Abstract
Maspin, a class II tumor suppressor, is often downregulated during tumor progression and its depletion from the nucleus is associated with poor prognosis. Recently, we reported that reintroduction of maspin is sufficient for redifferentiation of prostate cancer cells to epithelial phenotype, a reversal of epithelial-to-mesenchymal transition. We have linked this effect of maspin with its ability to directly inhibit HDAC1, thereby influencing the acetylation state of transcription factors and other proteins. Maspin overexpression leads to changes in the expression level of a large number of proteins and these changes are often microenvironment specific. In this review, we summarize the epigenetic effects of maspin and provide comprehensive bioinformatic analysis of microarray-derived gene expression changes caused by maspin in different microenvironments. The analysis was performed on multiple levels, including identification of statistically enriched gene ontology groups, detection of overreprepresented transcription factors binding sites in promoters of differentially expressed genes, followed by searching for key nodes of regulatory networks controlling these transcription factors. The results are consistent with our hypothesis that maspin serves as an endogenous regulator of HDAC activity and suggest that the effect of maspin is primarily mediated by TGFβ, β-catenin/E-cadherin pathways, and network key nodes such as Abl kinase, p62, IL1, and caspases 6 and 8.

Abstract
BACKGROUND Adolescents with early-onset schizophrenia (EOS) have marked deficits in their functional outcome. However, few short and reliable instruments for assessing real-world functioning have been specifically validated in EOS. The Life Skills Profile (LSP) is a brief scale widely used in schizophrenia and considered one of the optimal instruments for assessing real-world daily living skills. The purpose of this study was to examine the usefulness and the feasibility of the LSP to assess daily living skills in EOS. METHODS The sample included 53 clinically and pharmacologically stabilized adolescent patients with EOS and 53 healthy adolescents. Content review of the scale and internal consistency analysis were conducted in the EOS group. A subgroup of 30 patients was re-assessed over a 10-day interval to establish the test-retest reliability. Measures of functional outcome were used to assess convergent validity, and measures of intelligence and symptoms were used to assess divergent validity. Discriminant validity was analyzed through logistic analysis and the receiver-operating characteristic curve. RESULTS The LSP and its subscales showed high reliability, adequate internal consistency and adequate convergent and divergent validity. The LSP was also found to be a sensitive instrument for detecting differences between patients and healthy adolescents, correctly classifying 84% of the sample. The estimated area under the curve was 0.925 (95% CI 0.875-0.976). CONCLUSIONS The LSP showed adequate psychometric characteristics in adolescents with EOS and appeared to be a valid, reliable and time-efficient instrument for use in clinical practice and research settings to assess real-world daily-living skills in EOS.

Abstract
The present work aims to perform a multistep upgrading of chars obtained in the co-pyrolysis of PE, PP and PS plastic wastes, pine biomass and used tires. The quality of the upgraded chars was evaluated by measuring some of their physico-chemical properties in order to assess their valorisation as adsorbents' precursors. The crude chars were submitted to a sequential solvent extraction with organic solvents of increasing polarity (hexane, mixture 1:1 v/v hexane:acetone and acetone) followed by an acidic demineralization procedure with 1M HCl solution. The results obtained showed that the upgrading treatment allow the recovery of 63-81% of the pyrolysis oils trapped in the crude chars and a reduction in the char's ash content in the range of 64-86%. The textural and adsorption properties of the upgraded chars were evaluated and the results indicate that the chars are mainly mesoporous and macroporous materials, with adsorption capacities in the range of 3.59-22.2 mg/g for the methylene blue dye. The upgrading treatment allowed to obtain carbonaceous materials with quality to be reused as adsorbents or as precursors for activated carbon.

Abstract
The present work is devoted to the study of the decontamination of chars obtained in the co-pyrolysis of plastics, biomass and tyre wastes. The chars were extracted with several organic solvents of different polarities either individually or in sequence. The ability of each selected extractant to remove toxic pollutants was evaluated by comparing the extraction yields and by characterizing the crude extracts with a combination of chemical analysis and toxicity bioassays. Also, the mineral composition of the treated and non-treated chars was assessed. The results obtained in this study indicate that hexane is the more efficient extraction solvent to be used in the organic decontamination of chars obtained in the co-pyrolysis of plastics, tyres and biomass. A sequential extraction with solvents of increasing polarity can provide a better decontamination of the raw pyrolysis char than any individual extraction. The compounds removed from the char during the decontamination process are mainly aliphatic hydrocarbons and aromatic hydrocarbons, therefore a material that may be upgraded to be used as a fuel and/or as raw material for the organic chemical industry.

Abstract
Neurocognitive impairment is a core feature of schizophrenia and is closely associated with functional outcome. The importance of cognitive assessment is broadly accepted today, and an easy-to-use, internationality validated cognitive assessment tool is needed by researchers and in daily clinical practice. The Brief Assessment of Cognition in Schizophrenia (BACS) has been validated in English, French, Japanese and Italian. It is as sensitive to cognitive dysfunction as a standard test battery, with the advantage of requiring less than 35minutes to complete. In our study, we tested the psychometric characteristics of a Spanish version of the BACS in 117 patients with schizophrenia-spectrum disorders and 36 healthy controls. All BACS cognitive subtests discriminated between patients and controls (P<.001), and the concurrent validity between the BACS and a traditional neuropsychological test battery was similar to that reported in other languages. We conclude that the BACS can facilitate the comparison of the cognitive performance of patients with schizophrenia in many different countries.

Abstract
The aim of this study is to evaluate whether the quantitative prescription of risperidone (dosage) is related to the patient's metabolic status. Metabolic status was defined in terms of the most relevant polymorphisms of CYP2D6 (*3, *4, *5, *6 and *1xN), CYP3A5 (*3A) and ABCB1 (G2677T) determined a posteriori and blinded to the clinicians. This prospective and observational study includes a cohort of 151 Caucasian psychiatric patients treated with risperidone. Significant differences (Kruskal-Wallis test p=0.01) among the doses administered were observed to correlate (Spearman's r=1, p=0.02) with the different CYP2D6 groups. Poor metabolizers received the lowest doses and ultra rapid metabolizers the highest. No significant correlations were observed with regard to CYP3A5 and ABCB1. We find that, despite not knowing patients' metabolic status, clinicians modify risperidone dosage in order to obtain the best therapeutic option.

Abstract
In this report we directly compare the in vivo and in vitro MRI properties of gadolinium-dendrimer conjugates of derivatized acyclic diethylenetriamine-N,N',N',N'',N''-pentaacetic acid (1B4M-DTPA) and macrocyclic 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (C-DOTA). The metal-ligand chelates were pre-formed in alcohol prior to conjugation to the generation 4 PAMAM dendrimer (G4D), and the dendrimer-based agents were purified by Sephadex(R) G-25 column. The analysis and SE-HPLC data indicated chelate to dendrimer ratios of 30:1 and 28:1, respectively. Molar relaxivity measured at pH 7.4, 22 degrees C, and 3T are comparable (29.5 vs 26.9 mM(-1)s(-1)), and both conjugates are equally viable as MRI contrast agents based on the images obtained. The macrocyclic agent however exhibits a faster rate of clearance in vivo (t(1/2)=16 vs 29 min). Our conclusion is that the macrocyclic-based agent is the more suitable agent for in vivo use for these reasons combined with kinetic inertness associated with the Gd(III) DOTA complex stability properties.

Abstract
Dispersive liquid-liquid microextraction (DLLME) coupled with gas chromatography-mass spectrometry (GC-MS) was applied for the determination of 11 alkylphenols in eluates of chars produced in the co-pyrolysis of different wastes. The optimized DLLME procedure, 4 mL of sample solution, 15 microL of trichloroethylene as extraction solvent, 1 mL of acetone as dispersion solvent and addition of 15% (w/v) of NaCl, was validated. Under the optimum conditions, the enrichment factors were in the range of 82-180. Calibration curves were constructed for each analyte in pure water in the concentration range of 0.5-8 microg/L with correlation coefficients higher than 0.999. The limits of detection were between 0.07 and 0.17 microg/L. The repeatability of the method was evaluated using water samples fortified with the analyte mixture at two concentration levels: the relative standard deviation (RSD) values were between 3.7% and 8.0% for a concentration of 0.5 microg/L, and between 4.2% and 6.4% for a concentration of 3 microg/L. The recoveries of the analytes evaluated by fortification of real eluate samples were in the range of 67.9-97.9% for eluate 1 (obtained from a decontaminated char) and in the range of 61.9-101.4% for eluate 2 (obtained from the untreated char). o-Methylphenol presented low recoveries for both eluates showing a possible matrix effect. The results obtained show that this method is adequate for the determination of alkylphenols in environmental aqueous samples and presents itself as a fast and inexpensive technique, using minor amounts of organic solvents.

Abstract
Multi-modality imaging probes combine the advantages of individual imaging techniques to yield highly detailed anatomic and molecular information in living organisms. Herein, we report the synthesis and characterization of a dual-modality nanoprobe that couples the magnetic properties of ultrasmall superparamagnetic iron oxide nanoparticles (USPIOs) with the near infrared fluorescence of Cy5.5. The fluorophore is encapsulated in a biocompatible shell of silica surrounding the iron oxide core for a final diameter of approximately 17 nm. This silica-coated iron oxide nanoparticle (SCION) has been analyzed by transmission electron microscopy, dynamic light scattering, and superconducting quantum interference device (SQUID). The particle demonstrates a strong negative surface charge and maintains colloidal stability in the physiological pH range. Magnetic hysteresis analysis confirms superparamagnetic properties that could be manipulated for thermotherapy. The viability of primary human monocytes, T cells, and B cells incubated with the particle has been examined in vitro. In vivo analysis of agent leakage into subcutaneous A431 tumors in mice was also conducted. This particle has been designed for diagnostic application with magnetic resonance and fluorescence imaging, and has future potential to serve as a heat-sensitive targeted drug delivery platform.

Abstract
Aims:The metabolic syndrome MS (visceral obesity, dyslipidaemia, hyperglycaemia, and hypertension), has become one of the major public-health challenges worldwide. Patients with schizophrenia are more likely to suffer from MS that the general population. We have analyzed the prevalence of MS in Spanish patients with schizophrenia and overweight.Methods:The CRESSOB study is a 12-month, prospective, naturalistic study including 110 community mental health clinics selected at random. Each site enrolled four consecutive patients with diagnosis of schizophrenia, according to DSM-IV TR criteria, and overweight (BMI > 25 Kg/m2). to assess the prevalence of MS we have analyzed the baseline results of the CRESSOB study. the National Cholesterol Educational Program (NCEP-ATPIII), the International Diabetes Federation (IDF) and the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) definitions were used to established the presence of MS.Results:A total of 391 patients were enrolled on the study (mean age 40.5 years, 63.8% men). 75.9% of the patients did not meet criteria for remission, using the selected PANSS items. Mean GAF score was 52.7 (SD 15.4). Using the different criteria, 59.0% of males and 58.3% of females fulfilled the NCEP-ATPIII criteria, 71.1% of males and 65.8% of females fulfilled the IDF criteria and 70.1% of males and 65.1% of females fulfilled the AHA/NHLBI criteria.Conclusions:The MS is highly prevalent in Spanish patients with schizophrenia and overweight. Given the metabolic syndrome is an important risk factor for cardiovascular disease, these patients should receive appropriate clinical monitoring for this syndrome.

Abstract
Mercury emitted from dental amalgam may select for increased numbers of antibiotic- or mercury-resistant commensal bacteria in patients and increase their risk for bacterial diseases that are resistant to common therapies. We hypothesized that the presence of dental amalgams would increase the level of mercury-, tetracycline-, ampicillin-, erythromycin-, or chloramphenicol-resistant oral and urinary bacteria as compared with levels in children receiving composite fillings. Samples were collected at baseline, 3–6 months after the initial dental treatment, and annually for 7 years of follow-up. There were no statistically significant differences between treatment groups in the numbers of bacteria growing on antibiotic- or mercury-supplemented plates. This study provided no evidence that amalgam fillings on posterior teeth influenced the level of antibiotic- or mercury-resistant oral or urinary bacteria as detected by culture.

Abstract
1. The aim of the present study was to perform a descriptive study of the prevalence of the four major CYP2D6 poor metaboliser (PM) alleles (*3, *4, *5 and *6) in a Spanish population (n = 290) using a method based on a new combination of multiplex long polymerase chain reaction (PCR) and minisequencing through multiplex single base extension (SBE) analysis. 2. The method was validated using different strategies, such as allelic discrimination assay and PCR-restriction fragment length polymorphism (RFLP). 3. The allele frequencies were similar to those described for other Spanish populations, namely 0.9% (95% confidence interval (CI) 0.5-1.3), 16.4% (95% CI 14.9-18.0), 2.7% (95% CI 2.0-3.4) and 0.7% (95% CI 0.3-1.0) for the *3, *4, *5 and *6 alleles, respectively. The results were satisfactory and left little doubt as to the genotypes, which were confirmed either by allelic discrimination assay (*4 and *6) or PCR-RFLP (*3) with 100% concordance. 4. The present study corroborates the low prevalence of the most frequent polymorphism (CYP2D6*4) that leads to null CYP2D6 activity in Spain and the allelic geographical gradient between Caucasian populations in the north and south. The present study reports a technique for the detection of four polymorphisms that account for 98% of the CYP2D6 defect alleles. This multiplex long PCR-SBE technique is a combination of several known methods to genotype CYP2D6 alleles (*3, *4, *5 and*6). Given the importance of CYP2D6 in drug metabolism and the need to genotype a large number of samples, we believe that this method will find broad application.

Abstract
OBJECTIVE Estimate the cost-effectiveness of the prevention of relapse of schizophrenia in the ZEUS (Ziprasidone Extended Use in Schizophrenia Study) longitudinal study that compares ziprasidone with the option of not treating. METHODS One year of treatment was analyzed using the randomized clinical trial data (ZEUS study) with a deterministic model, having cost-effectiveness analysis type, conducted from the perspective of the National Health Care System (NHCS). RESULTS Additional mean yearly cost for worsening avoided with ziprasidone was 186 Pounds for the mean dose, ranging from -556 Pounds (savings) with the 80 mg/day dose and 1,014 Pounds with 160 mg/day, which was always lower than the minimum cost of a relapse (2,830 Pounds), considered as threshold value to establish cost-effectiveness of treatment with ziprasidone. CONCLUSIONS Prevention of relapse of schizophrenia with long-term ziprasidone is cost-effective in comparison with the option of not treating. Treatment with ziprasidone avoids relapse episodes at a reasonable cost, generating savings for the NHCS.

Abstract
Since its introduction, electroconvulsive therapy is a treatment used in mood disorders, especially in the depressive phases of bipolar disorder. The advance of this technique has made it a useful and current option both in the treatment of acute phases as in the prevention of recurrences. The objective of this revision is to collect available data about the use of electroconvulsive therapy in bipolar depression. Its indications, effectiveness, prediction and patterns of response are included in this work, together with its complications, adverse events and drug interactions. Differences in response between bipolar and unipolar depression are also discussed.

Abstract
Schizophrenia is characterized by cognitive, social, and emotional impairments and by psychotic symptoms. Neuroimaging studies have reported abnormalities within the prefrontal cortex and it has been hypothesized that schizophrenia results from poor or miswired anatomical/functional connections. We have compared the functional connectivity within the frontal cortex in control and schizophrenic subjects during the realization of a Continuous Performance Task. The connectivity pattern within the frontal cortex was uncovered by the analysis of the correlation matrix computed from the fMRI time series in frontal areas for 14 schizophrenic patients and 14 control subjects. In control subjects, the right dorsolateral prefrontal cortex (DLFCr) activity correlated i) positively with the left dorsolateral prefrontal cortex and the posterior part of the supplementary motor area, ii) negatively with the medial and anterior/inferior part of the frontal cortex. In the schizophrenic group, these relations were abolished or strongly lowered. The negative relation between the DLFCr and the medial frontal cortex has been proposed to play a key role in setting a harmonious balance between the direction of attention to the external world and the expression of the individual believes and self-referential activities, and therefore, the impaired relation of right DLFCr with other frontal areas could explain a distorted perception of external world in relation with internal motivations.
