Abstract
Haloacetonitriles (HANs) are unregulated disinfection by-products that are more toxic than regulated species. Therefore, efficient decomposition of HAN precursors prior to disinfection is crucial for allaying the potential HAN-induced health risks. This study investigated the key roles of ultraviolet-activated persulfate (UV/PS) treatment in alleviating HAN formation. The effects of UV/PS treatment were evaluated by correlating with the characteristics of organic matter in surface water and comparing with conventional UV/H2O2 treatment. Upon irradiating raw water samples and a Suwannee River humic acid solution spiked with 10 mM PS or H2O2 with 254 nm UV light, UV/PS treatment was found to be more potent than UV/H2O2 in mitigating the HAN production and degrading organic substances; moreover, UV/PS treatment effectively decreased the dissolved organic nitrogen (DON) content. In contrast, UV/H2O2 treatment did not induce any noticeable reduction in DON level. Furthermore, both UV/PS and UV/H2O2 treatments reduced the dichloroacetonitrile (DCAN) formation potential (FP), leading to strong correlations with the degradation of aromatic and humic-acid-like compounds. Notably, UV/PS treatment efficiently decreased the FP of bromochloroacetonitrile (BCAN) and dramatically reduced that of dibromoacetonitrile (DBAN) after a sharp increase; however, UV/H2O2 treatment gradually increased the DBAN-FP. Bromide was activated by sulfate radicals during UV/PS treatment, negatively correlating with the BCAN-FP and DBAN-FP, indicating that the formation of reactive bromine species increased the DBAN-FP; however, excessive oxidation possibly led to the recovery of inorganic bromine for decreasing the BCAN-FP and DBAN-FP. Additionally, UV/PS treatment effectively suppressed toxicity owing to its high reduction rate for brominated HANs; in contrast, UV/H2O2 treatment resulted in less significant BCAN and DBAN reductions, leading to minimal net reduction in toxicity. Overall, UV/PS treatment was remarkably effective at diminishing the toxicity of brominated HANs, underscoring its potential to mitigate drinking-water-related health risks.

Abstract
The conventional yeast (Saccharomyces cerevisiae) is the most studied yeast and has been used in many important industrial productions, especially in bioethanol production from first generation feedstock (sugar and starchy biomass). However, for reduced cost and to avoid competition with food, second generation bioethanol, which is produced from lignocellulosic feedstock, is now being investigated. Production of second generation bioethanol involves pre-treatment and hydrolysis of lignocellulosic biomass to sugar monomers containing, amongst others, d-glucose and D-xylose. Intrinsically, S. cerevisiae strains lack the ability to ferment pentose sugars and genetic engineering of S. cerevisiae to inculcate the ability to ferment pentose sugars is ongoing to develop recombinant strains with the required stability and robustness for commercial second generation bioethanol production. Furthermore, pre-treatment of these lignocellulosic wastes leads to the release of inhibitory compounds which adversely affect the growth and fermentation by S. cerevisae. S. cerevisiae also lacks the ability to grow at high temperatures which favour Simultaneous Saccharification and Fermentation of substrates to bioethanol. There is, therefore, a need for robust yeast species which can co-ferment hexose and pentose sugars and can tolerate high temperatures and the inhibitory substances produced during pre-treatment and hydrolysis of lignocellulosic materials. Non-conventional yeast strains are potential solutions to these problems due to their abilities to ferment both hexose and pentose sugars, and tolerate high temperature and stress conditions encountered during ethanol production from lignocellulosic hydrolysate. This review highlights the limitations of the conventional yeast species and the potentials of non-conventional yeast strains in commercialization of second generation bioethanol.

Abstract
Copper (Cu) pollution of agricultural land is a major threat to crop production. Exogenous chemical treatment is an easily accessible and rapid approach to remediate metal toxicity, including Cu toxicity in plants. We compared the effects of ascobin (ASC; ascorbic acid:citric acid at 2:1) and glutathione (GSH) in mitigation of Cu toxicity in rice. Plants subjected to Cu stress displayed growth inhibition and biomass reduction, which were connected to reduced levels of chlorophylls, RWC, total phenolic compounds, carotenoids and Mg2+ . Increased accumulation of ROS and malondialdehyde indicated oxidative stress in Cu-stressed plants. However, application of ASC or GSH minimized the inhibitory effects of Cu stress on rice plants by restricting Cu2+ uptake and improving mineral balance, chlorophyll content and RWC. Both ASC and GSH pretreatments reduced levels of ROS and malondialdehyde and improved activities of antioxidant enzymes, suggesting their roles in alleviating oxidative damage. A comparison on the effects of ASC and GSH under Cu stress revealed that ASC was more effective in restricting Cu2+ accumulation (69.5% by ASC and 57.1% by GSH), Ca2+ and Mg2+ homeostasis, protection of photosynthetic pigments and activation of antioxidant defence mechanisms [catalase (110.4%), ascorbate peroxidase (76.5%) and guaiacol peroxidase (39.0%) by ASC, and catalase (58.9%) and ascorbate peroxidase (59.9%) by GSH] in rice than GSH, eventually resulting in better protection of ASC-pretreated plants against Cu stress. In conclusion, although ASC and GSH differed in induction of stress protective mechanisms, both were effective in improving rice performance in response to Cu phytotoxicity.

Abstract
An infrared absorption spectroscopy study of the endohedral water molecule in a solid mixture of H2O@C60 and C60 was carried out at liquid helium temperature. From the evolution of the spectra during the ortho-para conversion process, the spectral lines were identified as para-H2O and ortho-H2O transitions. Eight vibrational transitions with rotational side peaks were observed in the mid-infrared: ω1, ω2, ω3, 2ω1, 2ω2, ω1 + ω3, ω2 + ω3, and 2ω2 + ω3. The vibrational frequencies ω2 and 2ω2 are lower by 1.6% and the rest by 2.4%, as compared to those of free H2O. A model consisting of a rovibrational Hamiltonian with the dipole and quadrupole moments of H2O interacting with the crystal field was used to fit the infrared absorption spectra. The electric quadrupole interaction with the crystal field lifts the degeneracy of the rotational levels. The finite amplitudes of the pure v1 and v2 vibrational transitions are consistent with the interaction of the water molecule dipole moment with a lattice-induced electric field. The permanent dipole moment of encapsulated H2O is found to be 0.50 ± 0.05 D as determined from the far-infrared rotational line intensities. The translational mode of the quantized center-of-mass motion of H2O in the molecular cage of C60 was observed at 110 cm-1 (13.6 meV).

Abstract
Daikenchuto (DKT), a Japanese Kampo medicine, had been reported to increase small intestinal blood flow after liver resection. The aim of this study was to evaluate the effects of early enteral feeding of DKT on portal venous flow and early bowel movement after living donor liver transplantation (LDLT) in an attempt to clarify whether these effects on bowel motility can prevent bacterial and/or fungal translocation. MATERIALS AND METHODS Our prospective study included the consecutive 16 LDLT recipients at Mie University Hospital between June 2006 and September 2009. Sixteen patients were divided into the 2 groups according to enteral feeding starting postoperative day (POD) 1: 8 patients in DKT (15 g/d) administration (DKT group, for 1 week) and 8 patients in tepid water administration (non-DKT group, for 1 week). Portal venous flow, portal venous pressure, presence of fungal infection (serum level of β-D-glucan and fungal polymerase chain reaction assay), time to first food intake, and time to first defecation were serially examined. RESULTS Portal venous flow (mean [SD] velocity) was significantly increased in DKT group compared with non-DKT group: 47.5 (12.9) vs 31.8 (15.4) (P = .04) on POD 1, 46.8 (11.5) vs 28.8 (12.5) (P = .03) on POD 3, and 42.3 (17.2) vs 25.2 (9.0) (P = .05) on POD 5. However, mean (SD) portal venous pressures did not significantly change between the 2 groups. Between the 2 groups (DKT vs non-DKT), the day of first oral intake was not significantly different: 6.9 (2.5) vs 11.3 (8.7) (P = .061), but the mean (SD) day of first defecation was significantly shorter in the DKT group: 3.9 (1.1) vs 5.5 (2.6) (P = .02). Although fungal polymerase chain reaction assay was not significantly different between the 2 groups (4 vs 4 positive cases), the mean (SD) serum levels of β-D-glucan were significantly lower in the DKT group than in the non-DKT group: 9.0 (7.4) vs 18.4 (15.9) pg/mL (P = .04). CONCLUSION Early enteral feeding of DKT after LDLT increased portal vein blood flow without increasing portal vein pressure and stimulated early bowel movement, which in turn might prevent fungal translocation.

Abstract
Isolated biliary leakage is difficult to manage, and afflicted patients often develop refractory fistula. The present case was a 43-year-old male donor whose wife developed acute fulminant liver failure. Computed tomography (CT) volumetry showed that the estimated remnant liver volume was only 394 mL (31%) if his right lobe would be harvested. Since remnant liver volume was marginal, our proposed cut line for the right hepatectomy was set in order to preserve branches of the middle hepatic vein draining segments 4b+8 and 5. Right hepatectomy was performed, but on postoperative day 14, the donor developed fever and right back pain, and enhanced CT showed a 6 cm intra-abdominal abscess at the site of cutting, and we diagnosed it as an isolated biliary fistula since the isolated segment 5/8 was receiving arterial blood supply and exhibiting regrowth. A transabdominal abscess drainage was performed, after which the patient lost 30 to 50 mL of bile juice per day in drainage until 2 months after the drainage procedure. Ethanol injection, acetic acid injection, and transarterial or portal embolization for the isolated liver were proposed, but these all were impossible to carry out because there were no accessible routes. Thus, re-abscess drainage with a 7-French drainage catheter was performed through the isolated liver on postoperative day 53, and the isolated functional liver was punctured to induce liver atrophy. After this drainage, the isolated liver started to shrink and bile output had been stopped. In conclusion, our punctured-liver drainage could be effective for the treatment of isolated biliary fistula, allowing physicians to avoid an invasive additional liver resection or other invasive percutaneous approach using chemical reagents.

Abstract
Cellular responses to the transforming growth factor beta (TGFbeta) ligand, including inhibition of cell proliferation, are mediated by a heteromeric receptor complex composed of TGFbeta types I and II receptors (TbetaR-I and TbetaR-II). Loss of responsiveness to TGFbeta, attributed to inactivation of the TbetaR complex, has been implicated in the development of tumors in a number of human epithelial and lymphoid tissues. To gain a better understanding of TGFbeta signal transduction pathways in endometrial carcinogenesis, we have investigated the role of the TbetaR complex by evaluating the TbetaR-I and TbetaR-II genes for mutations throughout the entire coding region in human sporadic endometrial tumors. Using reverse transcription-PCR, "Cold" single-strand conformation polymorphism analysis, and direct DNA sequencing, it was found that 1 of 39 (2.6%) and 7 of 42 samples (17%) contained code-altering changes in the kinase domain of TbetaR-I and TbetaR-II, respectively. In 7betaR-I, a 3-bp deletion was found resulting in replacement of Arg and Glu at codon 237 and 238 by Lys. With TbetaR-II, mutations were found in the kinase, the extracellular, and the C-terminal domains. No frameshift mutations were detected; however, a silent population polymorphism (AAC-->AAT at codon 389) in TbetaR-II was found in 19 of 42 (44%) tumor samples. These results suggest that alteration in TbetaR-II, but not TbetaR-I, has an important role in the development of endometrial carcinoma.

Abstract
BACKGROUND There are several reports regarding total hip arthroplasty (THA) after a previous pelvic osteotomy (PO). However, to our knowledge, until now there has been no formal systematic review and meta-analysis published to summarize the clinical results of THA after a previous PO. Therefore, we conducted a systematic review and meta-analysis of results of THA after a previous PO. We focus on these questions as follows: does a previous PO affect the results of subsequent THA, such as clinical outcomes, operative time, operative blood loss, and radiological parameters. METHODS Using PubMed, Web of Science, and Cochrane Library, we searched for relevant original papers. The pooling of data was performed using RevMan software (version 5.3, Cochrane Collaboration, Oxford, UK). A p-value<0.05 was judged as significant. Standardized mean differences (SMD) were calculated for continuous data with a 95% confidence interval (CI) was reported. Statistical heterogeneity was assessed based on I2 using standard χ2 test. When I2>50%, significant heterogeneity was assumed and a random-effects model was applied for the meta-analysis. A fixed-effects model was applied in the absence of significant heterogeneity. RESULTS Eleven studies were included in this meta-analysis. The pooled results indicated that there was no significant difference in postoperative Merle D'Aubigne-Postel score (I2=0%, SMD=-0.15, 95% CI: -0.36 to 0.06, p=0.17), postoperative Harris hip score (I2=60%, SMD=-0.23, 95% CI: -0.50 to 0.05, p=0.10), operative time (I2=86%, SMD=0.37, 95% CI: -0.09 to 0.82, p=0.11), operative blood loss (I2=82%, SMD=0.23, 95% CI: -0.17 to 0.63, p=0.25), and cup abduction angle (I2=43%, SMD=-0.08, 95% CI: -0.25 to 0.09, p=0.38) between THA with and without a previous PO. However, cup anteversion angle of THA with a previous PO was significantly smaller than that of without a previous PO (I2=77%, SMD=-0.63, 95% CI: -1.13 to -0.13, p=0.01). CONCLUSION Systematic review and meta-analysis of results of THA after a previous PO was performed. A previous PO did not affect the results of subsequent THA, except for cup anteversion. Because of the low quality evidence currently available, high-quality randomized controlled trials are required. LEVEL OF EVIDENCE Level III, meta-analysis of case-control studies.

Abstract
BACKGROUND We compared achievement rate of sufficient tacrolimus blood concentration in the early postoperative period and incidence of acute cellular rejection within 1 month after living donor liver transplantation (LDLT) between tacrolimus intravenous (IV) and oral administration groups. METHODS From October 2005 to November 2016, 61 LDLT patients administered tacrolimus, who could be genotyped for CYP3A5*3 and *1, were chosen from the electronic record database. The patients were then divided into the 2 groups (an IV group [n = 38] and an oral group [n = 23]). We defined patients with 1*1 or *1*3 as expressors and those with *3*3 as nonexpressors. Sufficient trough level tacrolimus blood concentration on postoperative day (POD) 3 was defined as 10-20 ng/mL. RESULTS Comparable concentrations were seen between the 2 groups, with mean blood concentration 13.7 ± 8.5 ng/mL in the oral group and 15.2 ± 4.3 ng/mL in the IV group. Achievement rate of sufficient tacrolimus concentration on POD 3 was significantly higher in the IV group than in oral group: 97% (37 of 38) vs 65% (15 of 23), respectively (P = .001). When we focused on achievement rate in the oral group according to CYP3A5 polymorphism, the frequency of expressors (17%) was significantly lower than that of nonexpressors (82%) (P = .016). However, in the IV group this negative influence was totally eliminated, resulting in high achievement rates regardless of CYP3A5 polymorphism. In terms of incidence of acute cellular rejection, there was no significant difference between the 2 groups (IV 32% vs oral 17%, P = .250). CONCLUSION IV administration of tacrolimus allowed us to obtain more stable control of blood concentration regardless of CYP3A5 genotype.

Abstract
The cause of pleural effusion remains uncertain in approximately 15% of patients despite exhaustive evaluation. As recently described immunoglobulin (Ig)G4-related disease is a fibroinflammatory disorder that can affect various organs, including the lungs, we investigate whether idiopathic pleural effusion includes IgG4-associated etiology. Between 2000 and 2012, we collected 830 pleural fluid samples and reviewed 35 patients with pleural effusions undiagnosed after pleural biopsy at Yamaguchi-Ube Medical Center. Importantly, IgG4 immunostaining revealed infiltration of IgG4-positive plasma cells in the pleura of 12 patients (34%, IgG4+ group). The median effusion IgG4 level was 41 mg/dl in the IgG4+ group and 27 mg/dl in the IgG4- group (P < 0·01). The light and heavy chains of effusion IgG4 antibodies of patients in the IgG4+ group were heterogeneous by two-dimensional electrophoresis, indicating the absence of clonality of the IgG4 antibodies. Interestingly, the κ light chains were more heterogeneous than the λ light chains. The measurement of the κ and λ free light chain (FLC) levels in the pleural fluids showed significantly different κ FLC levels (median: 28·0 versus 9·1 mg/dl, P < 0·01) and κ/λ ratios (median: 2·0 versus 1·2, P < 0·001) between the IgG4+ and IgG4- groups. Furthermore, the κ/λ ratios were correlated with the IgG4+ /IgG+ plasma cell ratios in the pleura of the IgG4+ group. Taken together, these results demonstrate the involvement of IgG4 in certain idiopathic pleural effusions and provide insights into the diagnosis, pathogenesis and therapeutic opportunities of IgG4-associated pleural effusion.

Abstract
We report on the heterogeneous nucleation of catalyst-free InAs nanowires on Si(111) substrates by chemical beam epitaxy. We show that nanowire nucleation is enhanced by sputtering the silicon substrate with energetic particles. We argue that particle bombardment introduces lattice defects on the silicon surface that serve as preferential nucleation sites. The formation of these nucleation sites can be controlled by the sputtering parameters, allowing the control of nanowire density in a wide range. Nanowire nucleation is accompanied by unwanted parasitic islands, but careful choice of annealing and growth temperature allows us to strongly reduce the relative density of these islands and to realize samples with high nanowire yield.

Abstract
OBJECTIVE The goal of this study was to evaluate whether pretransplant serum hyaluronic acid (HA) levels can predict outcomes after adult-to-adult living donor liver transplantation (LDLT). METHODS In study I, 21 patients who underwent LDLT (March 2002-February 2004) were divided into 2 groups: the H-I group (HA ≥500 ng/mL; n = 12) and the L-I group (HA <500 ng/mL; n = 9). The influence of pretransplantation HA levels on short-term surgical outcome was investigated. In study II, 77 LDLT patients (May 2004-December 2014) were also divided into 2 groups: the H-II group (HA ≥500 ng/mL; n = 40) and the L-II group (HA <500 ng/mL; n = 37). We compared long-term survival and investigated prognostic factors. RESULTS In study I, HA levels significantly decreased after LDLT, and those in the H-I group were significantly higher compared with the L-I group at 1, 3, 5, and 7 days after LDLT. There were significant differences in postoperative peak total bilirubin levels (H-I vs L-I, 17.2 vs 6.2 mg/dL; P = .013), peak ascitic fluid volume (1327 vs 697 mL/d; P = .005), and the hepatocyte growth factor levels at 3 days after LDLT (1879 vs 1092 pg/mL; P = .03). In study II, the 1- and 5-year survival rates were significantly lower in the H-II group than in the L-II group (H-II vs L-II, 65.0% and 48.5% vs 86.5% and 80.8%; P = .004). In multivariate analysis, significant prognostic factors were preoperative HA ≥500 ng/mL (P = .004) and graft to recipient body weight ratio <0.8 (P = .042). CONCLUSIONS Preoperative HA level can be a prognostic risk factor. Patients with high HA levels are vulnerable and should be carefully managed after LDLT.

Abstract
INTRODUCTION For the patients undergoing liver transplantation for hepatitis B virus (HBV)-related diseases, hepatitis B immunoglobulin (HBIG) should be administered to prevent reinfection. Because HBIG is highly expensive and a blood product, an alternative strategy using HBV vaccination has been made in an attempt to discontinue use of HBIG. The aim of this study was to evaluate the impact of long-term HBV vaccination for discontinuation of HBIG, paying attention to the status of active immunization using T-cell proliferation assay. PATIENTS AND METHODS Among the 144 recipients who underwent liver transplantation in our hospital, 16 had HBV-related liver diseases; the 14 patients who had received vaccination were subjects in our study. To evaluate the status of active immunization, T-cell proliferation was examined by counting the number of T cells after adding HBV vaccine to the culture supernatant of T cells, and tumor necrosis factor α and interferon γ were measured in the culture supernatant. RESULTS The ratio of male/female was 13/1 (median age: 55 years; range: 37 years to 67 years). The median follow-up time was 102 months (range: approximately 14 months to 148 months). All 14 patients were free of HBV recurrence. HBIG-free status could be achieved in 9 patients (64.3%) during the treatment period for more than 50 months after beginning of HBV vaccination, of whom 5 (35.7%) became HBV vaccine-free. T-cell proliferation was confirmed by fact that the stimulation index ranged from 2.34 to 5.2 in the patients who were HBIG-free. CONCLUSION Long-term HBV vaccination after LT is a useful and effective treatment in preventing HBV recurrence, allowing the discontinuation of HBIG treatment.

Abstract
BACKGROUND Appropriate donor-recipient match has not been explored well in living-donor liver transplantation (LDLT) unlike deceased-donor liver transplantation. In this study, we evaluate the donor-recipient match using D-MELD (donor age × recipient Modified for End-stage Liver Disease [MELD] score) as a predictor of surgical outcomes in LDLT, paying attention to graft size and hepatitis C virus (HCV) status. PATIENT AND METHODS The 120 consecutive recipients who received adult-to-adult LDLT from March 2002 to December 2014 were divided into the two groups according to D-MELD score: D-MELD <1000 (low-D-MELD: n = 101) and D-MELD ≥1000 (high-D-MELD: n = 19). RESULTS The 90-day mortality rate was significantly higher in the high-DM group than in low-DM group: 36.8% versus 14.9% (P = .046). In the HCV-positive recipients, the 90-day mortality rate was significantly higher in high-DM group (n = 6) than in low-DM group (n = 37): 66.7% versus 13.5% (P = .012), and the 3-year survival rate was significantly lower in high-DM group than in the low-DM group: 33.3% versus 56.8% (P = .01). In the recipients with left graft, the 90-day mortality rate was significantly higher in the high-DM group (n = 8) than in the low-DM group (n = 41): 50% versus 14.6% (P = .044), and total bilirubin level on postoperative day 14 was significantly higher in the high-DM group than in the low-DM group: 17.4 mg/dL versus 9.2 mg/dL (P = .018). CONCLUSIONS It was clarified that D-MELD could predict early and long-term surgical outcomes in the recipients who were HCV-positive and who had smaller grafts.

Abstract
BACKGROUND Late renal dysfunction (LRD) is known to be one of the most important complications to affect long-term outcome after living-donor liver transplantation (LDLT). The relationship between angiotensin-converting enzyme insertion (I)/deletion (D) gene polymorphism and renal function after LDLT are still unknown. The aim of this study was to elucidate the risk factors for LRD after LDLT, focusing on ACE gene polymorphism. MATERIALS AND METHODS Among the 94 recipients who underwent adult-to-adult LDLT between March 2002 and September 2009, the total number of subjects who survived more than 1 year after LDLT and in whom angiotensin-converting enzyme genotype could be measured was 64. LRD was defined as estimated glomerular filtration rate level less than 60 mL/min/1.73 m(2) at any point after 1 year from undergoing LDLT. RESULTS LRD was found in 24 patients (37.5%). The incidence of LRD was significantly higher in D/D type than in I/I or I/D type: 85.7% (6/7) vs. 42.1% (8/19), 35.7% (10/38) (P = .010). Preoperative estimated glomerular filtration rate was significantly lower in D/D type than in I/I, I/D types, and postoperatively they were significantly lower in D/D type at 2, 3, and 4 years after LDLT. By multivariate analysis, age and hypertension were the independent risk factors for LRD. The 10-year survival rate was much lower in the recipients with LRD than in those without LRD at 66.7% versus 87.5%, respectively (P = .053). CONCLUSION In conclusion, age and hypertension were determined as significant independent risk factors for LRD after adult-to-adult LDLT, and the recipients with D/D genotype should be strictly cared for the development of LRD.

Abstract
BACKGROUND We report a rare case of 10-month-old female who underwent living donor liver transplantation (LDLT) for syndromic biliary atresia with preduodenal portal vein (PV) and its severe stricture owing to the previous Kasai portoenterostomy. Because we successfully performed "left at right liver transplantation (LAR-LT) and graft rerotation" in this case, we are present tips and pitfalls for this operation. METHODS Preoperative computed tomography scan showed that her preduodenal PV was stenotic from the confluence of the superior mesenteric vein and splenic vein to hepatic hilum, which made us consider the necessity of ≥3 cm interposition vein graft to complete a safe PV anastomosis. To reduce a gap between donor and recipient's PV, we decided to put a left lateral section graft at the right subphrenic space called left-at-right liver transplantation. Thus, LDLT was performed with an identical lateral sectional graft from her father. After total hepatectomy, we implanted a graft in her right subphrenic space, and anastomosed the donor left hepatic vein to her inferior vena cava. Then, we anastomosed an interposition graft harvested from her left internal carotid vein to her PV. RESULTS Even after reflowing PV flow, because the duodenum compressed the interposition vein graft, PV flows were totally insufficient. Therefore, we flipped a liver graft 180° from right to left upper abdominal cavity, which could reduce the gap between PVs and acceptable PV flow was obtained. CONCLUSIONS In the present case, LAR-LT could reduce the distance of PVs. In addition, our rerotation method could be useful to alleviate tension on the PV anastomosis caused by preduodenal PV.

Abstract
Methyl jasmonate (MeJA) and abscisic acid (ABA) signalling cascades share several signalling components in guard cells. We previously showed that two guard cell-preferential mitogen-activated protein kinases (MAPKs), MPK9 and MPK12, positively regulate ABA signalling in Arabidopsis thaliana. In this study, we examined whether these two MAP kinases function in MeJA signalling using genetic mutants for MPK9 and MPK12 combined with a pharmacological approach. MeJA induced stomatal closure in mpk9-1 and mpk12-1 single mutants as well as wild-type plants, but not in mpk9-1 mpk12-1 double mutants. Consistently, the MAPKK inhibitor PD98059 inhibited the MeJA-induced stomatal closure in wild-type plants. MeJA elicited reactive oxygen species (ROS) production and cytosolic alkalisation in guard cells of the mpk9-1, mpk12-1 and mpk9-1 mpk12-1 mutants, as well in wild-type plants. Furthermore, MeJA triggered elevation of cytosolic Ca(2+) concentration ([Ca(2+)]cyt ) in the mpk9-1 mpk12-1 double mutant as well as wild-type plants. Activation of S-type anion channels by MeJA was impaired in mpk9-1 mpk12-1. Together, these results indicate that MPK9 and MPK12 function upstream of S-type anion channel activation and downstream of ROS production, cytosolic alkalisation and [Ca(2+)]cyt elevation in guard cell MeJA signalling, suggesting that MPK9 and MPK12 are key regulators mediating both ABA and MeJA signalling in guard cells.

Abstract
BACKGROUND Biliary complications remain the leading cause of postoperative complications after living-donor liver transplantation (LDLT) in patients undergoing duct-to-duct choledochocholedochostomy. The aim of this study was to analyze the causes of these complications. METHODS One hundred eight patients who underwent LDLT with duct-to-duct biliary reconstruction at Mie University Hospital were enrolled in this study. The mean follow-up time was 58.4 months (range, 3-132). The most recent 18 donors underwent indocyanine green (ICG) fluorescence cholangiography for donor hepatectomy. The development of biliary complications was retrospectively analyzed. Biliary complications were defined as needing endoscopic or radiologic treatment. RESULTS Biliary leakages and strictures occurred in 6 (5.6%) and 15 (13.9%) of the recipients, respectively, and 3 donors (2.7%) experienced biliary leakage. However, since the introduction of ICG fluorescence cholangiography, we have not encountered any biliary complications in either donors or recipients. Biliary leakage was an independent risk factor for the development of biliary stricture (P = .013). Twelve (80%) of the 15 recipients with biliary stricture had successful nonoperative endoscopic or radiologic management, and 3 patients underwent surgical repair with hepaticojejunosotomy. CONCLUSIONS Biliary leakage was an independent factor for biliary stricture. ICG fluorescence cholangiography might be helpful to reduce biliary complications after LDLT in both donors and recipients.

Abstract
Methyl jasmonate (MeJA) signalling shares several signal components with abscisic acid (ABA) signalling in guard cells. Cyclic adenosine 5'-diphosphoribose (cADPR) and cyclic guanosine 3',5'-monophosphate (cGMP) are second messengers in ABA-induced stomatal closure. In order to clarify involvement of cADPR and cGMP in MeJA-induced stomatal closure in Arabidopsis thaliana (Col-0), we investigated effects of an inhibitor of cADPR synthesis, nicotinamide (NA), and an inhibitor of cGMP synthesis, LY83583 (LY, 6-anilino-5,8-quinolinedione), on MeJA-induced stomatal closure. Treatment with NA and LY inhibited MeJA-induced stomatal closure. NA inhibited MeJA-induced reactive oxygen species (ROS) accumulation and nitric oxide (NO) production in guard cells. NA and LY suppressed transient elevations elicited by MeJA in cytosolic free Ca(2+) concentration ([Ca(2+)]cyt) in guard cells. These results suggest that cADPR and cGMP positively function in [Ca(2+)]cyt elevation in MeJA-induced stomatal closure, are signalling components shared with ABA-induced stomatal closure in Arabidopsis, and that cADPR is required for MeJA-induced ROS accumulation and NO production in Arabidopsis guard cells.
