Abstract
Background Hemorrhagic meningiomas are rare. We report a rare case of nontraumatic convexity and interhemispheric acute subdural hematoma (ASDH) caused by a falx meningioma. Case Description An 84-year-old woman with a history of atrial fibrillation and hypertension who was taking warfarin presented to our emergency department with a sudden disorder of consciousness. The patient had no traumatic events associated with her symptoms. Computed tomography (CT) revealed right convexity and interhemispheric ASDH, mass lesions in the left frontal lobes, and brain herniation. Contrast-enhanced CT revealed vascular structures within the mass lesion. CT angiography (CTA) revealed no aneurysm or arteriovenous malformation, and the venous phase revealed occlusion in the anterior portion of the superior sagittal sinus. The patient had her right convexity and interhemispheric ASDH removed endoscopically. A mass lesion located on the falx, which was easily bleeding, soft, and suctionable, was immediately detected. Histopathological examination revealed fibrous meningioma, a benign meningioma of the World Health Organization grade 1. Despite undergoing aggressive treatment, the patient's general condition deteriorated. Conclusion Hemorrhagic meningiomas can easily be missed with plain CT, and the enhancement effect of CTA and tumor shadow on digital subtraction angiography may not be observed during the acute phase. Surgery for nontraumatic ASDH should be performed considering the possibility that a meningioma causes it.

Abstract
BackgroundSince the goals of remission or low disease activity are becoming more realistic with advances in treatment for SLE, there is a need to examine the measurements for SLE especially in patients with low disease activity. It has been known that disease activities in SLE are correlated with anti-DNA antibodies (Abs). However, it was not clear which measurements of disease activities or patient reported outcomes correlate better with anti-DNA Abs.ObjectivesTo examine the association between parameters for SLE and anti-DNA Abs measured with RIA in Kyoto Lupus Cohort, a SLE registry in Kyoto University Hospital from 2019 to 2021.Methods1)Correlations between anti-DNA Abs with SLEDAI, M-SLEDAI (SLEDAI without anti-DNA Abs), VAS, LupusPRO, SF-36, and Systemic lupus erythematosus Symptom Checklist (SSC) were evaluated cross-sectionally (n = 310).2)The alterations in SLE parameters and anti-DNA Abs between two visits were examined (n = 106). Further, the correlations within 3 months were examined in cases with flare-ups of SLE (the alteration in SLEDAI > 0 and anti-DNA Abs≧0, n = 39). The associations of the alterations of anti-DNA Abs with each item of SLEDAI classified by organs were also examined.Results1)31 percent of the cases in the entire registry was classified as remission or low disease activity (Table 1). SLEDAI (mean±SD) was higher in patients positive for anti-DNA Abs (7.94±5.20) than that in patients negative for anti-DNA Abs (4.56±4.65) (p < 0.0001). Anti-DNA Abs were weakly correlated with SLEDAI (R = 0.24 [p < 0.0001]), M-SLEDAI (R = 0.15 [p = 0.014]), and Physician-VAS (R = 0.19 [p = 0.0016]). On the other hand, there were no significant correlations between anti-DNA Abs and LupusPRO and SSC. Some dimensions in SF-36 had weak correlations with anti-DNA Abs, while no component summary scores had significant correlations with anti-DNA Abs.Table 1.Patients’ demographics and disease characteristics in the cohort (n = 310).VariableResultsAge (years)47.7 (39.4, 57.5)Female sexn = 284 (91.6%)Disease duration (years)15.9 (9.4, 24.5)Anti-DNA Ab positivity†n = 106 (34.2%)Anti- DNA Ab titer (U/mL)4 (0, 8)SLEDAI4 (2, 8)SLEDAI<=4n = 162 (52.1%)SSC31 (16.2, 52.5)Remission or LDAn = 95 (30.7%)Patient-VAS38 (15, 52)Physician-VAS13.3 (3.3, 23.3)SF-36 PCS45.4 (36.6, 52.4)SF-36 MCS48.2 (41.5, 53.6)SF-36 RCS51.3 (42.6, 58.6)LupusPRO HQOL70.2 (54.8, 86.5)LupusPRO NHQOL41.7 (31.3, 51.0)Glucocorticoid (mg/day)5 (4, 8)* Data are n (%) or median (Q1, Q3).† Anti-DNA Ab positivity at the time of the cross-sectional observation.2)No significant correlations were observed between the alterations of SLEDAI and anti-DNA Abs (R = 0.00 [95% CI: -0.23 – 0.22, p = 0.95]) in the total of patients with various range of observation periods (Figure 1A). In contrast, a significant correlation was observed (R = 0.32, p = 0.04) within 3 months after the flare-ups of SLE (Figure 1B). No significant correlations were found between the alterations in VAS and anti-DNA Abs, or the alterations of SSC and anti-DNA Abs. They showed the following organ symptoms: renal involvement, 62.8%; musculoskeletal, 17.1%; neuropsychiatric, 11.4%; hematological, 5.7%; mucocutaneous, 11.4%; serositis, 2.9%, and fever, 2.9%.Figure 1.The associations between the alteration in anti-DNA Ab and SLEDAIConclusionThe associations between anti-DNA Abs with several parameters of SLE were examined. Anti-DNA Abs correlated with disease activities (SLEDAI) in SLE patients, especially when observed in the condition of flare-up.References[1]Ho A, et al.

Abstract
A multi-energy soft x-ray pinhole camera has been designed, built, and deployed at the Madison Symmetric Torus to aid the study of particle and thermal transport, as well as MHD stability physics. This novel imaging diagnostic technique employs a pixelated x-ray detector in which the lower energy threshold for photon detection can be adjusted independently on each pixel. The detector of choice is a PILATUS3 100 K with a 450 μm thick silicon sensor and nearly 100 000 pixels sensitive to photon energies between 1.6 and 30 keV. An ensemble of cubic spline smoothing functions has been applied to the line-integrated data for each time-frame and energy-range, obtaining a reduced standard-deviation when compared to that dominated by photon-noise. The multi-energy local emissivity profiles are obtained from a 1D matrix-based Abel-inversion procedure. Central values of Te can be obtained by modeling the slope of the continuum radiation from ratios of the inverted radial emissivity profiles over multiple energy ranges with no a priori assumptions of plasma profiles, magnetic field reconstruction constraints, high-density limitations, or need of shot-to-shot reproducibility. In tokamak plasmas, a novel application has recently been tested for early detection, 1D imaging, and study of the birth, exponential growth, and saturation of runaway electrons at energies comparable to 100 × Te,0; thus, early results are also presented.

Abstract
Background:Systemic lupus erythematosus (SLE) is an autoimmune disease that can not only cause systemic symptoms, such as fever and arthritis, but can also damage important organs, such as those of the central nervous system and the kidneys. Prevention of irreversible organ damage is important for better prognosis [1]. Additionally, the importance of maintaining the quality of life (QOL) of patients has recently been emphasized. However, only a few studies have examined the relationship between irreversible organ damage and patient QOL.Objectives:To assess the relationship between organ damage and QOL, and to survey which organs have more significant effects on QOL.Methods:We conducted a questionnaire-based survey of 183 patients with SLE at Kyoto University Hospital from September to December 2019. We used the SLICC/ACR Damage Index (SDI) to evaluate organ damage [2]. The following five scales were employed to evaluate QOL: the physical (PCS) and mental component summary (MCS) of the Medical Outcome Study (MOS) 36-Item Short-Form Health Survey version 2.0 (SF-36v2) [3], health (HRQOL) and non-health-related QOL (N-HRQOL) of LupusPRO [4], and SLE Symptom Checklist (SSC) [5].Results:Linear regression analysis showed significant correlation between the SDI score and all QOL scales except for N-HRQOL, suggesting negative effects of organ damage on QOL (Table 1). Next, we analysed whether there was a significant difference in the SF-36 score between those who were positive and negative for each SDI item (41 in total), using the Wilcoxon rank sum test. Muscle atrophy or weakness (p= 3.0×10-10), osteoporosis with fracture or vertebral collapse (p= 9.7×10-8), claudication (p= 7.4×10-5), and cognitive impairment or major psychosis (p= 9.9×10-5) significantly correlated (p< 1.2×10-3) with PCS, and scarring chronic alopecia (p= 3.4×10-4) with MCS (Table 2). In addition, the five SDI items significantly correlated with the remaining three QOL scales (HRQOL, N-HRQOL, and SSC;p< 0.05).Table 1.Relationship between the SDI score and QOLSF-36LupusPROSSCPCSMCSHRQOLN-HRQOLp-value<2.0×10-161.7×10-32.2×10-110.231.9×10-8Table 2.Relationship between each SDI item and the SF-36 score (p< 1.2×10-3SDI itemPCS scorep-valuePositive(Median (IQR))Negative(Median (IQR))Muscle atrophy/weakness33 (19-45)50 (43-54)3.0×10-10Osteoporosis with fracture/vertebral collapse24 (12-32)49 (38-54)9.7×10-8Claudication31 (19-35)49 (38-54)7.4×10-5Cognitive impairment/psychosis27 (17-33)49 (38-54)9.9×10-5SDI itemMCS scorep-valuePositive(Median (IQR))Negative(Median (IQR))Scarring chronic alopecia42 (29-51)49 (39-54)3.4×10-4Conclusion:We demonstrated that organ damage has negative effects on patient QOL, indicating the importance of preventing irreversible organ damage for maintaining QOL. Moreover, muscle atrophy/weakness, osteoporosis with fracture/vertebral collapse, claudication, cognitive impairment/major psychosis, and scarring chronic alopecia significantly correlated with QOL deterioration, suggesting that these items should be examined with special care in clinical practice.References:[1]Lopez R, et al.

Abstract
In this study, dogs with atopic dermatitis were separated into non-food-induced atopic dermatitis (NFIAD) group (n = 15) and food-induced atopic dermatitis (FIAD) group (n = 37) based on an elimination diet test. IgE reactivity for crude Malassezia pachydermatis (M. pachydermatis) and house dust mites (HDM) allergen extracts was investigated in the two groups using fluorometric enzyme-linked immunosorbent assay (ELISA) and intradermal skin test (IDST). Nine (60%) of the 15 dogs in NFIAD group and 6 (16%) of the 37 dogs in FIAD group showed specific IgE for M. pachydermatis (Mann-Whitney U-test, P < 0.01). By immunoblotting analysis, the pooled serum samples from dogs with IgE for M. pachydermatis showed IgE reactivity for 50 kDa protein of M. pachydermatis. Twelve (80%) of the 15 dogs in NFIAD group and 8 (22%) of the 37 dogs in FIAD group showed specific IgE for HDM (Mann-Whitney U-test, P < 0.01). In addition, the dogs in NFIAD group significantly show a positive IDST to M. pachydermatis and HDM extracts compared with the dogs in FIAD group. The results suggest that dogs with NFIAD are at increased risk of becoming sensitized to the normal commensal organism M. pachydermatis compared with dogs with FIAD, perhaps co-sensitization occurred due to an HDM protease antigen's, Der f 1 and/or Der p 1, proteolytic activity related epidermal skin barrier defects. Treatment to limit skin colonization may thus be especially important in NFIAD.

Abstract
A new tool has been developed to calculate the spectral, spatial, and temporal responses of multi-energy soft x-ray (ME-SXR) pinhole cameras for arbitrary plasma densities (n e,D), temperature (T e), and impurity densities (n Z). ME-SXR imaging provides a unique opportunity for obtaining important plasma properties (e.g., T e, n Z, and Z eff) by measuring both continuum and line emission in multiple energy ranges. This technique employs a pixelated x-ray detector in which the lower energy threshold for photon detection can be adjusted independently. Simulations assuming a tangential geometry and DIII-D-like plasmas (e.g., n e,0 ≈ 8 × 1019 m-3 and T e,0 ≈ 2.8 keV) for various impurity (e.g., C, O, Ar, Ni, and Mo) density profiles have been performed. The computed brightnesses range from few 102 counts pixel-1 ms-1 depending on the cut-off energy thresholds, while the maximum allowable count rate is 104 counts pixel-1 ms-1. The typical spatial resolution in the mid-plane is ≈0.5 cm with a photon-energy resolution of 500 eV at a 500 Hz frame rate.

Abstract
A multi-energy soft x-ray pinhole camera has been designed and built for the Madison Symmetric Torus reversed field pinch to aid the study of particle and thermal-transport, as well as MHD stability physics. This novel imaging diagnostic technique combines the best features from both pulse-height-analysis and multi-foil methods employing a PILATUS3 x-ray detector in which the lower energy threshold for photon detection can be adjusted independently on each pixel. Further improvements implemented on the new cooled systems allow a maximum count rate of 10 MHz per pixel and sensitivity to the strong Al and Ar emission between 1.5 and 4 keV. The local x-ray emissivity will be measured in multiple energy ranges simultaneously, from which it is possible to infer 1D and 2D simultaneous profile measurements of core electron temperature and impurity density profiles with no a priori assumptions of plasma profiles, magnetic field reconstruction constraints, high-density limitations, or need of shot-to-shot reproducibility. The expected time and space resolutions will be 2 ms and <1 cm, respectively.

Abstract
INTRODUCTION The current study aimed to compare cytology using SurePath® (SP)-LBC and biliary tissue histology (BTH) for the diagnosis of biliary disease. METHODS Between January 2014 and December 2016, 57 patients underwent endoscopic retrograde cholangiopancreatography for the diagnosis of biliary disease. Biliary cytological samples were processed using SP-LBC and subsequently BTH was performed. A final diagnosis was confirmed by surgery (23 malignant cases) and clinical follow-up (34 benign and malignant cases): 18 extrahepatic cholangiocarcinoma; 17 intrahepatic/hilar cholangiocarcinoma (intra/H-CC); eight other malignant disease; and 14 benign biliary disease. The diagnoses made using SP-LBC and BTH were classified into four categories: (1) benign; (2) indeterminate; (3) suspicious for malignancy/malignant; and (4) inadequate. In addition, diagnostic accuracy was compared between SP-LBC and BTH. RESULTS Although 23% (13/57) of BTH samples were classified as inadequate, all SP-LBC cases were classified as adequate. Among 43 malignant cases, 11 normal, four indeterminate and 28 suspicious for malignancy/malignant were found using SP-LBC (26%, 9% and 65%, respectively), in contrast to 10 inadequate, nine normal, 10 indeterminate and 14 suspicious for malignancy/malignant observed using BTH (23%, 21%, 23%, and 33%, respectively). The identification of malignant cells was strikingly different between SP-LBC and BTH. Furthermore, limited to intra/H-CC, accuracy was significantly higher using SP-LBC than using BTH (P < .001). CONCLUSIONS SP-LBC of the biliary tract is a useful and reliable method for diagnosing biliary malignant disease and has an advantage over BTH for detecting malignant cells and accurately diagnosing intra/H-CC.

Abstract
INTRODUCTION The aim of this study was to examine whether a combined test using both cell sediment and supernatant cytology cell-free DNA (ccfDNA) is more useful in detecting EGFR mutation than using cell sediment DNA or supernatant ccfDNA alone in pleural effusion of lung cancer patients. METHODS A total of 74 lung adenocarcinoma patients with paired samples between primary tumour and corresponding metastatic tumour with both cell sediment and supernatant ccfDNA of pleural effusion cytology were enrolled in this study. Cell sediment and supernatant ccfDNA were analysed separately for EGFR mutations by polymerase chain reaction. RESULTS Out of 45 patients with mutant EGFR in primary tumours, EGFR mutations were detected in 23 cell sediments of corresponding metastases (sensitivity; 51.1%) and 20 supernatant ccfDNA corresponding metastases (sensitivity; 44.4%). By contrast, the combined test detected EGFR mutations in 27 corresponding metastases (sensitivity; 60.0%), and had a higher sensitivity than the cell sediment or the supernatant ccfDNA alone (P < .05). Out of 45 patients with mutant EGFR, 24, three and 18 were cytologically diagnosed as positive, atypical or negative, respectively. The detection rate in the combined test was highest (95.8%) in the positive group, and mutant EGFR was also detected in four of 18 samples (22.2%) in the negative group. CONCLUSIONS A combined test using both cell sediment DNA and supernatant ccfDNA samples increases the concordance rate of EGFR mutations between primary tumour and corresponding metastases. Our findings indicate that supernatant ccfDNA is useful even in cases where the cytological diagnosis is negative.

Abstract
After several experimental campaigns in the Kyushu University Experiment with Steady-state Spherical Tokamak (QUEST), the originally stainless steel plasma-facing wall (PFW) becomes completely covered with a deposited film composed of mixture materials, such as iron, chromium, carbon, and tungsten. In this work, an innovative colorimetry-based method was developed to measure the thickness of the deposited film on the actual QUEST wall. Because the optical constants of the deposited film on the PFW were position-dependent and the extinction coefficient k1 was about 1.0-2.0, which made the probing light not penetrate through some thick deposited films, the colorimetry method developed can only provide a rough value range of thickness of the metal-containing film deposited on the actual PFW in QUEST. However, the use of colorimetry is of great benefit to large-area inspections and to radioactive materials in future fusion devices that will be strictly prohibited from being taken out of the limited area.

Abstract
This paper evaluates the accuracy of electron temperature measurements and relative transmissivities of double-pass Thomson scattering diagnostics. The electron temperature (Te) is obtained from the ratio of signals from a double-pass scattering system, then relative transmissivities are calculated from the measured Te and intensity of the signals. How accurate the values are depends on the electron temperature (Te) and scattering angle (θ), and therefore the accuracy of the values was evaluated experimentally using the Large Helical Device (LHD) and the Tokyo spherical tokamak-2 (TST-2). Analyzing the data from the TST-2 indicates that a high Te and a large scattering angle (θ) yield accurate values. Indeed, the errors for scattering angle θ = 135° are approximately half of those for θ = 115°. The method of determining the Te in a wide Te range spanning over two orders of magnitude (0.01-1.5 keV) was validated using the experimental results of the LHD and TST-2. A simple method to provide relative transmissivities, which include inputs from collection optics, vacuum window, optical fibers, and polychromators, is also presented. The relative errors were less than approximately 10%. Numerical simulations also indicate that the Te measurements are valid under harsh radiation conditions. This method to obtain Te can be considered for the design of Thomson scattering systems where there is high-performance plasma that generates harsh radiation environments.

Abstract
BACKGROUND Cry j 2 and Cha o 2 are major allergens in Japanese cedar (Cryptomeria japonica; CJ) and Japanese cypress (Chamaecyparis obtusa; CO) pollen, respectively. Here, we assessed the epitopes related to the cross-reactivity between Cry j 2 and Cha o 2 using in vitro analyses. METHODS Peptides were synthesized based on Cry j 2 sequential epitopes and relevant Cha o 2 amino acid sequences. Four representative monoclonal antibodies (mAbs) against Cry j 2 were used according to their epitope recognitions. Serum samples were collected from 31 patients with CJ pollinosis. To investigate cross-reactivity between Cry j 2 and Cha o 2, ELISA and inhibition ELISA were performed with mAbs and sera from patients with CJ pollinosis. RESULTS Two of four mAbs had reactivity to both Cry j 2 and Cha o 2. Of these two mAbs, one mAb (T27) recognized the amino acid sequence (169)KVVNGRTV(176) on Cha o 2. This is related to the core epitope (169)KWVNGREI(176) on Cry j 2, which is an important IgE epitope. In addition, we found that these correlative sequences and purified allergens showed cross-reactivity between Cry j 2 and Cha o 2 in IgE of CJ patients. CONCLUSIONS We demonstrated the importance of (169)KVVNGRTV(176) in Cha o 2 for cross-reactivity with the Cry j 2 epitope (169)KWVNGREI(176), which plays an important role in allergenicity in CJ pollinosis. Our results are useful for the development of safer and more efficient therapeutic strategies for the treatment of CJ and CO pollen allergies.

Abstract
In TST-2 Ohmic discharges, local current is measured using a Rogowski probe by changing the angle between the local magnetic field and the direction of the hole of the Rogowski probe. The angular dependence shows a peak when the direction of the hole is almost parallel to the local magnetic field. The obtained width of the peak was broader than that of the theoretical curve expected from the probe geometry. In order to explain this disagreement, we consider the effect of sheath in the vicinity of the Rogowski probe. A sheath model was constructed and electron orbits were numerically calculated. From the calculation, it was found that the electron orbit is affected by E × B drift due to the sheath electric field. Such orbit causes the broadening of the peak in the angular dependence and the dependence agrees with the experimental results. The dependence of the broadening on various plasma parameters was studied numerically and explained qualitatively by a simplified analytical model.

Abstract
A Rogowski probe consisting of a small multi-layer Rogowski coil, five magnetic pick-up coils, and a Langmuir probe was developed to measure the local current density and its direction. It can be moved along the major radius and can be turned around its axis. This probe was used to measure the current density profile near the last closed flux surface of Ohmic plasmas in Tokyo Spherical Tokamak-2. The current density profile was measured successfully with a signal to noise ratio of greater than 20.

Abstract
The multi-pass Thomson scattering (TS) scheme enables obtaining many photons by accumulating multiple TS signals. The signal-to-noise ratio (SNR) depends on the accumulation number. In this study, we performed multi-pass TS measurements for ohmically heated plasmas, and the relationship between SNR and the accumulation number was investigated. As a result, improvement of SNR in this experiment indicated similar tendency to that calculated for the background noise dominant situation.

Abstract
In multi-pass Thomson scattering (TS) scheme, a laser pulse makes multiple round trips through the plasma, and the effective laser energy is enhanced, and we can increase the signal-to-noise ratio as a result. We have developed a coaxial optical cavity in which a laser pulse is confined, and we performed TS measurements using the coaxial cavity in tokamak plasmas for the first time. In the optical cavity, the laser energy attenuation was approximately 30% in each round trip, and we achieved a photon number gain of about 3 compared with that obtained in the first round trip. In addition, the temperature measurement accuracy was improved by accumulating the first three round trip waveforms.

Abstract
A 73-year-old Japanese woman was hospitalized for detailed examination of nausea, diarrhea and loss of appetite. Atypical erosion in the ileum was found on endoscopy. Biopsy of this erosion showed proliferation of cells containing numerous Russell bodies. Differential diagnoses considered were Russell body enteritis, crystal-storing histiocytosis, Mott cell tumor, immunoproliferative small intestinal disease (IPSID) and mucosa-associated lymphoid tissue (MALT) lymphoma. The cells containing prominent Russell bodies showed diffuse positivity for CD79a and CD138, but negative results for CD20, CD3, UCHL-1, CD38 and CD68. Russell bodies were diffusely positive for lambda light chain, but negative for kappa light chain, and immunoglobulin (Ig) G, IgA and IgM. Based on these findings, Russell body enteritis, crystal-storing histiocytosis and IPSID were ruled out. As the tumor formed no mass lesions and was restricted to the gastrointestinal tract, MALT lymphoma with extensive plasma cell differentiation was finally diagnosed. The patient showed an unexpectedly aggressive clinical course. The number of atypical lymphocytes in peripheral blood gradually increased and T-prolymphocytic leukemia (T-PLL) emerged. The patient died of T-PLL 7 mo after admission. Autopsy was not permitted.

Abstract
The surgical strategy for gallbladder cancer (GBC) depends on the extent of the disease. Thus, the identification of useful prognostic markers exerting strong prognostic impact for each T stage would be beneficial in the development of rational therapeutic strategies. The purpose of this study was to identify useful prognostic markers of GBC for each T stage. CD8+ tumor-infiltrating lymphocytes (TIL), Ki-67 labeling index (LI), p53 nuclear expression and mitotic count (MC) were investigated as candidate prognostic markers. In total, 86 patients with invasive GBC were included. Of the prognostic markers examined, only MC showed a correlation with reduced survival (P=0.0383) in the univariate analysis of overall T stage. In the univariate analysis of T2 stage (n=31), only high p53 expression correlated with survival showing a positive correlation (P=0.0154). In the univariate analysis of T3 stage (n=40), the only factor showing a significant correlation with survival was MC (P=0.0113). Multivariate analysis, including N and M as factors, identified only MC as an independent prognostic factor in T3 stage GBC (P=0.0419). In conclusion, this study demonstrated the strong prognostic impact of MC in GBC, particularly in patients with T3 tumor.

Abstract
OBJECTIVE The wall-carving (WC) imaging technique is used to evaluate early gastric cancer using multidetector row computed tomography (MDCT) image data for only the arterial phase. Our purpose was to investigate if WC images derived from portal phase MDCT images can enhance the visualization of early gastric cancer. SUBJECTS AND METHODS Fourteen consecutive patients (average age/age range (years) = 75.8/61 to 86; male/female = 9/5) were enrolled. They were diagnosed with early gastric cancer and underwent contrast-enhanced MDCT before treatment. WC images of the arterial and portal phases were created from images scanned by 64-detector-row MDCT 40 and 60 seconds after the initiation of the contrast material injection, respectively. The correlation between the detection rates of lesions in the WC images and pathological findings was investigated. RESULTS Totals of 71.4% (10/14) of arterial phase WC images and 71.4% (10/14) of portal phase WC images showed lesions. The imaging ability improved to 85.7% (12/14) when the two sets of images were combined. Well-differentiated adenocarcinomas tended to be visualized better in WC images of any phases. CONCLUSION WC is an excellent image analysis technique for visualizing early gastric cancer lesions. The depiction rates were improved by using a combination of arterial and portal WC images. The scan timing after the contrast material injection should be carefully investigated to improve the detection rate of lesions.

Abstract
PURPOSE Japanese cedar (Cryptomeria japonica; CJ) pollinosis is a type I allergy induced by CJ pollen, and Cry j 2 is one of the major allergens in this pollen. In a previous study, we analyzed IgE epitopes on Cry j 2 in humans by using synthetic peptides. The main purpose of this study was to identify B-cell epitopes on Cry j 2 in patients with CJ pollinosis by using monoclonal antibodies (mAbs) for Cry j 2. METHODS We used ELISA with mAbs for the epitope analysis. Sera samples were collected from 80 patients with CJ pollinosis, and allergenic epitopes for mAbs and human IgE were identified using ELISA with synthetic peptides. The importance of the epitopes for human IgE was analyzed using an inhibition ELISA. RESULTS Four independent epitopes (epitope #1, #2, #3, and #4) were identified on Cry j 2 with the use of mAbs. Epitope #3 and #4, corresponding to peptides No. 25 and No. 33, respectively, were newly determined as epitopes for mAbs and human IgE. Inhibition ELISA showed that not only epitope #2 (sequential) but epitope #1 (conformational) may play an important role in the CJ pollinosis. CONCLUSIONS Our results revealed 4 epitopes, including two new ones, on Cry j 2. We also found that inhibition ELISA with appropriate mAbs could be a viable method of evaluating the importance of the conformational and sequential epitopes for human IgE. These results are beneficial for the development of safer and more efficient therapeutic strategies for treating CJ pollinosis.

Abstract
Classical polyarteritis nodosa (cPN) is a rare autoimmune disease featuring systemic inflammation of middle- and small-sized arteries. Because most of autopsy cases underwent clinical treatment, arterial fibrinoid necrosis, which is the most specific finding of cPN, is often obscure. The aim of this study was to seek morphological characteristics of the middle-sized arteries in autopsy cases of cPN, and to identify immunohistochemical markers for the diagnosis of cPN. Nineteen patients who had undergone autopsy with a diagnosis of cPN were enrolled. Twenty-one autopsy cases without cPN were examined as control group. Arterial fibrinoid necrosis in medium-sized arteries was observed in 8/19 autopsy cases. Elastica van Gieson staining showed an increased number of elastic fiber layers (P<0.0001) and greater distances between elastic fiber layers (P<0.0001) in the renal middle-sized arteries of the cPN group. These findings probably reflected the post-inflammatory remodeling process after necrotizing vasculitis. On immunohistochemical examination, the cPN group showed high matrix metalloproteinase-1 and tumor necrosis factor-α expressions and decreased smoothelin expression in the vascular wall compared to the control group. When uncertain or atypical autopsy cases of cPN are examined, these findings can help to make the pathological diagnosis of cPN.

Abstract
Using an 8 × 8 channel photomultiplier tube assembly and a single Czerny-Turner monochromator, we have developed a novel Doppler spectroscopic system which can measure the time evolutions of spectral distribution of plasma emission from eight different lines of sight simultaneously. An optical lens system is employed to couple the output of the monochromator with the detector assembly, resulting in small cross-talks less than 5% in spatial distribution together with large magnification of up to 50 in wavelength direction. The suggested system yields cost-effective polychromatic measurements of eight spatial channels with uniform optical and electrical characteristics.

Abstract
This paper presents an experimental demonstration to determine electron temperature (T(e)) with unknown spectral sensitivity (transmissivity) in a Thomson scattering system. In this method, a double-pass scattering configuration is used and the scattered lights from each pass (with different scattering angles) are measured separately. T(e) can be determined from the ratio of the signal intensities without knowing a real chromatic dependence in the sensitivity. Note that the wavelength range for each spectral channel must be known. This method was applied to the TST-2 Thomson scattering system. As a result, T(e) measured from the ratio (T(e,r)) and T(e) measured from a standard method (T(e,s)) showed a good agreement with <∣T(e,r) - T(e,s)∣∕T(e,s)> = 7.3%.

Abstract
Canine non-rabies combined vaccines are widely used to protect animals from infectious agents, and also play an important role in public health. We performed a large-scale survey to investigate vaccine-associated adverse events (VAAEs), including anaphylaxis, in Japan by distributing questionnaires on VAAEs to veterinary hospitals from April 1, 2006 through May 31, 2007. Valid responses were obtained for 57,300 vaccinated dogs at 573 animal hospitals; we obtained VAAEs information for last 100 vaccinated dogs in each veterinary hospital. We found that of the 57,300, 359 dogs showed VAAEs. Of the 359 dogs, death was observed in 1, anaphylaxis in 41, dermatological signs in 244, gastrointestinal signs in 160, and other signs in 106. Onset of VAAEs was mostly observed within 12 h after vaccination (n = 299, 83.3%). In this study, anaphylaxis events occurred within 60 min after vaccination, and about half of these events occurred within 5 min (n = 19, 46.3%). Furthermore, where anaphylaxis was reported, additional information to support the diagnosis was obtained by reinvestigation. Our resurvey of dogs with anaphylaxis yielded responses on 31 dogs; 27 of these demonstrated collapse (87.1%), 24 demonstrated cyanosis (77.4%), and both signs occurred in 22 (71.0%). Higher rates of animal VAAEs, anaphylaxis, and death were found in Japan than in other countries. Further investigations, including survey studies, will be necessary to elucidate the interaction between death and vaccination and the risk factors for VAAEs, and thus develop safer vaccines. Moreover, it may also be necessary to continually update the data of VAAEs.

Abstract
Arterial spin-labeling (ASL) magnetic resonance imaging (MRI) enables non-invasive acquisition of the brain perfusion information in cerebrovascular disease. We investigated hemodynamic changes in intracranial dural arteriovenous fistulas (DAVFs) using ASL-MRI. ASL-MRI by a Q2TIPS sequence on a 3.0-Tesla MRI was performed for three patients with Cognard's IIa+b type of DAVFs before and after treatment. Perfusion images obtained by ASL-MRI (ASL images) before treatment were visually compared with those by single-photon emission computed tomography images (SPECT images). Increasing rates of temporal changes of regional perfusion values in ASL images (ASL values) before and after treatment were also calculated. In all three patients, ASL images before treatment demonstrated high perfusion in regions around the shunting areas, where normal or low perfusion were detected on SPECT images; thus, ASL images might have demonstrated the abundant arterial shunting flow via the fistulas. On days eight to 20 after treatment, ASL values around the shunt areas remained the same or decreased, and those in the regions other than the shunt areas increased in all three patients. This might have been due to a combination of the following: a decrease in shunt flow volume, an amelioration of venous congestion, and a sustained an upward shift in the autoregulation of the brain perfusion pressure. All regional ASL values decreased on days 112 and 120 after treatment in two patients, which possibly reflects a reduction in the upward shift in autoregulation. ASL-MRI might be useful for identifying the hemodynamic behavior of DAVFs before and after treatment.
