  1. 1. Monitoring of Splanchnic Regional Perfusion : An Experimental Study of New Application and Validation

    Författare :Itaru Koga; Lennart Christiansson; Lars Wiklund; Björn Biber; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; Splanchnic circulation; Regional ischemia; Hepatic artery buffer response; Air tonometry; Intraperitoneal; Reflectance pulse oximetry; Hepatic venous oxygen saturation; Lactate; PCO2 gap; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård;

    Sammanfattning : Systemic infection, major surgery, trauma and many other causes can lead to impaired organ function. Compensated shock is not detected by global hemodynamic and oxygen measurements, as they take no account for regional variations. LÄS MER

  3. 2. Low density lipoprotein (LDL) heterogeneity : implications for cardiovascular disease and genetic influence

    Författare :Camilla Skoglund Andersson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Low density lipoprotein; gradient gel electrophoresis; intima-media thickness; atherosclerosis; myocardial infarction; low density lipoprotein oxidation; cholesteryl ester transfer protein; lipoprotein lipase; hepatic lipase; apolipoprotein E; apolipoprotein B; microsomal triglyceride transfer protein; genetics; lipoproteins; metabolism;

    Sammanfattning : The low density lipoprotein (LDL) particle population is heterogeneous with regard to several structural and functional properties that may influence its atherogenic potential. A preponderance of small, dense LDL is associated with an increased risk of coronary heart disease (CHD), and also predicts future CHD events. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. 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.

  7. 5. Implantation-Site Dependent Differences in Engraftment and Function of Transplanted Pancreatic Islets

    Författare :Joey Lau; Per-Ola Carlsson; Leif Jansson; Carina Carlsson; Caroline Kampf; Annika Tibell; Uppsala universitet; []
    Nyckelord :Cell biology; Type 1 diabetes; pancreatic islets; human islets; islet transplantation; vascular engraftment; revascularization; implantation-site; microenvironment; vascular density; insulin release; pro insulin biosynthesis; glucose oxidation; Cellbiologi;

    Sammanfattning : Transplanting pancreatic islets into the liver through the portal vein is currently the most common procedure in clinical islet transplantations for treating patients with brittle type 1 diabetes. However, most islet grafts fail within a 5-year period necessitating retransplantation. LÄS MER
