Abstract
We aimed to clarify the relationship between intra- and peri-organ fat, visceral fat, and subcutaneous fat. We used abdominal CT to evaluate intra- and peri-organ fat accumulations in the pancreas, liver, spleen, renal parenchyma, renal sinus, and skeletal muscle. The relationships between these fats, visceral fat, and subcutaneous fat were examined by using the partial correlation and covariance analysis, adjusting for BMI. We found that visceral fat and each intraand peri-organ fat accumulation were positively correlated, whereas subcutaneous fat and the accumulation of each intra- and peri-organ fat and visceral fat were negatively correlated. Pancreas fat, liver fat, renal sinus fat, and skeletal muscle fat accumulated significantly more in people with excessive visceral fat accumulation than in those without excessive visceral fat accumulation (p = 0.01, 0.006, 0.008, 0.02, respectively). In conclusion, intra- and peri-organ fat accumulation in each organ shows a positive correlation with visceral fat and a negative correlation with subcutaneous fat, independent of BMI.

Abstract
BACKGROUND & AIMS Ectopic fat deposition is associated with worsening of glycemic control. This study was conducted to determine whether liraglutide reduces ectopic fat deposition, especially in pancreas, in patients with type 2 diabetes (T2D). METHODS We retrospectively recruited T2D patients who underwent abdominal unenhanced CT scans both before and after administration of liraglutide (N = 13) or glimepiride (N = 29). Using CT values of pancreas (P), liver (L) and spleen (S), we defined the indices of intrapancreatic and liver fat as P-S value and L-S value, respectively. Increase of each value suggests the reduction of each fat deposition. RESULTS The values of HbA1c (p = 0.0017) and body weight (p = 0.0081) decreased, and L-S (p = 0.0024) increased significantly after administration of liraglutide compared with those at baseline. Similarly, P-S tended to increase in the liraglutide group (p = 0.0547) and increased significantly in the liraglutide subgroup with fatty pancreas (p = 0.0303), defined as having baseline P-S less than -5. In the glimepiride group, P-S did not increase regardless of baseline P-S. Among patients with fatty pancreas, administration of liraglutide tended to be a significant factor for the change in P-S after adjustment for the change in HbA1c (p = 0.1090) and the change in visceral fat area (p = 0.1030). CONCLUSIONS Intrapancreatic fat deposition was decreased after treatment with liraglutide, but not glimepiride, in T2D patients with fatty pancreas. Liraglutide might reduce intrapancreatic fat deposition independently of decreases in HbA1c and visceral fat volume.

Abstract
Background This pilot study examined the feasibility of a new lifestyle modification program involving a "Teaching Kitchen" in Japan. Our goal was to explore (1) feasibility of the program; (2) acceptability for class frequency (weekly vs. bi-weekly); and (3) changes in biometrics, dietary intakes, and lifestyle factors. Methods A total of 24 employees with obesity in a Japanese company were recruited. Participants were randomly divided into two groups (weekly or bi-weekly group), each attending the program consisting of four two-hour classes (lectures on nutrition, exercise, mindfulness, and culinary instructions). Participants were observed for changes in dietary intakes, biometrics, and health related quality of life over the subsequent 3 months. We tested the between-group differences in changes using linear mixed-effect models. Results The program completion rates were 83.3% in total (91.7% for weekly group and 75.0% for bi-weekly group). From baseline to post-intervention, significant decreases were observed in weight (p < 0.001), body mass index (p < 0.001), diastolic blood pressure (p = 0.03), body fat mass (p < 0.001), and dietary intakes in total fat (p = 0.03) and sodium (p = 0.008) among 17 participants who were available for measurements. Improvements in biometrics remained significant 1 month after the intervention (all p ≤ 0.03 in 14 participants). Participants' health related quality of life was significantly improved in bodily pain, general health, vitality, and mental component score (all p ≤ 0.047). Conclusions The new Japanese Teaching Kitchen program is feasible with high program completion rates in Japanese office workers with obesity. While this was a small feasibility study, significant multiple improvements in dietary intakes, biometrics, and health related quality of life suggest that this line of inquiry warrants further exploration to address obesity and obesity-related diseases in Japan.

Abstract
Aims The excess deposition of intra-pancreatic fat deposition (IPFD) has been reported to be associated with type 2 diabetes, chronic pancreatitis, and pancreatic ductal adenocarcinoma. In the current study, we aimed to identify a relationship between lifestyle factors and IPFD. Materials and methods 99 patients admitted to the Osaka University Hospital who had undergone abdominal computed tomography were selected. We evaluated the mean computed tomography values of the pancreas and spleen and then calculated IPFD score. Multiple regression analyses were used to assess the associations between IPFD score and lifestyle factors. Results Fast eating speed, late-night eating, and early morning awakening were significantly associated with a high IPFD score after adjusting for age, sex, diabetes status and Body Mass Index (p=0.04, 0.01, 0.01, respectively). Conclusion The current study has elucidated the significant associations of fast eating speed, late-night eating, and early morning awakening with IPFD.

Abstract
Immune checkpoint inhibitors (ICIs) could cause type 1 diabetes (T1D). However, the underlying mechanism remains unclear. We immunohistochemically analyzed pancreatic specimens from three individuals with ICI-related T1D, and their histopathological data were compared those from three patients who had received ICI therapy but did not develop T1D (non-T1D) and seven normal glucose-tolerant subjects as control subjects. All ICI-related T1D patients had susceptible HLA haplotypes. In ICI-related T1D, the β-cell area decreased and the α-cell area increased compared with non-T1D and control subjects. The number of CD3-positive cells around islets increased in ICI-related T1D and non-T1D compared with control subjects, while the number of CD68-positive cells around islets increased in ICI-related T1D compared with non-T1D and control subjects. The expression ratios of programmed death-ligand 1 (PD-L1) on islets decreased in non-T1D and almost completely disappeared in ICI-related T1D, while PD-L1 expression was observed in most cells of pancreatic islets in control subjects. This study, therefore, indicates that ICI therapy itself could reduce PD-L1 expression on islets in all subjects, which may be related to β-cell vulnerability. In addition, we showed that absence of PD-L1 expression on β-cells, genetic susceptibility, and infiltration of macrophages as well as T lymphocytes around islets might be responsible for T1D onset.

Abstract
BACKGROUND Ectopic fat is fat that accumulates in or around specific organs or compartments of the body including myocardium. The clinical features of type 2 diabetes patients with high fat accumulation in the myocardium remain unknown. Moreover, little is known about the influence of myocardial fat accumulation in type 2 diabetes on coronary artery disease and cardiac dysfunction. We aimed to clarify the clinical features, including cardiac functions, of type 2 diabetes patients with myocardial fat accumulation. METHODS We retrospectively enrolled type 2 diabetes patients who underwent ECG-gated coronary computed tomography angiography (CCTA) and abdominal computed tomography (CT) scan examinations within 1 year of CCTA from January 2000 to March 2021. High fat accumulation in the myocardium was defined as the low mean myocardial CT value of three regions of interest, and the associations between CT values and clinical characteristics or cardiac functions were assessed. RESULTS In total, 124 patients were enrolled (72 males and 52 females). The mean age was 66.6 years, the mean BMI was 26.2 kg/m2, the mean ejection fraction (EF) was 67.6%, and the mean myocardial CT value was 47.7 Hounsfield unit. A significant positive correlation was found between myocardial CT value and EF (r = 0.3644, p = 0.0004). The multiple regression analyses also showed that myocardial CT value was independently associated with EF (estimate, 0.304; 95% confidence interval (CI) 0.092 to 0.517; p = 0.0056). Myocardial CT value showed significant negative correlations with BMI, visceral fat area and subcutaneous fat area (r = - 0.1923, - 0.2654, and -0.3569, respectively, p < 0.05). In patients who were ≥ 65 years or female, myocardial CT value showed significant positive correlations with not only EF (r = 0.3542 and 0.4085, respectively, p < 0.01) but also early lateral annular tissue Doppler velocity (Lat e') (r = 0.5148 and 0.5361, respectively, p < 0.05). The multiple regression analyses showed that myocardial CT value was independently associated with EF and Lat e' in these subgroups (p < 0.05). CONCLUSIONS Patients with type 2 diabetes, especially in elderly or female patients, who had more myocardial fat had more severe left ventricular systolic and diastolic dysfunctions. Reducing myocardial fat accumulation may be a therapeutic target for type 2 diabetes patients.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a common disease, and endoscopic sinus surgery (ESS) is widely performed. However, there is no consensus regarding postoperative pain control after ESS, and postoperative opioid abuse is a problem in many countries. Acetaminophen is reportedly effective for postoperative pain control. Preemptive analgesia has received more attention lately, wherein pain is prevented before it occurs. In this study, we assessed the use of acetaminophen for preemptive analgesia during the perioperative period in ESS. METHODOLOGY This is a retrospective study of 175 patients who underwent ESS, septoplasty, and bilateral inferior turbinate mucosal resection at our hospital from April 2016 to February 2018. In total, 82 patients received 1,000 mg of acetaminophen during surgery and 4 hours after the first dose, while 93 patients did not receive it routinely. We compared these two groups. The primary outcome was the need to use additional analgesics prescribed by the ward physician and the secondary outcomes included postoperative pain, postoperative bleeding, reoperation, blood pressure, and body temperature. RESULTS The use of additional oral and intravenous analgesics was significantly reduced in the patients who received acetaminophen perioperatively. CONCLUSION Preemptive analgesia during the perioperative period of ESS could lead to satisfactory postoperative pain control.

Abstract
Background Prior reports have suggested that pancreatic fat is related to type 2 diabetes. Sodium‐glucose co‐transporter‐2 (SGLT‐2) inhibitors are expected to reduce ectopic fat accumulation. Aim This study assessed the effect of SGLT‐2 inhibitors on pancreatic and liver fat accumulations in patients with type 2 diabetes. Materials and Methods Retrospective analyses of indices of pancreatic and liver fat accumulations were conducted in 22 type 2 diabetes outpatients who were receiving SGLT‐2 inhibitors for more than 12 weeks. The differences between the pancreatic (P) or liver (L) and splenic (S) computed tomography values were evaluated. Results Fatty pancreas was defined as P−S < −8 Hounsfield Unit (HU), and the number of patients with fatty pancreas was 11 (50%). Fatty pancreas significantly improved after SGLT‐2 inhibitor use (median, −20.8; IQR, −34.8 to −14.3 HU vs. median, −14.6; IQR, −29.5 to −7.8 HU; p = 0.041). Fatty liver was defined as L−S ≤ 3.9 HU, and the number of patients with fatty liver was 11 (50%). Fatty liver significantly improved after SGLT‐2 inhibitor use (median, −4.3; IQR, −23.0 to 3.0 HU vs. median, −0.7; IQR, −5.2 to 6.3 HU; p = 0.016). Conclusion Pancreatic fat and liver fat accumulations might be reduced after treatment with SGLT‐2 inhibitors in type 2 diabetes patients with intense cumulative fat depositions in these organs.

Abstract
Objective This study aimed to clarify the clinical significance of the maximum body mass index (BMI) before the onset of type 2 diabetes (MBBO) for predicting pancreatic beta-cell function. Methods This was a cross-sectional observational study. Of 1304 consecutively admitted patients with type 2 diabetes, we enrolled 410 patients satisfying the criteria in this study. The correlations between the C-peptide index (CPI), which is one of the parameters that reflects beta-cell function, and various clinical parameters, including MBBO and duration of diabetes, were analyzed in multiple linear regression analyses. Results The analyses revealed that MBBO was correlated with CPI independently after adjustment for age, sex, HbA1c, and duration of diabetes. When we divided the subjects into three subgroups by MBBO (MBBO < 25 kg/m2; 25 kg/m2 ≤ MBBO < 30 kg/m2; MBBO ≥ 30 kg/m2), CPI was negatively correlated with duration of diabetes in each subgroup, while the rates of CPI based on the duration of diabetes were not different among the three MBBO subgroups. In contrast, the declining rates of CPI were higher in the BMI ≥ 25 kg/m2 group on admission than in the BMI < 25 kg/m2 group on admission. Conclusions MBBO may be an independent factor correlating with beta-cell function and may predict insulin secretion capacity at diagnosis, but it does not seem to affect the rate of decline in insulin secretion capacity after diagnosis. It is important to preserve beta-cell function by decreasing a patient’s BMI during treatment after diagnosis regardless of MBBO.

Abstract
Abstract
Four-dimensional flow magnetic resonance imaging (4D flow MRI) provides the detailed visualization of complex blood flow patterns and the evaluation of energy loss. Turbulent kinetic energy estimation (TKE) is reported to have good correlation with irreversible pressure loss in patients having aortic stenosis or great vessel disease. However, little is known about the usefulness of 4D flow MRI and the significance of TKE value in hypertrophic cardiomyopathy (HCM).
Purpose
The aims of this study were to investigate the relationship between TKE value and echocardiographic findings, clinical symptoms and evaluate the usefulness of 4D flow MRI to distinguish hypertrophic obstructive cardiomyopathy (HOCM) from non-obstructive HCM (HNCM).
Methods
From April 2018 to January 2019, 18 hypertrophic obstructive cardiomyopathy (HOCM) and 14 non-obstructive HCM (HNCM) patients underwent 4D flow MRI. We investigated TKE value calculated by 4D flow MRI, echocardiographic findings; left ventricular pressure gradient (LVPG), mitral regurgitation (MR) and clinical symptom.
Results
HOCM was defined by the 30 mmHg or greater of LVPG (HOCM: 87.7±47.3 mmHg, HNCM; 5.8±7.8 mmHg, p<0.001). TKE value in HOCM patients was significantly higher than HNCM (14.2±4.7 mJ vs. 9.0±4.6 mJ, p<0.001). There was a significant positive linear relationship between TKE value and LVPG (r=0.488, p=0.046). There was no significant relationship between NYHA functional class and TKE value (p=0.47) or LVPG (p=0.11). ROC curve analysis showed that optimal cut off point of TKE value between HOCM and HNCM (sensitivity=95%, specificity=62%, AUC=0.798) was 9.270 mJ. Multiple linear regression showed that there was significant association between severity of MR and combination of TKE (p=0.015) or LVPG (p–=0.012). A representative case demonstrated the significant reduction of TKE value 1 week and 3 months after alcohol septal reduction compared with that obtained before the procedure (Figure)
Conclusion
Our findings suggest that 4D Flow MRI can effectively evaluate the energy dissipation associated with LV outflow tract obstruction and TKE value is useful for identifying HOCM. TKE value also can be the novel parameter of the severity of HOCM.

Abstract
Background
Thrombolysis has been recommended for high-risk pulmonary embolism (PE) in ESC guidelines, used as a reference in Japan. Recently, indication of thrombolysis for acute PE has been limited with recent guideline revision. Little is known regarding trends of treatment strategy and mortality in high-risk PE patients.
Purpose
To clarify temporal trends of treatment strategy and short-term outcomes in high-risk PE patients.
Methods
A retrospective analysis of therapeutic interventions and short-term outcomes was performed for 52 consecutive high-risk PE patients including cardiac arrest. According to timing of ESC guidelines update (2000, 2008 and 2014), patients were divided into four time periods: 1992 to 2000, 2001 to 2008, 2009 to 2014, and 2015 to 2018.
Results
Mean age and proportion of male were not different over the period. Nosocomial case decreased from 100% to 25% (p<0.01). Postoperative cases (relative contraindication for thrombolysis) included 43% of all patients. Cardiac arrest and VA-ECMO use were 42% and 21% of all patients. Any thrombolytic therapy including catheter-directed intervention showed a non-significant decrease trend (92%-87%-71%-44%, p=0.067). Temporary or retrieval IVC filter insertion showed a significant downward trend (36%-80%-54%-22%, p=0.025). The entire study 30-day mortality was 23%. There was no significant difference in 30-day mortality over the periods (14%-27%-14%-44%, p=0.303). However, major bleeding decreased significantly (71%-40%-7%-22%, p=0.004) (Table).
Table 1 1992–2000 (n=14) 2001–2008 (n=15) 2009–2014 (n=14) 2015–2018 (n=9) p Age (years) 54±12 59±17 64±13 65±16 0.224 Male 29% 13% 29% 44% 0.269 Any thrombolytic therapy 92% 87% 71% 44% 0.067 Catheter-directed therapy 86% 87% 71% 0% <0.01 with thrombolytics (92%) (83%) (90%) without thromboloytics (8%) (17%) (10%) Only intravenous thrombolysis 8% 7% 7% 44% 0.038 Temporary/retrieval IVC filter 36% 80% 54% 22% 0.025 ICU stay (days) 15±14 10±18 5±4 8±8 0.206 30-day mortality 14% 27% 14% 44% 0.303 Major bleeding 71% 40% 7% 22% 0.004
Conclusion
The temporal analysis identified a decreased trend in any thrombolytic therapy and IVC filter insertion in high-risk PE. The study also found a decreasing trend in major bleeding.

Abstract
We reviewed fulminant type 1 diabetes, a recently established subtype of type 1 diabetes, from the aspects of genes, viruses, immune mechanism and usefulness of patient-derived induced pluripotent stem cells (iPSCs). In an analysis of the pancreas of patients with fulminant type 1 diabetes, viral antigens and viral receptors were expressed in β-cells, as well as macrophages and T lymphocytes surrounding the β-cells. These findings suggest that the β-cells of patients with fulminant type 1 diabetes are destroyed during an immune response against viral infection of the pancreas. Recently, fulminant type 1 diabetes was induced by treatment with anti-programmed cell death 1 antibodies, suggesting that immune regulatory mechanisms are also involved in the onset of this disease. We generated iPSCs from patients with fulminant type 1 diabetes for the first time. We also successfully differentiated patient-derived iPSCs into insulin-producing cells in vitro, and produced a disease model. The proportion of cytokine-induced apoptotic cells among insulin-positive cells was higher in the iPSCs from patients with fulminant type 1 diabetes than in iPSCs from healthy control participants. We carried out ribonucleic acid sequencing in insulin-producing cells differentiated from patient-derived iPSCs, and are now attempting to identify new biomarkers for the disease.

Abstract
Introduction To investigate the efficacy of the transplantation of autologous bone marrow-derived mesenchymal stem cells (BMSCs) under arthroscopy with microfracture (MFX) compared with microfracture alone. Methods Eleven patients with a symptomatic articular cartilage defect of the knee were included in the study. They were randomized to receive BMSCs with MFX (cell-T group, n=7) or MFX alone (control group, n=4). Clinical results were evaluated using International Knee Documentation committee (IKDC) knee evaluation questionnaires and the Knee Injury and Osteoarthritis Outcome Score (KOOS) before and 48 weeks after surgery. Quantitative and qualitative assessments of repair tissue were carried out at 48 weeks by T2 mapping of magnetic resonance images (MRIs) and the magnetic resonance observation of cartilage repair tissue (MOCART) scoring system with follow-up MRI. Results No significant differences between preoperative and postoperative IKDC and KOOS were observed in the cell-T or control group. However, forty-eight weeks after surgery, the cell-T group showed a trend for a greater KOOS QOL score compared with the control group (79.4 vs. 39.1, respectively; P=0.07). The T2 value did not differ significantly between the two groups, but the mean MOCART score was significantly higher in the cell-T group than in the control group (P=0.02). Conclusions Compared with MFX alone, BMSC transplantation with MFX resulted in better postoperative healing of the cartilage and subchondral bone as determined by the MOCART score. Clinically, BMSC transplantation with MFX gave a higher KOOS QOL score after 48 weeks. This is the first prospective randomized clinical trial between BMSCs with MFX and MFX alone. BMSCs with MFX showed a trend for a greater KOOS QOL score compared with MFX alone. BMSCs with MFX resulted in better healing of the cartilage by the MOCART score.

Abstract
Aims Glucagon plays pivotal roles in systemic glucose homeostasis mainly by promoting hepatic glucose output. Using a sandwich enzyme-linked immunosorbent assay (ELISA), we evaluated fasting plasma glucagon levels in hospitalized patients with type 1 or type 2 diabetes, and assessed the relationships between glucagon levels and various clinical parameters. Methods We enrolled adult Japanese diabetes patients admitted to Osaka University Medical Hospital for glycemic control between July 2017 and May 2018 in this study. After patients had fasted for 12 h, blood samples were obtained and plasma glucagon levels were measured using a sandwich ELISA. Results Total 107 patients participated in the study. The mean fasting plasma glucagon level of patients with acute onset type 1 diabetes was significantly lower than that of patients with type 2 diabetes (p < 0.05). Plasma glucagon levels were not significantly correlated with plasma glucose levels in patients with type 1 diabetes or in patients with type 2 diabetes. Multiple regression analysis indicated that fasting glucagon levels were independently and significantly correlated with fasting serum C-peptide levels in patients with type 2 diabetes. Conclusions Our results suggest that insulin and glucagon secretion are balanced in the fasting state in patients with type 2 diabetes.

Abstract
In this paper, we report the development and demonstration of a method to fabricate an all-glass microfluidic cell culturing device without circulation flow. On-chip microfluidic cell culturing is an indispensable technique for cellular replacement therapies and experimental cell biology. Polydimethylsiloxane (PDMS) have become a popular material for fabricating microfluidic cell culture devices because it is a transparent, biocompatible, deformable, easy-to-mold, and gas-permeable. However, PDMS is also a chemically and physically unstable material. For example, PDMS undergoes aging easily even in room temperature conditions. Therefore, it is difficult to control long term experimental culturing conditions. On the other hand, glass is expected to be stable not only in physically but also chemically even in the presence of organic solvents. However, cell culturing still requires substance exchanges such as gases and nutrients, and so on, which cannot be done in a closed space of a glass device without circulation flow that may influence cell behavior. Thus, we introduce a filter structure with micropores onto a glass device to improve permeability to the cell culture space. Normally, it is extremely difficult to fabricate a filter structure on a normal glass plate by using a conventional fabrication method. Here, we demonstrated a method for fabricating an all-glass microfluidic cell culturing device having filters structure. The function of this all-glass culturing device was confirmed by culturing HeLa, fibroblast and ES cells. Compared with the closed glass devices without a filter structure, the numbers of cells in our device increased and embryonic bodies (EBs) were formed. This method offers a new tool in microfluidic cell culture technology for biological analysis and it expands the field of microfluidic cell culture.

Abstract
AIMS/INTRODUCTION The present study was carried out to generate induced pluripotent stem cells (iPSCs) from patients with fulminant type 1 diabetes, and evaluate the cytokine-induced apoptotic reactions of β-like insulin-producing cells differentiated from the iPSCs. MATERIALS AND METHODS iPSCs were generated from fibroblasts of patients with fulminant type 1 diabetes by inducing six reprogramming factors. Insulin-producing cells were differentiated from the iPSCs in vitro. The proportion of cleaved caspase-3-positive or terminal deoxynucleotidyl transferase 2'-deoxyuridine, 5'-triphosphate nick end labeling-positive cells among insulin (INS)-positive cells derived from fulminant type 1 diabetes iPSC and control human iPSC lines was evaluated under treatment with tumor necrosis factor-α, interleukin-1β and interferon-γ. Ribonucleic acid sequencing was carried out to compare gene expressions in INS-positive cells derived from fulminant type 1 diabetes iPSC and control human iPSC lines. RESULTS Two iPSC clones were established from each of three patients with fulminant type 1 diabetes. The differentiation of insulin-producing cells from fulminant type 1 diabetes iPSC was confirmed by immunofluorescence analysis and KCl-induced C-peptide secretion. After treatment with pro-inflammatory cytokines, these INS-positive cells showed higher expression of cleaved caspase-3 than those derived from control human iPSCs. Altered expression levels of several apoptosis-related genes were observed in INS-positive cells derived from the fulminant type 1 diabetes iPSCs by ribonucleic acid sequencing. CONCLUSIONS We generated iPSCs from patients with fulminant type 1 diabetes and differentiated them into insulin-producing cells. This in vitro disease model can be used to elucidate the disease mechanisms of fulminant type 1 diabetes.

Abstract
AIMS/HYPOTHESIS Pancreatic beta-like cells generated from human induced pluripotent stem cells (hiPSCs) or human embryonic stem cells (hESCs) offer an appealing donor tissue source. However, differentiation protocols that mainly use growth factors are costly. Therefore, in this study, we aimed to establish efficient differentiation protocols to change hiPSCs/hESCs to insulin (INS)+ cells using novel small-molecule inducers. METHODS We screened small molecules that increased the induction rate of INS+ cells from hESC-derived pancreatic and duodenal homeobox 1 (PDX1)+ pancreatic progenitor cells. The differentiation protocol to generate INS+ cells from hiPSCs/hESCs was optimised using hit compounds, and INS+ cells induced with the compounds were characterised for their in vitro and in vivo functions. The inducing activity of the hit compounds was also examined using mouse embryonic pancreatic tissues in an explant culture system. Finally, RNA sequencing analyses were performed on the INS+ cells to elucidate the mechanisms of action by which the hit compounds induced pancreatic endocrine differentiation. RESULTS One hit compound, sodium cromoglicate (SCG), was identified out of approximately 1250 small molecules screened. When SCG was combined with a previously described protocol, the induction rate of INS+ cells increased from a mean ± SD of 5.9 ± 1.5% (n = 3) to 16.5 ± 2.1% (n = 3). SCG induced neurogenin 3-positive cells at a mean ± SD of 32.6 ± 4.6% (n = 3) compared with 14.2 ± 3.6% (n = 3) for control treatment without SCG, resulting in an increased generation of endocrine cells including insulin-producing cells. Similar induction by SCG was confirmed using mouse embryonic pancreatic explants. We also confirmed that the mechanisms of action by which SCG induced pancreatic endocrine differentiation included the inhibition of bone morphogenetic protein 4 signalling. CONCLUSIONS/INTERPRETATION SCG improves the generation of pancreatic endocrine cells from multiple hiPSC/hESC lines and mouse embryonic pancreatic explants by facilitating the differentiation of endocrine precursors. This discovery will contribute to elucidating the mechanisms of pancreatic endocrine development and facilitate cost-effective generation of INS+ cells from hiPSCs/hESCs.

Abstract
Screening for oncogenes has mostly been performed by in vitro transformation assays. However, some oncogenes might not exhibit their transforming activities in vitro unless putative essential factors from in vivo microenvironments are adequately supplied. Here, we have developed an in vivo screening system that evaluates the tumorigenicity of target genes. This system uses a retroviral high-efficiency gene transfer technique, a large collection of human cDNA clones corresponding to ~70% of human genes and a luciferase-expressing immortalized mouse mammary epithelial cell line (NMuMG-luc). From 845 genes that were highly expressed in human breast cancer cell lines, we focused on 205 genes encoding membrane proteins and/or kinases as that had the greater possibility of being oncogenes or drug targets. The 205 genes were divided into five subgroups, each containing 34-43 genes, and then introduced them into NMuMG-luc cells. These cells were subcutaneously injected into nude mice and monitored for tumor development by in vivo imaging. Tumors were observed in three subgroups. Using DNA microarray analyses and individual tumorigenic assays, we found that three genes, ADORA2B, PRKACB and LPAR3, were tumorigenic. ADORA2B and LPAR3 encode G-protein-coupled receptors and PRKACB encodes a protein kinase A catalytic subunit. Cells overexpressing ADORA2B, LPAR3 or PRKACB did not show transforming phenotypes in vitro, suggesting that transformation by these genes requires in vivo microenvironments. In addition, several clinical data sets, including one for breast cancer, showed that the expression of these genes correlated with lower overall survival rate.

Abstract
Dumon® Y-stents and Dynamic stents are used to treat carinal stenosis, but their placement severely impairs the expectoration of secretions, making frequent bronchoscopic aspiration necessary. We report here five patients with terminal lung cancer who had stenosis of the lower trachea and main bronchi treated using spiral Z-stents. A long tapered spiral Z-stent was placed in the lower trachea and one main bronchus, and a short straight spiral Z-stent in the contralateral main bronchus. No patients required bronchoscopic aspiration of secretions after stenting. Before stenting, all of the patients were severely dyspnoeic, requiring oxygen and having to sit in the orthopnoeic position. After stenting, the patients' dyspnoea improved, with one patient becoming ambulant without the need for oxygen support. These results suggest that the use of spiral Z-stents in stenosis of the tracheal carina in advanced lung cancer is effective in reducing the need for bronchoscopic aspiration and enhancing quality of life.

Abstract
Abstract
Background: Diffuse optical spectroscopic imaging (DOSI) can be exploited as a marker of tumor blood volume quantified by tissue hemoglobin (tHb) concentration. In DOSI, frequent measurement is possible for breast cancer patients because of its non-invasiveness. The tHb concentration determined by DOSI is expected to be a new biomarker for prediction of breast cancer response to neoadjuvant chemotherapy (NAC).
Purpose: Our objective is to determine whether early change of tumor tHb concentration predicts pathological complete response (pCR) to NAC in patients with operable breast cancer.
Methods: In a prospective study, one hundred patients with primary breast cancer were enrolled for primary objective analysis. The regimens of NAC were according to the standard of care. Patients underwent sequential scans using DOSI at baseline, after 1st course and 2nd course of chemotherapy. The mean value of tHb (tHbmean) concentration of the targeted lesion was measured and the percentage change in tHbmean (ΔtHbmean) concentration was calculated. Receiver operating curve analysis demonstrated diagnostic performance of DOSI for predicting a pCR.
Results: In interim analysis, it was regarded as a good outcome that area under the curve (AUC) for ΔtHbmean after 1nd course was 0.797 (SE 0.104, 95%CI 0.633-0.911), and after 2st course was 0.867 (SE 0.06, 95%CI 0.715-0.956).
Conclusion: DOSI could predict accurately a pCR to neoadjuvant chemotherapy in patients with primary breast cancer.

Abstract
Aims Viral infection is associated with pancreatic beta cell destruction in fulminant type 1 diabetes mellitus. The aim of this study was to investigate the acceleration and protective mechanisms of beta cell destruction by establishing a model of viral infection in pancreatic beta cells. Methods Polyinosinic:polycytidylic acid was transfected into MIN6 cells and insulin-producing cells differentiated from human induced pluripotent stem cells via small molecule applications. Gene expression was analyzed by real-time PCR, and apoptosis was evaluated by caspase-3 activity and TUNEL staining. The anti-apoptotic effect of Exendin-4 was also evaluated. Results Polyinosinic:polycytidylic acid transfection led to elevated expression of the genes encoding IFNα, IFNβ, CXCL10, Fas, viral receptors, and IFN-inducible antiviral effectors in MIN6 cells. Exendin-4 treatment suppressed the elevated gene expression levels and reduced polyinosinic:polycytidylic acid-induced apoptosis both in MIN6 cells and in insulin-producing cells from human induced pluripotent stem cells. Glucagon-like peptide-1 receptor, protein kinase A, and phosphatidylinositol-3 kinase inhibitors counteracted the anti-apoptotic effect of Exendin-4. Conclusions Polyinosinic:polycytidylic acid transfection can mimic viral infection, and Exendin-4 exerted an anti-apoptotic effect both in MIN6 and insulin-producing cells from human induced pluripotent stem cells.

Abstract
AIMS Abnormalities in the imprinted locus on chromosome 6q24 are the most common causes of transient neonatal diabetes mellitus (6q24-related transient neonatal diabetes). 6q24-Related transient neonatal diabetes is characterized by the patient being small-for-gestational age, diabetes mellitus at birth, spontaneous remission within the first few months and frequent recurrence of diabetes after childhood. However, it is not clear whether individuals with 6q24 abnormalities invariably develop transient neonatal diabetes. This study explored the possibility that 6q24 abnormalities might cause early-onset, non-autoimmune diabetes without transient neonatal diabetes. METHODS The 6q24 imprinted locus was screened for abnormalities in 113 Japanese patients with early-onset, non-obese, non-autoimmune diabetes mellitus who tested negative for mutations in the common maturation-onset diabetes of the young (MODY) genes and without a history of transient neonatal diabetes. Positive patients were further analysed by combined loss of heterozygosity / comparative genomic hybridization analysis and by microsatellite analysis. Detailed clinical data were collected through the medical records of the treating hospitals. RESULTS Three patients with paternal uniparental isodisomy of chromosome 6q24 were identified. None presented with hyperglycaemia in the neonatal period. Characteristically, these patients were born small-for-gestational age, representing 27.2% of the 11 patients whose birth weight standard deviation score (SDS) for gestational age was below -2.0. CONCLUSIONS Abnormalities in the imprinted locus on chromosome 6q24 do not necessarily cause transient neonatal diabetes. Non-penetrant 6q24-related diabetes could be an underestimated cause of early-onset, non-autoimmune diabetes in patients who are not obese and born small-for-gestational age.

Abstract
OBJECTIVES Plumbagin (PL), a naturally occurring quinoid, exerts antitumoral effects in diverse types of cancer cells. However, the effect of PL on tumor cell proliferation in oral squamous cell carcinoma (OSCC) remains poorly understood. In this study, we assessed the efficacy of PL, in human OSCC cells. METHODS The effect of PL on the cell growth and apoptosis of OSCC cell lines was evaluated using MTT and Annexin V assays, respectively. The effect of PL on mitochondrial membrane potential loss and reactive oxygen species (ROS) generation was evaluated using flow cytometry analysis. RESULTS MTT assay showed that PL dose-dependently suppressed OSCC cell growth, with IC50 values ranging from 3.87 to 14.6 μM. Flow cytometry analysis revealed that PL treatment resulted in a significant decrease in mitochondrial membrane potential and an increase in the number of apoptotic cells. Notably, ROS generation was significantly elevated after PL treatment. Furthermore, a ROS scavenger, N-acetylcysteine (NAC), clearly suppressed the decrease in mitochondrial membrane potential, increase of caspase-3/7 activity, and apoptosis after PL treatment. CONCLUSION This study provides the considerable evidence of the tumor-suppressive effect of PL, thereby highlighting its therapeutic potential for OSCC treatment.

Abstract
AIMS To investigate the molecular and clinical characteristics of the largest series of Japanese patients with glucokinase maturity-onset diabetes of the young (GCK-MODY), and to find any features specific to Asian people. METHODS We enrolled 78 Japanese patients with GCK-MODY from 41 families (55 probands diagnosed at the age of 0-14 years and their 23 adult family members). Mutations were identified by direct sequencing or multiplex ligation-dependent probe amplification of all exons of the GCK gene. Detailed clinical and laboratory data were collected on the probands using questionnaires, which were sent to the treating physicians. Data on current clinical status and HbA1c levels were also collected from adult patients. RESULTS A total of 35 different mutations were identified, of which seven were novel. Fasting blood glucose and HbA1c levels of the probands were ≤9.3 mmol/l and ≤56 mmol/mol (7.3%), respectively, and there was considerable variation in their BMI percentiles (0.4-96.2). In total, 25% of the probands had elevated homeostatic assessment of insulin resistance values, and 58.3% of these had evidence of concomitant Type 2 diabetes in their family. The HbA1c levels for adults were slightly higher, up to 61 mmol/mol (7.8%). The incidence of microvascular complications was low. Out of these 78 people with GCK-MODY and 40 additional family members with hyperglycaemia whose genetic status was unknown, only one had diabetic nephropathy. CONCLUSIONS The molecular and clinical features of GCK-MODY in Japanese people are similar to those of other ethnic populations; however, making a diagnosis of GCK-MODY was more challenging in patients with signs of insulin resistance.

Abstract
AIM To investigate the effect of catechins on vascular endothelial growth factor (VEGF) production and cyclooxygenase-2 (COX-2) expression in human dental pulp cells (HDPC) stimulated with bacteria-derived factors or pro-inflammatory cytokines. METHODOLOGY Morphologically fibroblastic cells established from explant cultures of healthy human dental pulp tissues were used as HDPC. HDPC pre-treated with catechins, epigallocatechin-3-gallate (EGCG) or epicatechin gallate (ECG), were exposed to lipopolysaccharide (LPS), peptidoglycan (PG), interlukin-1β (IL-1β) or tumour necrosis factor-α (TNF-α). VEGF production was examined by enzyme-linked immunosorbent assay, and COX-2 expression was assessed by immunoblot. RESULTS EGCG and ECG significantly reduced LPS- or PG-mediated VEGF production in the HDPC in a dose-dependent manner. EGCG also prevented IL-1β-mediated VEGF production. Although TNF-α did not enhance VEGF production in the dental pulp cells, treatment of 20 μg mL(-1) of EGCG decreased the level of VEGF. In addition, the catechins attenuated COX-2 expression induced by LPS and IL-1β. CONCLUSIONS The up-regulated VEGF and COX-2 expressions in the HDPC stimulated with these bacteria-derived factors or IL-1β were diminished by the treatment of EGCG and ECG. These findings suggest that the catechins may be beneficial as an anti-inflammatory tool of the treatment for pulpal inflammation.

Abstract
Abstract
Background: The St.Gallen consensus guideline recommends the sequential administration chemotherapy followed by of endocrine therapy as postoperative therapy for the higher risk ER-positive breast cancer patients based on results of a single study (Albain et al, Lancet 2009). In metastatic settings however, several trials conducted in the 1980's demonstrated that tumor response rates were higher when chemotherapy and tamoxifen were concomitantly administered, than when chemotherapy and tamoxifen administered were given sequentially. In the preoperative settings, pathological complete response (pCR) rate can be used a surrogate marker to predict event-free survival or overall survival in Luminal B(HER2-negative) breast cancer. We therefore designed a prospective randomized safety and efficacy trial in order to test a hypothesis that the concomitant administration of an aromatase inhibitor and chemotherapy improves pathological complete response(pCR) rate than chemotherapy alone in the preoperative setting.
Trial design: The trial is a prospective, multi-center, randomized comparison of chemotherapy alone versus concomitant chmo-endocrine therapy evaluating the efficacy in terms of pCR rate and safety in preoperative settings in patients with Luminal B (HER2-negative) breast cancer. 94 patients were to be accrued into this trial.
- arm A (control): 12 cycles of weekly paclitaxel(80mg/m2) followed by 4 cycles of every 3-week AC(Doxorubicine 60mg/m2, Cyclophosphamide 600mg/m2).
- arm B (experimental): The same chermotherapy as arm A and anastrozole in postmenopausal patients or anastrozole+leuprolerine in premenopansal patients.
Eligibility criteria: 1)Female patients with operable and histologically confirmed invasive breast cancer; 2)HER2-negative; 3)Either ER -positive or PgR-positive; 4)Either Ki67-LI> = 14% and NG> = 2 or NG = 3 regardless of Ki67-LI.
Endpoints : Primary endpoint is the pCR rate. Secondary endpoints are the clinical response rate(RECIST), the adverse events(CTC-AE ver.4.0), the breast conserving rate and the health related quality of life.
Statistical Considerations : The pCR rates in the control arm and the experimental arm are expected to be 10% and 25%, respectively. In order to show the superiority of the experimental arm with an alfa error at 5% and beta error at 20%, calculated number of patients needed were 96.
Present Accrual and Target Accrual: As of June 06, 2013, 18 patients were enrolled from 8 institutions.

Abstract
BACKGROUND Neuroimmunological disorders are involved in the pathogenesis of atopic dermatitis (AD), partly through enhanced sensory nerve-skin mast cell interaction. Cell adhesion molecule 1 (CADM1) is a mast-cell adhesion molecule that mediates the adhesion to, and communication with, sympathetic nerves. OBJECTIVES To investigate the role of mast cell CADM1 in the pathogenesis of AD, CADM1 expression levels by comparing between lesional and nonlesional skin mast cells of an AD mouse model, which was developed by repeated application of trinitrochlorobenzene, and to examine, in cocultures, how the alterations in CADM1 detected in lesional mast cells might affect the sensory nerve-mast cell interaction. METHODS AD-like lesional and nonlesional skin mast cells were collected separately by laser capture microdissection. CADM1 expression was examined by reverse transcription-polymerase chain reaction and CADM1 immunohistochemistry. In cocultures, adhesion between dorsal root ganglion (DRG) neurites and IC2 mast cells was analysed by loading a femtosecond laser-induced impulsive force on neurite-attendant IC2 cells, while cellular communication was monitored as the IC2 cellular response ([Ca(2+)]i increase) after nerve-specific stimulant-induced DRG activation. RESULTS AD-like lesional mast cells expressed three-fold more CADM1 transcripts than nonlesional cells. This was supported at the protein level, shown by immunohistochemistry. In coculture, CADM1 overexpression in IC2 cells strengthened DRG neurite-IC2 cell adhesion and doubled the population of IC2 cells responding to DRG activation. A function-blocking anti-CADM1 antibody abolished these effects in a dose-dependent manner. CONCLUSIONS Increased expression of CADM1 in mast cells appeared to be a cause of enhanced sensory nerve-mast cell interaction in a hapten-induced mouse model of AD.

Abstract
We herein report the case of a patient with a juxtaglomerular cell tumor (JCT). Dynamic enhanced computed tomography revealed a small nodule on the surface of the lower pole of the right kidney. Selective renal venous sampling showed an elevated level of plasma renin activity (PRA) in the right lower pole renal vein only. We performed right partial nephrectomy and diagnosed the patient with JCT. Making a diagnosis of JCT is often difficult due to the small size of the tumor and the lack of lateralization of the PRA on renal venous sampling. This case highlights the importance of performing selective renal venous sampling for the preoperative diagnosis of JCT.

Abstract
Abstract
Objectives: Optical mammography (O-MMG), which utilizes near-infrared light for the detection of abnormal breast tissue, can be a potentially useful and non-invasive tool for the screening of breast cancer patients. Here we report on the preliminary results of our clinical trial using a time-resolved O-MMG system developed by Hamamatsu Photonics (Hamamatsu, Japan). In our past examination, negative results included cases with mismatch for breast cup because of small breast, lesion outside of cup because of big breast, and bad positioning. So, size and shape of a gantry was improved (3 cup sizes; S, M and L cup). We reported the initial experience of the improved O-MMG systems.
Materials and Methods: In principle, the technique involves sequential irradiation of the breast tissue with a pulsed laser with a wavelength of 760, 800 and, 830nm, which is then detected by the variable capacity gantry at multiple sites after passing through the breast tissue. Measurement time has improved to about 7 minutes (a third of the conventional measurement time). The data are analyzed and tomographic images of the absorption coefficient of the breast are then reconstructed based on our tomographic reconstruction algorithm. Between October 2011 and May 2012, fifteen patients with breast cancer and one patient with fibroadenoma participated in the trial.
Results: In patients with breast cancer, S cup was used for one patient, M cup for 12 patients and L cup for two patients. Five patients after neo-adjuvant chemotherapy were excluded from the analysis. The lesions were depicted as an area of high hemoglobin concentration in 7 of 10 patients with cancer. One lesion of fibroadenoma was also identified as an area of high hemoglobin concentration.
Conclusion: Further examination with our new O-MMG systems will be of interest.

Abstract
We examined the effects of 5-Gy radiation on the expression of hypoxia-inducible factor-1α (HIF-1α) and the radiosensitivity of five human oral squamous cell carcinoma (OSCC) cell lines (SAS, Ca9-22, TT, BSC-OF and IS-FOM). In all of the cell lines, HIF-1α was expressed in mRNA, and radiation had no influence on gene transcription. The number of apoptotic cells increased 72 h after irradiation in cell lines SAS, Ca9-22 and TT cells, indicating low transcriptional levels of HIF-1α, and the levels of non-cleaved caspase-3, an executioner of apoptosis, and non-cleaved poly (adenosine diphosphate-ribose) polymerase (PARP), a marker of DNA damage early in apoptosis, decreased simultaneously. Conversely, radiation failed to induce apoptosis or to decrease expression of non-cleaved caspase-3 and PARP in cell lines BSC-OF and IS-FOM cells that expressed high levels of HIF-1α. BSC-OF and IS-FOM cells exhibited high migratory capacity. When CoCl(2) was present in the medium, HIF-1α expression increased along with the survival of Ca9-22 cells after radiation exposure. These results suggest that OSCC cells expressing high levels of HIF-1α are resistant to radiation. HIF-1α can be used to control the short-term radiosensitivity of cells.

Abstract
Abstract
Background: Activation of lipid metabolism is an early event of carcinogenesis and a central hallmark of many cancers including breast cancer. Recent findings argue that stearoyl CoA desaturase-1 (SCD1), a key regulator of the fatty acid (FA) composition and the endoplasmic reticulum resident enzyme that converts saturated FA (SFA) into monounsaturated FA (MUFA) is a novel regulator of carcinogenesis. The distinctive lipids composition of membrane in cancer cells and the biological functions of SCD1, however, still remain uncertain. Imaging mass spectrometry (IMS) is a mass spectrometry-based analyzing technique that enables visualization of the individual molecules without requiring antibodies. It allows comprehensive detection of a wide range of biomolecules, such as lipids. We attempted to visualize the localization of lipids in breast cancer by IMS for better understanding of cancer proliferation.
Materials and methods: 13 specimens were obtained from the primary breast cancer patients. All were Japanese woman and aged 41–86 years (mean 61.5y.o.). Only one patient received preoperative systematic therapy. 6 were estrogen receptor (ER) and/or progesterone receptor (PgR) positive and human epidermal growth factor receptor 2 (HER2) negative, 2 were ER and/or PgR positive and HER2 positive, 2 were both ER and PgR negative and HER2 positive and 2 were triple negative.
IMS: Samples were immediately chilled in liquid Hexan and stored at −80°. All specimens were sliced into 10 mm thin sections, mounted onto one indium-tin oxide-coated glass slides (Bruker Daltonics) and then sprayed by 2,5-Dihydroxybenzoic acid. Matrix assisted laser desorption ionization (MALDI) technique was used as a soft ionization method. We used time of flight (TOF)/TOF type instrument (Ultraflex, Bruker Daltonics) and all the spectrum were acquired automatically using Fleximaging software (Bruker Daltonics). Each spectral intensity at any mass-to-charge ratio (m/z) was measured at 16 regions of interest (ROI); 13 ROI were picked up from cancerous parts and 3 were from non-cancerous parts. Spectral intensities were compared and statistical analysis was performed by Mann Whitney test. The software was also used to create two-dimensional ion-density maps.
Results: In the cancerous parts of all the 13 specimens, two distinct peaks of the molecular ions were detected at m/z 798.5 and 810.5, which were not found in the non-cancerous parts. Median intensity of the molecular ions at m/z 798.5 and 810.5 were 38.9 and 3.18 in the cancerous part, while they were 0.84 and 1.02 in the non-cancerous part (p=0.010 and 0.015, respectively). Tandem mass spectrometry analysis for these two molecules revealed that they were two kinds of phosphatidylcholine (PC), PC (16:0/18:1) and PC (18:0/18:1). Localization of the individual PC was visualized by means of IMS, which showed that in cancerous part accumulation of PCs containing MUFA was more pronounced than those containing SFA only. Conclusion:
Two kinds of PC containing MUFA were found to highly accumulate in cancerous parts, which may suggest involvement of SCD1 in the membrane composition regulation and cancer proliferation. Further studies may thus be warranted to explore the relation between PC localization and the SCD1 expression.

Abstract
Objectives: To examine optical properties of breast cancer by time-resolved spectroscopy.
Materials and Methods: We irradiated a pulsed laser of 760, 800, and 830 nm wave-length lights at multiple sites of both breasts including the site just above the cancer and detected the light transmitted through the breast with TRS-20SH (Hamamatsu Photonics K.K.). Absorption coefficient (μa), reduced scattering coefficient (μs'), total hemoglobin (tHb), and oxygen saturation (SO2) of the breast were calculated by photon diffusion equation. The clinical trial started in January 2007. A total of one hundred nine breast cancer patients participated in the trial and written informed consent were obtained from all of the patients. Results: In 800 nm wave-length, absorption coefficient (μa) of breast cancer tissue was significantly high, compared with contra-lateral normal breast (cancer:0.0677± 0.0293, normal breast;0.0479± 0.0161, p<0.001).
The result was the same in 760, and 830 nm. There was no difference in reduced scattering coefficient (μs') between breast cancer tissue and contra-lateral normal breast (800 nm cancer:9.070±1.217, normal breast;9.348±1.243, p=0.10). The tHb of breast cancer tissue was significantly high, compared with normal breast (cancer:31.0± 14.7, normal breast;21.0±8.2, p<0.001). There was no difference in oxygen saturation (SO2) between breast cancer tissue and contra-lateral normal breast (cancer:72.8±4.1, normal breast;73.8±4.5, p=0.08).
Conclusion: Absorption coefficient (μa) and tHb increased in breast cancer, whereas reduced scattering coefficient (μs') did not.

Abstract
A 66-year-old man with Cushing's syndrome due to adrenocorticotropin-independent bilateral macronodular adrenocortical hyperplasia (AIMAH) was treated for 7 years with trilostane, a 3β-hydroxysteroid dehydrogenase inhibitor. Administration of trilostane reduced the serum cortisol level to around the upper limit of normal for 7 years, and symptoms of excessive glucocorticoid production (such as moon face and obesity) were gradually improved. On the other hand, the size of both adrenal glands gradually increased despite treatment with trilostane. Though trilostane therapy could not prevent adrenal growth, it did suppress cortisol secretion over the long term, so it might be a reasonable option for AIMAH in addition to adrenalectomy.

Abstract
The cell cycle of donor cells and recipient cytoplasts are important factors affecting development of nuclear transferred (NT) embryos. We previously showed that bovine NT embryos using pre-activated cytoplasts and early G1 cells had a high in vitro developmental rate (SSR, 2008, 41st Annual Meeting). The objective of the present study was to evaluate the effects of donor cell cycle (early G1 or G0 phase) and the timing of oocyte activation on fetal development of bovine NT embryos. Adult fibroblasts from ear skin tissue of Japanese black cattle were used as donor cells. The G0 phase cells were synchronized by serum-starvation, and the G1 phase cells were prepared from actively dividing M phase cells. NT embryo production was performed by 2 kinds of protocols as follows: 1) recipient oocytes were activated by Ca ionophore (CaI), followed with cycloheximide (CH) for 2 h, and fused with synchronized donor cells followed with cytochalasin D (CD) and CH for 1 h, then CH for 4 h (pre-activated), 2) unactivated oocytes were fused with synchronized donor cells and activation was performed by CaI 1 h after fusion, followed by with CD and CH 1 h, then CH for 4 h (post-activated). After activation treatments, NT embryos were cultured in IVD101 medium for 7 days. Then, blastocysts were transferred to recipient cows. Diagnosis of pregnancy was made by ultrasonography at days 30, 60, and 90 (Day 0 = the day of embryo transfer). As shown in Table 1, the blastocyst formation rate of the NT embryos derived from early G1 cells in the pre-activated group was higher than that from G0 cells in the post-activated group (36% v. 23%, P < 0.05). After embryo transfer, 29, 67, and 50% of recipient cows were pregnant at Day 30 in G0 post-, G1 post-, and G1 pre-activated groups, respectively. However, only 1 embryo (14%) of G0 post-activated group developed to term. In conclusion, bovine NT embryos using early G1 cells and pre-activated cytoplasts showed a high blastocyst formation rate, but the full-term development of bovine NT embryos could not be improved by using early G1 cells and pre-activated cytoplasts.

Abstract
BACKGROUND AND OBJECTIVE Because human gingival fibroblasts (HGFs) are the predominant cells in periodontal tissues, we hypothesized that HGFs are contributed to receptors for components of bacteria. In this study, we focused on expression and function of nucleotide binding oligomerization domain 2 (NOD2) in HGFs, which is a mammalian cytosolic pathogen recognition molecule. MATERIAL AND METHODS Expression of NOD2 in HGFs was examined by reverse transcriptase-polymerase chain reaction (RT-PCR) and flow cytometry. Production of interleukin (IL)-6, IL-8, cc chemokine ligand2, cxc chemokine ligand10 (CXCL10) and CXCL11 from HGFs was examined by enzyme-linked immunosorbent assay (ELISA). We used RT-PCR and immunohistochemistry to detect the NOD2 expression in human gingival tissues. RESULTS We found clear NOD2 expression in HGFs. Upon stimulation with NOD2 agonist, muramyldipeptide (MDP), production of proinflammatory cytokines was enhanced. Moreover, MDP-induced production of proinflammatory cytokines was inhibited in a different manner by mitogen-activated protein kinase inhibitors and phosphatidylinositol 3-kinase inhibitor. Furthermore, MDP enhanced CXCL10 and CXCL11 productions by tumor necrosis factor-alpha (TNF-alpha)- or interferon-gamma (IFN-gamma)-stimulated HGFs, although MDP alone did not induce these chemokines. TNF-alpha and IFN-gamma increased NOD2 expression in HGFs. In addition, we detected NOD2 expression in mononuclear cells and HGFs in periodontally diseased tissues. CONCLUSION These findings indicate that MDP which induces production of cytokines and chemokines from HGFs is related to the pathogenesis of periodontal disease.

Abstract
A 30-year-old woman had a history of prolactinoma and primary hyperparathyroidism. She was diagnosed as having multiple endocrine neoplasia type 1 with gastrinoma and liver metastases. Octreotide therapy was started and the serum gastrin level decreased immediately. Octreotide continued to suppress gastrin secretion over the next 7 years. The Ki67/MIB1 proliferation index of this tumor was only 0.5 % and somatostatin receptor (SSTR) 2 expression was very strong in both 2002 and 2009. This case suggests the importance of investigating the Ki67/MIB1 index and SSTR expression in patients with metastatic gastrinoma.

Abstract
We have reported that CXCL16, a recently discovered transmembrane chemokine, is expressed in human gingival fibroblasts (HGF). However, it is not known whether HGF express CXCR6, the receptor for CXCL16, or CXCL16 affects HGF biology. We have shown that HGF expressed CXCR6 by reverse transcription-polymerase chain reaction and flow cytometric analysis. Moreover, we elucidated that tumour necrosis factor (TNF)-alpha and cytosine-guanine dinucleotide (CpG) DNA (Toll-like receptor-9 ligand) treatment enhanced CXCR6 expression by HGF. Interleukin (IL)-4, IL-13 and CpG DNA up-regulated CXCR6 expression by TNF-alpha-stimulated HGF. On the other hand, IL-1beta and interferon-gamma inhibited CXCR6 expression on TNF-alpha-treated HGF. CXCL16 treatment induced HGF proliferation and phosphorylation of extracellular regulated kinase (ERK) and protein kinase B (AKT) in HGF. In conclusion, HGF expressed CXCR6 functionally, because CXCL16 induced HGF proliferation and ERK and AKT phosphorylation in HGF. These results indicate that CXCL16 may play an important role in the pathogenesis and remodelling in periodontally diseased tissues.

Abstract
A case of pulmonary alveolar microlithiasis occurring in an inbred family is presented. A genome-wide analysis of the patient's genomic DNA using a high-density single nucleotide polymorphism (SNP) array revealed a small intragenetic mutation at SLC34A2. The results suggest that the high-density SNP array has the power to identify a recessive disease gene(s) even in the analysis of only a single inbred patient.

Abstract
A 64-year-old woman had normal serum calcium and plasma parathyroid hormone levels, despite an extremely high plasma parathyroid hormone-related protein (PTHrP) level. She underwent medical screening at our hospital and several neck tumors were detected by ultrasonography. After surgical resection of these tumors, her plasma PTHrP level was normalized. Histological examination showed that the resected tumors were thyroid follicular adenomas, while immunohistochemistry revealed positive staining with a monoclonal antibody for PTHrP. This is a rare case of thyroid follicular adenoma producing PTHrP in a patient with a normal serum calcium level despite elevation of plasma PTHrP.

BACKGROUND AND OBJECTIVE It has been reported that T helper 2 (Th2) cells are related to exacerbation of periodontal disease. However, it is uncertain how the migration of Th2 cells is controlled. In this study, we examined the expression of CC chemokine ligand 17 (CCL17), which is a Th2 chemokine, in periodontal tissues. Moreover, we investigated the effects of cytokines and toll-like receptor (TLR) ligands on the production of CCL17 by human gingival fibroblasts (HGFs). MATERIAL AND METHODS We used immunohistochemistry and reverse transcriptase-polymerase chain reaction (RT-PCR) to detect CCL17 in periodontal tissues. HGFs were exposed to cytokines and TLR ligands. Expression of CCL17 was examined by RT-PCR and enzyme-linked immunosorbent assay. We used signal transduction inhibitors in some experiments. RESULTS Both CCL17 and its receptor, CC chemokine receptor 4 (CCR4), were expressed in diseased periodontal tissues. A combination of tumour necrosis factor alpha (TNF-alpha) and interleukin (IL)-4/IL-13 increased CCL17 expression. Moreover, treatment of HGFs with a low dose of interferon-gamma (IFN-gamma) in combination with TNF-alpha and IL-4 or IL-13 had synergistic effects on the production of CCL17, whereas a high dose of IFN-gamma inhibited CCL17 production. Furthermore, Escherichia coli (E. coli) lipopolysaccharide (TLR4 ligand) and Pam3CSK4 (TLR2 ligand) inhibited CCL17 production by TNF-alpha + IL-4-stimulated HGFs, while CpG DNA (TLR9 ligand) enhanced TNF-alpha + IL-4 induced-CCL17 production by HGFs. Furthermore, a c-Jun NH2 terminal kinase (JNK) inhibitor, a phosphatidylinositol-3-kinase (PI3K) inhibitor and a nuclear factor kappa B (NF-kappa B) inhibitor inhibited CCL17 production by HGFs. CONCLUSION These results suggest that the CCL17 produced by HGFs may be involved in the migration of Th2 cells into inflamed tissues, and provide evidence that CCL17 production is controlled by cytokines and TLR ligands in periodontal disease.
