Abstract
When a drop impacts onto a liquid pool, it ejects a thin horizontal sheet of liquid, which emerges from the neck region connecting the two liquid masses. The leading section of this ejecta bends down to meet the pool liquid. When the sheet touches the pool, at an "elbow," it ruptures and sends off microdroplets by a slingshot mechanism, driven by surface tension. High-speed imaging of the splashing droplets suggests the liquid sheet is of submicron thickness, as thin as 300 nm. Experiments in partial vacuum show that air resistance plays the primary role in bending the sheet. We identify a parameter regime where this slingshot occurs and also present a simple model for the sheet evolution, capable of reproducing the overall shape.

Abstract
The peeling of adhesive tape is known to proceed with a stick-slip mechanism and produces a characteristic ripping sound. The peeling also produces light and when peeled in a vacuum, even X-rays have been observed, whose emissions are correlated with the slip events. Here we present direct imaging of the detachment zone when Scotch tape is peeled off at high speed from a solid surface, revealing a highly regular substructure, during the slip phase. The typical 4-mm-long slip region has a regular substructure of transverse 220 μm wide slip bands, which fracture sideways at speeds over 300 m/s. The fracture tip emits waves into the detached section of the tape at ∼ 100 m/s, which promotes the sound, so characteristic of this phenomenon.

Abstract
The purpose of this study was to investigate the minimum effective dose of recombinant canine interferon-gamma (rCaIFN-gamma) for the treatment of dogs with atopic dermatitis (AD). Thirty-four dogs with AD from 17 animal hospitals in Japan were administered half or one-fifth of the approved rCaIFN-gamma dose of 10 000 units/kg, three times a week for 4 weeks, followed by once weekly for an additional 4 weeks. Pruritus, excoriation, erythema and alopecia were evaluated and scored by the investigators on weeks 2, 4, 6, 8 and 12. The efficacy rate (number of excellent cases + number of good cases/total number of cases) at week 8 in the 2000 units/kg group was 36.4% for pruritus, 36.4% for excoriation, 45.5% for erythema and 36.4% for alopecia. In contrast, in the 5000 units/kg group, the efficacy rate was 64.3% for pruritus, 57.1% for excoriation, 78.6% for erythema and 78.6% for alopecia. The efficacy rate of the 5000 units/kg group was high for all signs evaluated and comparable to that of the 10 000 units/kg group reported in a previous study. The results of this study showed that 2000 units/kg of rCaIFN-gamma is less effective than 5000 units/kg to treat dogs with AD, and the efficacy of the 5000 units/kg dose is comparable to that of 10 000 units/kg at week 8.

Abstract
OBJECTIVE To determine the association of distinct clinical subsets with myositis-specific autoantibodies (MSAs) towards anti-155/140-kDa polypeptides [anti-155/140 antibodies (Abs)], anti-140-kDa polypeptides (anti-140 Abs), and anti-aminoacyl tRNA synthetases (ARS Abs) in Japanese patients with dermatomyositis (DM). METHODS We compared the clinical features and short-term prognoses of 30 DM patients whose serological status included these MSAs. The MSAs were determined by immunoprecipitation. RESULTS Anti-155/140 Abs (n = 5), anti-140 Abs (n = 8), and anti-ARS Abs (n = 7) did not overlap each other. All of the anti-155/140 Ab-positive patients (n = 5) were complicated by malignancies, as were all of the anti-140 Ab-positive patients (n = 8), who showed rapidly progressive interstitial lung disease (ILD). The survival rate at 6 months from the diagnosis of DM was significantly lower in the anti-140 Ab-positive patients than in the other patients. CONCLUSION This is the first study to report, in a single cohort of DM patients, that distinct clinical subsets are distributed in an anti-155/140 Ab-positive group, an anti-140 Ab-positive group, or an anti-ARS Ab-positive group. Our data also confirm previous evidence that anti-155/140 Abs are involved in malignancies and that anti-140 Abs are involved in rapidly progressive ILD.

Abstract
Studies have demonstrated that B cells play important roles in systemic sclerosis (SSc), especially through the CD19/CD22 autoimmune loop. CD22 is a B cell-specific inhibitory receptor that dampens B cell antigen receptor (BCR) signalling via tyrosine phosphorylation-dependent mechanism. In this study, we examined the presence and functional property of circulating autoantibodies reacting with CD22 in systemic sclerosis. Serum samples from 10 tight skin (TSK/+) mice and 50 SSc patients were assessed for anti-CD22 autoantibodies by enzyme-linked immunosorbent assays using recombinant mouse or human CD22. The association between anti-CD22 antibodies and clinical features was also investigated in SSc patients. Furthermore, the influence of SSc serum including anti-CD22 autoantibodies for CD22 tyrosine phosphorylation was examined by Western blotting using phosphotyrosine-specific antibodies reacting with four major tyrosine motifs of CD22 cytoplasmic domain. Anti-CD22 autoantibodies were positive in 80% of TSK/+ mice and in 22% of SSc patients. Patients positive for anti-CD22 antibodies showed significantly higher modified Rodnan skin thickness score compared with patients negative for anti-CD22 antibodies. Furthermore, anti-CD22 antibodies from patients' sera were capable of reducing phosphorylation of all four CD22 tyrosine motifs, while sera negative for anti-CD22 antibodies did not affect CD22 phosphorylation. Thus, a subset of SSc patients possessed autoantibodies reacting with a major inhibitory B cell response regulator, CD22. Because these antibodies can interfere CD22-mediated suppression onto B cell activation in vitro, SSc B cells produce functional autoantibodies that can enhance their own activation. This unique regulation may contribute to the autoimmune aspect of SSc.

Abstract
Early diagnosis of systemic sclerosis (SSc) may allow the start of treatment that could slow disease progression. For this reason early diagnosis of the disease is of pivotal importance. However, the lack of diagnostic criteria and valid predictors significantly limit patient evaluation and the use of potentially effective drugs in the earliest phase of SSc. Early SSc may be suspected on the basis of Raynaud's phenomenon, puffy fingers, autoantibodies and SSc capillaroscopic pattern. In practice, the aim is to have criteria for the diagnosis of very early SSc. The criteria that are proposed are obviously provisional and need to be validated: (a) initially through a Delphi technique; (b) thereafter perhaps using already available datasets; but (c) of critical importance, through prospective studies. Only after prospective studies can these potential criteria be considered validated. The consensus on criteria for the classification of very early SSc might be part of the evolving EULAR/ACR project of reclassification of SSc.

Abstract
Despite the heterogeneity of SSc, almost all patients have skin involvement. As such, skin manifestations are critical in the initial diagnosis of SSc and in the subsequent sub-classification into the different subsets of disease. The two principal subsets are lcSSc and dcSSc. The main difference between these two subsets is the speed of disease progression and the extent and severity of skin and visceral involvement; lcSSc has an insidious onset with skin involvement confined largely to the face and extremities. Whilst vascular manifestations of SSc such as pulmonary arterial hypertension are typically more common in lcSSc, patients in both subsets can develop ischaemic digital ulcers. In dcSSc, disease progression is very rapid, with skin thickening extending beyond the extremities and earlier, more widespread internal organ involvement. DcSSc is generally considered to be the more severe subset of the disease. Skin scores in SSc correlate inversely with survival and are considered a valuable marker of disease severity. Skin involvement is easily detectable and, using the modified Rodnan skin score, the degree of skin fibrosis can be quantified. As well as general management measures, a number of targeted therapies are commonly used for treatment of cutaneous manifestations of SSc. These include the intravenous prostanoid iloprost and the dual endothelin receptor antagonist bosentan, which is approved in Europe for the prevention of new digital ulcers.

Abstract
e16556 Background: Ovarian cancer is one of the most lethal malignancies in women. Despite recent studies of many oncogenes and tumor-suppressor genes concerning about its progression, the details of ovarian cancer biology still remains to be unclear. P-glycoprotein (P-gp) encoded by the MDR1 gene is a membrane protein that can export many kinds of antineoplastic agents from cells, and overexpression of P-gp has been reported to be implicated in treatment failure in cancer. DNA methylation, a major epigenetic process, can affect every step in carcinogenesis as well as genetic alterations. The contribution of such epigenetic alteration to the expression of MDR1 remains largely unexplored in human ovarian cancer. Methods: In this study, we evaluated the DNA methylation status of the MDR1 gene by methylation-specific PCR. Then, the expression of MDR-1 mRNA and protein in primary epithelial ovarian cancer specimens were evaluated by real-time RT-PCR and immunohistochemistry using anti-mouse P-gp F4 monoclonal antibody, respectively. The correlation between these results and clinicopathological features was examined. Results: MDR1 was hypermethylated in 12 of 12 (100%) ovarian cancer cell lines, and 5 of 13 (38%) primary ovarian cancers by methylation-specific PCR analysis. MDR1 mRNA expression was subsequently found to be lost in ovarian cancer cell lines with methylation by both real-time RT-PCR and immunohistochemistry. Thus, MDR1expression was associated with the DNA methylation status of the MDR1 gene. Conclusions: In conclusion, MDR1 was frequently hypermethylated in human ovarian cancers. Our results suggest that epigenetic regulation might play a role in the expression of MDR1 and clinical treatment outcomes in human ovarian cancer. No significant financial relationships to disclose.

Abstract
e16532 Background: The breast cancer susceptibility gene 1 (BRCA1) is mutated in half of hereditary breast cancers, and in about 80% of hereditary breast and ovarian cancers. Also, BRCA1 expression is decreased in sporadic breast cancers by other mechanisms, such as epigenetic alteration, suggesting its important role in sporadic breast cancers. The epigenetic alteration of BRCA1 and its contribution in sporadic ovarian tumors are not fully understood. Methods: We evaluated the DNA methylation status of the BRCA1 5’ CpG island by methylation-specific PCR in 12 human ovarian cancer cell lines and 39 primary epithelial ovarian tumor specimens. Cases included the following: malignant (n = 16), borderline (n = 8), and benign (n = 16) tumors. The correlation between these results and clinicopathological features was examined. Results: BRCA1 was hypermethylated in one of 12 (8%) ovarian cancer cell lines and 15 of 39 (38%) primary ovarian tumors. Relative to clinicopathological features, BRCA1 methylation was detected in 39% of malignant and borderline tumors and in 38% of benign tumors, suggesting the importance of BRCA1 pathway in both types of tumors. Some adjacent nontumorous tissues also showed aberrant methylation. Conclusions: BRCA1 was found to be frequently hypermethylated both in benign and malignant ovarian tumors. Our results suggest that epigenetic alteration of BRCA1 might play a role in the development of benign and malignant sporadic ovarian tumors. No significant financial relationships to disclose.

Abstract
5585 Background: We conducted the present surveillance to clarify the significance of adjuvant radiotherapy and the cause of poor outcome of adenocarcinoma (AC). Methods: A total of 825 patients with FIGO stage Ib-IIb cervical cancer, who underwent type III radical hysterectomy in 10 institutes of SGSG/ TGCU Intergroup between April 1997 and March 2003, were enrolled in this study. There were 543 patients with squamous cell carcinoma (SCC) (261 in stage Ib1, 67 in Ib2, 83 in IIa, 132 in IIb) and 282 with AC (186 in stage Ib1, 39 in Ib2, 11 in IIa, 46 in IIb). Mean age of patients was 49.0 yrs (range: 19–84 yrs) in SCC and 46.6 yrs (range: 18–84) in AC. Two hundred and fifty-five patient with SCC and 69 with AC received adjuvant radiotherapy including CCRT. Results: The 5-year overall survival rate (OS) for patients with SCC and AC were 87.4% and 83.4%. The OS for stage I patients did not differ between SCC and AC. Stage II patients with AC showed significantly worse prognosis compared with SCC (54.5% vs. 87.4% in IIa, 63.3% vs. 78.8% in IIb). There was a significant difference in OS for patients receiving adjuvant treatment between SCC and AC (83.0% vs. 73.9%). Although the OS for stage I patients did not differ between SCC and AC, the OS for stage II patients with AC was significantly lower (86.9% vs. 50.0% in IIa, 75.5% vs. 61.1% in stage IIb). In patients with stage I, SCC showed significantly higher lymphnode involvement compared with AC (16.5% vs. 9.7% in Ib1, 46.3% vs. 20.1% in Ib2). The incidence of lymphnode involvement did not differ between SCC and AC in patients with stage II (36.4% vs.34.9% in IIa and 39.1% vs.45.5% in IIb). When patients had lymphnode involvement, the outcome of patients with AC showed significantly worse than those with SCC (46.4% vs. 72.3%). The local failure defined as recurrence in stump and pelvis was more frequent in patients with AC compared with SCC (24.6% vs.10.7%). Conclusions: Although the incidence of lymphnode involvement did not differ between AC and SCC, AC patients with lymphnode involvement showed significantly worse outcome. The present study indicates that lower sensitivity to radiotherapy might be an important cause for the poorer prognosis in AC. No significant financial relationships to disclose.

Abstract
PURPOSE The optimal treatment of systemic sclerosis (SSc) is a challenge because the pathogenesis of SSc is unclear and it is an uncommon and clinically heterogeneous disease affecting multiple organ systems. The aim of the European League Against Rheumatism (EULAR) Scleroderma Trials and Research group (EUSTAR) was to develop evidence-based, consensus-derived recommendations for the treatment of SSc. METHODS To obtain and maintain a high level of intrinsic quality and comparability of this approach, EULAR standard operating procedures were followed. The task force comprised 18 SSc experts from Europe, the USA and Japan, two SSc patients and three fellows for literature research. The preliminary set of research questions concerning SSc treatment was provided by 74 EUSTAR centres. RESULTS Based on discussion of the clinical research evidence from published literature, and combining this with current expert opinion and clinical experience, 14 recommendations for the treatment of SSc were formulated. The final set includes the following recommendations: three on SSc-related digital vasculopathy (Raynaud's phenomenon and ulcers); four on SSc-related pulmonary arterial hypertension; three on SSc-related gastrointestinal involvement; two on scleroderma renal crisis; one on SSc-related interstitial lung disease and one on skin involvement. Experts also formulated several questions for a future research agenda. CONCLUSIONS Evidence-based, consensus-derived recommendations are useful for rheumatologists to help guide treatment for patients with SSc. These recommendations may also help to define directions for future clinical research in SSc.

Abstract
OBJECTIVES To validate the association of a single nucleotide polymorphism (SNP) of the connective tissue growth factor gene (CTGF) with susceptibility to systemic sclerosis (SSc) in the Japanese population. METHODS 395 Japanese patients with SSc, 115 patients with rheumatoid arthritis and 269 healthy Japanese volunteers were enrolled in the study. An SNP (rs6918698) at -945 bp from the start codon in the promoter region of the CTGF gene was determined by allelic discrimination with the use of a specific TaqMan probe. RESULTS The G allele showed a significantly higher frequency in patients with SSc than in controls (p<0.001; odds ratio 1.5; 95% confidence interval 1.2 to 1.9). In particular, the clinical subsets of SSc showed a more significant association between the G allele and diffuse cutaneous SSc (p<0.001) and the presence of interstitial lung disease (p<0.001), the presence of anti-topoisomerase I antibody (p<0.001) and anti-U1RNP antibody (p = 0.010). Association analyses using the genotype of the SNP yielded results similar to those of analyses using the allele. CONCLUSIONS This study confirms the association between an SNP in the CTGF gene and susceptibility to SSc, especially in the presence of diffuse cutaneous SSc, interstitial lung disease and anti-topoisomerase I antibody. The results strongly suggest that this SNP may be a powerful indicator of severe skin and lung involvement in patients with SSc.

Abstract
Objective:To describe methods and procedures used for the development of the European League Against Rheumatism (EULAR)/EULAR Scleroderma Trial and Research group (EUSTAR) recommendations for the treatment of systemic sclerosis. In particular, the results of a web-based Delphi exercise aimed at selection of research questions and evidence from systematic literature research, as parts of the development of these recommendations, are presented in detail.Methods:In agreement with the EULAR standard operating procedures a Task Force was created that consisted of the EUSTAR board members, 10 systemic sclerosis (SSc) experts invited from outside the EUSTAR board and representing Europe, the USA and Japan, a clinical epidemiologist, 2 patients with SSc and 3 fellows for literature research. All EUSTAR centres were invited to contribute to the development of recommendations through submission and preliminary selection of the research questions. The systematic literature research was performed using the Pubmed, Medline, EMBASE and Cochrane databases. Retrieved trials were evaluated according to the Jadad classification, and the level of evidence was graded from 1 to 4. Outcome data for efficacy and adverse events were abstracted and effect size, number needed to treat (NNT) and number needed to harm (NNH) were calculated when appropriate.Results:In all, 65 EUSTAR Centres provided 304 research questions concerning SSc treatment. These questions were aggregated, subdivided into 19 treatment categories and then subjected to preliminary selection by a web-based Delphi technique. The final set of 26 research questions was created by the Expert Committee based on the results of the Delphi exercise and the expert’s experience.Conclusions:This paper is a comprehensive summary of the methods we used to build recommendations for the drug treatment of systemic sclerosis, combining an evidence based approach and expert opinion.

Abstract
OBJECTIVE To determine the clinical significance of heat shock protein (Hsp) 70, a sensitive biomarker for monitoring cellular stress, in systemic sclerosis (SSc), we investigated the prevalence and clinical correlation of serum Hsp70 levels in SSc patients. METHODS Serum Hsp70 levels were examined in 48 patients with SSc by enzyme-linked immunosorbent assay. RESULT Serum Hsp70 levels were significantly elevated in SSc patients compared to normal controls (n=30), and were similar between patients with diffuse cutaneous SSc (n=26) and those with limited cutaneous SSc (n=22). Serum Hsp70 levels were elevated in 27% of total SSc patients with 30% of diffuse cutaneous SSc patients and 23% of limited cutaneous SSc patients. Hsp70 levels were significantly increased in SSc patients with pulmonary fibrosis or contracture of phalanges compared with those without pulmonary fibrosis or contracture of phalanges. Serum Hsp70 levels correlated positively with modified Rodnan total skin thickness score, renal vascular resistance, serum levels of monocyte chemotactic protein-1, C-reacting protein, and serum levels of 8-isoprostane. CONCLUSION Serum Hsp70 levels were increased in SSc patients and were associated with pulmonary fibrosis, skin sclerosis, renal vascular damage, oxidative stress, and inflammation. These results suggest that Hsp70 is a useful serological marker for evaluating cellular stresses and the disease severity in SSc.

Abstract
Background Systemic sclerosis (SSc) is a connective tissue disorder with excessive fibrosis of the skin and various internal organs. Although SSc is a heterogeneous disease, it has been reported that the particular antinuclear antibodies (ANA) are often indicative of clinical features, disease course and overall severity. Objective To clarify the association of clinical and prognostic features with serum ANA in Japanese patients with SSc. Methods We studied 203 Japanese patients diagnosed with SSc, who visited our hospital during the period 1983–2005. Six SSc-related ANA were identified using indirect immunofluorescence, double immunodiffusion and immunoprecipitation assays. Results Patients with SSc were classified into six ANA-based subgroups and a group without ANA. As expected, antitopoisomerase I antibody (Ab, n = 64), anti-RNA polymerases (RNAP) Ab (n = 12) and anti-U3 RNP Ab (n = 5) were associated with diffuse cutaneous SSc, whereas anticentromere Ab (ACA, n = 75), anti-Th/To Ab (n = 7) and anti-U1 RNP Ab (n = 10) were frequently detected in patients with limited cutaneous SSc. Clinical features of the ANA-negative group (n = 10) were heterogeneous. Consistent with previous findings in Caucasian and/or black African patients, antitopoisomerase I Ab was associated with the involvement of vascular and pulmonary fibrosis, leading to decreased survival rate. However, no patients with anti-RNAP Ab developed renal crisis and the frequency of isolated pulmonary hypertension in patients with ACA, anti-Th/To Ab or anti-U3 RNP Ab was similar to that in other ANA-based subgroups. Conclusion These results indicate that the clinical relevance of SSc-related ANA in Japanese patients differs in some aspects from that in Caucasian and/or black African patients.

Abstract
OBJECTIVE To assess the association of CD40/CD40 ligand (CD40L) interactions with the development of skin fibrosis and autoimmunity in tight-skin (TSK/+) mouse, which is a mouse model for human systemic sclerosis. METHODS Newly born TSK/+ mice were treated with murine anti-CD40L monoclonal antibody (100 microg intraperitoneally weekly). Hypodermal thickness of 8-week-old female mice (defined as the thickness of a subcutaneous loose connective tissue layer beneath the panniculus carnosus) was measured under a light microscope. All skin sections were taken from the para-midline, upper back region. Serum anti-topoisomerase I autoantibody levels, serum immunoglobulin levels and plasma soluble CD40L levels were determined by enzyme-linked immunosorbent assay. For analysis of lymphocyte surface molecules, single cell suspensions of lymphocytes were stained by monoclonal antibodies. Proliferation of TSK/+ B cells and fibroblasts to anti-CD40 antibodies was assessed by the uptake of [3H]-labelled thymidine and bromodeoxyuridine, respectively. RESULTS The blockade of CD40/CD40L interactions by anti-CD40L monoclonal antibody significantly reduced cutaneous fibrosis (65%) and anti-topoisomerase I autoantibody in TSK/+ mice. Anti-CD40L monoclonal antibody also normalised B lymphocyte abnormal activation in TSK/+ mice, demonstrated by hyper-gamma-globulinaemia. Furthermore, augmented CD40/CD40L interactions in TSK/+ mice were suggested by upregulated expression of CD40L on CD4(+) T cells, elevated plasma soluble CD40L levels. The hyperresponsiveness to CD40 stimulation was also observed in TSK/+ B cells and fibroblasts. CONCLUSIONS Cutaneous fibrosis and autoimmunity in TSK/+ mice are closely correlated with CD40/CD40L interactions.

Abstract
BACKGROUND Human tissue kallikreins (KLKs) are a family of 15 trypsin-like or chymotrypsin-like secreted serine proteases (KLK1-KLK15). Multiple KLKs have been quantitatively identified in normal stratum corneum (SC) and sweat as candidate desquamation-related proteases. OBJECTIVES To quantify KLK5, KLK6, KLK7, KLK8, KLK10, KLK11, KLK13 and KLK14 in the SC and serum of patients with psoriasis, and their variation between lesional and nonlesional areas and with phenotype, therapy and severity. The overall SC serine protease activities were also measured. METHODS Enzyme-linked immunosorbent assays and enzymatic assays were used. RESULTS The lesional SC of psoriasis generally contained significantly higher levels of all KLKs. KLK6, KLK10 and KLK13 levels were significantly elevated even in the nonlesional SC. The overall trypsin-like, plasmin-like and furin-like activities were significantly elevated in the lesional SC. Plasmin-like activity was significantly elevated also in the nonlesional SC. The SC chymotrypsin-like activity was only slightly elevated in psoriasis. KLK7 serum levels did not differ between normal volunteers and patients with psoriasis. Serum KLK6, KLK8, KLK10 and KLK13 levels in patients with untreated psoriasis significantly correlated with Psoriasis Area and Severity Index score. Serum KLK5 and KLK11 levels decreased in patients with psoriasis after therapy, especially with etretinate. Patients with erythrodermic psoriasis exhibited significantly higher serum KLK levels than normal subjects or patients with psoriasis vulgaris or arthropathic psoriasis. CONCLUSIONS We found aberrant KLK levels in the SC and serum of patients with psoriasis and suggest that KLKs might be involved in the pathogenesis of this disease.

Abstract
Activating and inhibitory signal transducers, CD19 and CD22, have been substantially implicated both in human systemic sclerosis (SSc) and tight-skin mouse, a model for SSc. We previously showed that a single nucleotide polymorphism (SNP) in CD19 promoter region was significantly associated with increased CD19 expression level and with susceptibility to SSc. In the present study, we examined whether CD22 polymorphisms were associated with susceptibility to SSc. CD22 variations were genotyped in 126 Japanese patients with SSc [47 diffuse cutaneous SSc and 79 limited cutaneous SSc (lcSSc)] and 93 unrelated healthy controls. At the c.2304C > A SNP coding for a synonymous substitution in exon 13, A/A genotype was observed in six patients with SSc (4.8 %) but none in the controls (P=0.040). All six patients with A/A genotype belonged to the lcSSc subgroup (7.6%, P=0.008 vs controls). Surface expression level of CD22 tended to be lower in B cells from the patients with A/A genotype (n=5) as compared with C/A (n=7) or C/C (n=14) genotype (17% decrease, P=0.0032). Taken together with our previous observation on CD19 polymorphism, intrinsic difference in the expression level of CD19 and CD22 was suggested to play a causative role in a proportion of patients with lcSSc.

Abstract
16049 Background: Adenosquamous carcinoma (ASC) of the uterine cervix is a rare mixture of malignant squamous and glandular epithelial elements. Clinical analyses of this disease were hardly performed independently from those of adenocarcinoma (AC) of the uterine cervix since both of the patients with these diseases show poorer outcome, compared with those with squamous cell carcinoma, which is present in the majority of cervical cancer. In this study, we investigated clinical features including diagnosis and treatment of this disease. Methods: During 1980–2006, total of 270 patients, who were diagnosed as carcinoma of the uterine cervix, were included in our analysis. A retrospective review of patients with ASC were preformed in their age, stage, lymph node metastasis, tumor markers (SCC, CEA, CA125 and CA19–9), treatment, relapse rate and its location, and survival. Results: There were total of 17 and 34 patients, who were histologically confirmed as having ASC (6.3%) and AC (12.6%) of the uterine cervix, respectively. All the ASC patients underwent surgery. The average age of the patients was 45.0 (26–78). The distribution of illness stages among the patients were IA, 4; IB, 8; IIA, 2; IIB, 2; IIIB, 1. Lymph node metastasis was seen in two patients (11.8%). There were no significant difference in these indexes between ASC and AC. Elevation of serum CA125 was observed in two ASC patients but no AC patients. The recurrence rates were 17.6% and 14.7% in ASC and AC, respectively. Five-year survival were 77.8% in ASC and 78.0% in AC, whereas 92.2% in SCC. Conclusions: These analyses indicate that clinical behavior and its outcome of ASC is similar to those of AC. The treatment based on these clinical features may be a useful to improve the prognosis of this disease. No significant financial relationships to disclose.

Abstract
5590 Background: We conducted the present study to determine the significance of radiotherapy for cervical adenocarcinoma. Methods: A total of 1,133 patients with cervical cancer, who underwent radiotherapy in 7 institutes between 1996 and 2005, were enrolled in this study. There were 966 squamous cell carcinoma (SCC) and 167 adenocarcinoma (AC). The mean age of patients with AC was 53.6 (range: 28–81) and 55.9 (range: 22–92) for SCC. Patients were distributed as follows: 370 in stage 1b, 116 in stage IIa, 344 in stage IIb, 16 in stage IIIa, 240 in stage IIIb, and 47 in stage IVa. All patients were identified with the medical records. Of 1,133 patients, 544 received radiotherapy as primary treatment, and 589 underwent adjuvant radiotherapy. Results: Regarding primary treatment, the 5-year survival rate for AC was 41.8% and that for SCC was 62.5% (p=0.0172). The rate of refractory or recurrence for patients with AC was significantly higher than that for SCC (53.3% vs. 33.3%, p=0.0068). Patients with AC more commonly showed recurrence inside irradiated field compared with SCC (83.3% vs. 58.2%, p=0.0240). The outcome for patients with AC was significantly worse compared with SCC in adjuvant treatment (5-year survival rate: 27.5% vs. 45.4%, p=0.0434). Recurrence for AC were significantly higher observed than that for SCC (40.0% vs. 24.7%, p=0.0008). The incidence of recurrence inside irradiated field and lymph node involvement did not differ between AC and SCC (30.1% vs. 43.8%, 46.7% vs. 44.0%). Conclusions: Cervical adenocarcinoma had poorer prognosis because of its low radiosensitivity compared with SCC. New strategy for cervical adenocarcinoma should be necessary. No significant financial relationships to disclose.

Abstract
BACKGROUND Adhesion molecules such as intercellular adhesion molecule-1 (ICAM-1) are thought to contribute to the airway inflammation and airway hyper-responsiveness (AHR) of allergic asthma. Some differences from allergic asthma have been noted, including airway neutrophilia, and the involvement of ICAM-1 in toluene diisocyanate (TDI) asthma is currently unclear. OBJECTIVE We utilized mice lacking ICAM-1 expression (ICAM-1(-/-)) to investigate the role of ICAM-1 in airway inflammation and AHR in TDI-induced asthma. METHODS Male C57BL/6J mice (ICAM-1(+/+)) and ICAM-1(-/-) mice were intranasally sensitized to TDI solution or solvent alone. Airway inflammation, AHR and cytokine secretion were assessed 24 h after challenge by TDI or solvent. The production of antigen-specific IgG and IgE by TDI sensitized and non-sensitized mice was determined. RESULTS TDI challenge to ICAM-1(+/+) mice induced an increase in airway inflammatory cell numbers, AHR and cytokine secretion of TNF-alpha, macrophage inflammatory protein-2 (MIP-2), IL-4, IL-5 and IFN-gamma into the bronchoalveolar lavage fluid. All these pathophysiological changes were reduced in ICAM-1(-/-) mice. Serum levels of TDI-specific IgG and IgE of ICAM-1(-/-) and ICAM-1(+/+) mice were comparable. CONCLUSION These results suggest that ICAM-1 plays an essential role in airway inflammation and AHR in TDI-induced asthma.

Abstract
BACKGROUND The transforming growth factor-beta (TGF-beta) system plays a critical role both in systemic sclerosis (SSc) and hereditary hemorrhagic telangiectasia (HHT). Endoglin, known as a gene responsible for HHT, is a TGF-beta receptor preferentially expressed on endothelial cells. The role of endoglin in SSc is potentially intriguing since limited cutaneous SSc (lcSSc) and HHT share several symptoms, including telangiectasia. OBJECTIVE To determine serum levels of soluble endoglin (sEndoglin) and clinical associations in patients with SSc. METHODS Serum sEndoglin levels were examined by ELISA in 70 patients with SSc, 20 patients with systemic lupus erythematosus and 20 healthy individuals. RESULTS Serum sEndoglin levels were significantly elevated in patients with lcSSc compared with diffuse cutaneous SSc and systemic lupus erythematosus patients as well as normal controls. Patients with elevated sEndoglin levels had telangiectasia more frequently than those with normal sEndoglin levels. Furthermore, pulmonary artery pressure was positively correlated with sEndoglin levels in patients with lcSSc. CONCLUSION Abnormal expression/function of endoglin may be linked to lcSSc-specific manifestations.

Abstract
OBJECTIVE Myositis-specific autoantibodies (MSAs) are a useful tool in diagnosis, defining clinical subsets and predicting prognosis of dermatomyositis (DM) and polymyositis (PM). In this study, we identified a novel MSA reactive with 155 and 140 kDa nuclear proteins [anti-155/140 antibody (Ab)] and determined the clinical feature of DM patients positive for this autoantibody (autoAb). METHODS Sera from 52 Japanese patients with DM, 9 with PM, 48 with systemic lupus erythematosus (SLE), 126 with systemic sclerosis and 18 with idiopathic interstitial pneumonia were examined by immunoprecipitation assays. Positive sera were further characterized by immunodepletion and immunofluorescence staining. RESULTS Seven of the 52 (13%) Japanese patients with DM immunoprecipitated 155 and 140 kDa proteins from 35S-labelled K562 leukaemia cell extract. No patients with SLE, systemic sclerosis or idiopathic interstitial pneumonia as well as healthy controls were positive for this autoAb. Patients with anti-155/140 Ab developed heliotrope rash, Gottron's papules or sign and flagellate erythema significantly more frequently than those negative. Notably, internal malignancy was found at significantly higher frequency in those positive than those negative (71 vs 11%; P < 0.005). In contrast, none of these patients positive for this autoAb had interstitial lung disease. CONCLUSIONS This novel MSA is associated with cancer-associated DM and may serve as a diagnostic serological marker for this specific subset.

Abstract
Malignant melanoma is often accompanied by a host response of inflammatory cell infiltration that is highly regulated by multiple adhesion molecules. To assess the role of adhesion molecules, including L-selectin and intercellular adhesion molecule-1 (ICAM-1), in this process, subcutaneous primary growth and metastasis to the lung of B16 melanoma cells not expressing L-selectin, ICAM-1 or their ligands were examined in mice lacking L-selectin, ICAM-1 or both. Primary subcutaneous growth of B16 melanoma was augmented by loss of L-selectin, ICAM-1 or both, while pulmonary metastasis was enhanced by the loss of L-selectin or combined loss of L-selectin and ICAM-1. In both situations, the combined loss of L-selectin and ICAM-1 exhibited the greatest effect. This enhancement was associated generally with a reduced accumulation of natural killer (NK) cells, CD4+ T cells and CD8+ T cells and also with a diminished release of interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha but not interleukin (IL)-6. Cytotoxicity against melanoma was not defective by the absence of ICAM-1, L-selectin or both, suggesting that the enhancement of tumour growth and metastasis caused by the loss of adhesion molecules results from an impaired migration of effector cells into the tissue rather than from a suppression of the cytotoxic response. The results indicate that L-selectin and ICAM-1 contribute co-operatively to the anti-tumour reaction by regulating lymphocyte infiltration to the tumour.

Abstract
OBJECTIVE To determine serum levels and clinical correlation of 8-isoprostane, which is produced in vivo through free radical-catalysed peroxidation of arachidonic acid and reflects oxidative stress, in patients with systemic sclerosis (SSc). METHODS Serum 8-isoprostane levels from 32 patients with diffuse cutaneous SSc (dSSc) and 25 patients with limited cutaneous SSc (lSSc) were examined by enzyme-linked immunosorbent assay. RESULTS Serum 8-isoprostane levels were elevated in dSSc and lSSc patients by 75-fold compared with normal controls (n=32). Serum 8-isoprostane levels correlated negatively with pulmonary function, such as percentage vital capacity and diffusion capacity for carbon monoxide, and correlated positively with renal vascular damage determined by colour flow Doppler ultrasonography. Serum 8-isoprostane levels also correlated positively with serum levels of IgG and anti-agalactosyl IgG autoantibody. CONCLUSION Increased 8-isoprostane levels correlated with the severity of pulmonary fibrosis, the extent of renal vascular damage and immunological abnormalities in SSc, suggesting that enhanced oxidative stress is related to the development of SSc.

Abstract
OBJECTIVE To determine serum levels of monocyte chemotactic protein-3 (MCP-3) and its clinical associations in patients with systemic sclerosis (SSc). METHODS Serum MCP-3 levels from 69 patients with SSc were examined by ELISA. RESULTS Serum MCP-3 levels were raised in patients with SSc (n = 69) compared with healthy controls (n = 28). Patients with diffuse cutaneous SSc (n = 36) had higher levels of serum MCP-3 than those with limited cutaneous SSc (n = 33). Patients with raised MCP-3 levels had pulmonary fibrosis and decreased vital capacity (VC) more often than those with normal MCP-3 levels. MCP-3 levels correlated positively with the extent of skin fibrosis, and inversely with %VC and carbon monoxide transfer factor (Tlco) in patients with SSc. CONCLUSION MCP-3 levels were increased in patients with SSc, and correlated with the extent of skin sclerosis and the severity of pulmonary fibrosis. These results suggest that MCP-3 may have a role in the development of fibrosis in SSc.

Abstract
OBJECTIVE Although some antiphospholipid antibodies (Abs) are found in patients with localized scleroderma (LSc), Ab against phosphatidylserine-prothrombin complex (PS/PT) has not been examined. We investigated anti-PS/PT Ab levels in patients with LSc. METHODS IgG anti-PS/PT Ab levels in serum samples taken from patients with LSc (n = 42) were measured using ELISA. RESULTS IgG anti-PS/PT Ab was detected in 17% of the LSc patients, while it was not detected in any normal controls (n = 32) or psoriasis vulgaris (n = 25), and this frequency was similar to that of systemic sclerosis (17%, n = 41). Among 3 LSc subgroups, generalized morphea, the severest form of LSc, had a frequency (27%) comparable with that of systemic lupus erythematosus (32%, n = 25). Among 7 LSc patients with anti-PS/PT Ab, 2 developed symptomatic thromboembolism (A 70-year-old man developed deep vein thrombosis and pulmonary infarction, although he was negative for other antiphospholipid Abs. A 6-year-old boy positive for lupus anticoagulant had cerebral infarction). By contrast, symptomatic thromboembolism was not detected in 35 LSc patients without anti-PS/PT Ab. CONCLUSION Patients with LSc, especially generalized morphea, exhibit anti-PS/PT Ab at a frequency comparable with collagen diseases such as systemic sclerosis and systemic lupus erythematosis. Examination of this Ab may be useful to recognize the risk of thromboembolism in patients with LSc.

Abstract
Epithelial-mesenchymal transdifferentiation (EMT) is a critical morphogenic event that occurs during embryonic development and during the progression of various epithelial tumors. EMT can be induced by transforming growth factor (TGF)-beta in mouse NMuMG mammary epithelial cells. Here, we demonstrate a central role of helix-loop-helix factors, E2A and inhibitor of differentiation (Id) proteins, in TGF-beta-induced EMT. Epithelial cells ectopically expressing E2A adopt a fibroblastic phenotype and acquire migratory/invasive properties, concomitant with the suppression of E-cadherin expression. Id proteins interacted with E2A proteins and antagonized E2A-dependent suppression of the E-cadherin promoter. Levels of Id proteins were dramatically decreased by TGF-beta. Moreover, NMuMG cells overexpressed Id2 showed partial resistance to TGF-beta-induced EMT. Id proteins thus inhibit the action of E2A proteins on the expression of E-cadherin, but after TGF-beta stimulation, E2A proteins are present in molar excess of the Id proteins, thus over-riding their inhibitory function and leading to EMT.

Abstract
BACKGROUND Human tissue kallikreins are a gene family (KLK1-KLK15) encoding for 15 secretory serine proteases (hK1-hK15). Two tissue kallikrein proteins, hK5 and hK7, were previously found in the stratum corneum (SC), stratum granulosum (SG) and appendages. hK8 was also shown to be secreted via lamellar granules and numerous KLK mRNAs were previously identified. KLKs are believed to be responsible for desquamation of corneocytes and sebum, sweat and hair maturation. OBJECTIVES To demonstrate immunohistochemically the expression of hK6, hK8 and hK13 in normal skin tissue and to show an increased cell number expressing kallikrein mRNAs and proteins in psoriasis vulgaris (PV) and atopic dermatitis (AD). METHODS Samples of normal, PV and AD skin were obtained. hK6-, hK8- and hK13-specific antibodies were produced and used for immunohistochemical analysis. Multiple KLK mRNAs were synthesized and used for in situ hybridization study. RESULTS Three other hKs, namely hK6, hK8 and hK13, were immunohistochemically identified as new skin serine proteases in the whole SC, SG, sebaceous glands, eccrine sweat glands, hair follicles and nerves. We also demonstrated an increased number of cells expressing KLK mRNAs and hKs in PV and AD. In PV, KLK mRNAs/hKs were predominantly expressed in the upper epidermis. In AD, hK distribution was rather diffuse and expanded into the lower epidermis. CONCLUSIONS The colocalization of various hKs seems to be essential for the regulation of serine protease activity in skin and for steady desquamation and skin barrier function. Moreover, the increased number of cells expressing multiple KLK mRNA and hK in PV and AD could be a clue to elucidate their pathogenesis.

Abstract
OBJECTIVE We sought to assess serum cutaneous T-cell-attracting chemokine (CTACK) levels and CTACK expression levels in skin from patients with systemic sclerosis (SSc), and determine whether serum CTACK levels correlate with clinical features in SSc patients. METHODS Serum samples were obtained from 73 SSc patients, 32 patients with systemic lupus erythematosus and 26 patients with dermatomyositis. Serum CTACK levels were determined by enzyme-linked immunoabsorbent assay. CTACK mRNA expression in sclerotic skin was assessed by real-time reverse transcription-polymerase chain reaction. RESULTS Serum CTACK levels were significantly increased in patients with diffuse cutaneous SSc (dSSc; n=32) and those with limited cutaneous SSc (lSSc; n=41) compared with normal controls (n=31; P<0.05 and P<0.0005, respectively). The presence of calcinosis and muscle involvement was more frequently detected in SSc patients with elevated CTACK levels (P<0.05 and P<0.05, respectively). Elevated C-reactive protein levels were also observed more frequently in SSc patients with increased CTACK levels (P<0.05). CTACK mRNA expression levels in the sclerotic skin of SSc patients were augmented. In a longitudinal study, serum CTACK levels were generally decreased during the follow-up. CONCLUSIONS The increased serum CTACK levels and enhanced skin CTACK expression in SSc patients suggest that CTACK is related to the inflammation associated with SSc.

Abstract
Heat-shock proteins are highly conserved and immunogenic proteins, which may be involved in the initiation and perpetuation of autoimmune diseases. Heat-shock protein 47 (HSP47) is expressed by collagen-secreting cells such as fibroblasts and serves as a collagen-specific molecular chaperone that plays a crucial role in collagen metabolism. Abnormal collagen accumulation and autoimmunity are characteristics of systemic sclerosis (SSc). We determined the presence and prevalence of autoantibodies to HSP47 in patients with SSc and also in tight-skin (TSK/+) mice, an animal model for SSc. Anti-HSP47 autoantibodies were present in SSc patients with a frequency of 26%, while patients with systemic lupus erythematosus, those with dermatomyositis, those with keloid and healthy subjects did not have anti-HSP47 antibodies. IgG1 and IgG2 were the major Ig isotypes of the autoantibodies. Patients positive for anti-HSP47 had a significantly shorter duration of disease than those who were negative. Anti-HSP47 autoantibodies were also positive in 79% of TSK/+ mice. Thus, autoantibodies to HSP47 were present in the sera from SSc patients as well as those from TSK mice, and may be associated with the pathogenesis of SSc.

Abstract
Psoriasis is believed to be a T cell-mediated autoimmune disease, but also exhibits autoantibody production. Calpastatin is an endogenous inhibitor of calpain, a ubiquitous protease that regulates inflammatory processes. Anti-calpastatin autoantibody was first identified as an autoantibody specific to rheumatoid arthritis, but has been also detected in other autoimmune diseases. In this study, we examined the presence and levels of anti-calpastatin antibody in 77 psoriasis patients by enzyme-linked immunosorbent assay. Compared with normal controls, psoriasis patients exhibited significantly elevated IgG anti-calpastatin antibody levels that were similar to those found in rheumatoid arthritis patients. Remarkably, IgG anti-calpastatin autoantibody in sera from psoriasis patients inhibited calpastatin activity. Calpain II expression was up-regulated in psoriasis skin lesions compared with normal skin while calpastatin expression was normal. The results of this study reveal the presence of anti-calpastatin autoantibody in psoriasis.

Abstract
BACKGROUND Fractalkine expressed on endothelial cells mediates activation and adhesion of leucocytes expressing its receptor, CX(3)CR1. Soluble fractalkine exhibits chemotactic activity for leucocytes expressing CX(3)CR1. OBJECTIVE To determine the role of fractalkine and its receptor in systemic sclerosis (SSc) by assessing their expression levels in patients with this disease. METHODS The expression of fractalkine and CX(3)CR1 in the skin and lung tissues was immunohistochemically examined. Circulating soluble fractalkine levels were examined by enzyme linked immunosorbent assay (ELISA). Blood samples from patients with SSc were stained for CX(3)CR1 with flow cytometric analysis. RESULTS CX(3)CR1 levels on peripheral monocytes/macrophages and T cells were found to be raised in patients with diffuse cutaneous SSc. The numbers of cells expressing CX(3)CR1, including monocytes/macrophages, were increased in the lesional skin and lung tissues from patients with diffuse cutaneous SSc. Fractalkine was strongly expressed on endothelial cells in the affected skin and lung tissues. Soluble fractalkine levels were significantly raised in sera and were associated with raised erythrocyte sedimentation rates, digital ischaemia, and severity of pulmonary fibrosis. CONCLUSIONS Up regulated expression of fractalkine and CX(3)CR1 cooperatively augments the recruitment of mononuclear cells expressing CX(3)CR1 into the affected tissue of SSc, leading to inflammation and vascular injury.

Abstract
OBJECTIVES There have been many studies suggesting that localized scleroderma has a strong autoimmune background, although the lesions are usually limited to the skin and subcutaneous tissue. Here we summarize previous data on the autoimmunity of localized scleroderma, mostly published in the last two decades, because there has not been a review paper summarizing autoimmunity in this disorder. METHODS We classified the previous reports into three categories: antinuclear antibodies; cytokine and soluble receptors; and cell adhesion molecules and cell surface molecules. In each category, we introduce the important investigations. RESULTS High frequencies of antinuclear antibodies, detected by the indirect immunofluorescence method using cultured cells, are confirmed by many groups. The major autoantigens have been revealed to be histones. Recently, anti-topoisomerase II alpha antibody has been found to be detected highly frequently in localized scleroderma, while anti-topoisomerase I antibody, which is highly specific for systemic sclerosis, has not been detected in any case of localized scleroderma. In other studies, elevated serum cytokines and cell adhesion molecules suggest the immunoactivation of localized scleroderma. CONCLUSIONS Many previous studies conclude that localized scleroderma involves autoimmune abnormalities and is one of the organ-specific autoimmune disorders targeting mainly skin, although the types of autoimmune abnormality are different from systemic sclerosis.

Abstract
Systemic sclerosis (SSc) is characterized by multi-organ fibrosis with an autoimmune background. Although autoantibodies are detected frequently in SSc patients, the role of autoantibody in the development of fibrosis remains unknown. Connective tissue homeostasis is a balance between the synthesis and degradation of the extracellular matrix (ECM); ECM degradation is regulated mainly by matrix metalloproteinases (MMPs). Anti-MMP-1 antibody is suggested to inhibit MMP-1 and be involved in the development of the fibrosis in SSc. However, the accumulation of various ECM components in the tissue of SSc cannot be explained by the anti-MMP-1 antibody alone. In this study, we examined the presence or levels of antibody to MMP-3, a protein which degrades various ECM components relevant to SSc fibrosis. Enzyme-linked immunosorbent assay (ELISA) using human recombinant MMP-3 revealed that IgG anti-MMP-3 autoantibody levels were elevated significantly in the sera from SSc patients, but not in patients with active systemic lupus erythematosus or dermatomyositis. IgG and IgM anti-MMP-3 antibody levels were significantly higher in diffuse cutaneous SSc, a severe form, than those in limited cutaneous SSc. Consistently, IgG anti-MMP-3 antibody levels correlated significantly with fibrosis of the skin, lung and renal blood vessels. The presence of IgG anti-MMP-3 autoantibody in sera from SSc patients was confirmed by immunoblotting analysis. Remarkably, MMP-3 activity was inhibited by IgG anti-MMP-3 antibody. These results suggest that anti-MMP-3 antibody is a serological marker that reflects the severity of SSc and also suggest that it may contribute to the development of fibrosis by inhibiting MMP-3 activity and reducing the ECM turnover.

Abstract
OBJECTIVE To determine the frequency and clinical association of antiphosphatidylserine-prothrombin complex (PS/PT) antibody (Ab) in systemic sclerosis (SSc). METHODS Anti-PS/PT IgG Ab was examined by enzyme linked immunosorbent assay (ELISA) in 112 patients with SSc. Thirty three healthy volunteers and 30 patients with systemic lupus erythematosus (SLE) were also investigated as controls. RESULTS Anti-PS/PT Ab was detected in 18/112 (16%) patients with SSc and 10/30 (33%) patients with SLE, whereas it was not detected in any normal controls. Anti-PS/PT Ab was more frequently detected in patients with SSc with peripheral ischaemia and lung disease (pulmonary fibrosis and pulmonary hypertension) than in patients with SSc without the Ab. However, anti-PS/PT Ab was not associated with the severity of skin sclerosis. Importantly, two patients were negative for both lupus anticoagulant and Ab against cardiolipin beta(2)-glycoprotein I complex among six anti-PS/PT Ab positive patients with SSc and a thromboembolic episode. CONCLUSIONS Anti-PS/PT Ab is associated with thromboembolism, peripheral ischaemia, and lung involvement in some patients with SSc. Examination of this Ab may be useful to recognise the risk of thromboembolism in patients with SSc.
