenic Borrelia species known to date, five of which ... -
Detection of oxidative stress in tissue homogenate from krill exposed to oil
(Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-07-14)Krill are small crustacean animals, living all over the world. They are key organisms in the marine food web. The petroleum industry releases oil to the sea with the produced water and by accidental oil spill, and there ... -
Determination of protein composition in whey fractions by molecular spectroscopy, gel electrophoresis and mass spectrometry
