  8. Content type: Research

    Liver sinusoidal endothelial cells (LSECs) are specialized scavenger cells, with crucial roles in maintaining hepatic and systemic homeostasis. Under normal physiological conditions, the oxygen tension encount...

  10. Content type: Case Report

    Most focal nodular hyperplasia (FNH) cases are diagnosed by chance. We studied a case of pre-FNH. We used glutamine synthase as an immunohistochemical marker for perivenous zones.

    Citation: Comparative Hepatology 2008 7:2

    Published on:

  11. Content type: Research

    Portacaval shunting in rats produces a reduction of hepatic oxidant scavenging ability. Since this imbalance in hepatic oxidant/antioxidant homeostasis could coexist with systemic changes of oxidant stress/ant...

    Authors: Maria-Angeles Aller, Maria-Inmaculada García-Fernández, Fernando Sánchez-Patán, Luis Santín, José Rioja, Raquel Anchuelo, Jaime Arias and Jorge-Luis Arias

    Citation: Comparative Hepatology 2008 7:1

    Published on:

  12. Content type: Research

    The availability of non-rodent animal models for human cirrhosis is limited. We investigated whether privately-owned dogs (Canis familiaris) are potential model animals for liver disease focusing on regenerative ...
