Abstract
OBJECTIVE Adrenocortical carcinoma is a rare condition, with limited comprehensive reports from Japan. This study aimed to review Japan's data on adrenocortical carcinoma by assessing information from 46 patients-with adrenocortical carcinoma across 10 Japanese university hospitals. METHODS We conducted a retrospective multi-institutional analysis of the clinical characteristics of adrenocortical carcinoma in Japan. We evaluated data from 46 patients across 10 university hospitals over 10 years and analyzed the relationship between clinicopathological characteristics and overall survival. RESULTS Five- and 10-year overall survival rates were 59% and 53%, respectively. Overall survival was significantly different among the tumor-node-metastasis system for adrenocortical carcinoma of the American Joint Committee on Cancer/International Union Against Cancer, with the worst prognosis in stage IV (p = 0.0044). In our cohort, neither the Weiss score nor the Ki-67 proliferation index correlated with overall survival. Adjuvant treatment did not yield improved overall survival, whereas resection of the primary tumor in stage IV disease was significantly associated with improved overall survival (p = 0.0262). Out of the cases evaluated for plasma hormones, plasma cortisol, aldosterone, testosterone, and DHEA-S levels were measured at 23%, 42%, 29%, and 62%, respectively, demonstrating higher levels than the upper normal limits. CONCLUSION Patients with stage IV adrenocortical carcinoma had a poor prognosis; however, resection of the primary tumor in stage IV disease was associated with prolonged survival. The results of this study are expected to contribute to future treatment of adrenocortical carcinoma in Japan.

Abstract
Leiomyomatosis and renal cell carcinoma (HLRCC) are rare autosomal dominant cancer syndromes characterized by cutaneous leiomyoma, uterine leiomyoma, and renal cell carcinoma (RCC). RCC in HLRCC is an aggressive metastatic tumor that develops at a young age. Here, we report the case of a patient with HLRCC who was diagnosed after the spontaneous rupture of a renal tumor. The patient underwent cytoreductive surgery, followed by combination therapy with the immune checkpoint inhibitor (ICI) nivolumab and cabozantinib, a tyrosine kinase inhibitor (TKI); however, no improvements were achieved.

Abstract
BACKGROUND Currently, no useful serum markers exist for clear cell renal cell carcinoma (ccRCC), making early detection challenging as diagnosis relies solely on imaging tests. Radiation exposure is also a concern due to multiple required CT examinations during treatment. Renal cell carcinoma (RCC) histological types include ccRCC and non-clear cell RCC (non-ccRCC); however, treatment response to medications varies which necessitates accurate differentiation between the two. Therefore, we aimed to identify a novel serum marker of RCC. Increased LRG1 expression in the serum has been demonstrated in multiple cancer types. However, the expression of LRG1 expression in the serum and cancer tissues of patients with RCC has not been reported. Since ccRCC is a hypervascular tumor and LRG1 is capable of accelerating angiogenesis, we hypothesized that the LRG1 levels may be related to ccRCC. Therefore, we examined LRG1 expression in sera from patients with RCC. METHODS Using an enzyme-linked immunosorbent assay, serum levels of leucine-rich-alpha-2-glycoprotein 1 (LRG1) were measured in 64 patients with ccRCC and 22 patients non-ccRCC who underwent radical or partial nephrectomy, as well as in 63 patients without cancer. RESULTS Median values of serum LRG1 and their inter-quartile ranges were 63.2 (42.8-94.2) µg/mL in ccRCC, 23.4 (17.7-29.6) µg/mL in non-ccRCC, and 36.0 (23.7-56.7) µg/mL in patients without cancer, respectively (ccRCC vs. non-ccRCC or patients without cancer: P < 0.001). C-reactive protein (CRP) levels (P = 0.002), anemia (P = 0.037), hypercalcemia (P = 0.023), and grade (P = 0.031) were independent predictors of serum LRG1 levels in ccRCC. To assess diagnostic performance, the area under the receiver operating characteristic curve of serum LRG1 was utilized to differentiate ccRCC from non-cancer and non-ccRCC, with values of 0.73 (95% CI, 0.64-0.82) and 0.91 (95% CI, 0.82-0.96), respectively. CONCLUSIONS LRG1 served as a serum marker associated with inflammation, indicated by CRP, anemia, hypercalcemia, and malignant potential in ccRCC. Clinically, serum LRG1 levels may assist in differentiating ccRCC from non-ccRCC with excellent diagnostic accuracy.

Abstract
BACKGROUND/AIM To evaluate the difference in the clinical efficacy and safety of pembrolizumab between patients with metastatic upper tract urothelial carcinoma (UTUC), which includes renal pelvic urothelial carcinoma (UC) and ureteral UC, and those with metastatic lower tract urothelial carcinoma (LTUC). PATIENTS AND METHODS A total of 752 patients who received pembrolizumab for the treatment of chemoresistant UC were retrospectively analyzed. We compared progression-free survival (PFS), overall survival (OS) and adverse events (AEs) in patients with renal pelvic UC, ureteral UC, and LTUC. RESULTS The median follow-up period was 42.5 [interquartile range (IQR)=35.1-47.4] months. The primary tumor site was in the upper tract in 362 (48.1%) patients [renal pelvis, n=219 (60.5%); ureter, n=143 (39.5%)] and in the lower tract in 390 (51.9%) patients. The estimated glomerular filtration rate before pembrolizumab treatment in the UTUC group was significantly lower than that in the LTUC group (p<0.001). The median PFS in the UTUC and LTUC groups was 3.4 months, respectively (p=0.271). The median OS in the UTUC and LTUC groups was 10.1 months and 11.7 months, respectively (p=0.195). In an analysis of UTUC divided into renal pelvic UC, ureteral UC, and LTUC, patients with renal pelvic UC had a significantly poorer prognosis in comparison to the other two groups (p=0.041). The incidence of any-grade AEs (51.7% vs. 47.9%, p=0.343) and grade ≥3 AEs (12.2% vs. 12.8%, p=0.826) in the two groups was not statistically significantly different. CONCLUSION No significant differences were found between the UTUC and LTUC groups with regard to the oncological outcomes and safety of pembrolizumab. Patients with renal pelvic UC had a significantly poorer prognosis than those with other ureteral UCs and LTUCs.

Abstract
Large adrenocortical adenomas have rarely been reported. We describe a case of a 26-year-old man who underwent an adrenalectomy for a large adrenocortical adenoma (8.6 × 7.7 cm). Although the lesion had typical malignant features on imaging, histopathological examination revealed an adrenocortical adenoma. This highlights that imaging alone may not be able to distinguish adrenocortical carcinomas from adrenal masses. In most cases, a resection should be performed for early diagnosis and management of large adrenal masses with malignant features on imaging. To our knowledge, this is the first report of a large adrenocortical adenoma diagnosed with multiple imaging investigations. A patient presented with abdominal and left flank pain. We observed an ≥8-cm lesion that appeared to be malignant on imaging. Histologically, the lesion was diagnosed as an adrenocortical adenoma. Adrenocortical adenomas with malignant imaging features must be resected. This will allow their early diagnosis and treatment.

Abstract
Congenital mid-ureteral strictures (CMS) are rare. Most congenital strictures occur at the ureteropelvic junction or ureterovesical junction, with mid-ureteral strictures accounting for only 4–5% of all cases of ureteral obstruction in children. Furthermore, there are very few reports of coexisting mid-ureteral stricture and ureterovesical junction obstruction (UVJO). Here, we report a case of coexisting UVJO and CMS. CMS was not detected on preoperative magnetic resonance imaging, and hydronephrosis remained after ureteroneocystostomy. Therefore, MRI was repeated and CMS was diagnosed, for which we performed ureteroureterostomy. Intraoperative retrograde pyelography (RGP) aids definitive diagnosis of UVJO. Ureteral strictures (CMS) are rare. Few reports of coexisting CMS and ureterovesical junction obstruction (UVJO) exist. In such cases, CMS can be overlooked on magnetic resonance imaging. Intraoperative retrograde pyelography is important for accurate diagnosis.

Abstract
Background There was no clear evidence whether the initial dose of enzalutamide affects the incidence of adverse events (AEs), and oncological outcome in patients with castration-resistant prostate cancer (CRPC). Methods The clinical charts of 233 patients with CRPC treated with enzalutamide were reviewed retrospectively. After 1:3 propensity score matching (PSM), 124 patients were divided into a reduced dose group and a standard dose group, and the prostate specific antigen (PSA) response and the incidence of AEs were compared. Results 190 patients with CRPC initiated with standard dose enzalutamide were younger and better performance status compared with 43 patients beginning with reduced dose. After PSM, the baseline characteristics were not different between the standard and the reduced dose group. In the PSM cohort, the PSA response rate was significantly lower in the reduced dose group than in the standard dose group (-66.3% and -87.4%, p = 0.02). The incidence rates of AEs were not statistically different between the groups (22.6% and 34.4%, respectively, p = 0.24). Conclusion Initiating treatment with a reduced dose of enzalutamide did not significantly decrease the incidence rate of AEs, and it showed poorer PSA response rate. There is no clear rationale for treating with a reduced initial dose of enzalutamide to reduce the incidence of AEs.

Abstract
OBJECTIVES To assess the impact of histological variants on survival and response to treatment with pembrolizumab in patients with chemo-resistant urothelial carcinoma (UC). PATIENTS AND METHODS The medical records of 755 patients with advanced UC who received pembrolizumab were reviewed retrospectively. Patients were classified into pure UC (PUC) and each variant. Best overall response (BOR) and overall survival (OS) were compared between the groups using a propensity score matching (PSM). RESULTS Overall, 147 (19.5%) patients harboured any histological variant UC (VUC). After PSM, there were no significant differences in the objective response rate (ORR, 24.5% vs 17.3%, P = 0.098) or disease control rate (DCR, 36.7% vs 30.2%, P = 0.195) when comparing patients with any VUC and PUC. Furthermore, any VUC, as compared with PUC, was associated with a similar risk of death (hazard ratio [HR] 0.90, 95% confidence interval [CI] 0.68-1.20; P = 0.482). Squamous VUC, which was the most frequent variant in the cohort, had a comparable ORR, DCR and OS as compared with PUC or non-squamous VUC. The patients with sarcomatoid VUC (n = 19) had significantly better ORR (36.8%, P = 0.031), DCR (52.6%, P = 0.032), and OS (HR 0.37, 95% CI 0.15-0.90; P = 0.023) compared to patients with PUC. CONCLUSIONS The presence of variant histology did not seem to affect BOR or OS after pembrolizumab administration in patients with chemo-resistant UC. The patients with sarcomatoid VUC achieved favourable responses and survival rates compared to PUC.

Abstract
Objective To date, there are no useful markers for predicting the prognosis of metastatic hormone-sensitive prostate cancer (mHSPC). We evaluated the effect of early changes in prostate-specific antigen (PSA) levels after androgen deprivation therapy (ADT) on castration-resistant prostate cancer (CRPC) progression and overall survival (OS) in mHSPC patients. Results In 71 primary mHSPC patients treated with ADT, the median times to CRPC and OS were 15 months and 92 months, respectively. In multivariate analysis, a Gleason score of ≥ 8 (p = 0.004), an extent of disease value (EOD) of ≥ 2 (p = 0.004), and a 3-month PSA level > 1% of the pretreatment level (p = 0.017) were independent predictors of shorter time to CRPC. The area under the receiver operating characteristic curve was feasible at 0.822. A 3-month PSA level > 1% of the pretreatment level was an independent predictor of OS (p = 0.004). Three factors were independent predictors of shorter time to CRPC. A 3-month PSA level > 1% of the pretreatment level correlated with a poor prognosis.

Abstract
The use of immune checkpoint inhibitors to treat urothelial carcinoma (UC) is increasing rapidly without clear guidance for validated risk stratification. This multicenter retrospective study collected clinicopathological information on 463 patients, and 11 predefined variables were analyzed to develop a multivariate model predicting overall survival (OS). The model was validated using an independent dataset of 292 patients. Patient characteristics and outcomes were well balanced between the discovery and validation cohorts, which had median OS times of 10.2 and 12.5 mo, respectively. The final validated multivariate model was defined by risk scores based on the hazard ratios (HRs) of independent prognostic factors including performance status, site of metastasis, hemoglobin levels, and the neutrophil‐to‐lymphocyte ratio. The median OS times (95% confidence intervals [CIs]) for the low‐, intermediate‐, and high‐risk groups (discovery cohort) were not yet reached (NYR) (NYR–19.1), 6.8 mo (5.8‐8.9), and 2.3 mo (1.2‐2.6), respectively. The HRs (95% CI) for OS in the low‐ and intermediate‐risk groups vs the high‐risk group were 0.07 (0.04‐0.11) and 0.23 (0.15‐0.37), respectively. The objective response rates for in the low‐, intermediate‐, and high‐risk groups were 48.3%, 28.8%, and 10.5%, respectively. These differential outcomes were well reproduced in the validation cohort and in patients who received pembrolizumab after perioperative or first‐line chemotherapy (N = 584). In conclusion, the present study developed and validated a simple prognostic model predicting the oncological outcomes of pembrolizumab‐treated patients with chemoresistant UC. The model provides useful information for external validation, patient counseling, and clinical trial design.

Abstract
OBJECTIVES In our multicenter study evaluating metastatic papillary renal cell carcinoma (PRCC), 29% of tumors diagnosed as PRCC in collaborative institutes were finally diagnosed as other RCCs under central review. In those tumors, mucinous tubular and spindle cell carcinoma (MTSCC) was the leading histology, followed by unclassified RCC (ucRCC). We focused on those patients with MTSCC or ucRCC. METHODS We reviewed the processes for the pathological diagnoses of nine tumors and reviewed their clinical features. RESULTS All of the MTSCCs and ucRCCs were positive for AMACR, which is frequently positive in PRCC. Mucin was demonstrated in 80% of the MTSCCs, and its presence is important for their diagnoses. One MTSCC was diagnosed as a mucin-poor variant. The presence of spindle cells with low-grade nuclei was suggestive of MTSCC, but the diagnosis of high-grade MTSCC was difficult. Four tumors were diagnosed as ucRCC by histological and immunohistochemical findings. Three of the four tumors were suspicious of ucRCC in the initial review due to atypical findings as PRCC. Sunitinib and interferon-α were effective for one MTSCC patient who survived for >5 years. Two MTSCC patients who were Memorial Sloan-Kettering Cancer Center poor risk had unfavorable prognoses. One patient with mucin-poor MTSCC had an indolent clinical course. Two of four ucRCC patients showed durable stable disease with targeted agents (TAs) and survived >3 years. CONCLUSION Some MTSCC metastases progressed very slowly and poor-risk tumors progressed rapidly. Systemic therapies including TAs showed some efficacies. Some patients who have metastatic ucRCC with microscopic papillary architecture can benefit from TAs.

Abstract
Radio frequency (RF) waves including helicon waves can readily produce high-electron-density (ne up to 1013 cm-3) plasmas with a broad range of external operating parameters. Various featured RF and helicon sources in a wide range of scales are suitable for plasma propulsion schemes. Electrodeless RF plasmas have no direct contact between electrodes and antennas, which enables long-life operation. However, one of the crucial problems is to reduce the plasma size for future applications in nano- and pico-satellites. Diagnostics of the plasma parameters in a small area should also be improved. Furthermore, to increase plasma performance, it is important to consider the radial electron density (ne) profile with an increasing upper limit, observed in high-density helicon sources due to the depletion of neutrals. This problem may be controlled by the location of neutral gas feeding and knowledge of the gas pressure distribution. Here, production of RF plasmas, with extremely small diameters from 3-mm down to 0.5-mm including 1-mm, was demonstrated, and characterization of ne and the electron temperature was performed with a collisional radiative model. Finally, to improve plasma performance such as ne and the thrust force, internal gas feeding was demonstrated using a developed Pirani gauge to measure neutral density.

Abstract
We present a 78-year-old male with renal cell carcinoma who developed myasthenia gravis complicated by myositis after nivolumab administration, which was verified by the presence of antibodies against the acetylcholine receptor. The initial symptom was posterior neck pain, and biochemical examination of blood showed elevated levels of hepatic enzymes and creatine phosphokinase. The level of antibody against the acetylcholine receptor increased 4.1-fold. His condition progressed rapidly resulting in respiratory failure 15 days after conservative therapy. The onset and progression of MG upon treating patients with the PD-1 inhibitor remains unclear. Post-marketing surveillance data are needed to establish its true incidence. Clinicians using PD-1 inhibitors should keep MG in mind so that appropriate treatment including steroid can be given as soon as possible to limit long-term morbidity and mortality.

Abstract
Urothelial carcinoma of the bladder (UCB) is potentially life-threatening; therefore, we aimed to discover a novel urine biomarker for diagnosis and prognostication of UCB. This is a retrospective case-control study. Exploration of a new biomarker using urine from 20 UCB patients in the present study revealed that urinary level of lactoferrin (LF), a multifunctional glycoprotein released from neutrophils, was higher in 11 of 15 with invasive/high-grade UCB than 5 with non-invasive one, and 2 healthy adults. We therefore focused on LF and assessed the value of urine LF normalized by urine creatinine concentration (LF/Cr) using an enzyme-linked immunosorbent assay. Diagnostic performance of urine LF/Cr was examined using urine from 92 patients with primary (newly diagnosed) untreated UCB and 166 controls without UCB, including 62 patients with pyuria, and 104 subjects without pyuria consisting of 84 patients and 20 healthy adults. However, the diagnostic accuracies were accompanied by the risk of bias. In 92 primary UCB patients, both pyuria and tumor-infiltrating neutrophils (TINs) were independent predictors for urine LF/Cr. In contrast, TINs or urine LF/Cr were independent predictors for invasive histology, whereas pyuria was not. In terms of prognostication, urine LF/Cr and nodal metastasis were independent predictors of disease-specific survival in 22 patients with muscle-invasive bladder cancer, characterized by a high mortality rate, in the Cox proportional hazards model. In conclusion, urine LF/Cr linked to TINs was a predictor of both invasive histology and prognosis in UCB. Urine LF/Cr is a potential biomarker reflecting the degree of malignancy in UCB.

Abstract
We previously demonstrated that Cry j1, the major pollen allergen of Cryptomeria japonica (Japanese cedar), transiently increases protease activity and intracellular Ca2+ concentration in cultured human keratinocytes, and delays recovery after stratum corneum barrier disruption in human skin ex vivo. Topical application of tranexamic acid or trypsin-type serine protease inhibitors accelerates barrier recovery. We hypothesized that tranexamic acid might prevent the transient protease activity increase and the barrier recovery delay induced by Cry j1. Here, we tested this hypothesis and examined the mechanism involved. In cultured human keratinocytes, knock-down of protease-activated receptor 1 (PAR-1) reduced the transient increase of calcium induced by Cry j1, whereas knock-down of PAR-2 did not. Knock-down of thrombin significantly reduced the transient increases of calcium concentration and protease activity. Tranexamic acid, soybean trypsin inhibitor, or bivalirudin (a thrombin inhibitor) also reduced the calcium elevation induced by Cry j1 and/or thrombin. Co-application of tranexamic acid or bivalirudin with Cry j1 to human skin ex vivo blocked the delay of barrier recovery. These results suggest that thrombin and PAR-1 or PAR-1-like receptor might mediate the adverse effects of Cry j1 on human epidermal keratinocytes, and could open up a new strategy for treating inflammatory skin diseases.

Abstract
We investigated the optical transmission properties of one-dimensional photonic crystal (1D-PC) microcavity structures containing the liquid-crystalline (LC) perylene tetracarboxylic bisimide (PTCBI) derivative. We fabricated the microcavity structures for this study by two different methods and observed the cavity polaritons successfully in both samples. For one sample, since the PTCBI molecules were aligned in the cavity layer of the 1D-PC by utilizing a friction transfer method, vacuum Rabi splitting energy was strongly dependent on the polarization of the incident light produced by the peculiar optical features of the LC organic semiconductor. For the other sample, we did not utilize the friction transfer method and did not observe such polarization dependence. However, we did observe a relatively large Rabi splitting energy of 187 meV, probably due to the improvement of optical confinement effect.

Abstract
Probiotics are live microorganisms ingested for the purpose of conferring a health benefit on the host. Development of new probiotics includes the need for safety evaluations that should consider factors such as pathogenicity, infectivity, virulence factors, toxicity, and metabolic activity. Clostridium butyricum MIYAIRI 588® (CBM 588®), an anaerobic spore-forming bacterium, has been developed as a probiotic for use by humans and food animals. Safety studies of this probiotic strain have been conducted and include assessment of antimicrobial sensitivity, documentation of the lack of Clostridium toxin genes, and evaluation of CBM 588® on reproductive and developmental toxicity in a rodent model. With the exception of aminoglycosides, to which anaerobes are intrinsically resistant, CBM 588® showed sensitivity to all antibiotic classes important in human and animal therapeutics. In addition, analysis of the CBM 588® genome established the absence of genes for encoding for α, β, or ε toxins and botulin neurotoxins types A, B, E, or F. There were no deleterious reproductive and developmental effects observed in mice associated with the administration of CBM 588®. These data provide further support for the safety of CBM 588® for use as a probiotic in animals and humans.

Abstract
WHAT IS KNOWN AND OBJECTIVE Antibiotic resistance has become a global public health issue. Most antibiotics are prescribed in the community, although there is less stewardship of such agents in the community compared to secondary and tertiary care. Few studies have attempted to examine the prescribing practices in General Practice and its impact on antibiotic resistance and, therefore, a study was performed in order to compare antibiotic susceptibilities of commensal viridans group streptococci (VGS) obtained from patient cohorts in General Practices (GP), who were high and low prescribers of oral antibiotics. METHOD Sixty-five patients (<1 month-81 years; 77% female: 23% male) were enrolled onto the study, and viridans group streptococci (n = 5/patient) were collected from each patient's nasal passages and oropharynx region and tested for antibiotic susceptibility against (i) tetracyclines (doxycycline); (ii) macrolides (erythromycin); (iii) β-lactams (penicillin G); and (iv) fluoroquinolones (ofloxacin & levofloxacin). RESULTS AND DISCUSSION There were no significant differences in MICs between high and low GP prescribers with doxycycline (P = 0·094), erythromycin (P = 0·122), ofloxacin (P = 0·193) and levofloxacin (P = 0·058). However, there was a significant difference between high and low GP practices with regard to penicillin G (P = 0·031). This finding is important as the β-lactams are the most commonly prescribed oral antibiotic in the community. WHAT IS NEW AND CONCLUSION This study demonstrates that high prescribing practices may lead to an altered (higher) level of resistance to these agents in the commensal VGS population, which may be important as reservoirs of antibiotic resistance determinants in subsequent horizontal gene transfer events, particularly with newly colonizing pathogens, including pneumococci. Primary care physicians should be aware that increased prescribing of antibiotics may led to increased level of penicillin resistance.

Abstract
A 51-year-old woman was admitted to our hospital for detailed examinations and medical treatment against the right retroperitoneum tumor and liver lesions. Computed tomography showed a 20 cm diameter enhanced mass in the right perirenal space and multiple liver metastases. Pathological examination by needle biopsy revealed a perivascular epithelioid cell tumor (PEComa). With weekly administration of a mTOR inhibitor, Temsirolimus, the tumor was reduced by about 20% one month later. The maximal response was stable disease due to RECIST v 1. 1. However, shortly after the minimal response, the disease showed progression. She died about five months after the start of molecular targeted therapy. In regard to the origin of PEComa, our report is the fifth in Japan as a case of retroperitoneal origin to the best of our knowledge.

Abstract
The nucleus accumbens (NAc) plays a pivotal role in reward and aversive learning and learning flexibility. Outputs of the NAc are transmitted through two parallel routes termed the direct and indirect pathways and controlled by the dopamine (DA) neurotransmitter. To explore how reward-based and avoidance learning is controlled in the NAc of the mouse, we developed the reversible neurotransmission-blocking (RNB) technique, in which transmission of each pathway could be selectively and reversibly blocked by the pathway-specific expression of transmission-blocking tetanus toxin and the asymmetric RNB technique, in which one side of the NAc was blocked by the RNB technique and the other intact side was pharmacologically manipulated by a transmitter agonist or antagonist. Our studies demonstrated that the activation of D1 receptors in the direct pathway and the inactivation of D2 receptors in the indirect pathway are key determinants that distinctly control reward-based and avoidance learning, respectively. The D2 receptor inactivation is also critical for flexibility of reward learning. Furthermore, reward and aversive learning is regulated by a set of common downstream receptors and signaling cascades, all of which are involved in the induction of long-term potentiation at cortico-accumbens synapses of the two pathways. In this article, we review our studies that specify the regulatory mechanisms of each pathway in learning behavior and propose a mechanistic model to explain how dynamic DA modulation promotes selection of actions that achieve reward-seeking outcomes and avoid aversive ones. The biological significance of the network organization consisting of two parallel transmission pathways is also discussed from the point of effective and prompt selection of neural outcomes in the neural network.

Abstract
Single-shot detection of ultrabroadband mid-infrared spectra was demonstrated by using chirped-pulse upconversion technique with four-wave difference frequency generation in gases. Thanks to the low dispersion of the gas media, the bandwidth of the phase matching condition of the upconversion process becomes very broad and the entire mid-infrared spectrum spanning from 200 to 5500 cm(-1) was upconverted by using a 10 ps chirped pulse to visible wavelength radiation, which was detected with a conventional visible dispersive spectrometer. This method was demonstrated by the successful measurement of infrared absorption spectra of organic polymer films.

Abstract
A recombinant molecule of the full-length urease gene operon was constructed in vitro from the Japanese urease-positive thermophilic Campylobacter (UPTC) CF89-12 isolate and expressed in Escherichia coli cells. Several large deletion recombinant variants of urease subunit genes were also constructed and expressed in E. coli cells. A positive urease reaction with the log-phase cultured E. coli JM109 cells in the NiCl2-containing medium transformed with pGEM-T vector carrying the recombinant molecule of the full-length operon was detected with isopropyl-beta-D-thiogalactoside. Among the several deletion recombinant variants, each ureA-, ureB-, ureE-, ureF-, ureG- and ureH-large deficient, only ureE-large deletion variant (63% deficient) showed a positive urease reaction (approximately 15-fold). In addition, a ureE-complete deletion recombinant variant (100% deficient) constructed also showed a positive reaction of urease (approximately 18-fold). Recombinant urease subunits A and B were immunologically identified by Western blot analysis with anti-urease alpha (A) and beta (B) raised against Helicobacter pylori.

Abstract
We report a case of primary mucosa-associated lymphoid tissue (MALT)-type lymphoma of the urinary bladder, which temporarily regressed after antibiotic therapy and progressed 1 year after the treatment. The patient was a 72-year-old female with a history of recurrent cystitis. She was referred to our hospital for microscopic hematuria. Urinalysis also showed microscopic pyuria and cystoscopy revealed an erythematous and edematous submucosal lesion in the right side wall of the bladder. She was diagnosed with acute cystitis and treated with antibiotics. Cystoscopy after 2 months was normal. However, she presented with macroscopic hematuria and fever 1 year after the treatment. Computed tomography (CT) scan showed a solitary mass measuring 25×40 mm above the right ureteric orifice and right hydronephrosis. Transurethral resection was performed, and the histopathological findings were consistent with MALT-type lymphoma. No evidence of lymphoma was found on positron emission tomography-CT scan and bone marrow biopsy, and she was diagnosed with primary MALT-type lymphoma of the bladder. She was successfully treated with a combination of rituximab and radiotherapy. Since MALT-type lymphoma of the bladder sometimes regresses temporarily after antibiotic therapy, it should be followed carefully.

Abstract
Anticoagulant and antiplatelet medications are commonly used for the treatment and prevention of cardiovascular diseases. We studied 84 patients who received heparin as a bridging anticoagulant and antiplatelet therapy during the perioperative period. Hospitalization was extended for adjusting anticoagulant and antiplatelet drugs and also bleeding complications in the perioperative period. There were 25 instances of bleeding complications (29.7%) in this study. These complications mainly occurred when anticoagulant and antiplatelet medications were restarted in the postoperative period. In transurethral surgery, patients taking warfarin and antiplatelet drugs (aspirin or ticlopidine) had a statistically significant increase in bleeding complications compared to patients taking warfarin alone. We compared 51 cases of transurethral resection of bladder tumor, transurethral resection of the prostate holium laser enucleation of the prostate, nephroureterectomy and percutaneous nephrolithotomy with heparinization were compared to 692 cases with no heparinization. The heparinization group had a statistically significant longer hospitalization period and an increase in bleeding complications. There was one instance of thromboembolism (1.2%) in our series. This involved stent thrombosis of a patient who had drug-eluting stent in the left anterior descending coronary artery. She died three days postoperatively. The number of patients taking anticoagulant and/or antiplatelet drugs is predicted to increase in the future due to aging of the population. Guidelines for the management of anticoagulant and antiplatelet therapy in the urological period are considered necessary.

Abstract
AbstractThe purpose of our study was to clarify whether subtle cortisol-producing tumors, such as not only subclinical Cushing’s syndrome (SubCS) but also subclinical hypercortisolism (SH), influence the prevalence of hypertension, since numerous basic research studies have noted that glucocorticoid excess influences blood pressure.80 patients with adrenocortical adenomas (39 women and 41 men; mean age 62.1 years) were enrolled. SubCS was diagnosed using a diagnostic criteria, and SH was diagnosed as the presence of a serum cortisol level greater than 50 nmol/L following 1-mg dexamethasone suppression test (DST).SubCS, SH, or non-functioning adrenocortical adenoma (NF) was diagnosed in 14, 13, or 53 patients, respectively. The prevalence of hypertension differed significantly among the diagnoses (SubCS, 78.6%; SH, 84.6%; NF, 39.6%; P=0.002), whereas no differences in other clinical characteristics such as age, sex, or waist girth were observed. The patients with SH had an 11.7-fold increased risk (95% confidence interval: 1.9–72.7, P=0.009) and those with SubCS had a 9.5-fold increased risk (95% confidence interval: 1.9–48.3, P=0.007) for hypertension compared to those with NF using a multivariate analysis.We demonstrated that subtle cortisol-producing tumors, such as SH as well as SubCS, were an independent risk factor for hypertension. The cut-off value of the 1-mg DST would be appropriate to predict the development of hypertension.

Abstract
We report a case of bilateral renal calculi in a 1-year-old female with adenine phosphoribosyl transferase (APRT) partial deficiency. She initially visited another institution with high fever as the major complaint. Computed tomography revealed a bilateral renal stone and left hydro nephrosis. In the urine, there were 2, 8-dihydroxyadenine (DHA) crystals. An analysis of the APRT gene revealed the APRT deficiency and the genotype to be APRT*J/APRT*Q0. We performed extracorporeal shock wave lithotripsy (ESWL) under general anesthesia, and as dissolution therapy we administered Meylon through the nephrostomy and citric acid orally. The stone disappeared from her kidney. The analysis of the stone fragments revealed 2,8- dihydroxyadenine (DHA) urolithiasis.

Abstract
BACKGROUND Adiponectin is thought to play a significant role in the development of both insulin resistance and metabolic syndrome. Yet, there is very few evidence about the association plasma adiponectin and metabolic syndrome in the prospective study. Adiponectin exists as multimers in serum, and high-molecular-weight (HMW) adiponectin is particularly considered to be the active form of the protein. AIM We investigated whether serum HMW adiponectin as well as total adiponectin is associated with the development of metabolic syndrome in a longitudinal study. SUBJECTS AND METHODS We enrolled 224 men and 312 women of Japanese- Americans without metabolic syndrome at baseline who were followed for an average of 3.2 yr. The association of plasma total and HMW adiponectin with a progression to metabolic syndrome was examined. RESULTS Subjects who developed metabolic syndrome had significantly lower plasma total and HMW adiponectin levels at baseline than those who did not develop metabolic syndrome. In a Cox proportional hazards model, lower total and HMW adiponectin levels were independent risk factors for the development of metabolic syndrome after adjusting for age, body mass index, classification of 75-g glucose tolerance test, and homeostasis model assessment (hazards ratio: total, 0.684, p=0.017, in men; 0.606, p=0.003, in women; HMW, 0.687, p=0.014, in men; 0.704, p=0.029, in women, respectively). CONCLUSIONS Low circulating levels of total and HMW adiponectin may be a possible predictor for the development of metabolic syndrome.

Abstract
To assess appropriate treatment strategies for transitional cell carcinoma in situ (CIS) of the upper urinary tract (UUT), we evaluated the long-term outcome of Bacillus Calmette-Guérin (BCG) perfusion therapy for CIS of UUT. We retrospectively reviewed the medical records of 24 patients who underwent BCG perfusion therapy for CIS of UUT between August 1993 and August 2009. Patients received at least one course of BCG (once weekly for 6 weeks). The median follow-up period was 48.5 months (range 16-201 months). In 23 patients (96%), cytology became negative after one course of BCG perfusion and 12 patients (50%) remained disease-free for a median follow-up of 38. 5 months. In 11 patients positive cytology recurred, and in five of them nephroureterectomy was performed after radiologic studies showed the presence of a tumor in the UUT. Histopathology showed invasive tumor (pT3) in all cases, and three of them experienced distant metastases after surgery. In conclusion, BCG perfusion therapy is effective for the treatment of CIS of UUT with long-term follow-up. However, in cases with a poor response or recurrence of CIS, there is a high risk of developing invasive tumor. Surgical intervention should be immediately considered in such cases after the first course of BCG perfusion therapy.

Abstract
Molecular and comparative analyses of the full-length cytolethal distending toxin (cdt) gene operon and its adjacent genetic loci (2.7-9.4 kilo base pairs in length) are carried out with 12 urease-positive thermophilic Campylobacter (UPTC) isolates using several polymerase chain reaction (PCR) primer pairs. Three putative open reading frames (ORFs) for cdtA, cdtB and cdtC, two putative promoters and a hypothetically intrinsic rho-independent transcription terminator were identified in all the operons of the 12 UPTC isolates examined. Although the number of amino acid residues slightly varied for the putative cdtA and cdtC ORFs, those for the cdtB were similar among all the UPTC isolates, as well as the six urease-negative (UN) C. lari examined previously. Regarding the cdt genes in UPTC CF89-12, each ORF commenced with an ATG start codon and terminated with a TAG stop codon for cdtA and cdtB and a TAA for cdtC. Start and stop codons of the three ORFs for the other 11 UPTC isolates were identical to those from the UPTC CF89-12 isolate except for the TTG start codon for cdtC in the two isolates (NCTC12892 and 12893) and the TGA stop codon for cdtA in five isolates (A1, A2, A3, 89049 and 92251). Two putative promoter structures, consisting of sequences at the -35-like (TTAATA) and -10-like (TATTAA) regions, as well as the start codon (ATG), were identified for the transcriptional promoter, immediately upstream of the cdtA gene in all the 12 isolates, Although the genetic heterogeneity of the cdtB gene locus occurred in all 28 C. lari isolates (n = 16 UN C. lari; n = 12 UPTC) examined, all nine amino acid-specific DNase residues were completely conserved in all their cdtB genes. Variable gene insertions with heterogeneous order and combinations occurred between cdtC and lpxB genes in the all UPTC organisms examined.

Abstract
BACKGROUND Although hepatitis C virus (HCV) infection is known to be associated with Type 2 cryoglobulinemic glomerulopathy (CG), only a few reports about other types of nephropathy have been published. METHODS 68 HCV antibody positive patients in whom renal biopsy had been performed for persistent proteinuria, hematuria, and/or renal dysfunction between 1992 and 2008 at our institute were included. The histological, clinical and laboratory characteristics including the age, gender, hypertension, diabetes mellitus, liver histology (chronic hepatitis or liver cirrhosis), HCV-RNA, HCV genotype, splenomegaly, gastroesophageal varices, serum creatinine, hemoglobin, platelet count, rheumatoid factor, cryoglobulin, IgG, IgA, IgM, CH50, C3, C4, creatinine clearance, 24-h protein excretion, and hematuria, between their nephropathy with and without immune deposition were compared. RESULTS Nephropathy was classified into two groups based on the detection of immune deposits by immunofluorescence microscopy: i.e., a positive group (n = 39) and a negative group (n = 29). The former group was further classified into three types of nephropathy: IgG dominant group (n = 10) (including membranous nephropathy (MN)), IgA dominant group (n = 20) (including IgA nephropathy (IgAN)), membranoproliferative glomerulonephritis (MPGN) (IgA type)), and IgM dominant group (n = 9) (MPGN apart from the IgA type). The latter group included diabetic nephropathy (n = 13), focal glomerular sclerosis (n = 4), and benign nephrosclerosis (n = 3), malignant nephrosclerosis (n = 1), tubulointerstitial nephritis (TIN) (n = 2), minimal change nephrotic syndrome (n = 1), cast nephropathy (n = 1), granulomatous TIN (n = 1), and others (n = 3). An increased serum IgM level, hypocomplementemia, splenomegaly, thrombocytopenia, liver cirrhosis, hematuria, and a high HCV RNA level were features of patients with MPGN of IgM dominant group (consistent with "CG"). CONCLUSIONS Our results showed various histological patterns of HCV-related kidney disease and the specificity of CG, and revealed that a minority of HCV patients (n = 7) presented typical CG, while IgAN, MN, and diabetic nephropathy were more frequent.

Abstract
Two sets of PCR primers are constructed to clone the cytochrome P450 structural gene, including putative promoter and terminator structures, and its adjacent genetic loci in Campylobacter lari isolates. The putative open reading frames (ORFs) of the P450 genes from 11 C. lari isolates (n=5 for urease-negative (UN) C. lari; n=6 urease-positive thermophilic campylobacters [UPTC]) examined consisted of 1365 or 1371 bases (455 or 457 amino acid residues), differing from those of the other thermophilic campylobacters (1359 [453] for C. jejuni and C. upsaliensis; 1368 [456] for C. coli). Each of the putative ORFs from the 11 isolates examined was also shown to carry start and stop codons and ribosome binding sites. Two putative promoter structures, consisting of sequences at the -35- and -10-like regions were also identified upstream of the ORFs. A single copy of the P450 gene in the genome was identified with UN C. lari JCM2530(T) and UPTC CF89-12, based on Southern blot hybridisation analysis. In addition, when reverse transcription polymerase chain reaction (RT-PCR) analyses were carried out, the transcription of the P450 structural gene in C. lari organisms in vivo was confirmed. The transcription initiation site for the gene was also determined. High nucleotide sequence similarities (95.2-98.8%) of the full-length P450 structural gene were shown with each of the 12 C. lari isolates. The UN C. lari and UPTC organisms showed similar findings with the neighbour-joining method, based on the sequence information of the P450 structural gene.

Abstract
The cerebellar circuitry consists of two main excitatory glutamatergic pathways. The inputs of mossy fibers and climbing fibers converge on Purkinje cells and deep cerebellar nuclei. In this circuitry, Golgi interneurons suppress granule cell excitability via the inhibitory GABA transmitter. A novel technique termed reversible neurotransmission blocking (RNB) was genetically established, in which granule cell transmission to Purkinje cells was selectively and reversibly blocked in the mouse cerebellar circuitry. This study revealed that Purkinje cells are essential for expression of conditioned eye-blink motor learning but that this memory is acquired and stored in deep cerebellar nuclei. A different technique termed immunotoxin-mediated cell targeting (IMCT) was developed to selectively ablate Golgi cells from the mouse cerebellar network. The study disclosed that excitatory glutamate receptors and inhibitory GABA receptors cooperatively act at Golgi cell-mossy fiber-granule cell synapses and are indispensable for motor coordination and adaptation. Finally, gene targeting of mGluR2 displayed that the metabotropic glutamate receptor acts collaboratively with the ionotropic AMPA receptors at granule cell-Golgi cell synapses and is crucial for the spatiotemporal regulation in the mouse cerebellar circuitry. The neural information is thus hierarchically regulated and integrated at different levels of the cerebellar network.

Abstract
AIMS Recent evidence indicates that oxidative stress may play an important role in the pathogenesis of insulin resistance and that gene polymorphism (Ala16Val) of manganese superoxide dismutase (MnSOD) may protect against reactive oxygen species (ROS) function. We aimed to test the hypothesis that the Ala16Val variant could be associated with the development of type 2 diabetes. METHODS We examined 523 nondiabetic Japanese-Americans who underwent a 75g oral glucose tolerance test (OGTT) and were followed for an average of 9.9 years. Cox proportional hazard analysis, stratified by category of OGTT, was used to determine whether the Ala16Val polymorphism was a risk factor in the development of type 2 diabetes. RESULTS During the follow-up period, 65 subjects developed type 2 diabetes. Compared with Ala allele carriers, subjects with a Val homozygote showed significantly higher risk for developing diabetes (stratified hazard ratio=2.05 [95% confidence interval 1.03-4.08]; P=0.041) after adjustment for age, gender, systolic blood pressure, total cholesterol, body mass index, and homeostasis model assessment. CONCLUSIONS We demonstrated that the MnSOD Ala16Val polymorphism might be associated with development of type 2 diabetes among Japanese-Americans. These results suggest that insufficient ROS scavenging might be associated with a susceptibility to glucose intolerance.
