Abstract
Residents of Chikusei City, aged 40-74 years, underwent systemic and ophthalmological screening, and participants with diabetes were included in this analysis. Dietary intake was assessed using a food frequency questionnaire and calculated as a percentage of the total energy. The presence of diabetic retinopathy (DR) was defined as Early Treatment Diabetic Retinopathy Study levels ≥ 20 in either eye. The association between dietary fatty acid intake and DR has been examined in a cross-sectional study. Among the 647 diabetic participants, 100 had DR. The mean total fat and saturated fatty acid (SFA) intakes were 22.0% and 7.3% of the total energy intake, respectively. After adjusting for potential confounders, the highest quartiles of total fat and SFA intake were positively associated with the presence of DR compared with the lowest quartiles (odds ratios (95% confidence intervals), 2.61 (1.07-6.39), p for trend = 0.025, and 2.40 (1.12-5.17), p for trend = 0.013, respectively). No significant associations were found between DR prevalence and monounsaturated or unsaturated fatty acid intake. These results suggest that a high intake of fat and SFA may affect the development of DR, even in individuals whose total fat intake is generally much lower than that of Westerners.

Abstract
Purpose To determine the associations between fatty acid intakes and the prevalence of age-related macular degeneration (AMD) under a population-based cross-sectional study. Methods Residents of Chikusei City aged ≥40 years underwent systemic and eye screening. AMD was graded according to a modified version of the Age-Related Eye Disease Study classification. Dietary intake was assessed using a food frequency questionnaire and was adjusted for total energy intake. Results Altogether, 10,788 eyes of 5394 participants, 2116 men (mean [standard deviation (SD)] age, 62.4 [9.4] years) and 3278 women (60.6 [9.5] years), were included. The mean daily total fat intakes were 52.8 g and 59.0 g in men and women, respectively. After adjustments for potential confounders, saturated fatty acid (SFA) intake was inversely associated with the prevalence of any AMD in men (for each energy-adjusted 1-SD increase: odds ratio [OR], 0.86; 95% confidence interval [CI], 0.74-1.00). Significant trends were found for decreasing odds ratios of AMD with increasing SFA, monounsaturated fatty acid (MUFA), and polyunsaturated fatty acid (PUFA) intake (P for trend = 0.02, 0.04, and 0.04, respectively). In women, only a significant association was observed between the second quartile of linolenic acid intake and the prevalence of any AMD (OR, 0.78; 95% CI, 0.62-0.99). Conclusions We found an inverse association of SFA intake and a weak inverse association of MUFA and PUFA intakes with the prevalence of any AMD in a Japanese population. Translational Relevance Adequate fatty acid intake may be necessary to prevent or decelerate AMD.

Abstract
Superparamagnetic iron oxide (SPIO)-enhanced MRI at 1.5 T with fat-suppression sequence is useful for the detection of metastases in sentinel nodes localized by CT lymphography in patients with breast cancer. SPIO-enhanced MRI may offer an alternative to sentinel node biopsy and avoid axillary surgery itself for patients with breast cancer who have negative sentinel nodes on SPIO-enhanced MRI.

Abstract
Sterile intra-amniotic inflammation is a clinical condition frequently observed in women with preterm labor and birth, the leading cause of neonatal morbidity and mortality worldwide. Growing evidence suggests that alarmins found in amniotic fluid, such as interleukin (IL)-1α, are central initiators of sterile intra-amniotic inflammation. However, the causal link between elevated intra-amniotic concentrations of IL-1α and preterm birth has yet to be established. Herein, using an animal model of ultrasound-guided intra-amniotic injection of IL-1α, we show that elevated concentrations of IL-1α cause preterm birth and neonatal mortality. Additionally, using immunoblotting techniques and a specific immunoassay, we report that the intra-amniotic administration of IL-1α induces activation of the NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome in the fetal membranes, but not in the decidua, as evidenced by a concomitant increase in the protein levels of NLRP3, active caspase-1, and IL-1β. Lastly, using Nlrp3-/- mice, we demonstrate that the deficiency of this inflammasome sensor molecule reduces the rates of preterm birth and neonatal mortality caused by the intra-amniotic injection of IL-1α. Collectively, these results demonstrate a causal link between elevated IL-1α concentrations in the amniotic cavity and preterm birth as well as adverse neonatal outcomes, a pathological process that is mediated by the NLRP3 inflammasome. These findings shed light on the mechanisms underlying sterile intra-amniotic inflammation and provide further evidence that this clinical condition can potentially be treated by targeting the NLRP3 inflammasome.

Abstract
PURPOSE To determine the relationship of choroidal thickness with the early stages of age-related macular degeneration (AMD) and their disease features in a Japanese population. DESIGN Cross-sectional survey. PARTICIPANTS A total of 1293 Japanese persons 65 to 86 years of age residing in the Saku area who underwent eye screening as part of the Japan Public Health Center-based Prospective Study. METHODS Comprehensive ophthalmic assessment included fundus photography, measurement of intraocular pressure, and determination of refractive status. OCT with enhanced depth imaging mode was performed and subfoveal choroidal thickness was assessed. Multinomial logistic regression models were used to assess the relationships of choroidal thickness with the early stages of AMD, namely early AMD and intermediate AMD, and their disease features, after adjustment for potential confounders. MAIN OUTCOME MEASURES Relationship of choroidal thickness with early AMD, intermediate AMD, and their disease features. RESULTS Of 1293 potential participants, 901 (mean age, 73.2 years) had choroidal thickness data, fundus photographs of sufficient quality, and no concomitant retinal disease (including 5 with late AMD). Mean choroidal thickness was 246.1 μm, 15.1% had early AMD, and 9.0% had intermediate AMD. After adjustment for age, gender, and refractive status, choroidal thickness was associated positively with presence of intermediate AMD (for each 1- standard deviation [SD] μm increase: odds ratio [OR], 1.43; 95% confidence interval [CI], 1.13-1.81), whereas no significant association was found with presence of early AMD. Among intermediate AMD features, choroidal thickness was associated positively with presence of AMD pigmentary abnormalities (associated with at least medium drusen; for each 1-SD μm increase: OR, 2.21; 95% CI, 1.42-3.42), whereas no significant association was found with presence of large drusen alone. In addition, among large drusen subtypes, choroidal thickness was associated positively with presence of pachydrusen (for each 1-SD μm increase: OR, 1.53; 95% CI, 1.10-2.13). Furthermore, exploratory analysis revealed that choroidal thickness was associated positively with presence of non-AMD pigmentary abnormalities (for each 1-SD μm increase: OR, 1.92; 95% CI, 1.31-2.18). CONCLUSIONS Choroidal thickness seems to be associated with the pathology of intermediate AMD and its features in Asians.

Abstract
The ultra-bright femtosecond X-ray pulses provided by X-ray Free Electron Lasers (XFELs) open capabilities for studying the structure and dynamics of a wide variety of biological and inorganic systems beyond what is possible at synchrotron sources. Although the structure and chemistry at the catalytic sites have been studied intensively in both biological and inorganic systems, a full understanding of the atomic-scale chemistry requires new approaches beyond the steady state X-ray crystallography and X-ray spectroscopy at cryogenic temperatures. Following the dynamic changes in the geometric and electronic structure at ambient conditions, while overcoming X-ray damage to the redox active catalytic center, is key for deriving reaction mechanisms. Such studies become possible by using the intense and ultra-short femtosecond X-ray pulses from an XFEL, where sample is probed before it is damaged. We have developed methodology for simultaneously collecting X-ray diffraction data and X-ray emission spectra, using an energy dispersive spectrometer, at ambient conditions, and used this approach to study the room temperature structure and intermediate states of the photosynthetic water oxidizing metallo-protein, photosystem II. Moreover, we have also used this setup to simultaneously collect the X-ray emission spectra from multiple metals to follow the ultrafast dynamics of light-induced charge transfer between multiple metal sites. A Mn-Ti containing system was studied at an XFEL to demonstrate the efficacy and potential of this method.

Abstract
A common challenge for pump-probe studies of structural dynamics at X-ray free-electron lasers (XFELs) is the determination of time zero (T0)-the time an optical pulse (e.g., an optical laser) arrives coincidently with the probe pulse (e.g., a XFEL pulse) at the sample position. In some cases, T0 might be extracted from the structural dynamics of the sample's observed response itself, but generally, an independent robust method is required or would be superior to the inferred determination of T0. In this paper, we present how the structural dynamics in ultrafast melting of bismuth can be exploited for a quickly performed, reliable and accurate determination of T0 with a precision below 20 fs and an overall experimental accuracy of 50 fs to 150 fs (estimated). Our approach is potentially useful and applicable for fixed-target XFEL experiments, such as serial femtosecond crystallography, utilizing an optical pump pulse in the ultraviolet to near infrared spectral range and a pixelated 2D photon detector for recording crystallographic diffraction patterns in transmission geometry. In comparison to many other suitable approaches, our method is fairly independent of the pumping wavelength (UV-IR) as well as of the X-ray energy and offers a favorable signal contrast. The technique is exploitable not only for the determination of temporal characteristics of the experiment at the interaction point but also for investigating important conditions affecting experimental control such as spatial overlap and beam spot sizes.

Abstract
Free-electron lasers providing ultra-short high-brightness pulses of X-ray radiation have great potential for a wide impact on science, and are a critical element for unravelling the structural dynamics of matter. To fully harness this potential, we must accurately know the X-ray properties: intensity, spectrum and temporal profile. Owing to the inherent fluctuations in free-electron lasers, this mandates a full characterization of the properties for each and every pulse. While diagnostics of these properties exist, they are often invasive and many cannot operate at a high-repetition rate. Here, we present a technique for circumventing this limitation. Employing a machine learning strategy, we can accurately predict X-ray properties for every shot using only parameters that are easily recorded at high-repetition rate, by training a model on a small set of fully diagnosed pulses. This opens the door to fully realizing the promise of next-generation high-repetition rate X-ray lasers.

Abstract
Abstract
Background: The aim of this prospective study is to evaluate feasibility of the periareolar injection of contrast agent (Sonazoid (SNZ)) followed by ultrasonography (US) for identification of sentinel lymph node (SLN) in breast cancer patients with clinically negative node.
Patients and Methods: Patients with T1-2N0M0 breast cancer were recruited in this study. They received the periareolar injection of SNZ followed by US to identify contrast-enhanced SLN. Fine needle aspiration biopsy (FNAB) was done for each CE-SLN. Then, they underwent SLN biopsy with the conventional method, blue dye and/or radiotracer (B/R).
Results: In almost all cases, contrast-enhanced lymphatic vessels were clearly visualized US soon after the periareolar injection of SNZ, and SLN, into which lymphatic flow was draining, was easily identified. The identification rate of SLN was 98% (98/100) by SNZ and 100% (100/100) by B/R. The number of SLNs identified by SNZ (mean per patient, 1.52) was significantly (P < 0.001) lower than that of those by B/R (2.22). Twenty-five patients had at least one metastasis in the SLNs identified by SNZ and/or B/R. In these patients, SLNs (n=39) identified by both SNZ and B/R showed a significantly (P < 0.0001) higher positivity (74.4%) for metastases than those (n=19) identified by B/R alone (21.1%).
Conclusion: Identification of SLN by periareolar injection of SNZ followed by US is a technically easy method and the identification rate of SLN was as high as 98%, being comparable to the conventional B/R. SLNs detected by SNZ seem to represent the true SLNs which first receive lymphatic flow from the tumor among the SLNs detected by B/R.

Abstract
Inner-shell ionization of an isolated atom typically leads to Auger decay. In an environment, for example, a liquid or a van der Waals bonded system, this process will be modified, and becomes part of a complex cascade of relaxation steps. Understanding these steps is important, as they determine the production of slow electrons and singly charged radicals, the most abundant products in radiation chemistry. In this communication, we present experimental evidence for a so-far unobserved, but potentially very important step in such relaxation cascades: Multiply charged ionic states after Auger decay may partially be neutralized by electron transfer, simultaneously evoking the creation of a low-energy free electron (electron transfer-mediated decay). This process is effective even after Auger decay into the dicationic ground state. In our experiment, we observe the decay of Ne2+ produced after Ne 1s photoionization in Ne-Kr mixed clusters.

Abstract
The hitherto unexplored two-photon doubly excited states [Ne^{*}(2p^{-1}3s)]_{2} were experimentally identified using the seeded, fully coherent, intense extreme ultraviolet free-electron laser FERMI. These states undergo ultrafast interatomic Coulombic decay (ICD), which predominantly produces singly ionized dimers. In order to obtain the rate of ICD, the resulting yield of Ne_{2}^{+} ions was recorded as a function of delay between the extreme ultraviolet pump and UV probe laser pulses. The extracted lifetimes of the long-lived doubly excited states, 390(-130/+450) fs, and of the short-lived ones, less than 150 fs, are in good agreement with ab initio quantum mechanical calculations.

Abstract
Ne clusters (∼5000 atoms) were resonantly excited (2p→3s) by intense free electron laser (FEL) radiation at FERMI. Such multiply excited clusters can decay nonradiatively via energy exchange between at least two neighboring excited atoms. Benefiting from the precise tunability and narrow bandwidth of seeded FEL radiation, specific sites of the Ne clusters were probed. We found that the relaxation of cluster surface atoms proceeds via a sequence of interatomic or intermolecular Coulombic decay (ICD) processes while ICD of bulk atoms is additionally affected by the surrounding excited medium via inelastic electron scattering. For both cases, cluster excitations relax to atomic states prior to ICD, showing that this kind of ICD is rather slow (picosecond range). Controlling the average number of excitations per cluster via the FEL intensity allows a coarse tuning of the ICD rate.

Abstract
In high-intensity laser light, matter can be ionized by direct multiphoton absorption even at photon energies below the ionization threshold. However on tuning the laser to the lowest resonant transition, the system becomes multiply excited, and more efficient, indirect ionization pathways become operative. These mechanisms are known as interatomic Coulombic decay (ICD), where one of the species de-excites to its ground state, transferring its energy to ionize another excited species. Here we show that on tuning to a higher resonant transition, a previously unknown type of interatomic Coulombic decay, intra-Rydberg ICD occurs. In it, de-excitation of an atom to a close-lying Rydberg state leads to electron emission from another neighbouring Rydberg atom. Moreover, systems multiply excited to higher Rydberg states will decay by a cascade of such processes, producing even more ions. The intra-Rydberg ICD and cascades are expected to be ubiquitous in weakly-bound systems exposed to high-intensity resonant radiation. Interatomic Coulombic decay (ICD) is a relaxation of an atom in a weakly bound environment by the transfer of excess energy to ionize the neighbouring atom. Here the authors observe intra-Rydberg ICD in neon clusters, which is a decay that involves the ionization of Rydberg atoms in the cluster.

Abstract
Workshops are an important part of the IFPA annual meeting as they allow for discussion of specialised topics. At the 2015 IFPA annual meeting there were 12 themed workshops, three of which are summarized in this report. These workshops related to various aspects of placental biology and collectively covered areas of obesity and the placenta, stem cells of the feto-maternal interface, and placental immunobiology and infection.

Abstract
We studied the electronic and nuclear dynamics of I-containing organic molecules induced by intense hard X-ray pulses at the XFEL facility SACLA in Japan. The interaction with the intense XFEL pulse causes absorption of multiple X-ray photons by the iodine atom, which results in the creation of many electronic vacancies (positive charges) via the sequential electronic relaxation in the iodine, followed by intramolecular charge redistribution. In a previous study we investigated the subsequent fragmentation by Coulomb explosion of the simplest I-substituted hydrocarbon, iodomethane (CH3I). We carried out three-dimensional momentum correlation measurements of the atomic ions created via Coulomb explosion of the molecule and found that a classical Coulomb explosion model including charge evolution (CCE-CE model), which accounts for the concerted dynamics of nuclear motion and charge creation/charge redistribution, reproduces well the observed momentum correlation maps of fragment ions emitted after XFEL irradiation. Then we extended the study to 5-iodouracil (C4H3IN2O2, 5-IU), which is a more complex molecule of biological relevance, and confirmed that, in both CH3I and 5-IU, the charge build-up takes about 10 fs, while the charge is redistributed among atoms within only a few fs. We also adopted a self-consistent charge density-functional based tight-binding (SCC-DFTB) method to treat the fragmentations of highly charged 5-IU ions created by XFEL pulses. Our SCC-DFTB modeling reproduces well the experimental and CCE-CE results. We have also investigated the influence of the nuclear dynamics on the charge redistribution (charge transfer) using nonadiabatic quantum-mechanical molecular dynamics (NAQMD) simulation. The time scale of the charge transfer from the iodine atomic site to the uracil ring induced by nuclear motion turned out to be only ∼5 fs, indicating that, besides the molecular Auger decay in which molecular orbitals delocalized over the iodine site and the uracil ring are involved, the nuclear dynamics also play a role for ultrafast charge redistribution. The present study illustrates that the CCE-CE model as well as the SCC-DFTB method can be used for reconstructing the positions of atoms in motion, in combination with the momentum correlation measurement of the atomic ions created via XFEL-induced Coulomb explosion of molecules.

Abstract
BACKGROUND The aim of this study was to evaluate whether MRI at 3 T with superparamagnetic iron oxide (SPIO) enhancement is an accurate and useful method for detecting metastases in sentinel nodes identified by CT-lymphography (CT-LG) in patients with breast cancer. The results were compared with those obtained using CT-LG alone and diagnosing metastasis according to size criteria. METHODS Patients with clinically node-negative breast cancer were included. Sentinel nodes identified by CT-LG were evaluated prospectively using SPIO-enhanced MRI at 3 T. Sentinel node size was measured on CT-LG, and a node larger than 5 mm in short-axis diameter was considered metastatic. Sentinel nodes localized by CT-LG were removed, and imaging results and histopathological findings were compared. RESULTS Sentinel nodes were identified successfully by CT-LG in 69 (99 per cent) of 70 patients. All 19 patients with a finding of metastasis in sentinel nodes at pathology were also shown to have metastases on MRI. Forty-eight of 50 patients with non-metastatic sentinel nodes diagnosed at pathology were classified as having non-metastatic nodes on MRI. On a patient-by-patient basis, the sensitivity, specificity and accuracy of MRI for the diagnosis of sentinel node metastases were 100, 96 and 97 per cent; respective values for CT-LG were 79, 56 and 62 per cent. The specificity and accuracy of MRI were superior to those of CT-LG (P < 0·001 and P = 0·002 respectively). CONCLUSION SPIO-enhanced MRI at 3 T is useful for accurate diagnosis of metastatic sentinel nodes, indicating that sentinel node biopsy may be avoided in patients with breast cancer who have non-metastatic sentinel nodes on imaging.

Abstract
Abstract
BACKGROUND: Sentinel node biopsy (SNB) for the node negative breast cancer is standard treatment as an accurate assessment of axillary lymph node status; however, axillary node dissection is a standard procedure for the node positive breast cancer. Neoadjuvant chemotherapy (NAC) has become the standard of care for patients with locally advanced breast cancer. It is reported that 40% of node positive disease convert to node negative after NAC. It remains controversial whether SLB could be applied to patients who present with node-positive disease before neoadjuvant chemotherapy. In this study, we evaluated the accuracy of SNB following NAC in breast cancer patients presenting with cytology-proven axillary node metastasis before chemotherapy.
METHODS: A multicenter prospective study was performed from September 2011 to April 2013 in 101 breast cancer patients with positive axillary nodes, proven by ultrasound-guided fine-needle aspiration at initial diagnosis (T1-3, N1, M0). After the confirmation of patients as clinically node-negative by preoperative imaging following NAC, all patients underwent breast surgery, with SNB and complete axillary lymph node dissection. The sentinel nodes were examined by hematoxylin-eosin staining, immunohistochemical analysis or one-step nucleic acid amplification assay (OSNA).The false negative rate and detection rate were analyzed.
RESULTS: Among the 101 patients analyzed, all cases presented with invasive ductal carcinoma. with a mean tumor size of 3.4cm. Thirty-six cases were hormone receptor (HR) positive and HER2 negative (Lum), 14 cases were HR positive and HER2 positive (Triple-Positive), 27 cases were positive for HER2 (HER2-enriched), and 24 cases were Triple-Negative. After neoadjuvant chemotherapy, a complete clinical response in the primary tumor was seen in 24.8%(25/101), a partial response in 66.3%(67/101), and no response in 7.9%(8/101). Pathological complete response of primary tumor was 39.6%. The pathological complete nodal response rate was 42.2%. The sentinel lymph node could be identified in 91 of 101 cases (90.1%); 88.9% (32/36) of patients with Lum, 100%(14/14)of those with Triple-Positive, 85.2% (23/27) of those with HER2-enriched, and 91.7% (22/24)% of those with Triple-Negative breast cancer subtype. The false negative rate was 12.7%; 35.7 (5/14) for Lum, 0% (0/8) for Triple-Positive, 5.0% (1/20) for HER2-enriched, and 7.7% (1/13) for Triple-Negative subtype (P = 0.03).
CONCLUSION: SNB following NAC in patients with node-positive breast cancer was found to be technically feasible, but is not recommended for the Lum subtype. However, it might be safely considered in selected patients, those with Triple-Positive, HER2-enrich and Triple-Negative subtype breast cancers.

Abstract
When exposed to ultraintense x-radiation sources such as free electron lasers (FELs) the innermost electronic shell can efficiently be emptied, creating a transient hollow atom or molecule. Understanding the femtosecond dynamics of such systems is fundamental to achieving atomic resolution in flash diffraction imaging of noncrystallized complex biological samples. We demonstrate the capacity of a correlation method called "partial covariance mapping" to probe the electron dynamics of neon atoms exposed to intense 8 fs pulses of 1062 eV photons. A complete picture of ionization processes competing in hollow atom formation and decay is visualized with unprecedented ease and the map reveals hitherto unobserved nonlinear sequences of photoionization and Auger events. The technique is particularly well suited to the high counting rate inherent in FEL experiments.

Abstract
We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x-ray free-electron laser facility, SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xe(n+) with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n≥24) are produced via five-photon absorption, evidencing the occurrence of multiphoton absorption involving deep inner shells. A newly developed theoretical model, which shows good agreement with the experiment, elucidates the complex pathways of sequential electronic decay cascades accessible in heavy atoms. The present study of heavy-atom ionization dynamics in high-intensity hard-x-ray pulses makes a step forward towards molecular structure determination with x-ray free-electron lasers.

Abstract
Abstract
Background
Superparamagnetic iron oxide (SPIO)-enhanced MR imaging has been reported to be promising for the detection of metastases in sentinel nodes localized by CT lymphography in patients with breast cancer (Motomura, Ann Surg Oncol 2011). The current SPIO technique involves imaging before and after contrast administration. This study evaluated the accuracy of SPIO-enhanced MR imaging alone without unenhanced imaging.
Methods: This study included 120 patients with breast cancer demonstrating clinically negative nodes. Sentinel nodes were identified by CT lymphography, and MR imaging of the axilla before and 18–24 hr after interstitial administration of SPIO was performed. A node was considered non-metastatic if it showed a homogenous low signal intensity and metastatic if there was an absence of low signal intensity either in the entire node or in a focal area on SPIO-enhanced MR imaging. The diagnostic accuracy of the SPIO-enhanced imaging alone was compared with that of combined unenhanced and SPIO-enhanced imaging.
Results: The mean number of sentinel nodes identified by CT lymphography was 1.2 (range 1–3). Pathologic evaluation demonstrated that 28 (23.3%) of 120 patients showed metastasis to at least one node. One false negative result was added when the evaluation was based solely on SPIO-enhanced MR imaging. Consequently, the sensitivity decreased from 84.0% to 80.0% and the accuracy decreased from 89.2% to 88.3%, respectively, in the SPIO-enhanced MR imaging alone. However, the differences in sensitivity and accuracy between SPIO-enhanced MR imaging alone and the combined unenhanced and SPIO-enhanced imaging were not significant (McNemar's test; p=1.0). The specificity of enhanced imaging alone and that of combined unenhanced and SPIO-enhanced imaging were both 90.5%.
Conclusions: A single MR imaging examination performed after SPIO administration can be used for accurate diagnosis of sentinel node metastases, and thus reduce the time and cost of imaging.

Abstract
Second-order autocorrelation spectra of XUV free-electron laser pulses from the Spring-8 Compact SASE Source (SCSS) have been recorded by time and momentum resolved detection of two-photon single ionization of He at 20.45 eV using a split-mirror delay-stage in combination with high-resolution recoil-ion momentum spectroscopy (COLTRIMS). From the autocorrelation trace we extract a coherence time of 8 ± 2 fs and a mean pulse duration of 28 ± 5 fs, much shorter than estimations based on electron bunch-length measurements. Simulations within the partial coherence model [Opt. Lett. 35, 3441 (2010)] are in agreement with experiment if a pulse-front tilt across the FEL beam diameter is taken into account that leads to a temporal shift of about 6 fs between both pulse replicas.

Abstract
Glioblastomas (GBMs) are the most common and aggressive type of brain tumor. GBMs usually show hyperactivation of the PI3K-Akt pathway, a pro-tumorigenic signaling cascade that contributes to pathogenesis. Girdin, an actin-binding protein identified as a novel substrate of Akt, regulates the sprouting of axons and the migration of neural progenitor cells during early postnatal-stage neurogenesis in the hippocampus. Here, we show that Girdin is highly expressed in human glioblastoma (GBM). Stable Girdin knockdown in isolated GBM stem cells resulted in decreased expression of stem cell markers, including CD133, induced multilineage neural differentiation, and inhibited in vitro cell motility, ex vivo invasion, sphere-forming capacity and in vivo tumor formation. Furthermore, exogenous expression of the Akt-binding domain of Girdin, which competitively inhibits its Akt-mediated phosphorylation, diminished the expression of stem cell markers, SOX2 and nestin, and migration on the brain slice and induced the expression of neural differentiation markers glial fibrillary acidic protein/βIII Tubulin. Our results reveal that Girdin is required for GBM-initiating stem cells to sustain the stemness and invasive properties.

Abstract
15 Background: Sentinel lymph node biopsy (SLNB) is a widely accepted staging method for patients with early breast cancer. But SLNB following neoadjuvant chemotherapy (NAC) is also controversial because of insufficient evidence to recommend as a standard procedure. The aim of our study was to demonstrate the feasibility of SNLB following NAC. Methods: The clinical study of SLNB for clinically node-negative breast cancer patient was conducted as a large cohort study to confirm the identification rate and safety of this procedure. It was investigated by The Japanese Breast Cancer Society and was accomplished between the years March 2008 and October 2009. In this study 11,228 cases are registered before SLNB from 64 institutions. Of the 11,228 eligible cases, analysis was conducted among 489 cases that were introduced neoadjuvant chemotherapy. Results: SLNB was performed in 110 cases before NAC, 379 cases after NAC. The sentinel node identification rate before NAC was 106/110 cases (96.4%), after NAC was 373/379 cases (98.4%). Intraoperative frozen section analysis was performed in 280 cases, 71 cases were positive. The remaining 219 patients displayed no metastasis in the intraoperative examination, and 6 of these 219 (2.7%) were positive in the final pathological analysis. Conclusions: The identification rate of SLNB following NAC is not inferior to the result of major clinical studies previously reported in the world. There is insufficient evidence to recommend this as a standard procedure. Further research with subgroup analysis is necessary to identify whether SLNB following NAC is feasible or not (planned study). The primary end point for Group A is local relapse rate, Group B is not only the accuracy and false negative rate also the utility of One-step Nucleic Acid Amplification (OSNA).

Abstract
14 Background: Several nomograms have been described as predictors of non-sentinel axially lymph node (non-SN) metastases in breast cancer with positive sentinel nodes (SN). However, all these predicting models were based on data from western countries. The purpose of this study was to examine predictive factors of non-SN status among SN metastatic patients, in order to develop a nomogram based on Japanese large data set. Methods: This research was analyzed by using a clinical database of 11,228 Japanese breast cancer patients who registerd to cohort study as SN biopsy between March 2008 and Octover 2009 in Japan. We reviewed data retrospectively to extract patients with SN metastases who underwent complementary axillary lymph node dissection. In this cohort, we examined predictive factors of non-SN metastases. All clinical and pathologic features were analyzed to predict the non-SN status, by using univariate and multivariate logistic regression model. A receiver operating characteristic curve was constructed and the area under the curve (AUC) was calculated. Results: Among the database, SN metastases were found in 1,029 patients, and 345 (33.5%) were non-SN positive. Univariate analysis showed a significant association between non-SN involvement and primary tumor size (p<0.001), histologic grade (p=0.011), lymphatic invasion (p<0.001), venous invasion (p=0.005) and the number of involved SNs among all identified SNs (p<0.001). Tumor size (p<0.001), lymphatic invasion (p<0.001), and the size of SN metastasis (p<0.001) were associated with non-SN metastasis in multivariate analysis. Based on the multivariate analysis, we developed a scoring system to predict the likelihood of non-SN metastases in breast cancer patients with SN involvement. The discriminatory ability of our nomogram, as measured by the AUC, was 0.752. Conclusions: In patients with invasive breast cancer and a positive SN, primary tumor size, lymphatic invasion, and the size of SN metastases among all identified SNs were independently predictive of non-SN involvement, and used for a nomogram. Validation study will be performed in the future investigation.

Abstract
BACKGROUND Hereditary neuralgic amyotrophy (HNA), also known as hereditary brachial plexus neuropathy, has phenotypic and genetic heterogeneity. Mutations in the septin 9 (SEPT9) gene were recently identified in some HNA patients. The phenotypic spectrum of HNA caused by SEPT9 mutations is not well known. OBJECTIVE To characterise the phenotype of a large family of HNA patients with the SEPT9 R88W mutation. METHODS We report clinical, electrophysiological, neuroimaging and genetic findings of six HNA patients from a Japanese family. RESULTS All 17 neuropathic episodes identified were selectively and asymmetrically distributed in the upper-limb nerves. Severe pain was an initial symptom in 16 episodes (94%). Motor weakness occurred in 15 (88%) and sensory signs in 10 (59%). A minor dysmorphism, hypotelorism, was seen in all. Nerve conduction studies revealed focal demyelination as well as prominent axonal degeneration changes. Needle electromyography revealed chronic neurogenic patterns only in the upper limbs. An MRI study showed a gadolinium-enhanced brachial plexus. The missense mutation c.262C>T; p.R88W was found in exon 2 of SEPT9 in all patients. CONCLUSIONS The SEPT9 R88W mutation in this family causes selective involvement of the brachial plexus and upper-limb nerves. Wider and more universal recognition of clinical hallmarks and genetic counselling are of diagnostic importance for HNA caused by the SEPT9 mutation.

Abstract
Abstract
Background: Ultrasonography, magnetic resonance (MR) imaging, and computed tomography (CT) may detect nodal metastases in patients with breast cancer, but there is not sufficient accuracy with the conventional methods. Recently, superparamagnetic nanoparticles-enhanced MR imaging has been reported to be a promising improvement for diagnostic imaging of lymph node metastases from various tumors. Moreover, sentinel nodes have been reported to be well-identified using CT lymphography in patients with breast cancer. This study evaluated MR imaging with superparamagnetic iron oxide (SPIO) enhancement for the detection of metastases in sentinel nodes localized by CT lymphography in patients with breast cancer, with histopathologic findings as the reference standard.Methods: This study included 102 patients with breast cancer with clinically negative nodes. Each contrast agent was injected intradermally into the skin overlying the breast tumor and in the subareolar region. Sentinel nodes were identified by CT lymphography, and SPIO-enhanced MR imaging of the axilla was performed to detect metastases in the sentinel nodes. A node was considered non-metastatic if it showed a homogenous low signal intensity and metastatic if the entire node or a focal area did not show a low signal intensity on MR imaging. Sentinel node biopsy was performed using a combination of dye and radiocolloid. Imaging results were correlated with histopathologic findings.Results: The mean number of sentinel nodes identified by CT lymphography was 1.1 (range 1–3). Twenty-one of 25 patients with positive sentinel nodes definitively diagnosed by pathology demonstrated metastases on SPIO-enhanced MR imaging. Seventy of 77 patients with negative sentinel nodes definitively diagnosed by pathology were non-metastatic on imaging studies. The sensitivity, specificity, and overall accuracy of MR imaging for the diagnosis of sentinel node metastases were 84%, 91%, and 89%, respectively. In four of 10 patients with micrometastases, the metastases were not detected, but all 15 patients with macrometastases were successfully demonstrated. There were no adverse events associated with either CT or MR imaging.Conclusions: SPIO-enhanced MR imaging is a useful method of detecting metastases in sentinel nodes localized by CT lymphography in patients with breast cancer. Patients with clinically negative nodes may be spared sentinel node biopsy when the sentinel node is diagnosed as disease-free using SPIO-enhanced MR imaging.

Abstract
Abstract #2158
Background: Thermal ablation therapy using lasers, ultrasound and microwaves is being investigated as a less invasive alternative to surgery for breast cancer. This study examined the efficacy of magnetic nanoparticles, which produce heat when exposed to an alternating magnetic field, for the destruction of breast cancer in mice.
 Material and Methods: Tumors were induced on both sides of the back of BALB/C mice by subcutaneous injection of MDA-MB-231 breast cancer cells. Magnetic nanoparticles were injected in and around one of the tumors in a mouse, while saline were injected in another tumor (control). Mice were exposed to an alternating magnetic field for 40 min. The temperature of the tumor injected with nanoparticles reached 45°C and was maintained at that temperature by adjusting the magnetic field intensity. Histopathological response was evaluated one to two months after thermal ablation therapy.
 Results: In 8 (67%) of 12 mice, complete tumor regression was observed in tumors treated with nanoparticle injection, while there was no regression in control tumors in any of the mice. There was no irreversible damage seen in normal tissue surrounding the nanoparticle injected tumors.
 Discussion: Since this procedure can destroy cancer cells specifically without injuring normal tissue, it may be applicable to the treatment of human breast cancer. Moreover, it may be possible to develop this procedure into a systemic therapy for tumor-specific targeting.
