Abstract
This study aimed to determine the effect of sulfur (S) application on a root-associated microbial community resulting in a rhizosphere microbiome with better nutrient mobilizing capacity. Soybean plants were cultivated with or without S application, the organic acids secreted from the roots were compared. High-throughput sequencing of 16S rRNA was used to analyze the effect of S on microbial community structure of the soybean rhizosphere. Several plant growth-promoting bacteria (PGPB) isolated from the rhizosphere were identified that can be harnessed for crop productivity. The amount of malic acid secreted from the soybean roots was significantly induced by S application. According to the microbiota analysis, the relative abundance of Polaromonas, identified to have positive association with malic acid, and arylsulfatase-producing Pseudomonas, were increased in S-applied soil. Burkholderia sp. JSA5, obtained from S-applied soil, showed multiple nutrient-mobilizing traits among the isolates. In this study, S application affected the soybean rhizosphere bacterial community structure, suggesting the contribution of changing plant conditions such as in the increase in organic acid secretion. Not only the shift of the microbiota but also isolated strains from S-fertilized soil showed PGPB activity, as well as isolated bacteria that have the potential to be harnessed for crop productivity.

Abstract
OBJECTIVE We examined the association between living alone and mental health and the moderating effects of face-to-face and non-face-to-face social contacts, among community-dwelling older adults. STUDY DESIGN Cross-sectional study. METHODS This cross-sectional study recruited Japanese adults older than 60 years, who attended health check-ups held in a suburban town hall in July and August of 2018 and 2019. As mental health outcomes, depression was assessed using the Geriatric Depression Scale 15-items, loneliness was assessed using the University of California, Los Angeles Loneliness Scale 3-items, and happiness was self-rated on a 10-point scale. Face-to-face social contacts were evaluated by participants' frequency of meetings with relatives or friends, whereas non-face-to-face contacts were measured by the frequency of interactions via letter, telephone or e-mail. Multivariable linear regression analysis was conducted to examine the association between living alone with each mental health outcome and the effect modifications of having face-to-face and non-face-to-face social contacts. RESULTS Data from 300 older adults were analysed. The participants' mean age was 73.0 years, 51.3% were female, and 16.0% lived alone. Living alone was significantly associated with poorer mental health. Regarding loneliness and low happiness, having face-to-face and non-face-to-face contacts more than once a week alleviated the adverse association of living alone (loneliness: face-to-face contacts, P = 0.020; non-face-to-face contacts, P = 0.028; happiness: face-to-face contacts, P = 0.020; non-face-to-face contacts, P = 0.001). CONCLUSIONS Our findings suggest that non-face-to-face, as well as face-to-face social contacts have a moderating effect on the adverse association of living alone with loneliness and happiness.

Abstract
BACKGROUND The INBUILD trial investigated the efficacy and safety of nintedanib versus placebo in patients with progressive fibrosing interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF). We aimed to establish the effects of nintedanib in subgroups based on ILD diagnosis. METHODS The INBUILD trial was a randomised, double-blind, placebo-controlled, parallel group trial done at 153 sites in 15 countries. Participants had an investigator-diagnosed fibrosing ILD other than IPF, with chest imaging features of fibrosis of more than 10% extent on high resolution CT (HRCT), forced vital capacity (FVC) of 45% or more predicted, and diffusing capacity of the lung for carbon monoxide (DLco) of at least 30% and less than 80% predicted. Participants fulfilled protocol-defined criteria for ILD progression in the 24 months before screening, despite management considered appropriate in clinical practice for the individual ILD. Participants were randomly assigned 1:1 by means of a pseudo-random number generator to receive nintedanib 150 mg twice daily or placebo for at least 52 weeks. Participants, investigators, and other personnel involved in the trial and analysis were masked to treatment assignment until after database lock. In this subgroup analysis, we assessed the rate of decline in FVC (mL/year) over 52 weeks in patients who received at least one dose of nintedanib or placebo in five prespecified subgroups based on the ILD diagnoses documented by the investigators: hypersensitivity pneumonitis, autoimmune ILDs, idiopathic non-specific interstitial pneumonia, unclassifiable idiopathic interstitial pneumonia, and other ILDs. The trial has been completed and is registered with ClinicalTrials.gov, number NCT02999178. FINDINGS Participants were recruited between Feb 23, 2017, and April 27, 2018. Of 663 participants who received at least one dose of nintedanib or placebo, 173 (26%) had chronic hypersensitivity pneumonitis, 170 (26%) an autoimmune ILD, 125 (19%) idiopathic non-specific interstitial pneumonia, 114 (17%) unclassifiable idiopathic interstitial pneumonia, and 81 (12%) other ILDs. The effect of nintedanib versus placebo on reducing the rate of FVC decline (mL/year) was consistent across the five subgroups by ILD diagnosis in the overall population (hypersensitivity pneumonitis 73·1 [95% CI -8·6 to 154·8]; autoimmune ILDs 104·0 [21·1 to 186·9]; idiopathic non-specific interstitial pneumonia 141·6 [46·0 to 237·2]; unclassifiable idiopathic interstitial pneumonia 68·3 [-31·4 to 168·1]; and other ILDs 197·1 [77·6 to 316·7]; p=0·41 for treatment by subgroup by time interaction). Adverse events reported in the subgroups were consistent with those reported in the overall population. INTERPRETATION The INBUILD trial was not designed or powered to provide evidence for a benefit of nintedanib in specific diagnostic subgroups. However, its results suggest that nintedanib reduces the rate of ILD progression, as measured by FVC decline, in patients who have a chronic fibrosing ILD and progressive phenotype, irrespective of the underlying ILD diagnosis.

Abstract
Chronic airway diseases like COPD and asthma are usually accompanied with airway fibrosis. Myofibroblasts, which are characterized by expression of smooth muscle actin (α-SMA), play an important role in a variety of developmental and pathological processes, including fibrosis and wound healing. Sphingosylphosphorylcholine (SPC), a sphingolipid metabolite, has been implicated in many physiological and pathological conditions. The current study tested the hypothesis that SPC may modulate tissue remodeling by affecting the expression of α-SMA in human fetal lung fibroblast (HFL-1) and fibroblast mediated gel contraction. The results show that SPC stimulates α-SMA expression in HFL-1 and augments HFL-1 mediated collagen gel contraction in a time- and concentration-dependent manner. The α-SMA protein expression and fibroblast gel contraction induced by SPC was not blocked by TGF-β1 neutralizing antibody. However, it was significantly blocked by S1P2 receptor antagonist JTE-013, the Rho-specific inhibitor C3 exoenzyme, and a Rho-kinase inhibitor Y-27632. These findings suggest that SPC stimulates α-SMA protein expression and HFL-1 mediated collagen gel contraction via S1P2 receptor and Rho/Rho kinase pathway, and by which mechanism, SPC may be involved in lung tissue remodeling.

Abstract
Abstract
The incidence of breast cancer in Japanese women has doubled in all age groups over the past two decades. We recently demonstrated that this marked increase is mostly due to an increase in the estrogen receptor (ER)-positive subtype, and we created risk prediction models for ER-positive breast cancer in both pre- and post- menopausal women using genetic factors (single nucleotide polymorphism (SNP)), environmental risk factors, serum hormones and growth factors by logistic regression analysis. Serum level of testosterone, which is the precursor of estradiol in estradiol synthesis, was found to be a risk predictor in both pre- and post- menopausal women. On the other hand, it has been reported that some SNPs, including those of estrogen-related genes such as ESR1 and CYP17A1, are correlated with breast cancer risk by genome-wide association studies. To acquire some insights into this mechanism, we analyzed genetic factors (14 SNPs), serum hormones and growth factors (estradiol, testosterone, prolactin, insulin-like growth factor 1 (IGF1) and IGF binding protein 3 (IGFBP3)) in 913 women with breast cancer and 278 disease-free controls for correlation between them.
Serum testosterone and prolactin levels were significantly higher in ER-positive breast cancer patients than in disease-free controls in both pre- (p<0.0001, p<0.0001) and post- (p<0.0001, p = 0.007) menopausal women, and serum estradiol level was significantly higher in ER-positive breast cancer patients than in disease-free controls only in premenopausal women (p = 0.0005). There were significant differences in serum hormone levels among the women with each SNP genotype (homozygotes of major allele, heterozygotes and homozygotes of minor allele), including testosterone among rs743572 genotype (p = 0.014), estradiol among rs827421 genotype (p = 0.016), IGF-1 among rs6905370 genotype (p = 0.032), and prolactin among rs1042522 genotype (p = 0.035) in premenopausal women, as well as estradiol among rs3803662 genotype (p = 0.027) and IGFBP3 among rs6905370 genotype (p = 0.036) in postmenopausal women. In particular, serum testosterone level was significantly different among the rs743572, which is one of the enzymes that convert testosterone to estradiol, of genotypes (AA: 0.308 +/- 0.180 ng/ml, AG: 0.319 +/- 0.193 ng/ml and GG: 0.380 +/- 0.187 ng/ml, p = 0.014). On the other hand, the rs743572 heterozygotes of CYP17A1 have been reported to have increased breast cancer risk than homozygotes of both the major allele and minor allele in premenopausal women. Further studies are required to clarify this mechanism.

Abstract
Local tumor compression is the main mechanical cause of posterior interosseous nerve (PIN) palsy. The reported cases of these tumors do not include that of pigmented villonodular synovitis (PVNS). Here, we report a case of a 53-year-old male with a 9-year history of painless swelling in his left elbow and a few months of progressive weakness in his left hand. Imaging identified the mass, and histological examination of the biopsy specimens revealed PVNS. The mass was compressing the nerve at the arcade of Frohse, and we performed a complete resection of the mass. Following removal of the mass, the patient regained complete function in his left upper extremity, and no local recurrence has been detected after 2 postoperative years. The possibility of PVNS should be considered in the differential diagnosis of PIN palsy.

Abstract
Abstract
The incidence of breast cancer in Japanese women has doubled in all age groups over the past two decades, making it important to evaluate breast cancer risk factors in Japanese women. It is well known that mammographic density is positively associated with breast cancer risk in Western countries, and mammographic density is known to be affected by some environmental factors, serum hormones, and growth factors. We performed stepwise variable selection in a multiple regression model with fifteen independent variables as described below, based on the Akaike information criteria (AIC) to build a mammographic density prediction model using a dataset of 1191 women (913 women with breast cancer and 278 disease-free controls). The variables included were: environmental risk factors (body-mass index (BMI), age at menarche, pregnancy, age at first birth, breastfeeding, family history of breast cancer, age at menopause, use of hormone replacement therapy, alcohol intake and smoking), serum hormones and growth factors (estradiol, testosterone, prolactin, insulin-like growth factor 1 (IGF1) and IGF binding protein 3 (IGFBP3)) and mammographic density. The resulting prediction model is:
Mammographic density = + 0.000476 (IGF1) −0.0605 (testosterone) − 0.0508 (IGFBP3) − 0.00683 (age) − 0.0175 (BMI) + 0.00883 (age at menarche) − 0.0153 (breast feeding), (R2 = 0.336).
In this model, IGF1, testosterone, IGFBP3, age, BMI, age at menarche, and breastfeeding were considered to be important factors. IGF1 and age at menarche were positively associated with mammographic density, while on the other hand testosterone, IGFBP3, age, BMI, and breast feeding were negatively associated with mammographic density. Further studies are required to build a modified model incorporating serial measurements of serum hormones and growth factors to take into account time-dependent changes of serum hormones and growth factors, and to assess its accuracy.

Abstract
A study was carried out to examine modifying effects of Maharishi Amrit Kalash 4 (MAK 4) and Maharishi Amrit Kalash 5 (MAK 5) on phagocytic and digestive functions of macrophages in male ICR mice. Mice at 4 week of age were divided into 3 groups: no treatment group (control), MAK 4 treated group (MAK 4 group) and MAK 5 treated group (MAK 5 group). MAK 4 and MAK 5 were given p.o. at 50 mg/kg per day (5 days/week) for 7 weeks. Phagocytic function of reticuloendothelial system evaluated by the carbon clearance was enhanced by the treatment of MAK 4 and MAK 5. Superoxide anion (O(2-)) production of peritoneal macrophages increased significantly in both MAK 4 and MAK 5 groups. The acid phosphatase activity of peritoneal macrophages increased significantly in MAK 4 group compared to the control group, but not in MAK 5 group. The activities of β-glucuronidase and lactate dehydrogenase in both MAK 4 and MAK 5 groups increased significantly when compared to the control group. These results suggest that MAK 4 and MAK 5 promote the phagocytic and digestive functions of macrophages and have a stimulatory effect on macrophages.

Abstract
This study was carried out to evaluate the dose-effects of ingestion of Maharishi Amrit Kalash 5 (MAK 5), an Ayurvedic food supplement, on the immune function in 10 week female inbred BALB/c mice. Superoxide anion (O(2) ) production of peritoneal macrophages and the response of spleen cells to concanavalin A (Con A) were examined in mice given MAK 5 by gastric intubation of an aqueous emulsion at the doses of 10, 50, 100 and 200 mg/kg once a day for 20 days. Glucose consumption of peritoneal macrophages in the MAK 5-treated mice at all doses after 24 hours of incubation, and only at the dose of 200 mg/kg after 48 hours of incubation were significantly higher than those in the control group. O(2) production of peritoneal macrophages in the presence of stimulator was significantly higher in the MAK 5-treated group at the dose of 200 mg/kg than in the control group. Activities of β -glucuronidase and lactate dehydrogenase in the peritoneal macrophages were significantly increased in the MAK 5treated mice at all doses. MAK 5 did not enhance spontaneous splenic lymphocyte proliferation at any dose in mice. Stimulation indices in the MAK 5-treated groups at the doses of 50, 100 and 200 mg/kg were significantly higher than that of the control group. These results indicate that gastric intubation of MAK 5 once a day at the dose of 50 mg/kg enhances not only macrophage function but also lymphocyte responsiveness in mice.

Abstract
BACKGROUND The fraction of exhaled nitric oxide (FENO) is reduced by anti-inflammatory treatment in asthma. However, the FENO level is also regulated by individual demographics and there is considerable variation among clinically stable patients. OBJECTIVE We hypothesized that some demographics may be responsible for persistent FENO elevation despite inhaled corticosteroids (ICS) therapy in asthma. METHODS This was a prospective observational study. We initially screened 250 stable asthmatics and determined the FENO cut-off point for identifying poorly controlled asthma defined by one of the following criteria: Asthma control test <20, or forced expiratory volume in one-second % of predicted <80%, or peak expiratory flow variability <80% (Study 1). After 12-weeks, 229 patients who maintained high or low FENO were selected and the independent factors which might contribute to a high FENO were examined (Study 2). RESULTS A FENO level >39.5 p.p.b. yielded 67% sensitivity and 76% specificity for identifying the patients with poorly controlled asthma. The persistent high FENO group (≥ 40 p.p.b.) was more likely to be ex-smokers, to show evidence of atopy (positive specific IgE, higher serum IgE and blood eosinophils), and to have allergic comorbidities. Especially, past smoking history, blood eosinophils, and chronic rhinosinusitis were identified to be independent predictors of high FENO. Neither the dose of ICS nor other medication use showed any difference between the groups. CONCLUSIONS AND CLINICAL RELEVANCE These results suggested that past smoking history, blood eosinophilia, and chronic rhinosinusitis are involved in the persistent airway inflammation detected by FENO. Although their relative contributions on FENO values should be further quantified, clarification of the features of the subjects with high FENO might provide clues for adjustment of the treatment approach in asthma.

Abstract
Abstract
The incidence of breast cancer in Japanese women has doubled in all age groups over the past two decades. We have recently demonstrated that this marked increase is mostly due to an increase in the estrogen receptor (ER)-positive subtype. It is necessary to establish risk factors capable of predicting the risk of ER-positive breast cancer which will enable the efficient selection of candidates for preventive chemotherapy. We analyzed genetic factors, including 14 single nucleotide polymorphisms (SNPs), environmental risk factors (body-mass index (BMI), age at menarche, pregnancy, age at first birth, breastfeeding, family history of breast cancer, age at menopause, use of hormone replacement therapy, alcohol intake and smoking), serum hormones and growth factors (estradiol, testosterone, prolactin, insulin-like growth factor 1 (IGF1) and IGF binding protein 3 (IGFBP3)) and mammographic density in 913 women with breast cancer and 278 disease-free controls. To identify important risk factors, risk prediction models for ER-positive breast cancer in both pre- and postmenopausal women were created by logistic regression analysis. In premenopausal women, 1 SNP (CYP19A1-rs10046), age, pregnancy, breastfeeding, alcohol intake, serum levels of prolactin, testosterone and IGFBP3 were considered to be risk predictors. In postmenopausal women, 1 SNP (TP53-rs1042522), age, BMI, age at menopause, serum levels of testosterone and IGF1 were identified as risk predictors. Risk factors may differ between women of different menopausal status, and inclusion of common genetic variants and serum hormone measurements as well as environmental factors might improve risk assessment models. Further validation studies will clarify appropriate risk groups for preventive chemotherapy.

Abstract
Abstract
Background: microRNAs (miRNAs) have emerged as a new class of non-coding genes involved in regulating cell proliferation, differentiation, and viability. Recent studies have identified miR-210 among a set of hypoxia-regulated miRNAs and demonstrated a direct regulatory role of hypoxia-inducible factor-1 alpha (HIF-1 a) in its transcription. High expression of miR-210 has been reported to be a poor prognostic factor in several types of cancers including breast.
Materials and Methods: TaqMan MicroRNA assays for miR-210 expression were performed in 219 breast cancers (58 triple-negative (TNBCs), and 161 ER-positive and HER2−negative). Correlations between miR-210 expression and clinicopathological factors were analyzed. The effects of several variables on survival were tested by Cox proportional hazards regression analysis.
Results: miR-210 expression in TNBCs was significantly higher than in ER-positive and HER2−negative breast cancers (p<0.001). Patients whose TNBCs had low miR-210 expression experienced significantly better disease-free and overall survival compared with high miR-210 expressors (p=0.02 and p=0.05, respectively). Notably, among 40 node-negative TNBCs, 5-year disease-free survival was approximately 60% in patients whose tumors had high or intermediate miR-210 expression (n=26), while no patients with low miR-210 expression (n=14) suffered recurrent disease. Cox univariate and multivariate analyses demonstrated that low expression of miR-210 was an independent good prognostic factor in TNBCs.
Discussion: Although prognosis of patients with TNBCs is poor, those whose tumors expressed low levels of miR-210 had a more favorable prognosis. Thus, the degree of miR-210 expression might be a clinically useful prognostic factor for decision-making regarding treatment in the adjuvant setting, especially in node-negative TNBC patients.

Abstract
Mammalian p38 mitogen-activated protein kinases (MAPKs) are activated by various cellular stresses, as well as in response to inflammatory cytokines. In the central nervous systems (CNS), activation of the p38 MAPK pathway constitutes a key step in the development of several diseases, and the molecular mechanisms mediated by p38 MAPK signaling have been defined. Activation of this cascade releases pro-inflammatory cytokines that are known to be involved in cerebral ischemia, Alzheimer's disease (AD), Parkinson's disease (PD), multiple sclerosis (MS), neuropathic pain and depression. In AD, stimulated p38 MAPK may trigger the hyperphosphorylation of a neural microtubule-associated protein, tau. In addition, we have recently revealed that activation of p38 MAPK signaling decreases dendritic spine number, which may be associated with memory impairment after epileptic seizures. Thus, p38 MAPK can serve as a target for novel drug development for neural diseases. p38 MAPK inhibitors have been studied extensively in both preclinical experiments and clinical trials for inflammatory diseases. New p38 MAPK inhibitors are now being tested in phase II clinical trials for neuropathic pain and depression. Here, we review current and possible future applications of p38 MAPK inhibitors as therapeutic agents in neural diseases.

Abstract
Background: The incidence of breast cancer in Japanese women has doubled in all age groups over the past two decades. Patients and Methods: We examined the characteristics of patients and tumors treated in three time periods between 1982 and 2010. Estrogen receptor (ER), progesterone receptor (PgR), and HER2 status were assessed by immunohistochemistry. Correlation of hormone receptor levels with clinicopathological factors and prognosis was analyzed in ER-positive, HER2-negative breast cancer in two age groups (≥50 years vs. >50 years).
Results: A total of 1903 women with breast cancer, who were treated at Nagoya City University Hospital, were included in this study. The frequency of ER-positive breast cancer in women aged 50 years or younger increased greatly over the interval studied (1982-1991: 52.5%, 1992-2001: 72.6%, 2002-2010: 87.1%, P < 0.0001). The frequency of ER-positive tumors was also significantly increased in women over 50 years of age (1982-1991: 69.4%, 1992-2001: 73.3%, 2002-2010: 78.6%, P = 0.029). In ER-positive, HER2-negative breast cancer, tumor grade was negatively correlated with expression levels of ER (P = 0.0029) and PgR (P < 0.0001). Interestingly, PgR levels were significantly higher in women aged 50 years or younger than in women over 50 years old (P < 0.0001). In both age groups, the prognosis for patients with ER-positive, HER2- negative breast cancer significantly improved over time, due to advances in adjuvant therapies. ER and PgR expression levels were not associated with disease-free survival. Lymph node status and tumor size were strong prognostic factors regardless of the biological characteristics of the tumors in ER-positive, HER2-negative breast cancer in both age groups. Conclusions: It is necessary to establish risk factors, both genetic and environmental, capable of predicting the risk of ER-positive breast cancer and thus enable the efficient selection of candidates for hormone receptor-targeted chemoprevention. Furthermore, new approach should be considered to improve survival for node-positive, ER-positive breast cancer.

Abstract
The outcome and cause of death of each lung disease directly associated with rheumatoid arthritis (RA-LD) have been poorly investigated. A retrospective study was conducted of 144 patients with RA-LD, in whom the median follow-up period after the initial visit for a respiratory examination was 4.5 yrs. A total of 57 patients were identified with usual interstitial pneumonia (UIP), 31 with bronchiectasis, 16 with nonspecific interstitial pneumonia (NSIP), 11 with bronchiolitis, five with organising pneumonia (OP), five with diffuse alveolar damage (DAD) and 19 with combined disease. The 5-yr survival rates were 36.6% in the UIP group, 87.1% in the bronchiectasis group, 93.8% in the NSIP group, 88.9% in the bronchiolitis group, 60.0% in the OP group and 20.0% in the DAD group. Survival of patients with DAD was worse than that of patients with UIP. Overall, survival of patients with UIP was worse than that of patients with bronchiectasis, NSIP or bronchiolitis. Of the 144 patients, 71 (49.3%) died, of whom 58 (81.7%) died due to respiratory lesions. Of patients with RA-LD, patients with DAD experienced the highest mortality, and the survival of patients with UIP was worse than that of patients with NSIP.

Abstract
BACKGROUND Prolactin-induced protein (PIP) has been shown to bind to CD4 and is speculated to block CD4-HLA-DR interaction. However, the immunomodulatory effect of PIP on chronic allergic contact dermatitis (ACD) remains to be elucidated. OBJECTIVES To define the role of PIP during the immunoresponse. METHODS Using a low-dose oxazolone-induced mouse chronic ACD model, expression of PIP was examined immunohistologically. Furthermore, effects of continued exposure to a peptide mimicking the major binding site of PIP (amino acids 106-132) for CD4 was examined in a mouse chronic ACD model. RESULTS We clarified that keratinocytes, dermal infiltrating cells and spleen infiltrating mononuclear cells are positively stained with anti-PIP antibody. The PIP peptide significantly downregulated oxazolone-induced mouse ACD compared with controls. We also found that inflammation of the control ear, to which the PIP peptide had not been applied, was also suppressed in a synchronized manner in the late phase of ACD. CONCLUSIONS These findings suggest that PIP might have a local and systemic immunosuppressive effect in mouse chronic ACD.

Abstract
Abstract
Background: The combination docetaxel with cyclophosphamide (TC) regimen is one of standard treatment for early breast cancer patients. TC regimen has been widely used in Japan. However, a management for adverse event such as especially edema and nail/skin toxicity by docetaxel is very important due to give a completely full dosage. This multicenter phase II study was designed to evaluate the protection of nail and skin toxicity by using a frozen glove for early breast cancer patients treated by TC.Methods: Four cycles of docetaxel (75mg/m2) and cyclophosphamide (600mg/m2) administered intravenously (i.v.) every 21 days after surgery for primary breast cancer. All patients were attached frozen glove at right or left hand (protected hand) from 15 minutes before to 30 minutes after administration of docetaxel. The other hand (control hand) of same patient is not attached frozen glove between a administration of TC. Safety was assessed every cycle after the start of treatment. Primary endpoint is comparison the rates of nail and skin toxicity between protected and control hand. Secondary endpoints are feasibility of adjuvant TC regimen and adverse events by frozen glove in Japanese women.Results: Fifty two patients were enrolled from September 2007 to June 2008. The nail changes (grade 1 and 2) was occurred in 10 events (19.2%) and 19 events (36.5%) at protected and control hand, respectively. The skin toxicity was occurred in 14 events (26.9%, G1:8, G2:6) and 21 events (40.4%, G1:14, G2:7) at protected and control hand, respectively. The appearance of nail and skin toxicity was significantly decreased at protected hand than control hand (p=0.01). Overall, 41 patients (78%) completed the planned four cycles of TC without dose reductions or study discontinuation. One patient discontinued because of hematological toxicity defined as discontinuation by protocol. The dose reductions were necessary in 10(19%) patients because of hematological (febrile neutropenia) and non hematological toxicity by TC. Grade 3 and 4 adverse events (AEs) were neutropenia (G3:3.9%, G4:21.6%), febrile neutropenia (21.2%), fatigue (1.9%) and dermatitis (3.8%). Grade 1 or 2 AEs frequently observed (more than 20%) were dermatitis such as rash (45%, G1:29.4%, G2:15.7%), pigmentation, nausea, anorexia, disturbance of taste, tear dropping, fatigue, edema and peripheral sensory disturbance. However, there are no adverse events by frozen glove.Conclusion: TC is feasible regimen for early Japanese breast cancer patients after surgery. Frozen glove may be useful procedure which protected the nail and skin toxicity. Furthermore, it is necessary to protect the severe dermatitis due to completely performed planned TC treatment after surgery in Japan.

Abstract
Abstract
Endocrine therapy is the most important treatment of choice for estrogen receptor-positive breast cancer. Potential mechanisms for resistance to endocrine therapy involve estrogen receptor (ER)-coregulatory proteins and cross-talk between ER and other growth factor-signaling networks. However, the factors and pathways responsible for endocrine therapy resistance, particularly resistance to aromatase inhibitors, have not been clearly established. Sixteen postmenopausal patients with ERΑ-positive primary breast cancer were treated daily with 25 mg of exemestane (an aromatase inhibitor) for 6 months. Expressions of ERΑ, ERΒ, progesterone receptor (PgR), androgen receptor (AR), AIB1, aromatase, EGFR, HER2, Ki67, cyclin D1, p53, Bcl2, Stat5 and IGFBP5, and phosphorylations of ERΑ serine (Ser) 118, ERΑ Ser167, Akt Ser473 and p44/42 MAPK threonine (Thr) 202/ tyrosine (Tyr) 204 were examined by immunohistochemistry on pretreatment tumor biopsies and posttreatment surgical specimens. Analyses were made to test for correlations with response to exemestane. Of the 16 patients, 7 responded and 9 retained stable disease. High-level expression of AIB1 and phosphorylation of Akt Ser473 were significantly associated with a better response to exemestane, suggesting that these factors could be considered as predictors of exemestane response. Expressions of ERΑ, ERΒ, PgR, aromatase, Ki67, cyclin D1 and p53, and phosphorylations of ERΑ Ser118, ERΑ Ser167 and p44/42 MAPK Thr202/Tyr204 were decreased, whereas expressions of Stat5 and IGFBP5 were increased in posttreatment specimens compared to the values in pretreatment biopsies. Thus, the analysis of factors involved in the estrogen-dependent growth-signaling pathways may be useful in identifying patients responsive to exemestane.

Abstract
Pleiotropic effects of statins have been reported to include inhibition of matrix metalloproteinase (MMP) release from macrophages and endothelial cells. We evaluated whether statins would inhibit MMP release from human lung fibroblasts, which play a major role in remodelling processes. Monolayer and three-dimensional (3D) collagen gel cultures of fibroblasts were used. Cytokines (tumour necrosis factor-alpha and interleukin-1alpha) were used to induce MMP release and mRNA expression. Collagen degradation induced by cytokines and neutrophil elastase (NE) was evaluated by quantifying hydroxyproline. Atorvastatin inhibited MMP-1 and -3 release and mRNA expression in both culture systems. Similar results were obtained with simvastatin and fluvastatin. In 3D cultures where cytokines also stimulated MMP-9 release, atorvastatin also inhibited MMP-9 release. In 3D cultures, cytokines together with NE induced collagen degradation, which was also inhibited by atorvastatin. The effect of atorvastatin was reversed by mevalonate and geranylgeranyl-pyrophosphate but not by farnesyl-pyrophosphate. The current data suggest that statins may modulate remodelling processes mediated by fibroblasts by inhibiting MMP release.

Abstract
Background Exhaled breath condensate (EBC) is thought to contain substances of the lower airway epithelial lining fluid (ELF) aerosolized by turbulent flow. However, contamination by saliva may affect the EBC when collected orally. Objective The purpose of this study was to compare the cytokine expression levels in EBC with those in saliva, and to clarify the influence of saliva on cytokine measurements of EBC. Methods EBC and saliva samples were obtained from 10 adult subjects with stable asthma. To estimate differences in the contents of substances between EBC and saliva, the total protein concentration of each sample was measured. Further, we also measured the total protein concentration of ELF obtained from another patient group with suspected lung cancer using a micro sampling probe during bronchoscopic examination and roughly estimated the dilution of EBC by comparing the total protein concentration of EBC and ELF from those two patient groups. The cytokine expression levels of EBC and saliva from asthmatic group were assessed by a cytokine protein array. Results The mean total protein concentrations in EBC, saliva and ELF were 4.6 μg/ml, 2,398 μg/ml and 14,111 μg/ml, respectively. The dilution of EBC could be estimated as 1:3000. Forty cytokines were analyzed by a cytokine protein array and each cytokine expression level of EBC was found to be different from that of saliva. Corrected by the total protein concentration, all cytokine expression levels of EBC were significantly higher than those of saliva. Conclusion These results suggest that the salivary influence on the cytokine assessment in EBC may be negligible.

RESULTS The mean total protein concentrations in EBC, saliva and ELF were 4.6 microg/ml, 2,398 microg/ml and 14,111 microg/ml, respectively. The dilution of EBC could be estimated as 1:3000. Forty cytokines were analyzed by a cytokine protein array and each cytokine expression level of EBC was found to be different from that of saliva. Corrected by the total protein concentration, all cytokine expression levels of EBC were significantly higher than those of saliva. CONCLUSION These results suggest that the salivary influence on the cytokine assessment in EBC may be negligible.

Abstract
BACKGROUND Regular use of long-acting bronchodilators is recommended for symptomatic COPD patients. A transdermal type of beta 2-agonist, tulobuterol, was recently developed. This agent shows the pharmacokinetic property of a sustained serum concentration for 24h. However, little has been reported about the bronchodilatory properties of this agent. OBJECTIVES The aim of the present study was to compare the bronchodilatory action of transdermal beta 2-agonist tulobuterol with that of inhaled long-acting beta 2-agonist salmeterol. METHODS An open-label, randomized crossover study was performed. Eleven patients with stable COPD were enrolled in the study. Tulobuterol (2mg/day) or salmeterol (50 microg, twice daily) was administered in a randomized, crossover manner. Forced expiratory volume in 1s (FEV1), forced vital capacity (FVC) and inspiratory capacity (IC) were measured before administration, every 2h from 12 to 24h, and at 36 h after the initial administration. RESULTS Transdermal beta 2-agonist tulobuterol showed an improvement in FEV1, FVC and IC after dosing compared with those at baseline. Salmeterol also improved all parameters of FEV1, FVC and IC, and showed a greater improvement compared with the transdermal beta 2-agonist tulobuterol (p<0.05). The values of the area under the curve (AUC) of FEV1, FVC and IC during the administration of tulobuterol were 2.98+/-1.05, 1.81+/-0.98, 0.75+/-0.85 L h, respectively, and during the administration of salmeterol they were 6.39+/-1.12, 6.61+/-1.34, 4.28+/-0.91 L h, respectively. CONCLUSION The transdermal beta 2-agonist tulobuterol showed bronchodilatory action for at least 24h by once daily administration. However, its bronchodilatory potency was about three times less than that of the inhaled beta 2-agonist salmeterol.

Abstract
The treatment of small-round-cell tumors (SRCT) in adult patients remains a challenge to clinicians. In the present study, we analyzed the feasibility and efficacy of high-dose chemotherapy (HDCT) followed by autologous peripheral blood stem-cell rescue as a consolidation therapy exclusively for patients with good disease control through a single regimen of induction chemotherapy and local therapy. Twenty-one patients (12 females, median age 22.0 years) were analyzed, including seven cases with rhabdomyosarcoma (RMS) and 14 cases with Ewing's family tumors (EFT). Overall, survival was 46% and failure-free survival (FFS) was 33% at 3 years. Patients with EFT had better FFS than those with RMS, with an estimated 3-year FFS of 50% (P<0.01). There was a single case of possible treatment-related death and two cases of secondary malignancies. This study cannot conclusively determine the beneficial effects of HDCT for improving treatment outcomes in adult SRCTs due to the small number of subjects. However, study findings suggest that a subgroup of patients with EFT may obtain prolonged survival benefits from this therapy.

Abstract
It has been reported that a functional polymorphism in the promoter of the RANTES gene (-403G/A) is associated with atopic dermatitis in a German population. Although there are several reports on the association of RANTES promoter polymorphisms (-403G/A and -28C/G) with asthma, the association of these polymorphisms with atopic dermatitis has not yet been confirmed in other populations. We therefore aimed to test whether the RANTES promoter polymorphisms relate to atopic dermatitis in a well-defined Japanese population. We conducted an association study of upregulating promoter polymorphisms of RANTES (-403G/A and -28C/G) in 389 patients with atopic dermatitis and 177 healthy control subjects. There was a significant association between the upregulating variant of RANTES -28G and atopic dermatitis, while -403A variant showed a significant association with atopic dermatitis with high IgE productivity. These results support a role for RANTES promoter polymorphisms in susceptibility to atopic dermatitis.

Abstract
Large mafs are transcriptional factors and members of the basic leucine zipper (b-Zip) superfamily. Since we previously identified expression of c-maf in mouse kidney, we presently investigated the mRNA expression profile in the kidney of c-maf gene knockout mice by using DNA microarray, and plasma glutathione peroxidase-3 (GPx3) was predominantly downregulated. We focused on the relation between the expression level of c-maf and GPx3 in vivo and in vitro. Since GPx3 is an antioxidant enzyme, oxidative stress was induced by exposing a culture cell derived from mouse renal tubules (mIMCD3) to hydrogen peroxide. Real-time PCR demonstrated that mRNA expression of both c-maf and GPx3 increased in parallel during exposure to oxidative stress in a time- and dose-dependent manner. Then, the mIMCD3 cells were transfected with c-maf-cDNA containing plasmid, which resulted in an increase in mRNA and protein expression of GPx3 compared with the control cells. Thus, c-maf may be transcriptional regulator of GPx3 expression and modulate the antioxidative pathway in the kidney.

Abstract
Compared to young patients with Takayasu's arteritis (TA), little information about elderly patients with TA has been reported. Additionally, no reports were found regarding TA cases with complications of intestinal amyloidosis. This is a case report of an elderly female, who developed intestinal amyloidosis, during late-stage TA. After years of outpatient management, she developed sudden severe dyspnea with pulmonary effusion, requiring hospitalization. After this event, betamethasone was replaced by methotrexate (MTX) for the next 34 months, but it seemed ineffective. After 1.5 years, she developed intractable diarrhea, followed by increases in BUN and serum creatinine (Cr), requiring several courses of hemodialysis. Colonoscopy revealed the presence of amyloid in her intestine, although she died of complicated sepsis caused by MRSA infection. This may be the first paper describing intestinal amyloidosis in a TA patient. Additionally, her case is rare in that she lived more than 30 years after the onset and diagnosis of TA.

Abstract
BACKGROUND There have been several histological studies of the Leeds-Keio ligament in anterior cruciate ligament reconstruction, but there have been few of the Leeds-Keio ligament in the extra-articular portion. AIMS/METHODS To report the histological and ultrastructural findings of two cases of medial patellofemoral ligament reconstruction using the Leeds-Keio ligament, removed 6.1 years and 8.7 years after implantation. RESULTS In both cases, the tissue over the Leeds-Keio ligament was a ligament-like tissue. Electron microscopy showed that the diameter of the collagen fibrils in the tissue over the Leeds-Keio ligament was unimodal in the case investigated 6.1 years after implantation but bimodal in the case investigated after 8.7 years. CONCLUSIONS The tissue over the Leeds-Keio ligament may continue to grow with prolonged periods of mechanical stress.

Abstract
Between 1992 and 1999, we treated 350 patients with skeletal metastases. A multivariable analysis of the patients was conducted using the Cox proportional hazards model. We identified five significant prognostic factors for survival, namely, the site of the primary lesion, the performance status (Eastern Cooperative Oncology Group status 3 or 4), the presence of visceral or cerebral metastases, any previous chemotherapy, and multiple skeletal metastases. The score for each significant factor was derived from the corresponding estimated regression coefficients (natural logarithm of the hazard ratio). The prognostic score was calculated by adding all the scores for individual factors. The rate of survival was 31% at six months and 11% at one year for the patients with a prognostic score of 6 or more. By contrast, patients with a prognostic score of 2 or less had a rate of survival of 98% at six months and 89% at one year. This scoring system can be used to determine the optimal treatment for patients with pathological fractures or epidural compression.

Abstract
BACKGROUND Atopic dermatitis (AD)-specific genes have not yet been clarified. Objectives To identify gene expression specific to active atopic skin lesions. METHODS We analysed 23,000 genes in skin biopsy samples from 17 patients with AD and four normal controls using Affymetrix oligonucleotide arrays. RESULTS Four of the 10 genes with the greatest differences in expression between patients and controls, S100A8 and S100A7 (upregulated), and loricrin and filaggrin (downregulated), were epidermal differentiation genes located on 1q21, a locus previously reported to have a genetic linkage with AD. CONCLUSIONS Our results, showing downregulation of the cornified envelope genes and upregulation of the alternative keratinization pathway, are the first to suggest abnormal epidermal differentiation and defective defences as key abnormalities in AD.

Abstract
BACKGROUND Blood eosinophil levels in patients with atopic dermatitis vary widely during exacerbation of the disease. We considered that in addition to environmental factors, the genetic background involved with elevating blood eosinophil levels might be heterogeneous among atopic dermatitis patients. OBJECTIVE We attempted to determine whether a polymorphism of the interleukin (IL)5 gene plays a role in atopic dermatitis, particularly in those patients with blood eosinophilia. Due to the close relation of blood eosinophilia to high IgE productivity, we also assessed these polymorphisms in patients with high IgE concentrations. METHODS We determined the genotype of the IL5 polymorphism -703C/T in 451 atopic dermatitis patients and 116 normal subjects. The patients were classified into three groups by blood eosinophil levels; less than 7%, from 7 to 15%, and more than 15%, as well as by serum IgE concentrations; less than 500 IU/ml, from 500 to 2000 IU/ml, and more than 2000 IU/ml. RESULTS IL5 -703C/T was not significantly associated with either total atopic dermatitis patients or individual patients who had both blood eosinophilia and high IgE productivity. However, the distribution of the IL5 -703C/T genotype was significantly different between patients with either blood eosinophilia or high IgE productivity and those without either condition (P=0.0476, P=0.0088, respectively). CONCLUSION These results suggest that the IL5 gene may play a role in blood eosinophilia associated with atopic dermatitis. We also considered that the IL5 -703C/T gene polymorphism does not have a direct relationship to disease specificity.

Abstract
INTRODUCTION In the reconstruction of extensive bone defects after massive resection of malignant musculoskeletal tumors, the clinical results of moderately heat-treated autogenous bone graft have rarely been documented. We evaluated the remodelling and healing process of moderately heat-treated autogenous bone graft by means of imaging features. MATERIALS AND METHODS The subjects of this study were 19 patients with bone and soft-tissue tumors treated by heat-treated bone graft at our institution between 1992 and 2001, the mean follow-up period was 4.8+/-2.8 years (range 1-9 years). The remodelling and healing process of heat-treated bone graft was evaluated by means of radiography, bone scintigraphy, and MRI. RESULTS The mean period to obtain bone union between host bone and grafted bone was 9.4 months. Infection was noted in 1 patient, and fracture was present in 2 patients. In 6 patients, pseudoarthrosis was found. Bone scintigraphy showed an increased uptake at the host-graft junction in the period between 3 and 36 months (median 10.7 months) postoperatively. A gradually increased diffuse uptake on the grafted side was evident at an average of 29.1 months (range 19-41 months) postoperatively. High signal intensity on T2-weighted images was observed in the early period after surgery, and iso-intense or low signal intensity became evident after an average of 28.3 months. A gradually increased diffuse uptake on scintigraphy and iso-intense or low signal intensity on T2-weighted images indicated remodelling of the grafted bone. CONCLUSION Bone union of a moderately heat-treated autogenous bone graft was noted at about 9 months, and its remodelling was proceeding at about 30 months. This method will be useful for bone defects after massive resection of soft-tissue and bone tumors.

Abstract
AIM Liposarcoma is common soft tissue sarcoma that is sometimes difficult to treat, besides its good prognosis. The inter-alpha-trypsin inhibitor heavy chains (HCs) has been reported to be linked to hyaluronan, which play important roles in tumour progression and metastasis. In this study, clinical significance of HCs in patients with liposarcoma was investigated. METHODS HC expression was studied by immunohistochemistry on resected specimens of 33 liposarcoma patients and 10 lipoma patients. The expression of HC mRNA was analyzed by reverse transcription polymerase chain reaction (RT-PCR). Serum concentration of HC was determined with enzyme-linked immunosorbent assay (ELISA). RESULTS Prominent positive staining of HC was observed in extracellular matrix of pleomorphic and myxoid liposarcoma. In well-differentiated liposarcoma and lipoma, faint staining was seen with HC. No products of HC could be detected by RT-PCR. Serum concentration of HC was not up-regulated in any subtypes of liposarcoma. HC expression was not significantly correlated with tumour subtypes and prognosis. CONCLUSION HC was strongly accumulated in pleomorphic and myxoid liposarcoma, however, was not locally synthesized in liposarcoma. HC might play roles in stabilizing extracellular matrix, such as hyaluronan (HA), in liposarcoma.

Abstract
AIMS The aim of this study was to investigate telomerase activity and to assess the correlation between telomerase activity, tumor proliferative activity and p53 overexpression in osteosarcoma tumor samples. METHODS Using a telomerase polymerase chain reaction-enzyme-linked immunoassay based on the telomeric repeat amplification protocol method, we examined telomerase activity in 26 primary osteosarcoma specimens. P53 overexpression was identified using immunohistochemical staining, and tumor proliferative activity was assessed by immunohistochemical staining of PCNA. RESULTS Telomerase activity was detected at a relatively low level in five of 26 osteosarcoma tissue specimens. P53 was detected in eight of 21 cases. There was no significant correlation between telomerase activity and p53 overexpression (p=0.325). There was a significant correlation between PCNA staining and telomerase activity (p=0.0075). CONCLUSION Difference between the telomerase activity and p53 overexpression in osteosarcoma suggests that p53 and telomerase may not cooperate in tumor proliferation. Correlation of telomerase activity to PCNA expression suggests that telomerase activity may also useful for evaluate proliferative activity in osteosarcoma.
