Abstract
The causes of the difference in fatty acid composition between gas chromatography (GC) and near-infrared fiber-optic method (NIR) in bovine fat and their countermeasures were studied using absolute values of refractive index. Using intermuscular fat from 45 crossbreeds, refractive index was measured by using a refractometer, and saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) were measured by NIR and GC. The correlation coefficients between GC and NIR in SFA and MUFA, as well as those between refractive index and GC or NIR (in SFA and MUFA), were all greater than or equal to 0.8 (p < 0.01). In samples with 3% or more difference between GC and NIR in SFA and MUFA, GC and NIR values were often located in opposite directions to the regression lines with regard to refractive index. GC reanalysis on these samples slightly increased the correlation coefficient between GC and refractive index and reduced the difference between GC and NIR by 1%-2%. Results indicate that measurement errors in GC and NIR are related to their more than 3% difference, and GC reanalysis based on refractive index may improve its accuracy.

Abstract
OBJECTIVE Partially hydrolyzed guar gum (PHGG), a water-soluble dietary fiber produced by the controlled partial enzymatic hydrolysis of guar gum beans, has various physiological roles. PHGG is expected to influence the immune function and prevent infections. The objective of this study was to examine the effect of continuous ingestion of PHGG for 12 weeks on the development of cold-like symptoms. PATIENTS AND METHODS A placebo-controlled, double blind, randomized, parallel-group comparative study was conducted. 96 healthy Japanese adults received 5.2 g PHGG or placebo daily for 12 weeks. Cold-like symptoms were assessed based on patient diary, and the levels of short-chain fatty acids (SCFAs) in stool and blood immune markers at baseline and at weeks 6 and 12. RESULTS The cumulative number of "no symptoms" days for all symptoms was significantly larger in the PHGG than in the placebo group. The result of the analysis by severity of cold-like symptoms also showed significant differences, with the PHGG group having a lower severity of cold-like symptoms. Propionic acid at weeks 6 and 12 and n-butyric acid and total SCFAs at week 12 were significantly higher in the PHGG than in the placebo group. The Interferon-γ level was significantly lower at week 6 in the PHGG than in the placebo group. CONCLUSIONS PHGG intake may affect immune function and suppress cold-like symptoms through the production of SCFAs in healthy adults.

Abstract
A beam optics study using the ITER-relevant high intense negative ion beams, such as 1 MeV, 200 A/m2, has been performed experimentally and analytically using a multi-aperture and five-stage accelerator. Initially, multi-beamlets generated from this accelerator were deflected in various directions due to the magnetic field and space charge repulsion between beams and showed various divergences. These had limited the pulse length and the beam energy. Compensation methods of the beamlet deflections have worked effectively and contributed to achieving the ITER requirement, the divergence angle of <7 mrad, and the deflection angle of <1 mrad for 1 MeV beam. The beam pulse has been gradually extended from 1 to 100 s and is now going to a longer pulse based on these results. One of the remaining issues is to understand and suppress peripheral components of the beam, namely, the halo, and to reduce the local heat loads observed around the aperture edge. This halo component has been successfully distinguished from the beam core by using a newly developed beam emittance measurement system for high intense beams. By combining this measured beam emittance and the beam simulation, it was clarified for the first time that the halo components are generated in an area of 1 mm width from the aperture edge.

Abstract
The differential cross sections of the Σ^{-}p→Λn reaction were measured accurately for the Σ^{-} momentum (p_{Σ}) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental Facility. Precise angular information about the Σ^{-}p→Λn reaction was obtained for the first time by detecting approximately 100 reaction events at each angular step of Δcosθ=0.1. The obtained differential cross sections show a slightly forward-peaking structure in the measured momentum regions. The cross sections integrated for -0.7≤cosθ≤1.0 were obtained as 22.5±0.68 [statistical error(stat.)] ±0.65 [systematic error(syst.)] mb and 15.8±0.83(stat)±0.52(syst) mb for 470<p_{Σ}(MeV/c)<550 and 550<p_{Σ}(MeV/c)<650, respectively. These results show a drastic improvement compared with past measurements of the hyperon-proton scattering experiments. They will play essential roles in updating the theoretical models of the baryon-baryon interactions.

Abstract
A new hyperon-proton scattering experiment, dubbed J-PARC E40, was performed to measure differential cross sections of the Σ+p, Σ−p elastic scatterings and the Σ−p → Λn scattering by identifying a lot of Σ particles in the momentum ranging from 0.4 to 0.8 GeV/c produced by the π±p → K+Σ± reactions. We successfully measured the differential cross sections of these three channels with a drastically improved accuracy with a fine angular step. These new data will become important experimental constraints to improve the theories of the two-body baryon-baryon interactions. Following this success, we proposed a new experiment to measure the differential cross sections and spin observables by using a highly polarized Λ beam for providing quantitative information on the ΛN interaction. The results of three Σp channels and future prospects of the Λp scattering experiment are described.

Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the Ξ^{-}-^{14}N system a value of 1.27±0.21 MeV was deduced. The energy level of Ξ^{-} is likely a nuclear 1p state which indicates a weak ΞN-ΛΛ coupling.

Abstract
In the three-dimensional (3D) Heisenberg model, topological point defects known as spin hedgehogs behave as emergent magnetic monopoles, i.e., quantized sources and sinks of gauge fields that couple strongly to conduction electrons, and cause unconventional transport responses such as the gigantic Hall effect. We observe a dramatic change in the Hall effect upon the transformation of a spin hedgehog crystal in a chiral magnet MnGe through combined measurements of magnetotransport and small-angle neutron scattering (SANS). At low temperatures, well-defined SANS peaks and a negative Hall signal are each consistent with expectations for a static hedgehog lattice. In contrast, a positive Hall signal takes over when the hedgehog lattice fluctuates at higher temperatures, with a diffuse SANS signal observed upon decomposition of the hedgehog lattice. Our approach provides a simple way to both distinguish and disentangle the roles of static and dynamic emergent monopoles on the augmented Hall motion of conduction electrons.

Abstract
Abstract
Backgrounds
In Japan, some parents with an infant have limited network with others and are feeling anxious and less confident about their child rearing. Many measures for promoting a child-rearing family friendly community are implemented to promote families' healthy development in communities. However, a situation surrounding child-rearing in a community is diverse. The aim of this study is to examine possible indices to monitor and evaluate child-rearing family friendly community.
Methods
This was a cross sectional study with using two kinds of data in one city in Japan. The first one was public data providing information about physical environment related to child-rearing of each community. The second data was on questionnaire answered by a parent of infants from 3 months to 48 months through 2013 to 2019. We merged two kinds of data and examined the association between environment and parents' willingness to raise up children in their community (4 scales) by mixed effect regression model stratified by age of months (under 1 year, 1- and 2-years and 3-years).
Results
Targets of analysis included 2,952 parents of infant under 1 year, 2,342 of 1- and 2-years and 1,977 of 3-year. For parents of infant of 1- and 2-years and 3-years, the closer a child-rearing support center was, the bigger the willingness to raise up a child in their community (β[95%CI]:-0.007[-0.014-/-0.0004], -0.007[-0.012/-0.002, respectively). Also, for parents of 1- and 2-years infant, the closer the park was, the bigger the willingness (-0.014[-0.028/-0.0008]). On the other hand, for parents of infant under 1 year, environment was not statistically significant on their willingness.
Conclusions
It was indicated that user's easiness to visit a consulting space or playing place such as a child-rearing support center or a park become one of indicators for evaluating child-rearing family friendly community in Japan.
Key messages
Child-rearing family friendly environment in a community should be evaluated from the user’s aspect. Further studies including evaluation quality of places or services are needed.

Abstract
To realize stable negative ion beams for 100 s required in the neutral beam injector of JT-60SA, a physical model to control cesium (Cs) distribution inside the negative ion source has been developed in order to maintain the stable negative ion production at the plasma grid (PG) surface with Cs. In this work, to quantitatively evaluate Cs coverage on the PG, a three-dimensional Cs transportation code was introduced to consider the spatial Cs distribution in the source. The spatial temperature distribution of the chamber wall was also introduced in this model. As a result, the reasonable variation of the Cs coverage for 100 s was obtained, compared to that in the initial model. Based on the modified model, the operational temperature of the chamber wall was proposed to be less than 60 °C to suppress the desorption of Cs in the chamber wall and to sustain the stable negative ion production. In addition, it was also suggested that a slightly higher wall temperature before the operation leads to a decrease in the amount of Cs stored at the chamber wall, resulting in suppression of Cs consumption in the ion source.

Abstract
Long pulse acceleration of hydrogen negative ion beams with the power density over 70 MW/m2 and the pulse length over 100 s has been demonstrated for the first time by using a multi-aperture 3-stage accelerator. Such long pulse acceleration was achieved by integrating the design of beam optics and voltage holding capability to meet the requirements of JT-60SA. By using the newly designed accelerator for JT-60SA, voltage holding at 500 kV with beam acceleration was stably sustained even after 5 g of cesium was seeded, and heat load on each acceleration grid was reduced below the allowable level for long pulse, less than 5% of total acceleration power. As a result, 500 keV, 154 A/m2 for 118 s beam acceleration was achieved, which satisfies the requirement of the negative ion source for JT-60SA. This pulse length of such high-power density beams is longest in the world. In addition, the result contributes to the long pulse acceleration of multi-stage electrostatic accelerators, such as 1 MeV negative ion accelerator for ITER.

Abstract
Abstract
Background
Presence of intimate family is considered as one of the related factors of health behaviors. The study aim was to clarify the relationship between the presence of significant others and having a colorectal cancer screening.
Methods
This study used data of baseline survey of intervention study regarding breast cancer screening at worksites. A total of 6827 workers, aged 40 and over of the retail company, were required to fill out a self-administrated questionnaire related to cancer screening. the intimate family was defined as a person’s spouse or partner and children. Logistic regression analyses were performed to estimate odds ratios [ORs] and 95% confidence intervals [CIs] of undergoing an annual screening for colorectal cancer by the presence of spouse or partner adjusting for age. The same analysis was performed regarding the presence of children.
Results
Response rates were 70% in men and 71% in women. After excluding participants with a past history of cancer and lack of information about colorectal cancer screening or the presence of significant others, 4203 remained for the analyses. A total of 1777 participants reported that they had undergone screening for colorectal cancer within a year (42% in men and 42% in women). Screening rates of participants with/without a spouse were 45% and 30% in men, 44% and 38% in women. Screening rates of participants with/without children were 45% and 33% in men, 43% and 38% in women. ORs of undergoing annual colorectal cancer screening by the presence of spouse were 1.8 (1.3-2.5) in men and 1.3 (1.1-1.5) in women. ORs by the presence of children were 1.6 (1.2-2.1) in men and 1.1 (0.9-1.3) in women.
Conclusions
This study indicated that health behavior in cancer screening could be affected by having a spouse in both men and women. The presence of children positively related in men. Male workers with children might be under some pressure to keep their health, from a sense of responsibility of main income earner.
Key messages
Health behavior in cancer screening could be affected by having a spouse. Health behavior in cancer screening could be affected by having a child only in men.

Abstract
Abstract
Background
Vascular response after drug-eluting stent (DES) implantation depends not only on stent design but also on vulnerability of target coronary lesions. In this study, non-obstructive coronary angioscopy (CAS) revealed vascular response after two types of biodegradable polymer (BP) DES implantation into patients with acute coronary syndrome (ACS) or stable angina pectoris (SAP).
Methods
Eighteen Nobori BP biolimus-eluting stents (BP-BES) were successfully implanted into 15 patients (9 ACS and 9 SAP lesions). Twenty-three Ultimaster BP sirolimus-eluting stents (BP-SES) were implanted into 16 patients (6 ACS and 17 SAP lesions). At one year after stenting, CAS semi-quantified degree of neointimal stent coverage (NSC) into 4 grades (0, no coverage; 1, thin coverage; 2, thick coverage; 3, embedded in thick neointima and invisible). When NSC through a stent was composed of plural grades, CAS determined dominant, maximum and minimum NSC grades. Heterogeneity index was defined as subtraction of minimum from maximum grade. CAS also semi-quantified degree of yellow plaques (YP) into 3 grades (0, light; 1, dense; 2, glittering yellow). CAS detected presence of in-stent mural thrombi (ISMT).
Results
At one year after BP-BES implantation: 1) There was no significant difference with regards to dominant NSC between ACS and SAP lesions (1.00±0.50 vs. 0.89±0.60); 2) Heterogeneity index was greater in ACS than in SAP (1.22±0.44 vs. 0.67±0.50, P=0.02); 3) YP grade was greater in ACS than in SAP (1.89±0.33 vs. 1.00±1.00, P=0.02); and 4) We found one ISMT in ACS lesions and two ISMT in SAP lesions. At one year after BP-SES implantation: 1) There was neither significant difference between ACS and SAP lesions with regards to dominant NSC (1.67±1.21 vs. 1.53±1.01), with regards to heterogeneity index (0.50±0.55 vs. 0.35±0.49), nor with regards to YP grade (1.33±1.51 vs. 0.88±0.99); and 2) We found ISMT neither in ACS nor in SAP lesions.
Conclusions
For BP-SES implantation, vascular response at ACS lesions was similar to SAP lesions. Even one year after BP-BES implantation, however, plaque vulnerability appeared to remain in ACS lesions.

Abstract
Abstract
[Background] JBCRG-16 (NeoLath) study is a five-arm study to evaluate the efficacy and safety of lapatinib and trastuzumab (6 weeks) followed by lapatinib and trastuzumab plus weekly paclitaxel (12 weeks) with/without prolongation of anti-HER2 therapy prior to chemotherapy (18 vs. 6 weeks), and with/without endocrine therapy in patients with HER2+ and/or estrogen receptor (ER)+ disease. The primary endpoint was pathological complete response (pCR) rate and pCR rate was 47.9% (Masuda N, et al. Breast Cancer, 2018). It is recently reported that microRNAs (miRNAs) are stably present in serum and potentially useful in the diagnosis and evaluation of treatment of cancer. We performed exploratory analysis of detecting pCR by comprehensive analysis of serum miRNAs.
[Materials and Methods] Serum samples were obtained from study participants who received neoadjuvant systemic therapy with trastuzumab, lapatinib and paclitaxel. Before profiling of miRNAs, the overall serum samples were randomly devided in two sets, namely the training set and the testing set with pCR or non-pCR. Pathological complete response (pCR) was defined as the absence of residual invasive cancer of the resected breast specimen and all sampled regional lymph nodes. Total RNA was extracted from a 300 ul serum sample using 3D-Gene® RNA extraction reagent from a liquid sample kit. A comprehensive quantitative expression analysis of miRNA was performed using the by DNA chip 3D-Gene®, which was designed to detect 2565 miRNA sequences registered in miRBase release 21 (http://www.mirbase.org/). The expression level of miRNAs were normalized by internal control (miR-2861, miR-149-3p and miR-4463). Clinicopathological data was retrieved from trial data.
[Results] A total of 112 samples were obtained. Seventy were used in the training set and others were used in the testing set. Median age was 54 years (range 26-70). Sixty-five (58%) patients were pre-menopausal. ER was positive in 59 patients (52.7%). Fourteen (12.5%) were T1c, 78 (69.6%) were T2 and 20 (17.9%) were T3. Fifty-seven (50.9%) patients were node-positive. Fifty-nine (52.7%) patients achieved pCR. The formula with the combination of three miRNAs (miR-A, miR-B, miR-C) was found to be able to predict pCR. This set had a sensitivity of 62.5%, specificity of 86.7% and accuracy of 71.8% in the testing cohort. Area under curve of receiver operationg characteristic curve was 0.753.
[Conclusion] The combination of three miRNAs has potential to predict pCR in patients who received neoadjuvant combination therapy of trastuzumab, lapatinib and paclitaxel in HER2-positive primary breast cancer. The further analysis of changing expression of miRNAs during neoadjuvant therapy is underway and further results will be presented in the symposium.

Abstract
The cross sections of the ^{7}Be(n,α)^{4}He reaction for p-wave neutrons were experimentally determined at E_{c.m.}=0.20-0.81 MeV slightly above the big bang nucleosynthesis (BBN) energy window for the first time on the basis of the detailed balance principle by measuring the time-reverse reaction. The obtained cross sections are much larger than the cross sections for s-wave neutrons inferred from the recent measurement at the n_TOF facility in CERN, but significantly smaller than the theoretical estimation widely used in the BBN calculations. The present results suggest the ^{7}Be(n,α)^{4}He reaction rate is not large enough to solve the cosmological lithium problem, and this conclusion agrees with the recent result from the direct measurement of the s-wave cross sections using a low-energy neutron beam and the evaluated nuclear data library ENDF/B-VII.1.

Abstract
In this study, nanoscale hydration dynamics of DNA-lipid blend dry films are investigated via small angle X-ray diffraction. Compared to the hydration of lipid films, fragmented short DNA strands and counterions in stacked lipid layers dramatically accelerate both the relaxation of the lamellar distance to a metastable interval and the subsequent peeling-off process of lipid bilayers. Moreover, genome-sized long DNA and counterions accelerate the relaxation process, but suppress the peeling-off process and simultaneously induce a damped-oscillation of the lamellar interval; this is probably due to the viscoelastic properties of the entangled long DNA dissolved in hydrated water between the stacked lipid bilayers. This study's findings can pave the way for producing cell-sized liposomes, which efficiently encapsulate any arbitrary sized DNA through natural swelling.

Abstract
OBJECTIVES Road traffic injuries, particularly pedestrian injuries, are a major health issue among children worldwide. The present study quantitatively analyzed the time trends of child pedestrian injuries in Japan from 1975 to 2013 by age. STUDY DESIGN Time trend analysis of nationally aggregated data. METHODS We analyzed police data on pedestrian injuries requiring medical treatment among children aged 0-15 years occurring between 1975 and 2013. To quantify the time trends of pedestrian injury morbidity rates and to identify change-points in the trends, joinpoint regression analysis was applied by age group. Children were categorized into the age groups of 0-3, 4-6, 7-9, 10-12, and 13-15 years old. RESULTS Preschool children aged 0-6 years old showed continuous declining trends throughout the study period; these declining trends accelerated in the 2000s. School-age children aged 7-15 years old showed minimal changes from the early 1970s to the 1990s; of this age group, children aged 7-12 years old showed slight but significant declining trends in the first half and increasing trends in the latter half of this period. Children aged 7-15 years old showed declining trends in the 2000s. Despite the consistent declining trends among all age groups in the 2000s, the younger age groups showed steeper declines during this period. CONCLUSIONS The declining trends in all age groups in the 2000s may reflect the improved traffic environments in Japan although the environmental approaches are not yet sufficiently adopted yielding modest effects. The continuing contrast between preschool and school-age children may reflect different behaviour changes by age such as more restricted outdoor activities among young children.

Abstract
Compact H(+) ECR ion source using permanent magnets is under development. Switching the hydrogen gas flow in pulse operations can reduce the gas loads to vacuum evacuation systems. A specially designed piezo gas valve chops the gas flow quickly. A 6 GHz ECR ion source equipped with the piezo gas valve is tested. The gas flow was measured by a fast ion gauge and a few ms response time is obtained.

Abstract
In order to realize negative ion sources and accelerators to be applicable to International Thermonuclear Experimental Reactor and JT-60 Super Advanced, a large cesium (Cs)-seeded negative ion source and a multi-aperture and multi-stage electric acceleration have been developed at Japan Atomic Energy Agency (JAEA). Long pulse production and acceleration of the negative ion beams have been independently carried out. The long pulse production of the high current beams has achieved 100 s at the beam current of 15 A by modifying the JT-60 negative ion source. The pulse duration time is increased three times longer than that before the modification. As for the acceleration, a pulse duration time has been also extended two orders of magnitudes from 0.4 s to 60 s. The developments of the negative ion source and acceleration at JAEA are well in progress towards the realization of the negative ion sources and accelerators for fusion applications.

Abstract
To understand the physics of the cesium (Cs) recycling in the large Cs-seeded negative ion sources relevant to ITER and JT-60SA with ion extraction area of 45-60 cm × 110-120 cm, the time evolution of the negative ion profile was precisely measured in JT-60SA where the ion extraction area is longitudinally segmented into 5. The Cs was seeded from the oven at 180 °C to the ion source. After 1 g of Cs input, surface production of the negative ions appeared only in the central segment where a Cs nozzle was located. Up to 2 g of Cs, the negative ion profile was longitudinally expanded over full ion extraction area. The measured time evolution of the negative ion profile has the similar tendency of distribution of the Cs atoms that is calculated. From the results, it is suggested that Cs atom distribution is correlated with the formation of the negative ion profile.

Abstract
Design techniques for the vacuum insulation have been developed in order to realize a reliable voltage holding capability of multi-aperture multi-grid (MAMuG) accelerators for fusion application. In this method, the nested multi-stage configuration of the MAMuG accelerator can be uniquely designed to satisfy the target voltage within given boundary conditions. The evaluation of the voltage holding capabilities of each acceleration stages was based on the previous experimental results about the area effect and the multi-aperture effect. Since the multi-grid effect was found to be the extension of the area effect by the total facing area this time, the total voltage holding capability of the multi-stage can be estimated from that per single stage by assuming the stage with the highest electric field, the total facing area, and the total apertures. By applying these consideration, the analysis on the 3-stage MAMuG accelerator for JT-60SA agreed well with the past gap-scan experiments with an accuracy of less than 10% variation, which demonstrated the high reliability to design MAMuG accelerators and also multi-stage high voltage bushings.

Abstract
Novel compounds based on the lead BRS-3 agonists from our HTS compounds 2a and 2b have been synthesized with the focus on obtaining peripheral BRS-3 agonists. To identify potent anti-obesity compounds without adverse effects on the central nerve system, a labile carboxylic ester with an antedrug functionality was introduced onto the terminal position. Through the extensive synthetic exploration and the pharmacokinetic studies of oral administration in mice, the phenol ester 17c was selected due to the most suitable pharmacological profile. In the evaluation of food intake suppression in B6 mice, 17c showed significant in vivo efficacy and no clear adverse effect on heart rate and blood pressure change in dog iv infusion. Our study paved the way for development of anti-diabetes and obesity drugs with a safer profile.

Abstract
Abstract
Purpose
The value of postmastectomy radiation (PMRT) with adjuvant chemotherapy has been established, but the role of PMRT after neoadjuvant chemotherapy remains unclear.
The aim of this study was to evaluate the efficacy of radiation in patients treated with neoadjuvant chemotherapy and mastectomy, and to determine which subsets of patients benefit from PMRT.
Patients and Methods
From 2003 to 2008, 94 patients were treated with neoadjuvant chemotherapy and mastectomy. The median number of lymph nodes removed was 20. 90 patients received anthracycline-based (anthracycline alone: 5, anthracycline followed by taxane: 85) chemotherapy and 4 patients received taxane alone. 82.6 percent (19/23) of the patients with HER2 positive cancer received trastuzumab and 91.3 percent (63/69) of the patients with hormone receptor positive cancer received hormone therapy. In this study, pathological complete response (pCR) was defined as absence of invasive tumor in the breast.
We compared the outcomes of 55 patients who received radiation (PMRT group) from 39 patinets who did not receive radiation (non-PMRT group).
The 5 years rate of loco-regional recurrence (LRR) was calculated according to the Kaplan-Meier method, and comparisons between the two groups were made using the log-rank test.
Results
Median follow-up time was 61.8 months. The breast pCR rate was 17.0% (16/94). 14 patients developed LRR as first events (local: 8, regional: 4, local and regional: 2). There were no differences between the two groups with respect to age, use of trastzumab, use of hormone therapy, pathological tumor size, number of dissected axillary nodes, percentage of hormone receptor positive tumors, or HER2 positive tumors.
The 5-years rate of LRR for the PMRT group and the non-PMRT group were 12.8% and 27.0% respectively. (p = 0.144) In the patients with positive lymph nodes after neoadjuvant chemotherapy, the PMRT group had significantly lower LRR risk than the non-PMRT group (5-yaers rate: 11.9% vs 37.5%, p = 0.039). But in the patients with negative lymph node, there were no significant difference between the PMRT group and the non-PMRT group. For hormone receptor positive and HER2 negative subtype, a significantly improved LRR risk found after PMRT (5-yaers rate: 5.9% vs 26.1%, p = 0.048). No significant difference in HER2 positive subtype and triple negative subtype were observed between two groups. In the patients who did not achieve breast pCR, the PMRT group had significantly lower LRR risk than the non-PMRT group (5-yaers rate: 9.0% vs 30.6%, p = 0.037). The 5-years rate of lymphedema was no significant difference between the two groups (p = 0.787).
Conclusion
After neoadjuvant chemotherapy and mastectomy, PMRT was found to benefit local control for the patients with positive lymph nodes, the patients with hormone receptor positive and HER2 negative cancer, and the patients who did not achieve breast pCR.

Abstract
Abstract
(Introduction) ABO blood type has been associated with various malignancies, including pancreatic and stomach cancer. However the correlation between blood type and hormone receptor (ER/PR), HER2/neu, patient outcomes remains largely unexplored in patients with breast cancer.
(Methods)This study involved retrospective chart review of patients diagnosed with primary breast cancer stages I-III at Aichi Cancer Hospital between January 2004 and December 2011. Among 1944 breast cancer patients, the relationships between ABO blood type and clinicopathological findings, outcomes were analyzed. Descriptive statistics and c2 analysis were utilized for data summary and comparisons.
(Results) Of 1944 patients, 723 (37%), 577 (29%), 446 (23%), 198 (11%) were blood type A, O, B, AB respectively. This distribution is similar to that reported previously for general Japanese population. 327 (16.8%) patients were ductal carcinoma in situ and 1617 (83.2%) were invasive cancer, and there were no significant differences in this distribution based on each blood types. Among 1617 invasive breast cancer patients, we did not observe significant associations between blood type and pathological T stage or pathological N stage. However, patients with blood type O had lower rate of Luminal type (68.2%) compared blood type A, B, AB (73.5%, 75.2% and 76.0%, respectively (P = 0.03). The blood type O had higher rate of Tripe Negative type (13.7%) compared blood type A, B, AB (10.6%, 9.9% and 8.4%, respectively (P = 0.04). No other statistically significant differences in baseline characteristics among the four blood type groups were noted. No significant differences were observed in type of treatment (endcrine therapy, chemotherapy and anti-HER2 therapy) in each breast cancer subtypes among four blood type groups. Compared to women with blood type A, there was no significant difference in disease free survival among the for blood type O [hazard ratio (HR) 1.754; 95% confidence interval (CI) 0.735-2.731], blood type B (HR 0.978; 95% CI 0.724-1.542.), blood type AB (HR 1.235; 95% CI 0.694-2.864). For patients with blood type O, this difference did not reach statistical significance, although a trend toward worse prognosis of the patients with blood type O status was seen.
(Conclusion) The blood type O had lower rate of Luminal type and higher rate of Tripe Negative type compared other blood types. No significant differences were observed in disease-free survival according to ABO blood types.

Abstract
We report the development of a new trifluoromethyltriazolobenzoxazepine series of squalene synthase inhibitors. Structure-activity studies and pharmacokinetics optimization on this series led to the identification of compound 23 (DF-461), which exhibited potent squalene synthase inhibitory activity, high hepatic selectivity, excellent rat hepatic cholesterol synthesis inhibitory activity, and plasma lipid lowering efficacy in nonrodent repeated dose studies.
