Abstract
BACKGROUND/PURPOSE In oxidative coloring, the hair cuticle layers are not only the penetration pathway for active ingredients but also one of the most important dyeing regions. The dyeing mechanism of oxidative dyes in fine structures of the cuticle remains unclear. To investigate the dyeing behavior of oxidative dyes in fine structures of the cuticle, hair cross-sections were analyzed by nanoscale secondary ion mass spectrometry (NanoSIMS). METHODS The preparation method of hair cross-section for NanoSIMS measurement was improved. Improved hair cross-sections were analyzed using NanoSIMS. RESULTS The cuticle layer thickness of the hair cross-section could be widened. It was confirmed that (12) C(-) ions were more strongly detected from endocuticle than from other fine structures of cuticle. The NanoSIMS (12) C(-) image and hue saturation intensity (HSI) D(-) /(1) H(-) ratio image of the hair, dyed with deuterium-labeled oxidative dye, indicated that the endocuticle had a higher D(-) /(1) H(-) ratio than the other fine structures of the cuticle. It was substantiated that more colored chromophores were fixated in the endocuticle than in other fine structures of the cuticle. CONCLUSION The dyeing behavior of oxidative dyes in fine structures of hair cuticle was substantiated by NanoSIMS analysis using the improved hair cross-section preparation method.

Abstract
In response to sustained damage to a kidney, fibrosis that can be characterized as the deposition of a collagenous matrix occurs and consequently causes chronic kidney failure. Because most animals used in experiments synthesize ascorbic acid (AsA) from glucose, the roles of AsA in fibrotic kidney diseases are largely unknown. Unilateral ureteric obstruction (UUO) mimics the complex pathophysiology of chronic obstructive nephropathy and is an ideal model for the investigation of the roles of AsA in kidney failure. We examined the impact of a deficiency of Akr1a, a gene that encodes aldehyde reductase and is responsible for the production of AsA, on fibrotic damage caused by UUO in mice. Oxidatively modified DNA was elevated in wild-type and Akr1a-deficient kidneys as a result of UUO to a similar extent, and was only slightly suppressed by the administration of AsA. Even though Akrla-deficient mice could produce only about 10% of the AsA produced by wild-type mice, no difference was observed in collagen I synthesis under pathological conditions. The data implied either a low demand for AsA or the presence of another electron donor for collagen I production in the mouse kidney. Next, we attempted to elucidate the potential causes for oxidative damage in kidney cells during the fibrotic change. We found decreases in mitochondrial proteins, particularly in electron transport complexes, at the initial stage of the kidney fibrosis. The data imply that a dysfunction of the mitochondria leads to an elevation of ROS, which results in kidney fibrosis by stimulating cellular transformation to myofibroblasts.

Abstract
The spreading of neurofibrillary tangles (NFTs), intraneuronal aggregates of highly phosphorylated microtubule-associated protein tau, across the human brain is correlated with the cognitive severity of Alzheimer's disease (AD). To identify genes relevant to NFT expansion defined by the Braak stage, we conducted whole-genome exon array analysis with an exploratory sample set consisting of 213 human post-mortem brain tissue specimens from the entorinal, temporal and frontal cortices of 71 brain-donor subjects: Braak NFT stages 0 (N=13), I-II (N=20), III-IV (N=19) and V-VI (N=19). We identified eight genes, RELN, PTGS2, MYO5C, TRIL, DCHS2, GRB14, NPAS4 and PHYHD1, associated with the Braak stage. The expression levels of three genes, PHYHD1, MYO5C and GRB14, exhibited reproducible association on real-time quantitative PCR analysis. In another sample set, including control subjects (N=30), and in patients with late-onset AD (N=37), dementia with Lewy bodies (N=17) and Parkinson disease (N=36), the expression levels of two genes, PHYHD1 and MYO5C, were obviously associated with late-onset AD. Protein-protein interaction network analysis with a public database revealed that PHYHD1 interacts with MYO5C via POT1, and PHYHD1 directly interacts with amyloid beta-peptide 42. It is thus likely that functional failure of PHYHD1 and MYO5C could lead to AD development.

Abstract
Solids and liquids are both known to exhibit Cassie-Baxter states, where a drop or a solid nanoparticle is maintained on top of pillars due to wetting forces. We point out that due to elastic strain, solid nanocrystals exhibit a behavior different from that of liquids. First, the equilibrium Cassie-Baxter state on a single pillar exhibits a spontaneous symmetry breaking due to elastic effects. The second consequence of elasticity is the existence of stable partially impaled states, resulting from a compromise between wetting forces which favor impalement and elastic strain which resists impalement. Based on kinetic Monte Carlo simulations which include elastic strain, we discuss these effects and we propose a global phase diagram for the stability of nanocrystals on nanopillars.

Abstract
Over-expression of alpha-phenol-soluble modulins (PSMs) results in high virulence of community-associated methicillin-resistant Staphylococcus aureus (MRSA). The psm-mec gene, located in the mobile genetic element SCCmec-II, suppresses PSMαs production. Fifty-two patients with MRSA bacteraemia were enrolled. MRSA isolates were evaluated with regard to the psm-mec gene sequence, bacterial virulence, and the minimum inhibitory concentration (MIC) of vancomycin and teicoplanin. Fifty-one MRSA isolates were classified as SCCmec-II, and 10 had one point mutation in the psm-mec promoter. We compared clinical characteristics and outcomes between mutant MRSA and wild-type MRSA. Production of PSMα3 in mutant MRSA was significantly increased, but biofilm formation was suppressed. Wild-type MRSA caused more catheter-related bloodstream infections (30/41 vs. 3/10, p 0.0028), whereas mutant MRSA formed more deep abscesses (4/10 vs. 3/41, p 0.035). Bacteraemia caused by mutant MRSA was associated with reduced 30-day mortality (1/10 vs. 13/41, p 0.25), although this difference was not significant. The MIC90 of teicoplanin was higher for wild-type MRSA (1.5 mg/L vs. 1 mg/L), but the MIC of vancomycin was not different between the two groups. The 30-day mortality of MRSA with a high MIC of teicoplanin (≥1.5 mg/L) was higher than that of strains with a lower MIC (≤0.75 mg/L) (6/10 vs. 6/33, p 0.017). Mutation of the psm-mec promoter contributes to virulence of SCCmec-II MRSA, and the product of psm-mec may determine the clinical characteristics of bacteraemia caused by SCCmec-II MRSA, but it does not affect mortality.

Abstract
Proximal large elastic arteries (ascending aorta and carotid artery) have an important role in buffering the pulsatile pressure generated from the left ventricle, which forwards continuous peripheral blood flow and protects the brain microcirculation from end-organ damage. Although compliance of distal conduit arteries (extremities' arteries) is attenuated by the nitric oxide synthase (NOS) inhibition, it is yet unknown whether compliance of proximal elastic arteries changes by the systemic NOS inhibition. To address this question, we measured central artery compliance in 17 young adults (26±1 years) who underwent intravenous infusions of N(G)-monomethyl-L-arginine (L-NMMA) or saline (placebo) on separate days. Following the systemic NOS inhibition, the mean arterial pressure (MAP), total peripheral resistance and aortic augmentation index were significantly increased. However, carotid artery compliance was not affected significantly (from 0.10±0.01 to 0.11±0.01 mm2) per mmHg) and the β-stiffness index (an index of arterial compliance adjusted for the distending pressure) tended to decrease (from 6.63±0.35 to 6.06±0.42 a.u., P=0.07). These parameters were not altered with saline infusion. Changes in the β-stiffness index tended to correlate negatively with the corresponding changes in MAP (r = -0.31, P=0.07). These results suggest that carotid artery compliance remains unchanged during the systemic NOS inhibition in spite of systemic vasoconstriction.

Abstract
Local failure after definitive chemoradiotherapy (CRT) for stage IB, II, and III esophageal cancer is one of the causes of poor outcome. Endoscopic mucosal resection (EMR) is an effective treatment for superficial esophageal cancer. However, its feasibility as a salvage treatment for local recurrent or residual tumors after definitive CRT for stage IB, II, and III esophageal cancer remains unclear. Between January 2000 and February 2008, 274 patients with stage IB, II, and III esophageal squamous cell cancer excluding T4 received definitive CRT at the National Cancer Center Hospital, Japan. Of these patients, nine patients with local recurrence after achieving complete response and two patients with residual tumor underwent salvage EMR. The technique of salvage EMR involved a strip biopsy method. We retrospectively reviewed the 11 patients (13 lesions). Characteristics of all 11 patients were as follows: median age of 69 (range: 45-78); male/female: 10/1; baseline clinical stage (Union for International Cancer Control 7th) IB/IIA/IIB/III: 1/3/7/0. The depth of resected tumor was limited to the mucosal layer in seven lesions and submucosal in six lesions. En bloc resection was performed on six lesions (46%). The vertical margin was free of cancer cells in 11 lesions (84.6%). No major complications, such as hemorrhage requiring blood transfusion and perforation, were experienced. At a median follow-up period of 38.9 months (range: 5.3-94 months) after salvage EMR, no recurrence was detected in six patients (54%). Local recurrence was detected in five patients (27%). Of these patients, two had lung metastasis simultaneously, and one was also detected lung metastasis 2 months after the detection of local recurrence. The 5-year survival rate after salvage EMR was 41.6%. Salvage EMR is a feasible treatment option for local recurrent or residual lesions after definitive chemotherapy and/or radiotherapy for stage IB, II, and III esophageal squamous cell cancer.

Abstract
Surrogate biomarkers in the circulation for the enhanced permeation and retention (EPR) effect in different tumor and organ microenvironment shall aid in selecting patients who are likely to accumulate higher amount of nanotherapeutics to tumors and thus show better response to the therapeutics. In this study, 4T1 and 3LL murine cancer cell lines, known to have similar sensitivity to pegylated liposomal doxorubicin (PLD) in vitro, were shown to accumulate significantly different quantities of PLD in vivo. PLD accumulation correlated with tumor-specific differences in therapeutic efficacy and vascular permeability, which was modulated by the extent of coverage of tumor-associated endothelial cells by basement membrane. Matrix metalloproteinase (MMP)-9 and its endogenous inhibitor, tissue inhibitor of metalloproteinase (TIMP)-1, played a pivotal role in these phenomena. Differences in vascular permeability and PLD accumulation were also organ-specific and significantly correlated with the relative ratio of MMP-9 and TIMP-1 in the systemic circulation of the tumor-bearing mice. Our findings support the further development of MMP-9 and TIMP-1 as paired serum biomarkers for predicting accumulation of PLD to tumor and the application of these biomarkers could be expanded to other types of nanotherapeutics utilizing the EPR effect for the personalization of cancer therapy.

Abstract
Abstract
Background: Taxane-based regimens have been developed and used widely to treat breast cancer. It has therefore become important to identify subgroups of patients in which anthracyclines are indispensable. Pathological response to neoadjuvant chemotherapy (NAC) predicts prognosis in hormone-negative subtypes. We therefore initiated a randomized phase II NAC study to compare a taxane with and without an anthracycline in these breast-cancer subtypes.
Aim: To determine the safety and activity of six cycles of docetaxel and cyclophosphamide (TC6) compared with 5-fluorouracil, epirubicin, and cyclophosphamide followed by docetaxel (FEC-D), and to examine the predictive factors for each regimen.
Methods: Eligibility criteria were operable hormone-receptor-negative breast cancer, age younger than 75 years and ECOG PS0-1. According to HER2 status, patients were randomly assigned to TC (75/600 mg/m2) every 3 weeks X 6 or FEC (500/100/500 mg/m2) every 3 weeks X 3 followed by D (100 mg/m2) every 3 weeks X 3. The primary endpoint was the rate of pathological complete response (pCR; grade 3). Triple-negative (TN) breast cancer was subdivided by cytokeratin 5/6 and epidermal growth factor receptor into basal- and non-basal subtypes. Secondary endpoints were safety, breast-conserving surgery, disease-free survival, overall survival, and predictive factors: Ki-67, p53, aldehyde dehydrogenase (ALDH) 1 and topoisomerase 2A by both immunohistochemistry and fluorescence in situ hybridization for each regimen.
Results: Ninety-seven of 103 patients were analyzed successfully (50 for FEC-D and 47 for TC6). Significantly more severe adverse events (grade 2) were observed in FEC-D-treated patients (poor appetite, nausea and vomiting: p = 0.001; febrile neutropenia: p = 0.016). The pCR rate tended to be higher in FEC-D-treated patients compared with TC6-treated patients (pCR: 36.0 vs. 25.5%, n.s.). FEC-D treatment was significantly more effective than TC6 in basal-type (p = 0.033) but not in non-basal and HER2 subtypes. ALDH1 was associated with resistance to both regimens (FEC-D: p = 0.047, TC6: p = 0.085)
Conclusions: TC6 was safer, but not more effective than FEC-D. TC6 was significantly less active than FEC-D in basal subtype, and equivalent to FEC-D in HER2 and non-basal subtypes. Concurrent use of trastuzumab with TC could thus represent a reasonable option for NAC in HER2-subtype patients. ALDH1 could provide a marker for novel strategies such as stem cell-based therapies for breast cancer. Analyses on pathological factors in surgical specimens after NAC will be presented at the meeting.

Abstract
Abstract
In previous decades, numerous attempts have been made to develop therapeutic peptide vaccines for cancer. However, the HLA (Human Leukocyte Antigen) types are limited because most peptide vaccines are specific to the major HLA types of the area. Peptide vaccines specific for Caucasians thus may not be specific to Japanese. Moreover, they are not designed to stimulate both helper and killer T cells. We are trying to make a peptide vaccine specific to the MHC of Japanese patients that stimulates both helper and killer T cells. We selected a new-HER2 peptide including a B-cell epitope which has anti-tumor effects in a mouse system. The B-cell epitope was determined for a H401 monoclonal antibody (mAb) specific for HER2. As for epitope mapping of the chimera mAb CH401, enzyme-linked immunosorbent assay was employed with 20mer MAPs carrying a partial HER2 sequence. The CH401 epitope was determined as N:163-182, and the CH401MAP including the epitope induced anti-tumor effects in HER2-overexpressing tumor cells in a mouse system. We predicted the peptide MHC affinity and examined the in vitro reaction of PBMCs from Japanese breast cancer patients. The study enrolled 173 female breast cancer patients who underwent surgery between October 2010 and July 2012 at Tokai University Hospital. We used SYFPEITHI, BIMAS and IEDB algorithms to estimate peptide and HLA affinity. Lymphocyte proliferation ability, cell surface marker expression, cytokine (interleukin (IL)-2, IL-4 and interferon (IFN)-g) secretion and specific antibody production were analyzed in vitro. According to the algorithms, 97.1% of patients showed high to intermediate affinity of the CH401 epitope peptide to Japanese major HLA class I. Similarly, 34.5% of patients showed high to moderate affinity to HLA class II. The proliferative ability of patient groups was significantly higher than that of the HD group (HER2 0 group, p<0.05; HER2 1+2+ group, p<0.01; HER2 3+ group, p<0.01). Cell percentages of CD8+ cells were significantly increased after 21 days of CH401MAP stimulation. In the HER2 0 patient group, CD4+CD25+ cell ratio was also increased, while no significant increase was seen in the other groups. Foxp-3 expression was not increased in any groups, suggesting that these cells were not regulatory T cells. Concentrations of IL2 in stimulated supernatant tended to increase in all patient groups. In particular, concentration in the HER2 1+2+ group at 48 h was significantly increased (p<0.001). IL-4 and IFN-g secretion also tended to increase. CH401MAP-specific antibodies were measured for all breast cancer patient groups and HD, showing significant differences. However, within each patients’ group, no significant differences were observed irrespective of CH401MAP stimulation (p<0.001). As a result, reactivity with CH401MAP and breast cancer patient PBMCs activated immunity in the total breast cancer patient group, and the association with HER2 expression level of the primary cancer was poor overall. Collectively, CH401MAP may become a promising peptide vaccine to prevent recurrent breast cancer in Japanese patients.

Abstract
BACKGROUND AND STUDY AIMS Gastrectomy with lymph node dissection is the gold standard curative treatment for clinical submucosal invasive early gastric cancer (cSM EGC), but a relatively small number of operable patients with cSM EGC have undergone endoscopic submucosal dissection (ESD) instead because they refused surgery. The aim of this study was to determine the effectiveness of ESD in these operable patients. METHODS The therapeutic outcomes of ESD were retrospectively assessed for 38 patients with 38 operable cSM EGC lesions who initially refused surgery at the National Cancer Center Hospital, Tokyo, from January 1999 to December 2008. RESULTS The en bloc resection rate was 84.2% (32 lesions) and the complete (R0) resection rate was 63.2% (24 lesions). A total of 33 lesions (86.8%) involved submucosal invasion on pathology. Resection was non-curative in 34 patients (89.5%), 22 of whom (64.7%) underwent subsequent gastrectomy after the need for such surgery was carefully explained to them again. The median follow-up period was 73.2 months (range 3-115 months). Local recurrence was detected in one patient, distant metastasis in two patients, and both local recurrence and distant metastasis were detected in one patient. None of these four patients with recurrence (10.5%) had undergone surgery when their recurrent disease was detected and all of them died from gastric cancer. The 5-year cause-specific survival rate for all patients was 91.8%. CONCLUSION The 5-year cause-specific survival rate for all patients was lower than the previously reported rate of 96.7% for pathologically submucosal invasive EGC patients after gastrectomy; therefore, ESD appears to have been an ineffective treatment for operable patients with cSM EGC.

Abstract
AIM 'Predict, resect and discard' strategies for diminutive and small colonic polyps are considered to be cost effective for treating colorectal cancers. The aim of this study was to determine, retrospectively, the histological features of colonic polyps resected by endoscopic procedures or surgery using an updated database. METHOD We retrospectively analysed the clinicopathological features of colorectal polyps, less than 20 mm in size, which were removed by endoscopy from January 2009 to November 2011 at the National Cancer Center Hospital (NCCH) in Tokyo, Japan. RESULTS Less than 1% of diminutive polyps (≤ 5 mm) were classified as mucosal high-grade neoplasia (Category 4), and no submucosal invasion by carcinoma (Category 5) lesions were noted. However, 3% of small polyps (6-9 mm) were classified as Category 5; of these, 6% were submucosal deep invasive cancers. Morphologically, depressed components were observed more frequently in carcinomas than in adenomas in both small and large polyps (10-20 mm). CONCLUSION In light of the 'predict, resect and discard' strategies for small polyps, we should pay attention to the possible clinical malignancy of small and large polyps. We recommend that these strategies should be applied selectively and that they should be informed by accurate endoscopic evaluations.
