Background Umbilical hernias are common in patients with end-stage liver disease undergoing liver transplantation. Management of those persisting at the time of liver transplantation is important to define. Objective To evaluate the long-term results of patients undergoing simultaneous primary umbilical hernia repair (UHR) at the time of liver transplantation at a single institution. Method...

BACKGROUND Although postoperative infections have a significant impact on morbidity and mortality after orthotopic liver transplantation (OLT), less is known about their economic implications. In this study, we sought to identify risk factors and estimate the impact of surgical site infections on 1-year mortality, graft survival, and resource utilization after OLT. METHODS We studied 777 firs...

The subcutaneous space has been shown to be a suitable site for islet transplantation, however an abundance of islets is required achieve normoglycemia, often requiring multiple donors. loss due the hypoxic conditions experience during revascularization, resulting in apoptosis. Therefore, reduce therapeutic dosage pre-vascularization pursued. In this study, we highlight biomaterial-based approa...

Alternative islet transplantation sites have the potential to reduce the marginal number of islets required to ameliorate hyperglycemia in recipients with diabetes. Previously, we reported that T cell leukemia homeobox 1 (Tlx1)+ stem cells in the spleen effectively regenerated into insulin-producing cells in the pancreas of non-obese diabetic mice with end-stage disease. Thus, we investigated t...

CD81 is a surface-associated protein expressed in the membranes of mammalian cells. It has been suggested that CD81 interacts with hepatitis C virus E2 protein, and thus might facilitate the entry of HCV into hepatocytes. The envelope-binding site appears to involve amino acids (aa) 480-493 and 544-551 within the E2 glycoprotein. Little is known about the quasispecies genetic diversity of these...

patients and methods this retrospective cohort study included 405 renal transplant patients from kerman university of medical sciences hospital, kerman, iran from 2004 to 2010. kaplan-meier method was used to estimate survival rates of patients, and time-dependent cox regression was used to examine the effect of allograft failure on patient survival. results during 4.06 years (median) of follow...

Immune responses are suppressed in immunologically privileged sites, which may provide a unique opportunity to prolong allograft survival. However, it is unknown whether testicular immune privilege promotes transplantation tolerance. Mechanisms underlying immune privilege are also not well understood. Here we found that islet transplantation in the testis, an immunologically privileged site, ge...

The osteopetrotic (op/op) mouse lacks colony stimulating factor-1 (CSF-1) due to an inactivating mutation in the CSF-1 gene. Intramuscular transplantation of engineered myoblasts was used to introduce CSF-1 into the circulation of op/op mice. The CSF-1 cDNA was introduced into C2C12 mouse myoblasts in culture using retroviral mediated gene transfer. Upon transplantation into the skeletal muscle...

In this study, we examined the efficacy of human umbilical cord blood mononuclear cells (hUCB-MCs), genetically modified with the VEGF and GDNF genes using adenoviral vectors, on posttraumatic regeneration after transplantation into the site of spinal cord injury (SCI) in rats. Thirty days after SCI, followed by transplantation of nontransduced hUCB-MCs, we observed an improvement in H (latency...

BACKGROUND Cryptococcosis occurring ≤30 days after transplantation is an unusual event, and its characteristics are not known. METHODS Patients included 175 solid-organ transplant (SOT) recipients with cryptococcosis in a multicenter cohort. Very early-onset and late-onset cryptococcosis were defined as disease occurring ≤30 days or >30 days after transplantation, respectively. RESULTS Very...
