Abstract
An arsenic (ars) four-gene operon, containing genes encoding a putative membrane permease (ArsP), a transcriptional repressor (ArsR), an arsenate reductase (ArsC) and an arsenical-resistance membrane transporter (Acr3) was first identified in urease-positive thermophilic Campylobacter (UPTC) isolate, CF89-12. UPTC CF89-12 and some other Campylobacter lari isolates contained their ars four-genes, similarly, differing from that in the reference C. lari RM2100 strain. Two putative promoters and a putative terminator were identified for the operon in UPTC CF89-12. In vivo transcription of the operon was confirmed in the UPTC cells. PCR experiments using two primer pairs designed in silico to amplify two arsR and arsC-acr3 segments, respectively, generated two amplicons, approximately 200 and 350 base pairs, with all 31 of 31 and 19 of 31 C. lari isolates (n = 17 for UPTC; n = 14 for UN C. lari), respectively. An inverted repeat forming a dyad structure, a potential binding site for a transcriptional repressor, was identified in the promoter region. Within the deduced 61 amino acids sequence of the putative arsR open reading frame from the UPTC CF89-12, a metal binding box and a DNA-binding helix-turn-helix motif were identified. The UPTC CF89-12 and some other UPTC isolates isolated from natural environment were resistant to arsenate.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic submucosal dissection (ESD) is increasingly being used to resect early colorectal carcinoma, despite the technical difficulties associated with the procedure. Laparoscopic-assisted colorectal surgery (LAC) is an alternative to open surgery for colorectal cancers, and ESD was recently introduced as another alternative. In this study, we compared ESD with LAC as minimally invasive treatments for early colorectal cancer. PATIENTS AND METHODS The study included 589 patients (297 patients with colorectal intramucosal or slightly submucosal invasive cancers undergoing ESD; 292 patients with T1 colorectal cancers undergoing LAC) who were treated at National Cancer Center Hospital in Tokyo, Japan, between January 1998 and September 2008. The clinical outcomes of ESD and LAC were evaluated retrospectively and compared on the basis of data that were originally collected prospectively. RESULTS In the ESD group, mean tumor size was 37 mm, mean procedure time was 106 minutes, and the en bloc and curative resection rates were 87 % and 80 %, respectively. There were 14 perforations (4.7%) and 5 cases of postprocedure bleeding (1.7%); all complications were successfully managed endoscopically except for one of the perforations, which required emergency surgery. In the LAC group, mean tumor size was 20 mm, mean operation time was 206 minutes, and complications included 31 wound infections, 2 pelvic abscesses, 3 anastomotic leakages, and 1 anastomotic bleed. Stomas were necessary in 93 % of the patients who underwent LAC for rectal cancers located below the peritoneal reflection. CONCLUSIONS ESD was associated with a lower complication rate than LAC, with favorable en bloc and curative resection rates. The safety profile and possibility of curative treatment with colorectal ESD provide advantages for the treatment of early colorectal cancers with nul risk of lymph node metastasis.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has a high diagnostic value in sarcoidosis if the obtained histological specimen is indicative of a non-caseating epithelioid-cell granuloma. However, EBUS-TBNA in sacoidosis sometimes affords solely cytological specimens. OBJECTIVE To investigate the relevance of EBUS-TBNA cytology specimens in diagnosing sarcoidosis. DESIGN The study population comprised 72 patients with sarcoidosis and 116 patients who had thoracic malignancies and intrathoracic lymphadenopathy but were eventually proven to be metastasis-free (controls). The EBUS-TBNA samples obtained for these subjects were blindly evaluated for the presence of epithelioid cell clusters by 2 independent cytoscreeners and a pathologist. RESULTS Interobserver variability in the specimen grading was minimal. The sensitivity and specificity were 65.3% and 94.0%, respectively. The sensitivity was high, at 87.5%, for the combined cytological and histological examinations. Of 7 controls whose cytological specimens showed epithelioid cell clusters, 3 were also deemed positive for sarcoidosis on histological examination, which indicated that they had sarcoid reaction to cancer. CONCLUSIONS Cytological evaluation of the EBUS-TBNA specimens had higher sensitivity than histological evaluation alone for intrathoracic lymphadenopathy due to sarcoidosis. It should be recognized, however, that up to 6% of patients with thoracic malignancy may have sarcoid reaction in non-metastatic lymph nodes.

Abstract
The aim of this study is to examine the relationship between the expression level of excision repair cross-complementation group 1 (ERCC1) and of 2-[18F]-fluoro-2-deoxy-D-glucose (18F-FDG) positron emission tomography (PET) in various thoracic neoplasm.Three hundreds-eight patients [non-small cell lung cancer (NSCLC)(n=56), malignant pleural mesothelioma (MPM)(n=21), pulmonary metastatic tumors (PMT)(n=148), thymic epithelial tumors (n=49) and pulmonary neuroendocrine tumor (n=34)] who underwent 18F-FDG PET before treatment were included in this study. Tumors sections were stained by immunohistochemistry for ERCC1, glucose transporter 1(Glut1), vascular endothelial growth factor (VEGF) and microvessel density (MVD) by determinate by CD34. The expression of ERCC1 in thoracic neoplasms had a positivity of 49% (152/308), and the positive rates of ERCC1 expression in NSCLC, PMT, thymic epithelial tumor, pulmonary neuroendocrine tumor and MPM were 52, 43, 53, 47 and 85%, respectively. The positivity of ERCC1 expression was significantly higher in MPM and SQC than in the other histological types. A statistically significant correlation between ERCC1 expression and 18F-FDG uptake was observed in thymic epithelial tumors, especially thymoma. Moreover, ERCC1 expression was also closely associated with the expression of Glut1, VEGF and MVD.Our results indicated that 18F-FDG uptake may be an alternative biomarker for predicting ERCC1 expression in patients with thymoma.

Abstract
The present study examines the expression of cytolethal distending toxin (cdt) gene encoding a cytotoxin in Campylobacter lari (n=6 urease-negative [UN] C. lari; n=4 urease-positive thermophilic Campylobacter [UPTC]). When reverse transcription polymerase chain reaction (RT-PCR) was carried out with 10 C. lari isolates using a primer pair to amplify the cdtB gene transcript segment, an approximate 260 bp RT-PCR amplicon was generated with all the isolates. In addition, cdtA, cdtB and cdtC gene operon was identified to be polycistronicly transcribed in the C. lari cells. The cdtB gene translation in the C. lari cells was also confirmed by Western blot analysis. Thus, the cdt gene operon in C. lari organisms, including UN C. lari and UPTC, was expressed at the transcriptional and translational levels in the cells. The present results suggest that all three cdt genes may be functional in the cells.

Abstract
We examined the effects of blood flow-restricted, low-intensity resistance exercise (termed kaatsu) using an elastic band for resistance on muscle activation. Nine men performed triceps extension and biceps flexion exercises (four sets respectively) using an elastic band for resistance with blood flow restriction (BFR) or CON (unrestricted blood flow). During a BFR session, subjects wore pressure cuffs inflated to 170-260 mmHg on the proximal region of both arms. Surface electromyography (EMG) was recorded from the triceps brachii and biceps brachii muscles, and mean integrated EMG (iEMG) was analyzed. Blood lactate concentration was obtained before (Pre) and immediately after two exercises (Post). During triceps extension and biceps flexion exercises, muscle activation increased progressively (P < 0.05) under BFR (46% and 69%, respectively) but not under CON (12% and 23%, respectively). Blood lactate concentration at Post was higher (P < 0.05) under BFR than under CON (3.6 and 2.1 mmol/L, respectively). Blood lactate concentration at Post was significantly correlated with increased iEMG in both triceps extension (r = 0.65, P < 0.01) and biceps flexion exercises (r = 0.52, P < 0.05). We conclude that kaatsu training using elastic bands for resistance enhances muscle activation and may be an effective method to promote muscle hypertrophy in older adults or patients with a low level of activity.

Abstract
Ethyl tertiary-butyl ether (ETBE) is a motor fuel oxygenate used in reformulated gasoline. The current use of ETBE in gasoline or petrol is modest but increasing. To investigate the effects of ETBE on splenocytes, mice were exposed to 0 (control), 500 ppm, 1750 ppm, or 5000 ppm of ETBE by inhalation for 6 h/day for 5 days/wk over a 6- or 13-week period. Splenocytes were harvested from the control and exposed mice, and the following cell phenotypes were quantified by flow cytometry: (1) B cells (PerCP-Cy5.5-CD45R/B220), (2) T cells (PerCP-Cy5-CD3e), (3) T cell subsets (FITC-CD4 and PE-CD8a), (4) natural killer (NK) cells (PE-NK1.1), and (5) macrophages (FITC-CD11b). Body weight and the weight of the spleen were also examined. ETBE-exposure did not affect the weight of the spleen or body weight, while it transiently increased the number of RBC and the Hb concentration. The numbers of splenic CD3+, CD4+, and CD8+ T cells, the percentage of CD4+ T cells and the CD4+/CD8+ T cell ratio in the ETBE-exposed groups were significantly decreased in a dose-dependent manner. However, ETBE exposure did not affect the numbers of splenic NK cells, B cells, or macrophages or the total number of splenocytes. The above findings indicate that ETBE selectively affects the number of splenic T cells in mice.

Abstract
We aimed to clarify if Campylobacter lari exerts a cytolethal distending toxin (CDT) effect on HeLa cells. Campylobacter cell lysates (CCLys) from C. jejuni 81-176 and urease-positive thermophilic Campylobacter (UPTC) CF89-12 and UPTC NCTC12893 isolates were shown to exert a CDT effect on HeLa cells with morphological changes examined by Giemsa staining and microscopy. However, Campylobacter lari JCM2530(T) isolate showed no effect. In addition, Campylobacter cell culture supernatant wash gave low or absent toxic effects with both C. jejuni and C. lari organisms. When western blot analysis was carried out to clarify if there was a CDTB effect in the CCLys and soluble fractions from Campylobacter isolates, which had a CDT effect on HeLa cells or did not have any effect, anti-recombinant CjCDTB antibodies identified an immunoreactively positive signal at around approximately 25 kDa on all the C. lari isolates examined, as well as the C. jejuni 81116 strain. Thus, all the Campylobacter isolates including those without any CDT effect were shown to express CDTB at the translational level.

Abstract
The primer pair (C412F/C1228R) constructed previously for the polymerase chain reaction (PCR) identification of the genus Campylobacter using an approximate 800 base pair (bp) 16S rRNA gene target segment proved to be useful for the identification of a total of 49 Campylobacter lari isolates including urease-positive thermophilic Campylobacter (UPTC) organisms (n=25). When the primer pair (CLF/R) developed previously for the PCR identification of C. lari species using an approximate 250 bp glyA segment was employed, 27 C. lari isolates, including all the UPTC isolates, were identified to be PCR-negative (55%). Therefore, this PCR procedure developed for the molecular identification of C. lari was shown to be unreliable for C. lari identification. Nucleotide sequencing analysis clarified the reason(s) why PCR-negative examples occurred in many C. lari isolates, including UPTC isolates. The primer pair target sequences in the C. lari-specific PCR-negative isolates apparently varied at the 3' end region, as compared with C. lari-specific PCR-positive isolates. Thus, the multiplex PCR assay developed previously was shown to be unreliable for the molecular identification of C. lari subspecies organisms.

Abstract
We have developed a novel tuberculosis (TB) vaccine; a combination of the DNA vaccines expressing mycobacterial heat shock protein 65 (HSP65) and interleukin 12 (IL-12) delivered by the hemagglutinating virus of Japan (HVJ)-envelope and -liposome (HSP65 + IL-12/HVJ). This vaccine provided remarkable protective efficacy in mouse model compared to the BCG. This vaccine also provided therapeutic efficacy against multi-drug resistant TB (MDR-TB) and extremely drug resistant TB (XDR-TB) in murine models. Furthermore, we extended our studies to a cynomolgus monkey model, which is currently the best animal model of human tuberculosis. This novel vaccine provided a higher level of the protective efficacy than BCG based upon the assessment of mortality. The BCG prime and HSP65 + IL-12/HVJ vaccine (boost) by the prime-boost method showed a synergistic prophylactic effect in the monkey. Furthermore, this vaccine exerted therapeutic efficacy (100% survival) and augmentation of immune responses in the TB-infected monkeys.HVJ-Envelope/HSP65 DNA + IL-12 DNA vaccine increased the body weight of TB-infected monkeys, improved the ESR, and augmented the immuneresponses (proliferation of PBL and IL-2 production). The enhancement of IL-2 production from monkeys treated with this vaccine was correlated with the therapeutic efficacy of the vaccine. These data indicate that our novel DNA vaccine might be useful against Mycobacterium tuberculosis including XDR-TB and MDR-TB for human therapeutic clinical trials.

Abstract
Spirometry is practically the only tool to evaluate pulmonary functions. Other automatic systems comparable to spirometry are expected. A fiber-grating (FG) vision sensor is a non-contact respiratory monitoring system to detect changes in volumes by measuring the movement of laser spots on the body surface. We examined the contributions of the FG sensor to evaluating pulmonary functions. The FG sensor showed a linear correlation with spirometry in tidal volumes (TV) obtained from five controls (R = 0.98, P < 0.0001). We also showed agreement of TV between the two devices using Bland-Altman analysis. TV measured by the FG sensor were reproducible and applicable to distinct subjects. To detect airway obstruction, we performed forced expiration in controls (n = 16) and chronic obstructive pulmonary disease (COPD) patients (n = 18) with the FG sensor and spirometry. Forced expiratory volume in 1 s (FEV(1)) and FEV(1)/forced vital capacity in COPD patients were lower than those in controls by the FG sensor. In addition, prolonged expiration in natural breathing by the FG sensor was related to airflow limitation by spirometry. The FG sensor was helpful to measure volume changes and to evaluate pulmonary functions in controls and patients with COPD. Its upcoming clinical applications are promising for simplicity and feasibility.

Abstract
It has been reported previously that artificial gastric ulcers caused by endoscopic submucosal dissection (ESD) would heal within 8 weeks, irrespective of their size and location. The aim of this retrospective study was to describe long-term outcomes of gastric ESD ulcers. Check-up of ulcers was performed by periodic endoscopy. The rate of ESD ulcer recurrence and clinicopathological factors that may relate to recurrence were assessed. During the median observation period of 33 months, a benign ulcer recurrence occurred in 10 lesions in 10 patients (2.1%). Univariate analysis showed that Helicobacter pylori infection and presence of pathological ulcer findings within the ESD specimen were significantly related to the risk of ESD ulcer recurrence. Although the frequency is low, there is a possibility of ESD ulcer recurrence in patients with H. pylori infection and in patients who undergo ESD for a lesion with ulceration.

Abstract
7 Background: S-1/cisplatin is regarded as one of the standard regimens in Japan by the SPIRITS trial, but cisplatin needs in-hospital treatment for hydration. Phase II data of S-1/DOC showed long survival by outpatient basis. Then we hypothesized that S-1/DOC can be the standard regimen for AGC as outpatient basis. Methods: This is a prospective, multinational randomized phase III study in pts with AGC. Arm A: pts receive S-1 (40mg/m2) twice daily 14 days followed by 7 days rest plus DOC (40 mg/m2) iv on day 1. Arm B: pts receive S-1 28days followed by 14 days rest. Eligibility criteria included measurable/nonmeasurable AGC, age 20–79 and no prior chemotherapy. Primaryendpoint was OS, secondary endpoints were TTP, RR and safety. Based on planned sample size of 628 pts, the trial was designed tohave 90% power to detect an improvement in OS from 300 to 400 days. The accrual period was 3 years with 2 years follow up. Results: 639 pts (Arm A/B, 316/323) were registered and the eligible pts were 635 (314/321).The MST for Arm A was 386 and for Arm B was 327days. The OS for Arm A was not superior to Arm B (log-rank p = 0.1595, HR: 0.88). The TTP for Arm A was 160 and for Arm B was 126 days. The TTP for Arm A was significantly superior to Arm B (log-rank p < 0.0003, HR: 0.74). RR of Arm A was significantly higher than Arm B (36.0%/ 24.4%, p = 0.01). By subset analysis of OS in pre-stratified nonmeasurable AGC, the MST for Arm A was significantly superior to for Arm B (523/335, log-lank p = 0.018). Most common grade 3/4 toxicities were: neutropenia, 31.4% vs. 4.4%; leucopenia, 22.1% vs. 2.5% and anorexia; 15.4% vs. 12.1%. Conclusions: The combination ofS-1/DOC did not meet primary endpoint of OS, but of OS in nonmeasurable group and TTP of the S-1/DOC was significantly superior to that of the S-1 alone. We supposed that recent development of the second-line chemotherapy was influenced to our results. This regimen can be regarded as one of the standard treatments for AGC as outpatient basis.

Abstract
BACKGROUND The pathogenesis of multifocal motor neuropathy (MMN) has yet to be established. MMN patients often carry anti-GM1 IgM antibodies, suggesting an autoimmune process involving complement. Intravenous immunoglobulin (IVIG) is the first line treatment, but its action mechanism is unknown. OBJECTIVE To test whether anti-GM1 IgM antibodies in MMN sera activate complement, inducing and propagating the disease and whether IVIG inhibits complement activation, resulting in clinical improvement. METHODS Sera with anti-GM1 IgM but not IgG or IgA reactivity were obtained from 13 patients with MMN. We tested whether their anti-GM1 IgM antibodies produced complement component deposits on GM1-coated microtiter plates and whether IVIG blocks such deposition. RESULTS C1q, C4b, C3b and C5b-9 were deposited on GM1-coated wells. Their depositions were highly correlated with anti-GM1 IgM antibody titre. IVIG reduced the deposition of these complement components dose-dependently. CONCLUSIONS Anti-GM1 IgM antibodies bound to GM1 and activated complement in vitro. The results together with earlier data from our group suggest that IgM-induced, complement-mediated injury occurs at the nodes of Ranvier in peripheral motor nerves and generates conduction block and muscle weakness. In vitro IVIG inhibited this type of complement activation, suggesting that in vivo, the resulting reduction in membrane attack complex-mediated damage leads to improved muscle strength.

Abstract
Spin diffusion and spin-lattice relaxation in solids containing paramagnetic impurities under influence of a multiple-pulse spin-locking radio-frequency sequence are studied theoretically and experimentally. The diffusion equation obtained provides a clue for determination of the time dependent magnetization. The spin-lattice relaxation time is calculated as a function of the correlation time and multiple-pulse field parameters. From the experimental data the spin diffusion coefficient, the radius of the spin diffusion barrier, and the correlation time for very slow molecular motion in polycrystalline (C(2)F)(n) system are estimated and found to be D∼7.1×10(-12)cm(2)/s, r(c)∼4.8×10(-10)m, and τ(c)∼10.2μs, respectively.

Abstract
Endoscopic mucosal resection (EMR) is a minimally invasive technique for effective treatment of early stage colorectal lesions with no invasive potential. However, the high frequency of local recurrence after piecemeal EMR for large lesions is considered a serious problem. In contrast, endoscopic submucosal dissection (ESD) allows en-bloc resection, irrespective of the lesion's size. ESD has been established as a standard method for the endoscopic removal of early cancers in the upper gastrointestinal tract in Japan. Although the use of ESD for colorectal lesions has been studied clinically, ESD is not yet established as a standard therapeutic method. We define the indications for en-bloc resection, based on extensive clinicopathological analyses, as a laterally spreading tumor (LST) non-granular type (LST-NG) lesion greater than 20 mm and an LST granular (LST-G) type lesion greater than 40 mm. Both of these lesions had a high submucosal invasion rate. Especially, LST-NG type lesions greater than 20 mm are technically difficult to remove completely even by piecemeal EMR and are considered a "definite indication for en-bloc resection". The ESD procedure is undoubtedly an ideal method to achieve en-bloc resection, however, the prevalences of suitable lesions among all neoplastic lesions and among all early cancers were not high (1.0% and 5.0%, respectively). Therefore, it is crucial to master more fundamental therapeutic techniques and have knowledge of surveillance strategy after endoscopic treatment.

Abstract
BACKGROUND AND OBJECTIVE Forsythia detaching factor (FDF) is a putative virulence factor of Tannerella forsythia that induces detachment of adherent cells and interleukin-8 production in human fibroblasts. The objective of the present study was to clarify the relationship between anti-FDF IgG levels in gingival crevicular fluid and the clinical status in patients with periodontitis and in healthy subjects. MATERIAL AND METHODS Gingival crevicular fluid and subgingival plaque samples were obtained from both the diseased and healthy sites of 37 patients with periodontitis and from 30 healthy subjects. Anti-FDF IgG levels were evaluated, and both the fdf gene and T. forsythia 16S ribosomal RNA (rRNA) were detected using the PCR. RESULTS Anti-FDF IgG levels (of both diseased and healthy sites) of patients with periodontitis were significantly higher than those of healthy subjects. Among the patients with periodontitis, anti-FDF IgG levels of healthy sites were significantly higher than those of diseased sites and the levels showed negative correlations with probing pocket depth and clinical attachment level. Among the patients with periodontitis, T. forsythia 16S rRNA was detected in 18 of 37 diseased sites and in 5 of 29 healthy sites, and the fdf gene was detected in 19 of 37 diseased sites and in 7 of 29 healthy sites. By contrast, no healthy subjects were positive for T. forsythia 16S rRNA or the fdf gene. CONCLUSION These data suggest that anti-FDF IgG levels in gingival crevicular fluid are related to the periodontal status.

Abstract
BACKGROUND AND OBJECTIVE Recent studies have revealed that negative regulatory molecules, including interleukin-1 receptor-associated kinase-M (IRAK-M), control the overactivation of Toll-like receptor (TLR) signaling. The role of IRAK-M in human gingival epithelial cells (HGECs), which express TLRs, remains unclear. The present study examined the role of IRAK-M on interleukin-8 and macrophage chemoattractant protein-1 (MCP-1) expression in HGECs stimulated with Porphyromonas gingivalis and TLR ligands. MATERIAL AND METHODS Primary HGECs and an SV40 T-antigen-immortalized HGEC line (epi 4) were stimulated with live or heat-killed P. gingivalis, P. gingivalis lipopolysaccharide or the synthetic lipopeptide PAM(3)CSK(4), and subsequent expression of IRAK-M, interleukin-8 and MCP-1 was evaluated at the mRNA and protein levels. The effects of IRAK-M on interleukin-8 and MCP-1 expressions were evaluated by IRAK-M-specific RNA interference (RNAi)-based loss-of-function assay. RESULTS All tested stimulants up-regulated the expression of IRAK-M in HGECs. The P. gingivalis lipopolysaccharide or PAM(3)CSK(4) increased MCP-1 expression, whereas live P. gingivalis down-regulated the MCP-1 expression in HGECs. However, IRAK-M RNAi increased the expression of MCP-1 irrespective of up- or down-regulation mediated by the respective stimulants. Interleukin-8 gene expression, up-regulated by all tested stimulants, was further enhanced by IRAK-M RNAi. In contrast, IRAK-M RNAi had no effect on the interleukin-8 protein levels, irrespective of the stimulant, indicating that post-translational modification, not IRAK-M, controls interleukin-8 protein expression. CONCLUSION Interleukin-1 receptor-associated kinase-M appeared to have distinct regulatory roles on the interleukin-8 and MCP-1 produced by HGECs, further suggesting an important role for interleukin-8 in the immune response to periodontopathic bacteria.
