Abstract
Methodical screening of safe and efficient drug candidate compounds is crucial for drug development. A high-throughput and accurate compound evaluation method targeting the central nervous system can be developed using in vitro neural networks. In particular, an evaluation system based on a human-derived neural network that can act as an alternative to animal experiments is desirable to avoid interspecific differences. A microelectrode array (MEA) is one such evaluation system, and can measure in vitro neural activity; however, studies on compound evaluation criteria and in vitro to in vivo extrapolation are scarce. In this study, we identified the parameters that can eliminate the effects of solvents from neural activity data obtained using MEA allow for accurate compound evaluation. Additionally, we resolved the issue associated with compound evaluation criteria during MEA using principal component analysis by considering the neuronal activity exceeding standard deviation (SD) of the solvent as indicator of seizurogenic potential. Overall, 10 seizurogenic compounds and three negative controls were assessed using MEA-based co-cultured human-induced pluripotent stem cell-derived neurons and astrocytes, and primary rat cortical neurons. In addition, we determined rat cerebrospinal fluid (CSF) concentrations during tremor and convulsion in response to exposure to test compounds. To characterize the in vitro to in vivo extrapolation and species differences, we compared the concentrations at which neuronal activity exceeding the SD range of the solvent was detectable using the MEA system and rat CSF concentration.

Abstract
OBJECTIVES Recently, the standard of care for advanced urothelial cancer (UC) has been changed by developing immune-checkpoint inhibitors (ICIs). However, its response rate is limited to 20-30%. The identification of biomarkers to predict the therapeutic effects of ICIs is urgently needed. The present study explored the association between immunohistochemical biomarkers and clinical outcomes in UC patients treated with pembrolizumab. PATIENTS AND METHODS A total of 85 patients with UC who received pembrolizumab after chemotherapy from January 2018 to May 2020 were retrospectively reviewed. Tumor tissues were obtained for immunohistochemical study from 47 out of 85 patients. The protein expressions of PD-L1, WT1, Nectin-4, CD4, CD8, Foxp3, and CD68 in tumor cells and/or tumor infiltrating lymphocytes were immunohistochemically examined. The associations between protein expressions and overall survival (OS), progression-free survival (PFS), and disease control rate (DCR) were statistically analyzed. RESULTS Patients with positive PD-L1 in tumor cells showed significantly worse OS (Log-rank test: HR 5.146, p = 0.001, Cox regression analysis: HR 4.331, p = 0.014) and PFS (Log-rank test: HR 3.31. p = 0.022), along with significantly lower DCR (14.3%) compared to the PD-L1 negative patients (67.5%). In addition, patients with strong expression of Nectin-4 in tumor cells showed significantly higher DCR (100%) than the other patients (50%). CONCLUSION PD-L1 expression in tumor cells was associated with poor prognosis (OS and PFS) and low DCR. Interestingly, the strong expression of Nectin-4 was correlated with high DCR. PD-L1 and Nectin-4 expression in tumor cells could be prognostic biomarkers useful for pembrolizumab in patients with advanced UC.

Abstract
In vitro microelectrode array (MEA) assessment using human induced pluripotent stem cell (iPSC)-derived neurons holds promise as a method of seizure and toxicity evaluation. However, there are still issues surrounding the analysis methods used to predict seizure and toxicity liability as well as drug mechanisms of action. In the present study, we developed an artificial intelligence (AI) capable of predicting the seizure liability of drugs and identifying drugs using deep learning based on raster plots of neural network activity. The seizure liability prediction AI had a prediction accuracy of 98.4% for the drugs used to train it, classifying them correctly based on their responses as either seizure-causing compounds or seizure-free compounds. The AI also made concentration-dependent judgments of the seizure liability of drugs that it was not trained on. In addition, the drug identification AI implemented using the leave-one-sample-out scheme could distinguish among 13 seizure-causing compounds as well as seizure-free compound responses, with a mean accuracy of 99.9 ± 0.1% for all drugs. These AI prediction models are able to identify seizure liability concentration-dependence, rank the level of seizure liability based on the seizure liability probability, and identify the mechanism of the action of compounds. This holds promise for the future of in vitro MEA assessment as a powerful, high-accuracy new seizure liability prediction method.

Abstract
Screening for drug discovery targeting the central nervous system requires the establishment of efficient and highly accurate toxicity test methods that can reduce costs and time while maintaining high throughput using the function of an in vitro neural network. In particular, an evaluation system using a human-derived neural network is desirable in terms of species difference. Despite the attention the microelectrode array (MEA) is attracting among the evaluation systems that can measure in vitro neural activity, an effective analysis method for evaluation of toxicity and mechanism of action has not yet been established. Here we established analytical parameters and multivariate analysis method capable of detecting seizure liability of drugs using MEA measurement of human iPS cell-derived neurons. Using the spike time series data of all drugs, we established periodicity as a new analytical parameter. Periodicity has facilitated the detection of responses to seizurogenic drugs, previously difficult to detect with conventional analytical parameters. By constructing a multivariate analytical method that identifies a parameter set that achieves an arbitrary condition, we found that the parameter set comprising total spikes, maximum frequency, inter maximum frequency interval, coefficient of variance of inter maximum frequency interval, and periodicity can uniformly detect the seizure liability of seizurogenic drugs with different mechanisms of action. Seizurogenic drugs were suggested to increase the regularity of the network burst in MEA measurements in human iPS cell-derived neurons.

Introduction
Improvements in cardiovascular imaging have contributed to the accurate diagnosis and treatment of cardiovascular diseases. In recent years, we can find a new demand from surgical departments, i.e., 3D heart models of patients for preoperative simulations. However, a 3D surgical model needs a detailed segmentation of heart structures from clinical images because these details are essential for achieving accurate polygon data of an exact 3D model. Thus, in most cases, manual segmentation is required for complicated heart shapes such as the chamber wall, valves, and papillary muscles, which causes a prolonged duration time.
Purpose
We aim to achieve an automated heart segmentation using a convolutional neural network (CNN) trained using deep learning techniques for the rapid creation of 3D surgical heart models of individual patients.
Methods
We constructed our original CNN program based on the latest artificial intelligence techniques and trained it to extract shapes of the heart from cardiac computed tomography (CT) images. The training data was 361 slices selected from CT scans of 10 patients. We used data augmentation to increase the amount and diversity of the data into 24,052 slices. The training result with the best Intersection over Union (IoU), one of the evaluation metrics used in deep learning, was saved. Finally, we used the best-trained CNN to construct 3D polygon data of two surgical cases of hypertrophic obstructive cardiomyopathy (HOCM) for preoperative assessments.
Results
The IoU attained 0.85 after deep learning. The time required to complete the 3D polygon data for the first HOCM case was 5 minutes for segmentation by the trained CNN and 3 hours for data correction by a human operator. Similarly, the time required for the second case was 5 minutes for segmentation without manual correction. We had to correct the segmentation for the first case because we needed an exact 3D model for the preoperative assessment (Fig. 1). According to our records of the other eight 3D heart models in the lab, the work for a 3D polygon shape from CT images needs a median 30 hours (quartiles 23-50 hours) when the procedure is fully manual and non-continuous with breaks in between.
Conclusion
The CNN-based segmentation aided the constructing heart shapes from cardiac CT images of preoperative patients. Although the performance, reaching IoU of 0.85, was insufficient for fully automatic segmentation, the methodology can shorten the process duration from several hours to several minutes for detailed segmentation of heart structures.
We previously applied the CNN-based segmentation to the aorta, aortic stenosis valves, and atheromatous plaque in clinical images, demonstrating adequate segmentation performance. The proposed methodology can be applied as a fundamental technology of cardiovascular imaging for obtaining the actual structures of a target object as 3D coordinate values or a 3D model within a reasonable duration time.

Abstract
e15661 Background: 5 years of survival rate of stage IV cancer patients have kept poor for these 30 years. This is mainly due to inevitability of anti-cancer drugs for them because of multi-organ metastasis. We developed a novel CTC technique to identify CTCs responsible for metastasis, and provided a method to kill those dangerous cells by Iodine therapy. Methods: We did 314 CTC tests, and 53 patients received it more than twice (average prognosis of 4.5 months). Our CTC tests by flouring 4cc blood of the patients into a special device with > 50,000 pores of 8μ diameters, this device can only catch CTCs. We also stained with cytokeratin and vimentin anti-bodies (see table). Iodine water was made of 10,000 ppm of NaI with certain numbers of additional chemicals. This preclinical trial was accepted by our ethical committee. Results: We developed a novel CTC technique to catch 95% of CTCs and identified 3 types of CTCs (see table). Without any therapy, type 1 cells disappeared, while all patients with type 2 cells died within a couple of months, this may be due to EMT (epithelial mesenchymal transformation) on them. We tested certain numbers of ant-cancer drugs and found that no drugs can kill type 2 cells, only stable Iodine water provided by our clinic can kill type 2 cells perfectly within two months, and 51 out of 53, the terminal stage of patients can survive more than a year. Conclusions: Novel CTC test can identify 3 types of CTCs and type 2 cells can be responsible for the poor survival of terminal stage cancer patients because they are responsible for metastasis, and anti-cancer drugs cannot kill them. It has been well-known that Iodine induces PPARγ which can promote apoptosis of type 2 cells and inhibit EMT. Iodine may improve their poor prognosis.[Table: see text]

Abstract
AIMS Given the significance of Salmonella enterica in both human and animal health, and a recent global dissemination of Salmonella 4,[5],12:i:-, changes in the prevalent serovars and antimicrobial resistance in clinical isolates of Salmonella from cattle and pigs were investigated in Japan. METHODS AND RESULTS The serovars and antimicrobial susceptibilities of 1605 Salmonella enterica isolated from cattle (n = 894) and swine (n = 711) between 2002 and 2016 were examined. The most common serovar among all samples was Salmonella Typhimurium. However, its monophasic variant with antigenic structure S. 4,[5],12:i:-, which was first detected in cattle in 2006 and swine in 2010, has been rapidly increasing in incidence and resistance. Resistance rates to cefotaxime and ciprofloxacin were generally low (<10% in the cattle isolates and <5% in the swine isolates); however, isolates resistant to more than five antimicrobials, which often include these antimicrobials, were recently detected in Salmonella Dublin, S. 4,[5],12:i:-, S. Typhimurium, Salmonella Newport, Salmonella Choleraesuis and Salmonella 6,7:c:-. Among them, two S. 4,[5],12:i:- isolates possessed extended-spectrum β-lactamase-encoding genes; blaSHV-12 or blaCTX-M-55 , respectively, while all the five S. Typhimurium isolates possessed AmpC-type β-lactamase gene of blaCMY-2 . CONCLUSIONS S. 4,[5],12:i:- has been rapidly increasing and exhibiting a remarkable change in antimicrobial resistance in Japan. Considering certain serovars are characterized by multidrug resistance including medically important antimicrobials, continuous monitoring and appropriate measures are required to protect public health and veterinary husbandry. SIGNIFICANCE AND IMPACT OF THE STUDY This study presents a trend in the serovars and antimicrobial resistance in clinical isolates of Salmonella from cattle and pigs in Japan, and showed that there were certain types of Salmonella serovars depending on the animal origin which needs more attention.

Abstract
Somatosensory information from the dental pulp is processed in the primary (S1) and secondary somatosensory cortex (S2) and in the insular oral region (IOR). Stimulation of maxillary incisor and molar initially induces excitation in S2/IOR, rostrodorsal to the mandibular incisor and molar pulp-responding regions. Although S1 and S2/IOR play their own roles in nociceptive information processing, the anatomical and physiological differences in the temporal activation kinetics, dependency on stimulation intensity, and additive or summative effects of simultaneous pulpal stimulation are still unknown. This information contributes not only to understanding topographical organization but also to speculating about the roles of S1 and S2/IOR in clinical aspects of pain regulation. In vivo optical imaging enables investigation of the spatiotemporal profiles of cortical excitation with high resolution. We determined the distinct features of optical responses to nociceptive stimulation of dental pulps between S1 and S2/IOR. In comparison to S1, optical signals in S2/IOR showed a larger amplitude with a shorter rise time and a longer decay time responding to maxillary molar pulp stimulation. The latency of excitation in S2/IOR was shorter than in S1. S2/IOR exhibited a lower threshold to evoke optical responses than S1, and the peak amplitude was larger in S2/IOR than in S1. Unexpectedly, the topography of S1 that responded to maxillary and mandibular incisor and molar pulps overlapped with the most ventral sites in S1 that was densely stained with cytochrome oxidase. An additive effect was observed in both S1 and S2/IOR after simultaneous stimulation of bilateral maxillary molar pulps but not after contralateral maxillary and mandibular molar pulp stimulation. These findings suggest that S2/IOR is more sensitive for detecting dental pulp sensation and codes stimulation intensity more precisely than S1. In addition, contra- and ipsilateral dental pulp nociception converges onto spatially closed sites in S1 and S2/IOR.

Abstract
OBJECTIVE Mesiodentes are usually found in the central position of the upper or lower jaw as supernumerary teeth. Here, we obtained 10 mesiodentes and three permanent teeth (PT) and separated the dental pulp (DP) from these into crown and root portions. We then characterized and compared the isolated crown portion-derived cells (crown cells) with root portion-derived cells (root cells) using a range of in vitro assays. MATERIALS AND METHODS Crown cells and root cells were examined for cell surface marker expression, colony-forming unit-fibroblast (CFU-F), cell proliferation, cell cycle characteristics and markers, and osteogenic and adipogenic differentiation. RESULTS The proportion of CD105-positive cells (CD105(+) cells) in the crown cells vs the root cells varied among the mesiodentes, but not among the PT. When there were more CD105(+) cells in the root cells than in the crown cells, the root cells showed higher CFU-F, proliferation capacity, and osteogenic differentiation capacity. In contrast, when the crown cells contained more CD105(+) cells than the root cells, the crown cells showed the higher CFU-F, proliferation capacity, and osteogenic differentiation capacity. In addition, the sorted CD105(+) cells showed higher CFU-F and proliferation capacity than the sorted CD105(-) cells. CONCLUSION These results indicated that proportion of CD105(+) cells is an effective means of characterizing DP-derived cells in mesiodentes.

Abstract
Among four ethnic groups in a lowland area of Nepal, the prevalences of abnormal haemoglobin, thalassaemia, glucose-6-phosphate-dehydrogenase (G6PD) deficiency, hereditary South-east Asian ovalocytosis (SAO) and Duffy blood-group antigen Fy/Fy were determined and related to each group's habitat. The group that has lived for many decades in a malaria-endemic lowland area, the Danuwar, was found to have a high prevalence of alpha+-thalassaemia (79.4%) and low prevalences of haemoglobin E and G6PD deficiency. Much lower prevalences of alpha+-thalassaemia were observed in the Newar (20.5%), Parbate (16.5%) and Tamang (8.8%), who, until the 1950s, all spent their hot-season nights in malaria-free areas at higher altitudes. No subjects with any other identified abnormal haemoglobin, beta-thalassaemia, SAO or Fy/Fy were detected.

Abstract
AbstractIntroduction:Little has been reported regarding the minimum conditions, information, and knowledge essential for dispatching nurses to join in sudden-onset disaster events from the viewpoint of nurses. This paper explores the issues and concerns that nurses faced when asked to respond to the 1995 Great Hanshin-Awaji Earthquake event in Japan.Methods:A standardized written survey tool was developed using input from four nurses who had responded to the disaster event. Questionnaires that included both “yes” and “no” answers and multiple-choice answers were developed and sent to 823 nurses who worked in four hospitals.Results:A total of 477/823(58.0%) questionnaires were completed and returned. Of the respondents to the questionnaire, 309 (62.1%) were qualified nurses, and 148 (37.9%) were students. Sixty-nine (15%) of the total 477 respondents participated in the disaster response to the Great Hanshin-Awaji Earthquake. Primary among respondents' concerns were that they should wait for their superiors or institutions to direct them to go “somewhere” and to do “something” and how far away from home would they be required to travel. Home responsibilities conflicting with disaster response were a common concern for respondents.Conclusion:Managers should consider including the following conditions in disaster dispatch plans: (1) the dispatches should be made part of nursing duties; (2) the disaster plan should be constructed with organizations near disaster sites; and (3) clear directions regarding destination and expected activities should be provided to nurses.

Abstract
OBJECTIVE In general, no consensus has been reached regarding the diagnostic criteria for obstructive sleep apnoea syndrome (OSAS) in children and the criteria for selecting treatment are inconsistent. Therefore, the craniofacial and pharyngeal airway morphology of OSAS in children who had undergone drug therapy (non-op group) and OSAS in children who had undergone both drug therapy and surgical therapy (adenotonsillectomy) (op group) were compared. The purpose of this study was to examine the effectiveness of craniofacial morphology and pharyngeal airway morphology analysis in the treatment of children with OSAS. METHODS The craniofacial and pharyngeal airway morphology of the control group, the non-op group and the op group were compared to examine the differences of each group. The comparison used Mann-Whitney's U test. RESULTS A comparison between the non-op and the op groups showed significant differences in the facial axis, mandibular plane angle, ramus plane to the SN (porion and orbit) point, point Pog (pogonion) to the McNamara line, anteroposterior dysplasia indicator (APDI), D-AD1 [the distance between the posterior nasal spine (PNS) point and the nearest adenoid tissue, measured along the PNS-Ba (basion) point plane], D-AD2 (the distance between the PNS point and the nearest adenoid tissue, measured along a line from the PNS point perpendicular to the S (sella turcica)-Ba point plane), upper pharynx and soft palatal length. The op group showed significantly lower values of APDI than the non-op group, indicating that the op group showed a significant occlusion of class II, and that the mandibular bone was positioned posteriorly relative to the maxillary bone. CONCLUSIONS The op group showed a significant posterior position and backward rotation of the mandibular bone, stenosis of the nasopharyngeal airway and an elongated soft palate compared with the non-op group, and it was speculated that there was a high probability of the necessity of surgical therapy (adenotonsillectomy) when a morphological factor played a major role as a cause of obstructive sleep apnoea. We recommend craniofacial morphology analysis and pharyngeal airway morphology analysis in the diagnosis and treatment planning of OSAS children.

Abstract
Carrier cells delivering a conditionally replicating adenovirus (CRAd), which selectively replicates in tumor cells and induces tumor cell lysis, have promising potential for treatment of cancer because CRAd-loaded carrier cells evade inhibition by neutralizing anti-adenovirus (Ad) antibodies and because the carrier cells are locally retained at the injection point after local injection. A previous study by Hamada et al. demonstrated that carrier cells (CRAd-containing cell fragments derived from the carrier cells) are engulfed into the target cells, probably through a pathway independent of the primary receptor for Ad, the coxsackievirus and Ad receptor (CAR) (Mol Ther, 15: 1121-1128; 2007); however, it remains to be elucidated whether carrier cells infected with a conventional CRAd, which is composed of subgroup-C Ad serotype-5 (Ad5), mediate antitumor effects on CAR-negative cells. In order to examine whether carrier cells delivering a conventional CRAd (Carrier-F5) induce lysis of CAR-negative tumor cells, CAR-positive and CAR-negative tumor cells were incubated with Carrier-F5. Carrier-F5 mediated efficient killing of CAR-positive tumor cells; however, CAR-negative tumor cells were almost refractory to Carrier-F5. On the other hand, carrier cells loaded with a fiber-substituted CRAd containing fiber proteins of Ad serotype-35 (Ad35) (CRAd-F35), which binds to human CD46 for infection, showed efficient killing of both CAR-positive and CAR-negative tumor cells. Intra-tumoral injection of carrier cells loaded with CRAd-F35 (Carrier-F35) also resulted in efficient regression of both CAR-positive and CAR-negative tumors. These results demonstrated that the expression levels of receptors for Ad are an important factor for CRAd-loaded carrier cell-mediated cancer therapy, and that Carrier-F35 would have potential as a cancer treatment for not only CAR-positive tumors but also CAR-negative tumors.

Abstract
We investigated the correlation between fecal bacteria composition in early infancy and the prevalence of allergic diseases in late infancy. The fecal microbiota in the first 2 months was profiled using the 16S rRNA V6 short-tag sequences in the community and statistically compared between two groups of subjects who did and did not show allergic symptoms in the first 2 years (n = 11 vs. 11). In the allergic group, genus Bacteroides at 1 month and genera Propionibacterium and Klebsiella at 2 months were more abundant, and genera Acinetobacter and Clostridium at 1 month were less abundant than in the nonallergic group. Allergic infants who showed high colonization of Bacteroides and/or Klebsiella showed less colonization of Clostridium perfringens/butyricum, suggesting antagonism between these bacterial groups in the gastrointestinal tract. It was also remarkable that the relative abundance of total Proteobacteria, excluding genus Klebsiella, was significantly lower in the allergic than in the nonallergic group at the age of 1 month. These results indicate that pyrosequence-based 16S rRNA gene profiling is valid to find the intestinal microbiotal disorder that correlates with allergy development in later life.

Abstract
OBJECTIVE Injection of complete Freund's adjuvant (CFA) into the temporomandibular joint (TMJ) causes acute swelling around the joint and subsequent morphological alterations in the condyle. We aimed to evaluate changes in the three-dimensional architecture of the condyle induced with CFA. MATERIALS AND METHODS The CFA was injected into the unilateral TMJ of rats and morphological changes in the condyle were assessed repeatedly for 14 days by in vivo micro-CT. RESULTS Osseous abnormalities of condyle were first observed at 3-5 days after CFA injection on the tomographic images, and the condylar deformation became more obvious thereafter. Among 12 condyles examined at 14 days postinjection, osteophytosis was observed in all of the specimens and bone erosion coexisted in five condyles. None of the saline-treated condyles showed architectural changes. Significant changes were detected in the mesiolateral and rostrocaudal widths of the CFA-treated condyles at 10-14 days postinjection (P < 0.01). The extent of both condylar bone formation and resorption was greater in the CFA-injected TMJs than in saline-injected TMJs (P < 0.05). CONCLUSION These results indicate that CFA causes dynamic morphological changes in the condyle and that our experimental approach will provide new insights into the subacute inflammatory processes in the TMJ.

Abstract
Identification of mutations in G6PD gene is performed as an epidemiologic investigation of G6PD deficiency in many countries. In order to understand the hereditary background of G6PD deficiency in a population, screening of mutations is required not only in exonic regions but also for intron and promoter regions. One hundred male neonatal samples diagnosed as with G6PD deficiency by newborn screening in Singapore were used in this study. The multiplex PCR using the multiple tandem forward primers and common reverse primer (MPTP) method was carried out to detect the common 11 mutations in south-east Asia such as Gaohe 95A>G, Orissa 131C>G, Vanua-Lava 383T>C, Mahidol 487G>A, Mediterranean 563C>T, Coimbra 592C>T, Viangchan 871G>A, Chatham 1003G>A, Union 1360C>T, Canton 1376G>T and Kaiping 1388G>A. Samples whose mutations were unidentified by MPTP method were scanned at cording region, intron and promoter region by direct sequencing.Out of 100 samples, 90 samples (90.0%) were identified with one of the above mentioned common mutations. Eight out of 10 samples whose mutations were unidentified by MPTP method carried exonic mutations which had been previously reported such as Murcia 209A>G, Quing Yuan 392G>T, Nankang 517T>C, Chinese5 1024C>T. Two novel mutations were identified in these samples: one had a novel mutation (25C>T); the remaining sample carried a 49 bp deletion in intron 12.

Abstract
OBJECTIVES Our aim was to investigate the diagnostic accuracy of in vivo micro-CT for osseous abnormalities of the rat temporomandibular joint (TMJ) condyle, using macroscopic observations as the "gold standard". METHODS A 30 TMJ arthritis model was prepared by injecting inflammatory complete Freund's adjuvant (CFA) into one side of the TMJ cavities of rats. The TMJ condyles were then imaged using micro-CT. The samples were macroscopically evaluated for osseous abnormalities, including erosions, osteophytes, flattening and concavity. The micro-CT images were independently assessed for abnormalities using the same criteria. Images in three planes were produced using the micro-XYZ technique with the micro-CT equipment. RESULTS According to the macroscopic observations, 26 of the 60 rat condyles showed osseous abnormalities. The micro-XYZ images detected abnormalities in 25 of the condyles. The condyle diagnostic accuracy of micro-CT was 0.98, the sensitivity was 0.96 and the specificity was 1.0. CONCLUSIONS Good diagnostic results were obtained using micro-CT. It is therefore an effective technique for the evaluation of osseous abnormalities in the rat TMJ condyle.

Abstract
BACKGROUND The most common type of pollinosis in Japan is Japanese cedar pollinosis (JCP). While forest walking is a common form of recreation for Japanese people, it has been unclear whether forest walkers with JCP still choose to visit forested areas during the pollen season or whether they avoid those areas, and as such, the aim of this study was to investigate this question. METHODS The study participants were all healthy men and women volunteers aged 20 years or over who visited the Tokyo University Forest in Chiba during 4 different days. The survey was conducted using self-administered questionnaires. RESULTS The number of available responses was 498. Of these, 112 participants who experienced JCP were included in the analysis. Seventy-three participants (65.2%) responded that they visit forests even during the pollen season. The association between forest walking choices during the pollen season and self-rated levels of pollinosis symptoms was not statistically significant (Cramer's V = 0.13, p = 0.47). As many as 60% of the participants who reported serious symptom levels responded that they visit forested areas even during the pollen season. CONCLUSIONS These results revealed that two thirds of forest walkers who had experienced JCP visited forests even during the pollen season. This indicates the further need for public service announcements informing people with JCP that the risk of pollen exposure and subsequent JCP reaction is increased by visiting forested areas during the pollen season.

Abstract
The aim of this study was to evaluate the effect of underwear made of ethylene vinyl alcohol (EVOH) fiber in children with atopic dermatitis (AD). Twenty-one AD children (11 EVOH group and 10 control group) were studied for 4 weeks. Their AD severity based on the Scoring Atopic Dermatitis (SCORAD) score and physiological functions were assessed. The objective SCORAD significantly decreased in both groups. However, the SCORAD score (P<0.01) and urinary cortisol levels (P<0.05) were decreased only in EVOH group. It was concluded that EVOH fiber underwear might be useful for children with atopic dermatitis.

Abstract
The influence of antibiotic exposure in the early postnatal period on the development of intestinal microbiota was monitored in 26 infants including five antibiotic-treated (AT) subjects orally administered a broad-spectrum antibiotic for the first 4 days of life and three caesarean-delivered (CD) subjects whose mothers were intravenously injected by the similar type of antibiotics in the same period. The faecal bacterial composition was analysed daily for the first 5 days and monthly for the first 2 months. Terminal restriction fragment length polymorphisms in the AT subjects showed less diversity with the attenuation of the colonization of some bacterial groups, especially in Bifidobacterium and unusual colonization of Enterococcus in the first week than the control antibiotic-free infants (AF, n=18). Quantitative real-time PCR showed overgrowth of enterococci (day 3, P=0.01; day 5, P=0.003; month 1, P=0.01) and arrested growth of Bifidobacterium (day 3, P=0.03) in the AT group. Furthermore, after 1 month, the Enterobacteriaceae population was markedly higher in the AT group than in the AF group (month 1, P=0.02; month 2, P=0.02). CD infants sustained similar, although relatively weaker, alteration in the developing microbiota. These results indicate that antibiotic exposure at the beginning of life greatly influences the development of neonatal intestinal microbiota.

Abstract
In order to identify a novel candidate gene in systemic lupus erythematosus (SLE), we analysed a panel of six genes encoding molecules involved in the type I interferon (IFN) system. We first identified variants in the five genes related to type I IFN pathway by sequencing. Genotyping of a panel of eight selected single-nucleotide polymorphisms (SNPs) in six candidate genes ( TLR9, MYD88, IRF3, IRF7, IFNB1, IFNA17) was performed in 137 patients with SLE and matched with 152 healthy controls using polymerase chain reaction-restriction fragment length polymorphism analysis. In functional assay, quantitative real-time polymerase chain reaction was performed to assess constitutive IRF3 mRNA expression in peripheral blood mononuclear cells from healthy subjects with different IRF3 promoter haplotypes. Among eight SNPs genotyped, an IRF3 SNP at –925 was found to be associated with SLE after correction for multiple tests (corrected P = 0.016). Of total five IRF3 SNPs genotyped, the promoter IRF3 SNPs –925A/G and –776C/T showed the most significant association with SLE. With regard to –925A/G, the frequency of GG genotype was significantly decreased among SLE patients compared with the control group (1.5% vs. 9.9%; χ2 = 10.0, P = 0.0015, odds ratio 0.12, 95% confidence interval 0.027–0.554). Our experimental data indicated that constitutive IRF3 mRNA expression was significantly lower in cells carrying the minor G-T/G-T haplotype pair compared with those carrying the major A-C haplotype. In conclusion, we showed that the promoter SNPs of the IRF3 gene were significantly associated with resistance against SLE.

Abstract
CARD15 was first identified as a susceptibility gene for Crohn's disease. More recently, CARD15 mutations were shown to be associated with the pediatric granulomatous inflammatory diseases, Blau syndrome and early-onset sarcoidosis (EOS). The aim of the present study was to evaluate whether CARD15 variants also play a role in patients with ordinary sarcoidosis other than EOS. We enrolled 135 Japanese sarcoidosis patients with uveitis as well as 95 healthy individuals and performed mutation analysis by direct sequencing of CARD15 exon 4. Direct DNA sequencing in the sarcoidosis patients showed eight CARD15 variants, including five novel mutations (13402C>T, 13543C>T, 13775C>A, 13937G>A, and 14079C>T). Compared with healthy individuals, CARD15 mutations are not common in the Japanese patients with sarcoidosis. Based on the results, we examined the clinical manifestations in patients with sarcoidosis according to their CARD15 mutations. Sarcoidosis patients with these mutations have no specific clinical features with regard to course of the disease or disease severity. Our results indicate that in general, CARD15 mutations may not contribute to the risk of sarcoidosis.

Abstract
There is little information on the molecular mechanisms in FK506-mediated neuroprotection. In the present study, we investigated the protective effect of FK506, an immunosuppressant and neuroprotectant, on trimethyltin (TMT)-induced neurotoxicity in the rat hippocampus. Histologically, TMT-induced neuronal damage was partially prevented by FK506 in the hippocampal CA1 region, but not in CA3. FK506 treatment significantly reduced the number of apoptotic cells in CA1, but not in CA3, and also prevented induction of cognitive deficits by TMT. Microarray analysis of the rat hippocampus detected 14 genes with TMT-induced alteration of mRNA expression that was rescued by FK506 treatment. Subsequent quantitative RT-PCR analysis confirmed elevated mRNA levels for four inflammatory genes, glutathione S-transferase, lysozyme, matrix Gla protein, and osteopontin after TMT treatment. Upregulation of these genes was reversed by FK506 treatment at 5 days postgavage. Immunohistochemistry revealed that FK506 reduced osteopontin (OPN) induction by TMT in the periarterial area at 5 days postgavage. Our data suggest that inflammatory gene expression is involved in TMT-induced damage to the hippocampal CA1 region, resulting in apoptosis, and that this process is initiated by periarterial OPN activation, and can be alleviated by FK506.
