Arachnoid cysts do not contain cerebrospinal fluid: A comparative chemical analysis of arachnoid cyst fluid and cerebrospinal fluid in adults
Berle, Magnus; Wester, Knut; Ulvik, Rune Johan; Kroksveen, Ann Cathrine; Haaland, Øystein; Amiry-Moghaddam, Mahmood; Berven, Frode S. (Peer reviewed; Journal article, 2010-06-10)Background Arachnoid cyst (AC) fluid has not previously been compared with cerebrospinal fluid (CSF) from the same patient. ACs are commonly referred to as containing "CSF-like fluid". The objective of this study was to ... -
Bloodlettings in Hemochromatosis Result in Increased Blood Lead (Pb) Concentrations
Yazdani, Mazyar; Distante, Sonia; Mørkrid, Lars; Ulvik, Rune Johan; Bolann, Bjørn Johan (Journal article; Peer reviewed, 2022)Hemochromatosis is a hereditary disorder, most often associated with mutations of the HFE (High FErrum) gene. If left untreated, it can result in severe parenchymal iron accumulation. Bloodletting is the mainstay treatment. ... -
Discovery and initial verification of differentially abundant proteins between multiple sclerosis patients and controls using iTRAQ and SID-SRM
Kroksveen, Ann Cathrine; Aasebø, Elise; Vethe, Heidrun; van Pesch, Vincent; Franciotta, Diego; Teunissen, Charlotte E.; Ulvik, Rune Johan; Vedeler, Christian A.; Myhr, Kjell-Morten; Barsnes, Harald; Berven, Frode (Peer reviewed; Journal article, 2013-01)In the present study, we aimed to discover cerebrospinal fluid (CSF) proteins with significant abundance difference between early multiple sclerosis patients and controls, and do an initial verification of these proteins ... -
Hyperferritinemia—a clinical overview
Sandnes, Miriam; Ulvik, Rune Johan; Vorland, Marta; Reikvam, Håkon (Journal article; Peer reviewed, 2021)Ferritin is one of the most frequently requested laboratory tests in primary and secondary care, and levels often deviate from reference ranges. Serving as an indirect marker for total body iron stores, low ferritin is ... -
The prevalence of anemia and iron deficiency is more common in breastfed infants than their mothers in Bhaktapur, Nepal
Chandyo, Ram Krishna; Henjum, Sigrun; Ulak, Manjeswori; Thorne-Lyman, Andrew L; Ulvik, Rune Johan; Shrestha, Prakash Sunder; Locks, Lindsey; Fawzi, Wafaie W.; Strand, Tor A. (Peer reviewed; Journal article, 2015)Background/Objectives: Iron deficiency anemia is a widespread public health problem, particularly in low- and middle-income countries. Maternal iron status around and during pregnancy may influence infant iron status. We ... -
Protein profiling reveals inter-individual protein homogeneity of arachnoid cyst fluid and high qualitative similarity to cerebrospinal fluid
Berle, Magnus; Kroksveen, Ann Cathrine; Haaland, Øystein; Aye, Thin T.; Opsahl, Jill Anette; Oveland, Eystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2011-05-20)Background: The mechanisms behind formation and filling of intracranial arachnoid cysts (AC) are poorly understood. The aim of this study was to evaluate AC fluid by proteomics to gain further knowledge about ACs. Two goals ... -
Quantitative proteomics comparison of arachnoid cyst fluid and cerebrospinal fluid collected perioperatively from arachnoid cyst patients
Berle, Magnus; Kroksveen, Ann Cathrine; Garberg, Hilde Kristin; Aarhus, Mads; Haaland, Øystein; Wester, Knut; Ulvik, Rune Johan; Helland, Christian Andre; Berven, Frode S. (Peer reviewed; Journal article, 2013-04-29)Background: There is little knowledge concerning the content and the mechanisms of filling of arachnoid cysts. The aim of this study was to compare the protein content of arachnoid cysts and cerebrospinal fluid by quantitative ...
