Abstract
Although oxytocin may provide a novel therapeutics for the core features of autism spectrum disorder (ASD), previous results regarding the efficacy of repeated or higher dose oxytocin are controversial, and the underlying mechanisms remain unclear. The current study is aimed to clarify whether repeated oxytocin alter plasma cytokine levels in relation to clinical changes of autism social core feature. Here we analyzed cytokine concentrations using comprehensive proteomics of plasmas of 207 adult males with high-functioning ASD collected from two independent multi-center large-scale randomized controlled trials (RCTs): Testing effects of 4-week intranasal administrations of TTA-121 (A novel oxytocin spray with enhanced bioavailability: 3U, 6U, 10U, or 20U/day) and placebo in the crossover discovery RCT; 48U/day Syntocinon or placebo in the parallel-group verification RCT. Among the successfully quantified 17 cytokines, 4 weeks TTA-121 6U (the peak dose for clinical effects) significantly elevated IL-7 (9.74, 95 % confidence interval [CI] 3.59 to 15.90, False discovery rate corrected P (PFDR) < 0.001), IL-9 (56.64, 20.46 to 92.82, PFDR < 0.001) and MIP-1b (18.27, 4.96 to 31.57, PFDR < 0.001) compared with placebo. Inverted U-shape dose-response relationships peaking at TTA-121 6U were consistently observed for all these cytokines (IL-7: P < 0.001; IL-9: P < 0.001; MIP-1b: P = 0.002). Increased IL-7 and IL-9 in participants with ASD after 4 weeks TTA-121 6U administration compared with placebo was verified in the confirmatory analyses in the dataset before crossover (PFDR < 0.001). Furthermore, the changes in all these cytokines during 4 weeks of TTA-121 10U administration revealed associations with changes in reciprocity score, the original primary outcome, observed during the same period (IL-7: Coefficient = -0.05, -0.10 to 0.003, P = 0.067; IL-9: -0.01, -0.02 to -0.003, P = 0.005; MIP-1b: -0.02, -0.04 to -0.007, P = 0.005). These findings provide the first evidence for a role of interaction between oxytocin and neuroinflammation in the change of ASD core social features, and support the potential role of this interaction as a novel therapeutic seed.

Abstract
Abstract
Although intranasal oxytocin is expected to be a novel therapy for the core symptoms of autism spectrum disorder, which has currently no approved medication, the efficacy of repeated administrations was inconsistent, suggesting that the optimal dose for a single administration of oxytocin is not optimal for repeated administration.
The current double-blind, placebo-controlled, multicentre, crossover trial (ClinicalTrials.gov Identifier: NCT03466671) was aimed to test the effect of TTA-121, a new formulation of intranasal oxytocin spray with an enhanced bioavailability (3.6 times higher than Syntocinon® spray, as assessed by area under the concentration–time curve in rabbit brains), which enabled us to test a wide range of multiple doses, on autism spectrum disorder core symptoms and to determine the dose–response relationship. Four-week administrations of TTA-121, at low dose once per day (3 U/day), low dose twice per day (6 U/day), high dose once per day (10 U/day), or high dose twice per day (20 U/day), and 4-week placebo were administered in a crossover manner. The primary outcome was the mean difference in the reciprocity score (range: 0–14, higher values represent worse outcomes) on the Autism Diagnostic Observation Schedule between the baseline and end point of each administration period. This trial with two administration periods and eight groups was conducted at seven university hospitals in Japan, enrolling adult males with high-functioning autism spectrum disorder. Enrolment began from June 2018 and ended December 2019. Follow-up ended March 2020.
Of 109 males with high-functioning autism spectrum disorder who were randomized, 103 completed the trial. The smallest P-value, judged as the dose–response relationship, was the contrast with the peak at TTA-121 6 U/day, with inverted U-shape for both the full analysis set (P = 0.182) and per protocol set (P = 0.073). The Autism Diagnostic Observation Schedule reciprocity score, the primary outcome, was reduced in the TTA-121 6 U/day administration period compared with the placebo (full analysis set: P = 0.118, mean difference = −0.5; 95% CI: −1.1 to 0.1; per protocol set: P = 0.012, mean difference = −0.8; 95% CI: −1.3 to −0.2). The per protocol set was the analysis target population, consisting of all full analysis set participants except those who deviated from the protocol. Most dropouts from the full analysis set to the per protocol set occurred because of poor adherence to the test drug (9 of 12 in the first period and 8 of 15 in the second period). None of the secondary clinical and behavioural outcomes were significantly improved with the TTA-121 compared with the placebo in the full analysis set.
A novel intranasal spray of oxytocin with enhanced bioavailability enabled us to test a wide range of multiple doses, revealing an inverted U-shape dose–response curve, with the peak at a dose that was lower than expected from previous studies. The efficacy of TTA-121 shown in the current exploratory study should be verified in a future large-scale, parallel-group trial.

Abstract
Background Deficiency of DNA mismatch repair (MMR) induces microsatellite instability (MSI). Pembrolizumab, an antibody targeting PD‐1 (an immune checkpoint inhibitor), is more effective against MMR‐deficient tumours than against MMR‐proficient tumours. The status of MMR is a useful biomarker for predicting the effectiveness of pembrolizumab administration. Although the status of MMR has attracted attention in skin tumours, there are few reports on MSI in extramammary Paget's disease (EMPD). Objectives To evaluate the status of MMR in patients with EMPD. Materials & Methods One hundred one patients with EMPD were included. MMR status of the genomic DNA of each subject was analysed using Promega panel (approved as a companion diagnostic agent for the administration of pembrolizumab). Results MSI testing showed the occurrence rates of MSI‐high (more than two markers are unstable), MSI‐low (one marker is unstable) and MSS (all markers are stable) tumour tissues were 0% (0/101), 1.0% (1/101) and 99.0% (100/101), respectively. Conclusion The status of MMR may not be useful for the potential therapeutic application of pembrolizumab.

Abstract
Objective: Trimethoprim-sulfamethoxazole (TMP/SMX) prophylaxis against Pneumocystis jirovecii pneumonia (PJP) is routinely administered to patients with rheumatic diseases in Japan. The present study aimed to evaluate the effect of TMP/SMX prophylaxis on PJP and non-central line-associated bloodstream infections (BSIs) in patients receiving high-dose glucocorticoids for the treatment of rheumatic diseases.Method: This study enrolled patients who were admitted between 1 October 2003 and 31 March 2018 and began high-dose glucocorticoid therapy for rheumatic diseases during hospitalization. The observation period was 4 months from the commencement of high-dose glucocorticoid therapy. The effect of TMP/SMX prophylaxis on PJP and non-central line-associated BSI was analysed.Results: Of the 437 patients included in the study, 376 received TMP/SMX prophylaxis and 61 patients did not. During the observation period, TMP/SMX prophylaxis was discontinued in 76 patients (20.2%). Three PJP cases (0.7%) occurred. Among the 399 patients included in our analysis of non-central line-associated BSI, eight experienced non-central line-associated BSI (2.0%). Among the covariates, TMP/SMX prophylaxis was associated with reduced PJP and non-central line-associated BSI incidence [odds ratio (OR) 0, 95% confidence interval (CI) 0.00-0.38, and OR 0.08, 95% CI 0.01-0.42, respectively].Conclusion: Routine TMP/SMX prophylaxis reduced the incidence of both PJP and BSI in patients with rheumatic diseases undergoing high-dose glucocorticoid therapy.

Abstract
BACKGROUND Few studies exploring the actual practices implemented for long-term mental health and psychosocial support after a natural disaster have been published. This study aimed to reveal (1) the types of activities that were actually provided as mental health and psychosocial support (MHPSS) in the long-term phase after the Great East Japan Earthquake (GEJE) and (2) the problems that must be addressed to provide post-disaster MHPSS activities. METHODS An open-ended questionnaire was sent to organizations in the Iwate, Miyagi and Fukushima prefectures that were potentially involved in providing MHPSS to communities affected by the GEJE. The organizations were asked to describe their activities and the problems that needed to be addressed to provide these support activities. The collected statements were analysed using content analysis with NVivo11. RESULTS The support activities conducted to provide MHPSS in the long-term phase after the catastrophe were diverse and classified into 7 major categories, namely, (1) one-on-one support for individuals in need of assistance, (2) support for collective activities, (3) support around living conditions and income, (4) increasing public awareness about mental health, (5) human resource development to improve response capabilities for MHPSS, (6) support for MHPSS providers, and (7) facilitating collaborations among the MHPSS activities provided to affected communities. Problems with human resources and funding were the most frequently mentioned concerns among the organizations participating in the survey. CONCLUSIONS The establishment of systems to collect and share sufficient and relevant knowledge and to coordinate organizations for long-term post-disaster postventions would be desirable.

Abstract
To investigate the dispersion of Fukushima Dai-ichi Nuclear Power Plant (FDNPP)-derived radiocesium in the Sea of Japan and western Pacific coastal region and determine the sources of radiocesium in these areas, we examined the temporal and spatial variations of 134Cs and 137Cs concentrations (activities) during 2011-2016 in seawaters around the western Japanese Archipelago, particularly in the Sea of Japan. In May 2013, the surface concentration of 134Cs was ∼0.5 mBq/L (decay-corrected to March 11, 2011), and that of 137Cs exceeded the pre-accident level in this study area, where the effects of radiocesium depositions just after the FDNPP accident disappeared in surface waters in October 2011. Subsequently, radiocesium concentrations gradually increased during 2013-2016 (∼0.5-1 mBq/L for 134Cs), exhibiting approximately homogeneous distributions in each year. The temporal and spatial variations of 134Cs and 137Cs concentrations indicated that FDNPP-derived radiocesium around the western Japanese Archipelago, including the Sea of Japan, has been supported by the Kuroshio Current and its branch, Tsushima Warm Current, during 2013-2016. However, in the Sea of Japan, the penetration of 134Cs was limited to depths of less than ∼200 m during three years following the re-delivery of FDNPP-derived radiocesium.

Abstract
AIMS Post-traumatic growth (PTG) refers to positive changes that result from coping with a major life crisis or a traumatic event. Factors influencing PTG in youth have not been well characterized but could have a great impact on overall maturation. METHODS Fourth to ninth graders (n = 3337) attending elementary or junior high schools located in a district severely damaged by the Great East Japan Earthquake completed a questionnaire, including the revised Posttraumatic Growth Inventory for Children (PTGI-C-R) along with the Post Traumatic Stress Symptoms for Children 15 items (PTSSC-15), 31 months after the event. Experience of the disaster, prior traumatic experiences, and attitudes toward memories of the disaster (rumination) were scored by their caregivers and teachers, and effects of these factors on PTG were evaluated. RESULTS There were no significant associations between PTGI-C-R and sex or experiences of the disaster. However, PTGI-C-R was negatively correlated with age (r = -0.132, P < 0.001). There was significant but very weak negative correlation between PTGI-C-R and PTSSC-15 among the children (r = -0.096, P < 0.001). PTGI-C-R was significantly associated with positive attitudes to memorial services (P < 0.001) and media coverage (P < 0.05). CONCLUSION Positive attitudes to deliberate rumination may facilitate PTG in children following natural disasters.

Abstract
BACKGROUND Dermatomyositis (DM) and systemic lupus erythematosus (SLE) have common skin features, including dermal mucin deposition and interferon signature, although their roles are unknown. OBJECTIVES To identify common or specific molecular changes in DM and SLE skin. METHODS Proteomic analysis was performed using DM and healthy skin. Glycosaminoglycans were analysed by high-performance liquid chromatography. RESULTS The expression of 60 proteins was upregulated or downregulated in DM skin compared with healthy skin in the proteomic analysis. Among those proteins, PSMB9, an immunoproteasome subunit, was upregulated in the epidermis of DM and SLE, but not in other skin diseases. Furthermore, versican V1, a core protein for glycosaminoglycans, was upregulated, while type I collagen was downregulated in the dermis of DM and SLE skin. Interferon stimulated PSMB9 expression in cultured keratinocytes and reduced collagen expression in dermal fibroblasts, but did not affect versican expression. The PSMB9 knock-down in keratinocytes led to significant suppression of transforming growth factor (TGF)-β2 and TGF-β3, inducers of versican synthesis. TGF-β3 expression was upregulated in both DM and SLE, while TGF-β2 expression was increased only in the DM epidermis. ΔDiHS-diS1, a component of heparan sulfate, was significantly increased only in DM. TGF-β2 expression significantly increased the ΔDiHS-diS1 expression in dermal fibroblasts in vitro. CONCLUSIONS The interferon signature in DM and SLE skin reduces collagen in dermal fibroblasts, whereas overexpression of PSMB9 induced by interferon stimulates versican inducers in epidermal keratinocytes. In addition, the TGF-β2-ΔDiHS-diS1 pathway may be responsible for the specific molecular change in DM skin.

Abstract
The purpose of this study was to investigate factors associated with the psychological impact of the Great East Japan Earthquake on high school students 1 year and 4 months after the disaster, and clarify support needs of the students. In the outreach program for students of three high schools in coastal areas of southern Miyagi Prefecture, Japan, 1,973 students were surveyed after obtaining informed consent for participation. Questionnaires included: the Quick Inventory of Depressive Symptomatology (QIDS-J), Self-rating Anxiety Scale (SAS), Impact of Event Scale-revised (IES-R), and Connor-Davidson Resilience Scale (CD-RISC10). All scores were compared using SPSS 20.0 J between school grades, locations of the schools, and extent of damage due to the Great East Japan Earthquake. Our analysis showed a significant positive correlation between school grades and the level of anxiety. PTSR scores, but not anxiety nor depressive scores, of students whose lives have suffered extensive damage were significantly higher than those of students who have not. Students of high schools which have suffered extensive damage and use temporary buildings showed significantly higher levels of depression and anxiety, and significantly lower resilience, compared to students of high schools which were not damaged. Although previous findings demonstrated that younger children have a higher risk of being influenced by disasters, symptoms related to PTSR and depression were found frequently in the high school students as well. Among the high school students, our analysis showed a positive correlation between the level of anxiety and school grades, probably because the disaster has affected an influential and pivotal point in their lives.

Abstract
Hypoxia has been observed in a variety of human tumor types and evaluating tumor hypoxia is important because it increases resistance to radiotherapy and chemotherapy by inducing proteomic change that allow the tumor cell to survive in their hypoxic environment. One of the major proteomic changes is HIF-1 expression, and HIF-1 has become a target for anti-cancer drugs development because of its central role in hypoxia-mediated aggressiveness of tumor cells and their resistance to therapy. Since tumor hypoxia is a key mechanism that leads to resistance of treatment, a large number of challenges for hypoxia imaging including magnetic resonance, optical, and nuclear imaging have been reported. These hypoxia imaging techniques may have potential in selecting cancer patients who would benefit from treatments that overcome the presence of hypoxia. Hypoxia imaging could also be used to document whether or not and the extent to which reoxygenation of tumors occurs during cancer treatment. One of key requirements of ideal method for imaging hypoxia is that the method should be non-invasive. From an imaging perspective, PET is also one of leading tools for imaging hypoxia because of its high spatial resolution, high sensitivity, and advantages for visualizing molecular events in living human tissue. In this review, PET-based radiopharmaceuticals including (18)F-FMISO, (18)F-FETNIM, (18)F-FAZA, and radioactive Cu-ATSM were summarized from published studies about radiosyntheses, pre-clinical data, and clinical data, which are the lead contenders for human application.

Abstract
BACKGROUND Recently, increased evidence has shown that serum micro (mi)RNA levels are a useful biomarker for the diagnosis, prognosis and therapeutic value of various diseases. However, serum miRNA has not been investigated in patients with systemic sclerosis (SSc), to our knowledge. AIM To investigate the possibility that serum levels of Homo sapiens miR-142 stem-loop (hsa-miR-142-3p), one of the miRNAs regulating the expression of integrin αV, could be a specific disease marker for SSc. METHODS Serum samples were obtained from 61 patients with SSc and 20 healthy controls. Patients with systemic lupus erythematosus (SLE), dermatomyositis (DM) and scleroderma spectrum disorder (SSD), who did not fulfil American College of Rheumatology criteria for SSc but might develop SSc in the future, were included as disease controls in this study. miRNAs were purified from serum, and miR-142-3p levels were measured with a quantitative real-time PCR assay. RESULTS Serum miR-142-3p levels in patients with SSc were significantly higher than in patients with SSD, SLE or DM, and healthy control groups. Patients with increased miR-142-3p levels tended to have a short sublingual frenulum. CONCLUSIONS Our data indicate that serum levels of miR-142-3p may be elevated specifically in patients with SSc, correlating with the severity of this disease, and may be useful diagnostic markers for the presence of SSc and for the differentiation of SSc from SSD.

Abstract
BACKGROUND Vascular abnormalities are one of the primary pathological components of systemic sclerosis (SSc). However, it has not been determined if there are also abnormalities in the formation of lymphatic vessels in SSc. OBJECTIVE To evaluate lymphangiogenic activity in SSc skin. METHODS The numbers of D2-40-positive lymphatic vessels in skin specimens from healthy control subjects and patients with SSc were counted and compared. Quantitative real-time polymerase chain reaction (PCR) was performed to determine mRNA levels of vascular endothelial growth factor (VEGF)-D and Flt-4 (fms-related tyrosine kinase 4, VEGFR-3, one of the receptors for VEGF-D) in the skin. Serum VEGF-D levels were measured with specific enzyme-linked immunosorbent assays. RESULTSZ: The number of lymphatic vessels in patients with SSc was significantly decreased compared with healthy control subjects. Mean relative transcript levels of FIGF (VEGF-D) and FLT4 (Flt-4) in skin tissue from patients with SSc were significantly increased compared with healthy control subjects. By the analysis of the association between serum VEGF-D levels and the clinical or laboratory features, we found that patients with SSc with higher serum VEGF-D levels more frequently have skin ulcers than those with normal VEGF-D levels. CONCLUSIONS A systemic increase of VEGF-D, as well as local overexpression of FIGF and FLT4, may be the cause of disturbed lymphangiogenesis in SSc skin and play a role in the pathogenesis of SSc. We showed the possibility that regulation of VEGF-D/Flt-4 signalling could lead to new treatment of skin ulcers in SSc by controlling the formation of lymphatic vessels.

Abstract
BACKGROUND The study of brain activity has been studied with the use of various techniques like electroencephalography (EEG), magnetic resonance imaging (MRI), positron emission topography (PET) and magneto-encephalography (MEG). These techniques are unsuitable because of restriction of moving of subject's body while playing "shogi (Japanese Chess)" matching However, optical topography (OT) is possible to measure. Therefore, brain activity is here studied with use of OT. MATERIALS AND METHOD The measurement and analyses of the activity of brain is carried out by cerebral blood flow with use of OT. The equipment of OP is 16-channel maximum OMM-2000 device (Shimadzu, Tokyo, Japan). Two subjects play the game, and the cerebral blood flow of only one subject is measured, since the capacity of the equipment is limited. RESULTS AND CONCLUSION When the subject does decision-making for a matter of chance during the game, the right side of frontal part (Fp2) proves more activity than that of left side (Fp1), and proves that the activity of both parts of visual field (O1, O2) communicates each other. The present study with use of OT is highly useful for observing brain activity during play of shogi game.

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
We evaluated the sperm recovery rate in non-obstructive azoospermia (NOA) patients presenting with bilateral testicular atrophy characterized by testes volume of less than 10ml and FSH levels exceeding 20 mIU/ml (group NOA-1), and compared the results to those NOA cases displaying unilateral testis volume exceeding 10 ml or FSH levels less than 20 mIU/ml (group NOA-2). Sperm retrieval was conducted in 261 azoospermic patients from April 1995 to December 2002. Forty-six NOA-1 and 37 NOA-2 individuals underwent microdissection TESE or 3-4 standard biopsies. Sperm recovery was achieved in 11 (24%) and 12 (32%) cases in NOA-1 and NOA-2, respectively. All couples received ICSI. Four clinical pregnancies (36.3%) in NOA-1 and two (17%) in NOA-2 resulted. Five subsequent healthy deliveries were obtained. NOA patients presenting with bilateral severe atrophic testes volume and obviously elevated FSH levels exhibited approximately 24% probability of sperm recovery. On the other hand, NOA characterized by testicular atrophy or elevated FSH levels displayed probability of approximately 32%. Differences in sperm recovery were not evident between NOA-1 and NOA-2. No successful pre-operative predictors of sperm recovery were identified.

Abstract
We report a case in which a healthy 18-year-old girl acted as a liver donor for her mother, who had a terminal hepatic illness with a one-year survival probability of 2% without liver transplantation. The daughter, who was the only relative to have a blood type compatible with her mother, offered to donate after the surgeons explained the situation. Our ethical committee required a psychiatrist to evaluate her psychiatric status and competence, and address ethical concerns. We assessed elements of informed consent: disclosure of information, competence, and voluntariness, as well as psychiatric problems and the psychosocial status. The disclosure of information was adequate. The girl's competence was of a sufficient level for her to appreciate that the procedure could have negative results on both her and her mother. She was able to logically assess the consequences of having the operation and those of declining it. It was very difficult to evaluate whether she was undergoing the procedure completely voluntarily, because she was the only one with a blood type compatible with her mother, who was near death, and because the girl was underage. Psychological issues related to her age were that she depended on her family economically and psychologically, and that the opinions of her family influenced her. In this case, we concluded that she had consented voluntarily, because there was no coercion and no unjust pressure to donate, and because she understood that consent could be withdrawn at any time. Although she was underage and the psychological assessment revealed that she experienced some conflict in this difficult situation, her competence was considered intact. Medical evaluation and laboratory testing were satisfactory, and the ethical committee determined that she was suitable to donate. The operation was performed and was successful. The Japanese Transplantation Society has since established ethical guidelines regarding potential living donors who are underage; one precondition for donation is that a psychiatrist must evaluate whether or not the competence of the donor is equal to that of an adult. As the literature contains no reports of the evaluation of potential donors who are underage, we need to consider the format and contents of such psychiatric evaluations and ethical concerns.

Abstract
For the establishment of an effective comprehensive anti-suicide policy, a multifaceted strategy including primary, secondary, and tertiary prevention measures is needed. In urban cities, however, there are many obstacles to projects such as comprehensive programs for suicide prevention. In Sendai city, which has a population of approximately 1,000,000, a comprehensive anti-suicide project was launched as a public enterprise as a pioneer among ordinance-designated cities in Japan. This project was supported by several important factors. 1) A series of epidemiological observation and intervention studies on depression among the elderly had previously been conducted in a large residential district. As a result, a comprehensive community program for depression among the elderly was implemented as a public enterprise and a subsequent decreasing trend in the later-life suicide rate was found. 2) The municipal authorities recognized the importance of the anti-suicide program and made an effort to reorganize the existing health-related programs in terms of suicide prevention. 3) the action of the municipality was facilitated by the passing of an anti-suicide law by the National Diet in 2006 and the establishment of fundamental principles for a comprehensive anti-suicide policy by the National Diet in 2007. 4) The activities of nongovernmental groups also influenced the municipality. In order to establish a comprehensive anti-suicide program in urban cities with a large population, an interaction model in which various governmental and nongovernmental networks influence and activate each other should be considered.

Abstract
146 MD-TESE procedures were performed in 74 patients presenting with non-obstructive azoospermia (NOA). Five of the 74 patients displayed a history of chemotherapy. Etiology of chemotherapies included testicular cancer, osteosarcoma, Ewing sarcoma, and malignant lymphoma of the stomach. Post-chemotherapy duration was 2.5-18 years. All patients underwent MD-TESE using local anesthesia with spermatic block and sedation. Extracted sperm was cryopreserved for ICSI. Histopathologic examination revealed Sertoli cell-only syndrome in all five patients; however, sperm were retrieved in 3 subjects. Post-chemotherapy MD-TESE and ICSI can be applied successfully in some patients with NOA. However, freezing semen prior to chemotherapy is recommended.

Abstract
Many diabetics carry a portable-type blood glucose monitor and collect their own blood to examine their blood glucose levels daily (self monitoring of blood glucose, SMBG). The use of a physical condition variable was suggested in order to estimate the blood glucose level for diabetics. Four sets of data, including FBG, food intake, metabolic rate and physical condition, were collected from four Type 1 diabetics over a five-month period. Using these data, an increasing or decreasing tendency for FBG for the next day was estimated using the data mining method. The results revealed that the estimation accuracy was improved when a physical condition variable was used. An average correspondence rate of 81 % was observed, with a maximum of 90 %. These results indicated that the data mining method could be effective in the estimation of blood glucose levels.

Abstract
We encountered the co-existence of an aberrant origin of the right subclavian artery and a myocardial bridge on the left anterior descending coronary artery in the cadaver of an 80-year-old Japanese woman during the course of educational dissection at Nagoya City University Medical School. We document the precise gross anatomical findings with some morphometric measurements. Neither an aberrant origin of the right subclavian artery nor the cardial myocardial bridge is a very rare anomaly, but a case of both anomalies being found in the same body is very rare. We believe this is the first report of the simultaneous occurrence of these two anomalies.

Abstract
The authors retrospectively examined whether long-term administration of tranilast improves semen parameters in severe oligoasthenozoospermia. Fifty-two patients presenting with sperm concentration of less than 10 x 10(6) sperm/mL were enrolled. Subjects were partitioned into 3 groups as follows: patients displaying an atrophic testis with elevated (FSH) (group 1), patients exhibiting normal testicular volume with elevated FSH (group 2), and patients with normal testicular volume and normal FSH levels (group 3). Tranilast (300mg/day) was administered until pregnancy was achieved or for a period of up to 12 months. Sperm concentration was significantly increased at 3 months in 16 subjects (44%) in groups 1 and 3. In group 2, sperm concentration was increased at 12 months (5 of 16 subjects; 31%). Total sperm count was obviously elevated at 3 months in groups 1 and 2, and at 6 months in group 3. Six pregnancies were achieved via natural intercourse. Tranilast, a mast cell blocker, demonstrates a certain clinical benefit in terms of improvement of semen parameters involving severe oligoasthenozoospermia, but it does not appear to afford clinical benefit in long-term administration.

Abstract
The purpose of this prospective study was to detect symptomatic cerebral vasospasm in aneurysmal subarachnoid haemorrhage (SAH) by a non-invasive mean cerebral blood flow (mCBF) quantification using 99mTc-ethyl cysteinate dimer. Measurement of mCBF without blood sampling and single photon emission tomography (SPECT) were performed at 1 and 7 days after surgery in 35 consecutive SAH patients, of whom 16 were examined at day 30 as well. A decrease in mCBF of more than 10% on day 7 versus day 1 was considered to indicate vasospasm. On visual interpretation of SPECT, a perfusion decrease which appeared newly on day 7 was considered to indicate vasospasm. In total, nine of 35 patients had cerebral vasospasm confirmed by computed tomography (CT) and/or angiography. The mCBF measurement showed a 77.8% (7/9) sensitivity, a 88.5% (23/26) specificity, a 70.0% (7/10) positive predictive value, and a 92.0% (23/25) negative predictive value. SPECT yielded a 33.3% (3/9) sensitivity, a 73.1% (19/26) specificity, a 30.0% (3/10) positive predictive value, and a 76.0% (19/25) negative predictive value. On SPECT, decreased perfusion was observed in most of the patients at clipping sites, which might represent post-operative transient abnormal perfusion and should not be read as vasospasm. In conclusion, this mCBF measurement is more accurate than visual interpretation of SPECT for detecting vasospasm.

Abstract
BACKGROUND Transitional cell carcinoma of the prostate in patients with bladder cancer appears to influence the prognosis and affects the decision about therapeutic modality. Therefore, it is important to characterize transitional cell carcinoma associated with bladder cancer. METHODS From April 1980 to December 1998, 81 male patients underwent total cystoprostatectomies for transitional cell carcinoma of the bladder. The 81 cystoprostatectomy specimens were examined to clarify the characteristics of prostatic involvement by transitional cell carcinoma. The extent, origin, mode of spread and risk factor of prostatic involvement as well as the prognosis were investigated. In 13 of 15 patients with prostatic involvement the prostate was examined by sequential step sections. RESULTS Prostatic involvement was observed in 15 of 81 patients (18.5%). Prostatic urethral involvement, invasion to prostatic duct/acinus, prostatic stromal invasion and extraprostatic extension and/or seminal vesicle involvement were recognized in 12 (80%), 14 (93.3%), six (40%), and five (33.3%) of the 15 patients, respectively. Twelve of the 15 patients (80%) with prostatic involvement had papillary or non-papillary tumors (i.e. carcinoma in situ) both in the prostatic urethra and prostatic duct. In 10 of these 12 patients (88.3%), there was contiguity between prostatic urethral and ductal tumors. Seven of the 23 patients (30.4%) with carcinoma in situ of the bladder showed prostatic involvement, which increased to 50% in the presence of carcinoma in situ of the trigone or bladder neck. CONCLUSIONS Eighty per cent of the patients with prostatic involvement showed papillary or non-papillary tumors both in the prostatic urethra and prostatic duct. There was a high level of contiguity between both tumors. Patients with carcinoma in situ of the trigone or bladder neck revealed significantly higher incidence of prostatic involvement.

BACKGROUND We reviewed the results of endoscopic ureteral incision for benign ureteral stricture, ureteropelvic junction obstruction and ureteroenteroanastomotic stricture using the holmium laser. METHODS We carried out endoscopic ureteral incision using the holmium laser through an 8-Fr semirigid or 6.9-Fr flexible ureteroscope on 17 ureters in 15 patients. Balloon dilatation was not necessary before insertion of the ureteroscope. The stricture was incised with the holmium laser using a 200-365 microm fiber through the working channel of the ureteroscope. After completion of the incision, a 12-Fr double-J catheter was left for 6 weeks. Thereafter patients were followed by renal scan and/or ultrasound and excretory urography at 3-6 month intervals. RESULTS The mean operative time was 65 min (18-135 min). The stricture resolved completely in 86.7% of cases at an average follow up of 20.5 months (11-32 months). CONCLUSIONS The holmium laser endoscopic ureteral incision was associated with a good outcome in our series. We recommend this procedure to be employed initially because it is less invasive and has a favorable outcome.

Abstract
Recently, we have shown that alpha 2,8-linked disialic acid (diSia) residue occurs in glycoproteins more frequently than ever recognized (Sato, C., Fukuoka, H., Ohta, K., Matsuda, T., Koshino, R., Kobayashi K., Troy, F. A., II, and Kitajima, K. (2000) J. Biol. Chem. 275, 15422--15431). In the course of identification of the diSia-containing glycoproteins in mammals, the 30-kDa glycoprotein was found in bovine serum. The 30-kDa glycoprotein was shown to be the bovine adipo Q, an adipocyte-specific protein, based on the partial amino acid sequences and the immuno-cross-reactivity with the recombinant mouse adipo Q. The bovine adipo Q was shown to have no N-linked but O-linked glycan(s) containing the diSia epitope, Neu5Ac alpha 2-->8Neu5Ac alpha 2-->3Gal. Furthermore, the diSia epitope was also found in the mouse adipo Q in serum as well as in the 3T3-L1 cells that are fully differentiated into adipocytes. Notably, among the known alpha 2,8-sialyltransferases, only the alpha 2,8-sialyltransferase III mRNA was detected in the 3T3-L1 cells at any stages of differentiation, and the recombinant alpha 2,8-sialyltransferase III could sialylate the purified bovine adipo Q. Thus, this study clearly provides the new findings that adipo Q is the diSia-containing glycoprotein and a physiological substrate of alpha 2,8-sialyltransferase III, whose substrates have not been identified so far.

Abstract
This study presents the first direct evidence for herpes simplex virus type 1 (HSV-1) infection in the neurons of the vestibular ganglion. Although many investigators have reported electron microscopic evidence of HSV-1 infection in sensory ganglia, HSV-1 infection in the vestibular ganglion has not been described. Vestibular ganglion neurons have a unique structure, with a loose myelin sheath instead of the satellite cell sheath that is seen in other ganglia. This loose myelin is slightly different from compact myelin which is known as too tight for HSV-1 to penetrate. The role of loose myelin in terms of HSV-1 infection is completely unknown. Therefore, in an attempt to evaluate the role of loose myelin in HSV-1 infection, we looked for HSV-1 particles, or any effects mediated by HSV-1, in the vestibular ganglion as compared with the geniculate ganglion. At the light microscopic level, some neurons with vacuolar changes were observed, mainly in the distal portion of the vestibular ganglion where the communicating branch from the geniculate ganglion enters. At the electron microscopic level, vacuoles, dilated rough endoplasmic reticulum and Golgi vesicles occupied by virus were observed in both ganglia neurons. In contrast, viral infections in Schwann and satellite cells were observed only in the geniculate ganglion, but not in the vestibular ganglion. These results suggest that loose myelin is an important barrier to HSV-1 infection, and it must play an important role in the prevention of viral spread from infected neurons to other cells.

Abstract
A 14-year-old boy complained of left flank pain. He had been given high-dose corticosteroid therapy for chronic inflammatory demyelinating polyneuropathy (CIDP). Retrograde pyelography revealed irregular defects at the left ureteropelvic junction (UPJ), and ureteroscopy demonstrated ureteral polyp. The polyp was removed and histologically diagnosed as fibroepithelial polyp. Hypercalciuria due to the corticosteroids and bedridden was assumed to have been a causative factor in the stone formation. To our knowledge, this is the first report of a ureteral fibroepithelial polyp in children associated with urolithiasis, and associated with CIDP.

Abstract
A 54-year-old man, who had undergone left radical nephrectomy due to a renal cell carcinoma 2 years previously, had received adjuvant interferon (IFN) therapy for 2 years. One month has passed after IFN therapy, when he started to complain of muscle pain. The serum FT3 and FT4 levels were lower than normal range. We diagnosed for hypothyroidism induced by IFN therapy, and he was treated with thyroxine. His serum FT3 and FT4 levels were increased after the initiation of the thyroxine therapy. Many reports of hypothyroidism induced by IFN therapy have been found during the treatment for chronic hepatitis. The hypothyroidism induced after IFN therapy of renal cell carcinoma is very rare. It should be brought to attention that IFN therapy induces hypothyroidism not only during treatment period, but also after the treatment. Careful examination after the therapy is mandatory.

Abstract
In this report, we examine the case of a 6-year-old girl with a mixed oligodendroglioma demonstrating uncommon neuroradiological images. CT and MR showed an intratemporal mass with multilocular cystic formation and intratumoral massive calcification, suggestive either of astrocytoma, dysembryoplastic neuroepithelial tumor, or ganglioglioma as a presumptive differential diagnosis. The tumor was almost completely removed. Post-operative histological examination revealed a mixed oligodendroglioma with a small component of astrocytoma. The combination of radiotherapy and chemical treatment was supplemented.

Abstract
In order to investigate the mechanism of Bell's palsy, we developed an animal model of facial nerve paralysis induced by the reactivation of herpes simplex virus type 1 (HSV-1). Eight weeks after recovery from facial nerve paralysis caused by inoculation with HSV-1, the mice were treated with auricular skin scratch at the site of the previous inoculation, or with intraperitoneal injection of anti-CD3 monoclonal antibody (mAb), or combination of both procedures. No mice developed facial nerve paralysis when they were treated with either auricular scratch or mAb injection alone. In contrast, 20% of mice developed facial nerve paralysis with the combined treatment. With one exception, no mouse treated with either auricular scratch or mAb injection showed HSV-I DNA in their facial nerve tissue, whereas 4 out of 6 mice receiving both treatments showed HSV-1 DNA on day 10 after treatment. Histopathological findings showed neuronal degeneration in the geniculate ganglion and demyelination of the facial motor nerve in paralyzed mice. These findings suggest that a combination of stimuli, local skin irritation, and general immunosuppression is essential for successfully inducing facial nerve paralysis in mice with latent HSV-1 infection.

Abstract
Clinical applications of nuclear medicine in pulmonary hypertension (PH) include: 1) Differentiation of primary from chronic thromboembolic form of PH by mismatched ventilation/perfusion defects, 2) Quantification of right ventricular ejection fraction to estimate cardiac functional derangement, 3) Estimation of right ventricular hypertrophy or pressure overload by increased accumulation of radioactive myocardial perfusion agents, and 4) Estimation of myocardial sympathetic nervous function or fatty acid metabolism. Gravity dependent shift of pulmonary perfusion detected by perfusion scintigraphy has also been utilized for estimating severity of PH. Positron emission tomography (PET) has visualized distribution of pulmonary adrenergic receptors and angiotensin converting enzyme. PET, in addition to F-18 FDG lung tumor PET, should be watched for because it may visualize and quantify other bioactive substances and receptors in the lung.

Abstract
A 57-year-old man who had received radical urethrocystectomy and Indiana urinary diversion 6 months earlier was treated for ureteroenteric anastomosis stricture (left side) using a Holmium:YAG laser via antegrade approach. The availability of small (6.9 Fr) flexible ureteroscope, as well as the use of the Holmium:YAG laser has facilitated the ability to precisely incise the stricture under direct endoscopic visualization. The technique is described for laser endoureterotomy in a patient with ureteroenteric stricture following Indiana urinary diversion.

Abstract
Several novel tricyclic compounds with a unique amine moiety (1, 2a--i) were designed and prepared based on the structure of triperiden for the development of anti-influenza virus agents. An in vitro antiviral assay showed that 1-(1-azabicyclo[3.3.0]octan-5-yl)-1-(4-fluorophenyl)-1-(2-tricyclo[3.3.1.1(3.7)]decyl)methan-1-ol hydrochloride (2f) has a potent anti-influenza A virus activity. Furthermore, since 2f was well tolerated in mice, 2f is promising as a novel anti-influenza virus agent for humans.

Abstract
Although many drug treatments have been reported to theoretically improve semen parameters in male infertility, a standard method has not been established. The authors examined whether tranilast, a mast cell blocker, improves fertility and/or semen parameters in severe oligozoospermia. Seventeen patients with a sperm density of less than 10 x 10(6) sperm/mL and their fertile partners were enrolled in this study. Patients were prescribed tranilast 300 mg/day for at least 12 weeks. Semen and blood samples were collected before and after the prescription of tranilast for 12 weeks. Semen parameters, serum gonadotropins, luteinizing hormone, follicle-stimulating hormone, serum testosterone, and testicular size were evaluated. One patient complained of mild drowsiness during treatment. The sperm count was significantly increased after administration of tranilast in 7 patients (41.1%), although sperm motility was not altered. Semen volume and normal morphology were also unaltered. Three pregnancies were achieved. Endocrine profile and testicular size were unchanged. Tranilast, a mast cell blocker, is clinically useful for the treatment of severe idiopathic oligozoospermic men.

Abstract
OBJECTIVE We sought to assess the efficacy of transmastoid decompression after steroid treatment. STUDY DESIGN One hundred one adults with Bell palsy having denervation exceeding 95% after steroid treatment were divided into 2 groups. In 58 patients decompression from the labyrinthine segment to the stylomastoid foramen was performed, and the remaining 43 patients were only followed up. Using the Yanagihara score and House Brackmann grading system, the recovery from the palsy was assessed. RESULTS There was a statistically significant difference in the final facial score of the 2 groups. Within 60 days after the onset, the chance of better recovery from the palsy was higher in the patients with decompression. CONCLUSION In the era of steroid treatment, we cannot discard the transmastoid decompression of the facial nerve in the treatment of severe Bell palsy with profound denervation, although further effort is needed to obtain definitive evidence to show the benefit of the operation.
