1. 1. Liver regeneration : With reference to malnutrition and growth factors

   Författare :Stefan Skullman; Linköpings universitet; []
   Nyckelord :cholecystokinin; energy substrates; epidermal growth factor; insulin-like growth factor I; liver composition; liver regeneration; malnutrition; pancreaticobiliary diversion; protein synthesis; rat; transfonning growth factor alpha; MEDICINE; MEDICIN;

   Sammanfattning : The liver has a unique capacity to regenerate after damage, irrespective of cause. The regulatory mechanisms of this regeneration are not fully known. Liver regeneration· is associated with rapid growth and thereby increased demands for energy and synthesis of new compounds. LÄS MER

3. 2. Ultrasound based shear wave elastography of the liver : a non-invasive method for evaluation of liver disease

   Författare :Marie Byenfeldt; Anders Elvin; Per Fransson; Odd Helge Gilja; Umeå universitet; []
   Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anthropometric measurement; diagnostic imaging; elasticity imaging technique; blood supply; BMI; body position; fatty liver; liver disease; hepatic steatosis; liver fibrosis; liver stiffness; obesity; postural change; pressure; probe; sex characteristic; shear wave elastography; skin-to-liver capsule distance; transducer and ultrasonography; Radiography; radiografi;

   Sammanfattning : Background: Detecting liver disease at an early stage is important, given that early intervention decreases the risk of developing cirrhosis and subsequently hepatocellular cancer (HCC). The non-invasive ultrasound-based shear wave elastography (SWE) has been used clinically for a decade to assess liver stiffness. LÄS MER

4. 3. Quantitative Evaluation of Contrast Agent Dynamics in Liver MRI

   Författare :Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Carsten Thomsen; Linköpings universitet; []
   Nyckelord :Liver; spleen; hepatobiliary system; liver function; MRI; DCE-MRI; Gd-EOBDTPA; Gd-BOPTA; pharmacokinetic; hepatocyte; relaxivity.; MEDICINE; MEDICIN;

   Sammanfattning : The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients.Ten healthy volunteers were examined with both contrast agents in a 1.

5. 4. Hormonal regulation of liver and tumor growth

   Författare :Ville Wallenius; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; cytokine; interleukin-6; tumor necrosis factor; primary liver growth promoter; cyproterone acetate; nafenopin; hepatocyte growth factor; HGF receptor; tumor; sarcoma; N-terminal; truncated;

   Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.

7. 5. Liver metastases from colorectal cancer. Different strategies and outcomes

   Författare :Valentinus Valdimarsson; Lund Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver metastases; Colorectal Neoplasms; Hepatectomy; Mortality; Treatment outcome; Retrospective studies; Sweden; Registries; Volume measurements; Repeat hepatectomy; liver surgery; Functional liver volume; Repeated operation; Recurrence;

   Sammanfattning : Patients with colorectal liver metastases (CRLM) increasingly undergo liver resections. The belief is that the resection or ablation of a tumor, when possible, is the only possibility of a cure. LÄS MER
