Abstract
A nationwide retrospective study for the clinical outcomes of 99 patients who had received thymoglobulin at a median total dose of 2.5 mg/kg (range, 0.5-18.5 mg/kg) as a second-line treatment for steroid-resistant acute GvHD was conducted. Of the 92 evaluable patients, improvement (complete or partial response) was observed in 55 patients (60%). Multivariate analysis demonstrated that male sex and grade III and IV acute GvHD were associated with a lower improvement rate, whereas thymoglobulin dose (<2.0, 2.0-3.9 and ⩾4.0 mg/kg) was NS. Factors associated with significantly higher nonrelapse mortality included higher patient age (⩾50 years), grade IV acute GvHD, no improvement of GvHD and higher dose of thymoglobulin (hazard ratio, 2.55; 95% confidence interval, 1.34-4.85; P=0.004 for 2.0-3.9 mg/kg group and 1.79; 0.91-3.55; P=0.093 for ⩾4.0 mg/kg group). Higher dose of thymoglobulin was associated with a higher incidence of bacterial infections, CMV antigenemia and any additional infection. Taken together, low-dose thymoglobulin at a median total dose of 2.5 mg/kg provides a comparable response rate to standard-dose thymoglobulin reported previously, and <2.0 mg/kg thymoglobulin is recommended in terms of the balance between efficacy and adverse effects.

Abstract
Antimicrobial peptides (AMPs), also referred to as host defence peptides (HDPs), comprise a large family of small molecules broadly distributed throughout the animal and plant kingdom, historically serving as natural antibiotics. In mammals, there are two major families of AMPs/HDPs, the defensins and the cathelicidins. These peptides have evolved to protect against a wide range of infections from bacteria, viruses, fungi and some parasites. However, in addition to their broad-spectrum killing activities, AMPs/HDPs also possess various biological functions. They activate a variety of cell types, such as keratinocytes, airway epithelial cells and mast cells, among others, and regulate cytokine/chemokine production, cell migration, proliferation, differentiation, angiogenesis, the wound healing process and maintenance of the skin barrier function. Recently, it has become clear that alterations in the level of AMPs/HDPs are associated with the initiation and development of various inflammatory and allergic diseases. In this review, we will discuss the regulation and functions of human β-defensins and outline the current evidence supporting the role of these peptides in the pathogenesis of allergic diseases, including atopic dermatitis, allergic rhinitis, asthma and chronic rhinosinusitis. Understanding the functions and mechanisms of human β-defensins may aid in the development of novel therapeutic strategies for allergic diseases.

Abstract
A new tracer-encapsulated solid pellet (TESPEL) injection system has been developed additionally for the LHD heliotron. This system has three-dimensionally bended guide tubes, which allows us to inject the TESPEL obliquely on a poloidal cross-section of the LHD plasma. Consequently, this system enables us to control a tracer-impurity-deposited location more precisely. Moreover, this system can make it possible for the tracer impurity to be deposited even only inside the ergodic region (outside a last closed flux surface of the LHD plasma). A stereoscopic fast camera system has been also developed for capturing a three-dimensional TESPEL trajectory.

Abstract
Intention recognition through decoding brain activity could lead to a powerful and independent Brain-Computer-Interface (BCI) allowing for intuitive control of devices like robots. A common strategy for realizing such a system is the motor imagery (MI) BCI using electroencephalography (EEG). Changing to invasive recordings like electrocorticography (ECoG) allows extracting very robust features and easy introduction of an idle state, which might simplify the mental task and allow the subject to focus on the environment. Especially for multi-channel recordings like ECoG, common spatial patterns (CSP) provide a powerful tool for feature optimization and dimensionality reduction. This work focuses on an invasive and independent MI BCI that allows triggering from an idle state, and therefore facilitates tele-operation of a humanoid robot. The task was to lift a can with the robot's hand. One subject participated and reached 95.4 % mean online accuracy after six runs of 40 trials. To our knowledge, this is the first online experiment with a MI BCI using CSPs from ECoG signals.

Abstract
The β2-adrenergic receptor (β2-AR) is highly expressed in various human neoplasms and has been considered a novel therapeutic target of cancer treatment. However, the clinicopathological significance of β2-AR expression in patients with gastric cancer (GC) remains unclear. The aim of this study was to explore β2-AR expression and its prognostic significance. A total of 331 patients with surgically resected GC were evaluated. Tumor sections were stained immunohistochemically for β2-AR. And, we confirmed β2-AR expression in the GC cell lines by Western blot. β2-AR was highly expressed in 30.5 % of GC patients. Expression was significantly associated with age, T factor, tumor differentiation, histology of non-signet cells, lymphatic permeation, and vascular invasion. And, all the GC cell lines expressed β2-AR. On univariate analysis, age, disease stage, T factor, N factor, lymphatic permeation, vascular invasion, and β2-AR expression were significantly associated with overall survival. Although the multivariate analysis did not indicate that β2-AR expression was independently prognostic of survival, high-level β2-AR expression was associated with significantly poorer survival of GC patients with well or moderately differentiated tumors. β2-AR expression was a significant predictor of tumor aggressiveness in, and poorer survival of, patients with GC.

Abstract
AIMS To examine if a simple biomarker can identify people with diabetes who are at high risk of atrial fibrillation. METHODS A retrospective cohort study was conducted at a single centre in people with Type 2 diabetes referred to our department between January 2000 and December 2007. In 517 consecutive people without any history, signs or symptoms of atrial fibrillation at baseline, the association between baseline B-type natriuretic peptide level and future atrial fibrillation incidence was examined, with adjustments for other potentially confounding factors. RESULTS A total of 28 people were diagnosed with new-onset atrial fibrillation during a median 6-year follow-up. When people were categorized into three groups according to B-type natriuretic peptide clinical thresholds (20 and 100 pg/ml), hazard ratios for the development of atrial fibrillation in the middle and highest B-type natriuretic peptide groups were 2.8 and 9.4, respectively, compared with the lowest B-type natriuretic peptide group. Time-dependent receiver-operating curve analysis identified a threshold for B-type natriuretic peptide to detect atrial fibrillation development of 52.8 pg/ml (sensitivity 75.2%, specificity 68.8%). The B-type natriuretic peptide predictive value was independent of and similar to that of left atrial size and ventricular dimension. CONCLUSION In people with Type 2 diabetes, high baseline B-type natriuretic peptide levels were significantly associated with future atrial fibrillation development.

Abstract
To clarify the morphologic features of the ocular disease recently occurring among Japanese Black cattle in southern Kyushu, 6 globes from 3 Japanese Black cattle, between 11 and 20 months old (cow Nos. 1 to 3), were pathologically examined. cow Nos. 1 and 2 were sired by the same Japanese Black bull, and cow No. 3 was sired by the ancestor (sire) of the former bull. The ocular lesions were pathologically similar to each other, except for the left eye of cow No. 1. The ocular lesions of 5 globes were characterized by microphthalmia, hypoplasia, and/or dysplasia of the lenses; persistence of the primary vitreous; and retinal dysplasia with total nonattachment. The left globe from cow No. 1 had no lens and severe hypoplasia and nonattachment of the retina. Because dysplastic retinal lesions that formed crescentic folds and a central column were the most characteristic features of the eyes, the falciform retinal fold with congenital nonattachment was the most likely disease entity. Although the cause of the ocular disease could not be clarified with the present study, an inherited ocular defect of the bull and its ancestor was suspected.

Abstract
BACKGROUND Studies have revealed that patients who undergo preemptive kidney transplantation (PKT) have favorable prognoses compared with those who undergo kidney transplantation after the initiation of dialysis. The number of PKT cases performed worldwide has been increasing. The goal of this study was to determine the clinical characteristics of patients who may successfully receive PKT. METHODS A single-center, case-control study was conducted to determine the clinical factors that lead to referral for PKT. RESULTS Between April 1, 2009, and August 1, 2015, a total of 118 patients underwent living donor kidney transplantation. Thirty of these patients had not undergone dialysis before their initial visit to the study hospital. Of these, 20 received kidney transplantation before and after dialysis initiation, respectively (group PKT+, successful PKT; group PKT-, failed PKT). The baseline characteristics at the primary visit were compared between groups. The median duration from the first visit to the study institution to PKT was 5.6 ± 0.7 months. Serum creatinine (Cr) levels differed significantly between groups (PKT+ vs PKT-, 6.0 ± 0.3 mg/dL vs 7.5 ± 0.5 mg/dL; P = .03). The receiver-operating characteristic curves revealed that a serum Cr level >5.7 mg/dL at the initial visit to the unit was a cutoff point for predicting the success of PKT (area under the curve, 0.721; P = .02). CONCLUSIONS Our results indicate that PKT should be performed within ∼6 months of the initial visit to the transplant center. Serum Cr levels <5.7 mg/dL predict successful PKT.

Abstract
BACKGROUND Accurate evaluation of thrombogenicity helps to prevent thrombosis and excessive bleeding. The total thrombus-formation analysis system (T-TAS) was developed for quantitative analysis of platelet thrombus formation by the use of microchips with thrombogenic surfaces (collagen, platelet chip [PL-chip]; collagen plus tissue factor, atherome chip [AR-chip]). We examined the utility of the T-TAS in the assessment of the efficacy of antiplatelet therapy in patients with coronary artery disease (CAD). METHODS AND RESULTS In this cross-sectional study, 372 consecutive patients admitted to the cardiovascular department were divided into three groups: patients not receiving any antiplatelet therapy (control, n = 56), patients receiving aspirin only (n = 69), and patients receiving aspirin and clopidogrel (n = 149). Blood samples were used for the T-TAS to measure the platelet thrombus-formation area under the curve (AUC) at various shear rates (1500 s(-1) [PL18 -AUC10 ] and 2000 s(-1) [PL24 -AUC10 ] for the PL-chip; 300 s(-1) [AR10 -AUC30 ] for the AR-chip). The on-clopidogrel platelet aggregation was measured by the use of P2Y12 reaction units (PRUs) with the VerifyNow system. The mean PL24 -AUC10 levels were 358 ± 111 (± standard deviation) (95% confidence interval [CI] 328.9-387.1) in the control group, 256 ± 108 (95% CI 230.5-281.5) in the aspirin group, and 113 ± 91 (95% CI 98.4-127.6) in the aspirin/clopidogrel group. In the aspirin/clopidogrel group, the PL24 -AUC10 was higher in poor metabolizers (PMs) with cytochrome P450 2C19(CYP2C19) polymorphisms (152 ± 112, 95% CI 103.4-200.6) than in the non-PM group (87 ± 74, 95% CI 73.8-100.2). CONCLUSIONS Our findings suggest that the PL24 -AUC10 level measured by the T-TAS is a potentially suitable index for the assessment of antiplatelet therapy in CAD patients.

Abstract
This study demonstrates the feasibility of high-gamma activity mapping for localization of somatosensory finger areas in the human brain. Identification of functional brain regions is important in surgical planning, such as for resections of epileptic foci or brain tumors. The mapping procedure is done using electrocorticography (ECoG), an invasive technique in which electrical brain signals are acquired from the cortical surface. Two epilepsy patients with implanted electrode grids participated in the study. Data were collected during a vibrotactile finger stimulation paradigm and showed significant cortical activation (p <; 0.001) in the high-gamma range over the contralateral somatosensory cortex. The results are consistent with previous studies that used fMRI in test subjects without implanted electrodes. Therefore, the results suggest that localizing the cortical representations of the fingers in clinical practice using ECoG is feasible, even without the patient's active participation.

Abstract
OBJECTIVE To determine the clinical effectiveness of a community milk fluoridation programme. BASIC RESEARCH DESIGN Parallel arm 5-year cohort study, with final cross-sectional comparisons between groups. PARTICIPANTS 3-year-olds in 8 Bulgarian cities/towns entered the cohort study with random samples (n = 1,782) recruited at baseline in 2004. After 5 years in 2009 sub-samples (about 30%) of these now aged 8 were randomly selected in intervention sites for follow-up examination (n = 454); 276 controls were examined at the age 8 years. For cross-sectional comparisons, in 2004, 284 3-year-olds from control cities were baseline examined for caries, then 276 children at the age 8 years in 2009. INTERVENTIONS In six intervention communities: 1,498 examined children received 0.5 mg F in 100 or 200 ml school milk or yogurt provided each school day; a further 180 received non-fluoridated milk. In two control communities, fluoride was not added to 284 children's school milk. MAIN OUTCOME MEASURES Dental caries experience of primary, and permanent teeth. RESULTS For primary teeth, caries increments were 46% (p < 0.001) and 30% (p < 0.01) lower in the fluoridated milk groups compared with non-fluoridated milk groups in the intervention and control communities, respectively. For permanent teeth those reductions were 61% and 53% (p < 0.001). The cross-sectional comparisons of 8-year-olds showed significant changes in dental caries experience over time; in children consuming fluoridated milk the level of dmfs fell by 43% (2004 and 2009) against 11% in the control group. Among children consuming fluoridated milk the DMFS fell 68% against rising 3% in the controls. CONCLUSIONS Fluoridated milk delivered daily in schools in Bulgaria resulted in substantially lower caries development compared with children in schools receiving milk without added fluoride. The nation-wide experiences from milk fluoridation indicate that such a public health scheme can be effective to the global fight against dental caries of children.

Abstract
Decoding brain activity of corresponding highlevel tasks may lead to an independent and intuitively controlled Brain-Computer Interface (BCI). Most of today's BCI research focuses on analyzing the electroencephalogram (EEG) which provides only limited spatial and temporal resolution. Derived electrocorticographic (ECoG) signals allow the investigation of spatially highly focused task-related activation within the high-gamma frequency band, making the discrimination of individual finger movements or complex grasping tasks possible. Common spatial patterns (CSP) are commonly used for BCI systems and provide a powerful tool for feature optimization and dimensionality reduction. This work focused on the discrimination of (i) three complex hand movements, as well as (ii) hand movement and idle state. Two subjects S1 and S2 performed single `open', `peace' and `fist' hand poses in multiple trials. Signals in the high-gamma frequency range between 100 and 500 Hz were spatially filtered based on a CSP algorithm for (i) and (ii). Additionally, a manual feature selection approach was tested for (i). A multi-class linear discriminant analysis (LDA) showed for (i) an error rate of 13.89 % / 7.22 % and 18.42 % / 1.17 % for S1 and S2 using manually / CSP selected features, where for (ii) a two class LDA lead to a classification error of 13.39 % and 2.33 % for S1 and S2, respectively.

Abstract
For neurosurgery with an awake craniotomy, the critical issue is to set aside enough time to identify eloquent cortices by electrocortical stimulation (ECS). High gamma activity (HGA) ranging between 80 and 120 Hz on electrocorticogram (ECoG) is assumed to reflect localized cortical processing. In this report, we used realtime HGA mapping and functional magnetic resonance imaging (fMRI) for rapid and reliable identification of motor and language functions. Three patients with intra-axial tumors in their dominant hemisphere underwent preoperative fMRI and lesion resection with an awake craniotomy. All patients showed significant fMRI activation evoked by motor and language tasks. After the craniotomy, we recorded ECoG activity by placing subdural grids directly on the exposed brain surface. Each patient performed motor and language tasks and demonstrated realtime HGA dynamics in hand motor areas and parts of the inferior frontal gyrus. Sensitivity and specificity of HGA mapping were 100% compared to ECS mapping in the frontal lobe, which suggested HGA mapping precisely indicated eloquent cortices. The investigation times of HGA mapping was significantly shorter than that of ECS mapping. Specificities of the motor and language-fMRI, however, did not reach 85%. The results of HGA mapping was mostly consistent with those of ECS mapping, although fMRI tended to overestimate functional areas. This novel technique enables rapid and accurate functional mapping.

Abstract
OBJECTIVE To investigate the relationship of dental status to food diversity among older Japanese. DESIGN AND SETTING A community-based cross-sectional study conducted in the town of Tosa, Kochi Prefecture, Japan. METHODS The study participants were 252 Japanese (84 men and 168 women, average age 81.2 years) and dentate participants were classified into three groups: 1-9 teeth, 10-19 teeth and 20 or more teeth. Food diversity was assessed as a validated measure of dietary quality using the 11-item Food Diversity Score Kyoto (FDSK-11), which evaluates frequency of consumption of 11 main food groups. Multivariable analysis of the differences in FDSK-11 score ranging from 0 to 11, with a higher score indicating greater food diversity, among the three dental status groups was conducted using general linear models. All the performed analyses were stratified by gender. RESULTS There was no association between dental status and food diversity score in models for men. In contrast, women with ≤ 9 teeth and with 10-19 teeth had significantly lower FDSK-11 scores than women with ≥ 20 teeth after adjusting for confounders (p < 0.001 and p = 0.009, respectively). Additionally, there was a trend toward lower scores for FDSK-11 with fewer teeth (p = 0.001). CONCLUSION A less varied diet, as indicated by low FDSK-11 score, was observed in female participants with fewer teeth. Tooth loss was associated with poor diet quality among older Japanese women.

Abstract
We treated a 64-year-old woman with high blood pressure. Catecholamine metabolite levels were elevated in the blood and urine. CT revealed a densely stained tumor on the right side of the descending aorta dorsal to the inferior vena cava. PET-CT revealed abnormal accumulation of (18) F-fluorodeoxyglucose, and (123) I-meta-iodo-benzylguanidine uptake was apparent on scintigraphy. The tumor was determined to be a paraganglioma located on the border between the thoracic and abdominal cavities, and laparoscopic tumorectomy was performed. The patient was placed in the left lateral position. The right lobe of the liver was turned over, and we cut the diaphragm to expose the front of the tumor. We resected the straight artery flowing in from the aorta and removed the tumor safely. Herein, we describe the removal of a paravertebral paraganglioma located in the border of the thoracic and abdominal cavities with a laparoscopic transabdominal-transdiaphragmatic approach.

Abstract
The dorsal resting hair of C3H mice at various ages was shaved, thus activating the hair into the anagen stage. New hair growth after shaving was not uniform in the various age groups. Furthermore, an increasing delay in hair regrowth was observed as the mice became older (20, 66, 188, and 312 days). In the biochemical analysis of hair regrowing and nongrowing skins after shaving, activities of ornithine decarboxylase, transglutaminase, and alkaline phosphatase had higher values in the extract of the hair regrowing area compared with that in the nongrowing area. In studying the effects of various physical and chemical treatments on hair growth after shaving, repeated shaving was in itself clearly shown to stimulate hair growth. Amongst all of the treatments that were applied, topical application of TPA was most able to accelerate hair regrowth, followed by UV irradiation and retinoic acid treatment. Suppression of hair regrowth was observed in PUVA, DHT, and estradiol; and complete inhibition was seen in the animals treated with betamethasone valerate. In biochemical studies, a relatively good correlation was observed between the rate of hair regrowth and skin ODC activities after treatment.

Abstract
The membranous fraction isolated from stratum corneum by 8M urea-beta ME containing alkaline buffer (pH 9.0) is quite crude when observed by electron microscopy. However, this procedure may be useful for clinical samples, as one can isolate and compare both the soluble (interfilamentous) fraction and the keratin filament from the same sample in addition to the residues (membranous fraction). A further purified membranous fraction was isolated by a new method. Human stratum corneum was chopped and treated with 8M urea-50 mM Tris-HCl (pH 9.0), digested by the use of trypsin, and the product fractionated by a sucrose density gradient to obtain separate single cells without the cytoplasm. One sample was then treated with trypsin for 1 hour and another with urea buffer for 24 hours. Observations revealed a thickened inner membrane (marginal band) of approximately 150A. Each of the membranous samples contained a level of half-cystine markedly higher in amount (around 100/1,000) and involved mostly in the epsilon-(gamma-glutamyl) lysine cross-linkages (around 30%). In order to compare the membranous fraction of horny and living cells (marginal bands and plasma membranes), the fraction was then isolated from living cells. The relative amino acid composition of the membranous fraction of the plasma membrane resembled that of human erythrocytes, but was quite different from that of the marginal band. These comparative studies of biochemical and morphological features suggested the importance of S-S cross-linking enzymes and transglutaminase in the transformation mechanism of the marginal band.

Abstract
Fibrous proteins of human stratum corneum were isolated with urea-Tris buffer (pH 9.0) with and without 2-mercaptoethanol (2ME). Comparative studies were made of the biochemical and morphological properties of purified samples obtained with and without 2ME. The final yield of fibrous protein extracted with 2ME was 17 times higher than the yield extracted without 2ME. Identical results were found for the 2 samples by electron microscopic observation, SDS gel electrophoresis with urea and 2ME, and amino acid analysis. However, high molecular weight staining patterns appeared on the SDS gel when the fibrous protein extracted without 2ME was treated with sample buffer containing 4 M urea but no 2ME. These staining patterns were indicative of cross-linking with disulphide bonds. Extraction of the structural proteins with or without 2ME produced the same amount of polymerized fibrous protein. These results suggested that the structural polypeptides of fibrous protein were constructed through ionic forces rather than disulphide bonds. Electron microscopic observation also did not show any differences in the fibrous structures constructed with or without 2ME. The structural polypeptide molecules, than, may be stabilized by partial cross-linking with disulphide bonds. It is possible that the addition of 2ME cleaves disulphide bonds in cell membrane structures and releases fibrous components more effectively than the addition of agents which physically disrupt membrane structures. Consequently, the increase of yield of fibrous protein by the addition of 2ME might be mainly due to cleaving of the membrane structures and partially due to cleaving interpolypeptide disulphide bonds.

Abstract
Activating mutations in the Kirsten rat sarcoma viral oncogene homolog (KRAS) loci are largely predictive of resistance to epidermal growth factor receptor (EGFR) therapy in colorectal cancer (CRC). A highly sensitive detection system for the KRAS gene mutations is urgently needed; however, conventional methods have issues with feasibility and cost performance. Here, we describe a novel detection system using a fluorescence ‘Eprobe’ capable of detecting low level KRAS gene mutations, via real-time PCR, with high sensitivity and simple usability. We designed our Eprobes to be complementary to wild-type (WT) KRAS or to the commonly mutated codons 12 and 13. The WT Eprobe binds strongly to the WT DNA template and suppresses amplification by blocking annealing of the primer during PCR. Eprobe-PCR with WT Eprobe shows high sensitivity (0.05–0.1% of plasmid DNA, 1% of genomic DNA) for the KRAS mutation by enrichment of the mutant type (MT) amplicon. Assay performance was compared to Sanger sequencing using 92 CRC samples. Discrepancies were analyzed by mutation genotyping via Eprobe-PCR with full match Eprobes for 7 prevalent mutations and the next generation sequencing (NGS). Significantly, the Eprobe system had a higher sensitivity for detecting KRAS mutations in CRC patient samples; these mutations could not be identified by Sanger sequencing. Thus, the Eprobe approach provides for highly sensitive and convenient mutation detection and should be useful for diagnostic applications.

Abstract
It remains poorly understood how symptoms in allergic rhinitis are most severe during overnight or early in the morning. The circadian clock consisting of a network of several ‘clock genes’ including Clock drives daily rhythms in physiology. This study showed that allergen-induced surface CD203c expression on basophils in seasonal allergic rhinitis caused by Japanese cedar pollen exhibited a time-of-day-dependent variation associated with temporal variations in canonical circadian clock gene expression. We also found that bone-marrow-derived basophils (BM basophils) generated from wild-type mice exhibited a time-of-day-dependent variation in IgE-mediated IL-4 and histamine production, which was not observed in BM basophils generated from Clock-mutated mice. Therefore, allergen-specific basophil reactivity shows daily variations depending on the circadian clock activity in basophils, which could partly explain temporal symptomatic variations in allergic rhinitis. Additionally, circadian variations in CD203c expression should be considered for interpretation of this biomarker in clinical research.

Abstract
A 62-year-old woman visited a nearby hospital with chief complaints of diarrhea and weight loss.A computed tomography (CT)scan showed a hypovascular tumor approximately 2 cm in diameter in the pancreatic uncus, and the patient was referred to our department for thorough examination and treatment.The patient was diagnosed with cT4 (A) N0M0, cStage IV a cancer of the pancreatic uncus.The treatment consisted of 3 weeks of gemcitabine and 1 week of drug withdrawal; after completion of 4 courses, concomitant administration of S-1 (ie GS therapy) was initiated.The tumor gradually shrank, and it was not observed on a CT scan 1 year and 8 months later.Although no obvious distant metastasis was observed, a low density area around the superior mesenteric artery still remained.Possibility of viable tumor could not be completely ruled out; therefore, a pancreaticoduodenectomy was scheduled.However, because sclerosis around the superior mesenteric artery was quite severe, bled easily, and was difficult to separate, we decided that excision was impossible and resumed the GS therapy. The primary lung cancer that developed subsequently was resected, and the GS therapy was continued.The tumor in the pancreatic uncus was resected after growth was observed 3 years and 9 months after the initiation of chemotherapy.The patient is currently receiving chemotherapy as an outpatient.

Abstract
The patient was a 40-year-old woman.She began experiencing abdominal pain and constipation in July 2005.S he underwent endoscopy in August, which revealed rectal cancer.She was referred to our hospital for surgery and underwent anterior resection with lymph node dissection in September. The pathological diagnosis was tub2, SS, N2, ly1, v1, stage III b. After discharge, she began oral chemotherapy. However, in April 2006, computed tomography (CT) revealed recurrence in the Douglas pouch. She began FOLFOX4 treatment in May.On follow-up CT performed in July, the recurrent sites were limited to 2 nodules and were deemed resectable. The patient underwent peritoneal dissemination resection, and the pathological diagnosis was metastatic tumor.She subsequently received 11 postoperative FOLFOX4 courses. The chemotherapy regimen was changed to the de Gramont regimen because of peripheral neuropathy. After 56 courses of the de Gramont regimen, the chemotherapy regimen was further changed to UFT/UZEL. The patient received 28 additional courses but experienced hair loss and requested treatment cessation. To date, she remains alive without recurrence.

Abstract
A pulsed slow-positron beam generated by an electron linear accelerator was directly used for positron annihilation lifetime spectroscopy without any positron storage devices. A waveform digitizer was introduced to simultaneously capture multiple gamma-ray signals originating from positron annihilation events during a single accelerator pulse. The positron pulse was chopped and bunched with the chopper signals also sent to the waveform digitizer. Time differences between the annihilation gamma-ray and chopper peaks were calculated and accumulated as lifetime spectra in a computer. The developed technique indicated that positron annihilation lifetime spectroscopy can be performed in a 20 μs time window at a pulse repetition rate synchronous with the linear accelerator. Lifetime spectra of a Kapton sheet and a thermally grown SiO2 layer on Si were successfully measured. Synchronization of positron lifetime measurements with pulsed ion irradiation was demonstrated by this technique.

Abstract
BACKGROUND Few studies have evaluated the effects of rabeprazole on low-dose aspirin (LDA)-induced gastroduodenal injuries. AIM To conduct a randomised, double-blind, triple-dummy, active-controlled, multicentre trial, named the PLANETARIUM study, to assess the efficacy, dose-response relationship and safety of rabeprazole for peptic ulcer recurrence in Japanese patients on long-term LDA therapy. METHODS Eligible patients had a history of endoscopically confirmed peptic ulcers and were receiving long-term LDA (81 or 100 mg/day) therapy for cardiovascular or cerebrovascular protection. Subjects were randomly segregated into three groups receiving rabeprazole 10 mg once daily (standard dose in Japan), rabeprazole 5 mg once daily, or teprenone (geranylgeranylacetone; mucosal protective agent commercially available in Japan) 50 mg three times per day as an active control. The primary endpoint was recurrence of peptic ulcers over 24 weeks. RESULTS Among 472 randomised subjects, 452 subjects (n = 151, 150, 151, respectively) constituted the full analysis set. The cumulative recurrence rates of peptic ulcers over 24 weeks in the 10- and 5-mg rabeprazole groups were 1.4% and 2.8%, respectively, both of which were significantly lower than that in the teprenone group (21.7%). The cumulative occurrence rate of bleeding ulcers over 24 weeks in the teprenone group was 4.6%, while bleeding ulcers were not observed in the 10- or 5-mg rabeprazole groups. Rabeprazole was well tolerated at both doses. CONCLUSION Rabeprazole prevents the recurrence of peptic ulcers with no evidence of a major dose-response effect in subjects on low-dose aspirin therapy.

Abstract
BACKGROUND S100A7/psoriasin is a member of the S100 protein family and is encoded in the epidermal differentiation complex, which contains genes for markers of epidermal differentiation. S100A7/psoriasin is overexpressed in hyperproliferative skin diseases, where it is believed not only to exhibit antimicrobial functions, but also to induce immunomodulatory activities, including chemotaxis and cytokine/chemokine production. OBJECTIVES To evaluate the effect of S100A7/psoriasin on keratinocyte differentiation and regulation of the tight junction (TJ) barrier. METHODS Expression of differentiation markers and TJ proteins in human keratinocytes was determined by real-time polymerase chain reaction and Western blot. The changes in TJ barrier function were assessed by transepithelial electrical resistance and paracellular permeability assays. Glycogen synthase kinase-3 (GSK-3) and mitogen-activated protein kinase (MAPK) activation was analysed by Western blot, whereas β-catenin and E-cadherin activation was evaluated by Western blot and immunofluorescence. RESULTS S100A7/psoriasin enhanced the expression of several differentiation markers and selectively increased the expression of TJ proteins (e.g. claudins and occludin), which are known to strengthen the TJ barrier. Furthermore, S100A7/psoriasin increased β-catenin and E-cadherin accumulation at cell-cell contact, and enhanced transepithelial electrical resistance while reducing the paracellular permeability of keratinocyte layers. The data suggest that S100A7/psoriasin-mediated regulation of the TJ barrier was via both the GSK-3 and MAPK pathways, as evidenced by the inhibitory effects of inhibitors for GSK-3 and MAPKs. CONCLUSIONS Our finding that S100A7/psoriasin regulates differentiation and strengthens TJ barrier function provides novel evidence that, in addition to antimicrobial and immunoregulatory activities, S100A7/psoriasin is involved in skin innate immunity.

Abstract
Bosonic superweakly interacting massive particles (super-WIMPs) are a candidate for warm dark matter. With the absorption of such a boson by a xenon atom, these dark matter candidates would deposit an energy equivalent to their rest mass in the detector. This is the first direct detection experiment exploring the vector super-WIMPs in the mass range between 40 and 120 keV. With the use of 165.9 day of data, no significant excess above background was observed in the fiducial mass of 41 kg. The present limit for the vector super-WIMPs excludes the possibility that such particles constitute all of dark matter. The absence of a signal also provides the most stringent direct constraint on the coupling constant of pseudoscalar super-WIMPs to electrons. The unprecedented sensitivity was achieved exploiting the low background at a level 10(-4) kg-1 keVee-1 day-1 in the detector.

Abstract
A transglycosylation reaction with moranoline (1-deoxynojirimycin) was done with soluble starch as the glucosyl donor and Bacillus macerans amylase as a cyclodextrin glycosyltransferase [EC 2.4.1.19]. The resultant transglycosylation products with moranoline, obtained by treating the reaction mixture with a strong cation exchange resin, were hydrolyzed by beta-amylase [EC 3.2.1.2] from sweet potatoes. The hydrolysate was treated with a strong cation exchange resin, and high purity maltose was obtained.

Abstract
In recent years, there has been significant progress in systemic chemotherapy for metastatic or recurrent colorectal cancer. We investigated the clinical efficacy and feasibility of the bevacizumab and capecitabine /oxaliplatin(CapeOX)combination for untreated colorectal cancer. From October 2009 to June 2012, 38 patients were included, 18 receiving CapeOX alone and 20 receiving CapeOX plus bevacizumab. The response rate and disease-control rate were 16% and 5 0%, respectively, in the CapeOX arm, and 5 5% and 8 5%, respectively, in the CapeOX plus bevacizumab arm. Median progression-free survival was 8.0 months in the CapeOX arm and 1 2.8 months in CapeOX plus bevacizumab arm. The median overall survival was 21.6 months in the CapeOX arm and 3 4.0 months in CapeOX plus bevacizumab arm. Our results suggest that CapeOX treatment can be useful in the outpatient setting and more effective when combined with bevacizumab. Except in cases of bevacizumab intolerance, addition of bevacizumab to CapeOX treatment is considered useful as first-line therapy for metastatic or recur- rent colorectal cancer.
