Abstract
Using the fusion-evaporation reaction ^{106}Cd(^{58}Ni,4n)^{160}Os and the gas-filled recoil separator SHANS, two new isotopes _{76}^{160}Os and _{74}^{156}W have been identified. The α decay of ^{160}Os, measured with an α-particle energy of 7080(26) keV and a half-life of 201_{-37}^{+58} μs, is assigned to originate from the ground state. The daughter nucleus ^{156}W is a β^{+} emitter with a half-life of 291_{-61}^{+86} ms. The newly measured α-decay data allow us to derive α-decay reduced widths (δ^{2}) for the N=84 isotones up to osmium (Z=76), which are found to decrease with increasing atomic number above Z=68. The reduction of δ^{2} is interpreted as evidence for the strengthening of the N=82 shell closure toward the proton drip line, supported by the increase of the neutron-shell gaps predicted in theoretical models.

Abstract
INTRODUCTION Splanchnic arterial aneurysms are a rare but potentially lethal disease with a mortality rate of more than 10% after rupture. Endovascular therapy is the first-line treatment for splanchnic aneurysms. However, appropriate management for splanchnic aneurysms after failed endovascular therapy remained inconclusive. MATERIALS AND METHODS A retrospective review was performed for consecutive patients (from 2019 to 2022) who underwent salvage surgeries for splanchnic artery aneurysms following failed endovascular therapy. We defined failed endovascular therapy as technical infeasibility to apply endovascular therapy, incomplete exclusion of the aneurysm, or the incomplete resolution of preoperative aneurysm-associated complications. Salvage operations included aneurysmectomy with vascular reconstruction and partial aneurysmectomy with directly closing of bleeders from the intraluminal space of the aneurysms. RESULTS Seventy-three patients received endovascular therapies for splanchnic aneurysms, and 13 failed endovascular trials. We performed salvage surgeries for five patients and enrolled them in this study, including four false aneurysms of the celiac or superior mesenteric arteries and a true aneurysm of the common hepatic artery. The causes of failed endovascular therapy included coil migration, insufficient space for safely deploying the covered stent, a persistent mass effect from the post-embolized aneurysm, or infeasibility for catheter cannulation. The mean hospital stay was nine days (mean±SD, 8.8±1.6 d), with no one suffering 90-day surgical morbidity and mortality, and all patients getting symptoms improvement. During the follow-up period (mean±SD, 24±10 mo), one patient suffered a small residual asymptomatic celiac artery aneurysm (8 mm in diameter) and was treated conservatively due to underlying liver cirrhosis. CONCLUSION Surgical management is a feasible, effective, and safe alternative for splanchnic aneurysms after failed endovascular therapy.

Abstract
Objective: To evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI) with the novel Prizvalve® system in treating severe aortic stenosis. Methods: This is a single-center, prospective, single-arm, observational study. A total of 11 patients with severe aortic stenosis with high risk or inappropriate for conventional surgical aortic valve replacement (SAVR) were included, and TAVI was achieved with the Prizvalve® system between March 2021 and May 2021 in West China Hospital. Transthoracic echocardiography (TTE) was performed immediately after prosthesis implantation to evaluate mean transaortic gradient and maximal transaortic velocity. The device success rate was calculated, which was defined as (1) the device being delivered via the access, deployed, implanted and withdrawn, (2) mean transaortic gradient<20 mmHg (1 mmHg=0.133 kPa) or a maximal transaortic velocity<3 m/s post TAVI, and without severe aortic regurgitation or paravalvular leak post TAVI. TTE was performed at 30 days after the surgery, and all-cause mortality as well as the major cardiovascular adverse events (including acute myocardial infarction, disabling hemorrhagic or ischemic stroke) up to 30 days post TAVI were analyzed. Results: The age of 11 included patients were (78.1±6.3) years, with 8 males. A total of 10 patients were with NYHA functional class Ⅲ or Ⅳ. Devices were delivered via the access, deployed, implanted and withdrawn successfully in all patients. Post-implant mean transaortic gradient was (7.55±4.08) mmHg and maximal transaortic velocity was (1.78±0.44) m/s, and both decreased significantly as compared to baseline levels (both P<0.05). No severe aortic regurgitation or paravalvular leak was observed post TAVI. Device success was achieved in all the 11 patients. No patient died or experienced major cardiovascular adverse events up to 30 days post TAVI. Mean transaortic gradient was (9.45±5.07) mmHg and maximal transaortic velocity was (2.05±0.42) m/s at 30 days post TAVI, which were similar as the values measured immediately post TAVI (both P>0.05). Conclusions: TAVI with the Prizvalve® system is a feasible and relatively safe procedure for patients with severe aortic stenosis and at high risk or inappropriate for SAVR. Further clinical studies could be launched to obtain more clinical experience with Prizvalve® system.

Abstract
A new α-emitting isotope ^{214}U, produced by the fusion-evaporation reaction ^{182}W(^{36}Ar,4n)^{214}U, was identified by employing the gas-filled recoil separator SHANS and the recoil-α correlation technique. More precise α-decay properties of even-even nuclei ^{216,218}U were also measured in the reactions of ^{40}Ar, ^{40}Ca beams with ^{180,182,184}W targets. By combining the experimental data, improved α-decay reduced widths δ^{2} for the even-even Po-Pu nuclei in the vicinity of the magic neutron number N=126 are deduced. Their systematic trends are discussed in terms of the N_{p}N_{n} scheme in order to study the influence of proton-neutron interaction on α decay in this region of nuclei. It is strikingly found that the reduced widths of ^{214,216}U are significantly enhanced by a factor of two as compared with the N_{p}N_{n} systematics for the 84≤Z≤90 and N<126 even-even nuclei. The abnormal enhancement is interpreted by the strong monopole interaction between the valence protons and neutrons occupying the π1f_{7/2} and ν1f_{5/2} spin-orbit partner orbits, which is supported by the large-scale shell model calculation.

Abstract
BACKGROUND ABO-incompatible (ABO-i) living donor liver transplantation (LDLT) is a feasible alternative for donor liver allograft in emergency situations, especially in Asia, where deceased-donor organs remain scarce. The reported outcomes of ABO-i LDLT after optimal desensitization are comparable to those of ABO-compatible LDLT. In this retrospective study, we found improved outcomes after ABO-i LDLT with a low-dose rituximab in combination with double-filtration plasmapheresis (DFPP) and prophylactic antibiotic therapy. MATERIAL AND METHODS Between January 2006 and December 2018, a total of 65 recipients underwent ABO-i LDLT surgeries at our center. The study cohort consisted of 50 recipients (Era III) who underwent ABO-i LDLT using the recently updated desensitization protocol, which included rituximab 200 mg intravenous injection once a week prior to LDLT, 4 sessions of DFPP in all patients, and prophylactic antibiotics for 3 months. RESULTS The 3-year overall survival rate achieved in ABO-i LDLT patients was 72.7% (66.6% for Era I and 33.3% for Era II patients). In the study population, 11 patients developed complications due to infection. Five of these patients (10%) died due to overwhelming sepsis. Four patients (8%) were diagnosed with multiple strictures and diffusely scattered dilatation of intrahepatic bile ducts on computed tomography, without vascular complications. Three of them had evidence of antibody-mediated rejection (AMR). CONCLUSIONS Our experience shows that the ABO-i LDLT protocol of lowered rituximab combined with pre-transplant sessions of plasmapheresis and a quadruple immunosuppressive regimen can be effective in chronic liver failure patients with clinical urgency in the absence of an ABO-compatible donor. Fast-tracking the use of ABO-i LDLT is feasible in patients with an acute liver failure (ALF) and can safely increase the donor liver pool, with an acceptable outcome.

Abstract
BACKGROUND Sorafenib has been shown to prolong the progression free survival (PFS) of advanced radioiodine (RAI) refractory differentiated thyroid cancer (DTC) and has been approved by the FDA as the result of the phase III DECISION trial. Sorafenib has been reimbursed for the treatment of RAI refractory DTC in Taiwan since Jan 2017. High percentage of adverse events (AE) was noted in DECISION trial. We conducted a study to show the real-world experience of sorafenib in Taiwan. METHODS We retrospectively collected the clinical data, including dose, AE, and PFS of sorafenib, of the DTC patients who received sorafenib treatment in National Cheng Kung University Hospital and China Medical University Hospital by chart review from 2012 to 2018. RESULTS Thirty-six advanced DTC patients with progression were included in this study. The starting dose of sorafenib in most patients was 200 mg twice daily and the mean daily maintenance dose was 433 mg. Five patients had partial response (13.9%) and 28 patients had stable disease (77.8%). The median PFS was 17.3 months (95% confidence interval: 11.9-33.6 months). Daily maintenance dose ≥ 600 mg was associated with better PFS (median PFS, not reached). The most common toxicity of sorafenib was hand foot skin reaction (69%), followed by diarrhea (42%), and skin rash (33%). Most of the toxicities were grade I/II. CONCLUSION Higher maintenance dose of sorafenib is associated with longer PFS while starting from half dose is feasible to minimize the incidence of high grade toxicities in the real-world use of sorafenib.

Abstract
AIM To investigate the association between adiponectin (ADIPOQ) genotypes and colorectal cancer (CRC) risk among Taiwanese. MATERIALS AND METHODS Polymerase chain reaction-restriction fragment length polymorphism was adopted to identify ADIPOQ rs266729, rs2241766 and rs1501299 genotypes among 362 CRC patients and 362 healthy controls. RESULTS ADIPOQ rs266729 GG genotype (p=0.0075) and G allele (p=0.0061) are associated with a significantly increased CRC risk. There is no differential distribution of rs2241766 and rs1501299 genotypes. As for the gene-lifestyle interaction, there are obvious joint effects of rs266729 genotype on the CRC risk among non-smoker, non-alcohol drinker, while not on smoker or non-drinker subgroups. No significant correlation was observed between rs266729 genotypic distributions and age, gender, tumor size, location or metastasis status. Interestingly, a correlation of rs266729 genotype and larger BMI on CRC risk was found. CONCLUSION G allele at ADIPOQ rs266729 may serve as a determiner for CRC risk, especially for those with BMI ≥24.

Abstract
OBJECTIVES In the Asian population, patterns and risk factors for de novo malignancies after solid-organ transplant are not well understood. MATERIALS AND METHODS Insurance claims from Taiwan's National Health Institute Research Database from 1997 to 2011 revealed 687 deceased-donor heart transplant recipients, 5038 kidney transplant recipients (50% living related-donor, 50% deceased-donor transplants), and 2127 liver transplant recipients (mainly living related-donor transplants, 30% deceased-donor transplants). During the follow-up period, rates of malignancy incidence were calculated with standardization based on national age, sex, and year-specific incidence. We used multivariate regression analyses to determine risk factors of posttransplant de novo malignancies. RESULTS Compared with the general population, several de novo cancers were more common posttransplant (P < .05): lung cancer (2.6-fold), non-melanoma skin cancer (5.8-fold), and non-Hodgkin lymphoma (5.4-fold) in heart recipients; transitional cell carcinoma (31.4-fold), renal cell carcinoma (37.3-fold), and non-Hodgkin lymphoma (3.6-fold) in kidney recipients; and gastric cancer (3.0-fold) and lymphatic-hematopoietic malignancy (4.5-fold) in liver recipients. Independent risk factors for posttransplant malignancy in kidney transplant recipients were increased age, female, hepatitis B virus, and mycophenolate use (adjusted hazard ratio 1.5; 95% confidence interval, 1.2-1.8; P < .001). In liver transplant recipients, old age was an independent risk factor. Kidney transplant recipients without diabetes or hypertension had higher risk of transitional cell carcinoma (adjusted hazard ratio 3.0; 95% confidence interval, 2.1-4.4; P < .001) and renal cell carcinoma (adjusted hazard ratio 1.9; 95% confidence interval, 1.1-3.3; P < .05). CONCLUSIONS Regional endemic epidemiologic factors play significant roles in the development of de novo cancers, particularly in kidney transplant recipients due to causes of renal failure other than diabetes and hypertension. Each regional organ transplant program should tailor and establish its surveillance protocol based on epidemiologic data. However, the type and intensity of surveillance require further and long-term investigations in this patient cohort.

Abstract
BACKGROUND To report experience of laparoscopic liver resection (LLR) in one center. METHODS We retrospectively reviewed 436 consecutive LLRs in 411 patients between December 2010 and December 2016. On the basis of the 2008 Louisville Statement, we divided the 436 cases into two groups: Simple Group (n = 203) and Difficult Group (n = 233). RESULTS The indications were HCC (n = 194), colorectal cancer liver metastasis (n = 156), benign tumors (n = 62), hepatolithiasis (n = 2), and other malignant lesions (n = 22). The median tumor size was 24 mm (range 3 to 130). Procedures of LLR included wedge resection (n = 230), one segmentectomy (n = 8), two segmentectomies (n = 12), left lateral sectionectomy (n = 75), right hepatectomy (n = 52), left hepatectomy (n = 31), extended right hepatectomy (n = 2), extended left hepatectomy (n = 5), central bisectionectomy (n = 3), right posterior sectionectomy (n = 12), and right anterior sectionectomy (n = 6). The median operative time was 228 min (range 9-843) and median blood loss was 150 ml (range 2-3500). Twenty-five cases required blood transfusion (5.7%). Conversion to open surgery was required in six cases (1.4%). The mean length of stay was 6.4 ± 2.9 days. Overall complication rate was 9.4% and major complication rate was 5%. One patient died of liver failure on the thirtieth postoperative day after a right hepatectomy. We had higher median blood loss (200 vs. 100 ml; p < 0.001), higher transfusion rate (8.2 vs. 2.9%; p = 0.020), longer median operative time (297 vs. 164 min; p < 0.001), higher conversion rate (2.6 vs. 0%; p = 0.021), higher complication rate (14.2 vs. 3.9%; p < 0.001), and longer mean postoperative hospital stay (6.8 ± 2.9 vs. 5.9 ± 3.0 days; p < 0.001) in the Difficult Group. CONCLUSIONS Laparoscopic liver resection is safe for selected patients in the Difficult Group. On the basis of the 2008 Louisville Statement, selection criteria of LLR are helpful to predict the difficulty of the operation and the postoperative outcomes of LLR.

Abstract
In a multicenter, open-label, study, 284 living-donor liver transplant patients were randomized at 30 ± 5 days posttransplant to start everolimus+reduced tacrolimus (EVR+rTAC) or continue standard tacrolimus (TAC Control). EVR+rTAC was non-inferior to TAC Control for the primary efficacy endpoint of treated BPAR, graft loss or death at 12 months posttransplant: difference -0.7% (90% CI -5.2%, 3.7%); P < .001 for non-inferiority. Treated BPAR occurred in 2.2% and 3.6% of patients, respectively. The key secondary endpoint, change in estimated glomerular filtration rate (eGFR) from randomization to month 12, achieved non-inferiority (P < .001 for non-inferiority), but not superiority and was similar between groups overall (mean -8.0 vs. -12.1 mL/min/1.73 m2 , P = .108), and in patients continuing randomized treatment (-8.0 vs. -13.3 mL/min/1.73 m2 , P = .046). In the EVR+rTAC and TAC control groups, study drug was discontinued in 15.5% and 17.6% of patients, adverse events with suspected relation to study drug occurred in 57.0% and 40.4%, and proteinuria ≥1 g/24 h in 9.3% and 0%, respectively. Everolimus did not negatively affect liver regeneration. At 12 months, hepatocellular recurrence was only seen in the standard TAC-treated patients (5/62; 8.1%). In conclusion, early introduction of EVR+rTAC was non-inferior to standard tacrolimus in terms of efficacy and renal function at 12 months, with hepatocellular carcinoma recurrence only in TAC Control patients.

Abstract
Objective: To explore age-based clinical and immune parameters in Henoch-Schönlein purpura (HSP) to determine clinically useful markers reflecting disease characteristic. Methods: A cohort of 502 patients with HSP were enrolled into this retrospective study to evaluate their clinical and immune data. Results: Majority HSP cases occurred at age ≤14 years and showed significant immune imbalances of ESR, CD3(+) cells, CD4(+) cells, CD3(-)CD16(+)CD56(+) cells, CD4(+)/CD8(+) cells, IgG, IgA, IgM, IgE, complements C3/C4 and ASO in the acute phase. Compared to patients aged >14 years, symptoms of joint were more frequent at disease onset in patients aged ≤14 years (20.8% vs 7.6%, χ(2)=13.547, P<0.001) , and involvement of digestive tract and joint were also more frequent (57.4% vs 33.8%, χ(2)=24.106, P<0.001; 55.9% vs 32.5%, χ(2)=23.768, P<0.001, respectively) , but not for involvement of kidney (21.4% vs 51.3%, χ(2)=42.440, P<0.001) . The patients aged ≤14 years had distinct immune state, reductions of CD3(+) cells, CD4(+) cells and IgG were more frequent than patients aged >14 years, also increase of ASO (33.1% vs 20.0%, χ(2)=6.656, P=0.010) , but not increase of IgA (2.6% vs 39.4%, χ(2)=15.582, P<0.001) . In addition, reduction of IgG and increase of IgE were positively associated with digestive tract involvement (P<0.001, P=0.001, respectively) , reduction of CD3(+)CD4(+) cells and normal IgM were positively associated with joint involvement (P=0.004, P=0.003, respectively) , increase of CD3(+)CD8(+) cells and normal CD3(+) cells were positively associated with kidney involvement (P=0.032, P=0.014, respectively) . Conclusion: HSP showed significant immune imbalance in the acute phase, patients between aged ≤14 and >14 years had distinct clinical and immune characteristic, and abnormal immune parameters were significantly associated with organ involvements.

Abstract
Background The prognosis of the patients of acute liver failure (ALF) with onset of hepatic coma is often dismal. ALF is a well-accepted indication for liver transplantation (LT) and has markedly improved the prognosis of these patients. However, its role in ALF patients with onset of hepatic coma has never been elucidated before. The aim of our study was to analyze the outcome in patients of ALF with hepatic coma who underwent LT. Material/Methods From January 2002 to December 2015, a total of 726 liver transplantations were done at China Medical University Hospital, Taiwan. The hospital database of 59 recipients that underwent LT for ALF was analyzed. Eleven ALF patients with the onset of hepatic coma (grade IV encephalopathy) requiring mechanical ventilatory support were retrospectively analyzed. The patients were sub-grouped in 2 groups depending on the timing of LT after the onset of hepatic coma: Group A had LT within 48 h of onset of coma (n=7) and Group B had LT after 48 h of onset of coma (n=4). Results The study cohort (group A and B) comprised 8 males and 3 females, with an average age of 39.63±13.95 years (range, 13 to 63). Ten patients received living donor liver transplantation (LDLT) and deceased donor liver transplantation (DDLT) was done in 1 recipient. All the patients in group A had complete neurological recovery and were extubated within 48 h after LT, whereas extubation was delayed for various reasons for group B patients. At a mean follow up of 36 months (range, 20 to 76 months), the overall survival of all the recipients (group A and B) was 72%. Three-year survival for Group A (n=7) was 85% and for Group B (n=4) it was 50%. There were no acute rejection episodes. Conclusions LT is an acceptable modality of treatment for patients of ALF with new onset of hepatic coma. Neurological recovery is expected in all patients if LT can be done within 48 h of onset of hepatic coma without increasing the risk of morbidity. Due to shortage of deceased donor organs in Asia, LDLT can be used proactively, with a success rate comparable to that of non-ALF patients undergoing LT.

Abstract
Backgrounds/Aims The protective effect of everolimus (EVR) in hepatocellular carcinoma (HCC) patients who receive liver transplantation in terms of reducing the recurrence has not been sufficiently investigated in clinical trials. In this second stage of our ongoing study, we intend to analyze the effects of EVR as an immunosuppressant, when it is started in the early phase after living donor liver transplantation (LDLT), on HCC recurrence in patients with HCC within the University of California at San Francisco (UCSF) criteria. Methods From January 2011 to June 2013, a total of 250 patients underwent LDLT for HCC at our institute. The patients with HCC within the UCSF criteria were included in the study and divided in two groups depending upon the postoperative immunosuppression. Group A: HCC patients that received EVR+TAC based immunosuppressive regimen (n=37). Group B: HCC patients that received standard TAC based immunosuppressive regimen without EVR (n=29). The target trough level for EVR was 3 to 5 ng/ml while for TAC it was 8–10 ng/ml. Results For group A patients, the mean trough level of the EVR was 3.47±1.53 ng/ml (range, 1.5–11.2) with a daily dose of 1.00±0.25 mg/day. For group A and B, the average TAC trough levels were 6.97±3.98 ng/ml (range, 2.50 to 11.28 ng/ml) and 6.93±2.58 (range, 2–16.30), respectively. The 1-year, 3-year and 4-year overall survival achieved for Group A patients was 94.95%, 86.48% and 86.48%, respectively while for Group B patients it was 82.75%, 68.96%, and 62.06%, respectively (p=0.0217). Conclusions EVR use in liver transplant recipients in the early stage after transplantation reduces the HCC recurrence rates in HCC patients within the UCSF criteria.

Abstract
BACKGROUND Rituximab is commonly used to reduce the agglutinin titer in ABO-incompatible liver transplant recipients. Although well-tolerated, rituximab infusion therapy may result in severe pulmonary adverse effects such as drug-induced pneumonitis, leading to acute respiratory distress syndrome (ARDS), which has a high mortality rate. Management of such rare cases in an ABO-incompatible patient has never been described before. Herein, we present successful use of extracorporeal membrane oxygenation (ECMO) support for rituximab-induced ARDS in an ABO-incompatible living donor liver transplantation (LDLT) recipient. CASE REPORT A 57-year-old man patient presented with acute-on-chronic hepatic failure. Due to worsening clinical condition and unavailability of a deceased donor organ, ABO-incompatible LDLT was considered. The patient received rituximab therapy and plasmapheresis 1 week before the transplantation to reduce the B cell count. However, he suddenly developed acute respiratory distress-like symptoms, with a chest X-ray suggesting organized pneumonia. Infectious etiology was excluded as evidenced from negative sputum and blood culture, which were repeated after 48 h. LDLT was performed and ECMO support was instituted in the immediate postoperative period due to worsening of the ARDS. The pulmonary signs improved, with a chest X-ray showing clear lung fields on the 5th postoperative day. The patient recovered well and was discharged with normal liver functions in the 4th postoperative month. CONCLUSIONS This is first reported experience of successful use of ECMO in an ABO-incompatible liver transplant recipient with rituximab-induced ARDS. This experience shows the feasibility and effectiveness of ECMO support in liver transplant recipients with poor respiratory functions.

Abstract
Background Our recent studies have highlighted the importance and safety of backtable venoplasty for middle hepatic vein (MHV) and inferior right hepatic veins (IRHV) reconstruction using expanded polytetrafluoroethylene (ePTFE) vascular grafts. In this study, we aim to analyze the complications associated with ePTFE graft use and discuss the management of the rare, but, potentially life threatening complications directly related to ePTFE conduits. Material/Methods From January 2012 to October 2015 a total of 397 patients underwent living donor liver transplantation (LDLT). The ePTFE vascular grafts were used during the backtable venoplasty for outflow reconstruction in 262 of the liver allografts. Recipients who developed ePTFE-related complications were analyzed. Results ePTFE-related complications developed in 1.52% (4/262) of the patients. One patient (0.38%) developed complete thrombosis with sepsis at 24 months post-transplantation and died due to multiorgan failure. Three patients (1.1%) developed graft migration into the second portion of the duodenum, without overt peritonitis. Surgical exploration and ePTFE graft removal was done in all the patients. One patient died due to overwhelming sepsis. Conclusions ePTFE graft migration into the duodenum causing perforation is a new set of complications that has been recently described in LDLT and can be treated effectively by surgical removal of the infected vascular graft and duodenal perforation closure. Despite of such complications, in our experience, ePTFE use in LDLT continues to have wide safety margin, with a complication rate of only 1.52%.

Abstract
The reconstruction of the hepatic artery (HA) is the most complex step in living donor liver transplantation (LDLT) because of the smaller diameter of the artery and the increased risk of HA-related complications. Because of the smaller diameter of the HA, many centers use a microsurgical technique with interrupted sutures for arterial anastomosis. The aim of our study was to retrospectively investigate the outcomes after HA reconstruction performed under magnifying loupes using the "parachute technique." From August 1, 2002 to August 31, 2016, LDLT was performed in 766 recipients. HA reconstruction for the initial 25 LDLT surgeries was performed using a microsurgery technique (era 1). From May 2007 until the end date, HA reconstruction was performed in 741 recipients by a "parachute technique" under surgical loupes (era 2). HA reconstruction was performed using surgical loupes in 737 adults (male:female, 526:211) and 4 pediatric patients (male:female, 3:1). The average diameter of the donor graft HA was 2.8 mm (range, 1-6.5 mm). The most notable factor in this era was the quick HA anastomosis procedure with a mean time of 10 ± 5 minutes (range, 5-30 minutes). In era 2, 9 (1.21%) patients developed hepatic artery thrombosis (HAT), whereas 2 patients developed nonthrombotic HA-related complications. Extra-anatomic HA reconstruction was performed in 14 patients due to either primary HA anastomosis failure or a poor caliber recipient HA. The use of magnifying surgical loupes to perform HA reconstruction is safe, feasible, and yields a low incidence of HA-related complications. The "parachute technique" for HA reconstruction can achieve a speedy reconstruction without increasing the risk of HAT. Liver Transplantation 23 887-898 2017 AASLD.

Abstract
BACKGROUND Liver allograft trauma resulting in subcapsular hematoma after living donor liver transplantation (LDLT), although rare, is a life-threatening condition and requires prompt management to avoid any catastrophe. Herein we describe our successful experience in dealing with liver allograft hematoma that developed in the post-operative period after LDLT. MATERIAL AND METHODS From January 2002 to May 2015, a total of 616 recipients underwent LDLT at our institute. The intra-operative and postoperative records of these patients were analyzed to study the cases of liver allograft hematoma. Four patients (n=4) who developed liver allograft subcapsular hematoma during the intra-operative and post-operative periods were included in study. The outcomes of these patients were studied after the administration of the medical, surgical, or combined modalities of treatment. RESULTS Out of 616 LDLT recipients, 4 (0.64%) developed subcapsular hematoma. Patients were managed by a stepwise approach: Initial non-operative management with transarterial embolization (if extravasation of the contrast was noticed during imaging studies) was performed (n=1). Three patients developed hemodynamic instability with signs of hematoma rupture and were successfully treated by surgical exploration. CONCLUSIONS Timely diagnosis and suitable management can successfully salvage a liver allograft even in the presence of massive subcapsular hematoma. Our emphasis is on perihepatic packing rather than open surgical drainage if exploration is required, which can achieve a 100% success rate.

Abstract
Background The influence of adjuvant chemotherapy on the survival of gastric adenocarcinoma patients in a stage-specific manner is controversial. Methods To further explore this topic, we retrospectively analyzed the impact of adjuvant chemotherapy on the clinical outcomes of 77 stage II and 117 stage III patients diagnosed between January 2008 and December 2012. Results All 194 patients underwent radical operation plus D2 dissection, and were followed a median time of 23.3 (range 0.4–80.2) months. Median patient age was 67.7 (range 33.9–97.5) years. Adjuvant chemotherapy prolonged the relapse-free survival [22.9 (95 % confidence interval 9.4–36.4) vs. 14.2 (95 % CI 8.6–19.8) months, P = 0.009] and overall survival [32.3 (95 % CI 22.6–42.0) vs. 13.4 (95 % CI 9.5–17.2) months, P < 0.001] for patients with stage III, but not stage II, disease. Higher overall survival from adjuvant chemotherapy in stage II patients with node involvement did not reach the level of statistical significance (P = 0.102). To reduce the selection bias, 142 patients aged <75 years were included in a subgroup analysis in which the benefit of adjuvant chemotherapy on relapse-free survival and overall survival were demonstrated for patients with stage III disease. Conclusions Adjuvant chemotherapy prolongs relapse-free and overall survival for patients with stage III gastric cancer in a real-world situation. Tailoring therapy based on different characteristics for patients with stage II gastric cancer may produce better outcomes.

Abstract
Graphene, whose absorbance is approximately independent of wavelength, allows broadband light–matter interactions with ultrafast responses. The interband optical absorption of graphene can be saturated readily under strong excitation, thereby enabling scientists to exploit the photonic properties of graphene to realize ultrafast lasers. The evanescent field interaction scheme of the propagating light with graphene covered on a D-shaped fibre or microfibre has been employed extensively because of the nonblocking configuration. Obviously, most of the fibre surface is unused in these techniques. Here, we exploit a graphene-clad microfibre (GCM) saturable absorber in a mode-locked fibre laser for the generation of ultrafast pulses. The proposed all-surface technique can guarantee a higher efficiency of light–graphene interactions than the aforementioned techniques. Our GCM-based saturable absorber can generate ultrafast optical pulses within 1.5 μm. This saturable absorber is compatible with current fibre lasers and has many merits such as low saturation intensities, ultrafast recovery times, and wide wavelength ranges. The proposed saturable absorber will pave the way for graphene-based wideband photonics.

Abstract
Outflow reconstruction in living donor liver transplantation (LDLT) is certainly difficult in limited retrohepatic space with using right liver grafts with venous anomalies. Venoplasty of the inferior right hepatic veins (IRHVs) and middle hepatic vein (MHV) reconstruction using synthetic grafts to form a common outflow channel or a second venocaval anastomosis are available options. We aim to compare outcomes of LDLT recipients who underwent outflow reconstruction with a "V-Plasty" technique and outcomes of patients who underwent a second venocaval anastomosis. Out of 325 recipients who underwent LDLT from March 2011 to September 2014, 45 received right liver allografts that were devoid of MHV with multiple draining IRHVs (2 or more). Group A (n = 16) comprised the recipients with outflow reconstruction with a V-Plasty, and group B (n = 29) included the recipients with a second venocaval anastomosis. Group A recipients (male:female, 10:6; median age, 50.5 years) had a mean Model for End-Stage Liver Disease score of 14.7, whereas for group B recipients (male:female, 20:9; median age, 52.0 years) it was 17.2. The mean IRHV diameter for group A and B grafts was 8.3 mm each. Mean warm ischemia time for group A was significantly lower (25.2 minutes) as compared to group B recipients (34.6 minutes) with P < 0.001. The 2-month patency rates of vascular grafts were 100% for group A recipients with no evidence of thrombosis. In conclusion, the V-Plasty technique of MHV and IRHV reconstruction to form a common outflow is a new concept that proves to be a safe and feasible alternative for second venocaval anastomosis.

Abstract
The reconstruction of the vascular outflow tract of partial liver grafts has received considerable attention in the past, especially in the setting of right liver grafts with undrained segments. Hepatic venous outflow reconstruction is an important factor for successful living donor liver transplantation outcome. However, in presence of undrained anterior sector and presence of multiple short hepatic veins that drain substantial portions of liver, outflow reconstruction without backtable venoplasty may lead to severe graft congestion and subsequent graft dysfunction. Various backtable venoplasty techniques in presence of multiple hepatic veins that can be used in either right- or left-lobe liver transplantation are devised to ensure a single, wide outflow channel. In this overview, various techniques to overcome the hepatic venous variations of liver allograft and outflow reconstruction are discussed.

Abstract
Malignant cell seeding in subcutaneous tissues along the needle track and/or percutaneous biliary drainage catheters is rare complication, but pose various technical issues in planning surgical treatment of such patients. If underlying primary hepatic malignancy can be treated, an aggressive resection of subcutaneous tissue bearing cancer cell with subsequent abdominal wall reconstruction has been sporadically reported. But, when hepatic resection is not possible due to underlying advanced cirrhosis, liver transplantation along with abdominal wall resection and subsequent reconstruction remains only feasible option. Herein, we describe our successful experience of living donor liver transplantation for hepatocellular carcinoma with full-thickness abdominal wall resection bearing the tumor seeding followed by reconstruction in single stage surgery.

Abstract
UNLABELLED About 1051 endophytic fungi were isolated from leaves, branches, barks and stems of Cephalotaxus hainanensis Li from four sites in Hainan, China. The fungi were identified as 21 genera by morphology and ITS sequences. One dominant species was Phomopsis quercella in Hainan Tropical Botanical Garden and Bawangling Nature Reserve, with relative frequency of 42·06 and 34·88% respectively. Another dominant species was Colletotrichum boninense in Wuzhishan and Jianfengling Nature Reserves, with relative frequency of 36·84 and 46·97% respectively. Among the selected 21 endophytic fungi, 17 strains (80·95%) had activity against at least one pathogenic bacteria, and 14 strains (66·67%) exhibited activity against at least one fungal pathogens. Neonectria macroconidialis showed strong inhibition against Staphylococcus aureus (inhibition zone being 20 mm), Bacillus subtilis (14 mm) and Streptococcus agalactiae (28 mm). Xylaria sp. showed strong inhibition against Escherichia coli (20 mm), Rhizoctonia solani (20 mm) and Sclerotinia sclerotiorum (17 mm). Verticillium bulbillosum showed great activity against Strep. agalactiae (32 mm) and Fusarium oxysporum (22 mm). These endophytic fungi showed potentials in medicine development. SIGNIFICANCE AND IMPACT OF THE STUDY Endophytic fungi from medicinal plants are an important source of novel and viable drugs. Cephalotaxus hainanensis Li is well known for leukaemia treatment and its endophytic fungi were isolated to investigate the diversity and antimicrobial activity. It was found that Ce. hainanensis Li had rich endophytic fungi, and some fungi showed strong antimicrobial activity against certain pathogens. These fungi can be used in medicine development.

Abstract
Right lobe living donor liver transplantation form a major source of liver allografts in Asia because of the scarcity of deceased donation. However, the transplant surgeons often face challenges while managing right lobe liver allografts due to variations in vascular anatomy. Such variations have led the transplant team to adopt modifications in existing techniques of inflow and outflow reconstruction. One of such variations is presence of multiple draining inferior right hepatic veins (IRHVs). This hepatic venous anomaly pose a lot of technical difficulties in the outflow reconstruction as second and/or third anastomosis to inferior vena cava is not always possible in limited retrohepatic space. Herein, we describe the "Single oval ostium technique" using dual synthetic vascular grafts ensuring a common outflow channel for all the hepatic veins.

Abstract
BACKGROUND The reconstruction of outflow is a crucial step in living donor liver transplantation. This study describes a suitable technique that uses synthetic vascular conduits in presence of multiple draining veins of right lobe of liver and the outcome of the recipients to evaluate safety of using multiple synthetic grafts. METHODS From March 2011 to September 2014, 325 patients underwent right lobe living donor liver transplantation. Expanded polytetra-fluoroethylene (ePTFE) grafts were used in total 155 of the liver allografts. Among these, 16 liver grafts required dual ePTFE grafts to reconstruct the outflow due to presence of multiple hepatic veins. RESULTS The mean diameters for venous branches of segment 5 (V5) and 8 (V8) were 5 mm (range, 4-8 mm) and 7 mm (range, 5-9 mm). The mean diameter of inferior right hepatic veins was 8 mm (7-10 mm). All the recipients who received the right liver with dual ePTFE grafts showed satisfactory inflow and outflow immediately after reconstruction as measured by Doppler flowmetry. Postoperative ultrasonographic studies showed no disturbances in outflow. Protocol dynamic computed tomography performed in the second postoperative month showed 100% patency rates of the artificial grafts. At median follow-up of 24 months graft survival was achieved in 88%, whereas the patency rates of the ePTFE grafts were 100%. CONCLUSION The use of "V-Plasty" technique using dual artificial vascular grafts is a safe and feasible technique in the presence of various allograft venous anomalies & ensures a single venous channel for outflow reconstruction. Our study also suggests that ePTFE graft may be a useful interposition material without serious complications.

Abstract
BACKGROUND Due to high prevalence of hepatitis B virus (HBV) infection in Taiwan, liver grafts from donors positive for hepatitis B surface antigen (HBsAg) without progressive disease can be effective alternative source of donor organs. This study aims to prove the safety of living donor liver transplantation (LDLT) using HBsAg-positive liver grafts and its long-term outcome. MATERIAL AND METHODS We studied 14 consecutive LDLT recipients that received HBsAg-positive grafts from November 2009 to December 2013 for various indications. All donors were chronic HBsAg carriers with normal liver function tests. Median follow-up was 46 months (range, 35-59). RESULTS All the donors and recipients recovered well post-transplant with no reactivation of HBV to date. Two of the recipients died due to extra-hepatic recurrence of HCC. At median follow-up of 46 months, 4-year cumulative survival of recipients was 77.38%. CONCLUSIONS In endemic areas, HBsAg-positive donor organs can clearly be used effectively under viral immunoprophylaxis. HBV disease reactivation does not appear to be a threat even with hepatitis B immunoglobulin (HBIG)-free antiviral monoprophylaxis regimen. This study thus proves the safety and feasibility of the option of using HBsAg-positive grafts in high-prevalence areas.

Abstract
From September 2012 to March 2013, a total of 63 adult-to-adult living donor liver transplantations were performed at our institution. All the patients were monitored for their coagulation functions using rotation thromboelastometry (ROTEM, Tem Innovations GmbH) during the procedure at the following points: preoperative baseline, 5 minutes, 30 minutes, and 120 minutes, respectively, after reperfusion of the liver graft. A total of 84.13% of cases (n = 53) revealed fibrinolysis after reperfusion of the graft and the condition was reversed after 30 minutes without any need for additional treatment. No significant coagulopathy was observed during this period in all of the cases. The result of the ROTEM finding must correlate with the clinical situation before instituting any management to avoid the risk of thrombosis of the hepatic artery.

Abstract
OBJECTIVE To investigate whether diabetes affects perioperative complications or mortality and to gauge its impact on medical expenditures for noncardiac surgeries. RESEARCH DESIGN AND METHODS With the use of reimbursement claims from the Taiwan National Health Insurance system, we performed a population-based cohort study of patients with and without diabetes undergoing noncardiac surgeries. Outcomes of postoperative complications, mortality, hospital stay, and medical expenditures were compared between patients with and without diabetes. RESULTS Diabetes increased 30-day postoperative mortality (odds ratio 1.84 [95% CI 1.46-2.32]), particularly among patients with type 1 diabetes or uncontrolled diabetes and patients with preoperative diabetes-related comorbidities, such as eye involvement, peripheral circulatory disorders, ketoacidosis, renal manifestations, and coma. Compared with nondiabetic control patients, coexisting medical conditions, such as renal dialysis (5.17 [3.68-7.28]), liver cirrhosis (3.59 [2.19-5.88]), stroke (2.87 [1.95-4.22]), mental disorders (2.35 [1.71-3.24]), ischemic heart disease (2.08 [1.45-2.99]), chronic obstructive pulmonary disease (1.96 [1.29-2.97]), and hyperlipidemia (1.94 [1.01-3.76]) were associated with mortality for patients with diabetes undergoing noncardiac surgery. Patients with diabetes faced a higher risk of postoperative acute renal failure (3.59 [2.88-4.48]) and acute myocardial infarction (3.65 [2.43-5.49]). Furthermore, diabetes was associated with prolonged hospital stay (2.30 [2.16-2.44]) and increased medical expenditures (1.32 [1.25-1.40]). CONCLUSIONS Diabetes increases postoperative 30-day mortality, complications, and medical expenditures in patients undergoing in-hospital noncardiac surgeries.

Abstract
Pitaya (Hylocereus undatus and H. polyrhizus Britt. & Rose), a perennial succulent plant grown in the tropics, is becoming an emerging and important fruit plant in Taiwan. In September of 2009 and 2010, a number of pitaya plants were found to have a distinctive canker on stems. The disease expanded quickly to most commercial planting areas in Taiwan (e.g., Pintung, Chiayi, and Chunghua). Symptoms on the stem were small, circular, sunken, orange spots that developed into cankers. Pycnidia were erumpent from the surface of the cankers and the stems subsequently rotted. After surface disinfestation with 0.1% sodium hypochloride, tissues adjacent to cankers were placed on acidified potato dextrose agar (PDA) and incubated at room temperature for 1 week, after which colonies with dark gray-to-black aerial mycelium grew. Hyphae were branched, septate, and brown and disarticulated into 0- to 1-septate arthrospores. Sporulation was induced by culturing on sterile horsetail tree (Casuarina equisetifolia) leaves. Conidia (12.79 ± 0.72 × 5.14 ± 0.30 μm) from pycnidia were one-celled, hyaline, and ovate. The internal transcribed spacer (ITS) region of ribosomal DNA was PCR amplified with primers ITS1 and ITS4 (2) and sequenced. The sequence (GenBank Accession No. HQ439174) showed 99% identity to Neoscytalidium dimidiatum (Penz.) Crous & Slippers (GenBank Accession No. GQ330903). On the basis of morphology and nucleotide-sequence identity, the isolates were identified as N. dimidiatum (1). Pathogenicity tests were conducted in two replicates by inoculating six surface-sterilized detached stems of pitaya with either mycelium or conidia. Mycelial plugs from 2-day-old cultures (incubated at 25°C under near UV) were inoculated to the detached stems after wounding with a sterile needle. Conidial suspensions (103 conidia/ml in 200 μl) were inoculated to nonwounded stems. Noninoculated controls were treated with sterile medium or water. Stems were then incubated in a plastic box at 100% relative humidity and darkness at 30°C for 2 days. The symptoms described above were observed on inoculated stems at 6 to 14 days postinoculation, whereas control stems did not develop any symptoms. N. dimidiatum was reisolated from symptomatic tissues. To our knowledge, this is the first report of N. dimidiatum causing stem canker of pitaya. References: (1) P. W. Crous et al. Stud.

Abstract
UNLABELLED Although organ transplants have been applied for decades, outcomes of somatic cell transplants remain disappointing, presumably due to lack of appropriate supporting stromal cells. Thus, cotransplantation with liver stromal cells, hepatic stellate cells (HSC), achieves long-term survival of islet allografts in mice by way of induction of effector T cell apoptosis and generation of regulatory T (Treg) cells. In this study we provide evidence both in vitro and in vivo that HSC can promote generation of myeloid-derived suppressor cells (MDSC). HSC-induced MDSC demonstrate potent immune inhibitory activity. Induction of MDSC is dependent on an intact interferon gamma signaling pathway in HSC and is mediated by soluble factors, suggesting that the specific tissue stromal cells, such as HSC, play a crucial role in regulating immune response by way of inflammation-induced generation of MDSC. Large amounts of MDSC can be propagated in vitro from bone marrow-derived myeloid precursor cells under the influence of HSC. CONCLUSION Cotransplantation with in vitro generated MDSC can effectively protect islet allografts from host immune attack. Local delivery of potent immune suppressor cells for cell transplants holds great clinical application potential.

Abstract
Hepatic stellate cells (HSCs) have demonstrated a strong T-cell inhibitory activity. In a mouse islet transplantation model, cotransplanted HSCs can protect islet allografts from rejection. The involved mechanism is not fully understood. We showed in this study that expression of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), an important apoptosis-inducing ligand, on HSCs was crucial in protection of islet allografts, since HSCs derived from TRAIL knockout mice demonstrated less inhibitory activity towards T-cell proliferative responses, and substantially lost their capacity in protecting cotransplanted islet allografts from rejection, suggesting that TRAIL-mediated T cell apoptotic death is important in HSC-delivered immune regulation activity.

Abstract
Mango (Mangifera indica L.) is an economically important fruit crop in the tropical and subtropical areas of the world. In southern Taiwan, mango is grown on 18,000 ha of hilly land mainly located in Tainan, Kaohsiung, and Pingtung. Tons (180,000) of mango with a value of NT$6.6 billion (US$206 million) are produced annually. In 2008, mango fruit rot disease was observed 1 week after harvest on 30 to 72% of stored mangoes collected from seven orchards in southern Taiwan. The initial symptom was a small, brown lesion and rot symptoms advanced progressively. Two predominant fungi were isolated from the margin of lesions on acidified potato dextrose agar (PDA with lactic acid, pH 3.8). Isolates of each fungal type were transferred to 2% water agar containing sterilized pine needles and exposed to near UV light to induce sporulation. For the first fungus, conidia obtained from pycnidia were ovate, one-celled, and hyaline, with an average length and width of 12.93 ± 0.93 × 6.98 ± 0.40 μm and an average length/width ratio of 1.85. To confirm the identity of the fungus, PCR amplification by universal primers, ITS1/ITS4, and DNA sequencing of the internal transcribed spacer (ITS1-5.8S-ITS2 rRNA gene cluster) were conducted. The internal transcribed spacer (ITS) sequence of ribosomal DNA of this fungus was analyzed and submitted to GenBank (Accession No. GQ421486). It showed a sequence identity of 100% with Neofusicoccum mangiferae (Syd. & P. Syd.) Crous, Slippers & A. J. L. Phillips) (GenBank Accession No. AY615185). For the second fungus, conidia obtained from pycnidia were fusiform, one-celled, and hyaline, with an average length and width of 22.87 ± 1.32 × 6.42 ± 0.46 μm and a length/width ratio of 3.53. The ITS sequence of ribosomal DNA of this fungus was analyzed and submitted to GenBank (Accession No. GQ421485). It showed a sequence identity of 100% with Botryosphaeria dothidea (Moug.: Fr.) Ces & De Not.) (GenBank Accession No. AY 786321). To test pathogenicity, four mango fruits were wounded with a sterile needle, inoculated with mycelium agar plugs (0.5 mm in diameter) excised from separate monoconidial cultures, and incubated in a plastic box with a 100% relative humidity for 2 days at room temperature. Brown lesions appeared on all wounded sites of each fungus 2 days postinoculation. In control experiments, sterile agar plugs were placed on the wounded mango fruits. These fruits remained completely free from symptoms throughout the experiment. The pathogen was reisolated from the lesions of inoculated fruits and identified as N. mangiferae and B. dothidea, thus fulfilling Koch's postulates. N. mangiferae and B. dothidea have been reported on mango trees in Australia and South Africa (1). To our knowledge, this is the first report of these fungi causing fruit rot of mango in Taiwan.

Abstract
UNLABELLED The liver is considered to be an immune-privileged organ that favors the induction of tolerance. The underlying mechanisms are not completely understood. Interestingly, liver transplants are spontaneously accepted in several animal models, but hepatocyte transplants are acutely rejected, suggesting that liver nonparenchymal cells may effectively protect the parenchymal cells from immune attack. We have shown the profound T cell inhibitory activity of hepatic stellate cells (HSCs). Thus, cotransplantation with HSCs effectively protects islet allografts from rejection in mice. In this study, using T cell receptor transgenic and gene knockout approaches, we provided definitive evidence that HSCs protected cotransplanted islet allografts by exerting comprehensive inhibitory effects on T cells, including apoptotic death in graft-infiltrating antigen-specific effector T cells and marked expansion of CD4(+) Forkhead box protein (Foxp)3(+) T regulatory (Treg) cells. All these effects required an intact interferon-gamma (IFN-gamma) signaling in HSCs, demonstrated by using HSCs isolated from IFN-gamma receptor 1 knockout mice. B7-H1 expression on HSCs, a product molecule of IFN-gamma signaling, was responsible for induction of T cells apoptosis, but had no effect on expansion of Treg cells, suggesting that undetermined effector molecules produced by IFN-gamma signaling is involved in this process. CONCLUSION Upon inflammatory stimulation, specific organ stromal cells (such as HSCs in the liver) demonstrate potent immune regulatory activity. Understanding of the mechanisms involved may lead to development of novel strategies for clinical applications in transplantation and autoimmune diseases.

Abstract
BACKGROUND Several genetic variants in transcription factor genes have been reported to be associated with Parkinson's disease (PD). The muscle segment homeobox drosophila homolog of 1 gene (MSX1) is a major upstream regulator of the dopaminergic neuronal subtype specification. AIMS OF THE STUDY To determine whether genetic variation in the coding region of the MSX1 gene plays a role in the etiology of PD. METHODS We searched for genetic variations in the coding region of the MSX1 gene in 202 patients with PD and 200 normal controls by PCR-single-strand conformation polymorphism (PCR-SSCP) and sequencing. RESULTS No mutation in the MSX1 gene was identified in our cohort. CONCLUSIONS Mutations in the coding region of the MSX1 gene play little or no role in the development of PD.

Abstract
BACKGROUND/AIMS The liver lies downstream of the gut, and is constantly exposed to bacteria. Liver dendritic cells (DC) are known to possess properties of tolerance, and respond to LPS differently when compared to conventional DC, but the underlying mechanisms are not completely understood. The aim of this study was to evaluate liver DC response to LPS stimulation. METHODS Liver or spleen derived DC were isoloated from mice treated with plasmid-GM-CSF hydrodynamic injection. The surface molecules and TLR4 expression on DC and cytokine productions of LPS stimulated DC were determinded by FACS analysis, ELISA and qPCR. The ability of DC to elicit T cell responses and differentiation were examined by MLR/CTL assay and qPCR for molecular markers related to Th1/Th2/Treg. RESULTS In this study, we demonstrated that the threshold of LPS stimulation for liver DC was markedly higher than spleen DC, even though the expression of TLR4 on both DCs was comparable. In contrast to spleen DC that produced high levels of IL-12 and induced Th1 response upon LPS stimulation, LPS-liver DC preferentially produced IL-10 and IL-27, instead of IL-12. In addition, liver DC induced T cell hyporesponsiveness, associated with selective expansion of CD4(+)Foxp3(+)T regulatory cells. Addition of exogenous IL-12 only slightly enhanced liver DC-induced T cell response. Interestingly, abrogation of IL-27 ligation by using IL-27R(-/-) T cells synergistically augmented the effect of IL-12, suggesting that IL-27 produced by liver DC plays a crucial role in induction of T cell hyporesponsiveness. CONCLUSIONS Liver DC respond distinctly to LPS stimulation by secreting IL-27 which synergizes with silencing of bioactive IL-12 activity leading to profound T cell inhibition.

Abstract
Production of avocado (Persea americana) has increased significantly during the last 10 years in Taiwan and the area of cultivation is approximately 500 ha. The most important postharvest disease of avocado is anthracnose caused by Colletotrichum gloeosporioides (Penz.) in Taiwan (1). In 2008, a new disease was found to be infecting avocado fruit at some orchards in Tainan County of southern Taiwan. Infected avocados developed smooth, brown, circular spots first on the surface of harvested fruits. A fungus was always isolated from the margin of lesions and could also be found from symptomless fruit pedicles and stems. Fungal colonies cultured on acidified potato dextrose agar (PDA with lactic acid; pH 3.8) were initially colorless, turned dark gradually, and ultimately became gray to dark gray. After 4 days under fluorescent light at 25°C, pycnidia formed on PDA. Conidia obtained from fruiting bodies were ovate, one celled, and hyaline, with an average length and width of 12.9 (9.9 to 15.6) × 6.4 (5.2 to 7.2) μm. The internal transcribed spacer (ITS) sequence of ribosomal DNA of this fungus was analyzed and submitted to GenBank (No. EU847427). It showed a sequence identity of 99% with Neofusicoccum mangiferae ((Syd. & P. Syd.) Crous, Slippers & A.J.L. Phillips) (GenBank No. AY615185). Thus, both morphological and molecular results confirmed the isolated fungus as N. mangiferae. Five avocado fruits were used to test the pathogenicity with three different treatment inoculation sites on each fruit. Wounded and unwounded sites on fruit were inoculated with mycelia agar plugs (0.5 mm in diameter) excised from a monoconidial culture and the fruit was kept in a plastic box with high humidity for 2 days at room temperature. Brown lesions appeared on all wounded sites 2 days postinoculation (dpi) and on unwounded sites at 4 dpi. The pathogen was reisolated from the lesions of inoculated fruits and found to be N. mangiferae, thus fulfilling Koch's postulates. In control experiments, sterile agar plugs were placed on the wounded avocado fruits. These fruits remained completely free from symptoms throughout the experiment. Several species of Botryosphaeria have been reported on avocado, including N. parvum (anamorph of B. parva), Fusicoccum aesculi (anamorph of B. dothidea), and Dothiorella aromatica (= F. luteum). To our knowledge, this is the first report of N. mangiferae causing fruit rot of avocado in Taiwan. Previously, N. mangiferae has been reported on mango trees worldwide, especially in Australia and Thailand (2). The presence of N. mangiferae in the subtropical area presents a serious disease problem not only to avocado but also to mango. References: (1) Y. P. Tsai, ed.
