Abstract
Blue spaces, especially as important urban natural environments, provide various benefits. Despite the increasing number of relevant papers, most recent studies have focused on the association between blue space environmental quality and health, with limited research assessing the environmental quality and user preferences of urban blue spaces. This study establishes a relationship between preference and environmental quality by investigating visitors' perception of the environmental quality of urban blue spaces (physical and aesthetic). For this purpose, 296 questionnaires were collected from three urban blue spaces and a multiple linear regression analysis was executed. Model results indicated that six of nine environmental quality components had a significant effect on preference scores, with "harmony" demonstrating the highest and "visual spaciousness & diversity" the lowest effect. The current study shown that two scales provided were used to measure users' perceived levels of the physical and aesthetic quality of the Urban Blue Spaces were acceptable. These results can help in the effective use of these natural capitals in cities and provide guidance for the environmental design of blue spaces.

Abstract
Many scholars have focused on Satoyama, which is characterized by mountains or villages away from the urban spaces. Our objective is to verify its psychophysiological effects on people performing usual Satoyama activities in ignored, small urban green spaces to help people find ways to stay healthy in post-coronavirus disease 2019 (COVID-19) society. In this study, 12 older adult volunteers from the "Forest around the Mountains" Nonprofit Organization and 12 young people from the university were invited as study subjects. They were asked to observe nature for 10 min and work for 30 min in the small green space "Forest around the Mountains". The Profile of Mood States 2nd Edition (POMS) and the State-Trait Anxiety Inventor (STAI) were used as psychological scales to detect their psychological restoration and blood pressure before and after the Satoyama activity. Their heart rate during the activity was used as the physiological indicator. The study showed that, as Satoyama volunteers, the older adults group had significant restorative psychophysiological effects during this experiment compared to the younger group; their systolic and diastolic blood pressure dropped significantly after Satoyama activities, On the other hand, the young group have been in the normotensive range before or after Satoyama activities The psychological indicators such as Anger-hostility, Confusion-bewilderment, and Tension-anxiety were significantly lower in the younger group but were still significantly higher than the indicators of the older adults. In general, this study found that Satoyama activities benefited young and older participants, especially older adults with high blood pressure. Satoyama activities in small urban green spaces are thus necessary and worth promoting in the post-COVID-19 era.

Abstract
BACKGROUND AND PURPOSE Noninvasive perfusion-weighted imaging with short scanning time could be advantageous in order to determine presumed penumbral regions and subsequent treatment strategy for acute ischemic stroke (AIS). Our aim was to evaluate interobserver agreement and the clinical utility of intravoxel incoherent motion MR imaging in patients with acute ischemic stroke. MATERIALS AND METHODS We retrospectively studied 29 patients with AIS (17 men, 12 women; mean age, 75.2 [SD, 12.0 ] years; median, 77 years). Each patient underwent intravoxel incoherent motion MR imaging using a 1.5T MR imaging scanner. Diffusion-sensitizing gradients were applied sequentially in the x, y, and z directions with 6 different b-values (0, 50, 100, 150, 200, and 1000 seconds/mm2). From the intravoxel incoherent motion MR imaging data, diffusion coefficient, perfusion fraction, and pseudodiffusion coefficient maps were obtained using a 2-step fitting algorithm based on the Levenberg-Marquardt method. The presence of decreases in the intravoxel incoherent motion perfusion fraction and pseudodiffusion coefficient values compared with the contralateral normal-appearing brain was graded on a 2-point scale by 2 independent neuroradiologists. Interobserver agreement on the rating scale was evaluated using the κ statistic. Clinical characteristics of patients with a nondecreased intravoxel incoherent motion perfusion fraction and/or pseudodiffusion coefficient rated by the 2 observers were also assessed. RESULTS Interobserver agreement was shown for the intravoxel incoherent motion perfusion fraction (κ = 0.854) and pseudodiffusion coefficient (κ = 0.789) maps, which indicated almost perfect and substantial agreement, respectively. Patients with a nondecreased intravoxel incoherent motion perfusion fraction tended to show recanalization of the occluded intracranial arteries more frequently than patients with a decreased intravoxel incoherent motion perfusion fraction. CONCLUSIONS Intravoxel incoherent motion MR imaging could be performed in < 1 minute in addition to routine DWI. Intravoxel incoherent motion parameters noninvasively provide feasible, qualitative perfusion-related information for assessing patients with acute ischemic stroke.

Abstract
Studies on green open space and ecological wisdom have developed over time and are linked to various subjects and impacts. However, both research subjects have developed somewhat independently despite their approaches often achieving a sustainable landscape. This paper proposed a bibliometric analysis of green open space and ecological wisdom research to identify the trends and hot topics on both aspects, then determine a potential topic for future research relating to both subject areas. We collected English research papers from the last decades from the Scopus database using appropriate keywords and analyzed the metadata using VOSviewer program. Then, the text data were extracted from the title and abstract of the document collections using VOSviewer built-in text mining function. The hot topic term was analyzed by calculating the score of the average citation based on their occurrences. Finally, potential research in green open space and ecological wisdom field was determined by overlaying the findings and catching the slice. A total of 283 document collections were analyzed and 75 most relevant terms were found. All the terms were divided into four clusters as a research field: urban green space cluster, environmental quality cluster, sustainable planning cluster, and landscape development cluster. Further, the hot topic analysis found ten keywords that had a high citation impact in document collection and mostly came from a sustainable planning cluster. After overlaying the findings, six terms emerged that have a high potential for future research because of their high citation impact for science.

Abstract
The objective of this study was to investigate the low temperature degradation characteristics of 2 types of high strength yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) in order to evaluate its suitability for implant body, implant superstructure or abutment. Disk-shaped conventional Y-TZP (0.25 mass% alumina) subjected to hot isostatic press treatment (HIP-Y-TZP) and Y-TZP/4Al2O3 with additional alumina (4.0 mass%) were mirror-polished. Accelerated aging tests with 134°C for 5 h at 0.2 MPa and 180°C for 5 h at 1.0 MPa were performed using an autoclave. Biaxial flexural strength and crystal phases were evaluated. Strength decreased as the proportion of monoclinic phase increased after accelerated aging treatment for both types of high-strength Y-TZPs. Despite the low alumina content, HIP-Y-TZP showed higher static strength and strength after accelerated aging treatment compared to Y-TZP/4Al2O3. However, both types of Y-TZP had adequate strength to be used as dental restorations even after accelerated aging treatment, therefore, its clinical suitability was considered high.

Abstract
BACKGROUND SPLIT was founded in 1995 in order to collect comprehensive prospective data on pediatric liver transplantation, including waiting list data, transplant, and early and late outcomes. Since 2011, data collection of the current registry has been refined to focus on prospective data and outcomes only after transplant to serve as a foundation for the future development of targeted clinical studies. OBJECTIVE To report the outcomes of the SPLIT registry from 2011 to 2018. METHODS This is a multicenter, cross-sectional analysis characterizing patients transplanted and enrolled in the SPLIT registry between 2011 and 2018. All patients, <18 years of age, received a first liver-only, a combined liver-kidney, or a combined liver-pancreas transplant during this study period. RESULTS A total of 1911 recipients from 39 participating centers in North America were registered. Indications included biliary atresia (38.5%), metabolic disease (19.1%), tumors (11.7%), and fulminant liver failure (11.5%). Greater than 50% of recipients were transplanted as either Status 1A/1B or with a MELD/PELD exception score. Incompatible transplants were performed in 4.1%. Kaplan-Meier estimates of 1-year patient and graft survival were 97.3% and 96.6%. First 30 days of surgical complications included reoperation (31.7%), hepatic artery thrombosis (6.3%), and portal vein thrombosis (3.2%). In the first 90 days, biliary tract complications were reported in 13.6%. Acute cellular rejection during first year was 34.7%. At 1 and 2 years of follow-up, 39.2% and 50.6% had normal liver tests on monotherapy (tacrolimus or sirolimus). Further surgical, survival, allograft function, and complications are detailed.

Abstract
Although the health benefits of urban parks have gained significant attention, the effects of viewing park landscape on older adult residents have not commanded much research. This study aimed to investigate the physiological and psychological effects of viewing cherry blossoms in spring and fresh greenery in early summer at urban parks. The experiments were conducted in two viewing spots in the same park in Japan during different seasons, and included 12 participants in both spring (mean age, 66.4 ± 10.5 years) and summer (mean age, 65.75 ± 10.1 years). Participants sat and viewed an urban park and city landscape for 11-15 min. Blood pressure was measured before and after the seated viewing while heart rate was measured continuously. Then, they evaluated the psychological responses using the Profile of Mood States and State-Trait Anxiety Inventory. Viewing cherry blossoms and fresh greenery in urban parks led to lower blood pressure in spring and early summer than viewing city areas in spring and early summer. Moreover, the score of vigor-activity was significantly higher; tension-anxiety was significantly lower in spring; and the state-anxiety level was significantly lower in early summer. The results of this study suggest that viewing urban parks results in physiological and psychological relaxation.

Abstract
The aim of this study was to better identify the information generated by citizens and to explore the regional social phenomenon whereby higher quality urban services focused on understanding regional issues are promoted. Citizens voluntarily and continuously communicate with local government both online and offline. We wanted to determine how civic information can be applied to urban planning. We selected Shiheung City, Republic of Korea, as our study area, as the city is formed of various types of land use: industrial areas, agricultural land, and residential areas. This area is facing developmental pressure with released development-restricted areas, and has been environmentally damaged by industrial complexes. We conducted a semantic network analysis of the top 10% most commonly used nouns in civil complaints to determine the keywords. Each thematic map we created was based on geographical information to explain the temporary, continuous, and chronic issues. The chronic problems were discussed in relation to the regional development process. The process of identifying and analyzing local issues by analyzing information voluntarily provided by citizens plays an important role in government-led urban management planning and policy formation and can contribute to decision making in the development of future urban policies.

Abstract
Environmental conservation activities such as biodiversity and natural resource management are supported by many eager volunteers in many countries. Because it takes a great deal of time and effort to train new members, volunteer programs are important for preventing the burnout of volunteers and maintaining their motivations to participate. This study explored whether motivations that inspire the future frequency of participation, which volunteers prefer, differ depending on the previous frequency of participation in conservation activities. Online surveys were chosen as the primary social research method to collect the relevant data, and 1500 responses were obtained from Japanese citizens who had participated in conservation activities. The findings suggest that improvement of personal physical well-being can have an influence on the variation in frequency of participation in the episodic group that participates only about once a year. The results also indicate that improvement of personal mental well-being and well-being for a local community can have an influence on the variation in frequency of participation in the irregular group that participates about every 2 months. Additionally, this study shows that interaction with other people and enjoyment of cultural services from ecosystems can have an influence on the variation in frequency of participation in many groups including the regular group that participates every month. These results represent valuable information that can be used as a reference for conducting conservation programs aimed at encouraging people to learn about nature conservation and interact with others to improve their local community.

Abstract
Context and Aims Japanese cuisine is now popular worldwide, and consumption of raw fish has thus increased at sushi bars and Japanese restaurants outside Japan. Anisakiasis, also known as herring-worm disease, is caused by ingesting larval nematodes in raw seafood and is a common illness in Japan. However, due to the rising popularity of Japanese food, gastroenterologists outside Japan need to be familiar with this disease. Subjects and Methods and Results We treated 158 patients presenting with acute gastrointestinal manifestations caused by anisakiasis from April 1991 to April 2000. One or more nematodes were removed endoscopically within 48 h of presentation in 44% of these patients, which resulted in prompt resolution of symptoms. Major endoscopic findings were gastric ulcer accompanied by hemorrhage, erosion, redness, and edema of the gastric mucosa in areas penetrated by larvae and other areas. Conclusions Endoscopy was valuable for the diagnosis and treatment of anisakiasis. We recommend endoscopy in suspected cases of anisakiasis. Moreover, it is desirable to combine complementary tests such as immunological tests/IgE measurement. As the popularity of Japanese cuisine increases, reports of anisakiasis are likely to be more frequent in countries other than Japan.

Abstract
Background Specific IgE (sIgE) is often used to predict oral food challenge (OFC) outcomes in food allergy, but interpretation of the results may vary depending on the assay method employed and the patient population tested. The aim of this study was to use two commercial assay systems to determine egg‐sIgE values predictive of allergy within the most common populations treated at pediatric clinics. Methods In a multicenter prospective study, 433 children with suspected or confirmed egg allergy underwent oral challenge (OFC) using cooked egg (CE) and raw egg (RE) powders to diagnose either true allergy in 1‐year‐old (group A, n = 220) or tolerance in 2‐ to 6‐year‐old (group B, n = 213). Egg white (EW)‐ and ovomucoid (OM)‐sIgE values were measured using the ImmunoCAP®sIgE (ImmunoCAP) and the IMMULITE® 2000 3 gAllergy™ (3gAllergy) systems. Children were recruited from six primary care clinics and 18 hospitals in Japan. Results Receiver‐operating characteristic (ROC) curve analysis yielded similar areas under the curve (AUC) for the two assays (0.7–0.8). The optimal cutoff values and the probability curves (PCs) of the sIgE by the two assays to predict CE and RE OFC outcomes were determined for both groups. Values for 3gAllergy were higher than for ImmunoCAP; however, correlation of sIgE and predicted probability calculated by PCs were strong between the two methods. Conclusions Cutoff values and PCs for egg‐sIgE established using both ImmunoCAP and 3gAllergy may be useful for predicting egg allergy in early childhood patient populations.

Abstract
BACKGROUND Dedifferentiated endometrioid adenocarcinoma (DEAC) of the uterus was first described by Silva et al. in 2006. The tumor has high-grade endometrial carcinoma component which abruptly emerged from low-grade areas. DEAC showed more aggressive phenotype than FIGO grade 3 endometrioid adenocarcinoma. However, there have been a few studies evaluating effectiveness of adjuvant therapy for the patients with DEC. CASE REPORT A 41-year-old case with Stage IVB DEAC that clinically showed resistance to several regimens of chemotherapy is reported. The uterine corpus tumor with size of 120 x 100 mm, and the metastases were found in lung, liver, and pelvic lymph nodes. She underwent supra-vaginal hysterectomy, left salpingo-oophorectomy, and partial resection of ileum. Pathologically, the tumor had both well differentiated and undifferentiated carcinoma components, and it was diagnosed as DEAC. After primary surgery, the patient received four regimens of adjuvant chemotherapy, however all regimens were judged as progressive disease. Subsequently, the patient died of disease seven months after surgery. CONCLUSION The present case of DEAC had an exceedingly poor prognosis, as was suggested in the several previous reports. The review of adjuvant therapeutic modalities revealed that there has been no effective therapy in the response-evaluable patients with DEAC. Further investigations for new strategy to treat the cases with DEAC are needed.

Abstract
Background: High-temperature-required protein A2 (HtrA2), a protein relating with apoptosis in a caspases-dependent and non-dependent manner, has been reported to be associated with chemosensitivity in several human cancers. Methods: Tissue microarrays made from 142 patients with high-grade serous ovarian adenocarcinoma were evaluated to assess whether HtrA2 expression was related with several clinical parameters. Results: Negative HtrA2 expression was observed in 36 cases (25%) of the patients, and related with significantly lower response rates of primary chemotherapy than those with positive HtrA2 expression (56% vs 83%, P<0.01). In addition, negative HtrA2 expression was identified as an independent worse prognostic factor for progression-free survival and overall survival by multivariate analyses. Furthermore, HtrA2 downregulation modulated sensitivity to platinum in serous ovarian cancer cells in vitro. Conclusions: HtrA2 expression was a predictor for sensitivity to chemotherapy, and could be a candidate of molecular target in the treatment of high-grade serous ovarian cancers.

Abstract
BACKGROUND Ovarian yolk sac tumor (YST) that is diagnosed during pregnancy is extremely rare. CLINICAL CASE A 22-year-old pregnant woman diagnosed with Stage IIIc YST at 17 weeks of gestation is presented. A 20-cm multilocular cystic tumor containing solid components with massive ascites was detected. Subsequently she underwent left salpingo-oophorectomy and cytoreductive surgery for peritoneal dissemination at 18 weeks of gestation, and the tumors were diagnosed as YST. After vaginal termination at 20 weeks of gestation, she received five cycles of combination therapy with bleomycin, etoposide, and cisplatin. There was no evidence of recurrence at 85 months after primary treatment. CONCLUSION Considering the rarity, treatment strategy for advanced-staged YST should be further investigated in international collaborative studies.

Abstract
In order to test the hypothesis about reduction in the deformation of the ligamentum flavum due to tension inside the ligamentum flavum, nonlinear finite element (FE) analysis was employed. As a preliminary analysis of natural tissue, nonlinear FE analysis was applied to a rubber plate. Assuming that the rubber is third-order Mooney-Rivlin model, the analysis and the experimental curves overlap with each other until pierced point. The maximum major strain calculated by FE analysis was feasible to predict pierced point. To apply nonlinear FE analysis for the porcine ligamentum flavum, the Mooney-Rivlin coefficient of the porcine ligamentum flavum was identified from the tensile test data. Assuming that the sharp bar pierced the ligamentum flavum when the maximum major strain reached a constant value, the required displacement became shorter by 1.0mm by applying the initial tension.

Abstract
INTRODUCTION Genotyping of UGTI1Al could be useful for prediction of severe toxicities for patients treated with irinotecan; however, genotype-based recommended dose (RD) has not been established. The aim of the present study was to determine the RD of irinotecan in combination with cisplatin (CPT-P) for individuals with or without UGT1A1 polymorphisms. MATERIALS AND METHODS According to polymorphisms of UGTIAl*28, *6, and *27, RDs were determined by three-case cohort methods for patients with wild-type and heterotype, and by inter-patient dose escalation for homotype patients. Pharmacokinetic studies were also evaluated. During May 2009 and July 2011, 18 Japanese patients were enrolled; 16 patients with ovarian carcinoma, and two cases with cervical cancer. The RD of irinotecan was determined as 50 mg/m2 for the patients with wild-type, 40 mg/m2 for those with heterotype, and 30 mg/m2 for homotype UGT IAl genotype. RESULTS Patients with homotype UGTIAl1 alleles had a significantly lower glucuronidation ratio in comparison with UGTIAI wild-type and heterotype cases. CONCLUSION UGT1A1 genotype-based RDs of irinotecan in CPT-P therapy were determined. Further studies to investigate efficacy of the RD including response evaluation are needed to confirm the present results.

Abstract
A 57-year-old man presented with mesial inclination of the lower right first molar caused by untreated loss of the second premolar. The occlusal relationship was restored by dental implant treatment following improvement of the intraoral environment by orthodontic therapy. At his initial visit, the interdental spacing in the molar-premolar region was inadequate, as the first molar had mesially inclined into the extraction space of the second premolar. The patient had also lost the second molar and complained of masticatory problems on the right side. It was considered necessary to restore the second molar and improve the occlusal relationship with the first molar to recover occlusal function on the right side. After orthodontic therapy to correct the position of the mesially inclined tooth, occlusal restoration was carried out by dental implant treatment. The patient's clinical condition has remained excellent at over 5 years 2 months post-surgically and the patient is satisfied with the treatment outcome. The combination of dental implant treatment and orthodontic therapy were effective in improving the intraoral environment in this patient, indicating the efficacy of interdisciplinary treatment planning and practice.

Abstract
The cytotoxicity of coal fly ash particles was investigated in rat alveolar macrophages cultured in vitro. Fly ash particles of a similar diameter (1-5 mum) were selected and then separated into five groups with respect to density (i.e. <1.6, 1.6-2.0, 2.0-2.4, 2.4-2.8 and >2.8 g/cm(3)). The exclusion of trypan blue and the extracellular release of lactate dehydrogenase were used as indicators of cell viability. The fraction of fly ash particles with the highest density (>2.8 g/m(3)) was most cytotoxic. The degree of cytotoxicity appeared to be correlated with the amount of particles taken up by macrophages as well as with their heavy metal concentrations. Morphological observation of the surface of the macrophages by scanning electron microscopy revealed a decrease in the number of filopodia and microvilli and an enhancement of the ruffled membrane. These morphological changes became more obvious with increasing concentrations of fly ash particles, but there was no characteristic change specific to each fraction of fly ash.

Abstract
OBJECTIVE To evaluate prognosis of high-grade endometrial cancers, comparing serous (SC) and clear cell (CCC) types to grade 3 endometrioid carcinoma (ECG3). METHODS Among patients with endometrial cancer treated in two decades, medical records of patients with high-grade endometrial cancer were retrospectively investigated. RESULTS Of 447 endometrial cancers, 107 (24%) high-grade endometrial cancers were identified, with the increasing incidence in the last decade (28% vs 19%; p = 0.026). There were 24 SC, 14 CCC and 69 ECG3. Median age was 62, 68, and 61 years, respectively, with the CCC type showing an elder age than the ECG3 type (p = 0.012). The rates of patients with Stage IIIc-IV, lymph node assessment or complete resection at primary surgery, and post-operative chemotherapy were not significantly different; however, response rate to first-line chemotherapy in patients with measurable disease was lower in SC than ECG3 (3 / 11, 27% vs 14 / 19, 74%; p = 0.037), regardless of regimens. Five-year overall survival (OS) was 40%, 71%, and 71% respectively, and five-year progression-free survival (PFS) was 25%, 71%, and 61%, respectively, showing SC with worse prognosis than ECG3 on both OS (p = 0.026) and PFS (p = 0.0028). According to the multivariate analysis, age > or = 70, Stage IIIc-IV and incomplete resection were independent prognostic factors on poor OS, whereas SC, Stage IIIc-IV and incomplete resection were on poor PFS. CONCLUSIONS The increasing trend of high-grade endometrial cancer and different outcomes according to histological subtypes, especially poor PFS and chemotherapeutic response in SC, were suggested.

Abstract
BACKGROUND Malignant transformation of ovarian mature cystic teratoma is rare, and occurs in approximately 1% of all cases. The most common histology arising in mature cystic teratoma is squamous cell carcinoma. Less frequently, malignant transformation is represented by an endocrine tumor. To date, only five cases of large cell neuroendocrine carcinoma (LCNC) arising in a mature cystic teratoma of the ovary have been reported. CLINICAL CASE A 69-year-old woman presented with a 15-cm left ovarian mass, and was diagnosed with Stage IV large cell carcinoma neuroendocrine carcinoma (LCNC) arising in mature cystic teratoma (MCT) of the left ovary. The patient received adjuvant chemotherapy with paclitaxel and carboplatin, however, residual tumors increased in size. Six months after the debulking surgery she succumbed to the disease. A literature review revealed LCNC of the ovary showed excessively aggressive phenotype in malignant transformation from ovarian mature cystic teratoma. CONCLUSION The present case of LCNC arising in MCT had an exceedingly poor prognosis, which was suggested in the previous five cases reported.

Abstract
The normal serum CA125 half-life and distribution of the normal serum nadir CA125 value in patients with epithelial ovarian carcinoma (EOC) have not been determined yet. Among patients with EOC, 41 patients met the inclusion criteria of the present study: the patients that underwent complete cytoreductive surgery and six cycles of platinum-containing chemotherapy, and who had no recurrent disease more than five years. Serum CA125 half-life (T1/2) during primary surgery and primary chemotherapy was calculated and serum nadir CA125 level was evaluated by logarithmic-transformed serum CA125. Median value of nadir CA125 was 7 U/ml (range 3-20 U/ml), and the mean ln (serum nadir CA125) was 1.96 +/- 0.45. Mean T1/2 was 10.4 days in all patients, and T1/2 value was associated with the preoperative serum levels of CA125. Predicted slope of CA125 regression curve was also influenced by the preoperative CA125 value. The present study provides fundamental information with regard to normal half-life time and normal nadir of CA125 in EOC patients.

Abstract
We report on the mapping of quantum-Hall edge states by quasiresonant photovoltage measurements using a near-field scanning optical microscope. We have observed fine structures near sample edges that shift inward with an increase in magnetic field in accordance with the shift of the positions of the quantum-Hall edge states. We have found a transition from the weak disorder regime where compressible-incompressble strips are visible to the strong disorder regime where fluctuations smear out incompressible strips.

Abstract
PATIENT A 67-year-old female with root fracture of the maxillary central incisor underwent implant placement immediately after extraction, with the goal of shortening the treatment period. The superstructure was placed on the implant after a 4-month healing period. Review 5 years after implant loading revealed no clinical problems. DISCUSSION AND CONCLUSION The treatment time was shortened effectively by the flapless immediate post-extraction placement procedure. Immediate post-extraction implant placement based on proper examination and diagnosis would reduce the patient burden.

Abstract
ABSTRACTSelf-organization processes in Xe nanocrystals embedded in Al are observed with in-situ high-resolution electron microscopy. Under electron irradiation, stacking fault type defects are produced in Xe nanocrystals. The defects recover in a layer by layer manner. Detailed analysis of the video reveals that the displacement of Xe atoms in the stacking fault was rather small for the Xe atoms at boundary between Xe and Al, suggesting the possibility of the stacking fault in Xe precipitate originating inside of precipitate, not at the Al/Xe interface.

Abstract
Measles is an acute exanthema spread by airborne infection and still occurs sporadically in Japan. Its mortality rate is estimated to be 0.1% and it has no specific therapy. Here, we present two cases of measles in pregnant women immediately preceding delivery. It is required to prevent the perinatal spread of measles when pregnant women are infected immediately preceding delivery. We measured the measles antibody titer of 1,393 pregnant women by enzyme immunoassay between 2004 and 2008. The antibody-positive rate was 87.7%, but the antibody titer tended to be low in childbearing age. Preventive treatment with measles vaccination is extremely important before pregnancy in order to prevent perinatal measles.

Abstract
BACKGROUND The present study observed effects of the histamine H(4) receptor on chronic allergic contact dermatitis induced by repeated challenge in mice. METHODS Acute contact dermatitis was induced by single epicutaneous challenge of 2,4,6-trinitro-1-chlorobenzene (TNCB) to the ear. Chronic allergic contact dermatitis was developed by repeated epicutaneous challenge using TNCB on the dorsal back skin. H(4) receptor antagonist JNJ7777120 was administered to wild-type mice, while H(4) receptor agonist 4-methylhistamine was administered to histidine decarboxylase (HDC) (-/-) mice that synthesized no histamine. RESULTS HDC (-/-) mice did not differ phenotypically from HDC (+/+) mice, and H(4) receptor antagonist/agonist did not have clinical effects in terms of acute contact dermatitis reactions. H(4) receptor antagonist ameliorated skin eczematous lesions induced by repeated TNCB challenge in HDC (+/+) mice. On the contrary, H(4) receptor agonist exacerbated skin lesions exclusively in HDC (-/-) mice. Application of H(4) receptor agonist induced migration of mast cells and eosinophils in skin lesions, and H(4) receptor antagonist suppressed these changes. H(4) receptor was immunohistochemically detected on mast cells in eczematous lesions. Levels of interleukin (IL)-4, -5, and -6 in lesions were decreased, whereas levels of interferon-gamma and IL-12 were increased by H(4) receptor antagonistic activity. Serum Immunoglobulin E levels rapidly increased with repeated challenge, but decreased with H(4) receptor antagonist. CONCLUSION Because chronic allergic contact dermatitis is developed by H(4) receptor stimulation, H(4) receptor antagonists might represent new candidate drugs for treating chronic allergic contact dermatitis.

Abstract
A sensitive nanosized molybdenum oxide (MoO(x)) photodetector is manufactured at a desired position by electron-beam-induced deposition (EBID). As-deposited MoO(x) had a conductivity approximately 300 S cm(-1). After 2 h annealing at 573 K, the conductivity of nanowires decreased 10 times to approximately 30 S cm(-1) and MoO(x) had photoconductivity. Nanosized MoO(x) wires enhanced the sensitivity of optical devices due to an increased surface area to volume ratio.

Abstract
Nanoisland films prepared by annealing thin gold films at high temperatures were imaged using scanning electron microscopy (SEM) and atomic force microscopy, and optically characterized through absorption spectroscopy. Thin gold films of effective thicknesses 2, 5 and 7 nm annealed at 500, 700 and 900 degrees C were fabricated and studied experimentally. The measured absorption characteristics in support of theoretical calculations showed that the shapes of gold islands were partial spheres. The position of the peak absorption wavelength measured with s-polarized light or at normal incidence confirmed that the island shape grew from a near-hemisphere towards a sphere with increasing annealing temperature. The SEM images confirmed that the size of islands increased from 15 nm in diameter to 40 nm in diameter as film thickness increased from 2 to 5 nm. The affect of the index of the substrate material on absorption characteristics were also studied by comparing the absorption spectra of gold island films on quartz and LaSF15 glass substrates. The use of gold nanoisland films for preparing localized surface plasmon resonance substrates was suggested as they held advantages over the gold colloid films.

Abstract
The most common neoplasms of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma (CCC) is mostly derived from the ovary and often associated with endometriosis. We describe the clinicopathologic features of two cases diagnosed as CCC of the peritoneum origin. Case 1, a 53-year-old woman, presented with upper abdominal and pelvic tumors. Case 2, a 66-year-old woman, presented with massive ascites and abdominal tumor. The ovaries and uterine endometrium of these cases were not affected, and the tumors were diagnosed as Stage IIIc CCC of the peritoneum origin. Pathologically, endometriosis was not observed in either case. Adjuvant chemotherapy using irinotecan and cisplatin was effective in one case. The cases and a review of the literature suggested that residual tumor volume size determines the survival of these patients, and that the tumors show resistance to conventional platinum-based chemotherapy.

Abstract
Measurements of thickness using electron energy loss spectroscopy (EELS) are revised. Absolute thickness values can be quickly and accurately determined with the Kramers-Kronig sum method. The EELS data analysis is even much easier with the log-ratio method, however, absolute calibration of this method requires knowledge of the mean free path of inelastic electron scattering lambda. The latter has been measured here in a wide range of solids and a scaling law lambda approximately rho(-0.3) versus mass density rho has been revealed. EELS measurements critically depend on the excitation and collection angles. This dependence has been studied experimentally and theoretically and an efficient model has been formulated.
