Abstract
OBJECTIVE Although lowering of low-density lipoprotein cholesterol (LDL-C) by statins is essential in treatment of coronary artery disease (CAD) patients, there is considerable residual risk of secondary coronary artery events (CAE). We examined whether microvascular dysfunction (MiD), measured by peripheral artery tonometry (PAT), can predict prognosis of CAD patients previously treated with statins. METHODS We measured log-transformed reactive hyperemia index (L_RHI) in 213 CAD patients who had already achieved LDL-C <100 by statin therapy. Patients were followed-up for secondary CAE for a median of 2.7 years. Patients were divided into two groups: L_RHI ≥ 0.54 (n = 99) and L_RHI < 0.54 (n = 114). RESULTS During follow-up, CAE occurred in 4 (4.0%) patients in the L_RHI ≥ 0.54 group and 18 (15.8%) patients in the L_RHI < 0.54 group (P = 0.006). Cox regression analysis indicated that L_RHI was an independent predictor for CAE even after adjustment by Framingham traditional risk factors (FRF; age, T-C/HDL-C ratio, systolic blood pressure, diabetes, current smoker, and gender) and estimated glomerular filtration rate (eGFR) for secondary CAE (HR 0.79, 95% CI: 0.66-0.95). ROC analysis for CAE prediction showed that the AUC for models including FRF only, FRF + eGFR, and FRF + eGFR + L_RHI were 0.60, 0.71, and 0.77, respectively. Moreover, adding eGFR to FRF only (0.63, P = 0.003) and adding L_RHI to the FRF + eGFR model were associated with significant improvement of net reclassification improvement (0.79, P = 0.007). CONCLUSION MiD measured by non-invasive PAT adds incremental predictive ability to traditional risk factors for prognosis of CAD patients successfully treated with statins.

Abstract
Neuronal migration during brain development sets the position of neurons for the subsequent wiring of neural circuits. To understand the molecular mechanism regulating the migrating process, we considered the migration of mouse precerebellar neurons. Precerebellar neurons originate in the rhombic lip of the hindbrain and show stereotypic, long-distance tangential migration along the circumference of the hindbrain to form precerebellar nuclei at discrete locations. To identify the molecular components underlying this navigation, we screened for genes expressed in the migrating precerebellar neurons. As a result, we identified the following three genes through the screening; Calm1, Septin 11, and Csde1. We report here functional analysis of one of these genes, Csde1, an RNA-binding protein implicated in the post-transcriptional regulation of a subset of cellular mRNA, by examining its participation in precerebellar neuronal migration. We found that shRNA-mediated inhibition of Csde1 expression resulted in a failure of precerebellar neurons to complete their migration into their prospective target regions, with many neurons remaining in migratory paths. Furthermore, those that did reach their destination failed to invade the depth of the hindbrain via radial migration. These results have uncovered a crucial role of Csde1 in the proper control of both radial and tangential migration of precerebellar neurons.

Abstract
Previously, the structure of the adult goat parotid salivary glands (PGs) was studied. However, little information was elucidated of the juvenile ones. This study aimed to clarify the correlations between the structure of goats' PGs and the nature of food intake among milk-suckling kids (MSKs) and diet-fed goats (DFGs). The secretory endpieces of the goats' PGs are of the pure serous type. The serous cells in MSKs showed apical accumulation of numerous secretory granules (SGs) of smaller size and of more intense positive periodic acid-Schiff reaction. Ultrastructurally, most of the SGs in the DFGs contained peripherally located inclusions that showed dense reaction products for acid phosphatase. In MSKs, the PGs showed less-developed basal infoldings, sparseness of the inter-cellular inter-digitations, fewer inter-cellular canaliculi and microvilli and also less-developed myoepithelial cells with fewer and shorter cytoplasmic processes. In conclusion, the less-developed membrane specializations and myoepithelial cells, as well as the accumulated SGs in the PGs of MSKs, suggest that it secretes less saliva with a little secretory activity than that of DFGs, which may be correlated with the reduced masticatory activity.

Abstract
Magneto-caloric effects (MCEs) measurement system in adiabatic condition is proposed to investigate the thermodynamic properties in pulsed magnetic fields up to 55 T. With taking the advantage of the fast field-sweep rate in pulsed field, adiabatic measurements of MCEs were carried out at various temperatures. To obtain the prompt response of the thermometer in the pulsed field, a thin film thermometer is grown directly on the sample surfaces. The validity of the present setup was demonstrated in the wide temperature range through the measurements on Gd at about room temperature and on Gd3Ga5O12 at low temperatures. The both results show reasonable agreement with the data reported earlier. By comparing the MCE data with the specific heat data, we could estimate the entropy as functions of magnetic field and temperature. The results demonstrate the possibility that our approach can trace the change in transition temperature caused by the external field.

Abstract
BACKGROUND The aim of this study was to compare the effect on endothelial function of increasing statin dose to add-on ezetimibe in patients with coronary artery disease (CAD) already treated with statin. METHODS AND RESULTS Two-hundred and forty-three patients with CAD and low-density lipoprotein cholesterol (LDL-C) ≥70 mg/dl even after treatment with atorvastatin (10 mg) were prospectively randomized to the ezetimibe addition (10mg) group (A10E10; n=117) or to the double atorvastatin dose (to 20 mg; A20; n=133) group for 12 weeks. Primary endpoint was change in endothelial function measured by logarithmic-scale reactive hyperemia index (L_RHI). After treatment, high-sensitivity C-reactive protein (hs-CRP) and all lipids except triglyceride and high-density lipoprotein cholesterol were significantly reduced in both groups. The mean percent changes in LDL-C for the A10E10 and A20 groups were -25.8% and -9.1%, respectively (P<0.001). L_RHI increased from 0.47 to 0.62 in the A20 group (P<0.001), but not in the A10E10 group (from 0.45 to 0.48, P=0.399). Absolute change in L_RHI was significantly higher in the A20 than A10E10 group (0.02±0.29 vs. 0.16±0.27, P<0.001). CONCLUSIONS Statin and ezetimibe have different effects on endothelial function independent from LDL-C-lowering effects.

Abstract
Humanin is a secreted bioactive peptide that is protective in a variety of death models, including cell-based neuronal death models related to Alzheimer's disease (AD). To mediate the protective effect in AD-related death models, Humanin signals via a cell-surface receptor that is generally composed of three subunits: ciliary neurotrophic factor receptor α, WSX-1 and gp130 (heterotrimeric Humanin receptor; htHNR). However, the protective effect of Humanin via the htHNR is weak (EC50=1–10 μℳ); therefore, it is possible that another physiological agonist for this receptor exists in vivo. In the current study, calmodulin-like skin protein (CLSP), a calmodulin relative with an undefined function, was shown to be secreted and inhibit neuronal death via the htHNR with an EC50 of 10–100 pℳ. CLSP was highly expressed in the skin, and the concentration in circulating normal human blood was ∼5 nℳ. When administered intraperitoneally in mice, recombinant CLSP was transported across the blood-cerebrospinal fluid (CSF)-barrier and its concentration in the CSF reaches 1/100 of its serum concentration at 1 h after injection. These findings suggest that CLSP is a physiological htHNR agonist.

Abstract
An 85-year-old woman complaining of nausea was admitted to our hospital after being found to have complete atrioventricular block. We diagnosed the patient with infective endocarditis after observing vegetation on transesophageal echocardiography (TEE) and detecting Pseudomonas aeruginosa in a blood culture. The patient had no history of intravenous drug use, instrumentation or valvular disease. Although sensitive antibiotics were administered intravenously, the second TEE performed on the 10th day demonstrated increased vegetation. The patient developed septic shock and died on the 14th day. To our knowledge, this is the first report of infective endocarditis caused by community-acquired Pseudomonas aeruginosa in Japan.

Abstract
We report a 6-year-old boy with no major disease history or allergic conditions initially presented with pneumonia, progressed to acute respiratory distress syndrome and acute myocarditis caused by pandemic 2009H1N1 influenza diagnosed with RT-PCR testing, successfully managed with mechanical ventilation and percutaneous cardiopulmonary support system. Marked transient elevation of IgE in acute phase of the disease and the subsequent diagnosis of atopic asthma in our patient suggested a possible role of an underlying allergic condition in the clinicopathological process. Critically ill 2009H1N1-infected patient with acute respiratory failure should carefully be physiologically monitored together with serial assessment of biomarkers aiming at a favorable cardiac outcome by giving the timely diagnosis and intervention.

Abstract
Podocytes cover the glomerulus and their adjacent foot processes form a principal barrier called the slit diaphragm. Podocyte dysfunctions, including podocyte loss and slit diaphragm disruptions, induce chronic kidney diseases (CKD). In this study, we analyzed the correlations between podocyte injuries and renal dysfunctions in domestic carnivores. Dogs and cats were divided into normal and CKD groups according to renal histopathology and plasma creatinine values. Immunostaining results showed that linear reactions of slit diaphragm molecules, e.g., nephrin, podocin, and ACTN4, were parallel to glomerular capillaries in all animals. However, in dogs, reactions of nephrin and ACTN4 were changed to a granular pattern in the CKD group, and their intensities significantly decreased with the number of podocytes in the glomerulus. Moreover, the expression of nephrin and ACTN4 negatively correlated with creatinine. Real-time PCR analysis showed that nephrin mRNA expression in the kidneys of CKD dogs was significantly lower than that in normal animals, and negatively correlated with creatinine. Although no significant correlation between renal dysfunction and podocyte injury was detected in cats, histoplanimetric scores of tubulointerstitial lesions in CKD cats were higher than those in both normal cats and diseased dogs. Furthermore, mRNAs of WT1 and SD molecules were detected in urine from CKD animals. In conclusion, podocyte injuries such as podocytopenia and decreased expression of nephrin and ACTN4 in the glomerulus were more strongly correlated with renal dysfunction in dogs than in cats. These findings suggest that the CKD pathogenesis, especially susceptibilities to podocyte injuries, differed between dogs and cats.

Abstract
BACKGROUND Beta blockers were shown to prevent SCD in cardiomyopathy or coronary artery disease patients. Dialysis patients show elevated mortality rates, predominantly due to cardiovascular disease. SCD is now one of the leading causes of death in this population. However, the prevention of SCD remains to be elucidated. METHODS We conducted a retrospective study of 316 patients from a database of all patients undergoing maintenance hemodialysis and followed up for 4.9 years. All patients were followed-up until death. Cox regression analysis was used to adjust the hazard ratio for beta blocker use with time until death. RESULTS SCD occurred during the study period in 3 (3.8%) patients in the beta blocker group and in 27 (11.4%) patients in the non-beta blocker group (P=0.047). Death from all causes occurred in 15 (18.8%) patients in the beta blocker group and in 97 (41.3%) patients in the non-beta blocker group (P<0.001). Kaplan-Meier curve showed that the rates of both SCD and all-cause death were lower in the beta blocker group (log-rank test, P=0.028 and P<0.001, respectively). In the Cox regression model, beta blocker use was significantly associated with lower adjusted risk of SCD (multivariate adjusted hazard ratio, 0.201; 95% confidence interval, 0.058-0.693; P=0.011). CONCLUSION In hemodialysis patients, beta blocker use was associated with lower risks of SCD and death from all causes. Thus, beta blocker use in this high-risk population may substantially improve outcome.

Abstract
BACKGROUND There have been few reports regarding treatment selection and prognosis of symptomatic aortic valve stenosis (AS) in the elderly in Japan. METHODS AND RESULTS Sixty-one patients hospitalized between January 2000 and December 2007 for symptomatic severe AS were investigated. The average observation period was 27 months. Thirty-seven patients (61%) were diagnosed with AS for the first time on hospitalization. Thirty-six patients had onset of symptoms within 1 month before admission. Thirty-six patients received aortic valve replacement (group S) and 25 received medical therapy (group M). The patients in group M were older than those in group S (84.1 ± 5.3 years vs. 74.2 ± 4.6 years, P<0.001). Maximum flow velocity measured by echocardiography was lower in group M (4.5 ± 0.3 m/s vs. 4.9 ± 0.5 m/s, P<0 .01), but there was no difference in valve area between the 2 groups (0.62 ± 0.19 cm² vs. 0.57 ± 0.15 cm², P=0.12). One-year mortality rate derived from the Kaplan-Meier curve was higher in group M than group S (53.1% vs. 6.4%, respectively). On multivariate analysis, the only independent favorable prognostic factor was aortic valve replacement (HR: 0.02, 95%CI: 0.01-0.15, P<0.01). CONCLUSIONS Medical therapy is often selected for treatment of symptomatic AS in the elderly, but the prognosis is very poor. Symptomatic severe aortic stenosis should be treated surgically, or with transcatheter aortic valve implantation in cases with high surgical risk.

Abstract
AIMS The objective of this study was to investigate the clinical and oncological outcomes of prostatectomy patients undergoing minimum incision endoscopic radical prostatectomy (MIE-RP). METHODS Between September 2005 and May 2010, 541 patients underwent MIE-RP with bilateral lymphadenectomy for clinically localized prostate cancer at Hirosaki University Hospital. The present retrospective study enrolled 375 patients who had not received neoadjuvant or adjuvant therapy. MIE-RP was performed through a 6-cm suprapubic midline incision. A 30° laparoscope was conveniently positioned on the head side of the patient for precise observation and monitoring. RESULTS The median operating time was 119 min, and the estimated blood loss was 900 ml. The most frequent perioperative complication was leakage from the vesicourethral anastomosis (6.7%), and rectal injury occurred in 1.0%. Overall, 31.2% of the patients had a positive surgical margin, including 11.1% with pT2, 52.9% with pT3 and 100% with pT4 diseases. The post-operative median follow-up period was 40.5 months (range, 2-56.5 months). The 5-year PSA-free survival rate was 71.6%. In multivariate analysis, high-risk patients (according to the D'Amico risk criteria), pathological T stage and positive surgical margins were identified as independent predictors of PSA-free survival. The limitations of this study included a retrospective study, relatively short follow-up period and single-institution nature of the study. CONCLUSIONS MIE-RP is a safe and minimally invasive procedure that may represent a reliable alternative to laparoscopic and robotic-assisted RP.

Abstract
18 Background: The presence of circulating tumor cells (CTC) in the peripheral blood is associated with short survival and, therefore, the detection of CTC is clinically useful as prognostic factors of disease outcome and/or surrogate markers of treatment response. Recent technical advances in immunocytometric analysis and quantitative real-time PCR have made possible to detect a few CTC in the blood; however, there is no sensitive assay for detecting viable CTC. We developed a new approach to visually detect live CTC among millions of peripheral blood leukocytes using telomerase-specific replication-selective adenovirus expressing green fluorescent protein (GFP). Methods: We constructed a GFP-expressing attenuated adenovirus, in which the telomerase promoter regulates viral replication (OBP-401, TelomeScan). The detection method for viable human CTC in the peripheral blood involves a three-step procedure including the lysis of red blood cells, the subsequent addition of OBP-401 to the cell pellets, and the automated scan under the fluorescent microscope. We analyzed fresh blood samples collected from 37 patients with histologically confirmed gastric cancer. We further assessed the CTC dynamics in patients who were undergoing chemotherapy or surgery to demonstrate the clinical potential of our approach for monitoring treatment responses. Results: OBP-401 increased the signal-to-background ratio as a tumor-specific probe, because the fluorescent signal can be amplified only in viable human tumor cells by viral replication. Although the CTC level varied widely, ranging from 0 to 47 in 5-ml samples, 26 gastric cancer patients (70.3%) had more than one CTC; there was, however, no apparent relationship between CTC counts and TNM stages. Patients who had a recurrence of gastric cancer had decreased CTC counts after systemic chemotherapy. In the patients who underwent surgery, the CTC level dropped after complete resection. Conclusions: This GFP-expressing virus-based method is simple and allows precise enumeration of CTC, which might be useful for monitoring the efficacy of local and systemic treatments.
