  2. 1. The Hepatobiliary Transport of Rosuvastatin In Vivo

    Author : Ebba Bergman; Hans Lennernäs; Ulf Bondesson; Jack Cook; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rosuvastatin; Biliary excretion; Transport inhibition; Pharmacokinetics; Drug-drug interactions; Hepatobiliary transport; Organic anion transporting polypeptide; OATP; Statins; Gemfibrozil; Cyclosporine; Imatinib; Rifampicin; Canalicular transport; Sinusoidal transport; Hepatic uptake; Hepatic extraction; Biopharmacy; Biofarmaci; Biopharmaceutics; biofarmaci;

    Abstract : In vivo studies of hepatobiliary disposition are challenging. The hepatobiliary system is complex, as its physiological localization, complex cellular structure with numerous transporters and enzymes, and the interindividual variability in protein expression and biliary flow will all affect the in vivo disposition of a drug under investigation.

  5. 3. Magnetic Resonance Imaging of the Hepatobiliary System Using Hepatocyte-Specific Contrast Media

    Author : Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Lennart Blomqvist; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic radiology; Diagnostisk radiologi;

    Abstract : There are two Gadolinium-based liver-specific contrast media for Magnetic Resonance Imaging on the market, Gd-BOPTA (MultiHance®, Bracco Imaging, Milan, Italy) and Gd-EOB-DTPA (Primovist®, Bayer Schering Pharma, Berlin, Germany). The aim of this study in two parts was to evaluate the dynamics of biliary, parenchymal and vascular enhancement using these contrast media in healthy subjects. READ MORE

  6. 4. Biopharmaceutical investigations of doxorubicin formulations used in liver cancer treatment : Studies in healthy pigs and liver cancer patients, combined with pharmacokinetic and biopharmaceutical modelling

    Author : Ilse R Dubbelboer; Hans Lennernäs; Erik Sjögren; Hartmut Derendorf; Uppsala universitet; []

    Abstract : There are currently two types of drug formulation in clinical use in the locoregional treatment of intermediate hepatocellular carcinoma (HCC). In the emulsion LIPDOX, the cytostatic agent doxorubicin (DOX) is dissolved in the aqueous phase, which is emulsified with the oily contrast agent Lipiodol® (LIP). READ MORE

  7. 5. Autoimmune hepatitis : life, death and in-between

    Author : Åsa Danielsson Borssén; Mårten Werner; Soo Aleman; Umeå universitet; []

    Abstract : Background Autoimmune hepatitis (AIH) is a chronic autoimmune liver disease that is overrepresented in women (75% of cases). Studies have described a 10-year survival after diagnosis near to that of the general population, but less is known about the long-term survival. READ MORE
