Abstract
Seasonal and local characteristics of perfluorinated alkylated substances (PFASs) were examined using size-segregated particles including an ultrafine range. The examination included sampling and analysis of ambient particles collected at four sites located in different environments in three different countries, Japan (Kanazawa and Okinawa), Hong Kong and India. To minimize the evaporation artefacts derived from PFASs during the sampling, an air sampler that permitted particles smaller than 0.1 μm (PM0.1) to be separated at a moderate pressure drop (<5-15 kPa), was used for all of the air sampling procedures. In the case of Kanazawa, a local city in Japan, the concentration of PFASs was found to be dominated by carboxylates, especially PFOA, PFNA and PFDA regardless of the particle size and sampling period. Ultrafine particles were found to be the largest contributor to the mass fraction of PFCAs, while the maximum PFOS mass fractions were determined to be in the coarse-sized fractions. The seasonal difference in the total PFAS concentration can be largely attributed to precipitation. The results were basically similar for all sites that were examined. The type of land use may be a more influencing factor on the mass fraction of the PFASs than the country of origin. The dependency of PFAS mass fraction on the specific surface of the particle suggests that ultrafine PFAS particles are segregated, not only by gas deposition but could also be segregated by a mechanism involving compositional dependence or the primary source of the particles. Other possible sources of PFASs, other than from traffic are also possible.

Abstract
OBJECTIVES The retention of the anti-rheumatic agent tocilizumab (TCZ) has not been well documented in patients with rheumatoid arthritis (RA). We conducted an observational study to compare the retention of TCZ and anti-tumour necrosis factor (TNF) drugs in the treatment of patients with RA. METHOD We reviewed continuation rates and causes of discontinuation of biological agents (biologics) by assessing medical records of patients with RA who were administered biologics at our institute from September 1999 to April 2012, using the Osaka University Biologics for Rheumatic Diseases (BiRD) registry. RESULTS A total of 401 patients were included. TCZ, infliximab (IFX), etanercept (ETN), and adalimumab (ADA) were administered to 97, 103, 143, and 58 patients, respectively. There were some differences between the baseline characteristics of the groups. The median duration (range) of TCZ, IFX, ETN, and ADA administration was 2.5 (0.1-12.6), 1.9 (0.0-7.7), 2.9 (0.0-11.3), and 1.3 (0.0-3.4) years, respectively. Continuation rates for TCZ and ETN were significantly higher than those for IFX and ADA. Multivariate analyses showed that discontinuation due to lack or loss of efficacy was significantly less common in the TCZ group than in the other groups. Discontinuation due to overall adverse events was not significantly different between treatment groups. CONCLUSION TCZ and ETN show better retention than IFX or ADA in the treatment of RA.

Abstract
Double-decker pulse radiolysis (DDPR), which utilizes double-decker electron beams, was investigated to develop a new pulse radiolysis with a high time resolution. The double-decker electron beams were generated by injecting two UV pulses into a photocathode radio-frequency gun. In the pulse radiolysis, one electron beam was used as a pump beam, and the other was converted to a probe pulse. Finally, as its first application, the DDPR was successfully used for observing solvated electrons in water, with a 10%-90% rise time of 8.6 ps.

Abstract
AbstractStatic corrosion tests of a powdered simulated waste glass were performed in the presence of magnetite under oxic and anoxic conditions, respectively. The corrosion tests under oxic conditions were performed in air, and those under anoxic conditions were performed in a glove box purged with mixed gas(Ar+5%H2). The experimental results showed that the presence of magnetite can enhance glass corrosion under both oxic and anoxic conditions, and the enhancement under anoxic conditions was small compared to that under oxic conditions. A large portion of the Si and insoluble elements were sorbed onto the magnetite surface, and the sorption under anoxic conditions was small compared to that under oxic conditions.It was suggested that the enhancement of glass corrosion by magnetite results from the sorption or precipitation of silica on the magnetite surface, which can be greatly affected by redox condition. Under anoxic conditions, it was suggested that precipitation of amorphous silica on the magnetite surface may be the dominant process for enhancement of glass corrosion in addition to sorption.

Abstract
Abstract
Background: Zoledronic acid (Zol) is the most potent inhibitor of bone resorption in bisphosphonates. In order to examine whether the inhibitory effect is involved in the mechanism of bone metastasis in breast cancer, a bone-seeking clone was examined. It was established by repeated sequential passages of metastatic cells from bone in nude mice and in vitro, and it exclusively metastasizes to bone with larger osteolytic lesions than MDA-MB-231 parental cells. Recent findings indicate that epidermal growth factor (EGF) signaling is also an important mediator of bone metastasis. We examined the synergistic effects of gefitinib on the proliferation and invasion of a bone-seeking clone compared with MDA-MB-231. Materials and Methods: The cellular proliferation was estimated using WST-1. Migration in the matrigel in a Boyden chamber was applied to the invasion assay.
Results: Treatment with 1 µM of Zol reduced 51% of cell proliferation in the bone-seeking clone; however, the inhibited rate was 37% in MDA-MB-231. The migration was also inhibited with 10 µM of Zol (bone-seeking clone: 69% reduction, MDA-MB-231: 54% reduction). The reduction rates of both assays by Zol treatment were significantly higher in the bone-seeking clone than in MDA-MB-231. Treatment with 10 µM of Zol plus 1 µM of gefitinib resulted in a proliferation reduction rate of 27% compared to that with 10 µM Zol treatment in the bone-seeking clone and no reduction in MDA-MB-231.
The migration reduction rate was 88% in the bone-seeking clone and no reduction in MDA-MB-231.
There was a significant difference between the bone-seeking clone and MDA-MB-231 in the reduction rates of both cellular proliferation and migration. Although the effect of gefitinib was synergistic with that of Zol in the bone-seeking clone, it was not clear in MDA-MB-231.
Conclusion: There appear to be at least two independent signaling pathways that occur in osteolytic bone metastasis. One is involved in the bone resorption of bisphosphonates, and the other is an EGFR signaling pathway. Clinically, the combination of Zol and gefitinib is suggested to be a strong therapy specific to bone metastasis.

Abstract
We have established the fact that the chrome reaction as well as the silver and osmium reactions are merely reductions by adrenalin. In our opinion the naming of the cells giving a positive reaction should not be based upon the reaction i.e., chromaffin cells), but on the presence of adrenalin itself. Biedl's terms, adrenal cell, adrenal organ, adrenal body, adrenal system, and also Bonnamour's term, adrenalin-producing cells, are appropriate in this respect. We propose the names adrenalin cell, adrenalin tissue, adrenalin system, thereby indicating the presence of adrenalin.

Abstract
L-proline (L-Pro) is a non-essential amino acid, and has become widely used as supplements and health foods, recently. A subchronic oral toxicity study of L-Pro was conducted with groups of 10 male and 10 female Fischer 344 rats fed a powder diet containing 0%, 0.625%, 1.25%, 2.5% and 5.0% of L-Pro for 90 days. No treatment-related clinical signs and mortality were noted. We observed no clear treatment-related effects with regard to body weight, food intake or urinalysis data. The average daily water intakes of the treated female groups were significantly increased compared to the controls. The hematology (red blood cell parameter) and serum biochemistry (glucose, blood urea nitrogen, creatinine or uric acid) of the treated male and/or female groups were lower than those of the control groups. However, these changes were lacked dose-dependence, and no abnormalities were found in corresponding pathological findings. In conclusion, the no-observed-adverse-effect-level (NOAEL) for L-Pro was determined to be a dietary dose of 5.0% (2772.9 mg/kg body weight/day for males and 3009.3mg/kg body weight/day for females) under the present experimental conditions.

Abstract
BACKGROUND Although vascular endothelial growth factor (VEGF)-A/VEGF receptor 2 (KDR) signalling may play a major role in the microangiopathy of systemic sclerosis (SSc), serum levels of soluble KDR (sKDR) in this disease have not yet been determined. OBJECTIVES To evaluate the possibility that serum sKDR levels can be a specific disease marker of SSc. METHODS Serum sKDR levels of 42 patients with SSc, 10 patients with Raynaud's phenomenon (RP) and 22 healthy controls were measured with specific enzyme-linked immunosorbent assays. Quantitative real-time polymerase chain reaction (PCR) was performed to determine KDR mRNA levels. RESULTS In females, the serum sKDR levels were significantly higher in patients with SSc, especially limited cutaneous SSc, than in patients with RP or healthy controls. Quantitative real-time PCR with RNA from skin sections revealed that KDR mRNA levels were also increased in the skin of patients with SSc with elevated serum sKDR levels. A significantly lower prevalence of pulmonary fibrosis, higher percentage vital capacity, and a higher incidence of telangiectasia were seen in female patients with SSc with elevated serum sKDR levels than those with normal levels. CONCLUSIONS These results suggest that the skin can be one of the sources of elevated serum sKDR levels, and that serum sKDR levels are useful for diagnosis and may be a marker of microangiopathy in patients with SSc, especially females. The VEGF-A/KDR signalling system may be involved in the pathogenesis of the disease.

Abstract #2061
The factors promoting the clinical aggressiveness of squamous cell carcinoma of the breast is still not well understood. In order to examine whether the mechanism of cell motility is involved in the aggressive behavior of squamous cell carcinoma, we established a squamous cell carcinoma cell line from breast primary (HBC 9) and assayed its invasiveness. The number of HBC9 cells migrating through matrigel was significantly increased by stimulation with epidermal growth factor (EGF). This enhancement of cell motility was distinctly detected in comparison with four ductal carcinoma cell lines (MCF7, BT474, HBC5, and MDA-MB-231). EGF stimulation also induced surface protrusions of HBC9 cells. To examine the interaction between Arp2/3 complex and N-WASP which is the final intracellular signal of invadopodia formation that is downstream from EGF stimulation, we observed surface protrusion of HBC 9 by laser microscopy. Co-localization of Arp2 and N-WASP was detected with actin polymerization visualized by phalloidin. Furthermore, the localization of cortactin was found to agree with that of N-WASP and Arp2/3 complex in the invadopodia. The cortactin gene copy number was evaluated using real time PCR by comparison between 12 DNA samples extracted from primary mammary squamous cell cancer tissue and those from corresponding normal breast tissue. A higher level of cortactin was detected in cancer tissue than in normal tissue in 10 cases (83%). At a protein level, intense immunostaining of cortactin was detected in all 12 cases, among which expression was confirmed in 2 cases by Western blot analysis. These results suggest that one of the causes of clinical aggressiveness of squamous cell carcinoma of the breast is the enhancement of cell motility by invadopodial formation. Overexpression of cortactin may result in the formation of invadopodium.

Toxic effects of l-aspartic acid at high dose levels on kidneys and salivary glands in Fischer 344 rats detected in a 90-day feeding study. Food Chem Toxicol 2008; 46:2789-95.

Abstract
A subchronic oral toxicity study of l-aspartic acid (l-Asp) was conducted with groups of 10 male and 10 female Fischer 344 rats fed a powder diet containing 0%, 0.05%, 1.25%, 2.5% and 5.0% concentrations for 90 days. Serum biochemistry showed treatment-related decreases of blood urea nitrogen, creatinine and uric acid levels in both sexes. In addition, incidences of urinary ketone and protein were significantly increased in treated both sexes, while relative kidney weight was significantly increased in the 5.0% male rat, and regenerative renal tubules with tubular dilation were histopathologically observed in male rats of the 2.5% or greater groups. The observed renal injury was confirmed not to be due to accumulation of alpha2u-globulin. Acinar cell hypertrophy of salivary glands was histopathologically evident in male and female rats of the 2.5% or greater groups. The present results indicate that l-Asp causes toxic effects on kidneys and possibly salivary glands at high dose levels in male and female Fischer 344 rats. Such toxic effects were observed only in animals given 2.5% and/or higher doses of l-Asp. In conclusion, the no-observed-adverse-effect-level (NOAEL) for l-Asp is 1.25% (696.6 mg/kg body weight/day for males and 715.2 mg/kg body weight/day for females) under the present experimental conditions.

Abstract
The metabolism and cytotoxic effects of tetrabromobisphenol A (TBBPA), a phenolic flame retardant, and its analogues were studied in freshly isolated rat hepatocytes and isolated hepatic mitochondria, respectively. The exposure of hepatocytes to TBBPA caused not only concentration (0.25-1.0 mM)- and time- (0-3 h) dependent cell death accompanied by the loss of cellular ATP, adenine nucleotide pools, reduced glutathione, and protein thiols, but also the accumulation of oxidized glutathione and malondialdehyde, indicating lipid peroxidation. TBBPA at a weakly toxic level (0.25 mM) was metabolized to monoglucuronide and monosulfate conjugates: the amounts of glucuronide rather than sulfate conjugate predominantly increased, accompanied by a loss of the parent compound, with time. In comparative effects based on cell viability, mitochondrial membrane potential and some toxic parameters, bisphenol A (BPA) was less toxic than TBBPA and tetrachlorobisphenol A (TCBPA), which are not significant differences in these parameters. In mitochondria isolated from rat liver, TBBPA and TCBPA caused an increase in the rate of State 4 oxygen consumption in the presence of succinate, indicating an uncoupling effect and a decrease in the rate of State 3 oxygen consumption in a concentration-dependent manner (5-25 microM). Taken collectively, our results indicate that (i) mitochondria are target organelles for TBBPA, which elicits cytotoxicity through mitochondrial dysfunction related to oxidative phosphorylation at an early stage and subsequently lipid peroxidation at a later stage; and (ii) the toxicity of TBBPA and TCBPA is greater than that of BPA, suggesting the participation of halogen atoms such as bromine and chlorine in the toxicity.

Abstract
19679 Background: From the good results of the ATAC trial and the ITA trial, standard hormonal therapy for postmenopausal breast cancer has changed from tamoxifen to aromatase inhibitor. However concerning the rate of skeletal-related events(SREs) including bone fracture, osteopenia and osteoporosis, a decrease in bone mineral density (BMD), It is reported that aromatase inhibitor cause higher than tamoxifen. According to the 2003 ASCO guidelines on the role of bisphosphonates in women with breast cancer, most women with newly diagnosed breast cancer are at risk of osteoporosis due to either their age or their breast cancer treatment. The purpose of the study is to investigate BMD of pretreatment Japanese women with breast cancer, and to investigate the efficacy of bisphosphonate for prevention from osteoporosis by aromatase inhibitor. Methods: From 2002, we have investigated BMD of 130 patients with breast cancer who underwent breast cancer operations in this hospital. BMD measurement was performed at A-P spine (L2–4) before treatment for breast cancer. The mean value of BMD for postmenopausal and premenopausal patients is compared with the value of average for Japanese women.Also we experienced 92 cases of postmenopausal breast cancer patients who were undergone breast cancer operations and take aromatase inhibitor after operations in this hospital. We selected 2 drugs. One is Anastrozole(ArimidexR) as an aromatase inhibitor, and the other is Alendronate(BonaronR) as a oral bisphosphonate drug. Results: The mean value of BMD for postmenopausal and premenopausal patients is 0.823 (vs. 0.90 for average) and 1.013 (vs. 1.03), respectively. This study shows that BMD of postmenopausal patients is trend lower than average. Tumor markers did not show significant difference. In the other study, the number of NTX which patients take Alendronate with Anastrozole decreased about 40% than which patients take Anastrozole alone. Also the rate of SRE is lower. Conclusions: The results suggest that the efficacy of bisphosphonates for prevention from SREs by aromatase inhibitor. Also BMD measurement seems significant for breast cancer patients before treatment including hormonal therapy. No significant financial relationships to disclose.
