Abstract
The liquid-phase reduction method for the preparation of metal nanoparticles (NPs) by the reduction of metal salts or metal complexes in a solvent with a reducing agent is widely used to prepare Ni NPs that exhibit high catalytic activity in various organic transformations. Intensive research has been conducted on control of the morphology and size of Ni NPs by the addition of polymers and long-chain compounds as protective agents; however, these agents typically cause a decrease in catalytic activity. Here, we report on the preparation of Ni NPs using hydrosilane (Ni-Si) as a reducing agent and a size-controlling agent. The substituents on silicon can control not only the size but also the crystal phase of the Ni NPs. The prepared Ni NPs exhibited high catalytic performance for the hydrogenation of unsaturated compounds, aromatics, and heteroaromatics to give the corresponding hydrogenated products in high yields. The unique feature of Ni catalysts prepared by the hydrosilane-assisted method is that the catalysts can be handled under air as opposed to conventional Ni catalysts such as Raney Ni. Characterization studies indicated that the surface hydroxide was reduced under the catalytic reaction conditions with H2 at around 100 °C and with the assistance of organosilicon compounds deposited on the catalyst surface. The hydrosilane-assisted method presented here could be applied to the preparation of supported Ni catalysts (Ni-Si/support). The interaction between the Ni NPs and a metal oxide support enabled the direct amination of alcohols with ammonia to afford the primary amine selectively.

Abstract
Portosystemic venous shunts occur in patients with polysplenia after the Fontan operation. In the long term, these shunts are associated with hyperammonaemia and portal-systemic encephalopathy. Since some shunts are long and tortuous, catheter interventions to close them could be challenging. Instead, a steerable microcatheter could be used for coil embolisation of tortuous portosystemic venous shunts.

Abstract
A 63-year-old woman was admitted with abdominal pain two months after laparoscopic abdominoperineal resection for rectal cancer. Computed tomography revealed dilated small intestine had passed through a defect between the lifted sigmoid colon and abdominal wall. She was diagnosed with small bowel obstruction without strangulation due to internal hernia and managed nonoperatively based on her wish. Recurrence of intestinal obstruction occurred for which curative surgery was performed laparoscopically. The herniated intestine was restored to the normal position, and the hernia orifice was closed using barbed suture, on laparoscopic management. Internal hernia is a rare complication after colostomy that requires surgical management. Although laparoscopic approach on re-operation is difficult, laparoscopic surgery may be suitable for patients with IHAC in terms of required less use of adhesiolysis.

Abstract
BACKGROUND Shifting enables flexible switch between tasks or mental sets. It is a component of the executive function that plays critical roles in human behaviour control. However, shifting ability in individuals with intellectual disability (ID) has not been well clarified because of the use of intellectually demanding tasks in previous studies. The present study invented a novel shifting task with minimal intellectual demands and aimed to clarify the characteristics of shifting in adolescents with ID. METHODS Adolescents with ID (n = 21) and chronological-age-matched (n = 10) and mental-age-matched controls (n = 33) performed a novel shifting task with simple rule switching (i.e. change in direction). Analyses focused on the switch cost or the increase in the reaction time associated with rule switching. RESULTS Two subtypes of adolescents with ID were found with respect to the switch cost: one that lacks it and another with an increased switch cost. The lack of a switch cost was unique to the subgroup adolescents with ID and was not indicated in the control group. CONCLUSIONS The present study indicated that shifting in adolescents with ID does not depend solely on their intellectual function and is highly heterogeneous. This finding further implies that executive functions, including shifting, must be evaluated separately from their intellectual functions.

Abstract
A 64-year-old man presented to the emergency department with a chief complaint of epigastric pain that improved with vomiting. He was initially treated for gastrointestinal disease, but computed tomography (CT) showed a mediastinal haematoma and contrast-enhanced CT and bronchial arteriography showed a bronchial aneurysm. Bronchial artery aneurysm is a rare but potentially life-threatening condition that can lead to haemorrhagic shock if it ruptures. Patients with bronchial aneurysms may present with symptoms similar to that of gastrointestinal diseases owing to increased pressure in the mediastinum caused by mediastinal haematoma.

Abstract
A 54-year-old male with alcoholic cirrhosis and diabetes mellitus was referred to our hospital for the treatment of right pleural empyema with fistula. Despite performing a simple suture closure of the pulmonary fistula, air leakage occurred one week after surgery. Hence, we covered the fistula with a pediculed muscle flap associated with an open window thoracostomy. After 32 days of gauze drainage, negative pressure wound therapy( NPWT) was introduced for reducing the residual pleural space. A chest computed tomography( CT) scan showed almost the full expansion of the lung after undergoing 98 days of NPWT. The patient was discharged from the hospital four months after thoracostomy.

Abstract
RATIONALE Hormone therapies, particularly those targeting estrogen and its receptors, are a key treatment modality for patients with estrogen receptor (ER)-positive breast or ovarian cancer. Some gastric cancers (GCs) express ERs, and preclinical studies suggest the potential of estrogen-targeting hormone therapy on GC; however, the clinical relevance of this hormone therapy on GC treatment has not been well elucidated. PATIENT CONCERNS An 80-year-old female was admitted to our department with hypogastric pain and vomiting. Computed tomography demonstrated small bowel obstruction, and laparotomy after bowel decompression revealed peritoneal dissemination consisting of a poorly-differentiated adenocarcinoma. Intestinal bypass between the ileum and transverse colon was performed. DIAGNOSES The tumor was ER- and mammaglobin-positive, indicating that it originated from a breast cancer. Diagnostic imaging revealed no evidence of breast cancer; however, right axillary ER- and mammaglobin-positive lymphadenopathy was found. INTERVENTIONS The patient received hormone therapy using letrozole based on a clinical diagnosis of occult breast cancer with peritoneal dissemination and right axillary lymph node metastasis. OUTCOMES The patient remained disease free until 37 months but deceased at 53 months from the onset of disease. An autopsy revealed no tumor cells in the right breast tissue; however, there was a massive invasion of cancer cells in the stomach. LESSONS A patient with ER positive GC with peritoneal dissemination and right axillary lymph node metastasis presented remarkable response to letrozole. The long-term survival obtained using letrozole for a patient with GC with distant metastasis suggests the potential of estrogen targeting hormone therapies for GC.

Abstract
BACKGROUND FOLFOX therapy, a standard treatment for colorectal cancer (CRC), causes a rare, but serious adverse event, hyperammonemia. However, the risk factors of hyperammonemia remain unknown. METHODS We examined 74 patients who received mFOLFOX6 therapy with or without biologics for CRC between April 2013 and March 2018 in Yaizu City Hospital. Clinicopathological factors were retrospectively reviewed in association with hyperammonemia, and risk factors of hyperammonemia during mFOLFOX6 therapy were analyzed in 32 patients with the available data. RESULTS Seven patients developed hyperammonemia, with onset exclusively on day 2 or 3 in the first cycle of therapy. They were treated with branched chain amino acid administration and hydration; however, one patient with stage G4 chronic kidney disease (CKD) died. By multivariate analysis, estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 was independently associated with hyperammonemia during FOLFOX therapy (odds ratio: 9.0, p = 0.040). CONCLUSIONS Reduced eGFR is considered a risk factor of developing hyperammonemia during FOLFOX therapy. Serum ammonia levels should be monitored especially during the first cycle of FOLFOX therapy in patients with CKD stage G3 or higher.

Abstract
A 61-year-old woman, who was revealed to have a 11 mm pulmonary nodule in the right middle lobe by computed tomography, was diagnosed with adenocarcinoma using bronchoscopy. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed FDG accumulation in the tumor, with a maximum standardized uptake value( SUVmax) of 2.47. Therefore, she underwent thoracoscopic right middle lobectomy. Histopathological examination revealed invasive growth of cylindrical tumor cells with clear glycogen-filled cytoplasm and a relatively high-grade nuclear atypia in tubulopapillary structures; no morula was observed. Immunohistochemically, the membranes of the tumor cells were positively stained for β-catenin, indicating high-grade fetal adenocarcinoma (pT1bN0M0, pathologic stageⅠA2). The postoperative course was uneventful, without recurrence 6 months after surgery.

Abstract
The pathogenic bacterium Staphylococcus aureus can penetrate host cells. However, intracellular S. aureus is not considered during antimicrobial agent selection in clinical chemotherapy because of the lack of information about drug transportability into cells in vivo. We focused on agents used to treat methicillin-resistant S. aureus (MRSA) (vancomycin, arbekacin, linezolid, and daptomycin) and indirectly assessed the drug levels in intracellular compartment using plasma, tissue homogenates, and interstitial fluid (ISF) samples from the skin of rats using the microneedle array technique. Lower drug levels were observed in the ISF than in the plasma for daptomycin but extracellular and intracellular drug levels were comparable. In contrast, vancomycin, arbekacin, and linezolid showed higher concentrations in the ISF than in the plasma. Intracellular transport was estimated only for arbekacin. Stasis of vancomycin in the ISF was also observed. These results suggest that both low vancomycin exposure against intracellular S. aureus infection and long-term subinhibitory drug levels in the ISF contribute to the failure of treatment and emergence of antibiotic resistance. Based on its pharmacokinetic characteristics in niche extravascular tissue spaces, arbekacin may be suitable for achieving sufficient clinical outcomes for MRSA infection because the drug is widely distributed in extracellular and intracellular compartments.

Abstract
Heterogeneously catalysed synthesis of primary amines by direct amination of alcohols with ammonia has long been an elusive goal. In contrast to reported Ru-based catalytic systems, we report that Ru-MgO/TiO2 acts as an effective heterogeneous catalyst for the direct amination of a variety of alcohols to primary amines at low temperatures of ca. 100 °C without the introduction of H2 gas. The present system could be applied to a variety of alcohols and provides an efficient synthetic route for 2,5-bis(aminomethyl)furan (BAMF), an attention-getting biomonomer. The high catalytic performance can be rationalized by the reactivity tuning of Ru-H species using MgO. Spectroscopic measurements suggest that MgO enhances the reactivity of hydride species by electron donation from MgO to Ru.

Abstract
Background: Amyloidosis treatment has advanced rapidly along with the discovery of drugs to prevent amyloid deposition. Therefore, it is vital to detect amyloidosis at an early stage. Wild-type transthyretin, which can cause carpal tunnel syndrome, may also cause finger tenosynovitis. However, the correlation between wild-type transthyretin amyloid and finger tenosynovitis is unclear. Here, we investigated pathological and clinical findings for 20 patients with finger tenosynovitis who underwent operation at our hospital to determine the frequency of transthyretin amyloid deposition in idiopathic finger tenosynovitis. Methods: To check for the presence of amyloid deposition, all specimens (tendon synovium tissue or flexor tendon sheath) resected during the operation were stained by the direct fast scarlet method. Amyloid-positive specimens were evaluated by immunohistochemical staining using an anti-transthyretin antibody. Patient characteristics were evaluated with respect to amyloid presence. Results: Thirteen (65%) of 20 finger tenosynovitis cases had amyloid deposition. Nine (69.2%) of the 13 amyloid-positive cases exhibited extensive transthyretin staining and were considered to have transthyretin amyloid. Amyloid deposition was more frequent in men. The mean number of fingers with tenosynovitis was significantly higher in amyloid-positive cases (3.8 fingers) than in amyloid-negative cases (2.0 fingers). Conclusions: Men with multiple finger tenosynovitis tended to have transthyretin amyloid deposition. Our results support that multiple finger tenosynovitis may serve as an initial indication of evaluation for transthyretin amyloidosis.

Abstract
A 74-year-old man underwent right upper lobectomy and systemic lymph node dissection with video-assisted thoracoscopic surgery. Chylothorax occurred on postoperative day (POD) 1st. Under fasting management, the patient underwent pleurodesis on POD 5th and 7th, subcutaneous octreotide acetate injection on POD 6th, and lymphangiography on POD 9th. The amount of drainage decreased on POD 10th, and the drainage tube was removed on POD 12nd. Lymphangiography has been reported as one of effective procedures to treat postoperative chylothorax. The present case is also considered to be successfully treated by lymphangiography.

Abstract
PURPOSE Bronchopleural fistula (BPF) is a potential serious complication of lobectomy or more radical surgery for non-small-cell lung cancer (NSCLC). We aimed to evaluate the risk factors for BPF. METHODS The study cohort comprised 635 patients who had undergone lobectomy or more radical surgery for NSCLC from March 2005 to December 2017. We examined the following risk factors for BPF: surgical procedure, medical history, preoperative treatment, and surgical management. RESULTS In all, 10 patients (1.6%) had developed postoperative BPFs. Univariate logistic regression analysis showed that surgical procedure, medical history (arteriosclerosis obliterans [ASO]), and bronchial stump reinforcement were significant risk factors. Multivariate analysis showed that only surgical procedure (right lower lobectomy, p = 0.011, odds ratio = 17.4; right middle lower lobectomy, p = 0.003, odds ratio = 59.4; right pneumonectomy, p <0.001, odds ratio = 166.0) was a significant risk factor. Multivariate analysis confined to the surgical procedure of lobectomy showed that right lower lobectomy (p = 0.011, odds ratio = 36.5) and diabetes (HbA1c ≥8.0) (p = 0.022, odds ratio = 31.7) were significant risk factors. CONCLUSION When lobectomy or more radical surgery is performed for NSCLC, right lower lobectomy, middle lower lobectomy, and right pneumonectomy are significant risk factors for postoperative BPF. Thoracic surgeons should acquire the techniques of bronchoplasty and angioplasty to avoid such invasive procedures.

Abstract
BACKGROUND/AIM GPR87 is a member of the cell surface molecular G protein-coupled receptors (GPCR) family and suggested to contribute to the viability of human tumor cells. Its tumor-specific expression and cell surface location make it a potential molecule for targeted therapy. In the present study, we aimed to examine the effect of silencing GPR87 expression and explore the possibility of establishing gene therapy against GPR87-overexpressing lung cancer. MATERIALS AND METHODS Twenty malignant cell lines were investigated and GPR87-overexpressing H358 and PC9 lung cancer cells were subjected to inhibiting experiments. A short hairpin siRNA targeting the GPR87 gene was transformed into an adenoviral vector (Ad-shGPR87). Real-time RT-PCR and western blot analyses were performed to evaluate gene and protein expression. Tumors derived from human H358 cells were subcutaneously implanted in nude mice for in vivo experiments. RESULTS AND CONCLUSION About 50% (10/20) malignant cells showed GPR87-overexpression, especially for lung cancer cells (70%, 7/10). Ad-shGPR87 effectively down-regulated the GPR87 expression, and significantly inhibited the cell proliferation in GPR87-overexpressing H358 and PC9 cells. Treatment with Ad-shGPR87 exerted a significant antitumor effect against the GPR87-expressing H358 xenografts. In addition, the gene expression of H3.3, a recently proved activator for GPR87 transcription, was positively correlated with GPR87 gene expression. Furthermore, a significant decrease of KRAS and c-Myc expression was observed in both cell lines after Ad-shGPR87 infection. In conclusion, GPR87 may play a critical role in cancer cell proliferation, and indicate its potential as a novel target for lung cancer treatment.

Abstract
Background
Stroke and cardiovascular disease are one of the leading causes of death and disability in Japan. In order to investigate current burden, we conduct a population-based registry of cardiovascular disease in Shiga Prefecture, Japan since 2012. We will demonstrate challenges in conduct of the registry study.
Methods
In 2012, we established the Shiga Stroke Registry (SSR), a multicenter population-based registry study designed to build a complete information system for the management of stroke in Shiga Prefecture, Japan. The registry uses local monitoring, combined with remote data collection and quality control systems, to create an integrated surveillance system among a network of all acute care hospitals with neurology/neurosurgery facilities and smaller hospitals with rehabilitation facilities in the region. In 2019, study name has changed to Shiga Stroke and Heart Attack Registry (SSHR) and additional registration of coronary heart disease and aortic disease have started. Each case is reviewed and adjudicated by 2 or more specialists.
Results
In the financial year of 2018 (from April to March), a total of 4809 stroke cases were identified. From December 2018 to April 2019, a total of 515 coronary heart and aortic diseases were identified. A total 10 nurses work full-time for the registry and it takes average of 1 hour to collect information for each patient. Challenges in conduct of the cardiovascular registry involve regulatory and ethical approval, funding, associations with local hospitals, non-standardized hospital diagnosis, staff training for comprehensive data collection including pathophysiology, examination and treatment, and quality control of data collection.
Conclusions
SSHR is a population-based registry of wide range of stroke and cardiovascular disease in Shiga Prefecture, Japan. In order to keep quality of the data, we put a lot of efforts on staff training and quality control.

Abstract
BACKGROUND Histoplasmosis is considered a fairly rare imported mycosis in Japan. Here we report a case of histoplasmosis describing the preoperative findings, histopathological findings, supposed infection route, and appropriate treatment, including the postoperative management. CASE PRESENTATION A healthy 65-year-old man was found at routine medical check-up to have an abnormal opacity on chest radiography. A chest computed tomography (CT) scan showed a nodular lesion in the posterior basal segment of the right lung, as well as two smaller nodules in the same lobe. This was highly suggestive of primary lung cancer with pulmonary metastases in the same lobe. We thus performed a right lower lobectomy with hilar and mediastinal lymph node dissection via thoracotomy. The lesions were diagnosed as pulmonary histoplasmosis on histopathology. At 6-month follow-up examination, the patient was free from fungal infection without any postoperative medication. CONCLUSIONS We describe a patient with pulmonary histoplasmosis diagnosed following surgical lobectomy. The possibility of pulmonary histoplasmosis should be considered in the differential diagnosis of pulmonary nodular lesions.

Abstract
Background Locating small, non-palpable lung tumors during video-assisted thoracoscopic surgery (VATS) is difficult. In this paper, we report a simple method to identify such tumors during VATS, using intraoperative computed tomography (IO-CT). Methods From 2015 to 2017, we performed IO-CT scans for patients who preoperatively seemed to have non-palpable lung tumors. We initially tried to locate these tumors by finger palpation through the thoracoscopic ports. IO-CT scans were performed after marking tumors with metal clips. However, difficult-to-palpate tumors were marked by initially locating the intercostal muscle from preoperative CT. Metal clips were applied just under the intercostal muscle, and IO-CT scans were performed. After locating the tumor in relationship to the marking clips, patients would undergo wedge resections during VATS, using surgical staplers. Results We used this procedure on 21 tumors in 18 patients, including 9 non-palpable tumors and 12 palpable tumors (mean tumor size: 7.3 mm; mean distance from pleura: 6.8 mm). All tumors were identified intraoperatively, and all patients successfully underwent wedge resections during VATS, with no intra-postoperative complications. Conclusion IO-CT scans after tumor marking with metal clips during VATS can accurately locate non-palpable small sized lung tumors. IO-CT scans should be indicated for tumors that are preoperatively considered to be non-palpable.

Abstract
BACKGROUND Several studies have shown that diabetes confers a higher relative risk of vascular mortality among women than among men, but whether this increased relative risk in women exists across age groups and within defined levels of other risk factors is uncertain. We aimed to determine whether differences in established risk factors, such as blood pressure, BMI, smoking, and cholesterol, explain the higher relative risks of vascular mortality among women than among men. METHODS In our meta-analysis, we obtained individual participant-level data from studies included in the Prospective Studies Collaboration and the Asia Pacific Cohort Studies Collaboration that had obtained baseline information on age, sex, diabetes, total cholesterol, blood pressure, tobacco use, height, and weight. Data on causes of death were obtained from medical death certificates. We used Cox regression models to assess the relevance of diabetes (any type) to occlusive vascular mortality (ischaemic heart disease, ischaemic stroke, or other atherosclerotic deaths) by age, sex, and other major vascular risk factors, and to assess whether the associations of blood pressure, total cholesterol, and body-mass index (BMI) to occlusive vascular mortality are modified by diabetes. RESULTS Individual participant-level data were analysed from 980 793 adults. During 9·8 million person-years of follow-up, among participants aged between 35 and 89 years, 19 686 (25·6%) of 76 965 deaths were attributed to occlusive vascular disease. After controlling for major vascular risk factors, diabetes roughly doubled occlusive vascular mortality risk among men (death rate ratio [RR] 2·10, 95% CI 1·97-2·24) and tripled risk among women (3·00, 2·71-3·33; χ2 test for heterogeneity p<0·0001). For both sexes combined, the occlusive vascular death RRs were higher in younger individuals (aged 35-59 years: 2·60, 2·30-2·94) than in older individuals (aged 70-89 years: 2·01, 1·85-2·19; p=0·0001 for trend across age groups), and, across age groups, the death RRs were higher among women than among men. Therefore, women aged 35-59 years had the highest death RR across all age and sex groups (5·55, 4·15-7·44). However, since underlying confounder-adjusted occlusive vascular mortality rates at any age were higher in men than in women, the adjusted absolute excess occlusive vascular mortality associated with diabetes was similar for men and women. At ages 35-59 years, the excess absolute risk was 0·05% (95% CI 0·03-0·07) per year in women compared with 0·08% (0·05-0·10) per year in men; the corresponding excess at ages 70-89 years was 1·08% (0·84-1·32) per year in women and 0·91% (0·77-1·05) per year in men. Total cholesterol, blood pressure, and BMI each showed continuous log-linear associations with occlusive vascular mortality that were similar among individuals with and without diabetes across both sexes. INTERPRETATION Independent of other major vascular risk factors, diabetes substantially increased vascular risk in both men and women. Lifestyle changes to reduce smoking and obesity and use of cost-effective drugs that target major vascular risks (eg, statins and antihypertensive drugs) are important in both men and women with diabetes, but might not reduce the relative excess risk of occlusive vascular disease in women with diabetes, which remains unexplained.

Abstract
Highly selective synthesis of primary amines over heterogeneous catalysts is still a challenge for the chemical industry. Ruthenium nanoparticles supported on Nb2O5 act as a highly selective and reusable heterogeneous catalyst for the low-temperature reductive amination of various carbonyl compounds that contain reduction-sensitive functional groups such as heterocycles and halogens with NH3 and H2 and prevent the formation of secondary amines and undesired hydrogenated byproducts. The selective catalysis of these materials is likely attributable to the weak electron-donating capability of Ru particles on the Nb2O5 surface. The combination of this catalyst and homogeneous Ru systems was used to synthesize 2,5-bis(aminomethyl)furan, a monomer for aramid production, from 5-(hydroxymethyl)furfural without a complex mixture of imine byproducts.

Abstract
e20054 Background: Ribonucleotide reductase M1 (RRM1) is involved in regulation of cell proliferation and synthesis of deoxyribonucleotides for DNA. It is also a cellular target for gemcitabine (GEM) and overexpression of RRM1 was reported to be associated with the resistance to GEM. Though RRM1 expression has been reported as the biomarkers in predicting the response to chemotherapy clinically, the value of GEM remains inconsistent and controversial. Collagen gel droplet embedded culture-drug sensitivity test (CD-DST) is a newly developed in vitro chemosensitivity test that could directly inspect the anti-cancer drug sensitivity with fresh tumor tissue. With use of CD-DST test, we have verified the predictive value of RRM1 expression to the anti-cancer agent sensitivity for GEM in non-small cell lung cancer (NSCLC) tumor. Here, the predictive value of biomarker RRM1 to GEM was further verified with CD-DST. Methods: Twenty-five patients with primary NSCLC were used in this study. Expression of RRM1 was assessed by immunohistochemistry. For CD-DST test, viable cells were collected from fresh surgical specimen and embed into the collagen gel droplets in 3D condition. Tumor cells were exposed to GEM for 1 hour and further incubated with serum-free culture medium for 7 days. The in vitro sensitivity was expressed as the percentage T/C ratio, where T was the total volume of the treated group and C was the total volume of the control group. Results: 1)Anti-cancer drug sensitivity: The sensitivity for GEM (T/C%) was 76.2 ± 30.5. 2)Expression of biomarkers: RRM1 expression was 39.2 ± 28.2 %. 3) Correlation: The expression of RRM1 significantly correlated with drug sensitivity for GEM (r = 0.446, p = 0.0256). Higher expression of RRM1 indicated worse anti-cancer drug sensitivity for GEM. Conclusions: The significant correlation between the RRM1 expression and sensitivity to GEM was proved with CD-DST in NSCLC tumors. The expression of RRM1 may become a useful biomarker in predicting the drug sensitivity for GEM in NSCLC.

Abstract
e23152 Background: GPR87 is a newly deorphanized member of the G protein-coupled receptor family, it was suggested to contribute to the viability of human tumor cells, and overexpression of GPR87 was found in many malignant tumors including lung cancer. To explore effective gene therapies, we previously reported that adenoviral vector expressing short hairpin RNA targeting GPR87 (Ad-shGPR87) exerts a strong anti-proliferation activity against GPR87-overexprssing human bladder cancer cells. Here, the effect of Ad-shGPR87 was further examined in lung cancer cells. Methods: Human lung cancer cells of EBC, H358, LUDLU, MAC10 and RERF were investigated. Two cell of adenocarcinoma cell H358 (Ad) and squamous cell carcinoma cell LUDLU with an overexpression of GPR87 were selected for experiment. An adenoviral vector expressing short hairpin siRNA targeting GPR87 gene (Ad-shGPR87) was constructed by the COS-TPC method with Adenovirus Expression Vector kit (Takara Biomedicals). Real-time RT-PCR was performed to evaluate gene expressions. MTT assay was used to evaluate the cell viability. A human tumor xenograft model in nude mice was prepared by subcutaneously implanting tumors derived from H358 cells. Results: Transfection with Ad-shGPR87 effectively downregulated the GPR87 expression in both cells (more than 90% 3 days after transfection). MTT assay demonstrated the transfection of Ad-shGPR87 strongly suppressed the cell viability (less than 6.6 % for LUDLU cell and 20.0% for H358 cell at nine days after transfection). Furthermore, the treatment with Ad-shGPR87 exerted a significant antitumor effect against the GPR87-overexpressing H358 xenografts. Conclusions: The cancer gene therapy using Ad-shGPR87 has a strong anti-tumor effect both in vitro and in vivo against the GPR87-overexpressing lung cancer cells. GPR87 appear to be a promising target for cancer therapy.

Abstract
71-year-old woman was pointed out to have an asymptomatic mediastinal tumor. Chest computed tomography(CT) showed a well-demarcated mass measuring 7 cm in diameter in the anterior mediastinum. We resected the mass through a median sternotomy. The tumor had a clear margin without invasion to the surrounding tissue and did not show continuity with the cervical thyroid gland. Histopathologically, the tumor was diagnosed as follicular thyroid carcinoma with capsular invasion. This is an exceptionally rare case.

Abstract
High CD44 expression is associated with enhanced malignant potential in esophageal squamous cell carcinoma (ESCC), amongst the deadliest of all human carcinomas. Although alterations in autophagy and CD44 expression are associated with poor patient outcomes in various cancer types, the relationship between autophagy and cells with high CD44 expression remains incompletely understood. In transformed esophageal keratinocytes, CD44Low-CD24High (CD44L) cells give rise to CD44High-CD24−/Low (CD44H) cells via epithelial-mesenchymal transition (EMT) in response to transforming growth factor (TGF)-β. We couple patient samples and xenotransplantation studies with this tractable in vitro system of CD44L to CD44H cell conversion to investigate the functional role of autophagy in generation of cells with high CD44 expression. We report that high expression of the autophagy marker cleaved LC3 expression correlates with poor clinical outcome in ESCC. In ESCC xenograft tumors, pharmacological autophagy inhibition with chloroquine derivatives depletes cells with high CD44 expression while promoting oxidative stress. Autophagic flux impairment during EMT-mediated CD44L to CD44H cell conversion in vitro induces mitochondrial dysfunction, oxidative stress and cell death. During CD44H cell generation, transformed keratinocytes display evidence of mitophagy, including mitochondrial fragmentation, decreased mitochondrial content and mitochondrial translocation of Parkin, essential in mitophagy. RNA interference-mediated Parkin depletion attenuates CD44H cell generation. These data suggest that autophagy facilitates EMT-mediated CD44H generation via modulation of redox homeostasis and Parkin-dependent mitochondrial clearance. This is the first report to implicate mitophagy in regulation of tumor cells with high CD44 expression, representing a potential novel therapeutic avenue in cancers where EMT and CD44H cells have been implicated, including ESCC.

Abstract
Background Pulmonary torsion is usually caused by thoracic surgery or trauma. Spontaneous pulmonary torsion caused by tumor and pleural effusion is very rare. Case presentation A 76-year-old Asian male with a chronic cough and suspected lung or pleural tumor presented with sudden dyspnea. Computed tomography showed that the right upper lung lobe contained a large tumor in the region of S1-3; the tumor had shifted to the posterior thoracic space and rotated 90° counterclockwise, potentially impeding blood flow. The patient underwent emergency right upper lobectomy for torsion of the right upper lung lobe. He recovered uneventfully and was discharged without complications. Conclusions We experienced a rare case of spontaneous torsion of the right upper lung lobe caused by a large tumor and massive pleural effusion.

Abstract
A CePO4 catalyst exhibits high catalytic performance for the chemoselective acetalization of 5-hydroxymethylfurfural with alcohols, in sharp contrast to other homogeneous and heterogeneous acid and/or base catalysts.
Acid–base solid catalysts synthesized with structurally controlled uniform active sites can lead to unique catalysis. In this study, a CePO4 catalyst was synthesized using a hydrothermal method and found to exhibit high catalytic performance for the chemoselective acetalization of 5-hydroxymethylfurfural with alcohols, in sharp contrast to other homogeneous and heterogeneous acid and/or base catalysts. In the presence of CePO4, various combinations of carbonyl compounds and alcohols are efficiently converted into the corresponding acetal derivatives in good to excellent yields. Mechanistic studies show that CePO4 most likely acts as a bifunctional catalyst through the interaction of uniform Lewis acid and weak base sites with 5-hydroxymethylfurfural and alcohol molecules, respectively, which results in high catalytic performance.

Abstract
The goals of the Japanese chapter of the Transplant Recipients International Organization are to act as a mediator in the provision of mutual aid to transplant recipients, candidates, and their families and to provide education in both the public and professional arenas to promote organ transplantation in Japan. Since 1991, members of the Japanese chapter of the Transplant Recipients International Organization have acted as volunteer facilitators for more than 150 transplant candidates and recipients. The organization's activities have included fund-raising to cover the costs of transplantation, preparing an original donor card for distribution, and petitioning members of the Diet (the Japanese legislative body) 14 times, including speaking at public hearings twice and submitting a petition requesting early passage of the organ transplant bill. The Japanese Diet finally passed an organ transplant bill in June 1997. The activities of the Japanese chapter of the Transplant Recipients International Organization have contributed to the promotion of organ transplantation in Japan and to understanding and support for transplantation within the Japanese community as a whole.

Abstract
Although organ transplantation following brain death has progressed in the West, it has lagged far behind in Japan, following the first such case in 1968. As effective immunosuppressants made transplantation a better option, Japanese patients increasingly sought treatment overseas. Japanese physician groups studied issues related to transplantation but did not succeed in making brain-dead donor transplants available to patients, and the matter was referred to the government. However, transplant medicine was still marked by controversy, and as political pressure was applied the controversy deepened, splintering public opinion. At the same time, transplant groups continued working to establish structures to allow transplantation to proceed. Public awareness and knowledge of brain death grew, and acceptance widened. Eventually, legislation was passed in June 1997 that allowed organ donations from some brain-dead donors. The law is restrictive, and such organ transplants in Japan are still limited.

Abstract
Iridium(III) complexes bearing chiral ligands have proved to be active species in asymmetric hydrogenation of C=N bonds, though there are only a few iridium(III) precursors. We prepared triply halide-bridged dinuclear iridium complexes bearing chiral diphosphine ligands by simple treatment of the iridium(I) precursor, chiral diphosphine, and aqueous hydrogen halide. The strong advantage of these dinuclear iridium complexes is that they are air and moisture stable, leading to easy handling in asymmetric synthesis. The dinuclear iridium complexes exhibited high catalytic activity toward asymmetric hydrogenation of imines and N-heteroaromatics. Moreover, we demonstrated the application of triply halide-bridged dinuclear ruthenium(II) and rhodium(III) catalyst precursors for the asymmetric hydrogenation of ketonic substrates and simple olefins, respectively.

Abstract
Efficient rhodium(III) catalysts were developed for asymmetric hydrogenation of simple olefins. A new series of chloride-bridged dinuclear rhodium(III) complexes 1 were synthesized from the rhodium(I) precursor [RhCl(cod)]2 , chiral diphosphine ligands, and hydrochloric acid. Complexes from the series acted as efficient catalysts for asymmetric hydrogenation of (E)-prop-1-ene-1,2-diyldibenzene and its derivatives without any directing groups, in sharp contrast to widely used rhodium(I) catalytic systems that require a directing group for high enantioselectivity. The catalytic system was applied to asymmetric hydrogenation of allylic alcohols, alkenylboranes, and unsaturated cyclic sulfones. Control experiments support the superiority of dinuclear rhodium(III) complexes 1 over typical rhodium(I) catalytic systems.

Abstract
Asymmetric allylic alkylation of β-ketoesters with allylic alcohols catalyzed by [Ni(cod)2]/(S)-H8-BINAP was found to be a superior synthetic protocol for constructing quaternary chiral centers at the α-position of β-ketoesters. The reaction proceeded in high yield and with high enantioselectivity using various β-ketoesters and allylic alcohols, without any additional activators. The versatility of this methodology for accessing useful and enantioenriched products was demonstrated.
