Abstract
INTRODUCTION This retrospective cohort study examined the effects of the crossed raised arm (CRA) position in contrast-enhanced computed tomography (CECT) on contrast medium influx and image quality relative to the conventional position. METHODS Contrast medium influx into the collateral veins on CECT images was evaluated in 92 participants. The CT values of the pulmonary artery, descending aorta, and spleen were obtained in both positions and compared. Anatomical changes in the diameters and area of the subclavian vein and costoclavicular distance were also analyzed. RESULTS Contras 27 and 6 patients in the conventional and CRA positions, respectively. The influx risk ratio in the CRA position versus that in the conventional position was 0.22 (95% confidence interval, 0.10-0.51). Elevations in the median CT value of the pulmonary artery, descending aorta, and spleen in the CRA position were 7.0% (p < .001), 7.4% (p < .001), and 9.8% (p < .001), respectively. Enlargements in the major and minor diameters of the subclavian vein, subclavian vein area, and costoclavicular distance in the CRA position versus those in the conventional position were 19.3% (p < .001), 28.1% (p < .001), 53.6%, and 30.0% (p < .001), respectively. CONCLUSION The CRA position effectively prevented contrast medium influx into the collateral veins due to SVS and increased CT values in the target organs in CECT. The diameters and area of the subclavian vein and costoclavicular distance were enlarged at the thoracic outlet, which improved the flow of the contrast medium into the targeted organs. IMPLICATIONS FOR PRACTICE The CRA position can contribute to obtaining better CECT images during common clinical assessments at no additional cost.

Abstract
Luliconazole, recently launched in Japan, is a novel topical imidazole antifungal agent for the treatment of onychomycosis. Using in vitro onychomycosis model, the effect of luliconazole on the morphology of the growing hyphae of Trichophyton mentagrophytes was investigated by scanning electron microscopy (SEM). The model was produced by placing human nail pieces on an agar medium seeded with conidia of T. mentagrophytes. After incubating the agar medium for 3 days, luliconazole was applied to the surface of the nail in which hyphal growth was recognized, then cultured for up to 24 h. The initial change after treatment with the drug was the formation of fine wrinkles on the surface of the hyphae, eventually, the hyphae were flattened, and after that, no hyphal growth was observed. On the other hand, when the nails were pretreated with luliconazole for 1 h, no hyphal growth was observed even after culturing for 24 h. This study suggests that luliconazole has a strong antifungal activity by inhibiting the ability of fungi to grow and the drug has both excellent nail permeation and retention properties.

Abstract
The International Space Station (ISS) is a closed facility that orbits the earth carrying not only its crew but also microorganisms. We have participated in microbiota analysis projects for the Japanese Experiment Module KIBO (ISS; operations nomenclature: Microbe-I, II, III, and IV) and were in charge of fungal screening. The interior of KIBO was sampled using swabs and microbe detection sheets (MDSs) for fungal detection. The dominant genera obtained by culture were Aspergillus and Penicillium. DNA analyses of the fungal biota using a clone library showed that KIBO was dominated by Malassezia, a fungal inhabitant of human skin. Three fungal species, Aspergillus sydowii, Penicillium palitans, and Rhodotorula mucilaginosa, which grew under microgravity in KIBO were observed under a field emission-scanning electron microscope on the ground. No novel phenotypic characteristics were noted. The results of antifungal susceptibility testing of all isolates did not differ significantly from previous reports of corresponding fungi. In Microbe-I (August 2009), MDSs were culture negative, while in the next stages the CFU of MDSs were 10 for Microbe-II (February 2011), 24 for Microbe-III (October 2012), and 151 for Microbe-IV (February 2015). These results indicated that fungi inside KIBO are increasing and expanding over time, and therefore continuous surveillance is crucial.

Abstract
BACKGROUND AND PURPOSE Urinary liver-type fatty-acid binding protein (L-FABP), which is a biomarker of kidney tubule injury, has been studied extensively and established as a risk marker of acute kidney injury (AKI). The aim of this study was to investigate whether kidney tubule injury is associated with the development of AKI and mortality in patients with acute ischaemic stroke. METHODS Acute ischaemic stroke patients hospitalized in the stroke care unit (SCU) within 24 h after symptom onset were prospectively investigated. AKI was defined on the basis of Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Baseline urinary L-FABP was measured on admission. We evaluated the associations among urinary L-FABP, incidence of AKI, and 90-day mortality adjusted for renal function, albuminuria and other potentially predictive variables, using multivariable analysis. RESULTS In total, 527 acute ischaemic stroke patients (342 men, median age 74 years) were enrolled in the study. Twenty-seven patients (5.1%) experienced AKI within 7 days of admission. In the univariate analysis, high urinary L-FABP level had positive associations with AKI [53.8 μg/g creatinine (Cr) vs. 3.9 μg/g Cr; P < 0.001] and 90-day mortality (15.5 μg/g Cr vs. 4.0 μg/g Cr; P < 0.001). In the multivariate analysis, elevated urinary L-FABP level (per 10-μg/g Cr increase) was independently associated with AKI (odds ratio 1.225, 95% confidence interval (CI) 1.083-1.454; P = 0.003) and 90-day mortality (hazard ratio 1.091, 95% CI 1.045-1.138; P < 0.001). CONCLUSION Urinary biomarkers of kidney tubule injury are independently associated with the development of AKI and 90-day mortality in patients with acute ischaemic stroke treated at the SCU.

Abstract
Ou-gon, an extract from Scutellaria baicalensis Georgi root, has been shown to exhibit pronounced antifungal activity. The present study aimed to identify antifungal components of Ou-gon and to determine their mechanism of action against pathogenic fungi. Antifungal activity was assessed by the microbroth dilution method using four common human pathogenic fungi, Trichophyton rubrum, Trichophyton mentagrophytes, Aspergillus fumigatus, and Candida albicans. Components of crude Ou-gon extract were separated by reversed-phase high-performance liquid chromatography. Active antifungal components were identified by liquid chromatography-electrospray ionization tandem mass spectrometry. Terminal deoxynucleotidyl transferase dUTP nick end-labelling assay, SYTOX® green uptake assay, determination of intracellular reactive oxygen species and mitochondrial membrane potential as well as microscopy (confocal laser microscopy, scanning and transmission electron microscopy) were used to probe the mode of action. Two components with potent antifungal activity, baicalein and wogonin, were identified in Ou-gon. Baicalein showed potent antifungal activity against the four fungi tested. Wogonin displayed antifungal activity against all four fungi except C. albicans. The components are considered to induce apoptosis-like programmed cell death via hyperproduction of reactive oxygen species. This study enhances our understanding of the antifungal activity of Kampo medicine, and may contribute to the development of new and safe antifungal therapeutics.

Abstract
Abstract
Background: Breast cancer is no longer a single disease with high molecular heterogeneity. Gene profiling has identified at least 4 subtypes: Luminal A, Luminal B, HER2-enriched and basal-like breast cancer. Moreover, immunohistochemistry (IHC) classification is now considered a surrogate for establishing breast cancer subtypes. In previous report Luminal A was defined as ER and PgR positive, HER2 negative, Ki-67 low and recurrence risk low based on the multi-gene-expression assay. The distinction between Luminal A-like and Luminal B-like can be made by either using a high Ki-67 value (≥20%) or a low PgR value (< 20%). In this study, patients with ER positive, HER2 negative and negative node were classified into 4 groups according to the PgR and the Ki-67 status (cutoff points: 20%) and examined retrospectively in relation to clinicopathological findings including the recurrence score (RS) and disease-free survival (DFS).
Methods: A total of 1866 invasive breast cancer patients from November 2001 to November 2016 were included in this study. The cases were classified as follows; LA as high PgR/low Ki-67 (850 cases), LB1 as high PgR/high Ki-67 (553 cases), LB2 as low PgR/high Ki-67 (226 cases), and LB3 as low PgR/low Ki-67 (237 cases). Out of all these cases, 1510 were treated with endocrine therapy alone. The median follow-up period was 78.1 months. Moreover, 23 of the cases underwent a 21-gene expression assay and the RS (< 25 and > 26) was compared with our classification.
Results: The median age was 57.4 years (range: 25 - 94). T1 tumors were more common in the LA group and rare in the LB2 group. Nuclear grade 3 and p53 overexpression were significantly correlated with LB2. Endocrine therapy alone was performed in 87.4% (LA), 77.4% (LB1), 58.8% (LB2) and 86.9% (LB3), retrospectively. There were significant differences in DFS between the LA group (5y DFS: 98%, 10 y DFS: 95.9%) and the LB2 group (5y: 89.9%, 10y: 83.6%; p<0.0001) or LB1 (5y: 94.9%, 10y: 89.5%; p<0.0001), but there was no difference with the LB3 group (5y: 98.6%, 10y: 94.7%; p=0.88). In the cases with endocrine therapy alone, LA showed a similar DFS with LB3 (p=0.25). LB2 had a significantly worse DFS in all the cases and in the cases with endocrine therapy. Chemotherapy was administered to cases with a higher nuclear grade in combination with endocrine therapy. In the LB2 group, there was no difference in DFS between the cases with endocrine therapy and in the cases with chemo-endocrine therapy. Moreover, most of the cases with LA (1/1) and LB1 (15/16) had a RS of <25, and all of the LB2 (6/6) cases had a RS of >26.
Conclusion: The patients with LA and LB3 (both: Ki-67<20%) had a favorable DFS even in the endocrine therapy alone group. However, LB1 and LB2 (both: Ki-67≥20%) had a poorer DFS. Moreover, LB2 (PgR<20% and Ki-67≥20%) was significantly correlated with a higher degree of malignancy and benefited from chemotherapy. LA and LB3 with low Ki-67 values were considered to be a part of the Luminal A group. These data suggest that PgR and the Ki-67 status are useful in predicting prognosis and deciding the treatment strategy for patients with ER-positive and HER2 negative breast cancer.

Abstract
BACKGROUND It has been demonstrated that negatively distorted self-referential processing, in which individuals evaluate one's own self, is a pathogenic mechanism in subthreshold depression that has a considerable impact on the quality of life and carries an elevated risk of developing major depression. Behavioural activation (BA) is an effective intervention for depression, including subthreshold depression. However, brain mechanisms underlying BA are not fully understood. We sought to examine the effect of BA on neural activation during other perspective self-referential processing in subthreshold depression. METHOD A total of 56 subjects underwent functional magnetic resonance imaging scans during a self-referential task with two viewpoints (self/other) and two emotional valences (positive/negative) on two occasions. Between scans, while the intervention group (n = 27) received BA therapy, the control group (n = 29) did not. RESULTS The intervention group showed improvement in depressive symptoms, increased activation in the dorsal medial prefrontal cortex (dmPFC), and increased reaction times during other perspective self-referential processing for positive words after the intervention. Also, there was a positive correlation between increased activation in the dmPFC and improvement of depressive symptoms. Additionally, there was a positive correlation between improvement of depressive symptoms and increased reaction times. CONCLUSIONS BA increased dmPFC activation during other perspective self-referential processing with improvement of depressive symptoms and increased reaction times which were associated with improvement of self-monitoring function. Our results suggest that BA improved depressive symptoms and objective monitoring function for subthreshold depression.

Abstract
Lactic acid bacteria (LAB) have high immune system-stimulating activity and are considered beneficial for human health as probiotics in the gut. The innate immune system is highly conserved between mammals and insects. Microbe-associated molecular patterns (e.g., peptidoglycan and β-glucan) induce cytokine maturation, which, in silkworm larvae, leads to muscle contraction. The purpose of this study is to find a novel probiotic by using silkworm muscle contraction assay. In the present study, we isolated LAB derived from rice bran pickles. We selected highly active LAB to activate the innate immune system of the silkworm, which was assayed based on silkworm muscle contraction. Of various LAB, L. paraplantarum 11-1 strongly stimulated innate immunity in the silkworm, leading to stronger silkworm contraction than a dairy-based LAB. Silkworms fed a diet containing L. paraplantarum 11-1 exhibited tolerance against the pathogenicity of Pseudomonas aeruginosa. These findings suggest that L. paraplantarum 11-1 could be a useful probiotic for activating innate immunity.

Abstract
Abstract
As for the HER2-positive breast cancer, there are many cases to be effective for neoadjuvant chemotherapy in comparison with other intrinsic subtypes. However, pCR is not provided by neoadjuvant chemotherapy in all cases. [Aim] This study evaluated the effectiveness of a therapeutic strategy that switches chemotherapy, based on Ki-67 tumor expression after initial therapy, relative to that of standard chemotherapy in patients with HER2-positive breast cancer. [patients and methods] Patients were randomly assigned to the control arm or the Ki-67 response-guided arm (Ki-67 arm). Primary tumor biopsies were obtained before treatment, and after three once-weekly doses of paclitaxel and trastuzumab to assess the interim Ki-67 index. In the control arm, paclitaxel and trastuzumab was continued for a total of 12 doses, regardless of the interim Ki-67 index. In the Ki-67 arm, subsequent treatment was based on the interim Ki-67 index. Early Ki-67 responders continued to received paclitaxel plus trastuzumab for a total of 12 doses, while early Ki-67 non-responders were switched to epirubicin plus cyclophosphamide every 3 weeks for three cycles with once-weekly trastuzumab for a total of 12 doses. The primary endpoint was the pathological complete response (pCR) rate. [Results] When 237 patients were enrolled, an interim analysis was conducted in 200 patients. There was almost linear correlation between the Ki-67 reduction rate at interim assessment and the pCR rate. The pCR rate in Ki-67 early non-responders in the Ki-67 arm (23.6%; 95% CI, 12.4 to 34.9) was inferior to that in the control arm (44.1%; 31.4 to 56.7; p=0.025). A strong correlation was not found between the Ki-67 reduction rate and the clinical response rate (Spearman's correlation coefficient 0.22).

Conclusions: The pCR rate in the Ki-67 arm was inferior to that in the control arm.

The standard chemotherapy protocol remains as the recommended strategy for patients with HER2-positive breast cancer.

Abstract
We screened lactic acid bacteria that exhibited high innate immunity-stimulating activity by monitoring muscle contraction activity in silkworms. Heat-treated fractions of lactic acid bacteria, Leuconostoc carnosum #7-2, Leuconostoc gelidum #4-2, and Leuconostoc mesenteroides 8/11-3, had high (250-460 units/mg) innate immunity-stimulating activity. These lactic acid bacteria proliferated in milk to concentrations of 1 × 106 colony forming unit/mL. The present findings suggest that the silkworm muscle contraction assay is useful for screening lactic acid bacteria with high innate immunity-stimulating activity, and that the assay can be used for the production of fermented foods made from milk.

Abstract
OBJECTIVE Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, with the risk of frailty and poor quality of life. This study aimed to clarify the clinical characteristics of sarcopenia and to investigate the effects of comprehensive cardiac rehabilitation (CCR), including nutrition, physical exercise and medication, in patients with cardiovascular disease (CVD). METHODS We retrospectively studied 322 inpatients with CVD (age 72±12 years). Muscle mass, muscle strength and physical performance were assessed before and after exercise training in patients with and without sarcopenia, which was defined as either a gait speed of <0.8 m/s or reduced handgrip strength (<26 kg in males and <18 kg in females), together with lower skeletal muscle index (SMI) (<7.0 kg/m2 in males and <5.7 kg/m2 in females). The actual daily total calorie and nutrient intake was also calculated. RESULTS Sarcopenia was identified in 28% of patients with CVD, these patients having a higher prevalence of symptomatic chronic heart failure and chronic kidney disease. SMI was significantly associated with protein intake and statin treatment. The ratio of peak VO2 and SMI was significantly higher in the statin treatment group. Handgrip strength, gait speed, leg weight bearing index, and nutritional intake improved after exercise training in patients both with and without sarcopenia. CONCLUSIONS The present findings suggest that CCR is a promising strategy for prevention and treatment of sarcopenia in patients with CVD.

Abstract
Background and Purpose: Superficial mycotic infections have been only poorly described in koalas and there are no reliable mycologically confirmed data regarding clinical isolation of dermatophytes in this animal. We report an 11-year-old female koala, kept in a zoo in Tokyo, Japan, and presenting with hyperkeratotic lesions and scaly plaques on forepaw claws and pads reminiscent of fungal infection. Case Report: Direct microscopy of the scrapings was indicative of a dermatophyte infection. By culture and subsequent repeated subculturing of clinical specimens on Sabouraud dextrose agar, Mycobiotic agar, and potato dextrose agar, two distinct strains with different colony morphotypes (designed as types I and II) were identified. Macroscopic and microscopic characteristics of the strains were suggestive of three different species, i.e. Microsporum canis, M. gypseum, and M. fulvum. However, partial sequencing of internal transcribed spacer (ITS) region of rDNA, translation elongation factor-1α (Tef-1α), and beta-tubulin (BT2) genes confirmed the identity of both isolates as M. gypseum. The animal was treated with a continuous terbinafine regimen (250 mg/kg) once daily for 12 weeks. Conclusion: To the best of our knowledge, the present report is the first confirmed case of dermatophytosis in a koala. The genetics underlying a variety of phenotypic traits in most classical dermatophyte species are unknown, and further studies are needed to understand this phenomenon.

Abstract
Introduction
The recent diagnostic modality such as MRI can diagnose a tiny breast lesion even in healthy contralateral breasts. Recently, the rate of contralateral prophylactic mastectomy (CPM) is on the rise in the United States. In Japan, the CPM has been started for selected patients with a high risk. In this study, we divided bilateral breast cancers into the synchronous and the metachronous group and then compared the clinical features and biology.
Patients and Methods
Out of 216 bilateral breast cancer patients who underwent surgery between 1995 and March 2015, there were 101 synchronous breast cancer cases and 115 metachronous breast cancer cases (interval to the second tumor > 1 year). The items examined were age, tumor size, lymph nodal status, histological type, and biological markers (ER, PgR, HER2, p53 and Ki-67 index values) in the cases with paired data.
Results
1. The incidence of metachronous tumors was relatively stable at 2.1–2.7% throughout the period. On the other hand, the incidence of synchronous tumors has increased to 4.4% in the most recent 5-year period and the median interval was 7.1 years.
2. There was no difference in the tumor size of both tumors in the synchronous group, but the second tumor was significantly smaller than the first tumor in the metachronous group (2.2cm to 1.7cm). The node negative rates showed no difference between two groups.
3. The cases with DCIS were seen in 20% and 25% of the synchronous group and 12% and 16% of the metachronous group. Most of the patients (94.3%) with invasive cancer received systemic adjuvant therapy in the metachronous group.
4. The ER positive rates of both tumors were 87.1% and 88.1% in the synchronous group and 71.6% and 68.4% in the metachronous group, respectively. The concordance rates were higher in the synchronous group (p=0.02). Moreover, there was a significant difference in ER positive rates between the two groups (p=0.01) and the ER negative tumors were more frequent in the second tumor of the metachronous group. The PgR negative tumors increased in the second tumor of metachronous cases. The shorter the interval (< 5years), the more the ER positive rate decreased (p=0.002). However, the longer interval did not correlate with the change of receptor status.
5. The Ki-67 index values significantly increased in the second tumor of the metachronous group, especially in the cases with a shorter interval. However, there was no difference in the synchronous group. The p53 overexpression rates significantly increased in the cases with a shorter interval.
6. The postoperative prognosis for the first tumor did not differ in both groups.
Conclusion
The incidence of synchronous bilateral breast cancer cases have increased but have remained relatively stable in the metachronous group. The concordance rates of the ER, PgR, Ki-67 and p53 status were higher in the synchronous group but the cases with negative ER, negative PgR, higher Ki-67 values and positive p53 increased in the second tumor of the metachronous group. These findings suggest that adjuvant systemic therapy played a important role in the treatment of bilateral breast cancer but the secondary tumor was more aggressive in the metachronous cases.

Abstract
Cross-Polarization with Variable Contact-time (CP-VC) is very efficient at ultra-fast MAS (νR ≥ 60 kHz) to measure accurately the dipolar interactions corresponding to C-H or N-H short distances, which are very useful for resonance assignment and for analysis of dynamics. Here, we demonstrate the CP-VC experiment with (1)H detection. In the case of C-H distances, we compare the CP-VC signals with direct ((13)C) and indirect ((1)H) detection and find that the latter allows a S/N gain of ca. 2.5, which means a gain of ca. 6 in experimental time. The main powerful characteristics of CP-VC methods are related to the ultra-fast spinning speed and to the fact that most of the time only the value of the dipolar peak separation has to be used to obtain the information. As a result, CP-VC methods are: (i) easy to set up and to use, and robust with respect to (ii) rf-inhomogeneity thus allowing the use of full rotor samples, (iii) rf mismatch, and (iv) offsets and chemical shift anisotropies. It must be noted that the CP-VC 2D method with indirect (1)H detection requires the proton resolution and is thus mainly applicable to small or perdeuterated molecules. We also show that an analysis of the dynamics can even be performed, with a reasonable experimental time, on unlabeled samples with (13)C or even (15)N natural abundance.

Abstract
Calcineurin is a serine/threonine protein phosphatase that consists of catalytic (calcineurin A) and regulatory (calcineurin B) subunits. The conserved protein plays important roles in various biological processes. Drug combination of fluconazole and the calcineurin inhibitor (FK506) showed synergistic effects against dermatophytes. In the current study, we identified the calcineurin A homologous gene (TmcanA) in the dermatophyte Arthroderma vanbreuseghemii (anamorph: Trichophyton mentagrophytes). Knockdown mutants were produced from A. vanbreuseghemii, resulting in a defection in growth properties in accordance with dose of the suppressing reagent. The TmcanA gene restored the ability of calcineurin A-deficient Cryptococcus neoformans strain to grow at elevated temperatures. Repression of TmcanA at 37°C resulted in severely stunted growth, suggesting that this protein plays a role in tolerance to elevated temperatures. In addition, TMCANA showed an interaction with high osmolarity glycerol (HOG) signalling pathway by governing the secretion of a secondary metabolite. Moreover, expression of the hydrophobin A gene (TmHF) decreased significantly under the TmcanA-repressive condition, suggesting that TMCANA is involved in its regulation. In conclusion, calcineurin A is a multifunctional gene that is involved in the regulation of several biological processes and therefore is worth being considered as a drug target for treatment of dermatophytoses.

Abstract
Two-dimensional (1)H{(13)C} heteronuclear correlation solid-state NMR spectra of naturally abundant solid materials are presented, acquired using the 0.75-mm magic angle spinning (MAS) probe at spinning rates up to 100 kHz. In spite of the miniscule sample volume (290 nL), high-quality HSQC-type spectra of bulk samples as well as surface-bound molecules can be obtained within hours of experimental time. The experiments are compared with those carried out at 40 kHz MAS using a 1.6-mm probe, which offered higher overall sensitivity due to a larger rotor volume. The benefits of ultrafast MAS in such experiments include superior resolution in (1)H dimension without resorting to (1)H-(1)H homonuclear RF decoupling, easy optimization, and applicability to mass-limited samples. The HMQC spectra of surface-bound species can be also acquired under 100 kHz MAS, although the dephasing of transverse magnetization has significant effect on the efficiency transfer under MAS alone.

Abstract
We show that Cross-Polarization with Variable Contact-time (CP-VC) allows an accurate determination of C-H dipolar interactions, which permits an easy detailed analysis of bond lengths and local dynamics, e.g. in biomolecules. The method presents a large dipolar scaling factor of 1/√2, leading to a better determination of dipolar interactions, especially for long C-H distances, and it allows the observation of very small local details such as those related either to CH(2) three spin systems, or even to hydrogen bonds. CP-VC is very simple to set up and very robust with respect to most experimental parameters, such as: rf-offsets, chemical-shift anisotropies, imperfect Hartmann-Hahn setting, and rf-inhomogeneity. The only required condition is the use of a sufficiently fast MAS spinning speed of at least ca. 60 kHz.

Abstract
Abstract
Introduction: The Ki-67 index value is a prognostic factor in primary breast cancer and is a proliferation marker that also distinguishes between luminal type A and type B breast cancer. Moreover, change in Ki-67 index value due to treatment and recurrence is considered to be important in treating breast cancer. The evaluative procedure in this study was on two levels; first, we examined whether the baseline Ki-67 value at the primary tumor is useful as a prognostic factor after recurrence, and second, we looked at the changes in the values after recurrence.
Patients and Methods: Immunohistochemical (IHC) analysis of the Ki-67 index was performed on 4701 patients with primary breast cancer from 1987 until March 2013 at Kumamoto City Hospital. Out of these patients, there were 666 consecutive cases with recurrence after primary surgery. The fraction of proliferating cells (positive for Ki-67) was based on a count of at least 500 tumor cells in the area including the hot spot, and the Ki-67 values were divided into 2 or 3 groups; <20% and ≥20% (and ≥50%). Items examined were ER, PgR, HER2, tumor size, nodal status at primary tumor, and recurrent site (soft tissue, bone and viscera) and disease-free interval (DFI). Cox's proportional hazard model was used to perform a univariate and multivariate analyses of the factors related to overall survival (OS) after recurrence. The median follow-up period was 65.9 months in the remaining survival group. In 101 recurrent cases from whom the recurrent lesion was resected, the change in biological markers (Ki-67, ER and PgR) were evaluated.
Results: The median Ki-67 value at baseline was 20% in all the cases and 27% in the recurrent cases. In terms of recurrent site, the values were low (23%) in patients with bone metastasis, whereas patients with liver or brain metastasis showed higher values (38% and 53%, respectively). Moreover, DFI was inversely correlated with Ki-67 values. Univariate and multivariate analyses were performed to identify the prognostic factors for OS after recurrence. The significant factors included tumor size, lymph node status, ER, PgR, DFI, recurrent site, and the Ki-67 index value. Among these factors, a multivariate analysis revealed that the Ki-67 index value at primary tumor was an independent significant factor. The hormone receptor positive rate from the primary tumor to recurrence decreased from 67.3% to 63.4% and 64.4% to 50% for ER and PgR, respectively. The Ki-67 index value increased significantly from a mean of 28.9% at primary tumor to 35.7% at relapse. Furthermore, the Ki-67 index value at primary tumor was a significant prognostic factor for OS after recurrence in this cohort.
Conclusion: The Ki-67 value at primary tumor was a significant prognostic factor for OS after recurrence. The Ki-67 index value increased significantly after recurrence. It is therefore important to take the Ki-67 index into consideration in the treatment and follow-up of breast cancer patients.

Abstract
Abstract
Background: Transcription of the progesterone receptor (PgR) gene is regulated by estrogen in the breast tissue. PgR loss is considered to be a result in the reduction of estrogen receptor (ER) activity, due to either low circulating estrogen in some older women or a high growth factor signaling. Among the ER-positive breast cancer patients, PR-negative cases frequently have a higher resistance to endocrine therapy, and have a poorer prognosis. Therefore, we examined the clinical significance of ER+/PgR- tumors in luminal/HER2 negative breast cancer and its relationship to menopausal status.
Methods: The sample for this study came from 1791 consecutive patients with HER2 negative primary breast cancer from January 2002 to March 2013. The ER and PgR expressions were evaluated using immunohistochemistry (IHC). 1586cases had ER+/PgR+ tumor, 205cases had ER+/PgR- tumor. The items examined were nuclear grade, Ki-67 index value, TP53, tumor size and number of lymph node involvement. The Ki-67 index value and TP53 were evaluated using IHC and the cut-off values were 20% and 50%, respectively. Recurrence free survival (RFS) and breast cancer-specific survival (BCSS) was calculated using the Kaplan-Meier method and evaluated by the log-rank test or generalized Wicoxon test in stage 1 and 2 breast cancer.
Results: In terms of the distribution of ER and PgR status, ER+/PgR- were frequently seen in postmenopausal patients (13.7% vs 6.8%, respectively). Patients with ER+/PgR-and HER2 negative tumors had significantly smaller tumors, lower Ki-67 values, and a lower nuclear grade in the postmenopausal group compared with those in the premenopausal group. Moreover, RFS trended to be better in the postmenopausal group (p = 0.06), but there was no significant difference. BCSS was significantly higher in the postmenopausal cases (p = 0.001). On the other hand, in patients with ER+/PgR+ tumors, there was no significant difference in RFS and BCSS between the post- and pre-menopausal groups.
Conclusion: The ER+/PgR- tumors were more commonly seen in postmenopausal patients. The biological characteristics of ER+/PgR- tumors were significantly different in terms of the Ki-67 index value, nuclear grade, and the prognosis (BCSS and RFS) between pre- and postmenopausal status. Moreover, the postmenopausal group had a more favorable biology and prognosis than the premenopausal group. Therefore, the findings in this study indicate that menopausal status is related to the biology and prognosis in patients with ER+/PgR- tumors.

Abstract
Abstract
Background: The Ki-67 labeling index (LI) is useful in determining the efficacy of chemotherapy for patients with ER-positive and HER2-negative breast cancer. However, standardization of Ki-67 assessment has not yet been established. In terms of the factors that may affect Ki-67 LI, recent studies have focused on inter-observer variability in the interpretation of these values and insufficient attention has been given to the importance of handling the tissue. Therefore, this study focused on the effect of tissue fixation on Ki-67 LI.
Methods:
The effects of several pre-analytical conditions on the Ki-67 LI were studied as follows;
(1) Type of fixation: Each 173 surgically excised tumors were fixed with either 10% neutral buffered formalin or 15% formalin on the same condition, followed by assessment of Ki-67 LI.
(2) Time of fixation: Each study was repeated more than three times to confirm the result.
A: Time to fixation: A part of tumor, sliced from the surgically excised tumor, was kept in 4° for several hours to overnight before formalin fixation. Ki-67 LI was compared between the tumor with immediate and delayed fixation.
B: Time of fixation:
Insufficient fixation: A part of tumor, sliced from the surgically excised tumor, was fixed with formalin for 3 hours, followed by preparation of a paraffin-embedded block. Ki-67 LI was compared between the tumor with proper and shorter fixation.
Prolonged fixation: Some pieces of slice were prepared from the surgically excised tumor, followed by each preparation of a paraffin-embedded block at a designated fixation period. Ki-67 LI was compared among each sample fixed in a different period of time.
(3) Surgically excised tumors on Ki-67 LI:
A: Effect of cutting onto the tumor before fixation: Ki-67 LI in each 595 surgically excised tumor with or without cutting onto the tumor before fixation, was analyzed.
B: Comparison between core needle biopsy and surgically excised tissue: Ki-67 LI in each 136 pairs of core needle biopsy and surgically excised tissue originated from the same tumor was compared.
Results:
(1) Ki-67 LI was significantly higher when 10% neutral buffered formalin was used as a fixative compared to 15% formalin (p = 0.018).
(2) Ki-67 LI was reduced in some degree when time to fixation was delayed, while insufficient fixation caused dramatic reduction of Ki-67 LI compared to that seen in an either ER or HER2. A prolonged period of fixation caused gradual reduction of Ki-67 LI associated with diminished nuclear labeling.
(3) Ki-67 LI was significantly higher in the tumor cut onto before fixation (p = 0.018). There was no significant difference in Ki-67 LI between core needle and surgically excised specimens (p = 0.107), when the tumor was properly fixed.
Conclusion: Our results suggest that pre-analytical setting critically influences the Ki-67 labeling. In order to standardize Ki-67 LI assessment in breast cancer, the care in handling of the pre-analytical tissue is crucial in determining accurate Ki-67 values.

Abstract
This study investigated the effects of cinnamaldehyde in combatting the hyphal growth of Candida albicans under varying concentrations, treatment times, and temperatures to determine the potential benefits of applying this substance to anti-Candida foods or gargles. From the results of pretreatment with cinnamaldehyde against Candida hyphae, we found that its inhibitory activity seemed to be strengthened in parallel with prolonged pretreatment time and a rise in temperature, and that pretreatment of 2,000 μg/ml for only 1 minute significantly inhibited the hyphal growth of C. albicans. We also demonstrated by XTT assay that pretreatment with cinnamaldehyde affected the metabolic activity of Candida hyphal cells. These findings suggest that a warm drink or mouthwash containing cinnamaldehyde might be a candidate as a prophylactic or therapeutic tool against oral Candida infection.

Abstract
We examined the viability and morphology of Candida albicans under experimental conditions after treatment with varying concentrations of cinnamaldehyde, the major component of cassia (Cinnamomum cassia), using XTT assay, fluorescent microscopy, scanning electron microscopy, and thin-section electron microscopy. At 10 μg/ml level, cinnamaldehyde inhibited mycelial growth, but did not affect the growth of yeast cells, metabolic activity, cell shape, or the ultrastructure of the cells. At 40 μg/ml level, cinnamaldehyde showed fungicidal activity accompanied by alteration of the membrane and interior of Candida cells. These findings indicate that cinnamaldehyde has both fungistatic and fungicidal activities against C. albicans and affects the structure of the cells.

Abstract
We examined the protective effect of radon inhalation on streptozotocin (STZ)-induced type-1 diabetes in mice. Mice inhaled radon at concentrations of 1000, 2500, and 5500 Bq/m3 for 24 hours before STZ administration. STZ administration induced characteristics of type-1 diabetes such as hyperglycemia and hypoinsulinemia; however, radon inhalation at doses of 1000 and 5500 Bq/m3 significantly suppressed the elevation of blood glucose in diabetic mice. Serum insulin was significantly higher in mice pre-treated with radon at a dose of 1000 Bq/m3 than in mice treated with a sham. In addition, superoxide dismutase activities and total glutathione contents were significantly higher and lipid peroxide was significantly lower in mice pre-treated with radon at doses of 1000 and 5500 Bq/m3 than in mice treated with a sham. These results were consistent with the result that radon inhalation at 1000 and 5500 Bq/m3 suppressed hyperglycemia. These findings suggested that radon inhalation suppressed STZ-induced type-1 diabetes through the enhancement of antioxidative functions in the pancreas.
