Insufficient is the evidence for safe use of elderly donors in adult-to-adult living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcomes of right lobe LDLT by donor age (≥55 vs. <55 years). All living donors who underwent right hepatectomy at the authors' institution between March 2008 and December 2015 were divided into 2 groups: group A with an age ≥ 55 and group B with an age < 55. The selection criteria for elderly donor were preservation of middle hepatic vein, remnant liver volume ≥30%, and no or mild fatty liver...

BACKGROUND: Kidneys derived from brain-dead (BD) donors have lower graft survival rates compared to kidneys from living donors. Complement activation plays an important role in brain death. The aim of our study was therefore to investigate the effect of C1-inhibitor (C1-INH) on BD-induced renal injury. METHODS: Brain death was induced in rats by inflating a subdurally placed balloon catheter. Thirty minutes after BD, rats were treated with saline, low-dose or high-dose C1-INH...

Spheroid cultures have been often used to simulate and understand in situ biological occurrences with potential to be further applied to therapeutic approaches, such as cell transplantation. However, traditional lab-scale techniques hardly reached the needed large scale production of cell spheroids, thus limiting their versatility in many biomedical fields. Microscale technologies have rapidly improved in the last decade, and contributed to the large scale production of cell spheroids with high controllability and reproducibility...

BACKGROUND: A Personal Health Record (PHR) is an online application that allows patients to access, manage, and share their health data. PHRs not only enhance shared decision making with healthcare providers, but also enable remote monitoring and at-home-collection of detailed data. The benefits of PHRs can be maximized in insulin dose adjustment for patients starting or intensifying insulin regimens, as frequent self-monitoring of glucose, self-adjustment of insulin dose, and precise at-home data collection during the visit-to-visit period are important for glycemic control...

AIM: PNPLA3 I148M polymorphism (rs738409 C>G) is the most important and the best known polymorphism for nonalcoholic fatty liver disease (NAFLD). However, little is known about the effect of this polymorphism on NAFLD after liver transplantation (LT). We aimed to evaluate the association between this polymorphism and post-LT NAFLD. METHODS: We designed a prospective case-control study. Among adult recipients who underwent LT between April 2014 and October 2015, those whose whole blood were preoperatively collected for genotyping in both recipients and coupled donors and those who have undergone protocol biopsy at post-LT 1 year were enrolled...

BACKGROUND: Minimally invasive surgery has been validated to be a new standard in living donor hepatectomy for adult-to-pediatric transplantation with less morbidity [1]. Laparoscopic donor hepatectomy can reduce the major concerns about pain and morbidity associated with open surgery and a slow return to daily activities of donors [2]. Herein, we present one case of totally laparoscopic living donor left hepatectomy including the middle hepatic vein (MHV). DONOR AND METHOD: A 37-year-old mother volunteered to donate to her 3-year-old son with biliary atresia (PELD score 7)...

Umbilical cord blood (CB) banks usually freeze and store CB for clinical transplantation using conventional controlled-rate freezer or the automated BioArchive system. The aim of this study is to compare the quality of CB cryopreserved with conventional and automated methods and to make clear the cause of the quality difference between the two methods. The experiment used 80 CB units: 40 were conventionally cryopreserved and the remainder were cryopreserved with a BioArchive. After thawing, the following measures of CB quality were compared: recovery rates of cell count, cell viability of total nucleated cells (TNCs), mononuclear cells (MNCs), and CD34+ cells, as well as colony-forming unit-granulocyte/macrophage (CFU-GM) content...

The mechanistic target of rapamycin (mTOR) is a central regulator of growth and proliferation and mTOR inhibition is a promising therapy for a variety of diseases and disorders. Inhibition of mTOR complex I (mTORC1) with rapamycin delays aging and increases healthy longevity in laboratory animals and is used clinically at high doses to prevent organ transplant rejection and to treat some forms of cancer. Clinical use of rapamycin is associated with several unwanted side effects, however, and several strategies are being taken to identify mTORC1 inhibitors with fewer side effects...

BACKGROUND: Compound FK506 is an immunosuppressant agent that is frequently used to prevent rejection of solid organs upon transplant. However, nephrotoxicity due to apoptosis and inflammatory response mediated by FK506 limit its usefulness. In this study, the protective effect of Korean Red Ginseng (KRG) against FK506-induced damage in LLC-PK1 pig kidney epithelial cells was investigated. METHODS: LLC-PK1 cells were exposed to FK506 with KRG and cell viability was measured...

BACKGROUND: Ex vivo lung perfusion (EVLP) enables assessment of marginal donor lungs for transplantation, with similar clinical outcomes to conventional lung transplantation. We investigated whether cell death-related proteins in the EVLP perfusate could predict primary graft dysfunction (PGD) after transplantation. METHODS: M30 (indicating epithelial apoptosis), M65 (indicating total epithelial cell death), and high mobility group box 1 (HMGB-1, related to cell death and inflammation) protein levels in EVLP perfusate were measured by enzyme-linked immunosorbent assay and correlated with clinical outcomes...

Cell migration and molecular mechanisms during healing of damaged vascular or muscle tissues are emerging fields of interest worldwide. The study herein focuses on evaluating the role of allogenic adipose-derived mesenchymal stem cells (ADMSCs) in restoring damaged tissues. Using a hindlimb ischemic mouse model, ADMSC-mediated induction of cell migration and gene expression related to myocyte regeneration and angiogenesis were evaluated. ADMSCs were labeled with GFP (ADMSC-GFP). The proximal end of the femoral blood vessel of mice (over 6 months of age) are ligated at two positions then cut between the two ties...

Large database studies detailing the risk of perioperative cardiovascular complications after pancreas transplant has been limited, perhaps because these outcomes are not captured by transplant registries. Greater data on the incidence and risks of such outcomes could provide additional insight for referring physicians and inform potential recipients of their risk. We performed a serial, cross-sectional analysis of the National Inpatient Sample, the largest publicly available inpatient database in the United States, to assess for the risk of cardiovascular complications after pancreas transplants in the United States from 2003 to 2012 (n = 13,399)...

BACKGROUND: The accurate estimation of liver volume and right/left ratio in donor candidates is critical, but there is no method using portal vein (PV) flow. METHODS: Of 125 donor candidates, right/left liver volume ratio was estimated using ultrasound (US)-PV area ratio and Doppler US-PV flow ratio, and the results were compared with CT volumetry. We analyzed these results in 76 donors who underwent hemihepatectomy. We evaluated diagnostic values of Doppler US-PV flow for <30% remnant liver volume high-risk donors, and compared liver volume by Doppler US-PV flow with actual graft weight...

The rhesus macaque induced pluripotent stem cell (riPSC) line, UCLAi090-A (riPSC90), was generated from rhesus embryonic fibroblast (REF) cells called REF90. REF90 cells and the riPSC90 line were authenticated by short tandem repeat analysis and had a normal male (42, XY) karyotype. The riPSC90 line expressed markers of self-renewal including OCT4, NANOG, TRA-1-81 and SSEA4, and generated teratomas after transplantation into immunocompromised mice. riPSC90 could be used in parallel with riPSC89, which was derived from REFs cultured from a different rhesus macaque embryo (Sosa et al...
