Abstract
OBJECTIVES To investigate who needs a careful postoperative monitoring for prostate cancer (PCa) after holmium laser enucleation of the prostate (HoLEP). We examined characteristics and oncological outcomes of HoLEP-related PCa. METHODS Patients who underwent HoLEP during 2002-2017 in a Japanese tertiary center were retrospectively analyzed. Patients were divided into non-PCa, PCa with HoLEP specimen (PCa-Ope), and PCa diagnosed during follow-up (PCa-Post). Outcomes of all HoLEP-related PCa were monitored. RESULTS Of the total 758, 60 (7.9%) were diagnosed with PCa from resected specimen of HoLEP and 9 (1.2%) were diagnosed postoperatively. Preoperative prostate-specific antigen (iPSA), postoperative PSA (pPSA), and PSA density were significantly higher in both PCa groups than those in non-PCa group. While iPSA significantly correlated to prostate volume (PV), pPSA was not associated with PV. A receiver-operating-characteristics curve demonstrated that pPSA 1.2 ng/mL achieved the optimal cut-off (AUC 0.95) for the incidence of PCa-Post. In addition to the incidence of PCa and iPSA, lower enucleation efficiency (enucleated volume /PV) was significantly associated with pPSA >1.2 ng/mL. Among PCa-Ope, 51 were Grade Group (GG) ≤2 and 42 were followed-up with active surveillance, whereas 8 of 9 PCa-Post were GG ≥3 and 2 progressed to death. CONCLUSIONS Patients undergoing HoLEP are associated with some risk of potential PCa. While oncological outcomes were favorable among PCa-Ope, postoperative PSA should be carefully monitored even if not diagnosed with PCa with HoLEP specimen. Enucleation efficiency should be also considered not to misread pPSA value.

Abstract
Poor prognostic cardiac function is known among some patients with primary aldosteronism (PA). However, studies with echocardiograms on whether the normalization of aldosterone after laparoscopic adrenalectomy (LADX) improves myocardial hypertrophy and diastolic cardiac dysfunction have been inadequate. Between August 2009 and December 2021, 147 patients with unilateral PA who underwent pre- and post-LADX echocardiography at a single center were enrolled in this retrospective study. We evaluated the cardiac impact of LADX by comparing patients who demonstrated complete clinical success (CS) with those who demonstrated partial or absent CS. Adjusted odds ratios (ORs) for not obtaining complete CS were calculated using binomial logistic regression analysis for clinically significant items among the pre- and postoperative clinical and echocardiographic markers. Overall, 47 (29%) and 104 (71%) patients had complete and partial or absent CS, respectively. Compared to patients with complete CS, patients with partial CS or without CS tended to have preoperative low early to late diastolic transmitral flow velocity (E/A) (< 0.8 cm/s) (41% vs. 21%, P < 0.05) and postoperative supranormal left ventricular ejection fraction (LVEF) (> 70%) (37% vs. 21%, P < 0.05). Furthermore, laparoscopic adrenalectomy improved the low and high echocardiographic values of E/A and LVEF, respectively, in both groups. The risk factors for not reaching complete CS were male sex (OR 3.42), low preoperative E/A (OR 3.11), and postoperative supranormal LVEF (OR 3.17). Although low preoperative E/A and postoperative supranormal LVEF are associated with poor clinical outcomes, LADX can improve diastolic cardiac function in patients with PA.

Abstract
Although the response to combination therapy has been reported in patients with brain metastases from advanced renal cancer, treatment-related cerebral hemorrhage has not been adequately studied. The CheckMate 9ER clinical trial of nivolumab and cabozantinib excluded patients with brain metastases. Therefore, the associated treatment outcomes in these patients with brain metastases are unclear. Herein, we report a case of bleeding from brain metastases in a patient with advanced renal cancer after gamma knife combination therapy with nivolumab and cabozantinib. Fortunately, the cerebral hemorrhage of the patient was alleviated by conservative treatment. Despite treatment interruption, the metastatic lesions reduced in size, and treatment was gradually resumed. In this case study, we report the risk of cerebral hemorrhage in combination therapy for brain metastasis cases, how to manage hemorrhage cases, and their prognosis.

Abstract
In a rare case, free from systemic therapy, deferred cytoreductive nephrectomy was implemented in treating an advanced renal cell carcinoma with liver, lung, and splenic colon metastases. A 59-year-old man diagnosed with advanced renal cell carcinoma underwent deferred cytoreductive nephrectomy due to a partial response to systemic treatment after a period of 1 year. After the surgery, no additional treatment was implemented. Furthermore, after 10 months, the patient had no recurrence of renal cell carcinoma. Through a review of this case and deferred cases in the current literature, we could emphasize the importance of image evaluation and pathological findings as an indication for surgery and subsequent treatment options. However, there is room for debate with regards to the indications for deferred cytoreductive nephrectomy as well as a therapeutic strategy after the surgery. This report discusses the significance of deferred cytoreductive nephrectomy in terms of prognosis and quality-of-life improvement in advanced renal cancer.

Abstract
An 18-year-old Japanese man was diagnosed with an undifferentiated sarcoma of the spermatic cord, with multiple distant metastases to the lungs and bones. The patient received doxorubicin-based standard chemotherapy. Although the chemotherapy was effective, it induced severe adverse events, which led to treatment discontinuation. A comprehensive genomic profiling test using resected tumor tissue revealed the BRAF V600E mutation. Based on the result, the patient received combination therapy with dabrafenib and trametinib. The combination therapy achieved a good response with few adverse events. However, 6.5 months later, pleural metastases and meningeal dissemination had emerged. A liquid comprehensive genomic profiling test was performed after the progression to identify the resistance mechanism, which resulted in the detection of no actionable gene alterations other than BRAF V600E. This report shows that the BRAF V600E mutation may be a promising therapeutic target and that resistance to the targeted therapy could also occur in soft tissue sarcoma. The significance of BRAF mutations across different types of cancer should be validated, and it is necessary to apply targeted therapies and develop methods to overcome resistance based on the optimal use of comprehensive genomic profiling tests.

Abstract
Here, we discuss the safety and management of adverse events associated with pembrolizumab plus axitinib combination therapy for metastatic renal cell carcinoma in patients on hemodialysis. A 76-year-old man was diagnosed with cT3aN0M0 renal cell carcinoma due to gross hematuria. Stereoscopic radiotherapy for metastatic lesions of the ipsilateral kidney was performed 9 years after right laparoscopic radical nephrectomy. Soon after, the patient started to receive hemodialysis due to end-stage renal disease. Further stereoscopic radiotherapy was needed for metastasis of the ipsilateral kidney and lung. Fifteen years after diagnosis, systemic therapy was necessary to control new metastases, such as in the right scapular bone. We selected pembrolizumab plus axitinib combination therapy as the first-line systemic therapy for any risk as defined by the International Metastatic RCC Database Consortium. Although we needed to pay attention to the adverse events unique to hemodialysis, he underwent this combination therapy without any difficulty for 6 months. Here, we report the practice of combination therapy in patients on hemodialysis in light of the literature.

Abstract
PURPOSE Although cell-free DNA (cfDNA) testing is expected to drive cancer precision medicine, little is known about the significance of detecting low-frequency variants in circulating cell-free tumor DNA (ctDNA) in castration-resistant prostate cancer (CRPC). We aimed to identify genomic profile including low-frequency variants in ctDNA from patients with CRPC and investigate the clinical utility of detecting variants with variant allele frequency (VAF) below 1%. EXPERIMENTAL DESIGN This prospective, multicenter cohort study enrolled patients with CRPC eligible for treatment with abiraterone or enzalutamide. We performed targeted sequencing of pretreatment cfDNA and paired leukocyte DNA with molecular barcodes, and ctDNA variants with a VAF ≥0.1% were detected using an in-house pipeline. We investigated progression-free survival (PFS) and overall survival (OS) after different ctDNA fraction cutoffs were applied. RESULTS One hundred patients were analyzed (median follow-up 10.7 months). We detected deleterious ATM, BRCA2, and TP53 variants even in samples with ctDNA fraction below 2%. When the ctDNA fraction cutoff value of 0.4% was applied, significant differences in PFS and OS were found between patients with and without defects in ATM or BRCA2 [HR, 2.52; 95% confidence interval (CI), 1.24-5.11; P = 0.0091] and TP53 (HR, 3.74; 95% CI, 1.60-8.71; P = 0.0014). However, these differences were no longer observed when the ctDNA fraction cutoff value of 2% was applied, and approximately 50% of the samples were classified as ctDNA unquantifiable. CONCLUSIONS Detecting low-frequency ctDNA variants with a VAF <1% is important to identify clinically informative genomic alterations in CRPC.

Abstract
Colistin is one of the antibiotics of last resort for human health. However, the dissemination of the plasmid-mediated colistin resistance gene mcr-1 is of great concern globally. In the One Health framework, the environment is an important component for managing antimicrobial resistance. However, little information is available concerning the prevalence of mcr-1 in water environments. We aimed to reveal the prevalence of mcr-1 in different water environments in Hanoi, Vietnam. Quantitative PCR was applied to detect mcr-1 in four urban drainages receiving untreated domestic wastewater, three rivers, five lakes and two groundwater samples. Urban drainages contained higher concentrations of mcr-1, suggesting that urban residents carry the gene. The class 1 integron-integrase gene was identified as a good surrogate of antibiotic resistance genes including mcr-1. A significant correlation was found between the levels of mcr-1 and the human-specific cross-assembly phage, which is an indicator of human faecal pollution. These results indicated that the primary source of mcr-1 in urban water environments is human faeces, which is consistent with the fact that most domestic wastewater is untreated in Hanoi. The control of untreated wastewater is critical for alleviating the spread of mcr-1 in water environments in Vietnam.

Abstract
OBJECTIVE To evaluate the impact of cancer therapy on post-treatment ejaculation in patients with testicular cancer. METHODS A total of 74 testicular cancer survivors provided completed International Index of Erectile Function-15 questionnaires before and after treatment between 2010 and 2017. Sexual function, particularly ejaculatory function, was evaluated before and after treatment. In this study, patients who answered "1 = almost never/never" or "2 = a few times" for questionnaire number 9 (ejaculation frequency) were defined as having "ejaculation disorder." RESULTS Of 74 testicular cancer survivors, 50 (68%) had no ejaculation disorders before treatment. Four (44%) of nine survivors, who received chemotherapy and retroperitoneal lymph node dissection, developed ejaculation disorders after treatment. On multivariate analysis, retroperitoneal lymph node dissection was a significant predictor of post-treatment ejaculation disorder (P = 0.042). Of 60 survivors with evaluable ejaculation function after treatment, 24 (40%) did not attempt sexual intercourse, and multivariate analysis showed ejaculation disorder had a significant negative impact on having sexual intercourse (P = 0.035). Furthermore, the mean International Index of Erectile Function-15 scores in the groups with and without ejaculation disorders after treatment were 24.0 and 51.9, respectively (P < 0.001). CONCLUSION Ejaculation disorders occur at high rate after retroperitoneal lymph node dissection. Many testicular cancer survivors reporting no sexual intercourse have ejaculation disorders, suggesting an adverse impact on sexual life. Urologists should provide proper counselling regarding the risk of ejaculation disorder and its possible impact on sexual life.

Abstract
AIMS A continuous quench-flow (CQF) reactor was developed to collect samples at the reaction times of less than one second. The reactor is applied to determine ozone disinfection kinetics of poliovirus and to study whether EMA-qPCR can assess the viral infectivity after ozone disinfection. METHODS Ozone disinfection of poliovirus was conducted in the developed CQF, and the disinfection kinetics were tested in the range of 0·7-5·0 s at ozone concentration of 0·08 and 0·25 mg l-1 . Inactivation, damage on viral genome and damage on capsid integrity were determined by plaque assay, quantitative reverse transcription polymerase chain reaction (RT-qPCR) and ethidium monoazide treatment coupled with RT-qPCR (EMA-qPCR), respectively. RESULTS By using CQF, 2·18 and 2·76 log10 reductions were observed at the reaction time of 0·7 s and ozone concentration of 0·08 and 0·25 mg l-1 , respectively, followed by tailing. Ozone disinfection kinetics of poliovirus 1 were better fit by the efficiency factor Hom model than by the Chick-Watson model, or the modified Chick-Watson model. Kinetics observed were similar between RT-qPCR and EMA-qPCR assays at the reaction times of <2·0 s and ozone concentrations of 0·08 and 0·25 mg l-1 . At reaction times > 5 s, viral concentration evaluated by EMA-qPCR was reduced in comparison to stable RT-qPCR results. Both assays still underestimated the virus inactivation. CONCLUSION The simple developed reactor can be used to investigate viral ozone disinfection kinetics and to elucidate inactivation characteristics or mechanisms at very short exposure times. SIGNIFICANCE AND IMPACT OF THE STUDY The developed CQF reactor is beneficial for better understanding of virus inactivation by ozone, and the reactor can be used to better elucidate disinfection kinetics and mechanisms for future research. This work constitutes an important contribution to the existing knowledge of the application and limitation of the EMA/PMA-qPCR to assess virus infectivity after ozone disinfection.

Abstract
BACKGROUND Gemcitabine plus cisplatin (GC) is the standard treatment of advanced biliary tract cancer (BTC); however, it causes nausea, vomiting, and anorexia, and requires hydration. Gemcitabine plus S-1 (GS) reportedly has equal to, or better, efficacy and an acceptable toxicity profile. We aimed to confirm the non-inferiority of GS to GC for patients with advanced/recurrent BTC in terms of overall survival (OS). PATIENTS AND METHODS We undertook a phase III randomized trial in 33 institutions in Japan. Eligibility criteria included chemotherapy-naïve patients with recurrent or unresectable BTC, an Eastern Cooperative Oncology Group Performance Status of 0 - 1, and adequate organ function. The calculated sample size was 350 with a one-sided α of 5%, a power of 80%, and non-inferiority margin hazard ratio (HR) of 1.155. The primary end point was OS, while the secondary end points included progression-free survival (PFS), response rate (RR), adverse events (AEs), and clinically significant AEs defined as grade ≥2 fatigue, anorexia, nausea, vomiting, oral mucositis, or diarrhea. RESULTS Between May 2013 and March 2016, 354 patients were enrolled. GS was found to be non-inferior to GC [median OS: 13.4 months with GC and 15.1 months with GS, HR, 0.945; 90% confidence interval (CI), 0.78-1.15; P = 0.046 for non-inferiority]. The median PFS was 5.8 months with GC and 6.8 months with GS (HR 0.86; 95% CI 0.70-1.07). The RR was 32.4% with GC and 29.8% with GS. Both treatments were generally well-tolerated. Clinically significant AEs were observed in 35.1% of patients in the GC arm and 29.9% in the GS arm. CONCLUSIONS GS, which does not require hydration, should be considered a new, convenient standard of care option for patients with advanced/recurrent BTC. CLINICAL TRIAL NUMBER This trial has been registered with the UMIN Clinical Trials Registry (http://www.umin.ac.jp/ctr/index.htm), number UMIN000010667.

Abstract
INTRODUCTION Atypical femoral fractures are atraumatic or minimally traumatic fractures and rare side effects of bone resorption inhibitors. Bone resorption inhibitors are frequently used in the treatment of prostate cancer. CASE PRESENTATION A 62-year-old man complained of difficulty in walking and left lower limb pain. Androgen deprivation and denosumab therapy for prostate cancer-induced bone metastasis was initiated 27 months ago. Even though the prostate-specific antigen level did not increase, imaging studies indicated the possibility of bone metastasis. The patient underwent bone biopsy; however, no malignancy was detected. Afterward, he had a fall, causing a complete fracture in his left femur. CONCLUSION Atypical femoral fractures occasionally mimic typical imaging findings and outcomes of bone metastasis. This case is important for recognizing such cases.

Abstract
Direct quantitative assessment of health risks following exposure to ionizing radiation is based on findings from epidemiological studies. Populations affected by nuclear bomb testing are among those that allow such assessment. The population living around the former Soviet Union's Semipalatinsk nuclear test site is one of the largest human cohorts exposed to radiation from nuclear weapons tests. Following research that started in the 1960s, a registry that contains information on more than 300,000 individuals residing in the areas neighboring to the test site was established. Four nuclear weapons tests, conducted from 1949 to 1956, resulted in non-negligible radiation exposures to the public, corresponding up to approximately 300 mGy external dose. The registry contains relevant information about those who lived at the time of the testing as well as about their offspring, including biological material. An international group of scientists worked together within the research project SEMI-NUC funded by the European Union, and concluded that the registry provides a novel, mostly unexplored, and valuable resource for the assessment of the population risks associated with environmental radiation exposure. Suggestions for future studies and pathways on how to use the best dose assessment strategies have also been described in the project. Moreover, the registry could be used for research on other relevant public health topics.

Abstract
Abstract
The AURKA gene, encoding Aurora kinase-A (Aurora-A), is frequently amplified and overexpressed across multiple cancer types correlating with poor prognosis. Although the AURKA gene is frequently amplified in human cancers, underlying mechanism(s) for Aurora-A protein stability through different phases of cell cycle are not well elucidated. Inhibiting the kinase activity and promoting protein degradation are two well-validated conceptual strategies for targeting protein kinases in cancers. Here, we demonstrate that Eukaryotic Elongation Factor 1 Alpha 2 (eEF1A2) facilitates PTEN-GSK3β mediated Aurora-A protein degradation through the SCF complex (SKP1-Cul1-FBXW7) during the S/G2 phase of proliferating cells. In contrast, this mechanism is inactivated in cancer cells accompanying PTEN-GSK3β pathway deficiency. Mechanistically, eEF1A2 interacts with Aurora-A, GSK3β, FBXW7 and Cul1-E3 ligase, as the SCF complex, to facilitate Aurora-A polyubiquitination for 26S proteasomal degradation. eEF1A2 promotes PTEN phosphorylation at T366 and stability, inactivates AKT and activates GSK3β which in turn phosphorylates Aurora-A at S283, S284 and S342. The phosphorylation of Aurora-A at S342 is detected during S/G2 phase of cell mitosis in parallel with eEF1A2-SCF complex formation with active form of GSK3β and neddylated Cul1. Conversely, genetic ablation of EEF1A2 and PTEN, activation of AKT, inhibition of GSK3β, expression of Aurora-A phosphodeficient-mutant attenuates the Aurora-A protein degradation which is corroborated in Aurora-A overexpressing mouse mammary carcinomas and human breast carcinomas. This study identifies a novel mechanism of Aurora-A protein degradation mediated eEF1A2-PTEN-GSK3β pathway and provides a framework for the discovery of Aurora-A therapeutic targets in breast cancer that harbors deficiency of PTEN tumor suppressor pathway.

Abstract
Abstract
Background: The AURKA gene encoding Aurora kinase-A (Aurora-A) protein is localized on chromosome 20q13 that is frequently amplified and overexpressed across multiple cancer types correlating with patient prognosis. Aurora-A plays a pivotal role in faithful segregation of chromosomes and normal progression of mitosis, peaking at G2/M followed by degradation at the end of mitosis by APC/C (Cdh1). However, regulation of Aurora-A protein stability in human cancer cells is not well elucidated. Here, we show that Aurora-A is targeted for ubiquitination and degradation by SCF complex involving eEF1α2 and PTEN in human breast cancer cells. Methods: Using a panel of breast cancer cell lines, as in vitro models, the eEF1α2 was knocked down or ectopically expressed to test the stability of Aurora-A protein. For in vivo models, tissue micro arrays of human breast cancer were immunostained for Aurora-A and eEF1α2 expression and categorized values were statistically tested by Chi-squared test. In addition, the public breast cancer dataset (Transbig) was used to predict breast cancer prognosis by Kaplan-Meier survival analysis. Results: In breast cancer cell lines and patient samples, an eEF1α2 non-expressing group showed a trend of higher Aurora-A expression than eEF1α2 expressing group, whose trend was significant in patient samples (P<0.05). Knocking down of eEF1α2 enhanced Aurora-A protein stability. In contrast, ectopic expression of eEF1α2 dramatically decreased Aurora-A protein stability. Inhibition of proteasome activity by MG132 could restore the Aurora-A protein in eEF1α2 expressing cells. Biochemical assays showed the direct binding between eEF1α2 and Aurora-A, and eEF1α2 dependent ubiquitination of Aurora-A. Inverse correlation of the expression levels of the two proteins was also observed throug the cell cycle, with eEF1α2 levels being high from G1 through G2 phases while Aurora-A expression peaked from G2/M phase through cytokinesis. Taken together, these findings highlight eEF1α2 as a novel negative regulator destabilizing Aurora-A through ubiquitin-proteasome proteolytic pathway. Further, mechanistic studies revealed that eEF1α2 enhanced the interaction of SCF E3 ubiquitin ligase complex protein; FBXW7 and Cul1, with Aurora-A. In line with this scenario, knocking down of Cul1 increased Aurora-A level. Since PTEN loss was reported to stabilize Aurora-A through inhibiting SCF complex, we tested the significance of PTEN loss in our model. Knocking down of PTEN further stabilized Aurora-A suggesting an independent role of PTEN from eEF1α2 in destabilizing Aurora-A. When eEF1α2 expressing cells were treated with AKT inhibitor, Aurora-A was destabilized with enhanced bindings between Aurora-A and FBXW7/Cul1. Lastly, low PTEN expression correlated with poor prognosis of Aurora-A over expressing breast cancer patients (P<0.01). Conclusions: Aurora-A overexpression in human breast cancer cells may be associated with loss of eEF1α2 and PTEN due to reduced interaction of SCF with Aurora-A. Findings indicate significant prognostic and therapeutic implications of altered expression of eEF1α2/PTEN/Aurora-A pathways among Aurora-A subset of breast cancer patients.

Abstract
We report a histologically pure stage 1 seminoma with an elevated human chorionic gonadotropin (hCG). A 38 year-old man was referred for the evaluation of the left testicular swelling. He showed an elevated serum hCG level of 25,265 mIU/ml with normal a fetoprotein and lactate dehydrogenase. Imaging showed heterogeneous tumor without any metastatic lesions. We conducted 4 courses of chemotherapy before detecting hCG nadir. The final pathological report showed pure seminoma with syncytiotrophoblastic cells but no choriocarcinoma components. The patient remains disease free until present time. The case raised several questions regarding diagnosis and treatment strategy for bulky testicular seminoma.

Abstract
We report two cases of vein of Galen aneurysmal dilatation (VGAD) and four cases of vein of Galen aneurysmal malformation (VGAM) with special reference to clinical features and therapeutic indications of endovascular treatment. A case with VGAD was treated by radiosurgery in 1985 with no amelioration to the patient, A case of choroidal type VGAM underwent an operation in 1987, but died of massive hemorrhage 2 years later. The other case of VGAD has been followed-up conservatively. The remaining cases of VGAM (two choroidal type and one mural type) were treated by endovascular treatment. The two cases of choroidal type were successfully embolized but died of systemic complications, and the only case of mural type was cured.

Abstract
The damage to a viral capsid after low-pressure (LP) and medium-pressure (MP) UV irradiation was assessed, using the quantitative or quantitative reverse transcription PCR coupled with ethidium monoazide treatment (EMA-PCR). After UV irradiation, adenovirus 5 (Ad5) and poliovirus 1 (PV1) were subjected to a plaque assay, PCR, and EMA-PCR to investigate the effect of UV irradiation on viral infectivity, genome damage, and capsid damage, respectively. The effectiveness of UV wavelengths in a viral genome and capsid damage of both PV1 and Ad5 was also further investigated using a band-pass filter. It was found that an MPUV lamp was more effective than an LPUV lamp in inactivating Ad5, whereas there was no difference in the case of PV1. The results of viral reduction determined by PCR and EMA-PCR indicated that MP UV irradiation damaged Ad5 capsid. The damage to PV1 and Ad5 capsid was also not observed after LP UV irradiation. The investigation of effects of UV wavelengths suggested that UV wavelengths at 230-245 nm have greater effects on adenovirus capsid in addition to viral genome than UV wavelengths beyond 245 nm.

Abstract
Case 1. A 48-year-old man with no history of hypertension was referred to our hospital with a 1 cm bladder tumor. According to cystoscopy, magnetic resonance imaging and 131I-MIBG scintigraphy, we diagnosed it as a paraganglioma of the bladder. Partial cystectomy was performed. The histological findings supported the diagnosis of paraganglioma of the bladder. Six years later, he was free of any evidence of recurrence. Case 2. A 64-year-old woman with hypertension was pointed out to have a 1cm bladder mass by ultrasound in a health examination. She was referred to our hospital for further examination. Cystoscopoy revealed a 1 cm intramural nodule covered by intact urothelium at the right posterior wall. Submucosal bladder tumor was not diagnosed as paraganglioma by cold punch biopsy. So, transurethral resection of the bladder tumor was performed for differential diagnosis. The tumor was hypervascular and involved the muscular layer of the bladder. Although a transient elevation of blood pressure occurred during the procedure, the tumor was resected as completely as possible. The histological diagnosis was paraganglioma of the bladder. She has been followed up for 27 months after operation without any evidence of recurrence.

Abstract
Primary amyloidosis localized in the urinary bladder is comparatively rare,and 40% of the patients complain of lower urinary tract symptoms (LUTS). Although standard management for amyloidosis localized in the urinary bladder is not established,transurethral resection (TUR) is performed in most of the cases to diagnose the disease and to control bleeding. TUR is not considered as radical therapy for amyloidosis localized in the urinary bladder because of frequent recurrence. Dimethyl sulfoxide (DMSO) administered through intravenous,percutaneous or intravesical route has been shown to be effective for treating and preventing recurrence of the disease,but its effect on LUTS due to amyloidosis localized in the urinary bladder has not been demonstrated. We report a case showing improvement of LUTS and in which recurrence of amyloidosis localized in the urinary bladder was prevented for 18 months by intravesical DMSO therapy.

Abstract
We have visualized by cryo-electron microscopy (cryo-EM) the complex of the anthrax protective antigen (PA) translocon and the N-terminal domain of anthrax lethal factor (LF(N) inserted into a nanodisc model lipid bilayer. We have determined the structure of this complex at a nominal resolution of 16 Å by single-particle analysis and three-dimensional reconstruction. Consistent with our previous analysis of negatively stained unliganded PA, the translocon comprises a globular structure (cap) separated from the nanodisc bilayer by a narrow stalk that terminates in a transmembrane channel (incompletely distinguished in this reconstruction). The globular cap is larger than the unliganded PA pore, probably due to distortions introduced in the previous negatively stained structures. The cap exhibits larger, more distinct radial protrusions, previously identified with PA domain three, fitted by elements of the NMFF PA prepore crystal structure. The presence of LF(N), though not distinguished due to the seven-fold averaging used in the reconstruction, contributes to the distinct protrusions on the cap rim volume distal to the membrane. Furthermore, the lumen of the cap region is less resolved than the unliganded negatively stained PA, due to the low contrast obtained in our images of this specimen. Presence of the LF(N) extended helix and N terminal unstructured regions may also contribute to this additional internal density within the interior of the cap. Initial NMFF fitting of the cryoEM-defined PA pore cap region positions the Phe clamp region of the PA pore translocon directly above an internal vestibule, consistent with its role in toxin translocation.

Abstract
We have devised a procedure to incorporate the anthrax protective antigen (PA) pore complexed with the N-terminal domain of anthrax lethal factor (LFN ) into lipid nanodiscs and analyzed the resulting complexes by negative-stain electron microscopy. Insertion into nanodiscs was performed without relying on primary and secondary detergent screens. The preparations were relatively pure, and the percentage of PA pore inserted into nanodiscs on EM grids was high (∼43%). Three-dimensional analysis of negatively stained single particles revealed the LFN -PA nanodisc complex mirroring the previous unliganded PA pore nanodisc structure, but with additional protein density consistent with multiple bound LFN molecules on the PA cap region. The assembly procedure will facilitate collection of higher resolution cryo-EM LFN -PA nanodisc structures and use of advanced automated particle selection methods.

Abstract
Abstract
Aurora kinase-A (referred to as Aurora-A) identified as a sereine/threonine kinase induces mitotic progression process including centrosome amplification, bipolar spindle formation and chromosome segregation through modulation of activity and localization of its interacting proteins during cell division. Beside its essential roles in mitosis, cancer profiling studies have revealed that Aurora-A function is implicated in tumor relevant signaling pathways and overexpressed in many human tumors. The findings showed highly frequent overexpression of Aurora-A in human breast ductal carcinoma in situ and primary invasive ductal breast carcinoma. Moreover, the Aurora-A overexpression correlates with poor prognosis in breast carcinoma, deregulated overexpression of Aurora-A associates with centrosome anomalies and chromosome instability in rodent models of mammary caricinogenesis.
However, published studies in several transgenic mouse models attempting to address the role of Aurora-A in tumorigenesis and genomic instability have raised conflicting results. In this report we targeted expression of Aurora-A transgene in an inducible mouse model in which expression of Aurora-A was restricted to mammary epithelium during multiple pregnancy and lactation cycles under the activity of β-lactoglobulin promotor. The results demonstrate that overexpression of Aurora-A could induce tumorigenesis in mouse mammary epithelium. The tumor incidence was 70% of Aurora-A transgenic mice at 16 months of age. Of note, overexpression of Aurora-A led to genomic instability. Comparative genomic hybridization (CGH) array analyses revealed loss of Trim12a, Trim12c, Trim30b, Trim30d, Trim30e, Cdkn2d, Pten, Cep55 and gain of Adam6. Notably, Aurora-A overexpression caused nuclear accumulation of cyclin D1, activation of AKT, overexpression of TPX2 and PLK1and loss of ERα expression in tumors. Our findings indicated that prolonged Aurora-A expression in mammary epithelium leads to mammary adenocarcinomas with genomic instability. Aurora-A driven adenocarcinoma reveals deregulation of critical tumor relevant genetic pathways involving both oncogenes and tumor suppressor genes. These transgenic mouse model findings indicate that Aurora-A may be an important therapeutic target for mammary cancer.

Abstract
AIMS To evaluate and compare the reductions of human viruses and F-specific coliphages in a full-scale wastewater treatment plant based on the quantitative PCR (qPCR) and plate count assays. METHODS AND RESULTS A total of 24 water samples were collected from four locations at the plant, and the relative abundance of human viruses and F-RNA phage genogroups were determined by qPCR. Of the 10 types of viruses tested, enteric adenoviruses were the most prevalent in both influent and effluent wastewater samples. Of the different treatment steps, the activated sludge process was most effective in reducing the microbial loads. Viruses and F-RNA phages showed variable reduction; among them, GI and GIII F-RNA phages showed the lowest and the highest reduction, respectively. CONCLUSIONS Ten types of viruses were present in wastewater that is discharged into public water bodies after treatment. The variability in reduction for the different virus types demonstrates that selection of adequate viral indicators is important for evaluating the efficacy of wastewater treatment and ensuring the water safety. SIGNIFICANCE AND IMPACT OF THE STUDY Our comprehensive analyses of the occurrence and reduction of viruses and indicators can contribute to the future establishment of appropriate viral indicators to evaluate the efficacy of wastewater treatment.
