Bismuth(III) bromide-thioamide complexes: synthesis, characterization and cytotoxic properties

New bismuth(III) bromine compounds of the heterocyclic thioamides were prepared and structurally characterized. The reaction of heterocyclic thioamides with bismuth(III) bromide resulted in the formation of the {[BiBr2(mu(2)-Br)(MMI)(2)](2)center dot CH3COCH3 center dot H2O} (1), {[BiBr2(MBZIM)(4)]center dot Br center dot 2H(2)O} (2), {[BiBr2(mu(2)-Br)(tHPMT)(2)](2)center dot CH3CN} (3), {[BiBr2(mu(2)-Br)(PYT)(2)](2)center dot CH3CN} (4) and {[BiBr2(mu(2)-Br)(MBZT)(2)](2) 2CH(3)OH} (5) complexes (MMI: 2-mercapto-1-methylimidazole, MBZIM: 2-mercaptobenzimidazole, tHPMT: 2-mercapto-3,4,5,6-tetrahydro-pyrimidine, PYT: 2-mercaptopyridine and MBZT: 2-mercaptobenzothiazole). The complexes 1-5 were characterized by melting point (m.p.), elemental analysis (c.a.), molar conductivity, Fourier-transform infrared (FT-IR), Fourier-transform Raman (FT-Raman), nuclear magnetic resonance (H-1 and (CNMR)-C-13) spectroscopy, UV-Vis spectroscopy and thermogravimetric-differential thermal analysis (TG-DTA). The molecular structures of 1-5 were determined by single-crystal X-ray diffraction. Complex 2 is a first ionic monomuclear octahedral bismuth(III) bromide, while the complexes 1,3-5 are the first examples of dinuclear bismuth(III) bromide derivatives. Complexes 1-5 were evaluated in terms of their in vitro cytotoxic activity against human adenocarcinoma breast (MCF-7) and cervix (HeLa) cells. The toxicity on normal human fetal lung fibroblast cells (MRC-5) was also evaluated. Moreover, the complexes 1-5 and free heterocyclic thioamide ligands were studied upon the catalytic peroxidation of the linoleic acid by the enzyme lipoxygenase (LOX).Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [114Z457](a) I.I.O. and M.C. acknowledge the financial support from The Scientific and Technological Research Council of Turkey (TUBITAK, Project No. 114Z457).

Internal consistency and discriminant validity of the Structured Clinical Interview for Panic Agoraphobic Spectrum (SCI-PAS)

This paper reports on the feasibility, acceptability and psychometric properties of the Structured Clinical Interview for Panic-Agoraphobic Spectrum (SCI-PAS). This interview was designed to assess the lifetime presence of symptoms and other clinical features considered to comprise the panic-agoraphobic spectrum. The interview has 114 items grouped into nine domains. A total of 422 subjects, from 11 centres located throughout Italy, participated in this study. Data were collected from three groups of subjects: psychiatric patients meeting DSM-IV criteria for panic disorder (n = 141), cardiovascular patients (n = 140), including 29 with post-myocardial infarction, and university students (n = 141). The inter-rater reliability and the internal consistency of the SCI-PAS measures were assessed using the intra-class correlation coefficient and the Kuder-Richardson coefficient, respectively. Discriminant validity was assessed by comparing results in patients with panic disorder to those in the other groups. The interview required an average of 25 (±5) minutes to administer. Patients and clinicians found the scale to be highly useful, providing information not previously obtained. Internal consistency was good (>0.70) for six out of nine SCI-PAS domains. The inter-rater reliability was excellent (>0.70) for all the domains except for 'other phobias' (0.467). Patients with panic disorder scored significantly higher on each domain, and on the overall panic spectrum, than did the control subjects. In conclusion, the SCI-PAS is a useful clinical interview, which can be administered in a reasonable period of time. This assessment further demonstrates good internal consistency, discriminant validity, and inter-rater reliability. Copyright © 1999 Whurr Publishers Ltd

Maternal-foetal attachment independently predicts the quality of maternal-infant bonding and post-partum psychopathology

Purpose: The aim of this study was to evaluate the association of maternal antenatal attachment and post-partum psychopathology, maternal–infant bonding, while checking for antenatal psychopathology, for lifetime psychiatric diagnosis and for the known risk factors for peripartum depression. Methods: One hundred and six women recruited at the first month of pregnancy (T0) were evaluated with the structured interview for DSM-IV TR (SCID-I) to assess the presence of lifetime psychiatric diagnosis and with the Perinatal Depression Predictor Inventory-Revised (PDPI-R), the Edinburgh Postnatal Depression Scale (EPDS), and the State–Trait Anxiety Inventory (STAI). At the sixth month of pregnancy (T1) and at the first month post-partum (T2), all patients were evaluated with the PDPI-R, the EPDS, the STAI, at T1, with the Maternal Antenatal Attachment Scale (MAAS), and at T2 with the Maternal Postnatal Attachment Scale (MPAS). Results: Multivariate regression analyses showed that maternal–foetal attachment was the variable most significantly associated with postnatal symptoms of depression and anxiety and with quality of maternal-infant attachment. The logistic regression analyses showed that antenatal attachment may predict postnatal depressive and anxiety symptoms (respectively, OR: 0.83–IC [0.74 − 0.95], p =.005, OR: 0.88–IC [0.79 − 0.98], p =.02), and the quality of maternal postnatal attachment (OR: 1.17–IC [1.08 − 1.27], p <.001), also after taking into account the known risk factors for perinatal depression, the sociodemographic variables and lifetime psychiatric diagnosis. Conclusion: The quality of maternal–foetal bonding may independently predict the quality of maternal–infant attachment and post-partum depressive and anxiety symptoms. A comprehensive assessment of maternal risk factors for perinatal psychopathology during pregnancy should include the evaluation of antenatal attachment that could be modifiable by specific interventions promoting the quality of maternal bonding

Identification of histone deacetylase inhibitors with (arylidene)aminoxy scaffold active in uveal melanoma cell lines

Uveal melanoma (UM) represents an aggressive type of cancer and currently, there is no effective treatment for this metastatic disease. In the last years, histone deacetylase inhibitors (HDACIs) have been studied as a possible therapeutic treatment for UM, alone or in association with other chemotherapeutic agents. Here we synthesised a series of new HDACIs based on the SAHA scaffold bearing an (arylidene)aminoxy moiety. Their HDAC inhibitory activity was evaluated on isolated human HDAC1, 3, 6, and 8 by fluorometric assay and their binding mode in the catalytic site of HDACs was studied by molecular docking. The most promising hit was the quinoline derivative VS13, a nanomolar inhibitor of HDAC6, which exhibited a good antiproliferative effect on UM cell lines at micromolar concentration and a capability to modify the mRNA levels of HDAC target genes similar to that of SAHA

Women's Preferences for Treatment of Perinatal Depression and Anxiety : A Discrete Choice Experiment

Perinatal depression and anxiety (PNDA) are an international healthcare priority, associated with significant short- and long-term problems for women, their children and families. Effective treatment is available but uptake is suboptimal: some women go untreated whilst others choose treatments without strong evidence of efficacy. Better understanding of women's preferences for treatment is needed to facilitate uptake of effective treatment. To address this issue, a discrete choice experiment (DCE) was administered to 217 pregnant or postnatal women in Australia, who were recruited through an online research company and had similar sociodemographic characteristics to Australian data for perinatal women. The DCE investigated preferences regarding cost, treatment type, availability of childcare, modality and efficacy. Data were analysed using logit-based models accounting for preference and scale heterogeneity. Predicted probability analysis was used to explore relative attribute importance and policy change scenarios, including how these differed by women's sociodemographic characteristics. Cost and treatment type had the greatest impact on choice, such that a policy of subsidising effective treatments was predicted to double their uptake compared with the base case. There were differences in predicted uptake associated with certain sociodemographic characteristics: for example, women with higher educational attainment were more likely to choose effective treatment. The findings suggest policy directions for decision makers whose goal is to reduce the burden of PNDA on women, their children and families

La quarta rivoluzione industriale tra opportunità e diseguaglianze

I mutamenti attivati dal progresso e dalla pervasività delle tecnologie sono talmente dirompenti e rapidi che è stata ipotizzata e in diversi ambiti ormai codificata l’esistenza di una quarta rivoluzione industriale. Sembra dunque emergere una nuova rivoluzione in riferimento alla definizione di tecnologie sempre più avanzate (i big data, gli algoritmi, le piattaforme digitali, i sensori, ecc.) capaci di dialogare in maniera efficace tra di loro, ma soprattutto per le implicazioni e le discontinuità, generate sul piano economico, sociale, culturale, spazio-temporale. Avvalendosi di risultati di ricerche originali e aggiornate, il testo si concentra sull’analisi dei cambiamenti innescati e percepiti, ponendo l’accento sia sulle potenzialità di impatto che sulle criticità e sulle disuguaglianze sociali e territoriali. Valorizzando l’apporto di alcune discipline umanistiche e sociali, il libro introduce prospettive di ricerca interdisciplinari ed esplora nuove metodologie di analisi che combinano la dimensione evolutiva (tipica della storia politica e della storia economica) con quella territoriale (prevalente nella geografia) e quella narrativa (particolarmente evidente nella storia e geografia culturale e nelle discipline legate all’immagine, alla rappresentazione, al cinema). L’obiettivo è quello di contribuire al dibattito attuale sulla quarta rivoluzione industriale, evidenziando il contesto storico- politico ed economico in cui si è affermata, i cambiamenti prodotti sul piano sociale, spaziale e mediatico, le percezioni delle trasformazioni e le narrazioni emergenti in ambito culturale e nel mondo del web
