Abstract
BACKGROUND Probable effects of living donor liver transplantation on the wellbeing of the donor and psychological difficulties are necessary to be understood. OBJECTIVE To assess the quality of life of living donors after liver donation. METHODS 140 living donors who underwent hepatectomy between 2012 and July 2015 were enrolled in this study. Donors were asked to complete the Short Form 36-question Health Survey (SF-36) through face to face or by telephone interview. RESULTS The mean±SD age of donors at transplantation was 32.1±7.3 years; 83 (59.3%) of donors were female. 134 (95.7%) were married. The mean±SD BMI was 23.8±3.5 (kg/m2). "Mother-to-child" was the most frequent relationship (n=79, 56.4%). 22 (15.7%) complications were reported by participants. The mean±SD score of Physical Component Summary and Mental Component Summary were 48.8±14.6 and 50.1±6.9, respectively. CONCLUSION Most living donors sustain a near average quality of life post-donation. It seems that living donation does not negatively affect the quality of life.

Abstract
BACKGROUND Hepatocyte transplantation using isolated human hepatocytes is an alternative source that can be used for the treatment of metabolic diseases and acute liver failure as a time bridge to liver transplantation. These cells can also be used for bioartificial liver systems and in vitro study of drug toxicity. OBJECTIVE To determine which cold preservation solution is better maintain the liver function. METHODS We prepared 4 cold preservation solutions made of different combination of antioxidants, chelating, membrane protective, and anti-apoptotic agents as well as inhibitor of cyclophilin D. For hepatocyte isolation, we used livers obtained from unused deceased donor livers and the liver of patients with Crigler-Najjar syndrome who were candidates of partial liver transplantation. After culture and cold preservation, the level of albumin, and urea production were measured as indices of liver functionality. RESULTS We found that albumin production significantly decreased after cold preservation in solution 1. There was no significant difference in urea production after cold preservation in solution 1 compared with control 24 h. No significant differences in albumin production were found after cold storage in solution 2 and solution 4 compared with control 24 h. Urea production significantly decreased after cold storage in solutions 2 and 4 compared with control 24 h. As a whole albumin and urea production were significantly decreased after cold preservation. Although albumin and urea production were decreased after cold preservation, but the results of albumin production of two solutions were not significantly different from that of the control group (p=0.109 and 0.951). CONCLUSION Cold preservation of cultured human hepatocytes in solution 2 and solution 4 could maintain the function of albumin production better than other cold preservation solutions in our experiments; solution 1 was more effective on urea production of cultured human hepatocytes at 4 °C for 24 h. To determine if these hepatocytes are suitable candidates for transplantation, further studies should be performed.

Abstract
Abstract
STUDY QUESTION
Could small molecules (SM) which target (or modify) signaling pathways lead to increased proliferation of undifferentiated spermatogonia following chemotherapy?
SUMMARY ANSWER
Inhibition of transforming growth factor-beta (TGFb) signaling by SM can enhance the proliferation of undifferentiated spermatogonia and spermatogenesis recovery following chemotherapy.
WHAT IS KNOWN ALREADY
Spermatogonial stem cells (SSCs) hold great promise for fertility preservation in prepubertal boys diagnosed with cancer. However, the low number of SSCs limits their clinical applications. SM are chemically synthesized molecules that diffuse across the cell membrane to specifically target proteins involved in signaling pathways, and studies have reported their ability to increase the proliferation or differentiation of germ cells.
STUDY DESIGN, SIZE, DURATION
In our experimental study, spermatogonia were collected from four brain-dead individuals and used for SM screening in vitro. For in vivo assessments, busulfan-treated mice were treated with the selected SM (or vehicle, the control) and assayed after 2 (three mice per group) and 5 weeks (two mice per group).
PARTICIPANTS/MATERIALS, SETTING, METHODS
We investigated the effect of six SM on the proliferation of human undifferentiated spermatogonia in vitro using a top–bottom approach for screening. We used histological, hormonal and gene-expression analyses to assess the effect of selected SM on mouse spermatogenesis. All experiments were performed at least in triplicate and were statistically evaluated by Student’s t-test and/or one-way ANOVA followed by Scheffe’s or Tukey’s post-hoc.
MAIN RESULTS AND THE ROLE OF CHANCE
We found that administration of SB431542, as a specific inhibitor of the TGFb1 receptor (TGFbR1), leads to a two-fold increase in mouse and human undifferentiated spermatogonia proliferation. Furthermore, injection of SB to busulfan-treated mice accelerated spermatogenesis recovery as revealed by increased testicular size, weight and serum level of inhibin B. Moreover, SB administration accelerated both the onset and completion of spermatogenesis. We demonstrated that SB promotes proliferation in testicular tissue by regulating the cyclin-dependent kinase (CDK) inhibitors 4Ebp1 and P57 (proliferation inhibitor genes) and up-regulating Cdc25a and Cdk4 (cell cycle promoting genes).
LIMITATIONS, REASONS FOR CAUTION
The availability of human testis was the main limitation in this study.
WIDER IMPLICATIONS OF THE FINDINGS
This is the first study to report acceleration of spermatogenesis recovery following chemotherapy by administration of a single SM. Our findings suggest that SB is a promising SM and should be assessed in future clinical trials for preservation of fertility in men diagnosed with cancer or in certain infertility cases (e.g. oligospermia).
STUDY FUNDING/COMPETING INTEREST(S)
This study was supported by Royan Institute and National Institute for Medical Research Development (NIMAD, grant no 963337) granted to H.B. The authors have no conflict of interest to report.

Abstract
The pivotal role of the extracellular matrix (ECM) as both a cause and consequence of liver fibrosis is striking. However, mechanotransducer molecules and profibrogenic factors induced by liver stiffness are still unclear. The current study aimed to investigate liver stiffness and its correlation with the expression of the transcriptional coactivator with PDZ-binding motif (TAZ) and serum osteopontin (OPN) in human cirrhosis. In this case-control study, liver tissue stiffness was determined using atomic force microscopy in cirrhotic livers (n = 38) of different etiologies and in controls (n = 10). Immunohistochemical and qRT-PCR analyses were performed to analyze TAZ expression. Besides, western blotting and ELISA were performed to assess liver Indian hedgehog and serum OPN levels, respectively. Liver stiffness, TAZ expression, and hepatic gene expression and serum protein levels of OPN were significantly increased in patients with cirrhosis compared with the control groups (all P < 0.001), specifically in autoimmune- and alcohol-related cirrhosis. In cirrhotic patients, liver stiffness was significantly associated with the expression of nuclear TAZ and OPN. The correlation between matrix stiffness as a mechanical property, TAZ as a potential mechanotransducer, and OPN as a matricellular factor suggests possible effects of mechanical features of the ECM on the expression of the aforementioned profibrogenic markers, which is predominant in autoimmune- and alcohol-related cirrhosis.

Abstract
OBJECTIVES Liver transplant has been shown to be a good treatment option for patients with nonresectable tumors that are limited to liver and that do notrespond to medicaltreatment. In this study, our aim was to share our experience in management of patients with neuroendocrine tumors and liver metastasis by liver transplant with and without more extensive surgical interventions. MATERIALS AND METHODS We performed a 6-year (2011- 2017) retrospective study of data from the Namazi Hospital Transplant Research Center. Inclusion and exclusion criteria were determined based on pretransplant policy in our center. Our study included 15 patients with mean age of 33.3 years. RESULTS Of the 15 patients included, 53.3% (n = 8) had liver transplant alone, 26.6% (n = 4) had multiorgan transplant, 6.66% (n = 1) underwentWhipple procedure and liver transplant, and 6.66% (n = 1) had segmental ileal resection and liver transplant. Six early mortalities occurred during the posttransplant hospital stay, and 2 patients with multiorgan transplant died in the followup period. In addition, 1 patient needed retransplant during follow-up due to chronic rejection. CONCLUSIONS In patients with neuroendocrine tumors, the therapeutic approach to the liver metastasis and the prognosis can be determined based on the natural history of the disease, severity and progression of symptoms,tumor biology, location, and differentiation. Early diagnosis and management are needed to allow less invasive treatment protocols, which could result in more favorable outcomes.

Abstract
OBJECTIVES Primary hyperoxaluria type 1 is an autosomal recessive disorder that causes overproduction and urinary excretion of oxalate. Liver transplant has been suggested as a treatment for primary hyperoxaluria type 1 since the defective enzyme is expressed in the liver. This study aimed to investigate results of combined liver and kidney, sequential, and preemptive livertransplantin patients with primary hyperoxaluria type 1. MATERIALS AND METHODS In this cohort study, we followed patients with primary hyperoxaluria type 1 who underwent liver transplant at our centerin Shiraz, Iran. Clinical and laboratory data of patients were gathered, and major outcomes, including renal failure after liver transplant, rejection, and mortality were recorded. Survival of patients was analyzed by the Kaplan-Meier method. RESULTS Our study included 24 patients. There were 16 male (66.6%) and 8 female (33.33%) patients. Thirteen patients were in the pediatric age group (age < 18 y), and 11 patients were adults (age ≥ 18 y). Thirteen patients underwent sequential transplant, 8 patients underwent combined liver and kidney transplant, and 3 patients underwent preemptive transplant. All patients received organs from deceased donors. There were no statistically significant differences in mortality, rejection, and hemodialysis after transplant between those with sequential transplant and those with combined liver and kidney transplant (P > .05). CONCLUSIONS Liver transplant can be considered a treatment for patients with primary hyperoxaluria type 1. Combined liver and kidney transplant and preemptive liver transplant could be proper options for these patients.

Abstract
Ginsenoside Rd (GS-Rd), one of the main pharmacologically active components of ginseng, has shown the potential to stabilize mitochondrial membrane integrity and decrease apoptotic death in neuronal and non-neuronal cells. The present study aimed to evaluate the effect of this bioactive molecule on the apoptosis-associated cell death in human pancreatic islets. In this regard human pancreatic islets were isolated and grouped for the treatment with GS-Rd. The isolated islets were treated with different concentrations of GS-Rd. After 24 and 72 h of incubation, the islets were evaluated in terms of viability, BAX, BCL2, and insulin gene expression, BAX, BCL2, and caspase-3 protein expression, apoptosis, and glucose-induced insulin/C-peptide secretion. Our results revealed the islet survival was significantly decreased in the control group after 72 h of incubation. However, GS-Rd inhibited the progress of the islet death in the treated groups. TUNEL staining revealed that the preventive effect of this molecule was caused by the inhibition of apoptosis-associated death. In this regard, the activation of caspase-3 was down-regulated in the presence of GS-Rd. GS-Rd did not exhibit undesirable effects on glucose-induced insulin and C-peptide stimulation secretion. In conclusion, GS-Rd inhibited the progress of death of cultured human pancreatic islets by diminishing the apoptosis of the islet cells.

Abstract
Islets transplantation, as a treatment of type 1 diabetes, faces challenges, including the loss of islets in the process of isolation and pre-transplantation due to cellular stresses-induced apoptosis. Accordingly, the optimization of culture plays a decisive role in the transplantation success. In this study, we evaluated the effect of nobiletin on the cultured human islets. Isolated human islets were treated by different concentrations of nobiletin and cultured for 24 and 72 hours. Then, the islets viability, apoptosis, insulin and C-peptide secretion, and apoptosis markers were evaluated. Also, the production of reactive oxygen species (ROS), hypoxia inducible factor 1 alpha (HIF-1α), and its target genes in the islets were examined. Our findings showed that the islets were encountered with hypoxia and oxidative stress after isolation and during culture. These insults induced apoptosis and reduced viability during culture period. Moreover, the secretion of insulin and C-peptide decreased. Nobiletin treatments significantly improved the islets survival through reduction of HIF-1α and ROS production and suppression of apoptosis, along with increased islets function. Islet protective effect of nobiletin might be related to its anti-oxidant, anti-apoptotic and insulinotropic properties. Hence, in order to achieve viable and functional islets for clinical transplantation, the application of nobiletin during pre-transplantation period is useful.

Abstract
OBJECTIVES Detection of hepatic steatosis in donors is an important step for selection of a suitable liver allograft in living-donor transplant. This study aimed to investigate the role of hepatic computed tomography volumetry as a noninvasive method for detection of hepatic steatosis in living liver donors. MATERIALS AND METHODS In a cross-sectional study, individuals who had undergone liver biopsy as a pretransplant checkup before living-donor liver transplant were included. The segmental liver volumes were measured by computed tomography scan with intravenous contrast enhancement. RESULTS Our study included 179 individuals. Mean total volume of the liver was 1705.2 ± 256.5 cm³ in those with steatohepatitis and 1419.4 ± 241.2 cm³ in those without steatohepatitis (P < .001). Higher total volume of the liver (odds ratio of 1.005; 95% confidence interval, 1.001-1.010; P = .012) and total liver volume-to-standard liver volume ratio (odds ratio of 1.090; 95% confidence interval, 1.021-1.163; P = .009) were independent predictors of steatohepatitis. A cutoff value of 1531 cm³ for total liver volume was a predictor of presence of steatohepatitis in liver biopsies of donors (sensitivity = 83%; specificity = 71%; area under the curve = 0.809; P < .001). CONCLUSIONS Computed tomography volumetry may be considered as an auxiliary noninvasive method for estimation of hepatic steatosis/steatohepatitis and may be used as a guide to select donor candidates for liver biopsy.

Abstract
OBJECTIVES Although transplant teams understand the effects of donor characteristics on liver transplant outcomes, few studies have investigated the quality of livers obtained from poisoned donors. The aim of this study was to compare livers procured from poisoned donors with a matched control group. MATERIALS AND METHODS Liver transplant outcomes from poisoned donors and from donors with trauma-induced death (as the control group) were compared using data of an Organ Procurement Unit from 2000 to 2013. Procured livers were evaluated via histology findings before transplant. Recipient characteristics were assessed in both groups, and immediate and medium-term (up to 5 years after transplant) survival rates were compared with the use of Kaplan-Meier analyses and log-rank tests. RESULTS Over a 13-year organ donation program, 1485 livers from brain dead patients were donated. Among them, 115 poisoned donors were evaluated for liver grafts; of these, 74 successful liver transplants were performed. In the poisoned donors, the incidence of reversed cardiac arrest was 54.1%. Likewise, acute kidney injury was detected in 14.9% of the patients, and 16.2% needed urgent dialysis either for clearance of the toxic agents or for treatment of acute kidney injury. No significant differences were observed in 1- to 5-year survival rates, and log-rank test also showed a significance level of 0.83. CONCLUSIONS Proper case selection strategies can be implemented to expand the donor pool, including use of poisoned donors. Hence, poisoning is not a contra-indication for a referral, which could lead to decreased mortality for patients requiring a liver transplant.

Abstract
The conversion of simple steatosis into nonalcoholic steatohepatitis (NASH) in patients with nonalcoholic fatty liver disease (NAFLD) has attracted many attentions in recent years. The role of the hedgehog (HH) pathway in the regulation of lipogenesis has been addressed in the literature. This study aimed to investigate the levels of the sonic hedgehog (SHH) and Indian hedgehog (IHH) ligands and the correlation of these ligands with levels of proteins involved in the transforming growth factor-β1 (TGF-β1) pathway, as well as the evaluation of the transcriptional coactivator with PDZ binding motif (TAZ) expression in human simple steatosis, NASH cirrhosis, and controls. Patients were divided into two groups: the first group consisted of patients diagnosed with simple steatosis (n = 16) and the second group included those diagnosed with NASH cirrhosis (n = 15). As a control group, 18 histologically normal liver tissues were collected in this study. The expression of the TGF-β1pathway components and SHH and IHH ligands were analyzed by means of the quantitative real-time polymerase chain reaction and western blot analyses. A significant decrease was found in the hepatic expression of the SHH, IHH, and TGF-β1 pathways along with the expression of TAZ in tissue specimens with simple steatosis in comparison with patients affected by NASH cirrhosis and controls. Also, the levels of SHH and IHH proteins were significantly correlated with the expression of proteins involved in the TGF-β1 pathway. Moreover, the expression of the HH pathway ligands was positively associated with the expression of TAZ, supporting the notion that TAZ may play a role in the activation of the HH pathway thereby regulating the expression of its ligands. It seems that in patients with NAFLD, the downregulation of the HH pathway ligands may stem from steatosis; however, at the same time, it may prevent the conversion of simple steatosis into NASH in patients with liver diseases. © 2019 IUBMB Life, 71(9):1382-1390, 2019.

Abstract
BACKGROUND Mesenchymal stem cells are one of the most interesting cell sources used in regenerative medicine. OBJECTIVE In the present study, we isolated and characterized the mesenchymal stem cells from various compartments of human adipose tissue and tunica adventitia layer of the arteries. METHODS Tissue explant culture was done from various compartments of the human adipose tissue and tunica adventitia layer of the arteries, including adipose tissue far from the vessels, perivascular tissues that are completely attached to the vessels, and tunica adventitia layer of the arteries. After the cell culture, characterization of the cells was determined at 3rd-5th passages. Flow cytometry was performed for antigen expression analysis of CD34, CD45, CD44, CD90, CD29, CD73, and CD105. For the evaluation of cell differentiation potential, adipogenic and osteogenic differentiation was conducted under appropriate protocols. RESULTS The cells were positive for CD44, CD90, CD29, and CD73 and negative for CD34, CD45, and CD105. Adipogenic and osteogenic differentiation potentials were different among the cells from various compartments. The cells derived from perivascular tissue demonstrated better adipogenic and osteogenic differentiation. CONCLUSION It is essential to characterize the cells from different tissues and compartments for different purposes in regenerative medicine.

Abstract
OBJECTIVES We aimed to determine outcomes and predictors of intraoperative-detected portal vein thrombosis in liver transplant recipients. MATERIALS AND METHODS We retrospectively analyzed 806 adult liver transplant recipients from Shiraz, Iran, to determine those with intraoperative-detected portal vein thrombosis. Patients with this complication were compared with age- and sex-matched patients without this complication. Background diseases, surgery parameters, hospital admission, reoperation, rethrombosis, acute rejection, and use of antico-agulants were assessed. Cox proportional hazards, logistic regression, and random classification forest and random survival forest plots were used for data analyses. RESULTS Mean age of patients was 44.7 ± 13.2 years. Patients with intraoperative-detected portal vein thrombosis (n = 91; 11.3%) had mortality ratio of 2.9 (range, 1.0-8.6) and 2-year survival of 78% versus 2-year survival rate of 92% in patients without this disease. Median time of survival in patients with this complication who died was 2 weeks versus 10 months in patients who died and did not have this complication. Random classification forest plots showed that high fasting blood sugar, autoimmune hepatitis, low prothrombin time, and cryptogenic cirrhosis were (in order) the main predictors of this complication. Random survival forest plots revealed that low prothrombin time, having intraoperative-detected portal vein thrombosis, Model for End Stage Liver Disease score, primary sclerosing cholangitis, diabetes mellitus, and hepatocellular carcinoma were (in order) the main predictors of death in liver transplant recipients. Low body mass index was associated with mortality in patients with intraoperative-detected portal vein thrombosis (by Cox proportional hazards). CONCLUSIONS One of every 9 liver transplant patients had intraoperative-detected portal vein thrombosis. Hazard of death was 2.9, and death occurred far earlier in patients with this complication. Improvements in diabetes mellitus care, prothrombin time, Model for End-Stage Liver Disease score, and body mass index may improve outcomes of these patients.

Abstract
BACKGROUND Solid pseudopapillary tumor of pancreas (SPTP) is a rare tumor of the pancreas which mostly occurs in young women. Since its first description in 1969, more than 500 cases have been reported. There have been just 2 case reports and 1 review (7 cases) from Iran. In this study, we reported our experience with 22 patients with SPT from the largest pancreaticobiliary center in Southern Iran. METHODS During 6 years (2012-2017), 22 cases of SPTP were operated on in our center. All of these cases were recruited and after confirmation of the pathological diagnosis, clinical charts were evaluated and all the clinicopathologic findings as well as outcome of the surgery were evaluated. RESULTS Among the 22 patients, 20 were female and 2 were males. The age range was 15-52 years and the tumor sizes were 3.5 to 17 cm. All of the tumors had preoperative diagnosis by imaging modalities and were operated on with no complication or recurrences. Just one case showed liver metastasis. All of the patients with SPTP in this study were alive and in good condition. CONCLUSION SPTP is not very rare in our center. In young patients presenting with pancreatic mass, especially in female patients, one of the most important diagnoses is SPTP. Conservative surgery and tumor excision is satisfactory and patients show excellent prognosis even after liver metastasis.

Abstract
BACKGROUND AND PURPOSE Islet transplantation is considered as a promising approach in the treatment of diabetes type 1. In this regard, optimal culture of the pancreatic islets is promising in the success of transplantation. In the present study, the effect of olesoxime, as an antiapoptotic substance, was evaluated on human islet culture. EXPERIMENTAL APPROACH The pancreatic islets were isolated by mechanical and enzymatic techniques. After overnight recovery, the islets were treated by different concentrations of olesoxime for 24 and 72 h. Then, they were examined in terms of viability, apoptosis, genes and proteins expression including BAX, BCL2, active caspase-3, and insulin. Moreover, the islets function was evaluated through the glucose-induced insulin and C-peptide secretion assay. KEY RESULTS Our findings showed that the islets increased in apoptosis and the decreased in viability after 72 h; also, insulin and C-peptide secretion reduced. However, in the presence of olesoxime, BAX/BCL2 ratio and the activation of caspase-3 were decreased. Therefore, olesoxime could improve the viability of the islets with the decrease of apoptosis. CONCLUSION The application of olesoxime can reduce the stressful condition for the islets in vitro and subsequently improve their viability and functionality.

Abstract
OBJECTIVES Human leukocyte antigen-G is an immuno-modulatory factor that affects acute allograft rejection and autoimmune diseases such as type 1 diabetes mellitus. In this study, possible associations between human leukocyte antigen-G 14-bp insertion/deletion polymorphism and acute pancreas rejection were investigated. MATERIALS AND METHODS Human leukocyte antigen-G genotyping was assessed in 102 Iranian pancreas transplant recipients (including 41 with acute rejection and 61 with nonacute rejection). Results were compared with 100 individuals in a normal control group. RESULTS No significant differences in genotype frequencies of human leukocyte antigen-G 14-bp insertion / deletion were observed in recipients who had acute rejection episodes. On the other hand, the insertion / insertion genotype was a risk factor for susceptibility to type 1 diabetes mellitus (odds ratio = 3.82, 95% confidence interval, 1.37- 11.22; P = .005). CONCLUSIONS Our results provided evidence revealing that the human leukocyte antigen-G insertion / insertion genotype might be involved in the pathogenesis of type 1 diabetes mellitus.

Abstract
BACKGROUND Most pancreatic masses are primary ductal adenocarcinomas; however, with the advent of new imaging studies and increasing survival of cancer patients, there are more cases with the diagnosis of secondary metastatic cancer to the pancreas. There is no study regarding cancer metastases to the pancreas from Iran. In this study, we retrieved all of the cases with the diagnosis of secondary cancer of pancreas in the affiliated hospitals of Shiraz University of Medical Sciences. METHODS In 5 years (2012-2017), we evaluated all cases with the diagnosis of any pancreatic tumors and extracted all of the demographic and clinicopathologic findings of the cases with the diagnosis of metastatic pancreatic tumors from the clinical charts and pathology reports. RESULTS For the duration of 5 years in our center, there were 131 cases of pancreatic tumors with different diagnoses, 9 of which were diagnosed as metastatic cancers from other organs. Two cases were diagnosed with gastric adenocarcinoma, 2 cases were colonic adenocarcinoma, one case was lung small cell carcinoma, 2 cases were renal cell carcinoma (RCC) and one case was gastrointestinal stromal tumor (GIST). The mesenchymal metastatic cancer to the pancreas has been a case of pleomorphic sarcoma of retroperitoneum. CONCLUSION Pancreas is not a common location for metastases; however, colon, stomach, kidney and lung seem to be the most common primary tumors with metastases to the pancreas. Our report is the first study about pancreatic metastatic tumors from Iran.

Abstract
BACKGROUND Liver transplantation is the only treatment for end-stage and genetic liver diseases. The main burden of this treatment is the shortage of both living and cadaveric liver donors. An alternative treatment is using liver cell transplantation, which can be obtained from unused livers for transplantation. These hepatocytes should be kept ready in viable and functional situation in a frozen state to be instantly used when they would be needed. In our previous experience, we had isolated hepatocytes from unused livers. OBJECTIVE To find a preserving solution for increasing viability and function of the isolated hepatocytes that are stored to be transplanted. METHODS 9 cadaveric donor livers, which were not used for transplantation due to various causes such as severe steatosis, were selected to isolate hepatocytes. Various cold storage solutions were tried to find the best temperature for more viability and functionality for preservation of hepatocytes. University of Wisconsin (UW) solution and Williams E media were used as control media. 2 anti-apoptotic and anti-oxidative solutions, i.e., α-lipoic acid and ursodeoxycholic acid (UDCA), were used as cold preservatives solutions. The numbers of viable hepatocytes were estimated by trypan blue method; the functionality was assessed by the cells ability to produce urea. RESULTS The highest number of viable and functional hepatocytes was obtained from freshly isolated cells. However, after preservation, the number of these viable hepatocytes and their functionality were not significantly different in cold storage solutions comparing to the control media used. Functionality of the isolated hepatocytes stored in UW with and without UCDA solution was similar to freshly isolated hepatocytes. CONCLUSION Preservatives with anti-apoptotic and antioxidant activity could not increase the number of viable hepatocytes. Functionality of cold storing hepatocytes could be preserved similar to freshly isolated hepatocytes by UW solution with and without UCDA.

Abstract
AIM Portal vein thrombosis (PVT) is a common complication amongst patients with liver cirrhosis. The PVT risk factors and its impact on post liver transplant outcome has not been well defined, yet. This study aimed to investigate PVT prevalence, its risk factors and influence on early and long-term outcomes after liver transplantation. METHODS Adult (>18 years) patients with liver cirrhosis undergoing liver transplantation between March 2013 to March 2015 were included. Presence or absence of PVT was recorded at transplant. PVT risk factors in patients with liver cirrhosis and its impact on early and long-term outcomes were analysed. RESULTS Portal vein thrombosis was diagnosed in 174 patients (17.3%). Large oesophageal varices (grade II and III vs grade I) (OR: 2.5; 95% CI: 1.46-4.26; P = 0.001), diabetes mellitus before transplantation (OR: 2.03; 95% CI: 1.13-3.64; P = 0.017) and cryptogenic-NASH (OR: 1.36; 95% CI: 1.08-1.72; P = 0.008) as a cause of underlying liver disease were the independent risk factors for PVT. PVT (OR: 2.05; 95% CI: 1.10-3.81; P = 0.023) was an independent predictor of early (within 90 days) posttransplant mortality, but did not influence long-term survival. CONCLUSION Portal vein thrombosis prevalence is high in pretransplant period. NASH related cirrhosis and diabetes mellitus might be risk factors for PVT. More intense screening of these patients for PVT is warranted.

Abstract
Cryopreservation of testicular tissue before cancer therapy for fertility preservation in prepubertal boys with cancer is of great interest in reproductive medicine. Isolation of spermatogonial stem cells (SSCs) from cryopreserved tissues would be a suitable cell source to re-establish spermatogenesis after cancer therapy. We herein establish optimized protocols for cryopreservation of human testicular tissue and isolation of SSCs from cryopreserved tissue. We developed a freezing protocol that provided high testicular cell viability and supported structural integrity and tubular epithelium coherence similar to fresh tissue. Then, we established a protocol that allowed efficient isolation of functional SSCs from cryopreserved tissues. Isolated cells were found on the testicular basement membrane after xenotransplantation. Our results demonstrated the preservation of testicular tissue structure and high cell viability with efficient isolation of SSCs after testicular cryopreservation, which is promising for future therapeutic applications in fertility preservation.

Abstract
OBJECTIVES Liver transplant is the most effective treatment modality for patients with end-stage liver disease, metabolic disorders, hepatic malignancy, and acute liver failure. When a graft fails after primary liver transplant, retransplant of the liver remains the only option. Here, we report the past 12-year experience of the Shiraz Transplant Center regarding liver retransplant. MATERIALS AND METHODS This is a retrospective cohort study of a 12-year period (2004-2015) of the Shiraz Center in Iran. RESULTS Of the 3107 patients who had a liver transplant during the study period, 58 retransplants were performed (1.86%) in 57 patients. The leading cause of retransplant was primary nonfunction in 24 patients (41.4% of retransplant cases and 0.77% of all liver transplant cases). The second leading cause of retransplant was vascular complications in 25 patients (23 with hepatic artery thrombosis and 2 with portal vein thrombosis), accounting for 43.1% of retransplant cases and 0.80% of all liver transplant cases. In addition, 5 patients (8.6%) had retransplant for rejection, which accounted for 0.16% of all liver transplant cases. Four patients with retransplant (6.9%) had recurrence of primary disease, which accounted for 0.12% of all liver transplant cases. Most liver retransplants occurred early (≤ 30 days after primary transplant) at the Shiraz Transplant Center. Five-year survival rate after retransplant was 35%, and retransplant for hepatic artery thrombosis was more common in children. CONCLUSIONS Because most patients required retransplants in the early period after primary transplant, the decision for retransplant must be considered carefully with full multidisciplinary evaluation and only in skilled hands. Retransplant in subgroups of patients with little chance of a successful outcome should be avoided.
