Abstract
Aims/Introduction To explore the relationships between periodontitis and microvascular complications as well as glycemic control in type 2 diabetes patients. Materials and Methods This multicenter, hospital‐based, cross‐sectional study included 620 patients with type 2 diabetes. We compared the prevalence and severity of periodontitis between patients with ≥1 microvascular complication and those without microvascular complications. We also compared the prevalence and severity of periodontitis among patients with different degrees of glycemic control. Results After adjusting for confounding factors, multiple logistic regression analysis showed that the severity of periodontitis was significantly associated with the number of microvascular complications (odds ratio 1.3, 95% confidence interval 1.1–1.6), glycated hemoglobin ≥8.0% (64 mmol/mol; odds ratio 1.6; 95% confidence interval 1.1–2.3), and older age (≥50 years; odds ratio 1.7; 95% confidence interval 1.1–2.6). However, the prevalence of periodontitis was not significantly associated with the number of microvascular complications, but was associated with male sex, high glycated hemoglobin (≥8.0% [64 mmol/mol]), older age (≥40 years), longer duration of diabetes (≥15 years) and fewer teeth (≤25). Furthermore, propensity score matching for age, sex, diabetes duration and glycated hemoglobin showed that the incidence of severe periodontitis was significantly higher among patients with microvascular complications than among those without microvascular complications (P < 0.05). Conclusions The number of microvascular complications is a risk factor for more severe periodontitis in patients with type 2 diabetes, whereas poor glycemic control is a risk factor for increased prevalence and severity of periodontitis.

Abstract
BACKGROUND Differences in the predictive value of daytime systolic blood pressure (SBP) and night-time SBP by ambulatory blood pressure monitoring on renal outcomes have not been fully investigated in chronic kidney disease (CKD) patients. This study compared the prognostic value between daytime and night-time SBP on renal outcomes in CKD.Methods and Results:This prospective observational study included 421 patients. The composite renal endpoint was endstage renal disease (ESRD) or death. Cox models were used to determine associations of daytime and night-time SBP with renal outcomes. There were 150 renal events (ESRD, 130; death, 20). Multivariable Cox analyses demonstrated that hazard ratios (HRs) [95% confidence interval (CI)] for composite renal outcomes of every 10-mmHg increase in daytime and night-time SBP levels were 1.13 (1.02-1.26) (P=0.02) and 1.15 (1.05-1.27) (P<0.01), respectively. In addition, compared with the 1st daytime or night-time SBP quartile, HRs (95% CI) for outcomes in the 2nd, 3rd, and 4th quartiles were: daytime SBP, 1.25 (0.70-2.25), 1.09 (0.61-1.94), and 1.58 (0.88-2.85; P=0.13) (P for trend=0.16); night-time SBP, 1.09 (0.61-1.96), 1.31 (0.76-2.28), and 1.82 (1.00-3.30; P=0.049) (P for trend=0.03), respectively. CONCLUSIONS Night-time SBP appeared superior to daytime SBP for predicting renal outcomes in this population of patients.

Abstract
OBJECTIVE Ameloblastoma (AM) shows locally invasive behaviour. However, biological investigations regarding regulation of gene expression associated with AM pathological features are difficult to perform, because AM cells can be passaged for a few generations due to senescence. We report a newly established immortalized AM cell line, AMB cells, by transfection with human telomerase reverse transcriptase (hTERT). Furthermore, we examined whether TNF-α modulates bone resorption-related genes, IL-6 and MMP-9 in cooperation with TGF-β or IFN-γ. MATERIALS AND METHODS Following transfection of an hTERT expression vector into AM cells using a non-viral method, the effects of cytokines on the expressions of IL-6 and MMP-9 mRNA were examined using real-time PCR. TNF-α-induced NF-κB activity was examined by western blotting and transcription factor assays. RESULTS AMB cells continued to grow for more than 100 population doublings. Stimulation with TNF-α increased IL-6 and MMP-9 mRNA expressions, as well as NF-κB activation. Furthermore, TGF-β and IFN-γ dramatically increased TNF-α-mediated expressions of MMP-9 and IL-6 mRNA, respectively, while those responses were suppressed by NF-κB inhibitor. CONCLUSION We established an immortalized AM cell line by hTERT transfection. TNF-α-mediated regulation of MMP-9 and IL-6 via NF-κB may play an important role in the pathological behaviour of AMs, such as bone resorption.

Abstract
OBJECTIVE In patients with preserved kidney function, a positive association of fibroblast growth factor 23 (FGF23) with serum uric acid (SUA) has been reported; however, the relationship in overall chronic kidney disease (CKD) patients has not been investigated. No report has examined the relationship between FGF23 and uric acid clearance (CUA). The aim of the present study was to determine whether FGF23 is independently associated with urate metabolism in patients with CKD stages 1-5. MATERIALS AND METHODS In this cross-sectional study, 537 CKD patients were enrolled. SUA, CUA, FGF23, parathyroid hormone (PTH), and 1,25-dihydroxyvitamin D (1,25(OH)2D) were measured. Multivariable linear regression analysis was applied to determine independent factors associated with SUA or CUA. RESULTS In all patients, both SUA and CUA were independently associated with male sex, use of diuretics, use of uric acid-lowering agents, estimated glomerular filtration rate, and log FGF23 (β=0.29, P<0.01 for SUA; β=-0.11, P<0.01 for CUA), but not with log PTH or log 1,25(OH)2D. Dyslipidemia and diabetes were also independent factors for SUA and CUA, respectively. In multivariable analyses by sex, log FGF23 was associated with SUA in both sexes (β=0.32, P<0.01 in males vs. β=0.20, P=0.02 in females). Conversely, log FGF23 was independently associated with CUA in males (β=-0.15, P<0.01), but not in females (β=-0.09, P=0.17). CONCLUSIONS FGF23 was independently associated with urate metabolism in this population of CKD patients. FGF23 might also have a stronger association with urate metabolism in males compared with females.

Abstract
The records of 70 patients with oral cancer who were treated at a single institution between 2008 and 2014 were reviewed. The body temperature, white blood cell count, and C-reactive protein (CRP) levels were compared between those who had received preoperative oral care (oral care group) and those who had not received any (non-oral care group). When the patients were divided into those who underwent minimally invasive surgery and those who underwent severely invasive surgery, the mean CRP level in the early postoperative period was lower in the oral care group as compared with the non-oral care group in those who underwent minimally invasive surgery as well as those who underwent severely invasive surgery. However, the mean CRP level was most evidently reduced in the severely invasive group on days 1 and 3-5. However, no significant differences were observed with regard to the percentage of postoperative infectious complications (for example, surgical site infection, anastomotic leak and pneumonia) between the oral care (13.6%) and non-oral care (20.8%) groups, though a reduced prevalence of postoperative complications following preoperative oral care was noted. The results of the present study suggest that preoperative oral care can decrease inflammation during the early postoperative stage in patients with oral cancer who undergo severely invasive surgery.

Abstract
The report is the first of purification, overproduction, and characterization of a unique γ-butyrobetainyl CoA synthetase from soil-isolated Agrobacterium sp. 525a. The primary structure of the enzyme shares 70-95% identity with those of ATP-dependent microbial acyl-CoA synthetases of the Rhizobiaceae family. As distinctive characteristics of the enzyme of this study, ADP was released in the catalytic reaction process, whereas many acyl CoA synthetases are annotated as an AMP-forming enzyme. The apparent Km values for γ-butyrobetaine, CoA, and ATP were, respectively, 0.69, 0.02, and 0.24 mM.

Abstract
We present a statistical analysis of the first four seasons from a "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage of 8 deg2 of the Galactic bulge by the OGLE, MOA, and Wise microlensing surveys. During this period, 224 microlensing events were observed by all three groups. Over 12% of the events showed a deviation from single-lens microlensing, and for ~1/3 of those the anomaly is likely caused by a planetary companion. For each of the 224 events we have performed numerical ray-tracing simulations to calculate the detection efficiency of possible companions as a function of companion-to-host mass ratio and separation. Accounting for the detection efficiency, we find that 55 - 22 + 34 % of microlensed stars host a snowline planet. Moreover, we find that Neptunes-mass planets are ~ 10 times more common than Jupiter-mass planets. The companion-to-host mass ratio distribution shows a deficit at q ~ 10-2, separating the distribution into two companion populations, analogous to the stellar-companion and planet populations, seen in radial-velocity surveys around solar-like stars. Our survey, however, which probes mainly lower-mass stars, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.

Abstract
The aim of the present study was to examine whether interconnected porous hydroxyapatite ceramics (IP-CHA) could be used as bone substitute for implant treatment in reconstructive surgery. We firstly assessed if surround of the titanium surface placed into granular or block-type IP-CHA can observe new bone formation in a rabbit bone defect model. Subsequently, osseointegration and stability of titanium implant inserted into block-type IP-CHA was investigated in a rabbit onlay graft model. Direct contact between new bone and the surface of the titanium in granular- or block-type IP-CHA was found in a rabbit bone defect. Further, new bone formation was found in direct contact with the implant surface in the block-type IP-CHA in an onlay graft model, and the implant stability quotient (ISQ) values were significantly increased after surgery. Therefore, IP-CHA may be a useful material for implant treatment in reconstructive surgery strategies.

Abstract
OBJECTIVE Serum bilirubin has been reported to be associated with the progression of kidney disease in patients with diabetic nephropathy. Less is known, however, about the relationship between bilirubin and chronic kidney disease (CKD) of other etiologies. This study was designed to clarify whether serum total bilirubin concentration is associated with kidney disease progression in patients with CKD independent of etiology. MATERIALS AND METHODS This prospective observational study enrolled 279 consecutive patients with stages 3-5 CKD. The renal endpoint was the composite of the doubling of serum creatinine or end-stage renal disease requiring dialysis. Patients were divided into three groups by their serum total bilirubin concentrations: ≤0.3 (lowest), 0.4-0.5 (middle), and ≥0.6 (highest) mg/dL. A Cox proportional hazards model was applied to determine the risk factors for poor renal outcome. RESULTS The median follow-up period was 21months. One-hundred and three patients reached renal end points. After multivariable adjustment, a 0.1mg/dL increase in serum bilirubin was associated negatively with poor renal outcome (hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.60-0.87). In addition, after adjustment for confounding factors, including traditional and nontraditional cardiovascular risk factors, the middle (HR 3.14, 95% CI 1.36-8.57) and lowest (HR 4.22, 95% CI 1.81-11.59) bilirubin groups had significantly higher HRs for renal outcome than the highest bilirubin group. CONCLUSIONS Lower serum bilirubin concentration was independently associated with adverse renal outcomes, suggesting that the measurement of serum bilirubin is useful for predicting kidney disease progression in patients with moderate to severe CKD.

Abstract
We report a case of advanced gastric cancer that was successfully treated with second-line chemotherapy followed by curative conversion gastrectomy. The patient was a 71-year-old man. Endoscopic examination revealed a type 3 gastric cancer in the lower third of the stomach. Abdominal computed tomography (CT) revealed multiple lymph node metastases and metastasis to the peritoneal cavity. The clinical diagnosis was cT4N3aP1H0M1(LYM), cStage IV. The patient was treated with S-1 (80 mg/m² on days 1-28, every 6 weeks [q6w]) in November 2009. Temporarily, both the size of the primary lesion and the swelling of the lymph nodes were markedly reduced. However, after 10 courses of chemotherapy, the primary lesion was found to be enlarged again. The patient was then treated with S-1(80 mg/m², on days 1-14, every 6 weeks [q3w]) plus CPT- 11 (150 mg/m² on day 1, q3w) as the second-line chemotherapy. After 8 courses, an abdominal CT showed no peritoneal or lymph node metastases, but gastric endoscopy revealed the presence of a residual primary lesion. After staging laparoscopy, distal gastrectomy with D2 lymphadenectomy was performed. The histological diagnosis was ypT3 (SS) N1M0, Stage IIB. Analysis of the histological features of the primary tumor and peritoneal metastases resulted in their classifications as Grade 1a and Grade 3, respectively. After surgery, there were no serious adverse events. The patient has been in good health without recurrence for over 3 years after surgery.

Abstract
We report a patient with metachronous triple cancer of the hypopharynx, esophagus, and tongue. A 37-year-old man with hypopharyngeal cancer underwent hypopharyngolaryngectomy and cervical lymphadenectomy in 1999. Submental lymphadenectomy following adjuvant radiotherapy was performed for lymph node recurrence in 2000. The patient then underwent esophagectomy for esophageal cancer in 2004. Subsequently, the patient underwent 2 partial resections and 1 subtotal resection of the tongue for tongue cancer in 2005, 2007, and 2008, respectively. The pathological findings for each cancer were squamous cell carcinoma. Two rounds of radiotherapy were performed for bone metastasis of the esophageal cancer and for the local recurrence of the tongue cancer. A total of 7 lines of chemotherapy, including superselective arterial infusion chemotherapy, were administered to treat the recurrences. The patient died in 2013, but he showed long-term survival of 13 years from the first operation owing to the multimodality treatment.

PURPOSE The efficacy of chemotherapy for advanced or recurrent gastric cancer in patients who were aged over 75 years was investigated. MATERIALS AND METHODS Progression free survival (PFS) and overall survival (OS) of advanced gastric cancer patients who received first-line chemotherapy with TS-1 plus cisplatin or TS-1 in our hospital from 2009 to 2013 were determined. The patients were divided into two groups: H and L. H group patients were aged over 75 years, and L group patients were aged less than 75 years. RESULTS Median PFS and median OS of patients in the H and L groups who received TS-1 plus cisplatin chemotherapy were not significantly different. PFS was 77[range, 13-211] days and 139[range, 53-211]days for the H and L groups, respectively(p=0.141), while OS was 523[range, 22-1,030] days and 402 [range, 322-623] days, respectively (p=0.620). Similarly, median PFS and median OS of patients who received TS-1 chemotherapy were not significantly different between the H and L groups. PFS was 103[range, 51-156]days and 152.5[range, 85-278]days for the H and L groups, respectively (p=0.230), while OS was 414 [range, 224-714]days and 605[range, 452-1,077] days, respectively ( p=0.1337). CONCLUSION PFS and OS were not significantly different in younger patients with advanced gastric cancer who received TS-1 plus cisplatin or TS-1 chemotherapy compared to that in similarly treated elderly patients with advanced gastric cancer.

Abstract
BACKGROUND Innate immune response by oral mucosal cells may be the first line of host defense against viral infection. Retinoic acid-inducible gene-I (RIG-I) recognizes viral dsRNA in the cytoplasm, and RIG-I-mediated signaling regulates antiviral type I IFN, and inflammatory chemokine production. Here, we tested the hypothesis that oral mucosal cell participation in host defense against viral infection via RIG-I. METHODS RIG-I expression was detected in immortalized oral keratinocytes (RT7), oral fibroblasts (GT1) using and RT-PCR and immunohistochemistry. RT7 and GT1 were exposed to dsRNA virus mimic Poly I:C-LMW/LyoVec (PLV). Expression of IFN-β and CXCL10 via RIG-I was examined by Real-time RT-PCR and ELISA. Phosphorylation of IRF3 and STAT1 were detected by western blotting. RESULTS RT7 and GT1 constitutively expressed RIG-I in the cytoplasm. Furthermore, PLV increased IFN-β and CXCL10 productions in both RT7 and GT1 via RIG-I concurrent with phosphorylation of IRF3 and STAT1. PLV-induced CXCL10 production was attenuated by neutralization of IFN-β and blocking of IFN-α/β receptor (IFNAR), indicating primal IFN-β production via the RIG-I-IRF3 axis, which eventually induces CXCL10 production via the IFNAR -STAT1 axis. CONCLUSION We propose that RIG-I in oral keratinocytes and fibroblasts may cumulatively develop host-defense mechanisms against viral infection in oral mucosa.

Abstract
Toll-like receptor (TLR) family members are pattern recognition receptors that are essential in the activation of innate and adaptive immune responses. Submandibular gland epithelial cells (SMGCs) may recognize microbial components through TLRs and be involved in the development of inflammatory reactions in the submandibular glands. Therefore, the functional expression of TLRs in SMGCs was investigated in the present study. The mRNA expression of TLRs in SMGC and whole submandibular tissues was determined by RT-PCR. Subsequently, the effects of various TLR agonists and tumor necrosis factor alpha (TNF-α) on IL-8 production were examined using an ELISA. SMGCs, as well as whole submandibular tissues, expressed TLR1-10 mRNA. Furthermore, interleukin (IL)-8 production in SMGCs was increased by Pam3CSK4 (TLR1/2 agonist), poly I:C (TLR3 agonist), E. coli lipopolysaccharide (LPS; TLR4 agonist), flagellin (TLR5 agonist) and macrophage‑activating lipopeptide (MALP)-2 (TLR2/6 agonist) treatments in a dose‑dependent manner, whereas administration of either imiquimod (TLR7 agonist) or CpG-oligodeoxynucletide (TLR9 agonist) exerted no evident effect. Pam3CSK4, poly I:C, LPS, flagellin and MALP-2 also enhanced TNF‑α‑induced IL-8 production in SMGCs. These findings suggest that innate immune responses against microbial components result in the development of TNF-α-mediated autoimmune inflammatory disease in the submandibular glands.

Abstract
The ankle-brachial blood pressure index (ABPI) has been recognized to have a predictive value for cardiovascular (CV) events and mortality in general or dialysis populations. However, the associations between ABPI and those outcomes have not been fully investigated in predialysis patients. The present study aimed to clarify the relationships between ABPI and both CV events and mortality in Japanese chronic kidney disease (CKD) patients not on dialysis. In this prospective observational study, we enrolled 320 patients with CKD stages 3-5 who were not on dialysis. At baseline, ABPI was examined and a low ABPI was defined as <0.9. CV events and all-cause deaths were examined in each patient. A Cox proportional hazards model was applied to determine the risk factors for CV events, as well as for mortality from CV and all causes. The median follow-up period was 30 months. CV events occurred in 56 patients and all-cause deaths occurred in 48, including 20 CV deaths. Multivariate analysis showed that age and low ABPI were risk factors for CV events. It was demonstrated that age, a history of cerebrovascular disease and low ABPI were determined as independent risk factors for CV mortality. In addition, age, body mass index and low ABPI were independently associated with all-cause mortality. In patients with CKD, low ABPI during the predialysis period is independently associated with poor survival and CV events, suggesting the usefulness of measuring ABPI for predicting CV events and patient survival in CKD.
