Abstract
We applied a new technique for quantitative linear range shift using in-source collision-induced dissociation (CID) to complex biological fluids to demonstrate its utility. The technique was used in a simultaneous quantitative determination method of 5-fluorouracil (5-FU), an anticancer drug for various solid tumors, and its metabolites in human plasma by liquid chromatography-electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS). To control adverse effects after administration of 5-FU, it is important to monitor the plasma concentration of 5-FU and its metabolites; however, no simultaneous determination method has yet been reported because of vastly different physical and chemical properties of compounds. We developed a new analytical method for simultaneously determining 5-FU and its metabolites in human plasma by LC/ESI-MS/MS coupled with the technique for quantitative linear range shift using in-source CID. Hydrophilic interaction liquid chromatography using a stationary phase with zwitterionic functional groups, phosphorylcholine, was suitable for separation of 5-FU from its nucleoside and interfering endogenous materials. The addition of glycerin into acetonitrile-rich eluent after LC separation improved the ESI-MS response of high polar analytes. Based on the validation results, linear range shifts by in-source CID is the reliable technique even with complex biological samples such as plasma. Copyright © 2016 John Wiley & Sons Ltd.

Abstract
AIM The rate of extension of proctitis in Western countries has been reported, but no data regarding long-term follow-up have been described for the Japanese population. Additionally, patients with long-standing or extensive ulcerative colitis have an increased risk for developing colorectal cancer. This study evaluated both the rate of extension of the disease and the development of neoplasia among patients with an initial diagnosis of ulcerative proctitis. METHOD We retrospectively investigated the medical charts of patients with proctitis from 1979 to 2014. The primary focus of this research was the extension of the inflammatory area. The secondary focus included risk factors for disease extension and the development of neoplasia. RESULTS Sixty-six patients satisfied the inclusion criteria. Proximal extension of the disease occurred in 34 patients: 19 patients had left-sided colitis and 15 had pancolitis. According to a multivariate analysis, disease extension was significantly higher in patients with disease onset before 25 years of age (P-value = 0.043). The cumulative rates of disease extension at 10 and 20 years were 33.8% and 52.2%, respectively. Three patients were diagnosed with dysplasia during follow-up, all of whom experienced disease extension before the development of dysplasia. CONCLUSION The rate of extension of ulcerative colitis in the Japanese population was comparable to that in Western countries. A younger age of disease onset was associated with disease extension. Extension of proctitis may be associated with an increased risk of colorectal cancer.

Abstract
Postural stability degrades with age, threating the health and life quality of the older adults. One Leg Stance (OLS) is one of the standard and commonly adopted assessments for postural stability, and the postural sway in OLS has been demonstrated to be related with age. The propagation of postural sway between body segments could be a hint to the underlying mechanism of balance control. However, it is not yet fully understood. Therefore, the aim of this paper was to study the angular sways and their propagation of the head, trunk, and lower limb in healthy older adults. A cross-correlation of the normalized angular speeds was performed and the experiment with 68 older adults was conducted. The results showed that the head, hip and ankle joints affected the transfer of angular sway with a relatively lower correlation and longer latency.

Abstract
Background Maternal uniparental disomy 14 (UPD(14)mat) is an imprinting disorder. It is a rare disease, but there is the possibility that more undiagnosed patients might exist because the clinical features of UPD(14)mat resemble those of the Prader-Willi syndrome or other congenital diseases. We performed anesthetic management for an 8-year-old girl with UPD(14)mat. Case presentations She was admitted to undergo correction surgery due to symptomatic scoliosis. Preoperative examination revealed that she had a restricted mouth opening and retrognathia, as well as some typical characteristics of UPD(14)mat, such as small hands, growth retardation, and precocious puberty. We induced general anesthesia using sevoflurane without any problems. However, the tracheal intubation was difficult because of the restricted mouth opening. We used the McGRATHR MAC videolaryngoscope to overcome this problem. Conclusions We speculate that the craniofacial deformity in case of UPD(14)mat patients may lead to difficulty in tracheal intubation.

Abstract
We report measurements of the physical properties and electronic structure of the hexagonal compounds Yb2Ni12Pn7 (Pn = P, As) by measuring the electrical resistivity, magnetization, specific heat and partial fluorescence yield x-ray absorption spectroscopy (PFY-XAS). These demonstrate a crossover upon reducing the unit cell volume, from an intermediate valence state in Yb2Ni12As7 to a heavy-fermion paramagnetic state in Yb2Ni12P7, where the Yb is nearly trivalent. Application of pressure to Yb2Ni12P7 suppresses TFL, the temperature below which Fermi liquid behavior is recovered, suggesting the presence of a quantum critical point (QCP) under pressure. However, while there is little change in the Yb valence of Yb2Ni12P7 up to 30 GPa, there is a strong increase for Yb2Ni12As7 under pressure, before a near constant value is reached. These results indicate that any magnetic QCP in this system is well separated from strong valence fluctuations. The pressure dependence of the valence and lattice parameters of Yb2Ni12As7 are compared and at 1 GPa, there is an anomaly in the unit cell volume as well as a change in the slope of the Yb valence, indicating a correlation between structural and electronic changes.

Abstract
The increasing age of the world population is posing new challenges to our society, such as how to keep this aging population healthy and active despite of the age. In recent years, there has been a lot of interest for gait analysis for rehabilitation purposes as well as for performance assessment of this aging population. While current systems work well, they still have several limitations. Cost, need for specialized personnel, need to be used in a research center, and sporadic measurement prevent these systems from being widely used. The authors propose the use of extremely miniaturized, portable measurement systems, which can be worn by the users during their everyday life, and can monitor their gait over a long timespan. This paper presents the preliminary experiments with such a system.

Abstract
ABSTRACT
Fresh NR was adopted to prepare rubber with a nanomatrix structure. The nanomatrix structure was formed by graft-copolymerization of styrene onto deproteinized fresh NR (fresh DPNR) in the latex stage using tert-butyl hydroperoxide/tetraethylenepentamine as an initiator. Graft-copolymer consisting of fresh DPNR and polystyrene (fresh DPNR-graft-PS) was characterized by 1H-NMR spectroscopy and transmission electron microscopy. Under a suitable condition of the graft-copolymerization, conversion and grafting efficiency of styrene was 98 and 80 mol%, respectively. Morphology of fresh DPNR-graft-PS was observed by transmission electron microscopy. The rubber particles of about 1 μm in diameter were found to be dispersed in polystyrene matrix of 10–30 nm in thickness. Tensile properties of fresh DPNR were dramatically improved by forming the nanomatrix structure, compared with DPNR.

Abstract
Psychiatric manifestations of systemic lupus erythematosus (SLE) that are commonly preceded by organic syndromes include confusional states, anxiety disorder, cognitive dysfunction, mood disorder and psychosis. A 35-year-old woman was admitted to hospital with a relapse of SLE. Laboratory data were exacerbated, with some physical symptoms, and her primary psychiatric symptom was mania. The symptoms were reduced by treatment with prednisolone, methylprednisolone and aripiprazole. Magnetic resonance imaging and single-photon emission computed tomography (SPECT) using 123I-IMP was then performed and analyzed with three-dimensional stereotactic surface projection. This case emphasizes that SLE can commence with organic syndromes and relapse with predominantly psychiatric symptoms, and that the treatment efficacy may be confirmed using a follow-up of SPECT.

Abstract
Background Elpamotide is an HLA-A*24:02-restricted epitope peptide of vascular endothelial growth factor receptor 2 (VEGFR-2) and induces cytotoxic T lymphocytes (CTLs) against VEGFR-2/KDR. Given the high expression of VEGFR-2 in biliary tract cancer, combination chemoimmunotherapy with elpamotide and gemcitabine holds promise as a new therapy. Patients and Methods Patients with unresectable advanced or recurrent biliary tract cancer were included in this single-arm phase II trial, with the primary endpoint of overall survival. Survival analysis was performed in comparison with historical control data. The patients concurrently received gemcitabine once a week for 3 weeks (the fourth week was skipped) and elpamotide once a week for 4 weeks. Results Fifty-five patients were registered, of which 54 received the regimen and were included in the full analysis set as well as the safety analysis set. Median survival was 10.1 months, which was longer than the historical control, and the 1-year survival rate was 44.4 %. Of these patients, injection site reactions were observed in 64.8 %, in whom median survival was significantly longer (14.8 months) compared to those with no injection site reactions (5.7 months). The response rate was 18.5 %, and all who responded exhibited injection site reactions. Serious adverse reactions were observed in five patients (9 %), and there were no treatment-related deaths. Conclusion Gemcitabine and elpamotide combination therapy was tolerable and had a moderate antitumor effect. For future development of therapies, it will be necessary to optimize the target population for which therapeutic effects could be expected.

Abstract
OBJECTIVE To understand the role, safety and efficacy of flexible ureterorenoscopy and lasertripsy (FURSL) for paediatric renal stones. MATERIAL AND METHODS A systematic review was conducted using studies identified by a literature search between January 1990 and March 2014. All English language articles reporting on a minimum of five patients≤18-years old, treated with flexible ureteroscopy and lasertripsy for stone disease were included. RESULTS A total of six studies (282 patients) were reported, with a mean age of 7.3 years (range 0.25-17 years). The stone sizes ranged from 1 to 30 mm. The mean stone-free rate across the three studies was 85.5% (range 58.0-93.0%) after initial ureteroscopy, with a postoperative stent inserted in 81.8% (range 66.7-98.0%). There were a total of 35 complications (12.4%), with the most severe complication being a Clavien class III (five ureteral injuries, one urinoma). There were no deaths in any of the studies. CONCLUSION The present review shows that FURSL for management of renal calculi in the paediatric population is an effective and safe procedure. To ensure that outcomes keep on improving, these procedures should be undertaken by experienced surgeons who are familiar with the difficulties encountered in the paediatric population.

Abstract
Pressure dependence of the Ce valence in CeCu(2)Ge(2) has been measured up to 24 GPa at 300 K and to 17 GPa at 18-20 K using x-ray absorption spectroscopy in the partial fluorescence yield. A smooth increase of the Ce valence with pressure is observed across the two superconducting (SC) regions without any noticeable irregularity. The chemical pressure dependence of the Ce valence was also measured in Ce(Cu(1-x)Ni(x))(2)Si(2) at 20 K. A very weak, monotonic increase of the valence with x was observed, without any significant change in the two SC regions. Within experimental uncertainties, our results show no evidence for the valence transition with an abrupt change in the valence state near the SC II region, challenging the valence-fluctuation mediated superconductivity model in these compounds at high pressure and low temperature.

Abstract
Background: Pancreatic cancer has a poor prognosis because of its high refractoriness to chemotherapy and tumour recurrence, and these properties have been attributed to cancer stem cells (CSCs). MicroRNA (miRNA) regulates various molecular mechanisms of cancer progression associated with CSCs. This study aimed to identify the candidate miRNA and to characterise the clinical significance. Methods: We established gemcitabine-resistant Panc1 cells, and induced CSC-like properties through sphere formation. Candidate miRNAs were selected through microarray analysis. The overexpression and knockdown experiments were performed by evaluating the in vitro cell growth and in vivo tumourigenicity. The expression was studied in 24 pancreatic cancer samples after laser captured microdissection and by immunohistochemical staining. Results: The in vitro drug sensitivity of pancreatic cancer cells was altered according to the miR-1246 expression via CCNG2. In vivo, we found that miR-1246 could increase tumour-initiating potential and induced drug resistance. A high expression level of miR-1246 was correlated with a worse prognosis and CCNG2 expression was significantly lower in those patients. Conclusions: miR-1246 expression was associated with chemoresistance and CSC-like properties via CCNG2, and could predict worse prognosis in pancreatic cancer patients.

Abstract
Congenital myasthenic syndromes (CMS) are heterogeneous disorders of neurotransmission caused by genetic mutations of neuromuscular junction molecules. We report anesthetic management of a CMS patient who was a 14-year-old boy with endplate acetylcholinesterase deficiency. The patient used noninvasive positive pressure ventilation (NPPV) at night. He underwent a corrective maneuver for severe scoliosis under general anesthesia. General anesthesia was maintained using propofol and remifentanil. Intraoperative mechanical ventilation remained stable. Extubation was performed on the next day and NPPV was started. Several hours later, he complained of a stomachache and intense abdominal bloating. Computed tomography revealed a massive amount of air in the stomach and intestine. He recovered from abdominal bloating the next day without treatment for decompression. Lung-thoracic compliance has been reported to decrease immediately after a corrective maneuver for scoliosis patients. In our case, we suspected a relative increase of abdominal compliance to lung-thoracic compliance as a cause of intense abdominal bloating by air injection from NPPV with his daily setting. In CMS, symptoms, therapy and contraindicated drugs vary according to the location of dysfunction. Therefore, anesthetic management according to each genotype should be designed to avoid drugs that could either trigger or worsen CMS. Intensive respiratory care is advisable after surgery.

Abstract
The form and timing of the local recurrence of lung cancer can be unpredictable and unexpected. Pseudomesotheliomatous adenocarcinoma is a rare tumor that mimics malignant pleural mesothelioma both clinically and pathologically. Distinguishing pseudomesotheliomatous adenocarcinoma from malignant pleural mesothelioma on the basis of clinical findings can be difficult; therefore, a biopsy is usually required for diagnosis. Here we report on a 73-year-old Japanese man who presented with extensive dissemination along the pleural surfaces and clinical findings similar to those of pseudomesotheliomatous lung cancer 10 years after undergoing left upper lobectomy for lung adenocarcinoma. This report provides information that will help physicians establish an accurate diagnosis in similar cases.

Abstract
The patient, a 56-year-old woman, was found during routine checkup to have a disorder of hepatic function. Abdominal ultrasonography showed an ill-defined hypoechoic mass in the head and body of the pancreas; however, no blood-flow signal was observed within the tumor on Doppler ultrasonography. Abdominal computed tomography showed a low-density area in the arterial and portal venous phases. The lesion was visualized as an area of low signal intensity on both T1- and T2-weighted magnetic resonance images, whereas fluorodeoxyglucose positron emission tomography showed fluorodeoxyglucose accumulation in the tumor. Although a preoperative diagnosis was difficult to make, a rapid cytologic examination revealed evidence of a pancreatic endocrine tumor, and subtotal stomach-preserving pancreaticoduodenectomy with portal vein resection was performed. Histopathological examination showed tumor cell nests scattered in abundant fibrotic tissue; the tumor cells had proliferated in a cord-like fashion and showed immunostaining for chromogranin A. Staining for fibroblast activation protein α was seen in the fibroblastic cells contained within the fibrous stroma surrounding the tumor cell nests, whereas both the fibroblastic cells in the tumor and those in the stroma showed a high rate of staining for thrombospondin. We presume that tumor-associated fibroblasts were involved in the fibrosis of the tumor stroma.

Abstract
We have proposed and developed a new type of electroabsorption modulator (EAM) that employs both optical absorption and interferometric extinction. The EAM operates at a record low voltage of 0.2 V at 25.8-Gbit/s modulation, which can reduce optical transmitter power consumption and allows the adoption of cost-effective CMOS drivers.

Abstract
Introduction Growing teratoma syndrome is a rare occurrence with an ovarian tumor. Anesthesia has been reported to be difficult in cases of growing teratoma syndrome of the cystic type due to the pressure exerted by the tumor. However, there have been no similar reports with the solid mass type. Here, we report our experience of anesthesia in a case of growing teratoma syndrome of the solid type. Case presentation The patient was a 30-year-old Japanese woman who had been diagnosed with an ovarian immature teratoma at age 12 and had undergone surgery and chemotherapy. However, she dropped out of treatment. She presented to our hospital with a 40cm giant solid mass and severe respiratory failure, and was scheduled for an operation. We determined that we could not obtain a sufficient tidal volume without spontaneous respiration. Therefore, we chose to perform awake intubation and not to use a muscle relaxant before the operation. At the start of the operation, when muscle relaxant was first administered, we could not obtain a sufficient tidal volume. An abdominal midline incision was performed immediately and her tidal volume recovered. Her resected tumor weighed 10.5kg. After removal of her tumor, her tidal volume was maintained at a level consistent with that under spontaneous respiration to avoid occurrence of re-expansion pulmonary edema. Conclusions We performed successful anesthetic management of a case of growing teratoma syndrome with a giant abdominal tumor. Respiratory management was achieved by avoiding use of a muscle relaxant before the operation to maintain spontaneous respiration and by maintaining a relatively low tidal volume, similar to that during spontaneous respiration preoperatively, after removal of the tumor to prevent re-expansion pulmonary edema.

Abstract
[Purpose] During exercise, skeletal muscle motor units are recruited based on afferent
sensory input following peripheral metabolic by-product accumulation. The purpose of this
study was to investigate whether lactate plays a role in conveying fatigue-related
information to the brain. [Subjects] Eleven healthy adults participated in this study.
[Methods] Subjects performed handgrip exercises at 10%, 30%, and 50% maximal voluntary
contraction for 120 s. They were monitored for brachial artery blood pressure, respiratory
quotient, muscle fatigue (integrated electromyogram, median power frequency), blood
lactate levels, muscle blood flow, and brain activity. [Results] The handgrip exercise
protocol caused significant muscle fatigue based on 28% and 37% reductions in median power
frequency detected at 30% and 50% maximal voluntary contraction, respectively. Subjects
exhibited intensity-dependent increases in blood pressure, respiratory quotient, muscle
blood flow, and circulating lactate concentrations. Furthermore, brain activity increased
at 30% and 50% maximal voluntary contraction. Multiple regression analysis identified
muscle blood flow at 30% maximal voluntary contraction and lactate at 50% maximal
voluntary contraction with standardized partial regression coefficients of −0.64 and 0.75,
respectively. [Conclusion] These data suggest that blood lactate concentration and muscle
blood flow, which reflect muscle metabolism, may convey load intensity information to the
brain during muscle fatigue.

Abstract
Nowadays, the technologies for detecting, processing and interpreting bioelectrical signals have improved tremendously. In particular, surface electromyography (sEMG) has gained momentum in a wide range of applications in various fields. However, sEMG sensing has several shortcomings, the most important being: measurements are heavily sensible to individual differences, sensors are difficult to position and very expensive. In this paper, the authors will present an innovative muscle contraction sensing device (MC sensor), aiming to replace sEMG sensing in the field of muscle movement analysis. Compared with sEMG, this sensor is easier to position, setup and use, less dependent from individual differences, and less expensive. Preliminary experiments, described in this paper, confirm that MC sensing is suitable for muscle contraction analysis, and compare the results of sEMG and MC sensor for the measurement of forearm muscle contraction.

Abstract
Different types of sensors are being used to study deglutition and mastication. These often suffer from problems related to portability, cost, reliability, comfort etc. that make it difficult to use for long term studies. An inertial measurement based sensor seems a good fit in this application; however its use has not been explored much for the specific application of deglutition research. In this paper, we present a system comprised of an IMU and EMG sensor that are integrated together as a single system. With a preliminary experiment, we determine that the system can be used for measuring the head-neck posture during swallowing in addition to other parameters during the swallowing phase. The EMG sensor may not always be a reliable source of physiological data especially for small clustered muscles like the ones responsible for swallowing. In this case, we explore the possibility of using gyroscopic data for the recognition of deglutition events.

Abstract
The authors report a rare case of peritoneal adenomatoid mesothelioma in a woman with no history of asbestos exposure. A 61-year-old woman was originally suspected of having a bilateral ovarian tumor based on chest radiography and magnetic resonance imaging (MRI). Upon referral to our hospital, the presence of two solid masses was confirmed by enhanced MRI and 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (18F-FDG-PET/CT). Physical examination was normal, as were serum concentrations of the tumor markers CA 19-9, CA 125, and CEA. Laparoscopic surgery showed a right ovarian tumor and laparoscopic right salpingo-oophorectomy and adhesiotomy were performed. Two months later, the patient underwent laparoscopic segmental resection of the sigmoid colon, with histological analysis identifying an adenomatoid-like tumor. The final diagnosis was peritoneal adenomatoid-like mesothelioma with invasion of the right ovary. This case report demonstrates that imaging techniques must be coupled with laparoscopic surgery for an accurate diagnosis of peritoneal mesothelioma.

Abstract
To investigate the temporal association between frequency of non-nocturnal hypoglycemia and sleep quality among patients with diabetes receiving insulin therapy.We used data from 1 513 patients with diabetes receiving insulin therapy. We estimated the relative risks (RR) of the frequency of non-nocturnal hypoglycemia for poor sleep quality measured by the Pittsburgh Sleep Quality Index.The average age and HbA1c value of the patients were 63.7 years and 7.8%, respectively. Compared with poor sleep quality in patients without any type of non-nocturnal disabling hypoglycemia (NNDH), the multivariable-adjusted RR values for poor sleep quality were 1.30 (95% confidence interval [CI], 1.06-1.61) and 1.37 (95% CI, 0.96-1.95) in patients who experienced 1-4 and ≥5 episodes of NNDH, respectively (p=0.004). Experiencing non-nocturnal severe hypoglycemia (NNSH) once in the past 90 days significantly increased the risk of poor sleep quality by 1.54 episodes (95% CI, 1.16-2.05; p=0.003). By adding the presence of depression as a variable to the multivariable-adjusted model, these associations were attenuated because we did not observe any significant association between NNDH and poor sleep quality (p=0.178). However, a significant association between NNSH and poor sleep quality was observed (RR=1.43; 95% CI, 1.09-1.90; p=0.011).A high frequency of non-nocturnal hypoglycemia was associated with poor sleep quality in patients with diabetes receiving insulin therapy. Our data also suggested that the association of NNDH, and not NNSH, was mediated by comorbid depression.

Abstract
Intrathoracic neurofibromas originating from the vagus nerve in patients without von Recklinghausen disease is rare and poses a problem in etiological diagnosis. Surgical resection is usually necessary for precise diagnosis of such tumors. We report the first case of a neurofibroma originating from the right pulmonary branch of the vagus nerve in a 34-year-old male without von Recklinghausen disease. The diagnosis was suggested by the radiological features and was confirmed histologically after resection.

Abstract
Transfer of type-1 helper T-conditioned (Th1-conditioned) cells promotes functional recovery with enhanced axonal remodeling after spinal cord injury (SCI). This study explored the molecular mechanisms underlying the beneficial effects of pro-inflammatory Th1-conditioned cells after SCI. The effect of Th1-conditioned cells from interferon-γ (ifn-γ) knockout mice (ifn-γ−/− Th1 cells) on the recovery after SCI was reduced. Transfer of Th1-conditioned cells led to the activation of microglia (MG) and macrophages (MΦs), with interleukin 10 (IL-10) upregulation. This upregulation of IL-10 was reduced when ifn-γ−/− Th1 cells were transferred. Intrathecal neutralization of IL-10 in the spinal cord attenuated the effects of Th1-conditioned cells. Further, IL-10 is robustly secreted from Th1-conditioned cells in an ifn-γ-dependent manner. Th1-conditioned cells from interleukin 10 knockout (il-10−/−) mice had no effects on recovery from SCI. These findings demonstrate that ifn-γ-dependent secretion of IL-10 from Th1 cells, as well as native MG/MΦs, is required for the promotion of motor recovery after SCI.
