Abstract
Most human cancers show chromosomal instability (CIN), but the precise mechanisms remain uncertain. Annexin A2 is frequently overexpressed in human cancers, and its relationship to tumorigenesis is poorly understood. We found that annexin A2 is overexpressed in the nuclei of CIN cells compared with cells with microsatellite instability (MIN). Ectopic annexin A2 expression in MIN cells results in a high level of aneuploidy and induces lagging chromosomes; suppression of annexin A2 in CIN cells reduces such CIN signatures with apoptosis of highly aneuploid cells. Ectopic expression of annexin A2 in MIN cells reduces the expression of centromere proteins. Conversely, annexin A2-knockdown in CIN cells increases the expression of centromere proteins. Moreover, the endogenous expression levels of centromere proteins in CIN cells were greatly reduced compared with MIN cell lines. The reduced expression of centromere proteins likely occurred due to aberrant centromere localization of coilin, a major component of the Cajal bodies. These results suggest that nuclear accumulation of annexin A2 has a crucial role in CIN by disrupting centromere function.

Abstract
OBJECTIVES The control of sleep/wakefulness is associated with the regulation of energy metabolism. The present experiment was designed to assess the effect of nocturnal blue light exposure on the control of sleep/wakefulness and energy metabolism until next noon. METHODS In a balanced cross-over design, nine young male subjects sitting in a room-size metabolic chamber were exposed either to blue LEDs or to no light for 2 h in the evening. Wavelength of monochromatic LEDs was 465 nm and its intensity was 12.1 μW/cm(2). RESULTS During sleep, sleep architecture and alpha and delta power of EEG were similar in the two experimental conditions. However, the following morning, when subjects were instructed to stay awake in a sitting position, duration judged as sleep at stages 1 and 2 was longer for subjects who received than for those who received no light exposure. Energy metabolism during sleep was not affected by evening blue light exposure, but the next morning energy expenditure, oxygen consumption, carbon dioxide production and the thermic effect of breakfast were significantly lower in subjects who received blue light exposure than in those who received no light exposure. CONCLUSIONS Exposure to low intensity blue light in the evening, which does not affect sleep architecture and energy metabolism during sleep, elicits drowsiness and suppression of energy metabolism the following morning.

Abstract
To investigate the effects of L-serine intake on human sleep, we conducted two randomized double-blinded crossover studies. In Study 1, healthy subjects who were dissatisfied with their sleep were given L-serine or a placebo 30 min before going to bed. After waking the next morning, subjective sleep quality was rated using the Ogri-Shirakawa-Azumi subjective sleep rating scale. In Study 2, subjective sleep quality was rated using the St. Mary's Hospital sleep questionnaire, and objective parameters, including sleep initiation time, number of nighttime awakenings, and hours of sleep, were evaluated using actigraphy. In Study 1, factors related to "sleep initiation" and "sleep maintenance" during the L-serine intake period were significantly improved compared to the placebo intake period (p = 0.02 and p = 0.008, respectively). In Study 2, scores for "How well did you sleep last night?" and "How satisfied were you with last night's sleep?" were significantly better during L-serine intake compared to placebo (p = 0.04 and p = 0.03, respectively). Subjective evaluation of sleep quality on waking was thus improved. In addition, objective evaluation using actigraphy showed that the "number of nighttime awakenings" tended to be decreased (p = 0.08). These findings suggest that intake of L-serine before going to bed may improve human sleep.

Abstract
WHAT IS KNOWN AND OBJECTIVE The pharmacokinetics of zolpidem and brotizolam is affected by gender and age, that is, increased clearance in males taking zolpidem and younger subjects taking brotizolam. The purpose of this study was to determine the variables including gender and age influencing patient satisfaction for hypnotics, zolpidem and brotizolam. METHODS The study included 329 patients who were treated with zolpidem (n = 172) and brotizolam (n = 157) for insomnia. Patients were interviewed to evaluate individual satisfaction and drug efficacy. The factors associated with dissatisfaction of zolpidem and brotizolam were identified using multiple logistic analysis. RESULTS AND DISCUSSION Of the participating patients, 40 (23%) and 41 (26%) complained of dissatisfaction with zolpidem and brotizolam, respectively. An insufficient amount of sleep (<6 h) and the number of awakenings were common factors cited for dissatisfaction for both drugs. Males were found to report a higher rate of dissatisfaction for zolpidem, whereas patients younger than 65 years and those receiving corticosteroid therapy reported a higher rate of dissatisfaction with brotizolam. WHAT IS NEW AND CONCLUSION These results suggested that patient satisfaction was different between zolpidem and brotizolam in terms of gender for zolpidem and age and corticosteroid co-administration for brotizolam, which could be used to help choose a better drug among the two in patients with insomnia.

Abstract
The majority of human cancer shows chromosomal instability (CIN). Although the precise mechanism remains largely uncertain, proper progression of mitosis is crucial. B-type lamins were suggested to be components of the spindle matrix of mitotic cells and to be involved in mitotic spindle assembly; thus, B-type lamins may contribute to the maintenance of chromosome integrity. Here, using a proteomic approach, we identified lamin B2 as a novel protein involved in CIN. Lamin B2 expression decreased in colorectal cancer cell lines exhibiting CIN, as compared with colorectal cancer cell lines exhibiting microsatellite instability (MIN), which is mutually exclusive to CIN. Importantly, lamin B2 knockdown in MIN-type colorectal cancer cells induced CIN phenotypes such as aneuploidy, chromosome mis-segregation and aberrant spindle assembly, whereas ectopic expression of lamin B2 in CIN-type colorectal cancer cells prevented their CIN phenotypes. Additionally, immunohistochemical analysis showed a lower expression of lamin B2 in cancer tissues extracted from patients with sporadic colorectal cancer (CIN-type) than that from patients with hereditary non-polyposis colorectal cancer (HNPCC; MIN type). Intriguingly, mitotic lamin B2 in MIN cancer cells was localized outside the spindle poles and mitotic lamin B2 localization was diminished in CIN cancer cells, suggesting an important role of lamin B2 in proper mitotic spindle formation. The obtained results suggest that lamin B2 maintains chromosome integrity by ensuring proper spindle assembly and that its downregulation causes CIN in colorectal cancer.

Abstract
OBJECTIVE To evaluate the therapeutic efficacy of AxdAdB-3 with Arg-Gly-Asp (RGD)-fiber modification (AxdAdB3-F/RGD), which enables integrin-dependent infection in bladder cancers. METHODS Flow cytometric analysis was applied to evaluated adenovirus-mediated gene transduction into various cells. The cytopathic effects of AxdAdB3-F/RGD were evaluated in bladder cancer cell lines and a normal bladder mucosa-derived cell line (HCV29) with AxCAZ3-F/RGD (control) or AxdAdB-3. The efficacy of bladder instillation therapy with AxdAdB3-F/RGD for orthotopic bladder cancer was investigated in nude mice. RESULTS Expression of coxsackievirus adenovirus receptor (CAR) and integrins (αvβ3 and αvβ5) vary in different bladder cancer cell lines. The susceptibility of various cell lines to adenovirus was associated with the expression of CAR. AxdAdB-3 was more cytopathic in CAR-positive bladder cancer cells than in CAR-negative cells, whereas AxdAdB3-F/RGD caused effective oncolysis in both CAR-positive and CAR-negative bladder cancer cells. AxdAdB3-F/RGD was not cytotoxic to HCV29 cells. Direct instillation of AxdAdB3-F/RGD into the bladder of the orthotopic model, established by CAR-deficient human bladder cancer cells, inhibited tumor growth and led to significantly elongated survival. CONCLUSION E1A and E1B double-restricted oncolytic adenovirus with RGD fiber modification has enhanced infectivity and oncolytic effects to CAR-deficient bladder cancers, suggesting the therapeutic potential of AxdAdB3-F/RGD for bladder cancers.

Abstract
We described a case of a neonate of 13 trisomy with hypoplastic aortic arch and multiple ventricular septal defect (VSD). The patient presented symptoms of congestive heart failure due to pulmonary high flow. Because of ductal patency without prostaglandin infusion, bilateral pulmonary artery banding was performed for regulation of pulmonary high flow. Surgical intervention improved the clinical symptoms of the patient and permitted the patient to be discharged. We concluded that palliative surgery for the patient contributes to improve the quality of life both the patient and the family. This is the 1st report of bilateral pulmonary artery banding for a patient with 13 trisomy.

Abstract
Obstructive sleep apnea syndrome (OSAS) is associated with recurrent nocturnal hypoxia during sleep; this hypoxia has been implicated in the pathogenesis of cardiovascular complication. However, a useful soluble factor that is sensitively correlated with OSAS severity for the diagnosis remains unidentified. We hypothesized that systemic levels of basic fibroblast growth factor (bFGF), a hypoxia-induced cytokine, were affected by nocturnal hypoxemia in OSAS patients, and we assessed whether the degree of change in the plasma bFGF concentrations before and after nocturnal hypoxia is correlated with the severity of OSAS. Thirty subjects who had suspected OSAS and had been investigated by nocturnal polysomnography (PSG) were enrolled. Plasma bFGF and vascular endothelial growth factor (VEGF) concentrations the night before PSG and the next morning were measured by sandwich enzyme-linked immunosorbent assay. Correlations between the changes in these factors and hypoxia-associated parameters for OSAS severity were analyzed. Patients with OSAS had significantly elevated levels of plasma bFGF but not VEGF and hemoglobin after rising. The degree of change in bFGF concentrations after nocturnal apnea episodes was significantly correlated with diagnostic parameters for OSAS severity. The change in plasma bFGF levels is associated with the degree of hypoxic state in OSAS patients, implying that bFGF might be a useful soluble factor for evaluating OSAS severity.

Abstract
Purpose We evaluated the efficacy of a single early intravesical instillation of pirarubicin (THP) in the prevention of bladder recurrence after nephroureterectomy for upper urinary tract urothelial carcinoma (UUT-UC). Patients and Methods From December 2005 to November 2008, 77 patients clinically diagnosed with UUT-UC from 11 institutions participating in the Tohoku Urological Evidence-Based Medicine Study Group were preoperatively enrolled in this study. Patients were randomly assigned to receive or not receive a single instillation of THP (30 mg in 30 mL of saline) into the bladder within 48 hours after nephroureterectomy. Cystoscopy and urinary cytology were repeated every 3 months for 2 years or until the occurrence of first bladder recurrence. Results Seventy-two patients were evaluable for efficacy analysis, 21 of whom had a subsequent bladder recurrence. Significantly fewer patients who received THP had a recurrence compared with the control group (16.9% at 1 year and 16.9% at 2 years in the THP group v 31.8% at 1 year and 42.2% at 2 years in the control group; log-rank P = .025). No remarkable adverse events were observed in the THP-treated group. Based on multivariate analysis, THP instillation (hazard rate [HR], 0.26; 95% CI, 0.07 to 0.91; P = .035) and open surgery (HR, 0.28; 95% CI, 0.09 to 0.84; P = .024) were independently predictive of a reduced incidence of bladder recurrence. Conclusion In this prospective randomized phase II study, a single intravesical instillation of THP seemed to reduce bladder recurrence after nephroureterectomy. A phase III, large-scale, multicenter study is needed to confirm these observations.

Abstract
BACKGROUND Recent studies have suggested an emerging link between obstructive sleep apnea (OSA) and atrial fibrillation (AF). Patients with OSA are less likely to remain in sinus rhythm after radiofrequency catheter ablation of AF. OBJECTIVE To evaluate the efficacy of appropriate treatment with continuous positive airway pressure (CPAP) on recurrences of AF after ablation. METHODS This study prospectively included 153 patients (128 men; 60 ± 9 years) who underwent extensive encircling pulmonary vein isolation for drug refractory AF. The standard overnight polysomnographic evaluation was performed 1 week after ablation, and the total duration and the number of central or obstructive sleep apnea or hypopnea episodes were examined. RESULTS Of 153 patients, 116 patients were identified as having OSA. Data regarding the use of CPAP and recurrences of AF were obtained in 82 patients. The remaining 34 patients with OSA were defined as the no-CPAP group. Polysomnography revealed no sleep-disordered breathing in 37 patients. During a mean follow-up period of 18.8 ± 10.3 months, 51 (33%) patients experienced AF recurrences after ablation. A Cox regression analysis revealed that the left atrial volume (hazard ratio [HR] 1.11; 95% confidence interval [CI] 1.01-1.23; P<.05), concomitant OSA (HR 2.61; 95% CI 1.12-6.09; P<.05), and usage of CPAP therapy (HR 0.41; 95% CI 0.22-0.76; P<.01) were associated with AF recurrences during the follow-up period. CONCLUSIONS Patients with untreated OSA have a higher recurrence of AF after ablation. Appropriate treatment with CPAP in patients with OSA is associated with a lower recurrence of AF.

Abstract
OBJECTIVE To investigate the therapeutic effects of exogenous gangliosides GM3 on human bladder cancer cell lines and the severe combined immunodeficiency mouse model of orthotopic bladder cancer. MATERIALS AND METHODS Human bladder cancer cell lines YTS-1, T24, 5637, and KK47 were used in the study. In vitro cytotoxicity of GM3 was assessed using the cell counting kit-8. Cell adhesion was determined using a spreading assay. Phosphorylation of epidermal growth factor receptor was determined by Western blotting. In vivo, the orthotopic bladder cancer model was established using severe combined immunodeficiency mice and GM3 was administered intravesically by way of a transurethral catheter. RESULTS GM3 inhibited the proliferation of all the bladder cancer cell lines tested. The addition of GM3 decreased cell adhesion and epidermal growth factor-dependent phosphorylation of epidermal growth factor receptor. Direct instillation of GM3 into the bladder of the orthotopic model significantly inhibited tumor growth. CONCLUSION Our results suggest exogenous GM3 as a potential therapeutic agent for treating bladder cancer.
