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
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.

Measurement and Treatment Research toImprove Cognition in Schizophrenia Consensus Cognitive Battery: validation of the Japanese version. Psychiatry Clin Neurosci 2013; 67:182-8. [PMID: 23581870 DOI: 10.1111/pcn.12029] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2012] [Revised: 01/25/2013] [Accepted: 02/02/2013] [Indexed: 11/27/2022]
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.

[Schizophrenia Cognition Rating Scale Japanese version (SCoRS-J) as a co-primary measure assessing cognitive function in schizophrenia].

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
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
We demonstrated here the growth-suppressing effects of sodium butyrate (NaB) on human endometrial and ovarian cancer cells. The arrest of cells at the G1 checkpoint accounted for this effect. NaB-mediated p21 might arrest endometrial and ovarian cancer cells at the G0/G1 phase by eliciting pRb unphosphorylation. To demonstrate the role of pRb regulation by p21, we measured the sensitivity to NaB of cervical cancer cells in which pRb had been inactivated by HPV E7. The cervical cancer cells displayed a sensitivity in NaB-mediated G2/M arrest in addition to their sensitivity in G0/G1 arrest. Arrest at G0/G1 and G2/M accompanied induction of senescence-like phenotypes (SLPs). Most importantly, the effect of NaB on senescence induction was not coupled with the predominance of hypophosphorylated pRb forms in the cervical cancer cells. This suggested that NaB had the potential to elicit SLPs through p21-mediated withdrawal from cell cycle progression. The consequences of p21 induction were manifold. The effects of NaB on gynecologic cancer cell growth indicated its potential use in cancer treatment. NaB was effective even in the cancer cells with mutant p53 and/or Rb genes by eliciting cell senescence.

Abstract
Quartz crystal resonators, including electric twins, are investigated. Electric twins are artificially formed in the usual AT-cut quartz crystal resonantor before the deposition of electrodes. We have directly observed that vibrations generated at electrodes propagate into the outside region isotropically, but cannot propagate into the region of electric twin.

Abstract
Hepatocyte growth factor (HGF) is a multifunctional growth factor which has pleiotrophic biological effects on epithelial cells such as proliferation, motogenesis, invasiveness and morphogenesis. Peritoneal dissemination is critical for the progression of ovarian cancer, and our study revealed that HGF induces migration and invasion of ovarian cancer cells. We also demonstrated that HGF stimulates autophosphorylation of its receptor, followed by activation of the Ras-MAP (mitogen-activated peptide) kinase cascade. Moreover, infection of ovarian cancer cells with Ras dominant-negative adenovirus reduced the HGF-induced motogenic and invasive activities. Additionally, both MEK and P13-kinase pathways downstream of Ras were involved in HGF-stimulated ovarian cancer cell invasiveness.

Abstract
Estrogen has an important role in both the etiology and treatment of hormone-dependent endometrial cancers, although the mechanism remains elusive. To definethe role of estrogen-mediated signaling we investigated the biological significance of estrogen receptors (ER) in NIH3T3 cell transformation via the [ ¹2; Val ] K-Ras mutant. This mutant enhanced the steady state level and transcriptional activity of ER. In addition, overexpression of both wild type K-Ras and ER transformed NIH3T3 cells. Co-expression of the progesterone receptor (PR) with mutant K-Ras led to suppression of tumorigenicity and inhibition of ER activation. The antisense oligomers complementary to ER suppressed proliferation and transformed phenotypes of K12V cells. These observations support the importance of ER in Ras-mediated cell transformation. To address whether ER activation is also important in the development of human endometrial cancers, we investigated ER and PR expression levels in premalignant and malignant endometrial lesions. The results suggested the implication of ER abundance in endometrial hyperplasias, though modulation of PR expression by ER was retained. G1 adenocarcinoma also expressed higher levels of ER while PR modulation by ER was abrogated. These data implied the importance of ER activitiesin endometrial hyperplasia and G1 adenocarcinoma development.

Abstract
The WAF1 protein, which is a downstream mediator of p53, functions as a universal inhibitor of cyclin-dependent kinases. The functional link between p53 and WAF1 suggests the possibility that alteration in WAF1 function constitutes an alternative mechanism to p53 inactivation. However, there are few reports describing somatic mutations of the WAF1 gene in various human malignancies. A polymorphism in the WAF1 gene, a C-to-A transversion at codon 31 resulting in the change of a serine (Ser) to an arginine (Arg), is well known. We found this substitution in 42 of 54 endometrial carcinoma patients. Allele frequency was 0.44/0.56 for the codon 31 polymorphism (Ser/Arg), the difference of allele frequency between patients and normal controls being significant (0.59/0.41 in normal controls). In addition, individuals carrying the codon 31 Arg allele had a tendency to develop histologically high-grade (odds ratio, 6. 11) and clinically advanced tumors. We investigated the association of the Arg allele with the known risk factors of endometrial carcinomas. Statistical analyses of 42 cases and 32 controls carrying the codon 31 Arg allele identified hypertension (odds ratio, 4.33) and family history of cancer (odds ratio, 2.81) as positive risk factors. This implies that these two parameters may be associated with a tendency to develop endometrial carcinomas in individuals carrying the codon 31 Arg allele of the WAF1 gene.

Abstract
Since the majority of endometrial carcinomas do not contain any detectable ras mutations, the precise contribution of aberrant Ras function, if any, to endometrial carcinoma development remains to be determined. Since there is considerable evidence that Ras transformation is associated with a decreased requirement for growth factors, we compared the growth response of endometrial carcinoma cells harbouring wild-type (Ishikawa cells) or mutated (HHUA cells) K-ras to epidermal growth factor (EGF). K-ras mutation did not significantly affect the level of the EGF receptor (EGFR) expressed in these carcinoma cells. EGF could stimulate the growth of Ishikawa, but not HHUA cells. Furthermore, EGF caused elevation of Ras-GTP levels in Ishikawa, but not HHUA cells. However, the introduction of mutated, but not normal, K-ras into Ishikawa cells rendered them non-responsive to EGF growth stimulation. Thus, the presence of mutated K-ras alone modulated the growth response of endometrial carcinoma cells to EGF. An inhibitor of the EGFR tyrosine kinase activity could prevent soft agar colony formation of Ishikawa cells, but not HHUA or mutant K-ras(12V)-transfected Ishikawa cells. Taken together, these results suggest that mutated K-ras causes a loss of responsiveness to EGF stimulation and that EGFR function is dispensable for the growth of mutant Ras-positive endometrial carcinoma cells.

Abstract
To investigate regulation mechanisms of G2/M phase transition, we studied the association of cell cycle progression with p53-dependent p21/waf-1 and cyclinG expression. We used doxorubicin (DOX) and sodium butyrate (NaB) to accumulate p53 protein. DOX treatment resulted in an apparent increase of cells in the G2/M fraction, whereas NaB arrested cells at G1. P53 protein induction in response to DOX accompanied up-regulation of p21/waf-1 and cyclinG expression. However, cyclinG was undetectable in NaB-treated cells. These results implied a putative association between increases in the proportion of cells accumulating in the G2/M fraction and enhanced cyclinG expression. Antisense oligo DNAs (AS) complementary to cyclinG mRNA inhibited the cyclinG protein expression induced by DOX treatment. This inhibition resulted in a marked reduction in the number of cells arrested at G2/M and accumulating at G1. A role for cyclinG in G2/M phase transition control is implied.

Abstract
We investigated the biological significance of estrogen receptors (ER) in NIH3T3 cell transformation by the [12Val] K-Ras mutant. This mutant enhanced the steady state level of ER. Cells expressing mutant K-Ras (K12V cell) were tumorigenic. To determine the role of ER accumulation in Ras-transformed cells, we developed cells (KwtER cells) that overexpressed both wild-type (wt) K-Ras and ER, and found these cells were also tumorigenic. E2 stimulated the transcriptional activity by ER dominantly in K12V cells. However, only partial activation of ER by E2 was seen in KwtER cells. In the presence of 10% serum in media, the activation of ER appeared only in transformed KtwER and K12V cells, suggesting that two independently transmitted signals, the E2-ER binding and the ER-AF1 activation, are necessary for ER activation and that the dominant activation of ER might be involved in Ras-mediated cell transformation. Co-expression of progesterone receptor (PR) with mutant K-Ras led to suppression of tumorigenicity and inhibition of the activation of ER. The antisense oligomers complementary to the ER suppressed proliferation and transformed phenotypes of K12V cells. These observations support the importance of ER in Ras-mediated cell transformation.

Abstract
We report the first familial case of dominantly inherited aniridia with a cryptic inversion within band 11p13. High-resolution chromosome analysis gave a suspicion of a tiny constitutional aberration around band 11p13 and fluorescence in situ hybridization using 11p cosmids successfully confirmed that the aniridia patients of this family have an inversion within band 11p13. The distal breakpoint of the inversion is telomeric to a candidate aniridia gene (AN2) and suggests that more genes might be involved in the etiology of aniridia. In situ hybridization is a powerful tool to detect cryptic rearrangements in sporadic or familial patients with aniridia. This family indicated the importance of careful observation of the 11p13 region of aniridia patients, even if the aniridia was autosomal dominantly inherited.

Possible assignment of this autosomal dominant disorder is discussed. A 3q23 band is a more preferable gene locus of the belpharophimosis sequence, based on the comparison of clinical manifestations between 4p- and 3q-syndromes.

A 7-year-old girl with cytochrome c oxidase deficiency who had no neurologic deficits in infancy suddenly developed ophthalmoplegia, ptosis, and respiratory arrest. She recovered almost completely 80 days after onset, suggesting that acute onset and rapid remission are observed in patients with cytochrome c oxidase deficiency. It is also possible that early initiation of therapy in cytochrome c oxidase deficiency with coenzyme Q10 may hasten and enhance the therapeutic effect.

Abstract
In 7 cases with unilateral cerebellar vascular lesion, decreased perfusion was observed in the contralateral cerebral cortex by single photon emission computed tomography (SPECT) with I-123 labeled N-isopropyl-p-iodoamphetamine (IMP). These cases had symptoms due to cerebellar lesions but did not show any cerebral cortical symptoms. Reduction of cerebral cortical perfusion appeared on more than 25 days after the onset of CVA, did not correlate with morphological changes by cranial X-ray computed tomography and digital subtraction angiography in acute phase, and was persistent or irreversible later. We made a guess this phenomenon was due to the remote neuronal effect through cerebellothalamic projection.

Abstract
A 2-year-old boy underwent bone marrow transplantation for severe aplastic anemia. Eighteen months later he developed chronic lung disease and dryness of the eyes. Ophthalmologic examination revealed obstruction of the nasolacrimal ducts and marked dilatation of the lacrimal sacs bilaterally. It seems likely that the nasolacrimal duct obstruction was a manifestation of chronic graft-versus-host disease.
