In this paper instrumental methods of carbon dioxide (CO₂) detection in biological material were compared. Using cis-[Cr(C₂O₄)(pm)(OH₂)₂]⁺ cation as a specific molecular biosensor and the stopped-flow technique the concentrations of CO₂ released from the cell culture medium as one of final products of pyruvate decomposition caused by hydrogen peroxide were determined. To prove the usefulness of...

Introduction: Postoperative neurological deficit is the most devastating complication after thoracoabdominal aortic aneurysm repair. Despite demonstrated neuroprotective effects of estradiol, its protective efficacy against spinal cord ischemia-reperfusion and underlying mechanisms are not yet elucidated. Methods: Two groups, each of 10 New Zealand white male rabbits, were studied. Control grou...

Lung transplantation is a well-accepted life-saving treatment for end-stage lung diseases. However, the short-term and long-term success of lung transplantation is hindered by multiple factors such as the shortage of organ donors, primary graft dysfunction, life-long immunosuppression and chronic graft dysfunction. Gene transfection presents a potential molecular therapeutic solution to these p...

Purpose: Ischemic preconditioning (IPC) has been used to protect myocardial cells against ischemiareperfusion injury and is recently utilized for improving exercise performance. It is unknown whether remote IPC (RIPC) to tissues not involved in exercise can induce similar exercise improvements and what “dose” of IPC is necessary to induce exercise performance benefits. This study determined if ...

The present 15 days study was undertaken to evaluate the cardioprotective potential of the prenylated isoflavones osajin and pomiferin isolated from the infructences of Maclura pomifera, Moraceae, against ischemia-reperfusion induced injury in rat hearts as a model of antioxidant-based composite therapy. The study was performed on isolated, modified Langendorff-perfused rat hearts and the ische...

background: serial measurement of  hepatitis b virus (hbv) dna levels in the liver and its relation with liver damage and serum hbv dna levels are guide to begin and/or end a treatment course. this study evaluated the relationship between liver hepatitis b dna viral load with liver histology in patients with chronic hepatitis b (hbv). methods:  thirty patients with chronic anti-hbe positive hep...

post-transplant lymphoproliferative disorder is a lymphocyte proliferating disease, usually of b cell origin, and rarely of t cell. involvement of liver itself in liver transplant recipients as the primary organ is not common. herein we report our experience in two patients who primarily presented in the allografted liver, both of whom were promptly diagnosed after liver biopsy and treated succ...

conclusions liver metastasis of neuroendocrine tumors in iran presents in a very similar manner as that seen in western countries. in about 89% of cases with liver-net, complete imaging, clinical, and pathological studies can help to identify the primary origin of the liver-net, which is very important in the patient’s management. results the most common primary site of metastatic gi-net to the...

Liver or hepatic transplantation (LT) is the replacement of a diseased liver with part or whole healthy liver from another person (allograft). Human liver transplants were first performed by Thomas Starzl in the United States and Roy Calne in Cambridge, England in 1963 and 1967, respectively. Liver transplantation is a viable treatment option for end-stage liver disease and acute liver failure....
