Abstract
A 75-year-old woman visited our hospital with constipation. Colonoscopy revealed a submucosal tumor in the rectum. She was followed up as a case of mucosal prolapse syndrome. Six years later, she was referred to our hospital due to hematochezia and abdominal pain. Colonoscopy revealed that the submucosal tumor had an ulcerative appearance with bleeding. Low anterior resection was performed. Amyloid protein deposition was detected from the submucosa to subserosa. Other organs showed no evidence of amyloidosis; we therefore diagnosed the patient with localized rectal amyloidosis. This is a rare case of symptomatic localized rectal amyloidosis whose long-term progression was able to be endoscopically observed.

Abstract
Bacteria of the family Flavobacteriaceae (flavobacteria) primarily comprise nonpathogenic bacteria that inhabit soil and water (both marine and freshwater). However, some bacterial species in the family, including Flavobacterium psychrophilum and Flavobacterium columnare, are known to be pathogenic to fish. Flavobacteria, including the abovementioned pathogenic bacteria, belong to the phylum Bacteroidota and possess two phylum-specific features, gliding motility and a protein secretion system, which are energized by a common motor complex. Herein, we focused on Flavobacterium collinsii (GiFuPREF103) isolated from a diseased fish (Plecoglossus altivelis). Genomic analysis of F. collinsii GiFuPREF103 revealed the presence of a type IX secretion system and additional genes associated with gliding motility and spreading. Using transposon mutagenesis, we isolated two mutants with altered colony morphology and colony spreading ability; these mutants had transposon insertions in pep25 and lbp26. The glycosylation material profiles revealed that these mutants lacked the high-molecular-weight glycosylated materials present in the wild-type strain. In addition, the wild-type strains exhibited fast cell population movement at the edge of the spreading colony, whereas reduced cell population behavior was observed in the pep25- and lbp26-mutant strains. In the aqueous environment, the surface layers of these mutant strains were more hydrophobic, and they formed biofilms with enhanced microcolony growth compared to those with the wild-type. In Flavobacterium johnsoniae, the Fjoh_0352 and Fjoh_0353 mutant strains were generated, which were based on the ortholog genes of pep25 and lbp26. In these F. johnsoniae mutants, as in F. collinsii GiFuPREF103, colonies with diminished spreading capacity were formed. Furthermore, cell population migration was observed at the edge of the colony in wild-type F. johnsoniae, whereas individual cells, and not cell populations, migrated in these mutant strains. The findings of the present study indicate that pep25 and lbp26 contribute to the colony spreading of F. collinsii.

Abstract
We report on two patients with stasis symptoms, including vomiting and nausea that were caused by deformity, stenosis, and decreased gastric peristalsis associated with artificial ulcers after endoscopic submucosal dissection (ESD). In both cases, the symptoms remained unresolved despite repetitive endoscopic balloon dilation (EBD). Therefore, laparoscopic gastrojejunostomy was performed. Soon after the procedure, their food intake was improved. Laparoscopic gastrojejunostomy can be an option for the treatment of gastric outlet obstruction induced by a large field of gastric ESD that is refractory to EBD.

Abstract
Background In patients with average risk of bleeding, second-look endoscopy does not reportedly reduce bleeding after gastric endoscopic submucosal dissection. However, effectiveness of second-look endoscopy for patients with a high risk of bleeding, such as those who are taking antithrombotic agents, is unclear. Hence, this study aims to clarify the effectiveness of second-look endoscopy for patients with antithrombotic therapy. Methods We studied 142 consecutive patients with 173 gastric epithelial neoplasms who were routinely taking antithrombotic agents and were treated by endoscopic submucosal dissection at Tonan Hospital between November 2013 and December 2019. They were classified into two groups: those with second-look endoscopy (SLE group, 69 patients with 85 lesions) and those without second-look endoscopy (non-SLE group, 73 patients with 88 lesions). The incidence of post-endoscopic submucosal dissection bleeding was compared between the SLE and non-SLE groups. Results There were no statistical differences in the rate of patients undergoing single antiplatelet therapy, single anticoagulant therapy, and multiple therapy between the SLE and non-SLE groups (SLE group vs. non-SLE group; 32 [46.4%], 16 [23.2%], and 21 [30.4%] patients vs. 37 [50.7%], 20 [27.4%], and 16 [21.9%] patients, respectively; p = 0.50). Post-endoscopic submucosal dissection bleeding incidence was 21.7% (15/69) and 21.9% (16/73) in the SLE and non-SLE groups, respectively, and did not significantly differ between the two groups (p = 0.98). Conclusions For patients taking antithrombotic agents, the incidence of post-endoscopic submucosal dissection bleeding was not reduced by second-look endoscopy.

Abstract
Background Recent studies have shown that mixed predominantly differentiated-type (MD) early gastric cancer (EGC) might have more malignant potential than pure differentiated-type (PD) EGC. However, no study has analyzed all differentiated-type EGC cases treated endoscopically and surgically. This study aimed to compare the differences in clinicopathological features and long-term prognosis between MD- and PD-EGC. Methods We evaluated all patients with differentiated-type EGCs who were treated endoscopically and surgically in our hospital between January 2010 and October 2014. The clinicopathological features and long-term prognosis of MD-EGC were compared with those of PD-EGC. Results A total of 459 patients with 459 lesions were evaluated in this study; of them, 409 (89.1%) and 50 (10.9%) were classified into the PD and MD groups, respectively. Submucosal invasion was found in 96 (23.5%) patients of the PD group and in 33 (66.0%) patients of the MD group (p < 0.01). The rates of positive lymphatic and vascular invasion and ulceration were significantly higher in the MD group than in the PD group (p < 0.01). The proportion of patients with lymph node metastasis was also significantly higher in the MD group than in the PD group (5 (10%) vs 6 (1.5%), p < 0.01). The 5-year overall and EGC-specific survival rates in the PD group were 88.3 and 99.5%, respectively, while they were 94.0 and 98.0% in the MD group, respectively. Conclusions MD-EGC has more malignant potential than PD-EGC. However, the long-term prognosis of MD-EGC is good and is not significantly different from that of PD-EGC when treated appropriately.

Abstract
Background Endoscopic removal of colorectal adenoma is considered an effective treatment for reducing the mortality rates associated with colorectal cancer. Warfarin, a type of anticoagulant, is widely used for the treatment and prevention of thromboembolism; however, bleeding may increase with its administration after polypectomy. In recent times, a high incidence of bleeding after endoscopic polypectomy has been reported in patients receiving heparin bridge therapy. However, previous studies have not compared the bleeding rate after endoscopic colorectal polypectomy between patients who continued with anticoagulant therapy and those who received heparin bridge therapy. We hypothesised that endoscopic colorectal polypectomy under the novel treatment with continuous warfarin is not inferior to endoscopic colorectal polypectomy under standard treatment with heparin bridge therapy with respect to the rate of postoperative bleeding. This study aims to compare the efficacy of endoscopic colorectal polypectomy with continuous warfarin administration and endoscopic colorectal polypectomy with heparin bridge therapy with respect to the rate of postoperative bleeding. Methods We will conduct a prospective multicentre randomised controlled non-inferiority trial of two parallel groups. We will compare patients scheduled to undergo colorectal polypectomy under anticoagulant therapy with warfarin. There will be 2 groups, namely, a standard treatment group (heparin bridge therapy) and the experimental treatment group (continued anticoagulant therapy). The primary outcome measure is the rate of postoperative bleeding. On the contrary, the secondary outcomes include the rate of cumulative bleeding, rate of overt haemorrhage (that does not qualify for the definition of haemorrhage after endoscopic polypectomy), incidence of haemorrhage requiring haemostasis during endoscopic polypectomy, intraoperative bleeding during endoscopic colorectal polypectomy requiring angiography, abdominal surgery and/or blood transfusion, total rate of bleeding, risk factors for postoperative bleeding, length of hospital stay, incidence of thromboembolism, prothrombin time-international ratio (PT-INR) 28 days after the surgery, and incidence of serious adverse events. Discussion The results of this randomised controlled trial will provide valuable information for the standardisation of management of anticoagulants in patients scheduled to undergo colorectal polypectomy.

Abstract
To investigate the effects of preventing temperature decrease on the reproductive activity of the male cold-water teleost, Cottus pollux SE, testicular development, serum 11-ketotestosterone (11-KT) levels, and physiological responses associated with nesting behavior (i.e., elevation of serum 11-KT levels and accumulation of urine in the urinary bladder) were observed from November to January. Specifically, males were exposed to three different cooling regimes (control, 16 to 6 °C; H1, 16 to 11 °C; H2, 16 to 14 °C), and the results were compared. In addition, the effects of temperature on male reproductive behavior were also clarified. At higher water temperature regimes, the rate of testicular development and serum 11-KT levels were both higher from November to mid-December than from mid-December to January. However, the results showed that high water temperature regimes in the coldest period of winter did not suppress spermatogenesis completely. Conversely, the physiological responses to nesting were affected by high water temperatures, with serum 11-KT levels increasing and urine accumulation in the urinary bladder being suppressed. Furthermore, frequencies of two behaviors associated with nesting, i.e., body undulation and face displays, were also suppressed under high water temperatures (~ 14 °C) compared with normal temperatures (~ 7 °C) during the breeding season. Based on the physiological and behavioral responses to nesting, findings showed that preventing a water temperature decrease during winter suppresses reproductive activity in Cottus pollux SE.

Abstract
OBJECTIVE Although there have been established guidelines for first surveillance colonoscopy (FSC) after a polypectomy, there is no consensus on performing a second surveillance colonoscopy (SSC), especially in Asian countries. This study aimed to investigate the association of SSC findings with index total colonoscopy (TCS) and FSC results. METHODS This was a single-center retrospective cohort study involving 1928 consecutive Japanese patients who had received three or more colonoscopies. High-risk colonoscopic findings were defined as advanced adenoma (≥10 mm in size, with a villous histology or high-grade dysplasia) or more than three adenomas, whereas low-risk findings were defined as one to two non-advanced adenomas. On the basis of index TCS results, the patients were divided into three groups: no adenomas (NA) (n = 888), low-risk (LR) (n = 476), and high-risk (HR) (n = 564) groups, respectively. RESULTS In the NA group, the rate of high-risk findings on SSC was significantly higher in patients with high-risk or low-risk findings on FSC than in those with no adenoma (7.7% and 7.9% vs 2.2%, P < 0.05). Patients in the LR and HR groups with high-risk findings on FSC had a significantly higher risk on SSC than those with low-risk findings or no adenoma on FSC (LR group: 28.6%, 9.4%, and 5.9%, respectively, P < 0.01; HR group: 34.5%, 18.8%, and 7.9%, respectively, P < 0.01). CONCLUSIONS Index TCS and especially FSC findings were predictive of SSC results. The study results may be useful for determining appropriate intervals for surveillance colonoscopy in Asian countries.

Abstract
The brightness of aurorae in Earth’s polar region often beats with periods ranging from sub-second to a few tens of a second. Past observations showed that the beat of the aurora is composed of a superposition of two independent periodicities that co-exist hierarchically. However, the origin of such multiple time-scale beats in aurora remains poorly understood due to a lack of measurements with sufficiently high temporal resolution. By coordinating experiments using ultrafast auroral imagers deployed in the Arctic with the newly-launched magnetospheric satellite Arase, we succeeded in identifying an excellent agreement between the beats in aurorae and intensity modulations of natural electromagnetic waves in space called “chorus”. In particular, sub-second scintillations of aurorae are precisely controlled by fine-scale chirping rhythms in chorus. The observation of this striking correlation demonstrates that resonant interaction between energetic electrons and chorus waves in magnetospheres orchestrates the complex behavior of aurora on Earth and other magnetized planets.

Abstract
Background/Aims The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees.
Methods This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups.
Results The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group.
Conclusions Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.

Abstract
BACKGROUND AND AIMS Endoscopic submucosal dissection (ESD) is widely used as a minimally invasive treatment for large esophageal cancers, but prolonged procedure duration and life-threatening adverse events remain matters of concern. We aimed to determine whether traction-assisted ESD (TA-ESD) is superior to conventional ESD in terms of technical outcomes. METHODS A superiority, randomized, phase III trial was conducted at 7 institutions across Japan. Patients with large esophageal cancer (defined as tumor diameter >20 mm) were eligible for this study. Enrolled patients were randomly assigned to undergo conventional ESD or TA-ESD. The primary endpoint was ESD procedure duration. RESULTS Two hundred forty-one patients were recruited and randomized. On applying exclusion criteria, 117 and 116 patients who underwent conventional ESD and TA-ESD, respectively, were included in the baseline analysis. In 1 patient, conventional ESD was discontinued because of severe perforation. Thus, the final analysis included 116 patients per group (primary analysis). The ESD procedure duration was significantly shorter for TA-ESD than for conventional ESD (44.5 minutes vs 60.5 minutes, respectively; P < .001). Moreover, no adverse events were noted in the TA-ESD group. The rate of horizontal margin involvement did not differ between the groups (10.3% vs 6.9% for conventional ESD and TA-ESD, respectively; P = .484). CONCLUSIONS TA-ESD was superior to conventional ESD in terms of procedure duration and was not associated with any adverse events. TA-ESD should be considered the procedure of choice for large esophageal cancers. (Clinical trial registration number: UMIN000024080.).

Abstract
Purpose We previously created a self-assembled cartilage-like complex in vitro from only three cartilage components, hyaluronic acid (HA), aggrecan (AG) and type II collagen, without other materials such as cross-linking agents. Based on this self-organized AG/HA/collagen complex, we have created three novel types of biphasic cartilage and bone-like scaffolds combined with hydroxyapatite (HAP) for osteochondral tissue engineering. These scaffolds have been developed from self-assembled cartilage component molecules and HAP at the nanometer scale by manipulating the intermolecular relations. Patients and methods The surface structure of each self-organized biphasic cartilage and bone-like scaffold was evaluated by scanning electron microscopy, whereas the viscoelasticity was also analyzed in vitro. Three types of artificial cartilage–HAP conjugates were implanted into an osteochondral defect in rat knee joints, and bone and cartilage tissues of the implanted site were examined 4 and 8 weeks after implantation. The tissues were examined histopathologically to evaluate the effects of the implantation on the articular cartilage and subchondral bone tissues. Results Our in vitro and in vivo data reveal that the self-organized biphasic cartilage and bone-like scaffold conjugated with HAP are superior to the scaffold with no HAP in both cartilage regeneration and subchondral bone regeneration. Conclusion Our present study indicates that the self-organized biphasic cartilage and bone-like scaffold, which is conjugated with an HAP layer, may have potential not only to repair articular cartilage defects but also to ameliorate the degeneration of subchondral bone in the diseases with osteochondral defect.

Abstract
This study was performed to elucidate the molecular function of the synoviocyte proliferation-associated in collagen-induced arthritis (CIA) 1/serum amyloid A-like 1 (SPACIA1/SAAL1) in mice CIA, an animal model of rheumatoid arthritis (RA), and human RA-synovial fibroblasts (RASFs). SPACIA1/SAAL1-deficient mice were generated and used to create mouse models of CIA in mild or severe disease conditions. Cell cycle-related genes, whose expression levels were affected by SPACIA1/SAAL1 small interfering RNA (siRNA), were screened. Transcriptional and post-transcriptional effects of SPACIA1/SAAL1 siRNA on cyclin-dependent kinase (cdk) 6 gene expression were investigated in human RASFs. SPACIA1/SAAL1-deficient mice showed later onset and slower progression of CIA than wild-type mice in severe disease conditions, but not in mild conditions. Expression levels of cdk6, but not cdk4, which are D-type cyclin partners, were downregulated by SPACIA1/SAAL1 siRNA at the post-transcriptional level. The exacerbation of CIA depends on SPACIA1/SAAL1 expression, although CIA also progresses slowly in the absence of SPACIA1/SAAL1. The CDK6, expression of which is up-regulated by the SPACIA1/SAAL1 expression, might be a critical factor in the exacerbation of CIA.

Abstract
A 66-year-old man underwent follow-up colonoscopy after colon polypectomy. The retroflexed view of the anal canal with white-light imaging revealed a whitish, slightly elevated lesion on the dentate line and an ill-defined flat lesion. A biopsy of the whitish elevation revealed squamous cell carcinoma (SCC), and endoscopic submucosal dissection (ESD) was planned. The lateral margin of the SCC was identified by spraying with Lugol's iodine, and the tumor was resected en bloc with no complications. The pathological findings were SCC in situ with parakeratosis in the whitish elevation and high-grade intraepithelial neoplasia in the ill-defined flat lesion, which exhibited a wide iodine-unstained area by chromoendoscopy. Early SCC in the anal canal is a rare gastrointestinal cancer, and Lugol chromoendoscopy helped visualize the tumor margin for ESD.

Abstract
Abstract
It has been reported that the Natural killer (NK) cell with FCGR3A (CD16a) V genotype is associated with enhanced clinical response to IgG1 monoclonal Ab (mAb) therapy such as trastuzumab, rituximab and cetuximab (1,2), suggesting a role of antibody-dependent cell-mediated cytotoxicity (ADCC) induced by NK cells. NK cells express three types of polymorphism of CD16; FcγRIIIa-158 VV, VF, FF, which are derived from the genotype of FCGR3A. It is a clinical challenge to improve the outcome in patients with FCGR3A 158FF genotype whose NK cells have lower affinity to mAb and mediate poor ADCC activity. The IL-15 superagonist/IL-15Rα-Fc fusion complex (ALT-803) activates the IL-15 receptor on CD8 T cells and NK cells, inducing their expansion, cytotoxity, and ADCC against B cell lymphoma (3, 4, 5).
Here, we examined the effect of ALT803 on NK cell-mediated ADCC activity by the the anti-HER2 IgG1 mAb trastuzumab in HER2+ cell lines (SKBR3, BT474, MDA-MB-453). In addition, we used the anti-epidermal growth factor receptor(EGFR) IgG1 mAb cetuximab in EGFR positive TNBC cell lines (MDA-MB-231, SUM149, BT549). Finally, we examined the anti-PD-L1 IgG1 mAb avelumab was used for PD-L1 positive breast cancer cell lines (MDA-MB-231, BT549). Trastuzumab, cetuximab, and avelumab all significantly increased NK cell-induced lysis via ADCC. ALT803 significantly further increased both NK induced lysis and ADCC activity in all the cell lines. There was a significant positive correlation for the mean of ADCC lysis induced by NK cells from three FF (21%), three VF (33%), three VV (45%) donors. ALT803 significantly increased the mean of ADCC lysis by NK cells from all donors of each genotype to the same extent. ALT803 increased the expression of NK cell-activating receptors and cytotoxic granules regardless of the genotype of NK cell FCGR3A in terms VV, VF, or FF.
We further examined the potential of ALT803 for NK cell-cytotoxicity suppressed by TGF-β1 which is one of the main barriers to immunity in the tumor microenvionment (TME). NK cells treated with TGF-β1 showed lower expression of activating receptors and cytotoxic granules, culminating in decreased lysis of MDA-MB231. ALT803 inhibited TGF-β1 from down-regulating the expression of NK cell-activating receptors and cytotoxic granules, and from suppressing the cytotoxicity of NK cells to MDA-MB231.
In conclusion, the IL-15 superagonist ALT803 can potentially increase the clinical benefit of ADCC-based mAb therapy for breast cancer patients, regardless of the genotype of FCGR3A. Moreover, ALT803 prevented NK cell-cytotoxity from TGF-β1-induced suppression, providing a rationale for ALT803 therapy to overcome TME-mediated immunosuppression.

Abstract
BACKGROUND Only a few studies have reported long-term outcomes for endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) in elderly patients. The aim of this study was to evaluate the efficacy of ESD for EGC in elderly patients ≥75 years with respect to both short- and long-term outcomes. METHODS We reviewed the clinical data of elderly patients ≥75 years who had undergone ESD for EGC at Tonan Hospital from January 2003 to May 2010. RESULTS A total of 177 consecutive patients, including 145 with curative resection (CR) and 32 with noncurative resection (non-CR), were examined. Of the 32 patients with non-CR, 15 underwent additional surgery, and lymph node metastases were found in 3 patients. The remaining 17 patients were followed without additional surgery because of advanced age or poor general condition. Procedure-related complications, such as post-ESD bleeding, perforation and pneumonia, were within the acceptable range. The 5-year survival rates of patients with CR, those with additional surgery after non-CR, and those without additional surgery after non-CR were 84.6, 73.3, and 58.8 %, respectively. No deaths were attributable to the original gastric cancer; patients succumbed to other illnesses, including malignancy and respiratory disease. CONCLUSIONS In elderly patients, ESD is an acceptable treatment for EGC in terms of both short- and long-term outcomes. Careful clinical assessment of elderly patients is necessary before ESD. After ESD, medical follow-up is important so that other malignancies and diseases that affect the elderly are not overlooked.

Abstract
A 74-year-old woman with advanced gastric cancer was admitted to our hospital. A central venous (CV) port catheter was implanted into the right subclavian vein for preoperative chemotherapy and parenteral nutritional management. On the 35th day after implantation, she complained of diarrhea, fever and dyspnea. The chest radiograph showed a right-sided massive pleural effusion. As the patient progressively fell into severe respiratory distress, endotracheal intubation was performed for management of respiration by mechanical ventilation. Initially, given the patient's symptoms, she was diagnosed with septic shock. Therefore, after placement of a CV catheter through the right femoral vein, in consideration of the possibility of a port infection, she was treated with thoracentesis and infusion of antibiotics. The patient gradually recovered, and again received parenteral nutrition through the CV port catheter. After the infusion was administered, she complained of dyspnea. A CT scan of the chest revealed a right pleural effusion and displacement of the tip of the CV port catheter out of the wall of the superior vena cava. We diagnosed delayed vascular injury (DVI), and the CV port catheter was removed. She soon recovered with conservative treatment. We speculated that the initial respiratory symptoms such as the pleural effusion were caused by DVI. DVI should therefore be recognized as a complication related to implanted CV port catheters.

Abstract
Abstract
Aromatase inhibitors (AI) are the common treatment for postmenopausal estrogen receptor (ER) positive breast cancer. However, not a few of these patients acquire resistance to AI.To investigate this molecular mechanism of resistance, we have established several breast cancer cell lines as AI resistant models. Recently, we reported on AD-EDR cells (androgen metabolite-dependent and estrogen depletion resistant cells) derived from MCF-7, in which ER activity depends on one of androgen metabolite, 5a-androstane-3β, 17β-diol (3βdiol).
It is supposed that tumor heterogeneity contributes to the acquired resistance to drugs.To examine this diversity, we established another AI resistant model derived from T-47D, to compare characters of these AI resistant models from different parents. Then, we found that the androgen receptor (AR) signal acquired oncogenic role in this model in contrast to AD-EDR cells established from MCF-7.
We cultured ER positive breast cancer cells, T47D-TE8, stably transfected with ERE-GFP reporter into T47D, under estrogen-depleted and androgen-supplemented conditions for more than three months, simulating the AI treatment, and established estrogen deprivation-resistant cells (TE8-EDR cells).
TE8-EDR cells had little ERE-GFP activity and proliferation response to estrogen though estrogen stimulated proliferation of parental T47D-TE8. The mRNA for ER and progesterone receptor was hardly detected in TE8-EDR cells. These results suggested that they had lost the ER-mediated pathway of growth. On the contrary, Dihydrotestosterone (DHT) increased growth of T47D-TE8 cells, while it was more remarkable in TE8-EDR, and this proliferative effect was reduced by AR antagonist, bicalutamide. The mRNA expressions of AR and its target gene, PSA, were extremely increased in TE8-EDR cells. These results indicated that TE8-EDR enhanced AR-regulated pathway for growth.
Increased AR expression was presumed to be one of the factors elevating AR activity. To identify other elements enhancing AR-mediated signal, we compared the gene expression of TE8-EDR cells with that of T47D-TE8 by microarray analysis. The outcome showed that the expression of some well-known androgen-related genes were increased in TE8-EDR cells. Among these genes, we focused on DDC (L-dopa decarboxylase) which has been reported as one of the AR coactivator, and its overexpression increase proliferative effect in prostate cancer cell lines.By real-time RT-PCR, we confirmed that the mRNA expression of DDC in TE8-EDR was higher over one-hundred fold than T47D-TE8. In addition, DHT-induced proliferation was cancelled by DDC inhibitor, NSD-1015.
This study suggests that TE8-EDR cells shift their growth pathway from ER to AR signal, and the AR activity is enhanced by high-expression of DDC. Whereas, MCF7-derived AD-EDR cells still depends on ER signal for their proliferation. So far, few studies have shown the proliferative effects of androgen as AI resistant mechanism. Our results provide new mechanism of acquired AI-resistance in breast cancer. Moreover, the fact that the character of AI resistant models varied with their parent cells supports the hypothesis that tumor heterogeneity contributes to diversify the mechanism of acquired resistance to hormonal therapy.

Abstract
The incidence of rheumatic fever (RF) has markedly increased in the last 10 years in Kyrgyzstan. Therefore, investigating the prevalence of group A β-hemolytic streptococcus (GABHS), which is the cause of RF, in the Kyrgyzstan population is crucial. We studied 189 subjects: 59 children [29 with RF and/or rheumatic heart disease (RHD)] and 130 adults (15 with RHD). The average age of the subjects was 41.0±10.0 years (range 8 months to 72 years). A general clinical examination and medical history including eating habits was carried out. The prevalence of GABHS was tested using the highly sensitive rapid antigen detection test (RADT) to detect the outcrop of streptococcus antigen in smears taken from the mucosal surface of the tonsils or the back of the throat. GABHS antigen was positive in 70 of a total 189 subjects [37.0%; 22/59 children (37.2%), 48/130 adults (36.9%)]. In patients with RF/RHD (n=44), GABHS was positive in 14 subjects [31.8%; 8/29 children (27.6%), 6/15 adults (40.0%)]. Thirty-two subjects with RF/RHD had frequent episodes of tonsillopharyngitis. In subjects without RF/RHD (n=145), GABHS was positive in 56 subjects [38.6%; 14/30 children (46.6%), 42/115 adults (36.5%)]. Thirty of these subjects had frequent episodes of tonsillopharyngitis. Of the 130 adults, the most-consumed dairy products included yoghurt (n=115; 88.4%), milk kasha (n=75; 57.7%) and milk (n=40; 30.7%). Of the 115 subjects in the yoghurt-consuming group, 44 (38.2%) had positive results for GABHS. In the non-yoghurt-consuming group, 4/15 subjects (26.6%) had positive results for GABHS. Using RADT for GABHS, a high prevalence of GABHS antigen was detected not only in patients with RF/RHD, but also in the healthy population (without RF/RHD). The low GABHS prevalence in children with RF/RHD (27.6%) was probably due to corresponding antibiotic therapy. In conclusion, the high prevalence of GABHS is one of the main reasons for the rapid increase in RF/RHD in Kyrgyzstan, and RADT would be an effective tool for its detection.

Abstract
Fucoxanthin-chlorophyll-a/c protein (FCP) complexes from brown algae Cladosiphon okamuranus TOKIDA (Okinawa Mozuku in Japanese) contain the only species of carbonyl carotenoid, fucoxanthin, which exhibits spectral characteristics attributed to an intramolecular charge-transfer (ICT) property that arises in polar environments due to the presence of the carbonyl group in its polyene backbone. Here, we investigated the role of the ICT property of fucoxanthin in ultrafast energy transfer to chlorophyll-a/c in brown algal photosynthesis using femtosecond pump-probe spectroscopic measurements. The observed excited-state dynamics show that the ICT character of fucoxanthin in FCP extends its absorption band to longer wavelengths and enhances its electronic interaction with chlorophyll-a molecules, leading to efficient energy transfer from fucoxanthin to chlorophyll-a.

Abstract
OBJECTIVE To identify novel genes associated with dysregulated proliferation of activated synovial fibroblasts, which are involved in arthritic joint destruction. METHODS We performed transcriptome analysis to identify genes that were up-regulated in the foot joints of mice with collagen-induced arthritis (CIA). The effect of candidate genes on proliferation of synovial fibroblasts was screened using antisense oligodeoxynucleotides and small interfering RNAs (siRNAs). We characterized the expression and function of a novel gene, synoviocyte proliferation-associated in collagen-induced arthritis 1 (SPACIA1)/serum amyloid A-like 1 (SAAL1) using antibodies and siRNA and established transgenic mice to examine the effect of SPACIA1/SAAL1 overexpression in CIA. RESULTS Human and mouse SPACIA1/SAAL1 encoded 474 amino acid proteins that shared 80% homology. SPACIA1/SAAL1 was primarily expressed in the nucleus of rheumatoid arthritis (RA) synovial fibroblasts and was highly expressed in the hyperplastic lining of inflamed synovium. In addition, its expression level in RA- or osteoarthritis (OA)-affected synovial tissue was positively correlated with the thickness of the synovial lining. Furthermore, SPACIA1/SAAL1 siRNA inhibited the proliferation of synovial fibroblasts, especially tumor necrosis factor α-induced synovial fibroblasts, by blocking entry into the S phase without inducing apoptosis. Finally, transgenic mice overexpressing SPACIA1/SAAL1 exhibited early onset and rapid progression of CIA. CONCLUSION These results suggest that SPACIA1/SAAL1 is necessary for abnormal proliferation of synovial fibroblasts and its overexpression is associated with the progression of synovitis in mice and humans. Thus, therapy targeting SPACIA1/SAAL1 might have potential as an inhibitor of synovial proliferation in RA and/or OA.

Abstract
BACKGROUND Human T-lymphotropic virus type-1 (HTLV-1) is a human retrovirus that causes HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and adult T-cell leukaemia (ATL). A higher viral load in individuals with HTLV-1 infection increases their risk of developing HAM/TSP and ATL. Moreover, the high proviral load is associated with the clinical progression of HAM/TSP. Reduction of the number of HTLV-1-infected cells is therefore crucial for preventing and treating HTLV-1-associated diseases. Recently, fucoidan, a complex sulphated polysaccharide derived from marine seaweed, has been demonstrated to exert inhibitory effects on HTLV-1 infection in vitro. In this study, we examined the in vivo effects of fucoidan on HTLV-1 infection. METHODS In this single-centre open-label trial, 13 patients with HAM/TSP were treated with 6 g fucoidan daily for 6-13 months. The HTLV-1 proviral DNA load and frequencies of HTLV-1-specific CD8(+) T-cells, natural killer cells, invariant natural killer T-cells and dendritic cells in the peripheral blood were analysed. Furthermore, the in vitro inhibitory effect of fucoidan on cell-to-cell HTLV-1 infection was examined by using luciferase reporter cell assays. RESULTS Fucoidan inhibited the cell-to-cell transmission of HTLV-1 in vitro. Furthermore, fucoidan therapy resulted in a 42.4% decrease in the HTLV-1 proviral load without affecting the host immune cells. During the treatment, no exacerbation was observed. Four patients with HAM/TSP developed diarrhoea, which improved immediately after stopping fucoidan administration. CONCLUSIONS Fucoidan is a new potential therapeutic agent for the prevention and treatment of HTLV-1-associated diseases.

Abstract
In 2005, the Medical Treatment and Supervision (MTS) Act was enacted in Japan to hospitalize the criminally insane and to promote a self-supporting lifestyle after deinstitutionalization. As of October 2010, 490 patients remain hospitalized in 23 highly secure forensic hospitals. Most patients are diagnosed with chronic schizophrenia and exhibit symptoms of drug resistance. Battering is the most common criminal act they have committed.The increased prevalence of the combination of criminal insanity with drug dependence is a common problem in other countries as well. It is a serious problem that diversity in prison medical care has not been achieved.A characteristic feature of care for criminally insane patients in Japan is that they must live in a residential district where a public health center is located and close to forensic hospitals after deinstitutionalization. Although there may be concerns about social prejudice against psychiatric disorders, this limited area would help support rehabilitation of patients because medical staff can easily know the whereabouts, psychiatric condition and aspects, of daily life for each patient through frequent reports obtained from home-visiting nurses. As a result, patients who have been successfully deinstitutionalized lead a self-supporting lifestyle without treatment interruption or repetition of similar criminal acts.In this presentation, we will show the current status of forensic care in Japan, analyze its characteristics and problems described above, and make suggestions for the treatment of the criminally insane in countries with a small national land area such as Japan.

Abstract
OBJECTIVES Matrix metalloproteinase (MMP) 13 is a pathogenic collagenase that causes cartilage destruction and plays a leading role in causing osteoarthritis. This study focused on 114 genes that are differentially expressed between intact and damaged osteoarthritis cartilage, in order to determine which molecules are involved in suppressing MMP-13 expression. METHODS MMP-13 concentrations were measured in the supernatant of human osteoarthritis chondrocyte cultures transfected with small interfering RNA (siRNA) against the 114 genes. MMP-13 levels changed most dramatically in response to siRNA against prostaglandin EP2 receptor. The authors performed further measurements of MMP-13 production in osteoarthritis chondrocytes stimulated by the EP2 agonist butaprost in the presence or absence of interleukin-1β (IL-1β) and/or cyclooxygenase-2 (COX-2) inhibitor. They also assessed the effect of butaprost on chondrocyte viability, and investigated the involvement of the cAMP-protein kinase A (PKA) pathway on EP2 signalling using inhibitors. Cartilage-related gene expression was examined in chondrocytes treated with butaprost. The authors also investigated which E series of prostaglandin (EP) receptors are expressed in osteoarthritis cartilage. RESULTS MMP-13 messenger RNA expression was significantly affected by two molecules, EP2 receptor and SLC14A1, a urea transporter. In IL-1β-treated osteoarthritis chondrocytes, butaprost suppressed MMP-13 production, which was further decreased by COX-2 inhibitor. EP2 signalling downregulated MMP-13 mRNA expression via the cAMP-PKA pathway without affecting cell viability. Although EP2 signalling enhanced IL-6 expression, the expressions of several catabolic factors (MMP-1, MMP-3, MMP-13, ADAMTS5, IL-1β and tumour necrosis factor alpha) were inhibited. EP2 receptor was the major EP receptor in osteoarthritis cartilage. CONCLUSION The results suggest that EP2 signalling has 'anti-catabolic' effects in osteoarthritis chondrocytes.

Abstract
BACKGROUND AND AIM Chronic hepatic damage leads to liver fibrosis, which is characterized by the accumulation of collagen-rich extracellular matrix. However, the mechanism by which E3 ubiquitin ligase is involved in collagen synthesis in liver fibrosis is incompletely understood. This study aimed to explore the involvement of the E3 ubiquitin ligase synoviolin (Syno) in liver fibrosis. METHODS The expression and localization of synoviolin in the liver were analyzed in CCl(4)-induced hepatic injury models and human cirrhosis tissues. The degree of liver fibrosis and the number of activated hepatic stellate cells (HSCs) was compared between wild type (wt) and Syno(+/-) mice in the chronic hepatic injury model. We compared the ratio of apoptosis in activated HSCs between wt and Syno(+/-) mice. We also analyzed the effect of synoviolin on collagen synthesis in the cell line from HSCs (LX-2) using siRNA-synoviolin and a mutant synoviolin in which E3 ligase activity was abolished. Furthermore, we compared collagen synthesis between wt and Syno(-/-) mice embryonic fibroblasts (MEF) using quantitative RT-PCR, western blotting, and collagen assay; then, we immunohistochemically analyzed the localization of collagen in Syno(-/-) MEF cells. RESULTS In the hepatic injury model as well as in cirrhosis, synoviolin was upregulated in the activated HSCs, while Syno(+/-) mice developed significantly less liver fibrosis than in wt mice. The number of activated HSCs was decreased in Syno(+/-) mice, and some of these cells showed apoptosis. Furthermore, collagen expression in LX-2 cells was upregulated by synoviolin overexpression, while synoviolin knockdown led to reduced collagen expression. Moreover, in Syno(-/-) MEF cells, the amounts of intracellular and secreted mature collagen were significantly decreased, and procollagen was abnormally accumulated in the endoplasmic reticulum. CONCLUSION Our findings demonstrate the importance of the E3 ubiquitin ligase synoviolin in liver fibrosis.

Abstract
INTRODUCTION Microorganisms are able to survive and induce persistent infection in periapical tissues. The aim of this study was to investigate the composition of the microflora of persistent apical periodontitis lesions. METHODS Twenty apical lesion samples were obtained from 20 patients with chronic apical periodontitis by root end surgery and processed using aerobic or anaerobic culture techniques. All isolated strains were identified by 16S ribosomal DNA sequence analysis. RESULTS Seventy-four strains were isolated, belonging to 31 bacterial species obtained from the 20 apical lesions that were isolated. The majority of the strains were facultative anaerobes (51.6%). Propionibacterium acnes, Staphylococcus epidermidis, Pseudomonas aeruginosa and Fusobacterium nucleatum were isolated from 16.2, 9.5, 6.8 and 5.4% of the samples, respectively. Fifteen samples harboured more than one species. The predominant association was P. acnes, S. epidermidis and F. nucleatum. CONCLUSION The microbiota of persistent apical periodontitis lesions is composed by diverse types of microorganisms with biofilm-forming capacity, including P. acnes, S. epidermidis and F. nucleatum.

Abstract
Isaac's syndrome is a movement disorder characterized by hyperexcitability of peripheral motor nerves. Patients with Isaac's syndrome often develop auto-antibodies to voltage-gated potassium channels (VGKCs) which block their function. However, anti-VGKC antibodies are not detected in all patients with Isaac's syndrome, suggesting the existence of another etiology. In this study, we performed immunoscreening using the serum from a patient with Isaac's syndrome and identified the novel gene named Kenae/CCDC125. Expression analysis of Kenae/CCDC125 revealed that its transcript was highly expressed in tissues associated with the immune system, such as the thymus, spleen and bone marrow. In cells stably expressing Kenae/CCDC125, delay in cell motility and deregulation of RhoGTPase (RhoA, Rac1 and cdc42) activity to extracellular stimuli were demonstrated. These results suggest that the novel gene, Kenae/CCDC125, acts as a regulator of cell motility through RhoA, Rac1 and cdc42.

Abstract
Background Human T-lymphotropic virus type 1 (HTLV-1) is a human retrovirus associated with both HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), which is a chronic neuroinflammatory disease, and adult T-cell leukemia (ATL). The pathogenesis of HAM/TSP is known to be as follows: HTLV-1-infected T cells trigger a hyperimmune response leading to neuroinflammation. However, the HTLV-1-infected T cell subset that plays a major role in the accelerated immune response has not yet been identified. Principal Findings Here, we demonstrate that CD4+CD25+CCR4+ T cells are the predominant viral reservoir, and their levels are increased in HAM/TSP patients. While CCR4 is known to be selectively expressed on T helper type 2 (Th2), Th17, and regulatory T (Treg) cells in healthy individuals, we demonstrate that IFN-γ production is extraordinarily increased and IL-4, IL-10, IL-17, and Foxp3 expression is decreased in the CD4+CD25+CCR4+ T cells of HAM/TSP patients as compared to those in healthy individuals, and the alteration in function is specific to this cell subtype. Notably, the frequency of IFN-γ-producing CD4+CD25+CCR4+Foxp3− T cells is dramatically increased in HAM/TSP patients, and this was found to be correlated with disease activity and severity. Conclusions We have defined a unique T cell subset—IFN-γ+CCR4+CD4+CD25+ T cells—that is abnormally increased and functionally altered in this retrovirus-associated inflammatory disorder of the central nervous system.
