OBJECTIVE To investigate effect of warm ischemia after cardiac death on activation of TLR9 pathway in porcine liver. METHODS Donor of cardiac death (DCD) model was established with Duroc, Landrace, Large White crossbred pigs. Liver tissues from the animals were harvested at 0, 5, 10, 15, 25 and 30 minutes after warm ischemia for analysis of expression of TLR9, IRF7, IFN-β, and TNF-α at mRNA a...

Background & Target: Ischemia Reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. In this study, the effect of pentoxyfylline on bcl2 gene expression changes and cell injury in kidney of rat following Ischemia Reperfusion were evaluated.Methods: In this experimental study, 20 male wistar rats with average weight of...

INTRODUCTION Partial nephrectomy is the standard of care for localized renal tumors. However, bleeding and warm ischemia time are still controversial when laparoscopic surgeries are carried out. Herein, we aim to compare the outcomes from laparoscopic partial nephrectomy with and without the use of biological glue with purified bovine albumin and glutaraldehyde (BioGlue ®). MATERIALS AND METH...

The effects of warm machine perfusion preservation of liver grafts donated after cardiac death on the intracellular three-dimensional ultrastructure of the organelles in hepatocytes remain unclear. Here we analyzed comparatively the ultrastructure of the endomembrane systems in porcine hepatocytes under warm ischemia and successive hypothermic and midthermic machine perfusion preservation, a ty...

Warm ischemia-reperfusion injury remains a crucial issue in transplantation following the cardiac death of donors. Previously, we showed that surfactant inhalation during warm ischemia mitigated ischemia-reperfusion injury. This study investigated the mechanisms of surfactant inhalation protection of the warm ischemic lung after reoxygenation with ventilation alone. In an isolated rat lung vent...

Early revascularization is cardinal for successful replantation of proximal limb amputations. Prolonged ischemia time potentially leads to reperfusion syndrome and morbidity. The dilemma persists regarding safe duration of cold ischemia time for replantation. The study was conducted to evaluate retrospectively the outcomes of major replantation in terms of limb survival, reperfusion events, mor...

The present study evaluated and compared the effects of SRI 63-441, a potent platelet activating factor antagonist, superoxide dismutase (SOD), an oxygen free radical scavenger, and ibuprofen, a cyclooxygenase inhibitor on hepatic function after 90 minutes of warm ischemia. After warm ischemia, livers were harvested and underwent 90 minutes of warm, oxygenated, sanguinous perfusion on an isolat...

HYPOTHESIS The posttransplantation renal function outcomes between consecutive open donor and laparoscopic donor nephrectomies (LDNs) are similar and affect living donation. DESIGN Using the medical records of renal living donor-recipient pairs, 36 consecutive open donor nephrectomies were compared with the subsequent 100 LDNs. Data collected on donor characteristics included demographics (ag...
