Abstract
A vertical external cavity surface emitting laser (VECSEL) has been developed for a sodium guide star application. Stable single frequency operation with 21 W of output power near 1178 nm with multiple gain elements while lasing in the TEM00 mode has been achieved. Higher output power results in multimode lasing. For the sodium guide star application, the 1178 nm can be frequency doubled to 589 nm. The power scaling approach used involves using multiple gain mirrors in a folded standing wave cavity. This is the first demonstration of a high power single frequency VECSEL using a twisted-mode configuration and multiple gain mirrors located at the cavity folds.

Abstract
OBJECTIVE The aim of this study is to understand whether the responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis to stress increases excessively with aging in senescence-accelerated mice-prone 10 (SAMP10) and to investigate the role of arachidonic acid (ARA) in this process. MATERIALS AND METHODS The area under the curve of CORT concentration (CORT-AUC), an index of the HPA axis responsiveness to stress, was assessed in SAMP10 subjected to a 30-minute restraint stress up to 120 minutes after the restraint stress onset. Furthermore, the HPA axis responsiveness was evaluated in aged SAMP10 fed 0.4% ARA-containing diet (ARA group) or control diet (CON group) for 4 weeks. Three weeks later, these mice were divided into a group with a 30-minute restraint stress (CON-S or ARA-S group) and a group without restraint stress (CON-NS or ARA-NS group). Hippocampi were collected after stress release and fatty acid and glucocorticoid receptor (GR) protein levels were evaluated in the nucleus and cytosol. RESULTS The CORT-AUC of aged SAMP10 was 21% significantly higher than that of young SAMP10. In the ARA group, hippocampal ARA was 0.5% significantly higher than that in the CON group. CORT-AUC in the ARA group was 24% significantly lower than that in the CON group. The ratio of GR protein levels in the nucleus and cytosol in the ARA-S group was 1.72 times significantly higher than that in the ARA-NS group but no difference was observed between the CON-S and CON-NS groups. CONCLUSIONS Dietary ARA seems to suppress age-related excessive enhancement of the HPA axis responsiveness via attenuation of age-related decline in hippocampal GR translocation into the nucleus after stress loading, which may contribute to an improvement of mental health.

Abstract
Objective : The purpose of the present study is to examine clinical factors related to life skills in people with schizophrenia. Method : The participants were 51 stabilized outpatients with schizophrenia. Their mean age was 38.91 (SD = 10.73) years. Life skills were assessed using the Life skills profile (LSP). Cognitive function was evaluated with the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB). Clinical symptoms were assessed using the Positive and Negative Syndrome scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS). Results : Cognitive function was not correlated with the LSP scores at all. Among clinical symptoms, scores of the PANSS positive and negative syndrome scales, the CDSS, and the DIEPSS had negative correlations with the LSP total score and the subscales. Stepwise regression analyses showed that the CDSS and PANSS negative syndrome scale scores were independent predictors of the LSP total score and two of the subscales. Conclusions : These results indicate that cognitive function is not associated with life skills but clinical symptoms such as depressive and negative symptoms have considerable impacts on life skills in people with schizophrenia.

Abstract
An in vitro-produced bovine embryo has a low conception rate compared with that of an in vivo embryo. The present study was conducted to examine the effects of different treatments delivered to donors before ovum pickup (OPU) sessions to improve the conception rate of in vitro-produced bovine embryos. In total, 351 OPU sessions were performed on 138 Holstein and 213 Japanese Black cows from January to December 2017. Donors were divided into 4 groups based on their pretreatment before OPU: (1) single injection of 2.5 AU of FSH 40h before OPU; (2) CIDR insertion on Day 0, injection of 2mg of oestradiol benzoate on Day 1, 4 injections of FSH (each 2.5 AU) every 12h beginning from Day 5 to 7, followed by removal of CIDR and OPU on Day 9; (3) injection of 50μg of gonadotropin-releasing hormone 72h before OPU; or (4) no pretreatment. The collected cumulus-oocyte complexes were matured for 22h in 25mM of HEPES buffered TCM-199 supplemented with 5% newborn calf serum and 0.02 AU mL−1 FSH. After 6h of gamete co-culture (5.0×106 sperm mL−1), the presumptive zygotes were washed and the remaining cumulus cells were denuded by pipetting. The presumptive zygotes were then cultured in KSOMaa supplemented with 5% newborn calf serum for 9 days in a micro-well culture dish (Dai Nippon Printing, Tokyo, Japan). Blastocyst formation rates were analysed 9 days after insemination, and the formed blastocysts were transferred to oestrous synchronized recipients on the seventh or eighth day after oestrus. The data were analysed by Chi-squared test with Yates correction. The average numbers of collected oocytes were 57.7±17.4 (n=136), 25.3±12.8 (n=20), 28.8±12.5 (n=18) and 24.3±12.9 (n=177) in groups 1 to 4, respectively. Groups 1 and 2 showed significantly (P<0.01) high percentages of Grade-1 oocytes (52.1 and 49.6%, respectively) compared with groups 3 and 4 (37.3 and 39.9%, respectively). The proportion of blastocysts in groups 1 (38.6%) was significantly different compared with that in groups 2 (32.1%) and 4 (35.3%), but the difference was insignificant in the case of group 3 (36.4%). The conception rates in groups 1 (43.5%, n=868) and 2 (59.1%, n=44) were significantly (P<0.05) higher than those in groups 3 (35.1%, n=57) and 4 (34.9%, n=768). These results suggest that although the efficiency of embryo production did not differ largely between donors pretreated with 4 FSH injections and those without any pretreatment, the conception rate in donors pretreated with 4 FSH injections was significantly higher than that in donors without pretreatment. Moreover, donors pretreated with a single injection of FSH showed significantly high efficiency of embryo production and conception rate than donors without pretreatment.

Abstract
PURPOSE The purpose of the present study was to examine clinical factors related to social function in people with schizophrenia. PATIENTS AND METHODS The participants were 55 stabilized outpatients with schizophrenia. Their mean age was 39.36 (SD =10.65) years. Social function was assessed using the Quality of Life Scale (QLS). Cognitive function was evaluated with the Measurement and Treatment Research to Improve Cognition in Schizophrenia Consensus Cognitive Battery (MCCB). Clinical symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia, and the Drug-Induced Extrapyramidal Symptoms Scale. RESULTS Neither the MCCB cognitive domain score nor composite score was correlated with the QLS scores. However, of the 10 MCCB subtests, the Trail Making Test Part A and the Brief Assessment of Cognition in Schizophrenia-Symbol Coding (BACS-SC) scores were positively correlated with the QLS scores. Among clinical variables, especially the PANSS negative syndrome scale score had a strong negative correlation with the QLS scores. Stepwise regression analyses showed that the PANSS negative syndrome scale score was an independent predictor of the QLS scores, and although the BACS-SC score predicted the QLS common objects and activities subscale score, the association was not so strong compared to the PANSS negative syndrome scale score. CONCLUSION These results indicate that speed of processing evaluated by BACS-SC could predict some aspect of social function but negative symptoms have a much stronger impact on global social function in people with schizophrenia.

Abstract
The conventional superovulation treatment using follicle-stimulating hormone (FSH) comprises 2 intramuscular injections per day for 3 to 4 days. This conventional method requires frequent handling of donors—which may cause increasing stress in donors—and high labour costs. Therefore, to alleviate these issues, a treatment protocol using a single FSH injection under on-farm conditions is needed. The objective of this study was to evaluate the feasibility of the single subcutaneous FSH injection protocol (Sugawara et al. 2017 Reprod. Fertil. Dev. 29, 209), compared with with the traditional twice-daily intramuscular FSH injection protocol, in Japanese Black cows. Japanese Black cows (n = 13) were superovulated using 2 treatments in a crossover design. All cows received an intravaginal progesterone device (CIDR) at random stages of the oestrous cycle (Day 0), and 2 mg of oestradiol benzoate on Day 1 (24 h after CIDR insertion). On Day 6, for the group receiving a single subcutaneous FSH injection (single-FSH), 20 armor units (AU) of pFSH dissolved in 30 mL of saline was subcutaneously injected in the neck region and 0.5 mg of prostaglandin F2α was intramuscularly injected simultaneously. For the control group, FSH administration was initiated at Day 6. A total dose of 20 AU of FSH was administered in 3 days (with decreasing doses of 5, 3, and 2 AU, respectively, per injection) with 2 intramuscular injections per day; 0.5 mg of prostaglandin F2α was injected 48 h after the first FSH injection. For both groups, CIDR was removed 60 h after FSH injection and AI was done 42 to 48 h after CIDR removal. Embryo collections were performed 7 days after AI. Data were analysed using t-test for the mean numbers of collected ova/embryos and transferable embryos, and chi-squared test for the proportion of transferable embryos. There were no significant differences in the mean numbers (single-FSH v. control) of ova/embryos collected (17.1 ± 12.1 v. 17.8 ± 9.3), or transferable embryos (8.4 ± 9.3 v. 10.3 ± 8.7), and proportion of transferable embryos (45.0 ± 34.0 v. 56.6 ± 36.5). These results showed that although a slightly higher number and proportion of transferable embryos were obtained in the control group, a superovulation treatment protocol involving a single subcutaneous FSH injection can be effectively used for Japanese Black cows, under on-farm conditions.

Abstract
Objective: To evaluate cognitive function impairment in patients with anorexia nervosa (AN) of either the restricting (ANR) or binge-eating/purging (ANBP) subtype. Method: We administered the Japanese version of the MATRICS Consensus Cognitive Battery to 22 patients with ANR, 18 patients with ANBP, and 69 healthy control subjects. Our participants were selected from among the patients at the Kobe University Hospital and community residents. Results: Compared to the healthy controls, the ANR group had significantly lower visual learning and social cognition scores, and the ANBP group had significantly lower processing speed, attention/vigilance, visual learning, reasoning/problem-solving, and social cognition scores. Compared to the ANR group, the ANBP group had significantly lower attention/vigilance scores. Discussion: The AN subtypes differed in cognitive function impairments. Participants with ANBP, which is associated with higher mortality rates than ANR, exhibited greater impairment severities, especially in the attention/vigilance domain, confirming the presence of impairments in continuous concentration. This may relate to the impulsivity, an ANBP characteristic reported in the personality research. Future studies can further clarify the cognitive impairments of each subtype by addressing the subtype cognitive functions and personality characteristics.

Abstract
AIM Neurocognitive impairment is one of the core symptoms of bipolar disorder (BD). The MATRICS Cognitive Consensus Battery (MCCB) is a potential consensus assessment tool to evaluate cognitive function in patients with BD. Here, we report on cognitive deficits evaluated using the MCCB Japanese version (MCCB-J) in euthymic Japanese patients with BD, and compare them with scores in previous studies. METHODS We compared neurocognitive function in 25 patients with euthymic BD and 53 healthy controls (HC). Additionally, we searched all available databases for studies that have evaluated cognitive function in BD using the MCCB, and conducted a meta-analysis. RESULTS Canonical discriminant analysis revealed significant differences in MCCB-J domain scores between BD and HC. Patients with BD performed significantly worse on visual learning, social cognition, speed of processing, and MCCB composite scores. Our meta-analysis revealed that patients with BD performed worse than HC, as reflected by MCCB composite scores and scores on all seven cognitive domains. However, there are differences in the cognitive deficits identified in previous studies compared with our participants, particularly social cognition. CONCLUSION As reported in previous studies, neurocognitive deficits were observed in Japanese euthymic BD patients assessed using the MCCB-J. Further study is needed to clarify whether differences in social cognition between this study and previous studies are a result of coping mechanisms for social settings in Japanese populations.

Abstract
Inactivated Sendai virus particles (hemagglutinating virus of Japan envelope (HVJ-E)) have a novel antitumor effect: HVJ-E fused to prostate cancer cells via cell surface receptor causes apoptosis of prostate cancer cells in vitro and in vivo. HVJ-E also induces antitumor immunity by activating natural killer (NK) cells and cytotoxic T cells and suppressing regulatory T cells in vivo. We conducted an open-label, single-arm, phase I/II clinical trial in patients with castration-resistant prostate cancer (CRPC) to determine the safety and efficacy of intratumoral and subcutaneous injection of HVJ-E. Patients with CRPC who were docetaxel-resistant or could not receive docetaxel treatment were eligible. HVJ-E was injected directly into the prostate on day 1 and subcutaneously on days 5, 8 and 12 in two 28-day treatment cycles using a 3+3 dose-escalation design. The primary end points were to evaluate safety and tolerability of HVJ-E. The secondary end points were to analyze tumor immunity and antitumor effect. The study is registered at UMIN Clinical Trials Registry, number UMIN000006142. Seven patients were enrolled, and six patients received HVJ-E. Grade 2 or 3 adverse events (Common Terminology Criteria for Adverse Events Ver. 4.0) were urinary retention and lymphopenia from which the patients recovered spontaneously. No Grade 4 adverse events were observed. Radiographically, three patients had stable disease in the low-dose group, and one patient had stable disease and two had progressive disease in the high-dose group. The prostate-specific antigen (PSA) declined from 14 to 1.9 ng ml-1 in one patient in the low-dose group after two cycles of HVJ-E treatment, and the PSA response rate was 16.6%. NK cell activity was elevated from day 12 to day 28 after HVJ-E administration, whereas serum interleukin-6, interferon (IFN)-α, IFN-β and IFN-γ levels were not affected by HVJ-E treatment. Intratumoral and subcutaneous injections of HVJ-E are feasible and PSA response was observed in a subgroup of CRPC patients.

Abstract
Superovulation treatment using FSH requires injection twice a day, for 3 to 4 days. This conventional method requires frequent handling of donors and higher labour costs. Therefore, simplification of the superovulation treatment protocol is needed to reduce animal handling and labour costs. The objective of this study was to investigate the effect of a single subcutaneous FSH injection and the timing of prostaglandin F2α (PGF; cloprostenol) administration on the superovulatory response in Japanese Black cows (Hiraizumi et al. 2015 Theriogenology 83, 466–473) and to determine whether the superovulation treatment protocol can be used in on-farm conditions. A total of 270 Japanese Black cows were used in this study. Twenty Armour units of pFSH dissolved in 30 mL of saline was injected subcutaneously in the neck region. In Experiment 1, 32 cows received an intravaginal progesterone device (CIDR) at random stages of the oestrous cycle (Day 0), and 2 mg of oestradiol benzoate on Day 1 (24 h after CIDR insertion). On Day 6, FSH was injected subcutaneously, and 16 cows were simultaneously injected with 0.5 mg of PGF (0-h PGF, Group A); the other 16 cows were injected with 0.5 mg of PGF at 48 h (on Day 8) after FSH injection (48-h PGF, Group B). The CIDR was removed at 60 h after FSH injection and AI was done 42 to 48 h after CIDR removal. Embryo collections were performed 7 days after AI. In Experiment 2, 238 cows were used in farm conditions. The cows were superstimulated using the same protocol as that used for Group A. Data were analysed by ANOVA for the mean numbers of collected ova/embryos and transferrable embryos and chi-square test for the proportion of transferrable embryos. In Experiment 1, there were no differences in the mean numbers of ova/embryos collected (16.9 ± 12.3 v. 16.1 ± 17.1) or transferrable embryos (11.1 ± 9.5 v. 7.2 ± 6.2). However, the proportion of transferrable embryos for Group A was significantly higher than that of Group B (65.9 v. 44.7%; P < 0.01). In Experiment 2, the mean numbers of ova/embryos collected and transferrable embryos were 15.7 ± 13.3 and 6.8 ± 7.8, respectively. These results showed that a superovulation treatment protocol involving a single subcutaneous injection of FSH with simultaneous PGF injection can be effectively used for Japanese Black cows under on-farm conditions.

Abstract
This study investigated the relationship between subjective and objective quality of life and assessed predictors in people with schizophrenia. The study population consisted of 99 stabilized outpatients with schizophrenia (DSM-IV) who had been regularly receiving outpatient treatment at the Department of Psychiatry, The Tokushima University Hospital. Subjective and objective quality of life were estimated using the Schizophrenia Quality of Life Scale and the Quality of Life Scale, respectively. Psychiatric symptoms were also measured with the Brief Psychiatric Rating Scale and the Calgary Depression Scale for Schizophrenia. Scores on the Schizophrenia Quality of Life Scale Motivation and Energy scales significantly correlated with the Quality of Life Scale total scores –.40 ( p <.001), and with the scores on Interpersonal Relations subscale –.42 ( p <.001), Instrumental Role subscale –.28 ( p = .005), Intrapsychic Foundations subscale –.39 ( p <.001), and Common Objects and Activities subscale –.25 ( p = .014). The Schizophrenia Quality of Life Scale Psychosocial scale significantly correlated with only the Quality of Life Scale total score –.20 ( p = .05), and there was no significant correlation between the scores on the Schizophrenia Quality of Life Scale Symptoms and Side-effects scales and the Quality of Life Scale. Stepwise regression analyses showed that the Calgary Depression Scale for Schizophrenia score was the most important predictor of each scale of the Schizophrenia Quality of Life Scale, and the Brief Psychiatric Rating Scale Negative Symptoms score was the most important predictor of the Quality of Life Scale total score and each subscale. These results suggest that subjective and objective quality of life have different predictors and should be considered as separate and complementary outcome variables.

Abstract
AIMS The purpose of this study was to evaluate the long-term effectiveness and safety of blonanserin, a second-generation antipsychotic drug developed in Japan, in patients with first-episode schizophrenia. METHODS Twenty-three antipsychotic-naïve patients with first-episode schizophrenia were treated within an open-label, 1-year, prospective trial of blonanserin (2-24 mg/day). Clinical evaluations were conducted at baseline and 2, 6, and 12 months after the start of treatment. The main outcome measures were changes in subjective well-being and subjective quality of life, as assessed by the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version and the Schizophrenia Quality of Life Scale-Japanese version, respectively. Secondary outcome measures included the Positive and Negative Syndrome Scale, the Brief Assessment of Cognition in Schizophrenia-Japanese version, laboratory tests, bodyweight, and extrapyramidal symptoms. RESULTS Fourteen patients (60.9%) remained on the study at 1 year. In the intention-to-treat analysis, significant improvements were observed in several subscales on the Subjective Well-being under Neuroleptic treatment scale Short form-Japanese version, the Schizophrenia Quality of Life Scale-Japanese version, and the Brief Assessment of Cognition in Schizophrenia-Japanese version, and in all factor scores on the Positive and Negative Syndrome Scale. Improvement in depressive symptoms with blonanserin treatment was positively correlated with improvements in subjective well-being and subjective quality of life, as well as verbal memory. No significant changes were noted for any safety measure during the 1-year study period. CONCLUSIONS Blonanserin was well tolerated and effective for the treatment of first-episode schizophrenia in terms of subjective wellness, cognition, and a wide range of pathological symptoms. Further large-scale studies are warranted to confirm our findings.

Abstract
PURPOSE This retrospective study evaluates the clinical course and outcomes of patients who underwent surgery for strangulated hernias. METHODS Among 520 groin hernias from 2001 to 2012, 51 inguinal and 42 femoral hernias were strangulated and operated emergently at a tertiary referral center. Perioperative factors, patient profiles, and time interval to surgery (T total = time from onset to surgery, T 1 = time from onset to initial evaluation, T 2 = time from the first hospital to the tertiary center, T 3 = time from admission at the tertiary center to surgery, T total = T 1 + T 2 + T 3) were analyzed in patients with strangulation, then compared between two groups, the bowel resection (BR) group and the non-bowel resection (NBR) group. RESULTS T 1, T 2 and T total in the bowel resection group were significantly longer than those in the non-bowel resection group (P < 0.05). Patients who presented initially to the tertiary center (T 2 = 0) had a significantly lower resection rate than patients transported from other hospitals (24 vs. 44 %, P = 0.048). There was no significant difference in morbidity between the BR and NBR groups (35 vs. 24 %, P = 0.231). CONCLUSIONS The elapsed time from onset to surgery, especially T 1 and T 2, is the most important prognostic factor in patients with strangulated groin hernias. Early diagnosis and transportation are essential for good outcomes.

Abstract
AIM This preliminary study was performed to test the reliability and validity of the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB), developed by the National Institute of Mental Health MATRICS initiative, as an assessment tool in a Japanese-language version (MCCB-J). METHODS The subjects for the present study were 37 patients with schizophrenia. Each subject gave written informed consent to participate in the research. In order to examine the validity of the MCCB-J, the correlation between the MCCB-J and the Japanese-language version of the Brief Assessment of Cognition in Schizophrenia (BACS) was determined. RESULTS Cronbach's alpha for the MCCB-J was 0.72. The MCCB-J composite score was significantly correlated with all subtests of the MCCB-J. There was a significant correlation between the MCCB-J and the BACS composite score. CONCLUSION This preliminary study indicates that the MCCB-J has good psychometric properties and validity.

Abstract
AIMS The purpose of the present study was to investigate the correlation between cognitive function and clinical variables in people with schizophrenia. METHODS The subjects were 61 stabilized outpatients with schizophrenia (DSM-IV). Their mean age was 40.1 (SD = 12.2) years. All subjects gave written informed consent to participate in the research. Cognitive function was evaluated using the Brief Assessment of Cognition in Schizophrenia. Clinical symptoms were assessed using the Positive and Negative Syndrome Scale, the Calgary Depression Scale for Schizophrenia, and the Drug-Induced Extrapyramidal Symptoms Scale. RESULTS The Positive and Negative Syndrome Scale Negative syndrome score was significantly correlated with verbal memory score (r = -0.37, P < 0.01), working memory score (r = 0.38, P < 0.01), attention and speed of information processing score (r = -0.51, P < 0.01), verbal fluency score (r = -0.39, P < 0.01), and composite score (r = -0.54, P < 0.01). In addition, the Drug-Induced Extrapyramidal Symptoms Scale score was significantly correlated with attention and speed of information processing (r = -0.45, P < 0.01), and composite score (r = -0.41, P < 0. 01). Dose of antipsychotics and anti-Parkinson drugs was not significantly correlated with the Brief Assessment of Cognition in Schizophrenia scores. CONCLUSIONS These results indicate that cognitive dysfunction of people with schizophrenia might be associated with negative and drug-induced extrapyramidal symptoms, suggesting that their minimization would be important for improving cognitive dysfunction.

Effects of tapering of long-term benzodiazepines on cognitive function in patients with schizophrenia receiving a second-generation antipsychotic. Prog Neuropsychopharmacol Biol Psychiatry 2012; 36:300-6.

Abstract
BACKGROUND The high use of long-term benzodiazepines (BZDs) with second-generation antipsychotics (SGAs) has been identified as an important issue in the treatment of schizophrenia in Japan. The aim of this study was to evaluate the effects of gradual reduction or discontinuation of daytime BZD use on cognitive function and quality of life (QOL) in patients with chronic schizophrenia receiving an SGA. METHODS Thirty schizophrenic patients who had received an SGA with concomitant BZDs for at least 3 months were enrolled. Before and 4 weeks after tapering of daytime BZDs, the Brief Assessment of Cognition in Schizophrenia Japanese-language version (BACS-J) and the Schizophrenia Quality of Life Scale Japanese-language version (SQLS-J) were administered. Clinical evaluation also included the Positive and Negative Syndrome Scale (PANSS). To compare for practice effects on the BACS-J, 10 patients with chronic schizophrenia were assessed without tapering BZDs. RESULTS BZDs were reduced or discontinued safely in most patients, and no emergent withdrawal symptoms were observed. Significant improvements were shown in verbal memory, working memory, and composite score, as measured by the BACS-J without practice effects. In addition, the motivation/energy score on the SQLS-J, the negative symptoms and total scores on the PANSS significantly improved after tapering BZDs. CONCLUSION Reduction or discontinuation of long-term daytime use of BZDs may be warranted in patients with schizophrenia treated with SGAs, as it may improve cognitive function, subjective QOL, and psychiatric symptoms with no significant adverse effects.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effects of blonanserin, a novel antipsychotic, on cognitive function in first-episode schizophrenia. METHODS Twenty-four antipsychotic-naïve patients with first-episode schizophrenia participated in the study. Blonanserin was given in an open-label design for 8 weeks. The Brief Assessment of Cognition in Schizophrenia-Japanese language version (BACS-J) was administered as the primary outcome measure at baseline and 8 weeks. Clinical evaluation included the Positive and Negative Syndrome Scale (PANSS), the Schizophrenia Quality of Life Scale-Japanese language version (SQLS-J), and the Clinical Global Impression-Severity of Illness Scale (CGI-S). To exclude the possibility of retest effects on the BACS-J, 10 age-matched patients with chronic schizophrenia treated with blonanserin were tested at baseline and after an 8-week interval. RESULTS Twenty first-episode patients completed the study. Repeated measures analysis of covariance revealed a significant group-by-time interaction effect on the letter fluency task due to better performance in the first-episode group, but not in the control group. Main effect of time or group-by-time interaction effect on the Tower of London task was not significant; however, the first-episode group, but not the control group, showed substantial improvement with a moderate effect size. All items on the PANSS, SQLS-J, and CGI-S significantly improved after 8 weeks of treatment. CONCLUSIONS These results suggest that blonanserin improves some types of cognitive function associated with prefrontal cortical function.

Abstract
The assessment of cognitive function is important for patients with schizophrenia because cognitive impairment is a core feature of the disease, and is a major determinant of functional outcome. To implement a practical assessment tool, we previously developed the Japanese-language version of the Brief Assessment of Cognition in Schizophrenia that objectively measures cognitive domains relevant to outcome. Meanwhile, the U.S. Food and Drug Administration took the position that a drug to improve coghition should show changes on an additional measure (a co-primary), in addition to an accepted consensus cognitive performance measure that is considered functionally meaningful. Thus, four potential co-primary measures, two measures of functional capacity and two interview-based measures of cognition, were evaluated for psychometric properties and validity. The Schizophrenia Cognition Rating Scale (SCoRS) is one of the interview-based measures of cognition. It consists of 20 questions to measure attention, memory, reasoning and problem solving, working memory, language production, and motor skills, which are related to day-to-day functioning. University of California at San Diego Performance-Based Skills Assessment (UPSA) is one of the measures of functional capacity. For its clinical application, we developed the Japanese-language version of the SCoRS (SCoRS-J) and UPSA (UPSA-J) through back-translation into English.

Abstract
We have developed a novel tuberculosis (TB) vaccine; a combination of the DNA vaccines expressing mycobacterial heat shock protein 65 (HSP65) and interleukin 12 (IL-12) delivered by the hemagglutinating virus of Japan (HVJ)-envelope and -liposome (HSP65 + IL-12/HVJ). This vaccine provided remarkable protective efficacy in mouse model compared to the BCG. This vaccine also provided therapeutic efficacy against multi-drug resistant TB (MDR-TB) and extremely drug resistant TB (XDR-TB) in murine models. Furthermore, we extended our studies to a cynomolgus monkey model, which is currently the best animal model of human tuberculosis. This novel vaccine provided a higher level of the protective efficacy than BCG based upon the assessment of mortality. The BCG prime and HSP65 + IL-12/HVJ vaccine (boost) by the prime-boost method showed a synergistic prophylactic effect in the monkey. Furthermore, this vaccine exerted therapeutic efficacy (100% survival) and augmentation of immune responses in the TB-infected monkeys.HVJ-Envelope/HSP65 DNA + IL-12 DNA vaccine increased the body weight of TB-infected monkeys, improved the ESR, and augmented the immuneresponses (proliferation of PBL and IL-2 production). The enhancement of IL-2 production from monkeys treated with this vaccine was correlated with the therapeutic efficacy of the vaccine. These data indicate that our novel DNA vaccine might be useful against Mycobacterium tuberculosis including XDR-TB and MDR-TB for human therapeutic clinical trials.

Abstract
Dacarbazine (DTIC) is one of the most popular alkylating agents used for the treatment of malignant melanoma. DTIC induces apoptosis of melanoma cells via double-strand breaks (DSBs). Melanoma cells, however, tend to increase their expression of DNA repair molecules in order to be resistant to DTIC. Here, we show that DTIC increases expression of Rad51, but not Ku70, in a cultured B16-F10 mouse melanoma cell line in dose- and time-dependent manners. On introducing Rad51 short interfering RNA (siRNA) with the hemagglutinating virus of Japan envelope (HVJ-E) to B16-F10 cells, DSBs induced by DTIC treatment were not efficiently repaired and resulted in enhanced apoptotic cell death. Colony formation of B16-F10 cells that received Rad51 siRNA was significantly decreased by DTIC treatment as compared with cells that received scramble siRNA. In melanoma-bearing mice, the combination of three intratumoral injections of HVJ-E containing Rad51 siRNA and five intraperitoneal injections of DTIC at a clinical dose synergistically suppressed the tumors. Moreover, HVJ-E demonstrated anti-tumor immunity by inducing cytotoxic T lymphocytes to B16-F10 cells on administration of DTIC. These results suggest that the combination of chemotherapy with HVJ-E containing therapeutic molecules will provide a promising therapeutic strategy for patients bearing malignant tumors resistant to chemotherapeutic agents.

Abstract
Background The CogState Schizophrenia Battery (CSB), a computerized cognitive battery, covers all the same cognitive domains as the Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery but is briefer to conduct. The aim of the present study was to evaluate the criterion and construct validity of the Japanese language version of the CSB (CSB-J) in Japanese patients with schizophrenia. Methodology/Principal Findings Forty Japanese patients with schizophrenia and 40 Japanese healthy controls with matching age, gender, and premorbid intelligence quotient were enrolled. The CSB-J and the Brief Assessment of Cognition in Schizophrenia, Japanese-language version (BACS-J) were performed once. The structure of the CSB-J was also evaluated by a factor analysis. Similar to the BACS-J, the CSB-J was sensitive to cognitive impairment in Japanese patients with schizophrenia. Furthermore, there was a significant positive correlation between the CSB-J composite score and the BACS-J composite score. A factor analysis showed a three-factor model consisting of memory, speed, and social cognition factors. Conclusions/Significance This study suggests that the CSB-J is a useful and rapid automatically administered computerized battery for assessing broad cognitive domains in Japanese patients with schizophrenia.

Abstract
The main purpose of the present study was to examine the relationship between quality of life (QOL) and cognitive dysfunction in schizophrenia. Subjects were 61 stabilized outpatients. Quality of life and cognitive function were assessed using the Quality of Life Scale (QLS) and the Brief Assessment of Cognition in Schizophrenia (BACS), respectively. Clinical symptoms were evaluated with the Positive and Negative Syndrome Scale (PANSS) and the Calgary Depression Scale for Schizophrenia (CDSS). The BACS composite score and the BACS Verbal memory score were positively correlated with the QLS total score and two subscales. The BACS Attention and speed of information processing score had positive correlation with the QLS total and all the subscales scores. The PANSS Positive and Negative syndrome scores also had significant correlations with the QLS total score and all of the subscales. In addition, the CDSS score was negatively correlated with the QLS total score and some of the subscales. Stepwise regression analysis showed that the BACS Attention and speed of information processing score was an independent predictor of the QLS total score but it was less associated with the QLS than the PANSS Negative syndrome score and the CDSS score. The results suggest that negative and depressive symptoms are important factors on patients' QOL and also support the view that cognitive performance provides a determinant of QOL in patients with schizophrenia.

Abstract
BACKGROUND The high use of long-term antiparkinsonian anticholinergic drugs with antipsychotics has been identified as an important issue in the treatment of schizophrenia in Japan. The aim of this study was to evaluate the effects of gradual discontinuation of biperiden, an anticholinergic drug, on cognitive function and quality of life (QOL) in schizophrenia. METHODS Thirty-four schizophrenic patients who had received a second-generation antipsychotic (SGA) with concomitant biperiden for at least 3 months were enrolled. Before and 4 weeks after discontinuation of biperiden, the Japanese version of the Brief Assessment of Cognition in Schizophrenia (BACS-J) and the Schizophrenia Quality of Life Scale (SQLS-J) were administered. Clinical evaluation also included the Positive and Negative Syndrome Scale (PANSS). To compare the practice effect on BACS-J, 10 chronic patients with schizophrenia were assessed without tapering biperiden. RESULTS Biperiden was discontinued safely in most patients, and no emergent extrapyramidal symptoms were observed. Significant improvements were shown in attention, processing speed, and composite score, as measured by the BACS-J without practice effect. In addition, the psychosocial condition score on the SQLS-J and the general psychopathology score on the PANSS significantly improved after biperiden discontinuation. CONCLUSION Discontinuation of long-term biperiden use may be warranted in patients with schizophrenia treated with SGAs, as it may improve cognitive function, subjective QOL, and psychiatric symptoms with no significant adverse effects.

Abstract
A numerical analysis is made on the four-point correlation function in a similarity range of a model of two-dimensional passive scalar field ψ advected by a turbulent velocity field with infinitely small correlation time. The model yields an exact closure equation for the four-point correlation Ψ{4} of ψ, which may be casted into the form of an eigenvalue problem in the similarity range. The analysis of the eigenvalue problem gives not only the scale dependence of Ψ{4} , but also the dependence on the configuration of the four points. The numerical analysis gives S4(R)∝R{ζ{4}} in the similarity range in which S2(R)∝R{ζ{2}} , where S_{N} is the structure function defined by S{N}(R)≡⟨[ψ(x+R)-ψ(x)]{N} and ζ{4}≠2ζ{2} . The estimate of ζ_{4} by the numerical analysis of the eigenvalue problem is in good agreement with numerical simulations so far reported. The agreement supports the idea of universality of the exponent ζ{4} in the sense that ζ_{4} is insensitive to conditions of ψ outside the similarity range. The numerical analysis also shows that the correlation C(R,r)≡[ψ(x+R)-ψ(x)]{2}[ψ(x+r)-ψ(x)]{2}> is stronger than that given by the joint-normal approximation, and scales like C(R,r)∝(r/R){χ} for r/R<<1 with R and r in the similarity range, where χ is a constant depending on the angle between R and r .

SUMMARY The main component of the metabolic by-products of fermentation by Propionibacterium freudenreichii ET-3 is 1,4-dihydroxy-2-naphthoic acid (DHNA), which has a naphthoquinone skeleton, as in vitamin K2. This study showed that DHNA improved bone mass reduction with osteoporosis model mice caused by FK506. INTRODUCTION Growth of the intestinal bacterium Lactobacillus bifidus is specifically facilitated by DHNA. The present study used osteoporosis model mice to investigate the effects of DHNA on bone remodeling. METHODS FK506, an immunosuppressant, was used to prepare osteoporosis model mice. Thirty mice were divided into three groups: FK group, FK+DHNA group, and control group. In the FK group, FK506 was administered to induce bone mass reduction. In the FK-DHNA group, FK506 and DHNA were administered concurrently to observe improvements in bone mass reduction. To ascertain systemic and local effects of DHNA, we investigated systemic pathological changes in colon, kidney function and cytokine dynamics, and morphological and organic changes in bone and osteoclast dynamics as assessed by culture experiments. RESULTS Compared to the FK group without DHNA, colon damage and kidney dysfunction were milder for FK+DHNA group, and production of inflammatory cytokines (interleukin (IL)-1beta, IL-6 and tumor necrosis factor (TNF)-alpha) was more suppressed. Furthermore, compared to the group without DHNA, histological analyses and radiography showed that bone resorption was suppressed for the DHNA group. Culture experiments using osteoclasts from murine bone marrow showed osteoclast suppression for the DHNA group compared to the group without DHNA. CONCLUSION These results show that DHNA has some effects for improving bone mass reduction caused by FK506.

Determinants of work outcome in neuroleptic-resistant schizophrenia and schizoaffective disorder: cognitive impairment and clozapine treatment. Psychiatry Res 2010; 178:57-62. [PMID: 20452677 DOI: 10.1016/j.psychres.2009.04.001] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2008] [Revised: 03/29/2009] [Accepted: 04/15/2009] [Indexed: 11/16/2022]
Abstract
There is considerable evidence that cognitive impairment is a better predictor of work and social function in schizophrenia than are positive and negative symptoms. Atypical antipsychotic drugs have been shown to improve cognitive function in schizophrenia patients, but it is unclear whether this improves patients' ability to gain employment. Data from a prospective longitudinal study was used to test the hypotheses that (1) clozapine treatment would improve employment outcome in treatment-resistant schizophrenia or schizoaffective disorder patients, and (2) specific cognitive functioning at baseline and after treatment would predict work status at baseline and change in work status. Employment status and cognitive assessment data were collected in 59 treatment-resistant schizophrenia or schizoaffective disorder patients. Forty-seven of 59 (79.7%) patients were unemployed at baseline. Over a 12-month period, 23 (48.9%) additional patients were able to gain paid or volunteer jobs, or attend school. As predicted, neurocognitive performance was a better predictor of employment status and ability to gain of employment than clinical symptoms. Improvement in verbal working memory was found to be a better predictor of employment outcome than other cognitive functions. Treatment that enhances cognitive function, especially verbal working memory, may lead to better employment outcomes in treatment-resistant schizophrenia or schizoaffective disorder patients.

Abstract
In this naturalistic cross-sectional study, the author tested the hypothesis that verbal working memory (WM) in major depressive disorder (MDD) would predict functional outcome. The subjects consisted of 54 clinic adult out-patients. The author found that, in the patients with current episode of MDD, functional outcome was significantly correlated with depressive scores, but not with Digit Sequencing Task scores. Meanwhile, in a sample of full remitted or partial remitted (mildly depressed) patients, functional outcome was significantly correlated with both Digit Sequencing Task scores and depressive scores. Moreover, in a sample of full remitted or partial remitted (mildly depressed) patients, the Digit Sequencing Task score significantly contributed to the prediction of the functional outcome, but the depressive score did not. The findings in this study suggested that enhancement of verbal WM function may be useful to achieve normalization of functioning as an important component of remission in addition to symptomatic remission.

Abstract
We have developed a novel tuberculosis (TB) vaccine; a combination of the DNA vaccines expressing mycobacterial heat shock protein 65 (HSP65) and interleukin 12 (IL-12) delivered by the hemagglutinating virus of Japan (HVJ)-envelope and -liposome (HSP65 + IL-12/HVJ). An IL-12 expression vector (IL-12DNA) encoding single-chain IL-12 proteins comprised of p40 and p35 subunits were constructed. This vaccine provided remarkable protective efficacy in mouse and guinea pig models compared to the BCG vaccine on the basis of C.F.U of number of TB, survival, an induction of the CD8 positive CTL activity and improvement of the histopathological tuberculosis lesions. This vaccine also provided therapeutic efficacy against multi-drug resistant TB (MDR-TB) and extremely drug resistant TB (XDR-TB) (prolongation of survival time and the decrease in the number of TB in the lung) in murine models. Furthermore, we extended our studies to a cynomolgus monkey model, which is currently the best animal model of human tuberculosis. This novel vaccine provided a higher level of the protective efficacy than BCG based upon the assessment of mortality, the ESR, body weight, chest X-ray findings and immune responses. All monkeys in the control group (saline) died within 8 months, while 50% of monkeys in the HSP65+hIL-12/HVJ group survived more than 14 months post-infection (the termination period of the experiment). Furthermore, the BCG priming and HSP65 + IL-12/HVJ vaccine (booster) by the priming-booster method showed a synergistic effect in the TB-infected cynomolgus monkey (100% survival). In contrast, 33% of monkeys from BCG Tokyo alone group were alive (33% survival). Furthermore, this vaccine exerted therapeutic efficacy (100% survival) and augmentation of immune responses in the TB-infected monkeys. These data indicate that our novel DNA vaccine might be useful against Mycobacterium tuberculosis including XDR-TB and MDR-TB for human therapeutic clinical trials.

Abstract
It is now generally believed that DNA methylation is responsible for genomic imprinting in mammals (1). Recent experimental evidence has provided an elegant mechanism for repression of gene expression by DNA methylation. This evidence suggests that proteins that recognize specifically methylated CpGs may contribute to the formation of inactive chromatin (2-5). Nucleosomes are the basic unit of chromatin, consisting of a core of 146 bp of DNA wrapped around a histone octamer (two molecules of each of H2A, H2B, H3, and H4) and a stretch of linker DNA between adjacent nucleosomes. The binding of a fifth histone, known as a linker histone or H1, promotes the packaging of strings of nucleosomes into a 30 nm chromatin fiber (6). Packaging of DNA into nucleosomes and the chromatin fiber greatly restricts the availability of the DNA for nuclear processes such as transcription.

Ex vivo transfer of nuclear factor-kappaB decoy ameliorates hepatic cold ischemia/reperfusion injury. Transplant Proc 2009; 41:1504-7.

Abstract
Cold ischemia/reperfusion injury of the hepatic graft has been attributed to the release of various inflammatory cytokines. Specific inhibition of these cytokines may improve viability of the hepatic graft upon reperfusion. Herein we have assessed the efficacy of cis element decoy against nuclear factor-kappaB binding site delivery to the hepatic tissue in a rodent liver transplantation model. At 8 hours after reperfusion of the liver, significant reduction was noted in the livers treated with decoy in the release of cytosolic enzymes from the hepatocytes and in serum tumor necrosis factor alpha (P < .05). The neutrophilic infiltration into the hepatic grafts was significantly suppressed in the livers treated with decoy oligodeoxynucleotides (ODNs). Decoy ODNs against nuclear factor-kappaB binding site delivery improved the viability of the hepatic graft against cold ischemia/reperfusion injury in the rodent liver transplantation model.
