Abstract
To improve the function of the polyvinyl alcohol (PVA) bioartificial pancreas, we focused on bone marrow-derived mesenchymal stem cells (MSCs). We examined whether the function of PVA-encapsulated rat islets could be improved by coencapsulation with syngeneic MSCs. We macroencapsulated 1,500 rat islet equivalents (IEQ) with or without 1 × 10(6) MSCs with the use of 3% PVA solution before implantation intraperitoneally into diabetic BALB/c mice. We evaluated the function of the device in vitro (the residual rate, viability, and insulin-releasing function of the islets) and in vivo assessments (blood glucose and serum C-peptide changes after transplantation and glucose tolerance test). Although cultured islets also were destroyed, the shapes of the islets cocultured with MSCs were preserved but not different from encapsulated islets without MSCs. At 96 hours after culture the residual rates of islet recovery among those cocultured with versus without MSCs were 66% versus 39.5%, respectively, (P = .03). On the other hand, there was no significant difference between encapsulated islets with versus without MSCs. Furthermore, the stimulation index of the islets was improved by coculture with MSCs (2.6 ± 0.6 vs 1.4 ± 0.1; P = .03), but no beneficial effects were observed between islets encapsulated with versus without MSCs. The viability of islets cocultured with MSCs was significantly better than that without MSCs (84.2 ± 2.5 vs 73.3 ± 0.9; P = .037), but MSCs did not improve the viability of encapsulated islets. There were no significant differences in blood glucose or serum C-peptide between islets encapsulated with versus without MSCs. The histologic findings showed many degenerative islets and MSCs soon after transplantation. In conclusion, further studies are necessary to develop a novel PVA bioartificial pancreas that can be used with MSCs.

Abstract
A 20-year-old Japanese woman with systemic sclerosis was evaluated for the progressive aggravation of chest pain, palpitations and dyspnea. Cardiac magnetic resonance imaging revealed diffuse wall thinning, segmental dyskinesis and late gadolinium enhancement of the right ventricular (RV) myocardium. Cardiac catheterization demonstrated no pulmonary hypertension. 24-hour electrocardiography monitoring showed non-sustained ventricular tachycardia (VT). Pulseless VT was induced via programmed ventricular stimulation. An endomyocardial biopsy of the right side of the interventricular septum was performed, the histological specimen of which demonstrated massive myocardial atrophy and fibro-fatty replacement with predominant fibrotic changes. The patient was ultimately diagnosed with arrhythmogenic RV cardiomyopathy.

Abstract
Abstract
Background: Among women who take 2-5 years of adjuvant endocrine therapy, more than half of all recurrences of hormone receptor (HR) positive breast cancer occur after the first 5 years. Data from large clinical trials including ATLAS, aTTom,MA17 and NSABP B-30 support extending tamoxifen or aromatase inhibitor beyond 5 year for women with HR positive breast cancer. For decision making according to extending endocrine therapy, the information of the risk of late recurrence is quietly important.
Patients and methods: In order to determine ten year disease free survival (DFS) rates, we reviewed medical records and database of patients who were treated at National Kyushu Cancer Center between 1990 and 2001. Among seven hundred fifty seven patients with HR positive breast cancer, 550 received tamoxifen for 2-5 years. Eighty eight patients had recurrence within five years after surgery, and 13 were not followed, with 83.5% of 5-year DFS after surgery. Remaining four hundred twenty six had no recurrence at the time of 5 years after surgery. To evaluate the risk of late recurrence, we analyzed the long-term results in association with clinicopathological factors for these 426 patients.
Results: Four hundred twenty six patients had 87.1% of 10-year DFS rate. According to lymph node metastasis (N), ten year DFS rates were 91.4% for 275 N-negative and 80.0% for 155 N-positive cases (P = 0.0037). As for the number of lymph node metastasis, 10-year DFS rates were 82.5%, 74.2%, and 79.1% for N1-3, N4-9, N>9, respectively. Tumor size was correlated with the prognosis, and 10-year DFS rates were 91.5% for 167 T1 (≤2 cm), 86.9% for T2 (2-5 cm), and 67.9% for T3 (>5cm) (P = 0.0334). There were no significant differences between grade and prognosis, and 10-year DFS rates of grade 1, 2 and 3 were 88.9%, 89.8%, and 96.8%, respectively (p = 0.3914). Considering the age at 5 years after surgery, no significant differences were observed as for late recurrence. Ten-year DFS rates of 96 cases of age under 50, 227 between 50 and 65, 113 over 65 was 89.4%, 85.1%, and 86.0%, respectively. Ten-year DFS rates of N-negative and N-positive were 94.3% and 81.2%, 88.1% and 80.1%, and 90.4% and 76.7% for these age criteria, respectively.
Conclusion: Patients with HR positive breast cancer require optimal information for decision making whether to receive extending endocrine therapy or not. Our data demonstrated the risk of late recurrence in relation to clinic-pathological factors, which may support the consideration about extending endocrine therapy. Relatively high risks of late recurrence with over 10% of 10 year DFS rates are there in cases with N-positive or T2-3 HR positive breast cancer.

Abstract
Abstract
Objective: Post-mastectomy radiotherapy (PMRT) is strongly recommended for breast cancer patients with 1 to 3 axillary lymph node metastasis (N1-3) in NCCN guidelines Version 3.2013 (category 1), whereas the indication of that treatment should be considered individually according to the risk of local recurrence (St Gallen Consensus Meeting 2013). In order to support decision making of PMRT, we evaluated the risk factors of local recurrence after mastectomy.
Patients and methods: We reviewed retrospectively 2422 cases with Stage I – III primary breast cancer receiving surgery at National Kyushu Cancer Center between 2000 and 2009. Seven hundred seventy six of them underwent mastectomy, and 547 of them received no PMRT. We analyzed the risk of local recurrence in relation to clinicopathologial factors, the status of hormone receptor and HER2, especially in cases with N1-3.
Results: Among 547 cases with no PMRT, there were 364 cases with no LN metastasis (N0), 146 N1-3, and 37 N≥4, and 5-year local disease free survival (DFS) rates were 97.0%, 91.2%, and 73.4%, respectively. In N1-3 (146) cases who underwent no post-operative regional radiotherapies, the 5-year DFS in extent of lymph vessel infiltration (ly) were: ly0 was 97.9% (50) and ly1-3 was 87.9% (92) (ly unknown were 4). In the ly0 cases, the 5-year local DFSs were 100% in grade 2 and 85.7% in grade 3; 100% in ER positive and 90.0% in ER negative; 90.9% in HER2 positive and 100% in HER2 negative. Those in the cases of ly1-3 were 94.5% and 73.4%, 88.7% and 76.6%, and 91.0% and 64.3%, respectively.
Conclusion: In patients with N1-3 breast cancer, the risk of local recurrence after mastectomy was significantly related to grade, extent of lymph vessel infiltration, ER and HER2. PMRT could be omitted in case with ly0,additionaly with grade 1-2, ER positive and HER2 negative. The remaining cases have the risk of local recurrence over 10%, if they don't receive PMRT, in which the indication of PMRT should be considered.

Abstract
OBJECTIVE Bacterial lipopolysaccharide (LPS) can induce inflammatory bone loss such as periodontal disease. The formation of osteoclasts depends on macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor kb ligand (RANKL). It has recently been reported that administration of an antibody of the M-CSF receptor c-Fms completely blocked osteoclastogenesis and bone erosion induced by LPS in mouse calvaria. In this study, the effect of antibody against c-Fms in the mouse periodontitis model by injection of LPS was investigated. MATERIALS AND METHODS C57BL6/J mice were injected with LPS and anti-c-Fms antibody into the mesial gingiva of the first molar in the left mandible. Histological sections of periodontal tissue were stained for tartrate-resistant acid phosphatase, and osteoclast numbers and ratio of alveolar bone resorption determined. RESULTS The number of osteoclasts and ratio of alveolar bone resorption in mice administered both LPS and anti-c-Fms antibody was lower than those in mice administered LPS alone. The expression of RANKL receptor, RANK, was inhibited by the anti-c-Fms antibody in periodontal tissue. CONCLUSION M-CSF and/or its receptor are potential therapeutic targets for the treatment of bone resorption, caused by LPS, in periodontitis. Injection of an anti-c-Fms antibody might be useful for inhibition of pathological bone resorption in periodontitis.

Abstract
PURPOSE An isolated perfused pig heart model has recently been proposed for the development of novel methods in standard clinical magnetic resonance (MR) scanners. The original set-up required the electrical system to be within the safe part of the MR-room, which introduced significant background noise. The purpose of the current work was to refine the system to overcome this limitation so that all electrical parts are completely outside the scanner room. METHODS Four pig hearts were explanted under terminal anaesthesia from large white cross landrace pigs. All hearts underwent cardiovascular magnetic resonance (CMR) scanning in the MR part of a novel combined 3T MR and x-ray fluoroscopy (XMR) suite. CMR scanning included real-time k-t SENSE functional imaging, k-t SENSE accelerated perfusion imaging and late gadolinium enhancement imaging. Interference with image quality was assessed by spurious echo imaging and compared to noise levels acquired while operating the electrical parts within the scanner room. RESULTS Imaging was performed successfully in all hearts. The system proved suitable for isolated heart perfusion in a novel 3T XMR suite. No significant additional noise was introduced into the scanner room by our set-up. CONCLUSIONS We have substantially improved a previous version of an isolated perfused pig heart model and made it applicable for MR imaging in a state of the art clinical 3T XMR imaging suite. The use of this system should aid novel CMR sequence development and translation into clinical practice.

Abstract
Abstract
Background: In SABCS 2009, we reported that the high level of serum anti-p53 antibody titers was associated with response to preoperative chemotherapy in cases with primary breast cancer (SABCS 2009). Prognostic meaning of pathological complete response (pCR) after preoperative chemotherapy differs among various subtype, and there is a close relationship between pCR and prognosis in cases with HER2 positive or triple negative disease. The aim of this study is to evaluate the association between the high level of serum anti-p53 antibody titers and pCR in patients with HER2-positive or triple negative breast cancer.
Patients and Methods: In this study, we analyzed 196 women with operable early stage breast cancer (T1-T3, N0-1) treated with preoperative chemotherapy and definitive curative surgery since 2002 to 2011. All of the patients received four cycles of FEC (fluorouracil 500 mg/m2, epirubicin 100 mg/m2, cyclophosphamide 500 mg/m2 q3w) followed by four cycles of docetaxel (75 mg/m2 q3w). The serum anti-p53 antibody titers were assessed by ELISA with the anti-p53 EIA Kit II (MESACUP anti-53 Test: MBL) in the pre-treatment serum samples. The test's cut-off value was determined to be 1.3 IU/ml based on reference distribution in healthy control individuals. The association between serum anti-p53 antibody titers and pCR was analyzed.
Results: The subtype of tumors of 196 patients were classified to 86 of ER+/HER2−, 24 of ER+/HER2+, 29 of ER−/HER2+ and 57 of ER−/HER2−. The pCR was achieved 49 of 196 patients (25%). The pCR rate were 7%(6/86), 33%(8/24), 48%(14/29) and 37%(21/57) in the subtype of ER+/HER2−, ER+/HER2+, ER−/HER2+ and ER−/HER2− respectively. The range of serum anti-p53 antibody titers in the serum samples of 196 patients was between 0.40 and 5610 (the median was 0.40 and the average was 85.2). Excluding 86 cases with ER+/HER2−, relationship between serum anti-p53 antibody titers and pCR was evaluated. According to serum anti-p53 antibody titers with the patients of pCR, cut-off value of serum anti-p53 antibody titers was set to be 6 IU/ml. The pCR was observed in nine of 12 cases (75%) with high serum anti-p53 antibody titers, which was significantly higher than those with low titers (35%: 34/98; p = 0.01). Multivariate analysis showed that the only high anti-p53 antibody titer was an independent predictive factor for pCR due to preoperative chemotherapy (p = 0.01).
Conclusion: p53 mutation analysis using serum anti-p53 antibody titers might be a useful predictive test for response to preoperative chemotherapy in patients especially with HER2 positive or triple negative breast cancer.
