Abstract
BACKGROUND Oscillatory activities observed in multiple regions are closely associated with the experience of pain. Specifically, oscillatory activities within the theta- and beta-frequency bands, observed in the left dorsolateral prefrontal cortex (DLPFC), have been implicated in pain perception among healthy individuals and those with chronic pain. However, their physiological significance remains unclear. METHODS We explored the modulation of pain perception in healthy individuals by theta- and beta-band transcranial alternating current stimulation (tACS) over the left DLPFC and examined the relationship between the modulation effect and magnitude of the electric field elicited by tACS in the left DLPFC using computational simulation. RESULTS Our findings revealed that both theta- and beta-tACS increased the heat pain threshold during and after stimulation. Notably, the simulated electric field magnitude in the left DLPFC exhibited an inverted U-shaped relationship with the pain modulation effect for theta-tACS. CONCLUSIONS Our study findings suggested that there would be an optimal electric field strength to produce a high analgesic effect for theta-tACS. SIGNIFICANCE The application of theta- and beta-tACS interventions targeting the left DLPFC might facilitate the treatment of chronic pain. Furthermore, the attainment of effective pain modulation via theta-tACS over the DLPFC warrants the use of optimal stimulus intensity.

Abstract
Cosmic rays are energetic charged particles from extraterrestrial sources, with the highest-energy events thought to come from extragalactic sources. Their arrival is infrequent, so detection requires instruments with large collecting areas. In this work, we report the detection of an extremely energetic particle recorded by the surface detector array of the Telescope Array experiment. We calculate the particle's energy as [Formula: see text] (~40 joules). Its arrival direction points back to a void in the large-scale structure of the Universe. Possible explanations include a large deflection by the foreground magnetic field, an unidentified source in the local extragalactic neighborhood, or an incomplete knowledge of particle physics.

Abstract
A 9-year-old spayed female crossbreed cat with chief complaints of anorexia and hypersalivation had high serum concentrations of ammonia and fasting and postprandial total bile acid. Therefore, she was referred to our hospital. On the first evaluation, haematology, serum chemistry, radiography and ultrasonography findings suggested that she had a congenital portosystemic shunt. CT revealed a shunt vessel from the left gastric vein to the left pulmonary vein. During median celiotomy and sternotomy, gross findings and mesenteric portography revealed abnormal vessel shunting from the left gastric vein to the left pulmonary vein. Complete ligation of the shunt vessel was achieved. She recovered without any complications. Postoperative serum chemistry revealed that ammonia and total bile acid levels decreased to within the reference intervals. This report is the first to describe the clinical features and surgical outcome of a cat with a congenital portopulmonary shunt.

Abstract
Two dogs with anorexia and rapid weight loss were referred to our hospital due to a right renal mass and several pulmonary nodules. Both dogs underwent needle core biopsy of the mass, followed by transarterial chemoembolisation of the renal mass. A catheter was inserted from the femoral artery and advanced into the right renal artery. A suspension of carboplatin (100 mg/m2 ) and equivalent lipiodol was administered via the inserted multipurpose catheter. Immediately after, under fluoroscopic guidance, pulse injections of small amounts of gelatin particles (diameter 1 mm) dissolved in iohexol were administered until complete embolisation of the renal artery. Histopathologic diagnosis was renal cell carcinoma in both dogs. Clinical signs improved for 134 and 358 days after transarterial chemoembolisation. In addition, postoperative radiographs demonstrated a decrease in the tumour size. The dogs died 215 and 525 days after the initial evaluation, respectively. As a palliative treatment, transarterial chemoembolisation might help reduce the tumour volume and improve the quality of life in dogs with renal cell carcinoma and distant metastases.

Abstract
BackgroundIn clinical practice for systemic lupus erythematosus (SLE), the concept of “treat to target” has been introduced with an established goal of reducing glucocorticoid dose as much as possible while controlling disease activity. Although it has been shown that various personality characteristics of patients with SLE affect their disease activity and damage, it is not clear whether the personality characteristics of attending physicians affect the outcomes of patients with SLE. Grit is a personality trait characterized by perseverance and passion for achieving long-term goals.ObjectivesThis study aims to evaluate the relationship between attending physicians’ grit personality characteristics and treatment goal achievements in patients with SLE.MethodsA cross-sectional study was conducted on 386 patients with SLE in five referral hospitals in Japan. The main exposure was the “perseverance” and “consistency” (scores 1-5) of the attending physicians, as measured by the Short Grit Scale, and the primary outcome was the achievement of the Lupus Low Disease Activity Score (LLDAS). Considering the clustering of achievement of LLDAS by each attending physician, the association between attending physician’s personality and LLDAS was analyzed by logistic regression with cluster robust variance estimation. Odds ratios to assess the relationship between perseverance and consistency and LLDAS were estimated with adjustment for confounders (age, sex, disease duration, hydroxychloroquine use, immunosuppressant use, and Systemic Lupus International Collaborating Clinics-Damage Index). We used multiple imputation to handle the uncertainty caused by missing values of potential confounders on the assumption of missing at random.ResultsThe median age of the patients was 45 years (interquartile range[IQR],36-56), 88% were female, and the median disease duration was 152 months(IQR, 80-240). Thirty-seven doctors were in charge of the patients (1-79 patients/each doctor). The median age of the attending physicians was 40 years (IQR, 35-43), and 19% were female. The median perseverance and consistency scores of attending physicians were 3.1 (IQR, 3.0-3.5) and 3.3 (IQR, 2.8-3.8), respectively. Of the enrolled patients, 154 (40%) had achieved LLDAS. The attending physicians with a lower consistency score of <3 were more frequent in the patients who achieved LLDAS (40% vs. 29%, p=0.026). The lower consistency score of attending physicians was still related to LLDAS independently (adjusted odds ratio 1.63, 95% confidential interval 1.17-2.27). There was no association between the achievement of LLDAS and perseverance.ConclusionThe grit personality characteristics of the attending physician may affect the achievement of treatment goals in patients with SLE.Disclosure of InterestsKEN-EI SADA Speakers bureau: I received speaker’s fees from Glaxo Smith Kline K.K., Grant/research support from: I received a research grant from Pfizer Inc., Yoshia Miyawaki: None declared, Kenta Shidahara: None declared, Shoichi Nawachi: None declared, Yu Katayama: None declared, Yosuke ASANO: None declared, Keigo Hayashi: None declared, Keiji Ohashi: None declared, Eri Katsuyama: None declared, Takayuki Katsuyama: None declared, Mariko Narazaki: None declared, Yoshinori Matsumoto: None declared, Nao Oguro: None declared, Yuichi Ishikawa: None declared, Natsuki Sakurai: None declared, Chiharu Hidekawa: None declared, Ryusuke Yoshimi: None declared, Takanori Ichikawa: None declared, Dai Kishida: None declared, Yasuhiro Shimojima: None declared, Noriaki Kurita: None declared, Nobuyuki Yajima: None declared

Abstract
BackgroundIt is well known that providing appropriate health information to patients with systemic lupus erythematosus (SLE) has an advantage in the treatment decision making process. In modern information society the growing popularity of smartphones and social networking services, patients have more access to online health information. However, there are concerns that Internet use may inversely affect the shared decision making (SDM) process with their attending physicians if they receive inaccurate information.ObjectivesThis study aimed to investigate how online information gathering behavior affects SDM with their attending physicians.MethodsIn this cross-sectional study, information of 386 patients with SLE, which were enrolled from five Japanese institutions between June 2020 and August 2021, were analyzed. The main exposure was time spent on the Internet per day (excluding time used for working). It was divided into four categories (none, <1 hour, 1-2 hours, > 2 hours). Patients were asked to select the source of health care information they would like to access first and were categorized into physicians, the Internet, and other media sources (family and friends, healthcare professionals other than physicians, or TV and radio, etc.). Outcome was shared decision making measured via the 9-item Shared Decision Making Questionnaire (SDM-Q-9 [scores 0-100]). To assess the relationship between the time of Internet use and SDM, we fitted general linear models adjusted for age, gender, education level, household income, marital status, history of cancer, disease duration, and disease activity. Chained equations were used to impute missing values of covariates.ResultsThis study ultimately employed 334 patients whose mean age and female ratio were 45.3 years (standard deviation 13.8) and 87.7%, respectively. 68.9% of the patients indicated that they would like to access their physicians first, and 19.5% indicated that they would like to access the Internet first. Compared to patients who chose their physician as their first access to health information, there was no difference in SDM-Q-9 among patients who chose the Internet, but patients who chose other media had significantly lower SDM-Q-9 (-7.7 point, 95% confident interval [CI] -14.4 to -0.92, P=0.026). Besides, SDM-Q-9 scores were significantly lower in patients who did not use the Internet compared to those who used it for more than two hours except for their work activities (-9.6, 95%CI -18.9 to -0.26, P=0.044).ConclusionThe present study suggests that SDM between physicians and patients is positively rather than adversely associated with online information-gathering behavior. Rheumatologists also need to be aware that how patients prefer to access health information to establish a good physician-patient relationship for SDM. In addition, rheumatologists may need to introduce their patients to websites offering appropriate health information.Disclosure of InterestsNone declared

Abstract
BackgroundInformation technology has expanded the gap in patient health literacy (HL), and HL has various implications on the trust in patient-doctor relationship. Previously, only functional HL, the ability to interpret health information through reading and writing skills, has been studied in patients with SLE (1).ObjectivesWe examined how trust in physicians is affected by the broader concept of HL, including communicative HL, the ability to extract health information from communication to use, and critical HL, the ability to discern and use such information (2).MethodsThis cross-sectional study enrolled 362 SLE patients at 5 sites between June 2020 and August 2021. Three domains of HL (i.e., functional HL, communicative HL, and critical HL) were assessed using the 14-item FCCHL scale (range: 1-4 points for each domain). The outcomes were patients’ trust in their physicians and physicians in general and were measured using the Japanese version of the 5-item Wake Forest Physician Trust scales (range: 0-100 points for each scale). General linear models adjusted for age, gender, education, income, SLEDAI, disease duration, depression, and hours of Internet use were conducted. Subsequently, a series of general linear models were then fit to each of the three domains of HL to examine whether or not it was associated with the aforementioned covariates.ResultsThe median age of the patients was 45 (interquartile range [IQR],34-55), 88% were female. The median value of SLEDAI was 4 ([IQR], 2-8), Trust in one’s physician was 80 ([IQR], 70-95) and trust in physicians generally was 65 ([IQR], 50-80). Trust in one’s physician increased with higher functional and communicative HL (per 1-pt increase, 3.2 [95%CI 0.7 to 5.9]; 5.4 [95%CI 1.6 to 9.3]). Trust in doctors generally increased with higher communicative HL and decreased with higher critical HL (per 1-pt increase, 6.8 [95% CI 2.0 to 12]; -6.7 [95% CI -12 to -1.9]). Lower functional HL was associated with older age and depression, while higher HL was associated with higher educational level. Higher communicative HL and critical HL were each associated with longer Internet use.ConclusionIn patients with SLE, higher trust in one’s physician was associated with both functional and communicative HL, while higher trust in physicians generally was associated with higher communicative HL and lower critical HL. Our findings suggest that trusting relationships may be fostered by the encouragement of rheumatologists to cultivate patients’ ability to share their health problems with their physicians and family members and to obtain useful health information (i.e., communicative HL), rather than to improve their ability to discern health information (i.e., critical HL).References[1]Maheswaranathan M, Cantrell S, Eudy AM, Rogers JL, Clowse MEB, Hastings SN, et al.

Abstract
Transverse single-spin asymmetries of very forward neutral pions generated in polarized p+p collisions allow us to understand the production mechanism in terms of perturbative and nonperturbative strong interactions. During 2017, the RHICf Collaboration installed an electromagnetic calorimeter in the zero-degree region of the STAR detector at the Relativistic Heavy Ion Collider (RHIC) and measured neutral pions produced at pseudorapidity larger than 6 in polarized p+p collisions at sqrt[s]=510 GeV. The large nonzero asymmetries increasing both in longitudinal momentum fraction x_{F} and transverse momentum p_{T} have been observed at low transverse momentum p_{T}<1 GeV/c for the first time, at this collision energy. The asymmetries show an approximate x_{F} scaling in the p_{T} region where nonperturbative processes are expected to dominate. A non-negligible contribution from soft processes may be necessary to explain the nonzero neutral pion asymmetries.

Abstract
Background Spermatozoa become competent for fertilization during transit through the epididymis. As spermatozoa from the proximal caudal epididymis can fertilize eggs, proteins from the caput and corpus epididymis are required for sperm maturation. Objectives Microarray analysis identified that more than 17,000 genes are expressed in the epididymis; however, few of these genes demonstrate expression restricted to the epididymis. To analyze epididymis‐enriched gene function in vivo, we generated knockout (KO) mutations in nine genes that are abundantly expressed in the caput and corpus region of the epididymis. Materials and methods KO mice were generated using the CRISPR/Cas9 system. The histology of the epididymis was observed with hematoxylin and eosin staining. KO males were caged with wild‐type females for 3–6 months to check fertility. Results We generated individual mutant mouse lines having indel mutations in Pate1, Pate2, or Pate3. We also deleted the coding regions of Clpsl2, Epp13, and Rnase13, independently. Finally, the 150 kb region encoding Gm1110, Glb1l2, and Glb1l3 was deleted to generate a triple KO mouse line. Histology of the epididymis and sperm morphology of all KO lines were comparable to control males. The females mated with these KO males delivered pups at comparable numbers as control males. Discussion and conclusion We revealed that nine genes abundantly expressed in the caput and corpus epididymis are dispensable for sperm function and male fecundity. CRISPR/Cas9‐mediated KO mice generation accelerates the screening of epididymis‐enriched genes for potential functions in reproduction.

Abstract
Transverse single spin asymmetry, AN, of very forward π0 production from polarized p + p collisions provides new information toward an understanding of its production mechanism. AN of forward π0 in the pseudorapidity region of 3 < η < 4 has been described by the partonic structure of the proton in the perturbative QCD framework. However, recent data indicates a potential contribution from not only partonic but also diffractive interactions. In order to provide a new insight on the origin of the AN, we measured the very forward π0 production in the pseudorapidity region of 6 < η from √s = 510 GeV polarized p + p collisions at RHIC in 2017. We report our measurement of the very forward π0 over the transverse momentum range of 0 < pT < 1 GeV/c and the preliminary result.

Abstract
The Large Hadron Collider forward and the Relativistic Heavy Ion Collider forward experiments measured forward particles produced in high-energy hadron collisions at the LHC and RHIC. Using compact calorimeters neutral particles produced in pseudorapidities η >8.4 and η >6.0 are observed by the respective experiments. Because the collision energies ranging from 0.51 TeV to 13 TeV correspond to the cosmic-ray equivalent energies of 1014 to 1017 eV, the measurements are important to understand the hadronic interaction relevant to extensive air shower measurements. This paper reviews recent results of LHCf and initial performance of RHICf that took data in the 2017 RHIC operation.

Abstract
OBJECTIVE We aimed to describe the clinical characteristics and treatment course of hypertrophic pachymeningitis (HPM) in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). METHODS We retrospectively analysed 15 patients (11 men and four women). HPM was diagnosed based on thickening and enhancing of the brain and/or spinal dura mater on gadolinium-enhanced magnetic resonance imaging (MRI) T1 sequence. RESULTS The median age at HPM onset was 60 years. Headache and cranial nerve impairment were observed in 14 and 10 patients, respectively. Otitis media and/or mastoiditis were found as complications of AAV in 11 patients. Fourteen patients were classified as having granulomatosis with polyangiitis (GPA). Single-positive myeloperoxidase-ANCA, single-positive proteinase 3-ANCA, and double-positive ANCA were identified in seven patients, five patients, and one patient, respectively. With MRI, thickening of the dura mater in the cranial fossa and tentorium cerebelli was found in 10 and eight patients, respectively. For remission induction, all patients were treated with corticosteroids, and immunosuppressants were added in 10 patients. Dura mater thickening partially improved in all patients, and cranial neuropathy completely remitted in eight patients. In a median follow-up of 43 months, four patients had HPM relapse and underwent reinduction therapy. All six patients treated with cyclophosphamide at initial therapy did not relapse. CONCLUSIONS HPM was mostly associated with patients with GPA with otitis media and/or mastoiditis having either type of ANCA serology. Treatment with corticosteroids with or without immunosuppressants was effective. However, HPM relapse occasionally occurred, especially when cyclophosphamide was not used in initial treatment.

Abstract
Despite progressive treatments with tandem stem-cell transplantation, patients with incurable myeloma eventually succumb to relapsed or refractory disease if left untreated. Promising agents such as proteasome inhibitors and immunomodulating imide drugs (imids), including the newer-generation agent pomalidomide, in combination with lower-dose dexamethasone, have been shown to be effective and to significantly improve and prolong survival in pretreated patients. Although the incidence of pomalidomide hypersensitivity reaction (hsr) in this class of drugs is not as well known, we have documented cutaneous toxicity (grade 3 by the Common Terminology Criteria for Adverse Events, version 4) in 2 separate cases (not yet published). Because the imids are chemically, structurally, and pharmacologically similar, it is not unreasonable to consider possible cross-reactivity in pomalidomide recipients who developed hsr when receiving previous lines of imids. As a patient's advocate, it is only prudent to provide a responsible, and yet practical, means to better address cross-sensitivity for patients. Intervention with the use of a rapid desensitization program (rdp) as a preventive measure should be introduced before initiating pomalidomide. Such a proactive measure for the patient's safety will ensure a smooth transition into pomalidomide treatment. A hsr can be either related or non-related to immunoglobulin E. As imids become an essential treatment backbone for myeloma and other plasma-cell diseases, an increasing number of patients could experience skin and other life-threatening toxicities, resulting in unnecessary discontinuation of these life-prolonging agents. An extemporaneously prepared pomalidomide suspension developed at our centre enables patients to undergo rdp safely. Patients enjoy a good quality of life and clinical response after the rdp procedure.

Abstract
BACKGROUND Venous thromboembolism (vte) is a recognized complication in patients treated with asparaginase-containing chemotherapy regimens; the optimal preventive strategy is unclear. We assessed the safety and efficacy of prophylaxis using low-dose low molecular weight heparin in adult patients with acute lymphoblastic leukemia in complete remission treated with an asparaginase-based post-remission chemotherapy regimen. METHODS As part of the intensification phase of the Dana-Farber Cancer Institute 91-01 regimen, asparaginase was administered weekly to 41 consecutive patients for 21-30 weeks; these patients also received prophylaxis with enoxaparin 40 mg daily (60 mg for patients ≥80 kg). Outcomes were assessed against outcomes in a comparable cohort of 99 patients who received the same chemotherapy regimen without anticoagulation prophylaxis. RESULTS The overall rate of symptomatic venous thrombosis was not significantly different in the prophylaxis and non-prophylaxis cohorts (18.92% and 21.74% respectively). Among patients receiving prophylaxis, vte occurred in higher proportion in those who weighed at least 80 kg (42.86% vs. 4.35%, p = 0.0070). No major bleeding complications occurred in the prophylaxis group (minor bleeding: 8.1%). CONCLUSIONS Prophylaxis with low-dose enoxaparin during the intensification phase was safe, but was not associated with a lower overall proportion of vte.

Abstract
BACKGROUND Keratoconjunctivitis sicca from chronic graft-versus-host disease (cgvhd) after allogeneic stem cell transplantation is common, leading to severe corneal damage and blindness if not treated. We retrospectively examined the efficacy and safety of pooled human albumin eye drops (haeds) for symptom relief in 40 stem-cell transplantation patients after other alternatives had failed. METHODS The Common Terminology Criteria for Adverse Events (version 4.0) and the cgvhd grading scale were used to compare response in the patients during January 2000 and July 2013. In addition, on days 1 and 30, the haeds were subjected to quality assurance testing for sterility, oncotic pressure, albumin measurement, viscosity, pH, and purity by protein electrophoresis. RESULTS Use of haeds resulted in symptom relief for 37 patients (92.5%); 3 patients (7.5%) failed to improve with use of haeds (p ≤ 0.0001). Of the 37 patients having symptom relief, 7 (19%) improved from grade 3 to no dry eye symptoms. Proportionately, post-treatment symptom improvement by two grade levels, from 3 to 1 (70%), was significantly higher than improvement by one grade level, from 3 to 2 (11%) or from 2 to 1 (19%, p ≤ 0.0001). Time to symptom relief ranged from 2 weeks to 28 weeks. Of the 40 patients, 38 (95%) had no adverse reactions. Days 1 and 30 quality assurance testing results were equivalent. CONCLUSIONS Complications of keratoconjunctivitis sicca were well managed and well tolerated with haeds when other remedies failed. Quality assurance testing confirmed that haeds were safe and stable in extreme conditions.

Abstract
322 Background: Therapeutic strategies for colorectal cancer (CRC) patients with synchronous liver metastases are still indeterminate; therefore, we conducted a phase II multicenter trial of neoadjuvant chemotherapy mFOLFOX6 combined with bevacizumab for resectable synchronous liver metastases after R0-resections of primary CRCs. This study was started in June 2008. This is the interim report. Purpose: The aim of this interim analysis is to evaluate the response rate (RR) and adverse events (AEs) of the enrolled patients. Methods: Eligibility criteria included CRC patients with 10 or less synchronous liver metastases that were preoperatively diagnosed as surgically resectable. 20 of the enrolled patients received 8 courses of mFOLFOX6 with bevacizumab, but bevacizumab was omitted at the initial and the final courses, to avoid the AEs at the operations. The primary endpoint was the RR. Results: Among the 20 patients, one patient was excluded from the study because the assumed metastasis was diagnosed to be hemangioma later with the MRI imaging. RR was analyzed for the 19 patients, and AEs were analyzed for the 20 patients. Complete response and partial response were achieved in 2 (10.5%) and 11 (57.9%), respectively (RR: 68.4%); 4 (21.1%) were stable disease, and 2 (10.5%) were progressive disease. The RR was higher than the prespecified boundary; therefore, this study was scheduled to be continued. AEs were the following: neutropenia, hypertension, anemia, leucopenia, nausea, appetite loss, stomatitis, bleeding and proteinuria. Grade 3 neutropenia occurred in 4 cases (20.0%), and sensory neuropathy, stomatitis, diarrhea, and cerebral infarctions occurred in each one (5.0%) of the patients. There was no AE of grade 4 or 5. Liver resections were performed in 17 cases, and R0-resection was achieved in all of the operable cases (R0 rate was 85%). Conclusions: Neoadjuvant chemotherapy mFOLFOX6 combined with bevacizumab appears to be effective and well tolerated. The study is continued as scheduled, to further evaluate the benefit of this regimen. No significant financial relationships to disclose.

Abstract
Schnitzler's syndrome is a rare disorder of unknown aetiology characterized by a chronic urticarial eruption, intermittent fever and monoclonal gammopathy. We encountered an interesting patient with this syndrome, who had been misdiagnosed for 10 years as having Sweet's syndrome because of the histopathological picture, which was a prominent perivascular and interstitial neutrophilic infiltrate in the dermis with leucocytoclasia but without vasculitis. An urticarial eruption with this histopathological feature has recently been categorized as neutrophilic urticarial dermatosis, and it is strongly indicative of an associated systemic disease, mainly Schnitzler's syndrome and other inflammatory diseases. We therefore need to be cautious not to confuse Schnitzler's syndrome with Sweet's syndrome. Further, the serum interleukin (IL)-6 levels, but not those of other cytokines and chemokines, correlated with the disease activity in our patient, suggesting that IL-6 may be involved in some of the disease processes, including neutrophil infiltration.

Abstract
A rare case of mucinous adenocarcinoma of the cecum in a pregnant woman is described. A 32-year-old Korean woman was diagnosed as having an abdominal tumor immediately after giving birth. Abdominal computed tomography demonstrated a smooth mass measuring 10 cm in diameter on the right side of the abdomen. Acute abdomen developed 3 days after birth. At emergency surgery, volvulus of a polypoid tumor was detected at the cecum apart from the normal appendix. We successfully performed a tumorectomy; however, histopathological examination demonstrated mucinous adenocarcinoma with a massive blood clot.

Abstract
OBJECTIVE IL-19 is a novel cytokine of the IL-10 family. In this study, we sought to examine whether IL-19 plays a role in the pathogenesis of RA. METHODS Expression of IL-19, IL-20 receptor 1 (IL-20R1) and IL-20R2 was examined by RT-PCR and immunohistochemical analysis in rheumatoid synovium. The effects of IL-19 on synovial cells established from rheumatoid synovium (RASCs), with regard to IL-6 production and signal transducers and activators of transcription3 (STAT3) activation, were examined by ELISA and western blot analysis, respectively. The effect of IL-19 on RASC apoptosis was examined by Hoechst staining, flow cytometry analysis of annexin V binding and caspase-3 activity. RESULTS IL-19, IL-20R1 and IL-20R2 mRNA were detected by RT-PCR in synovial tissues from RA patients. Immunohistochemical analysis showed IL-19 was predominantly expressed in the hyperplastic lining layers of RA synovial tissues. The majority of IL-19-positive cells were vimentin-positive and CD68-positive synovial cells, serving as markers of fibroblasts and macrophages, respectively. IL-20R1 and IL-20R2 (IL-20Rs) were expressed in both the lining and sublining layers of RA synovium. In RASC, IL-19 was induced by lipopolysaccharide stimulation and constitutive expression of IL-20Rs was observed, suggesting IL-19 has an autocrine action. In terms of this function, IL-19 induced STAT3 activation and increased IL-6 production by RASC above the medium control. Moreover, IL-19 significantly reduced RASC apoptosis induced by serum starvation. CONCLUSIONS These data suggest that IL-19, produced by synovial cells, promotes joint inflammation in RA by inducing IL-6 production and decreasing synovial cell apoptosis.

Abstract
We have isolated a lipase-overproducing mutant, GE14, from Serratia marcescens 8000 after three rounds of N-methyl-N'-nitro-N-nitrosoguanidine mutagenesis. The mutant GE14 produced 95 kU/ml of extracellular lipase in the lipase medium, which was about threefold higher than that of produced by the original strain 8000. Enzymatic characteristics including specific activity of purified lipases from culture supernatants of GE14 and 8000 were almost same. The lipase gene (lipA) of GE14 contained two base substitutions; one in the promoter region and another in the N-terminal region of the lipA gene without an amino acid substitution. Promoter analysis using lipA-lacZ fusion plasmids revealed that these substitutions were responsible for the increase in the lipA expression level, independently. In contrast, no base substitution was found in the genes encoding the lipase secretion device, the Lip system. In addition, the genes coding for metalloprotease and the cell surface layer protein which are both secreted through the Lip system and associated with extracellular lipase production, also contained no base substitution. The strain GE14 carrying a high-copy-number lipA plasmid produced a larger amount of the extracellular lipase than the recombinant strains of 8000 and other mutants also did, indicating that GE14 was not only a lipase-overproducing strain, but also an advantageous host strain for overproducing the lipase by a recombinant DNA technique. These results suggest that the lipase-overproducing mutant GE14 and its recombinant strains are promising candidates for the industrial production of the S. marcescens lipase.

Abstract
A search for a nonzero neutrino magnetic moment has been conducted using 1496 live days of solar neutrino data from Super-Kamiokande-I. Specifically, we searched for distortions to the energy spectrum of recoil electrons arising from magnetic scattering due to a nonzero neutrino magnetic moment. In the absence of a clear signal, we found micro(nu)</=(3.6x10(-10))micro(B) at 90% C.L. by fitting to the Super-Kamiokande day-night spectra. The fitting took into account the effect of neutrino oscillation on the shapes of energy spectra. With additional information from other solar neutrino and KamLAND experiments constraining the oscillation region, a limit of micro(nu)</=(1.1x10(-10))micro(B) at 90% C.L. was obtained.

Abstract
AIMS To determine the prevalence of enterotoxin-producing Staphylococcus intermedius in dogs and pigeons. METHODS AND RESULTS A total of 106 S. intermedius isolates from 44 dogs and 62 pigeons were tested for the production of enterotoxins A, B, C and D by reverse passive latex agglutination (RPLA) and for sec-canine by PCR. Only one isolate from dog was positive for SEC and sec-canine. Screening of sec-canine-negative strains by nested PCR led to the identification of a novel enterotoxin-related gene, se-int. SE-int showed a significant homology (59-61% identity) with SEC and (56.6% identity) SEB. All 44 isolates from dogs and five isolates (8.1%) from pigeons were se-int positive. CONCLUSIONS While S. intermedius was isolated more frequently from pigeons than from dogs, se-int was more prevalent among the S. intermedius isolates from dogs, compared with the pigeon isolates. SIGNIFICANCE AND IMPACT OF THE STUDY Further characterization of the se-int-positive S. intermedius strains should clarify their pathogenic potential including enterotoxigenicity and zoonotic transmissibility to human beings.

Abstract
We present the results of a search for low energy nu(e) from the Sun using 1496 days of data from Super-Kamiokande-I. We observe no significant excess of events and set an upper limit for the conversion probability to nu(e) of the 8B solar neutrino. This conversion limit is 0.8% (90% C.L.) of the standard solar model's neutrino flux for total energy=8-20 MeV. We also set a flux limit for monochromatic nu(e) for E(nu(e))=10-17 MeV.

Abstract
A search for the relic neutrinos from all past core-collapse supernovae was conducted using 1496 days of data from the Super-Kamiokande detector. This analysis looked for electron-type antineutrinos that had produced a positron with an energy greater than 18 MeV. In the absence of a signal, 90% C.L. upper limits on the total flux were set for several theoretical models; these limits ranged from 20 to 130 macro nu(e) cm(-2) s(-1). Additionally, an upper bound of 1.2 macro nu(e) cm(-2) s(-1) was set for the supernova relic neutrino flux in the energy region E(nu)>19.3 MeV.

Abstract
The K2K experiment observes indications of neutrino oscillation: a reduction of nu(mu) flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are observed in Super-Kamiokande (SK), 250 km from the neutrino production point, with an expectation of 80.1(+6.2)(-5.4). Twenty-nine one ring mu-like events are used to reconstruct the neutrino energy spectrum, which is better matched to the expected spectrum with neutrino oscillation than without. The probability that the observed flux at SK is explained by statistical fluctuation without neutrino oscillation is less than 1%.
