The aim of this study was to investigate the differences in portal hemodynamics between whole liver transplantation and living donor liver transplantation (LDLT). Twenty patients who underwent LDLT (the L group) and 42 patients who underwent whole liver transplantation (the W group) were enrolled, and colored Doppler ultrasonography was performed preoperatively and on postoperative days (PODs) 1, 3, 5, 7, 30, and 90. The changes in the portal blood flow velocity (PBV) and portal blood flow volume (PBF) were monitored. The graft and spleen sizes were measured with angiographic computed tomography, and upper endoscopy was used to measure esophageal varices on PODs 14, 30, and 90. Although the portal venous pressure (PVP) decreased after graft implantation, it was higher in the L group with a smaller graft size ratio (25.7 ± 5.1 cm H₂O for the L group and 18.5 ± 4.6 cm H₂O for the W group, P < 0.05). PBF and PBV increased in both the W and L groups on POD 1 after transplantation; however, the PBF and PBV peaks were significantly higher in the W group. The postoperative PVP and graft volume were greatly related to PBF on POD 1. Grafts in the L group regenerated rapidly after the operation, and the volume increased from 704 ± 115 to 1524 ± 281 mL as early as 1 month after transplantation. A rapid improvement in splenomegaly was observed in both groups. An improvement in esophageal varices was observed in the W group on POD 14 after transplantation, whereas no change was observed in the L group. The portal venous flow in patients with portal hypertension showed a high perfusion state after LDLT, but in contrast to whole liver transplantation, the PVP elevation after LDLT postponed the closing time of the collateral circulation and affected the recovery from splenomegaly.

Objective: To discover the potential association between diminished intraoperative average SctO levels and postoperative neurodevelopmental delays among patients after pediatric living-donor liver transplantation.
Study Design: Patients undergoing living-donor liver transplantation were recruited for this trial. The neurodevelopment status of patients was assessed using the Ages Stages Questionnaires.

Organ transplantation is a life-saving intervention that enhances the quality of life for patients with end-stage organ failure. However, long-term immunosuppressive therapy is required to prevent allogeneic graft rejection, which inadvertently elevates the risk of post-transplant malignancies, especially for liver transplant recipients with a prior history of liver cancer. In response, the emerging field of transplant oncology integrates principles from oncology and immunology to improve outcomes for patients at high risk of tumor occurrence or recurrence following transplantation.

Background: Hepatocellular carcinoma (HCC) is the most common subtype of primary liver cancer with varied incidence and epidemiology worldwide. Sorafenib is still a recommended treatment for a large proportion of patients with advanced HCC. Different patterns of treatment responsiveness have been identified in differentiated hepatoblastoma HepG2 cells and metastatic HCC SNU449 cells.

Occupational exposure to aromatic amines is a major risk factor for urinary bladder cancer. Our previous studies showed that acetoaceto--toluidine, which is produced using -toluidine as a raw material, promotes urinary bladder carcinogenesis in rats. We also found high concentrations of -toluidine, a human bladder carcinogen, in the urine of acetoaceto--toluidine-treated rats, indicating that urinary -toluidine derived from acetoaceto--toluidine may play an important role in bladder carcinogenesis.

Introduction: Grafts with alcohol-associated liver disease (ALD) subjected to prolonged cold ischaemia from donors after brain death (DBD) are typically unsuitable for transplantation. Here, we investigated the role of growth hormone (GH) in livers with ALD from DBDs and its relationship with vascular endothelial growth factor A (VEGFA) and VEGFB.
Methods: Livers from rats fed ethanol for 6 weeks and with brain death (BD) were cold stored for 24 h and subjected to reperfusion.
