Abstract
We examined the effectiveness of saline, Euro-Collins solution (EC), and ET-Kyoto solution (ET-K) as preservation media for the cold storage of feline ovaries. Ovaries were maintained in these media at 4°C for 24, 48, or 72 h until oocyte retrieval. The ET-K group exhibited a higher oocyte maturation rate than the saline group after 72 h of storage. Moreover, ET-K could sustain the competence of the feline oocytes to cleave after 48 h, and the morula formation rate of the ET-K group was higher than that of the other groups after 24 and 48 h. Furthermore, the ET-K group exhibited a higher blastocyst formation rate than the other groups after storage for 24 h, and only ET-K retained the developmental competence in blastocysts after 48 h of storage. In addition, regarding the cell numbers of the blastocysts, there was no significant difference among the tested groups. In conclusion, our results indicate that ET-K is a suitable preservation medium for feline ovaries.

Abstract
Ameliorating graft injury induced by ischemia and hypoxia, expanding the donor pool, and improving graft quality and recipient prognosis are still goals pursued by the transplant community. The preservation of organs during this process from donor to recipient is critical to the prognosis of both the graft and the recipient. At present, static cold storage, which is most widely used in clinical practice, not only reduces cell metabolism and oxygen demand through low temperature but also prevents cell edema and resists apoptosis through the application of traditional preservation solutions, but these do not improve hypoxia and increase oxygenation of the donor organ. In recent years, improving the ischemia and hypoxia of grafts during preservation and repairing the quality of marginal donor organs have been of great concern. Hemoglobin-based oxygen carriers (HBOCs) are “made of” natural hemoglobins that were originally developed as blood substitutes but have been extended to a variety of hypoxic clinical situations due to their ability to release oxygen. Compared with traditional preservation protocols, the addition of HBOCs to traditional preservation protocols provides more oxygen to organs to meet their energy metabolic needs, prolong preservation time, reduce ischemia–reperfusion injury to grafts, improve graft quality, and even increase the number of transplantable donors. The focus of the present study was to review the potential applications of HBOCs in solid organ preservation and provide new approaches to understanding the mechanism of the promising strategies for organ preservation.

Abstract
Vascular surgery in liver resection is a standard part of liver transplantation, but is also used in oncological liver surgery. Malignant liver tumors with vascular involvement have a poor prognosis without resection. Surgery is currently the only treatment to provide long-term survival in advanced hepatic malignancy. Even though extended liver resections are increasingly performed, vascular involvement with need of vascular reconstruction is still considered a contraindication for surgery in many institutions. However, vascular resection and reconstruction in liver surgery-despite being complex procedures-are safely performed in specialized centers. The improvements of the postoperative results with reduced postoperative morbidity and mortality are a result of rising surgical and anesthesiological experience and advancements in multimodal treatment concepts with preconditioning measures regarding liver function and systemic treatment options. This review focuses on vascular surgery in oncological liver resections. Even though many surgical techniques were developed and are also used during liver transplantation, this special procedure is not particularly covered within this review article. We provide a summary of vascular reconstruction techniques in oncological liver surgery according to the literature and present also our own experience. We aim to outline the current advances and standards in extended surgical procedures for liver tumors with vascular involvement established in specialized centers, since curative resection improves long-term survival and shifts palliative concepts to curative therapy.

Abstract
PURPOSE Although transplanting two kidneys from a single donor to two recipients has some advantages, the right and left kidneys are not anatomically identical; thus, a surgical procedure considering the anatomical features of the donor kidneys is needed when transplanting them into the opposite renal fossae. Based on vast experience, the surgical details of pig orthotopic kidney transplantation from one donor to two recipients was reported. METHODS When the right kidney was transplanted to the left renal fossa, the graft was inverted upside down, not backwards, thus ensuring that the anteroposterior relationship of the renal vessels was maintained and anatomically natural vascular anastomosis could be performed. RESULTS Using this technique, we could have developed a pig experimental model that is safe and has a high success rate, even for researchers in the middle of their training. This technique of inverting the graft upside down was reported in human kidney transplantation to make vascular anastomosis easier. CONCLUSIONS In pig orthotopic kidney transplantation from one donor to two recipients, an anatomically natural vascular anastomosis could be performed via inverted grafting when the right kidney was transplanted into the left renal fossa.

Abstract
Valvular diseases are common health problems that are strongly related to high morbidity and mortality; aortic valve allograft transplantation may be a promising way to improve survival and relieve symptoms. However, ideal tissue viability has not been observed with common valve cryopreservation methods, which could lead to apoptosis and necrosis in cryopreserved tissue. It has been observed that trehalose plays a positive role by acting to maintain cell structures and protect cells from stress responses. In this study, we studied the effects of trehalose in protecting rat valve tissue from the cooling process. We found improved higher cell function in rat valves treated with trehalose during cryopreservation than in those treated with dimethyl sulphoxide (DMSO). To further explore the mechanisms, we found that trehalose could down-regulate the expression of cleaved caspase-3, an important molecule involved in cell apoptosis. In addition, treatment with trehalose also decreased Glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP), the key proteins in the endoplasmic reticulum stress (ERS) process. Intriguingly, we observed that trehalose promotes cryoprotected rat valve cell autophagy via an mTOR-independent but p38 MAPK-dependent signaling pathway. Additionally, miR-221 and miR-32 have been implicated in such cell activities. In summary, our study offers a new and meaningful cryopreservation approach for valve allograft storage.

Abstract
Various preservation solutions are used for kidney, liver, pancreas, small intestine, and multiorgan recoveries and transplants. The effectiveness of these solutions, primarily measured by ability to preserve the organ and graft survival, was analyzed. The 2 most common solutions used for intra-abdominal organs are University of Wisconsin Solution (UW)/Viaspan and Histidine-tryptophan-ketoglutarate (HTK)/Custodiol solution. Outcomes for liver, pancreas, and kidney allografts preserved with these 2 solutions are similar. Although HTK solution shows conflicting results with respect to pancreatic cellular edema, researchers in several studies have noted that HTK solution may be more protective than UW solution against biliary complications in liver transplant. In kidney recoveries, HTK solution may be associated with higher graft loss and increased delayed graft function in marginal deceased donors but had lower incidence of delayed graft function in living donors when compared with UW. UW remains the reference standard for use during multiorgan recoveries but is experiencing strong competition from HTK and other alternative solutions. Some researchers suggest that Celsior's comparable results in abdominal organs and viability for thoracic organs makes it a strong competitor, especially in multiorgan recoveries. Each solution has benefits accompanied by disadvantages. Although it may not be feasible, when considering single-organ recoveries, consideration of alternative solutions may be warranted.

Abstract
Supplemental Digital Content is available in the text. Background: Ischemia exceeding 6 hours makes clinical limb replantation difficult and places the patient at risk of functional deficit or limb loss. We investigated the preservation of muscle function and morphology with solutions in rat hindlimb in vivo and in vitro. Methods: Quadriceps femoris muscles from luciferase transgenic rats were preserved for 24 hours at 4°C in extracellular-type trehalose containing Kyoto (ETK), University of Wisconsin (UW), or lactated Ringer’s (LR) solution (control). Muscle luminescence was measured with a bioimaging system. Amputated limbs of Lewis rats preserved with ETK, UW, or LR for 6 or 24 hours at 4°C were transplanted orthotopically. At week 8, terminal latency and amplitude were measured in the tibialis anterior muscle. The muscles were also analyzed histologically. Results: Isolated muscles preserved in ETK or UW had significantly higher luminescence than did muscles immersed in LR (P < 0.05). In the 6-hour-preserved limb transplantation model, although the 3 groups had almost the same terminal latency, electrical amplitude was significantly lower in the LR group. Histologically, muscles preserved with LR showed the most atrophic changes. In the 24-hour-preserved model, the survival rate of the LR group was 37.5% in contrast to 80% in the ETK and UW groups. Electrical signals were not detected in the LR group owing to severe muscle atrophy and fibrosis. The ETK and UW groups showed good muscle function electrophysiologically. Conclusions: Preservation solutions can protect muscle function and morphology in ischemia–reperfusion limbs and improve recipient survival rates after transplantation of long-term-preserved limbs.

Abstract
Demand for human primary hepatocytes is increasing, particularly for clinical trials of hepatocyte transplantation. However, due to the severe shortage of organ transplant donors, the source of cells for these endeavors is restricted to untransplantable livers, such as those from non-heart-beating donors and surgically resected liver tissues. To improve cell recovery from such sources after warm ischemia, we evaluated the efficacy of applying perfusion solutions, focusing on improvement of hepatocyte recovery. Warm ischemia was induced by clamping both portal vein and hepatic artery for 10 or 15 min in rats. The liver was perfused with either Euro-Collins (EC) or extracellular-type trehalose-containing Kyoto (ETK) solutions supplemented with an anticoagulant, either heparin or citrate phosphate dextrose solution (CPD), compared to Ca(2+), Mg(2+)-free Hanks solution. While the viability of recovered cells was 81.5 ± 4.2% and cell yield was 2.27 ± 0.53 × 10(8) in nonwarm ischemia controls (n = 11), these values were only 74.7 ± 2.9% and 0.38 ± 0.17 × 10(8), respectively, in the 10-min warm ischemia group, using the Hanks as the perfusion solution. Although the addition of heparin increased the live cell number only twofold (0.71 ± 0.40 × 10(8), n = 4), the best improvement was achieved by adding CPD to EC. This resulted in a recovery of 1.41 ± 0.50 × 10(8) in the 10-min ischemia group (n = 7) and 1.37 ± 0.28 × 10(8) in the 15-min group (n = 3). Macroscopic observation showed that blood had been completely flushed out by the solution, suggesting good restoration of the microcirculation in ischemic liver. Using ETK instead of EC resulted in a slight decrease in efficacy. These results demonstrate that CPD, as opposed to heparin, is effective in ensuring liver microcirculation and flushing out the blood and that EC is the best perfusion solution for obtaining hepatocytes from ischemic liver.

Abstract
Cold storage of kidneys before transplantation is problematic because of the limited survival time of the allografts. In this study, zinc-N-acetylcysteine (ZnNAC) was shown to be a potent endonuclease inhibitor and antioxidant, and it was tested as a potential additive to a cold storage solution for kidney preservation. Exposure of normal rat kidney NRK-52E cells to ZnNAC resulted in zinc delivery to the cells as determined by TFL-Zn fluorophore and partial protection of the cells against injury by cold storage in University of Wisconsin solution (UWS) as measured by propidium iodide assay. Ex vivo, rat kidneys demonstrated time- and temperature-dependent DNA fragmentation as assessed by TUNEL assay, indicating irreversible cell death. DNA fragmentation was faster in the medulla than in the cortex, and tubules were affected more than glomeruli. Perfusion of rat kidneys with cold ZnNAC solution in UWS significantly inhibited cell death both in the cortex and medulla at concentrations of 0.3-30 mM compared with UWS alone, with a maximum effect at 1-10 mM ZnNAC. Cold storage of the kidney significantly increased quantities of cleaved caspase-3 and endonuclease G (EndoG) in the tissue, which were abolished by 10 mM ZnNAC, indicating its ability to suppress both caspase-dependent and -independent cell death. Therefore, supplementation of UWS with ZnNAC can decrease DNA fragmentation and protect kidney allografts from cell death due to cold storage.

Abstract
OBJECTIVES The aim of this study was to examine the effect of phosphoenolpyruvate (PEP), a glycolytic intermediate, on organ damage during cold preservation of liver. METHODS An ex-vivo mouse liver cold-preservation model and an in-vitro liver injury model induced by hydrogen peroxide in HepG2 cells were leveraged. KEY FINDINGS PEP attenuated the elevation of aminotransferases and lactate dehydrogenase leakage during organ preservation, histological changes and changes in oxidative stress parameters (measured as thiobarbituric acid reactive substance and glutathione content) induced by 72 h of cold preservation of the liver. The effects were comparable with the University of Wisconsin solution, a gold standard organ preservation agent. The decrease in ATP content in liver during the cold preservation was attenuated by PEP treatment. PEP prevented the cellular injury and increases in intracellular reactive oxygen species in HepG2 cells. In addition, PEP scavenged hydroxyl radicals, but had no effect on superoxide anion as evaluated by an electron paramagnetic resonance spin-trapping technique. CONCLUSIONS PEP significantly attenuated the injury, oxidative stress and ATP depletion in liver during cold preservation. The antioxidative potential of PEP was confirmed by in-vitro examination. We suggest that PEP acts as a glycolytic intermediate and antioxidant, and is particularly useful as an organ preservation agent in clinical transplantation.

Abstract
Background The aim of this study was to investigate factors that may improve the condition of a marginal kidney preserved with a normothermic solution following cardiac death (CD) in a model of rat kidney transplantation (RTx). Methods Post-euthanasia, Lewis (LEW) donor rats were left for 1 h in a 23°C room. These critical kidney grafts were preserved in University of Wisconsin (UW), lactate Ringer's (LR), or extracellular-trehalose-Kyoto (ETK) solution, followed by intracellular-trehalose-Kyoto (ITK) solution at 4, 23, or 37°C for another 1 h, and finally transplanted into bilaterally nephrectomized LEW recipient rats (n = 4–6). Grafts of rats surviving to day 14 after RTx were evaluated by histopathological examination. The energy activity of these marginal rat kidneys was measured by high-performance liquid chromatography (HPLC; n = 4 per group) and fluorescence intensity assay (n = 6 per group) after preservation with UW or ETK solutions at each temperature. Finally, the transplanted kidney was assessed by an in vivo luciferase imaging system (n = 2). Results Using the 1-h normothermic preservation of post-CD kidneys, five out of six recipients in the ETK group survived until 14 days, in contrast to zero out of six in the UW group (p<0.01). Preservation with ITK rather than ETK at 23°C tended to have an inferior effect on recipient survival (p = 0.12). Energy activities of the fresh donor kidneys decreased in a temperature-dependent manner, while those of post-CD kidneys remained at the lower level. ETK was superior to UW in protecting against edema of the post-CD kidneys at the higher temperature. Luminescence intensity of successful grafts recovered within 1 h, while the intensity of grafts of deceased recipients did not change at 1 h post-reperfusion. Conclusions Normothermic storage with extracellular-type solution containing trehalose might prevent reperfusion injury due to temperature-dependent tissue edema.

Abstract
BACKGROUND This report summarizes outcomes of islet transplantation employing donors after cardiac death (DCD) between 2004 and 2007 as reported to the Japan Islet Transplantation Registry. METHOD Sixty-five islet isolations were performed for 34 transplantations in 18 patients with insulin-dependent diabetes mellitus, including two patients who had prior kidney transplantation. All but one donor (64/65) was DCD at the time of harvesting. RESULTS Factors influencing criteria for islet release included duration of low blood pressure of the donor, cold ischemic time, and usage of Kyoto solution for preservation. Multivariate analysis selected usage of Kyoto solution as most important. Of the 18 recipients, 8, 4, and 6 recipients received 1, 2, and 3 islet infusions, respectively. Overall graft survival defined as C-peptide level more than or equal to 0.3 ng/mL was 76.5%, 47.1%, and 33.6% at 1, 2, and 3 years, respectively, whereas corresponding graft survival after multiple transplantations was 100%, 80.0%, and 57.1%, respectively. All recipients remained free of severe hypoglycemia while three achieved insulin independence for 14, 79, and 215 days. HbA1c levels and requirement of exogenous insulin were significantly improved in all patients. CONCLUSION Islet transplantation employing DCD can ameliorate severe hypoglycemic episodes, significantly improve HbA1c levels, sustain significant levels of C-peptide, and achieve insulin independence after multiple transplantations. Thus, DCD can be an important resource for islet transplantation if used under strict releasing criteria and in multiple transplantations, particularly in countries where heart-beating donors are not readily available.

Abstract
Since the successful demonstration of the Edmonton protocol, islet transplantation has advanced significantly on several fronts, including improved pancreas preservation systems. In this study, we evaluated two different types of organ preservation solutions for human islet isolation. Modified Celsior (Celsior solution with hydroxyethyl starch and nafamostat mesilate; HNC) solution and modified Kyoto (MK) solution were compared for pancreas preservation prior to islet isolation. Islet yield after purification was significantly higher in the MK group than in the HNC group (MK = 6186 ± 985 IE/g; HNC = 3091 ± 344 IE/g). The HNC group had a longer phase I period (digestion time), a higher volume of undigested tissue, and a higher percentage of embedded islets, suggesting that the solution may inhibit collagenase. However, there was no significant difference in ATP content in the pancreata or in the attainability of posttransplant normoglycemia in diabetic nude mice between the two groups, suggesting that the quality of islets was similar among the two groups. In conclusion, MK solution is better for pancreas preservation before islet isolation than HNC solution due to the higher percentage of islets that can be isolated from the donor pancreas. MK solution should be the solution of choice among the commercially available solutions for pancreatic islet isolation leading to transplantation.

Abstract
BACKGROUND Previously, decreased organic anion transport through multidrug resistance protein 2 (Mrp2) was observed without any notable cell lysis, even when the livers were stored for 8 hours in University of Wisconsin solution (UW). The aim of this study was to examine the bile flow and its constituents, markers of graft dysfunction without necrosis in cold ischemic livers, using the following preservation media: UW, ET-Kyoto solution (ET-K) and histidine-tryptophan-ketoglutarate solution (HTK). MATERIALS AND METHODS Rat livers were stored at 4 degrees C for 8 hours in the preservation media, and reperfused to collect the bile and determine their constituents. Glycyrrhizin (GL) and/or glutathione (GSH) were added to the media as necessary. The transport efficiency of Mrp2 was assessed by the biliary excretion of 5-carboxyfluorescein (CF), a fluoroprobe excreted from Mrp2. The Intracellular distribution of Mrp2 was determined by immunostaining. RESULTS Livers stored for 8 hours exhibited significantly decreased bile production and biliary glutathione (GSH) levels without notable cell lysis. CF excretion was significantly delayed in all solutions. However, these markers were remarkably improved by the redistribution of Mrp2 from the cytoplasm to the canalicular membrane, when the livers were exposed to UW in the presence of GL. Moreover, livers exposed to the Kyoto and HTK solutions increased their bile production and organic anion transport in the presence of GL and GSH. CONCLUSION These results suggest that the addition of GL and GSH to preservation solutions improves bile production and biliary organic anion transport by increasing Mrp2 localization to the bile canaliculi in post-cold ischemic livers.

Abstract
ET-Kyoto solution (ET-K) is an extracellular-type organ preservation solution containing the cytoprotective disaccharide, trehalose. A previous study reported the supplement of dibutyryl cyclic adenosine monophosphate (db-cAMP) in conventional ET-K to attenuate lung ischemia-reperfusion injury. In this study, the efficacy of this modified ET-K for liver preservation was investigated by comparison with University of Wisconsin solution (UW). ET-K was supplemented with db-cAMP (2 mmol/L). Lewis rats were randomly assigned to two groups, and liver grafts were flushed and stored at 40C for 24 h with ET-K or UW before syngeneic liver transplantation. The graft function and histological changes at 4 h posttransplant as well as 7-day survival were evaluated. Recipient rat survival rate was significantly higher in the ET-K group than in the UW group. Preservation in ET-K resulted in a significant reduction in serum parenchymal transaminase level and promotion of bile production in comparison with UW. The serum hyaluronic acid level, an indicator of sinusoidal endothelial cell injury, was significantly lower after ET-K preservation than that in UW. Histologically, at 4 h after transplantation, the liver grafts preserved in UW solution demonstrated a greater degree of injury than those in ET-K, which appeared to be apoptosis, rather than necrosis. The continuity of the sinusoidal lining was better preserved in ET-K than in UW. In conclusion, ET-K supplemented with db-cAMP is superior to UW in rat liver preservation. This modified ET-K might therefore be a novel candidate for the procurement and preservation of multiple organs.

Abstract
Recent dramatic improvements in clinical islet cell transplantation demonstrated by the Edmonton group have increased the demand for this treatment, and donor shortage could become a major problem. Utilization of marginal donors could alleviate the donor shortage, and non-heart-beating donors (NHBDs) might be good resources. The University of Pennsylvania group demonstrated that it was possible to isolate islets from NHBDs, and the group actually transplanted islets from NHBDs, for the first time. The patient became insulin-independent; however, there had been no more cases using NHBDs until our group initiated islet transplantations from NHBDs in Japan. In order to utilize NHBDs effectively, we modified the standard islet isolation method. These modifications included minimizing the warm ischemic time, the use of trypsin inhibition during isolation, carrying out density measurement before purification and the use of a less toxic islet purification solution. With these modifications we were able to transplant nine of ten islet preparations from ten NHBDs (90%), into five type-1 diabetic patients. The first transplantation was performed on April 7, 2004 (the first time in Japan), and this patient became insulin-independent after the second islet transplantation (first time in Japan). All patients showed improved glycemic control and reduced insulin requirements, without hypoglycemic events. We also performed living-donor islet transplantation, with our modified islet isolation protocol, on January 19, 2005. The improved islet isolation protocol enabled us to perform effective islet transplantations from NHBDs, and it also enabled us to perform the living-donor islet transplantation.

Abstract
We have developed a new organ preservation solution called extracellular-type trehalose-containing Kyoto (ET-Kyoto) solution. ET-Kyoto solution has been applied in clinical lung transplantation. The patient was a 49-year-old woman with diffuse panbronchiolitis. She underwent bilateral lobar lung transplantation from living donors. Each lobe was flushed with ET-Kyoto solution. After reperfusion, PaO(2) with inhalation of 100% oxygen was more than 500 Torr. Posttransplantation course was uneventful. Despite the relatively short ischemic time of this case report, ET-Kyoto solution may be feasible and safely applied in clinical lung transplantation.
