Abstract
BACKGROUND AND OBJECTIVE Several studies have shown that diabetes mellitus increases the severity of periodontitis. Conversely, periodontitis has been shown to have an impact on diabetes, although the underlying mechanisms of this are unclear. The aim of this study was to compare the inflammatory response to Porphyromonas gingivalis infection in normal and diabetic mice. MATERIAL AND METHODS Porphyromonas gingivalis were inoculated adjacent to the periosteum, at a point on the midline of the skull located between the ears, in C57BL/6 (normal) and KKAy (diabetic) mice. After induction, the levels of tumor necrosis factor-alpha, interleukin-6 and adiponectin in the mice were measured using real-time polymerase chain reaction and enzyme-linked immunosorbent assay. RESULTS The KKAy mice showed significant increases in blood glucose, serum tumor necrosis factor-alpha and interleukin-6 levels after inoculation with Porphyromonas gingivalis, and a significant decrease in adiponectin to 35.7%. Similar results were observed at the mRNA level in liver and visceral adipose tissue. CONCLUSION These observations suggest that tumor necrosis factor-alpha, interleukin-6 and adiponectin are an integral part of the link between diabetes mellitus and Porphyromonas gingivalis infection.

Abstract
The current status of replacement therapy for haemophilia and the role played by nurses in Japan were investigated at 16 facilities (17 specialties) each providing care to 20 or more haemophilia A or B patients without inhibitor. The questionnaire was mailed to the nurse or physician in charge of haemophilia at each facility in August 2006, asking the nurse to fill in the questionnaire. Responses were collected on 1318 patients (haemophilia A: 1078 patients; haemophilia B: 240 patients). About 70% of these patients were reported to be severe haemophilia A or B. Overall, 26% were receiving regular prophylaxis while 74% received on-demand therapy with or without temporary prophylaxis before special events. The percentage of patients receiving primary prophylaxis was only 2%. The percentage of adherence to prophylaxis decreased with age (lowest at age 19-29) but this percentage for each age group in Japan was higher than that in the western countries. Of the nurses working at the facilities surveyed, 88% considered prophylaxis as an optimal therapy for severe haemophilia patients, although the percentage of patients receiving prophylaxis for the entire population surveyed was lower than that in the western countries. The main factor precluding introduction of prophylaxis was 'difficulty in venous access' for infants and small children. On the other hand, 'unwillingness of family members' and 'poor adherence' were the main factors precluding introduction of this therapy for those aged over 6 years.

Abstract
OBJECTIVE To evaluate the vascular response at 9 months after zotarolimus-eluting stent (ZES; Endeavor) implantation using optical coherence tomography (OCT). These findings were compared with those after implantation of a sirolimus-eluting stent (SES; Cypher Select). DESIGN Cross-sectional observational study with prospective OCT registry. SETTING Nine months after ZES or SES implantation. PATIENTS AND METHODS A total of 68 patients (32 ZES and 36 SES) underwent OCT at 9 months after stent implantation. The neointima hyperplasia (NIH) thickness inside each strut and percentage of NIH area at every 1 mm cross section were measured. MAIN OUTCOME MEASUREMENT The degree of neointimal coverage and the prevalence of malapposition at 9 months after ZES and SES implantation using OCT. RESULTS The mean (SD) NIH thickness (251.2 (110.0) mum vs 85.5 (53.3) mum, p<0.001) and percentage of NIH area (27.9 (9.1)% vs 11.2 (7.1)%, p<0.001) were significantly greater in ZES than in SES. The prevalence of uncovered strut as well as malapposed strut was significantly lower in ZES than in SES (0.3% vs 12.3%, p<0.001 and 0.08% vs 2.6%, p<0.001). Thrombus was not observed in ZES (0.0% in ZES vs 27.8% in SES, p = 0.001). CONCLUSIONS Neointimal coverage in ZES was almost complete and malapposition was very rare at 9-months' follow-up.

Abstract
e16536 Background: In addition to polymorphisms of UGT1A1*28, UGT1A1*6 has been recognized as a risk factor for severe irinotecal-related toxicities. We have conducted an UGT1A1 genotype-based dose-escalation study for recurrent and refractory gynecologic cancer patients (pts) treated with combination with irinotecan and cisplatin (CPT-P). Methods: Pts eligible for this study had histologically confirmed uterine cancer or ovarian cancer, who received CPT-P; a course of therapy consisting of 40–80 mg/m2 of irinotecan on days 1, 8, and 15 and 60 mg/m2 of cisplatin on day 1, q4weeks. Polymorphisms of UGT1A1*28 and *6 were analyzed and the pts were categorized into three groups (wild-type, hetoro-type, and homo-type). Pharmacokinetics of CPT-11, SN-38, SN-38 glucuronide (SN-38G), and platinums were analyzed according to the UGT1A1 genotyping. Results: During August 2008 and December 2008, 17 pts were enrolled in this study; 12 ovarian cancers and 5 uterine cancers. Genotypes of UGT1A1 were wild in 9 pts (53%), *28 in 4 pts (24%), *6 in 3 pts (18%), *6/*6 in 1 pt (6%). At the starting doses of irinotecan (60 mg/m2 for wild-type and 40 mg/m2 for hetero-/homo-type), dose limiting toxicities were observed in two of six wild-type cases and one of six hetero-type cases. Pharmacokinetic analyses revealed hetero-type cases were associated with lower area under time-concentartion curve (AUC) SN-38G to SN-38 (AUCSN-38G/AUCSN-38) compared with wild-type cases (p = 0.02), however, there was no significant difference of AUCSN-38at the starting dose. Additionally, AUC of platinum was slightly higher in hetero-type cases in comparison with wild-type cases (p = 0.04). Pharmacokinetics of the drugs were similar between *28 and *6 cases. Conclusions: The present study indicated clinical significance of UGT1A1 genotyping upon pharmcokinetics of not only SN-38G/SN-38 but also platinum. In addition to UGT1A1*28, UGT1A1*6 was a key candidate to influence the pharmacokinetics of CPT-P regimen in gynecologic cancer patients. No significant financial relationships to disclose.

Abstract
5547 Background: Vascular endothelial growth factor (VEGF) plays a central role in tumor angiogenesis and is regarded a promising therapeutic target. Bevacizumab (A) has significant antitumor activity in combination with cytotoxic agents. Currently, pegylated liposomal doxorubicin (D) is provided as one of the standard treatment options in recurrent ovarian cancer. Thus, we attempted to determine effects in combination of A and D for heavily pretreated patients with recurrent or progressed ovarian cancer. Methods: Twenty-two patients with heavily pretreated (more than one regimen or more than 6 cycles by paclitaxerl and carboplatin) received at least more than 3 cycles of weekly A-D consisting of A: 2 mg/kg and D: 10 mg/m2 (3 weeks, one week rest). The primary endpoint was response according to CA 125 and response evaluation criteria in solid tumor (RECIST) criteria. Results: Of 22 patients evaluable for CA 125 response, 7 (32%) had a response (decrease of >50%), and 8 (36%) patients had not progressed (doubling of CA 125) following 6 months on treatment. In RECIST evaluation, 2 (9%) patients had complete remission (CR) and 6 (27%) had partial remission (PR), resulting in 55% clinical benefit rate (CBR). Progression free interval (PFI) showed more than 6 months. Any hematological adverse effect was not observed in the present study. Gastrointestinal perforation was observed in only one case and was conservatively treated. Although nasal bleeding was frequently observed, no treatment was required. A induced hypertension was also observed and manageable. Hand-foot syndrome seemed due to D was seen in 3 of 22 patients and treatment was required in only one case. Conclusions: B seemed to enhance effect of D. This is the first study of weekly A-D in heavily pretreated ovarian cancer patients. Weekly A-D warrants further clinical study in such clinical settings. No significant financial relationships to disclose.

Abstract
The most common neoplasms of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma (CCC) is mostly derived from the ovary and often associated with endometriosis. We describe the clinicopathologic features of two cases diagnosed as CCC of the peritoneum origin. Case 1, a 53-year-old woman, presented with upper abdominal and pelvic tumors. Case 2, a 66-year-old woman, presented with massive ascites and abdominal tumor. The ovaries and uterine endometrium of these cases were not affected, and the tumors were diagnosed as Stage IIIc CCC of the peritoneum origin. Pathologically, endometriosis was not observed in either case. Adjuvant chemotherapy using irinotecan and cisplatin was effective in one case. The cases and a review of the literature suggested that residual tumor volume size determines the survival of these patients, and that the tumors show resistance to conventional platinum-based chemotherapy.

Abstract
Zinc fortification of milk or soft drinks is usually used to combat zinc deficiencies in developing countries. Water-soluble zinc compounds, such as zinc sulfate or zinc citrate, are better absorbed but have an unacceptable taste. A micronised, dispersible zinc oxide (MDZnO), which does not have such a problem concerning taste, had higher solubility compared to ZnO (zinc oxide) in an artificial gastric solution. MDZnO was tested for its bioavailability using zinc-deficient Wistar rats. Prior to the experiment, rats were fed zinc-deficient diet for 3 wk and were orally administered control (distilled water) or zinc solutions (ZnO, ZnO+L-histidine (His), MDZnO, MDZnO+His, 1 mg zinc/kg or 3.2 mg His/kg body weight). Compared to ZnO, MDZnO showed a lag in peak time and a lengthy period of continued high plasma zinc concentration after the single oral administration of zinc compounds. Addition of His to MDZnO elevated serum zinc concentration. Serum zinc concentration (area under the curve) in rats administered MDZnO with His was significantly higher than in rats administered distilled water (p<0.05). Liver zinc level was significantly higher in rats administered MDZnO with His compared with control rats (p<0.05), although the level was not affected by the administration with ZnO alone, ZnO+His, or MDZnO alone. In conclusion, the solubility of ZnO was elevated by the micronised dispersion tecnique and an in vivo study using zinc-deficient rats confirmed that its bioavailability was significantly improved compared to ZnO and the coadministration of His additively enhanced the bioavailability of MDZnO.

Abstract
Several studies have reported that ovarian clear-cell adenocarcinoma can be derived from endometriosis. Although the clear-cell adenofibroma (CCAF), a major form of benign and borderline ovarian clear-cell tumour, has been suggested as another precursor for clear-cell adenocarcinoma (CCA), there is no supportive genetic evidence for this presumption. To examine the genetic linkage between CCAF and CCA of the ovary, we conducted allelotype analysis for both CCAF and adjacent CCA components in 14 cases of CCA associated with benign CCAF and/or borderline CCAF. DNA isolated from laser-microdissected tissue was subjected to polymerase chain reaction and analysis for loss of heterozygosity (LOH), using 17 polymorphic markers located on 11 chromosomal arms: 1p, 5q, 8p, 9p, 9q, 10q, 11q, 13q, 18q, 19p and 22q. For all informative loci, the frequency of LOH in adenocarcinoma was 49% (54/110 loci), and was significantly higher than those in the components of benign CCAF (22%, 20/92 loci) and borderline CCAF (30%, 25/83 loci) (chi(2) test; p<0.05, respectively). The concordance rate in allelic patterns at all informative loci was 74% between benign CCAF and adenocarcinoma components, 81% between borderline CCAF and adenocarcinoma components, and 95% between benign CCAF and borderline CCAF components. Furthermore, between CCAF and adenocarcinoma components, an identical LOH pattern, involving the same alleles, was found in 13 (93%) of 14 cases at one or more chromosomal loci, and estimation of probability indicated that these events were very unlikely to have occurred by chance. Among the markers examined, LOHs on 5q, 10q and 22q were frequent in both CCAF and adenocarcinoma components, whereas LOHs on 1p and 13q were rare in CCAF components but frequent in adenocarcinoma components. These findings suggest that CCAF can be a clonal precursor for ovarian clear-cell adenocarcinoma.

Abstract
Clear cell carcinoma (CCC) of the ovary has been recognized to show resistance to anticancer agents in the first-line chemotherapy. Our aim was to evaluate the effect of second-line chemotherapy in a retrospective study. A total of 75 patients diagnosed with CCC and treated between 1992 and 2002 in collaborating hospitals were reviewed. Criteria for the patients' enrollment were 1) diagnosis of pure-type CCC at the initial operation, 2) treatment after one systemic postoperative chemotherapy, 3) measurable recurrent or refractory tumor, 4) at least two cycles of second-line chemotherapy and assessable for the response, and 5) adequate clinical information. Regimens of first-line chemotherapy were conventional platinum-based therapy in 33 cases, paclitaxel plus platinum in 24 cases, irinotecan plus platinum in 9 cases, and irinotecan plus mitomycin C in 7 cases. Treatment-free periods were more than 6 months in 24 cases (group A) and less than 6 months in 51 cases (group B). In group A, response was observed in two cases (8%): one with conventional platinum therapy and another with irinotecan plus platinum. In group B, three cases (6%) responded: two with platinum plus etoposide and one case with irinotecan plus platinum. Median overall survival was 16 months in group A and 7 months in group B (P = 0.04). These findings suggest recurrent or resistant CCC is extremely chemoresistant, and there is only small benefit of long treatment-free period in CCC patients. Another strategy including molecular-targeting therapy is warranted for the treatment of recurrent or refractory CCC.

Abstract
BACKGROUND Intersphincteric resection (ISR) is the ultimate sphincter-preserving operation for very low rectal cancer. The aim of this study was to assess defaecatory function after ISR in relation to the degree of resection of the internal anal sphincter. METHODS Between 2001 and 2003, 35 consecutive patients with low rectal cancer had curative ISR, categorized as total, subtotal or partial resection of the internal anal sphincter. Defaecatory function was assessed in terms of frequency of bowel movements and continence. Sphincter function was evaluated by manometric study and anorectal sensation testing before surgery and 3, 6 and 12 months afterwards. RESULTS Defaecatory function was satisfactory after ISR; 34 of 35 patients were grossly continent. The maximum resting anal canal pressure fell after all three procedures. Patients who had total ISR had reduced anal canal sensation at 3 months, but this had improved by 12 months after surgery. CONCLUSION These functional results suggest that ISR should be considered as an alternative to abdominoperineal resection for low rectal cancer. However, as the outcome for continence is worse after total ISR than subtotal or partial ISR, the indication for total ISR should strictly take into account the preoperative sphincter function.

Abstract
UNLABELLED Gastro-esophageal reflux disease (GERD) is associated with a decreased salivary flow as well as gastric acid production. This study therefore aimed to investigate functional disorders of salivary glands in patients with GERD. METHODS Thirty-one consecutive patients with GERD underwent salivary gland scintigraphy. RESULTS If the results defined the optimal cutoff point for determining the decreased salivary secretion as 51 % in parotid glands and 36 % in submandibular glands, a decreased salivary secretion of right parotid gland, left parotid gland, right submandibular gland, and left submandibular gland was found in 39 %, 32 %, 36 %, and 58 %, respectively. Overall, salivary function disorder of at least one major salivary gland was found in 24 patients (78 %) with GERD. There was no difference in the incidence of impaired salivary function between GERD patients with and without erosive esophagitis. Salivary gland function was more frequently diminished than expected in GERD. We concluded that the presence of impaired salivary gland function was considered to be one of risk factors for developing GERD symptoms.

Abstract
The forkhead transcription factor FOXO1, a downstream target of phosphatidylinositol-3-kinase/Akt signalling pathway, regulates cyclic differentiation and apoptosis in normal endometrium, but its role in endometrial carcinogenesis is unknown. Screening of endometrial cancer cell lines demonstrated that FOXO1 is expressed in HEC-1B cells, but not in Ishikawa cells, which in turn highly express the FOXO1 targeting E3-ubiquitin ligase Skp2. FOXO1 transcript levels were also lower in Ishikawa cells and treatment with the proteasomal inhibitor was insufficient to restore expression. Lack of FOXO1 expression in Ishikawa cells was not accounted for by differential promoter methylation or activity, but correlated with increased messenger RNA (mRNA) turnover. Comparative analysis demonstrated that HEC-1B cells proliferate slower, but are more resistant to paclitaxel-mediated cell death than Ishikawa cells, which were partially reversed upon silencing of FOXO1 in HEC-1B cells or its re-expression in Ishikawa cells. We further show that FOXO1 is required for the expression of the growth arrest- and DNA-damage-inducible gene GADD45alpha. Analysis of biopsy samples demonstrated a marked loss of FOXO1 and GADD45alpha mRNA and protein expression in endometrioid endometrial cancer compared to normal endometrium. Together, these observations suggest that loss of FOXO1 perturbs endometrial homeostasis, promotes uncontrolled cell proliferation and increases susceptibility to genotoxic insults.

Abstract
A two-staged, uniaxial magnetoresistive effect has been discovered in SrCo6O11 having a layered hexagonal structure. Conduction electrons and localized Ising spins are in different sublattices but their interpenetration makes the conduction electrons sensitively pick up the stepwise field dependence of magnetization. The stepwise field dependence suggests two competitive interlayer interactions between ferromagnetic Ising-spin layers, i.e., a ferromagnetic nearest-layer interaction and an antiferromagnetic next-nearest-layer interaction. This oxide offers a unique opportunity to study nontrivial interplay between conduction electrons and Ising spins, the coupling of which can be finely controlled by a magnetic field of a few Tesla.

Abstract
Removing electrons from the CuO2 plane of cuprates alters the electronic correlations sufficiently to produce high-temperature superconductivity. Associated with these changes are spectral-weight transfers from the high-energy states of the insulator to low energies. In theory, these should be detectable as an imbalance between the tunneling rate for electron injection and extraction-a tunneling asymmetry. We introduce atomic-resolution tunneling-asymmetry imaging, finding virtually identical phenomena in two lightly hole-doped cuprates: Ca(1.88)Na(0.12)CuO(2)Cl2 and Bi2Sr2Dy(0.2)Ca(0.8)Cu2O(8+delta). Intense spatial variations in tunneling asymmetry occur primarily at the planar oxygen sites; their spatial arrangement forms a Cu-O-Cu bond-centered electronic pattern without long-range order but with 4a(0)-wide unidirectional electronic domains dispersed throughout (a(0): the Cu-O-Cu distance). The emerging picture is then of a partial hole localization within an intrinsic electronic glass evolving, at higher hole densities, into complete delocalization and highest-temperature superconductivity.
