Abstract
PURPOSE To compare the feasibilities and efficacies of the total extraperitoneal (TEP) technique and laparotomy for incarcerated obturator hernia repair. METHODS All study subjects were diagnosed with incarcerated obturator hernia, preoperatively and TEP was performed as for TEP groin hernia repair. The incarcerated intestine was retracted into the peritoneal cavity with the hernia sac. The obturator foramen was then covered with a rectangular mesh (9 × 13 cm), which also covered the internal inguinal ring, Hesselbach's triangle, and the femoral ring. Non-ischemia of the incarcerated bowel was confirmed laparoscopically. In patients undergoing laparotomy, the obturator foramen was closed by continuous sutures, and no prosthesis was used. We recorded the length of hospital stay, operative time, amount of intraoperative bleeding, and postoperative complications. RESULTS Twenty-two patients underwent obturator hernia repair in our hospital between January 2000 and December 2012, of whom 10 were treated with laparotomy and the remaining 12 via TEP. Three patients undergoing TEP were converted to laparotomy. The operation time was significantly longer in the conversion group compared with either the laparotomy or the TEP groups. There was no difference between the laparotomy and TEP groups regarding intraoperative bleeding. Patients who underwent TEP without conversion had a significantly shorter hospital stay than those who underwent laparotomy or required conversion. CONCLUSIONS TEP provides a suitable approach for incarcerated obturator hernia repair, with favorable results regarding hospital stay. TEP is a feasible, minimally invasive technique for the repair of incarcerated obturator hernias.

Abstract
Alterations in sleep patterns are often recognized as a premorbid symptom accompanied by affective disorders, particularly by major depression. However, the mechanism is rather complex, and differentiating its causalities from those of depression undergoes hardships. Indeed, depression is a complex disease. It has been clearly demonstrated that depressed patients display very characteristic changes in sleep architecture. Previous animal studies also demonstrated that several depression models, which had targeted elevated hypothalamic-pituitary-adrenocortical (HPA) axis, showed increased rapid eye movement (REM) sleep while insomniac sleep phenotype did not evidently appear. However, all stress hormones seem to be elevated in those models. Therefore, it has been difficult to determine which particular hormone in the HPA axis is primarily responsible for altered sleep in depression. In recent years, we have widely analyzed sleep characteristics of conditional transgenic mouse lines focusing on corticotropin-releasing hormone (CRH), the initial mediator of the HPA system, in which the levels of peripheral stress hormones are normal. Conditional CRH-overexpressing (COE) mice, especially those overexpress CRH limitedly within the forebrain including limbic structures (CRH-COE-Cam), dis- play enhanced REM sleep. Further, the higher occurrence of REM sleep in CRH-COE-Cam mice could be due to their hyper-cholinergic activity. REM sleep disinhibition observed in depressed patients similarly appears in animals which are genetically stress-vulnerable strain or chronically stressed, possibly due to enhanced action of limbic CRH. Indeed, REM sleep is a fragile vigilance state and closely connected with emotional control. Thus, depressive episodes may affect REM sleep earlier than nonREM sleep, and such altered REM sleep can be a state marker of depression.

Abstract
Analyses of nuclear emulsion detectors that can detect and identify charged particles or radiation as tracks have typically utilized optical microscope systems because the targets have lengths from several μm to more than 1000 μm. For recent new nuclear emulsion detectors that can detect tracks of submicron length or less, the current readout systems are insufficient due to their poor resolution. In this study, we developed a new system and method using an optical microscope system for rough candidate selection and the hard X-ray microscope system at SPring-8 for high-precision analysis with a resolution of better than 70 nm resolution. Furthermore, we demonstrated the analysis of submicron-length tracks with a matching efficiency of more than 99% and position accuracy of better than 5 μm. This system is now running semi-automatically.

Abstract
BACKGROUND AND PURPOSE Nociceptin/orphanin FQ (N/OFQ) peptide (NOP) receptor agonists display a promising analgesic profile in preclinical studies. However, supraspinal N/OFQ produced hyperalgesia in rodents and such effects have not been addressed in primates. Thus, the aim of this study was to investigate the effects of centrally administered ligands on regulating pain and itch in non-human primates. In particular, nociceptive thresholds affected by intracisternal N/OFQ were compared with those of morphine and substance P, known to provide analgesia and mediate hyperalgesia, respectively, in humans. EXPERIMENTAL APPROACH Intrathecal catheters were installed to allow intracisternal and lumbar intrathecal administration in awake and unanaesthetized rhesus monkeys. Nociceptive responses were measured using the warm water tail-withdrawal assay. Itch scratching responses were scored from videotapes recording behavioural activities of monkeys in their home cages. Antagonist studies were conducted to validate the receptor mechanisms underlying intracisternally elicited behavioural responses. KEY RESULTS Intracisternal morphine (100 nmol) elicited more head scratches than those after intrathecal morphine. Distinct dermatomal scratching locations between the two routes suggest a corresponding activation of supraspinal and spinal μ receptors. Unlike intracisternal substance P, which induced hyperalgesia, intracisternal N/OFQ (100 nmol) produced antinociceptive effects mediated by NOP receptors. Neither peptide increased scratching responses. CONCLUSIONS AND IMPLICATIONS Taken together, these results demonstrated differential actions of ligands in the primate supraspinal region in regulating pain and itch. This study not only improves scientific understanding of the N/OFQ-NOP receptor system in pain processing but also supports the therapeutic potential of NOP-related ligands as analgesics.

Abstract
Radiation protection issues on preparedness and response for a severe nuclear accident are discussed in this paper based on the experiences following the accident at Fukushima Daiichi nuclear power plant. The criteria for use in nuclear emergencies in the Japanese emergency preparedness guide were based on the recommendations of International Commission of Radiological Protection (ICRP) Publications 60 and 63. Although the decision-making process for implementing protective actions relied heavily on computer-based predictive models prior to the accident, urgent protective actions, such as evacuation and sheltering, were implemented effectively based on the plant conditions. As there were no recommendations and criteria for long-term protective actions in the emergency preparedness guide, the recommendations of ICRP Publications 103, 109, and 111 were taken into consideration in determining the temporary relocation of inhabitants of heavily contaminated areas. These recommendations were very useful in deciding the emergency protective actions to take in the early stages of the Fukushima accident. However, some suggestions have been made for improving emergency preparedness and response in the early stages of a severe nuclear accident.

Abstract
BACKGROUND AND PURPOSE The locus coeruleus (LC) is the principal nucleus containing the noradrenergic neurons and is a major endogenous source of pain modulation in the brain. Glial cell line-derived neurotrophic factor (GDNF), a well-established neurotrophic factor for noradrenergic neurons, is a major pain modulator in the spinal cord and primary sensory neurons. However, it is unknown whether GDNF is involved in pain modulation in the LC. EXPERIMENTAL APPROACH Rats with chronic constriction injury (CCI) of the left sciatic nerve were used as a model of neuropathic pain. GDNF was injected into the left LC of rats with CCI for 3 consecutive days and changes in mechanical allodynia and thermal hyperalgesia were assessed. The α2 -adrenoceptor antagonist yohimbine was injected intrathecally to assess the involvement of descending inhibition in GDNF-mediated analgesia. The MEK inhibitor U0126 was used to investigate whether the ERK signalling pathway plays a role in the analgesic effects of GDNF. KEY RESULTS Both mechanical allodynia and thermal hyperalgesia were attenuated 24 h after the first GDNF injection. GDNF increased the noradrenaline content in the dorsal spinal cord. The analgesic effects continued for at least 3 days after the last injection. Yohimbine abolished these effects of GDNF. The analgesic effects of GDNF were partly, but significantly, inhibited by prior injection of U0126 into the LC. CONCLUSIONS AND IMPLICATIONS GDNF injection into the LC exerts prolonged analgesic effects on neuropathic pain in rats by enhancing descending noradrenergic inhibition.

Abstract
The antitumor effects of a supramolecular substance, the [2] rotaxane (TRO-A0001), and its molecular mechanisms were investigated. TRO-A0001 suppressed the proliferation of cultured human Molt-3 acute lymphoblastic leukemia cells for 12-72 h in a dose-dependent manner. Based on flow cytometry, TRO-A0001 clearly induced apoptosis after 24 h. The mitochondrial membrane potential disappeared after treatment with 1.0 µM of TRO-A0001. Expression of the cleaved forms of capase-9 and caspase-3 was significantly increased in cells exposed to TRO-A0001, whereas the expression of XIAP, a type of inhibitor of apoptosis family, was decreased. These results suggest that [2] rotaxane TRO-A0001 may be a highly promising new antitumor medicine.

Abstract
The first determination of radii of point proton distribution (proton radii) of (12-17)B from charge-changing cross sections (σ(CC)) measurements at the FRS, GSI, Darmstadt is reported. The proton radii are deduced from a finite-range Glauber model analysis of the σ(CC). The radii show an increase from ¹³B to ¹⁷B and are consistent with predictions from the antisymmetrized molecular dynamics model for the neutron-rich nuclei. The measurements show the existence of a thick neutron surface with neutron-proton radius difference of 0.51(0.11) fm in ¹⁷B.

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”.

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.
