Abstract
Tooth agenesis is one of the most common congenital anomalies in humans. However, the etiology of tooth agenesis remains largely unclear, as well as evidence base useful for genetic counseling. Therefore, we estimated the prevalence and sibling recurrence risk, and investigated agenetic patterns systematically. Tooth agenesis was classified into two subtypes: hypodontia (one to five missing teeth) and oligodontia (six or more missing teeth). The prevalence of these two subtypes were 6.8% [95% confidence interval (CI): 6.1-7.7%] and 0.1% (95% CI: 0.04-0.3%), respectively, and sibling recurrence risk of these were 24.5% (95% CI: 13.8-38.3%) and 43.8% (95% CI: 26.4-62.3%), respectively. This result suggests that the severe phenotype, oligodontia, might be mostly transmitted in a dominant fashion. Using a simple statistical modeling approach, our data were found to be consistent with a bilateral symmetry model, meaning that there was equal probability of missing teeth from the right and left sides.

Abstract
BACKGROUND AND PURPOSE Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with no effective treatment. Fasudil hydrochloride (fasudil), a potent rho kinase (ROCK) inhibitor, is useful for the treatment of ischaemic diseases. In previous reports, fasudil improved pathology in mouse models of Alzheimer's disease and spinal muscular atrophy, but there is no evidence in that it can affect ALS. We therefore investigated its effects on experimental models of ALS. EXPERIMENTAL APPROACH In mice motor neuron (NSC34) cells, the neuroprotective effect of hydroxyfasudil (M3), an active metabolite of fasudil, and its mechanism were evaluated. Moreover, the effects of fasudil, 30 and 100 mg·kg(-1), administered via drinking water to mutant superoxide dismutase 1 (SOD1(G93A)) mice were tested by measuring motor performance, survival time and histological changes, and its mechanism investigated. KEY RESULTS M3 prevented motor neuron cell death induced by SOD1(G93A). Furthermore, M3 suppressed both the increase in ROCK activity and phosphorylated phosphatase and tensin homologue deleted on chromosome 10 (PTEN), and the reduction in phosphorylated Akt induced by SOD1(G93A). These effects of M3 were attenuated by treatment with a PI3K inhibitor (LY294002). Moreover, fasudil slowed disease progression, increased survival time and reduced motor neuron loss, in SOD1(G93A) mice. Fasudil also attenuated the increase in ROCK activity and PTEN, and the reduction in Akt in SOD1(G93A) mice. CONCLUSIONS AND IMPLICATIONS These findings indicate that fasudil may be effective at suppressing motor neuron degeneration and symptom progression in ALS. Hence, fasudil may have potential as a therapeutic agent for ALS treatment.

Abstract
Summary
Objectives: Standardization in the field of health informatics has increased its importance and global alliance for establishing interoperability and compatibility internationally. Standardization has been organized by standard development organizations (SDOs) such as ISO (International Organization for Standardization), CEN (European Committee for Standardization), IHE (Integrating the Healthcare Enterprise), and HL7 (Health Level 7), etc. This paper reports the status of these SDOs’ activities.
Methods: In this workshop, we reviewed the past activities and the current situation of standardization in health care informatics with the standard development organizations such as ISO, CEN, IHE, and HL7. Then we discussed the future direction of standardization in health informatics toward “future medicine” based on standardized technologies.
Results: We could share the status of each SDO through exchange of opinions in the workshop. Some WHO members joined our discussion to support this constructive activity.
Conclusion: At this meeting, the workshop speakers have been appointed as new members of the IMIA working groups of Standards in Health Care Informatics (WG16). We could reach to the conclusion that we collaborate for the international standardization in health informatics toward “future medicine”.

Effects of acivicin on growth, mycotoxin production and virulence of phytopathogenic fungi. Lett Appl Microbiol 2014; 59:377-83.

Abstract
Acivicin is an inhibitor of γ-glutamyl transpeptidase and glutamine amidotransferase. When grown on a synthetic minimal agar medium, acivicin strongly inhibited the growth of Magnaporthe oryzae and Alternaria brassicicola, and to a lesser extent, Botrytis cinerea. However, only partial or marginal growth inhibition was observed with regard to Fusarium sporotrichioides and Fusarium graminearum. The growth retardation caused by acivicin was significantly alleviated by cultivating the fungus on a nutrient-rich medium. The inhibition of M. oryzae growth caused by 1 μmol l(-1) of acivicin on minimal agar medium was subdued by the addition of specific single amino acids, including His, a branched-chain amino acid (Leu, Ile or Val), an aromatic amino acid (Trp, Tyr or Phe), Met or Gln, at a concentration of 0·4 mmol l(-1). Trichothecene production by F. graminearum in trichothecene-inducing liquid medium was reduced significantly in the presence of acivicin despite its inability to inhibit growth in the trichothecene-inducing liquid medium. Foliar application of conidia in the presence of acivicin reduced the severity of rice blast disease caused by M. oryzae. These results suggest the usefulness of this modified amino acid natural product to mitigate agricultural problems caused by some phytopathogenic fungi. Significance and impact of the study: Fusarium head blight or scab disease and rice blast, caused by Fusarium graminearum and Magnaporthe oryzae, respectively, are major diseases of cereal crops that cause a significant loss of yield and deterioration in the quality of the grain. The present study investigated the effects of acivicin, a glutamine amino acid analog, on the physiology of various phytopathogenic fungi. Application of acivicin to a fungal culture and conidial suspension reduced mycotoxin production by the wheat scab fungus and the severity of rice blast, respectively. These results suggest the possibility that acivicin may serve as a lead compound to develop agricultural chemicals for the control of some plant diseases.

Abstract
The Kunitz-type trypsin inhibitors, ETIa and ETIb, and chymotrypsin inhibitor ECI were isolated from the seeds of Erythrina variegata. The proteins were extracted from a defatted meal of seeds with 10 mM phosphate buffer, pH 7.2, containing 0.15 M NaCl, and purified by DEAE-cellulose and Q-Sepharose column chromatographies. The stoichiometry of trypsin inhibitors with trypsin was estimated to be 1:1, while that of chymotrypsin inhibitor with chymotrypsin was 1:2, judging from the titration patterns of their inhibitory activities. The complete amino acids of the two trypsin inhibitors were sequenced by protein chemical methods. The proteins ETIa and ETIb consist of 172 and 176 amino acid residues and have M(r) 19,242 and M(r) 19,783, respectively, and share 112 identical amino acid residues, which is 65% identity. They show structural features characteristic of the Kunitz-type trypsin inhibitor (i.e., identical residues at about 45% with soybean trypsin inhibitor STI). Furthermore, the trypsin inhibitors show a significant homology to the storage proteins, sporamin, in sweet potato and the taste-modifying protein, miraculin, in miracle fruit, having about 30% identical residues.

Abstract
BACKGROUND Recent study has demonstrated the important role of endothelial-mesenchymal interactions in 3-dimensional self-organization of immature progenitor populations with the use of mimicking of organogenesis. Here, we show that the same principle can be applicable to adult mature cells, ie, human adult hepatocytes (hAHs). METHODS We cultivated hAHs with fluorescence-labeled human mesenchymal cells (hMSCs) and human umbilical vein endothelial cells (HUVECs) in micro-well culture plates and observed them for 9 days. Fluorescence microscopy imaging analyses were performed to evaluate the internal structures of generated 3-dimensional tissues. Maintenance of in vitro protein production capacity was examined with the use of enzyme-linked immunosorbent assay (ELISA). RESULTS hAHs started to self-organize into 3-dimensional tissue with the use of coculturing with hMSCs and HUVECs. Live imaging analyses showed that endothelial cells started sprouting inside the generated tissues after 2 days of culture. ELISA showed that human albumin production capacity was improved with the use of coculture compared with hAHs-only culture after 9 days. CONCLUSIONS We demonstrated that 3-dimensional vascularized hepatic tissue could be generated from hAHs by reconstituting endothelial-mesenchymal interactions. Future studies are needed to evaluate the therapeutic potential of vascularized hepatic tissue transplantation, and this may pave a new way to establish a new transplantation modality as an alternative to hepatocyte transplantation.

Abstract
We aimed to examine the relationship between renal dysfunction and anaemia that may develop during combination therapy involving pegylated interferon, ribavirin and telaprevir (PEG-IFN/RBV/TVR) for the treatment of chronic hepatitis C. Sixty-eight patients with genotype 1b high viral loads were treated with PEG-IFN/RBV/TVR. Peg-IFN and RBV doses were administered according to body weight. TVR was prescribed at 2250 mg/day for 44 patients and at 1500 mg/day for 24 patients who had low haemoglobin level (<12 g/dL). When anaemia had developed, the RBV dose was decreased. The serum TVR concentration at day 8 was measured, and the serum RBV concentration was measured serially. The estimated glomerular filtration rate (eGFR) was estimated to assess renal function. At week 1, serum TVR concentration was not correlated with a decrease in eGFR; however, the TVR dose, on a weight basis (mg/kg), and eGFR were correlated (r = 0.2691; P = 0.0265). Moreover, there was a negative correlation between eGFR and RBV serum concentration (r = −0.3694; P = 0.0025), and the serum RBV concentration and decrease in the haemoglobin were significantly correlated from week 1 to week 8. In triple therapy, the TVR dose per weight is correlated with a decline in renal function. Thus, the serum concentration of RBV increases, with a concomitant decrease in haemoglobin. It is important to adjust the doses of TVR and RBV to avoid excessive serum RBV levels and the development of severe anaemia, to achieve a good clinical effect.

Abstract
AIM To obtain more information about the toxin/antitoxin (TA) systems in the Vibrio genus and also to examine their involvement in the induction of a viable but nonculturable (VBNC) state, we searched homologues of the Escherichia coli TA systems in the Vibrio parahaemolyticus genome. METHODS AND RESULTS We found that a gene cluster, vp1842/vp1843, in the V. parahaemolyticus genome database has homology to that encoding the E. coli TA proteins, DinJ/YafQ. Expression of the putative toxin gene vp1843 in E. coli cells strongly inhibited the cell growth, while coexpression with the putative antitoxin gene vp1842 neutralized this effect. Mutational analysis identified Lys37 and Pro45 in the gene product VP1843 of vp1843 as crucial residues for the growth retardation of E. coli cells. VP1843, unlike the E. coli toxin YafQ, has no protein synthesis inhibitory activity, and that instead the expression of vp1843 in E. coli caused morphological change of the cells. CONCLUSIONS The gene cluster vp1842/vp1843 encodes the V. parahaemolyticus TA system; VP1843 inhibits cell growth, whereas VP1842 serves as an antitoxin by forming a stable complex with VP1843. SIGNIFICANCE AND IMPACT OF THE STUDY The putative toxin, VP1843, may be involved in the induction of the VBNC state in V. parahaemolyticus by inhibiting cell division.

Abstract
Intrameniscal cysts begin with the flow of synovial fluid from a meniscal tear in one direction, enlarging probably as a result of an on-and-off valve mechanism of the tear flap. The current available literature focuses primarily on the necessity for surgery, however a large meniscus resection to remove cysts may place an additional burden on menisci, leading ultimately to knee joint degenerative changes. In this article, we present a rare case of intrameniscal cysts with an isolated horizontal meniscal tear in an adolescent, and describe a new arthroscopic procedure for treating this type of intrameniscal cyst. We performed arthroscopic partial release of the meniscal tear check-valve mechanism, preventing further intrameniscal cyst expansion. The patient's clinical symptoms improved, and this procedure may also be useful in treating intrameniscal cysts with an isolated horizontal meniscal tear and can be considered as an option to preserve meniscal function and minimize degenerative arthritis in young athletes.

Abstract
A subcutaneous tumour was identified in the malar region of a 14-year-old neutered female mixed breed dog. The dog was humanely destroyed and necropsy examination was performed. The tumour did not invade neighbouring tissues and no metastasis was found. Microscopically, the tumour showed a range of features including the presence of multinucleated giant cells, chondrocyte differentiation and cystic or slit-like structures. All of these features are consistent with previously reported descriptions of synovial sarcomas in dogs. Mesenchymal cells accounted for the majority of the tumour, but cytokeratin-positive epithelioid components were also confirmed by immunohistochemistry. The tumour was diagnosed as a biphasic type of synovial sarcoma. Synovial sarcoma in man may develop in tissues unrelated to joints and this is the first report of a non-joint synovial sarcoma in a dog.

Abstract
PURPOSE The prognosis of patients with esophageal cancer remains poor, and the classification of tumor node metastasis has proven insufficient to predict patient prognosis. Therefore, novel predictive markers of esophageal cancer prognosis are needed. Notch receptors and their ligands have been reported to be upregulated in cervical, lung, colon, renal, and pancreatic cancers, but NOTCH1 expression has not been studied in esophageal cancer. METHODS Expression of NOTCH1 was quantified by real-time reverse transcription-polymerase chain reaction in 55 primary esophageal squamous cell carcinomas (ESCCs) and their paired normal esophageal mucosa. We then examined the correlations between NOTCH1 expression, clinicopathological factors, and prognosis in patients with ESCC. RESULTS The probability of overall survival was significantly lower for patients with high NOTCH1 expression (p = 0.0028; log-rank test). Overexpression of NOTCH1 was identified as a significant and independent prognostic factor (p = 0.0061) in patients who had undergone surgical treatment for ESCCs. The hazard ratio for predicting early death was 4.298 (95% confidence interval 1.515-12.195) for high versus low NOTCH1 expression. CONCLUSIONS Our data indicate that NOTCH1 may be a candidate molecular prognostic marker and a molecular target for the development of an effective therapeutic intervention for patients with ESCC.

Abstract
AIMS To compare the efficacy and safety of these two agents and the impact on surrogate markers related to diabetic complications in Japanese type 2 diabetic patients. METHODS In a multicenter, open-label trial, 130 patients whose diabetes had been inadequately controlled (HbA1c, 6.9-9.5%) with metformin and/or sulphonylurea were randomly assigned to a sitagliptin group (50 mg/day) or a pioglitazone group (15 mg/day) and were followed up for 24 weeks. At 16 weeks, if the patient's HbA1c level was ≥6.5%, the dose of sitagliptin or pioglitazone was increased up to 100 or 30 mg/day, respectively. Main outcome measure was the difference in the mean changes in the HbA1c level from baseline at 24 weeks between these two groups. RESULTS Of the 130 patients who were enrolled, 115 subjects (sitagliptin group: 58 patients, pioglitazone group: 57 patients) completed this trial. At 0 weeks, the mean HbA1c level was 7.47 ± 0.66% in the sitagliptin group and 7.40 ± 0.61% in the pioglitazone group. At 24 weeks, the mean changes in the HbA1c level from baseline were -0.86 ± 0.63% versus -0.58 ± 0.68% (p = 0.024). Hypoglycaemia (2 patients, 3.4% vs. 2 patients, 3.5%), gastrointestinal symptoms (3 patients, 5.2% vs. 1 patient, 1.8%) and pretibial oedema (0 patients, 0% vs. 39 patients, 68.4%, p < 0.001) were observed for 24 weeks. CONCLUSIONS Sitagliptin was not only more tolerable, but also more effective than pioglitazone in Japanese type 2 diabetic patients who had been treated with metformin and/or sulphonylurea.

Abstract
We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x-ray free-electron laser facility, SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xe(n+) with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n≥24) are produced via five-photon absorption, evidencing the occurrence of multiphoton absorption involving deep inner shells. A newly developed theoretical model, which shows good agreement with the experiment, elucidates the complex pathways of sequential electronic decay cascades accessible in heavy atoms. The present study of heavy-atom ionization dynamics in high-intensity hard-x-ray pulses makes a step forward towards molecular structure determination with x-ray free-electron lasers.

Abstract
The aim of this study was to characterize immunohistochemically 18 cases of canine haemangiopericytoma (CHP) using two new candidate markers for pericytes, tumour endothelial marker (TEM)-1 and new glue (NG)-2, as well as the conventional mesenchymal cellular markers, vimentin, α-smooth muscle actin (α-SMA), desmin and von Willebrand factor (vWF). Because pericytes may have the same origin as endothelial or smooth muscle cells or the same differentiation potential as myofibroblasts, 17 cases of leiomyosarcoma (LMS), 20 cases of haemangiosarcoma (HS) and three cases of myofibroblastic sarcoma (MFS) were also examined. Expression of TEM-1 by >10% of the neoplastic population was observed in 94.4% (17/18) of haemangiopericytomas, 23.5% (4/17) of LMSs, 30.0% (6/20) of HSs and 66.7% (2/3) of MFSs. NG-2 expression by >10% of the neoplastic population was observed in 16.7% (3/18) of haemangiopericytomas, 52.9% (9/17) of LMSs, 0% (0/20) of HSs and 33.3% (1/3) of MFSs. Vimentin was expressed by all of tumours. In haemangiopericytoma, the incidence of positive immunoreactivity in >10% of the neoplastic population was 5.6% (1/18) for both α-SMA and desmin and 0% (0/18) for vWF. Considering the phenotypic features of cells expressing TEM-1, CHPs are thought to originate from immature vascular mural cells sharing their phenotype with myofibroblasts. NG-2 expression may be a phenotype of smooth muscle cells rather than pericytes in dogs.

Abstract
Gender-related risk factors in the survival of transplanted teeth with complete root formation have not yet been identified. The purpose of this study was to investigate gender differences in tooth autotransplantation at dental clinics. We asked participating dentists to provide information on transplantations they had undertaken from 1 January 1990 to 1931 December 2010. The data were screened to exclude patients who underwent more than one transplantation, smokers or those whose smoking habits were unknown, patients under 30 or who were 70 years old and over, cases where the transplanted teeth had incomplete root formation or multiple roots and those with fewer than 20 present teeth post-operation. We analysed 73 teeth of 73 males (mean age, 47.2 years) and 106 teeth of 106 females (mean age, 45.3 years) in this study. The cumulative survival rate and mean survival time were calculated using the Kaplan-Meier method. The cumulative survival rate for males was 88.3% at the 5-year mark, 64.8% at 10 years and 48.6% at 15 years; for females, it was 97.2% at the 5-year mark, 85.9% at 10 years and 85.9% at 15 years. A log-rank test indicated the difference between males and females to be significant (P = 0.011). There was also a significant difference in the main causes for the loss of transplanted teeth: males lost more transplanted teeth due to attachment loss than females (P < 0.05). These results indicate that males require more attention during the autotransplantation process, particularly at the stage of pre-operation evaluation and that of follow-up maintenance.

Abstract
A down-flow hanging sponge reactor, constructed by connecting three identical units in series, was applied to the treatment of artificial wastewater containing phenol and ammonia under high salinity conditions (10.9 g-Cl(-)/L). The theoretical hydraulic retention time (HRT) of each unit was 4 h (total HRT = 12 h). To enhance denitrification by effluent recirculation, the effluent recirculation ratio was increased in increments ranging from 0.0 to 2.0. The concentration of total ammonia nitrogen (TAN), NO2-N, and NO3-N in the final effluent as a proportion of the TAN in the influent was determined to calculate the unrecovered, or denitrification, proportion. The denitrification proportion of the reactor was equivalent to 19.1 ± 14.1% with no effluent recirculation; however, this was increased to 58.6 ± 6.2% when the effluent recirculation ratio was increased to 1.5. Further increasing the effluent recirculation ratio to 2.0 resulted in a decrease in the denitrification proportion to 50.9 ± 9.3%. Activity assays of nitrification and denitrification, as well as 16S rRNA gene sequence analysis, revealed that denitrification occurred primarily in the upper sections of the reactor, while nitrification increased in the lower sections of the reactor. Gene sequence analysis revealed that denitrification by Azoarcus-like species using phenol as an electron donor was dominant.

Abstract
A 3-year-old female shih tzu was presented with a white to dark red mass arising from the gingiva. Because of the rapid and invasive growth of the mass, the dog was humanely destroyed. Microscopically, round to polygonal anaplastic cells with strongly eosinophilic cytoplasm grew in an alveolar pattern separated by fibrous stroma. Mitotic figures were numerous. Multinucleated cells and 'strap cells' were observed, but cross striation and glycogen accumulation were absent. Immunohistochemically, the tumour cells were positive for vimentin, desmin, muscle-specific actin and MyoD1, and a small number of tumour cells were positive for α-smooth muscle actin (α-SMA). Based on the morphological and immunohistochemical features, the gingival mass was diagnosed as alveolar rhabdomyosarcoma accompanied by α-SMA-positive immature myogenic cells.

Abstract
Changes in sexual bother (SB) following radical prostatectomy (RP) negatively affect health-related quality of life (HRQoL) of prostate cancer survivors. However, post-operative SB tends to be neglected whereas sexual function (SF) is thoroughly assessed in clinical practice and few studies have focused on and evaluated patients' SB. We retrospectively reviewed 2 345 consecutive patients who underwent RP between 2001 and 2009 at a single institution. SF and SB were assessed using Expanded Prostate Cancer Index Composite (EPIC) questionnaires. We stratified our cohort by SB recovery and post-operative SF status, including a subset of men who recovered SB despite persistent post-RP sexual dysfunction. Multivariable logistic regression analyses were conducted to identify factors for men who have SB recovery. Of 319 eligible patients, 133 (41.7%) recovered their SB at a mean of 20 months after RP. Among the 133 men who demonstrated SB recovery, 109 had post-operative sexual dysfunction. Patients with SB recovery despite post-RP sexual dysfunction were more likely to be old (p = 0.004), to have higher clinical T stage (p < 0.001), to have more non-nerve-sparing RP (p < 0.001), to have lower pre-operative EPIC-SF/SB scores (p < 0.001), to have more extracapsular extension (p = 0.031) and to be PDE5i non-users after surgery (p < 0.001). In multivariable analysis, predictors for this subset were lower comorbidity (OR 0.62, p = 0.043), higher clinical cancer stage (OR 2.35, p = 0.026), worse pre-operative SF (OR 0.98, p = 0.010), SB (OR 0.98, p < 0.010) and no PDE5i use (OR 0.37, p = 0.002); age was not related (OR 0.99, p = 0.555). As SB can influence patients' overall HRQoL, expectations of SB recovery should be provided to patients in the same way that SF recovery is presented. This study may help clinicians to discuss SB with patients and assess their potential for SB recovery following RP.

Abstract
Introduction. Amniotic membrane contains a multipotential stem cell population and is expected to possess the machinery to regulate immunological reactions. We investigated the safety and efficacy of allogeneic amniotic membrane-derived mesenchymal stromal cell (AMSC) transplantation in a porcine model of chronic myocardial ischemia as a preclinical trial. Methods. Porcine AMSCs were isolated from amniotic membranes obtained by cesarean section just before delivery and were cultured to increase their numbers before transplantation. Chronic myocardial ischemia was induced by implantation of an ameroid constrictor around the left circumflex coronary artery. Four weeks after ischemia induction, nine swine were assigned to undergo either allogeneic AMSC transplantation or normal saline injection. Functional analysis was performed by echocardiography, and histological examinations were carried out by immunohistochemistry 4 weeks after AMSC transplantation. Results. Echocardiography demonstrated that left ventricular ejection fraction was significantly improved and left ventricular dilatation was well attenuated 4 weeks after AMSC transplantation. Histological assessment showed a significant reduction in percentage of fibrosis in the AMSC transplantation group. Injected allogeneic green fluorescent protein (GFP)-expressing AMSCs were identified in the immunocompetent host heart without the use of any immunosuppressants 4 weeks after transplantation. Immunohistochemistry revealed that GFP colocalized with cardiac troponin T and cardiac troponin I. Conclusions. We have demonstrated that allogeneic AMSC transplantation produced histological and functional improvement in the impaired myocardium in a porcine model of chronic myocardial ischemia. The transplanted allogeneic AMSCs survived without the use of any immunosuppressants and gained cardiac phenotype through either their transdifferentiation or cell fusion.
