0729. Interstitial changes in spleen during sepsis
Svendsen, Øyvind Sverre; Stangeland, Lodve; Elvevoll, Bjørg; Gjertsen, Bjørn Tore; Skavland, Jørn; Wiig, Helge; Tenstad, Olav; Husby, Paul (Conference object; Peer reviewed, 2014-09-26) -
Effect of Topical Anaesthetics on Interstitial Colloid Osmotic Pressure in Human Subcutaneous Tissue Sampled by Wick Technique
Guthe, Hans Jørgen Timm; Nedrebø, Torbjørn; Tenstad, Olav; Wiig, Helge; Berg, Ansgar (Peer reviewed; Journal article, 2012-02-14)Objectives: To measure colloid osmotic pressure in interstitial fluid (COPi) from human subcutaneous tissue with the modified wick technique in order to determine influence of topical application of anaesthetics, dry vs. ... -
High-salt diet causes osmotic gradients and hyperosmolality in skin without affecting interstitial fluid and lymph
Nikpey Esfahlan, Elham; Karlsen, Tine Veronica; Rakova, Natalia; Titze, Jens M.; Tenstad, Olav; Wiig, Helge (Peer reviewed; Journal article, 2017-04)The common notion is that the body Na+ is maintained within narrow limits for fluid and blood pressure homeostasis. Several studies have, however, shown that considerable amounts of Na+ can be retained or removed from the ... -
Image-based assessment of microvascular function and structure in collagen XV- and XVIII-deficient mice
Brekke, Cecilie; Løkka, Guro; Heljäsvaara, Ritva; Taxt, Torfinn; Pavlin, Tina; Sormunen, Raija T.; Pihlajaniemi, Taina; Curry, Fitz-Roy E.; Tenstad, Olav; Reed, Rolf K. (Peer reviewed; Journal article, 2014-01)Collagen XV and XVIII are ubiquitous constituents of basement membranes. We aimed to study the physiological roles of these two components of the permeability barrier non-invasively in striated muscle in mice deficient in ... -
Increased microvascular permeability in mice lacking Epac1 (Rapgef3)
Kopperud, Reidun Kristin; Rygh, Cecilie Brekke; Karlsen, Tine Veronica; Krakstad, Camilla; Kleppe, Rune; Høivik, Erling Andre; Bakke, Marit; Tenstad, Olav; Selheim, Frode; Liden, Åsa; Madsen, Lise; Pavlin, Tina; Taxt, Torfinn; Kristiansen, K.; Curry, FE; Reed, Rolf K.; Doskeland, Stein Ove (Peer reviewed; Journal article, 2017-02)Aim: Maintenance of the blood and extracellular volume requires tight control of endothelial macromolecule permeability, which is regulated by cAMP signalling. This study probes the role of the cAMP mediators rap guanine ... -
Interstitial fluid: the overlooked component of the tumor microenvironment?
Wiig, Helge; Tenstad, Olav; Iversen, Per Ole; Kalluri, Raghu; Bjerkvig, Rolf (Peer reviewed; Journal article, 2010-07-23)Background: The interstitium, situated between the blood and lymph vessels and the cells, consists of a solid or matrix phase and a fluid phase, together constituting the tissue microenvironment. Here we focus on the ... -
Interstitial IgG antibody pharmacokinetics assessed by combined in vivo- and physiologically-based pharmacokinetic modelling approaches
Eigenmann, Miro Julian; Karlsen, Tine Veronica; Krippendorff, Ben-Fillippo; Tenstad, Olav; Fronton, Ludivine; Otteneder, Michael B.; Wiig, Helge (Peer reviewed; Journal article, 2017-12)For most therapeutic antibodies, the interstitium is the target space. Although experimental methods for measuring antibody pharmacokinetics (PK) in this space are not well established, thus making quantitative assessment ... -
A New Method for Isolation of Interstitial Fluid from Human Solid Tumors Applied to Proteomic Analysis of Ovarian Carcinoma Tissue
Haslene-Hox, Hanne; Oveland, Eystein; Berg, Kaja Christine Graue; Kolmannskog, Odd; Woie, Kathrine; Salvesen, Helga Birgitte; Tenstad, Olav; Wiig, Helge (Peer reviewed; Journal article, 2011-04-26)Major efforts have been invested in the identification of cancer biomarkers in plasma, but the extraordinary dynamic range in protein composition, and the dilution of disease specific proteins make discovery in plasma ... -
Proteomic analysis of formalin-fixed paraffin-embedded glomeruli suggests depletion of glomerular filtration barrier proteins in two-kidney one-clip hypertensive rats
Finne, Kenneth; Vethe, Heidrun; Skogstrand, Trude; Leh, Sabine Maria; Dahl, Tone Dolva; Tenstad, Olav; Berven, Frode S.; Reed, Rolf K.; Vikse, Bjørn Egil (Peer reviewed; Journal article, 2014-08-16)Background It is well known that hypertension may cause glomerular damage, but the molecular mechanisms involved are still incompletely understood. Methods In the present study, we used formalin-fixed paraffin-embedded ... -
Quantification of the concentration gradient of biomarkers between ovarian carcinoma interstitial fluid and blood
Haslene-Hox, Hanne; Madani, Amina; Berg, Kaja Christine Graue; Woie, Kathrine; Salvesen, Helga Birgitte; Wiig, Helge; Tenstad, Olav (Peer reviewed; Journal article, 2014-12)Background: Tumor interstitial fluid (TIF) rather than plasma should be used in cancer biomarker discovery because of the anticipated higher concentration of locally produced proteins in the tumor microenvironment. ...
