Differential expression of HINT1 in schizophrenia brain tissue

Recent findings in the literature suggest a relation between histidine triad nucleotide-binding protein-1 (HINT1) and psychiatric disorders such as major depression, anxiety, and schizophrenia, although its physiological roles are not completely comprehended. Using Western blot, we compared HINT1 protein expression in the postmortem dorsolateral prefrontal cortex and thalamus of schizophrenia patients and healthy controls for contributing to elucidate the role of HINT1 in schizophrenia pathophysiology. HINT1 was found to be downregulated in the dorsolateral prefrontal cortex and upregulated in the thalamus. Our results combined to previous studies in human samples and preclinical models support the notion that HINT1 must be more explored as a potential target for psychiatric disorders.

Cross-national differences in questionnaires do not necessarily reflect comparable differences in disorder prevalence

To examine whether the widely used Strengths and Difficulties Questionnaire (SDQ) can validly be used to compare the prevalence of child mental health problems cross nationally. We used data on 29,225 5- to 16-year olds in eight population-based studies from seven countries: Bangladesh, Brazil, Britain, India, Norway, Russia and Yemen. Parents completed the SDQ in all eight studies, teachers in seven studies and youth in five studies. We used these SDQ data to calculate three different sorts of "caseness indicators" based on (1) SDQ symptoms, (2) SDQ symptoms plus impact and (3) an overall respondent judgement of 'definite' or 'severe' difficulties. Respondents also completed structured diagnostic interviews including extensive open-ended questions (the Development and Well-Being Assessment, DAWBA). Diagnostic ratings were all carried out or supervised by the DAWBA's creator, working in conjunction with experienced local professionals. As judged by the DAWBA, the prevalence of any mental disorder ranged from 2.2% in India to 17.1% in Russia. The nine SDQ caseness indicators (three indicators times three informants) explained 8-56% of the cross-national variation in disorder prevalence. This was insufficient to make meaningful prevalence estimates since populations with a similar measured prevalence of disorder on the DAWBA showed large variations across the various SDQ caseness indicators. The relationship between SDQ caseness indicators and disorder rates varies substantially between populations: cross-national differences in SDQ indicators do not necessarily reflect comparable differences in disorder rates. More generally, considerable caution is required when interpreting cross-cultural comparisons of mental health, particularly when these rely on brief questionnaires.

Relações entre experiências anômalas tipicamente contemporâneas, transtornos mentais e experiências espirituais

Background: The anomalous experiences are often an explanatory challenge for psychiatry and psychology about how and why they occur, in addition to signaling gaps in knowledge about human psychological functioning, as hallucinations in non-clinical populations. Objective: It aims to investigate possible psychopathological dimensions of Brazilian samples of persons who claim distinctively contemporary anomalous experiences. Methods: It was used the Mini International Neuropsychiatric Interview, detailed version (MINI PLUS) and the nine diagnostic criteria for the distinction between spiritual experiences and mental disorders with religious content developed by Menezes Junior and Moreira-Almeida. Results: There was evidence that the experiences are typically healthy, although there are indicators of pre-morbid characteristics in the childhood and adolescence of the protagonists of the more complex experiments. There is profitable intersections with healthy squizotype profile, which is still poorly understood. Discussion: The absence of formal mental disorders does not exhaust the possible relations between contemporary anomalous experiences and the mental health field, but reveals complexities that characterize the everyday culture.

Spiritual support for people living with HIV/AIDS: A Brazilian explorative, descriptive study

y In this exploratory and descriptive research, we identified the meaning of religion and spirituality in the experience of patients at a public health service for treatment of HIV/AIDS in a Brazilian upcountry town. Eight participants were selected through theoretical sampling. Data were collected through semistructured interviews, and analyzed by means of qualitative content analysis. The emerging themes were religion: a path to support, and God is everything. Religion, as a path that leads patients to different sources of support, included exploration of different churches, acknowledgment of guilt, and finding strength to cope with the disease, rationalization of the disease process, meeting other churchgoers, and finding God and faith. God, an important source of support, was present in prayers, in the belief in healing through faith, and in the feeling of comfort and relief. Because spirituality and religion were seen as important sources of support, in this study we that health professionals include these aspects in care planning.

Using selected scenes from Brazilian films to teach about substance use disorders, within medical education

CONTEXT AND OBJECTIVES: Themes like alcohol and drug abuse, relationship difficulties, psychoses, autism and personality dissociation disorders have been widely used in films. Psychiatry and psychiatric conditions in various cultural settings are increasingly taught using films. Many articles on cinema and psychiatry have been published but none have presented any methodology on how to select material. Here, the authors look at the portrayal of abusive use of alcohol and drugs during the Brazilian cinema revival period (1994 to 2008). DESIGN AND SETTING: Qualitative study at two universities in the state of São Paulo. METHODS: Scenes were selected from films available at rental stores and were analyzed using a specifically designed protocol. We assessed how realistic these scenes were and their applicability for teaching. One author selected 70 scenes from 50 films (graded for realism and teaching applicability > 8). These were then rated by another two judges. Rating differences among the three judges were assessed using nonparametric tests (P < 0.001). Scenes with high scores (> 8) were defined as "quality scenes". RESULTS: Thirty-nine scenes from 27 films were identified as "quality scenes". Alcohol, cannabis, cocaine, hallucinogens and inhalants were included in these. Signs and symptoms of intoxication, abusive/harmful use and dependence were shown. CONCLUSIONS: We have produced rich teaching material for discussing psychopathology relating to alcohol and drug use that can be used both at undergraduate and at postgraduate level. Moreover, it could be seen that certain drug use behavioral patterns are deeply rooted in some Brazilian films and groups.

Low serum levels of 25-hydroxyvitamin D (25-OHD) in children with autism

Objective: To confirm previous evidence suggesting an association between autism and low vitamin D serum levels. Methods: This preliminary exploratory study assessed the circulating levels of 25-hydroxyvitamin D (25-OHD) in pediatric patients with autism and in typically developing controls from Juiz de Fora, Brazil. Results: Serum levels of 25-OHD were lower in children with autism (26.48 ± 3.48 ng mL-1) when compared to typically developing subjects (40.52 ± 3.13 ng mL-1) (p < 0.001). Conclusion: Our findings attest to the importance of vitamin supplementation during pregnancy and in the treatment of children with autism, who tend to present low vitamin D consumption rates.

Da una sponda all'altra del Mediterraneo: percorsi migratori femminili

Until the end of the 1970s international migrants were perceived and analysed mainly within the frame of their lives in the host country, or as managing their lives and choices caught in a dilemma “between two cultures”. More recently, this approach has been challenged by an image of diasporic communities composed of individuals who “have collective homes away from home”. Migrants have become icons of hybridity and the metaphor of “border crossing”, the symbol of liberatory articulations between place, culture and identity. Migrants, it is also argued, have become transnational as they manage to live simultaneously in two countries. The research has the aim to study the migration process of the women who come from North Africa to Bologna. In particular, it investigates migrant women‘s relations with their adopted country and how their cultural practices are shaped by the transnational dimension of their lives. It was studied the journey of the migrant women’s lives across two countries and how their identities are going to change because of the experience of the migration. Migrant women are engaged in various kinds of practices and experiences through which they connect their country of origin and of residence. So this research focuses on the changes in the migrant women’s lives and the construction of their new identity. In particular, the research illustrates the development of a new notion of modernity, underlining how the migrant women construct a model of modernity that expresses a constant negotiation among diverse cultural models. The notion of modernity is not produced in opposition to tradition and religion, but is articulated with them in complex and diverse ways. The multiple ways in which migrant women understand modernity reflect their divergent identity’s renegotiation processes within the new society where they live.

Women writing Ireland, 1798 – 1921: il popular novel tra identità nazionale e immaginario religioso nelle autrici cattoliche e protestanti.

La presente tesi si concentra sul romanzo popolare irlandese scritto da donne, nel periodo compreso tra il 1798 e il 1921. Quattro sono le autrici prese in considerazione: Charlotte Elizabeth Tonna, Sydney Owenson (meglio conosciuta come Lady Morgan), Edith Somerville e Katharine Tynan, le cui vite e opere coprono un periodo storico fondamentale per l’uscita dell’Irlanda dal dominio coloniale britannico e la formazione della nazione irlandese nel sud del paese. L’interesse principale è quello di analizzare il modo in cui nei loro testi prende forma la nazione, e in particolare attraverso quali immagini e riferimenti religiosi. Il senso è quello, dunque, di rileggere tali testi prestando maggiore attenzione alla religione, uno dei principali collanti tra autrici e pubblico: all’epoca in cui l’Irlanda stava acquisendo i confini che oggi ancora mantiene, esisteva un terreno d’incontro tra discorso politico e letterario, quello della nazione, e tale terreno veniva attraversato anche dal messaggio religioso. Il fine ultimo è quello di dimostrare che la letteratura popolare non è “seconda” ad altre quanto a valori che è in grado di trasmettere e a messaggi che è in grado di veicolare: trascurarla significa non capire i meccanismi attraverso i quali una società si sviluppa e si modifica.

Conservare la cultura, creare una storia. Tradizione e genere nella musica di villaggio dei Banyoro e dei Batooro dell’Uganda.

La dissertazione si articola attorno all’idea di tradizione e alla concettualizzazione di genere nella musica di villaggio dei Banyoro e dei Batooro dell’Uganda occidentale. Il lavoro si sviluppa nel complesso in tre parti principali. Nella prima si presentano le trasformazioni storiche intervenute nelle relazioni di genere dal periodo precoloniale al presente e si introduce la musica di villaggio delle popolazioni considerate, ponendola a confronto con la musica di corte e con quella religiosa. La seconda sezione è dedicata allo studio dei repertori vocali e di danza di villaggio, a partire dalla documentazione realizzata con informatori anziani: di queste musiche sono considerate le caratteristiche stilistiche ed è condotta un’analisi che mira a mettere in luce le idee di genere trasmesse attraverso questi repertori. L’ultima parte del lavoro prende in considerazione le trasformazioni intervenute nel panorama musicale ugandese nell’ultimo secolo, a partire dall’influenza di musiche esterne, dall’insegnamento della musica tradizionale nelle scuole e dall’istituzione di festival scolastici e di gruppi folklorici: diverse performance attuali di canti e di danza sotto sottoposte a studio analitico. Nel complesso, si rileva una generale rifunzionalizzazione di musiche e idee di genere che si rifanno al passato, ma hanno valore soprattutto per il recupero della cultura locale nel presente,connotato dal contesto multiculturale dell’Uganda contemporanea e dalle politiche, promosse dal Governo, che favoriscono l’emancipazione femminile.

Muslimische Theologen und Philosophen im Wett- und Widerstreit um die Ratio - Ein Thesenpapier zum Diktum der 'Vernunftreligion' Islam im 11.-14. Jahrhundert

In this paper I investigate the vivid discussions among Muslim theologians and philosophers about the relationship of reason and religion from the 11th to the 14th centuries – which continue to be used as points of reference today. I argue that the idea of Islam as a religion which is in harmony with reason was one of the key postulates of the dominant thinkers of that period, regardless of their school of thought or their attitude towards literal or allegorical ways of understanding the Coran. In consequence, religion has been rationalized or even intellectualized to a high degree while philosophy in turn has been deeply coloured by religious images and concepts. Yet the understanding of religion as well as of reason and its instruments has been so heterogeneous that rationalization could bear very different, even conflicting meanings, thereby undermining the postulated harmony. In seven theses I foreground several striking similarities and differences between theologians and philosophers who diverge in their usage and understanding of reason as well as of the nature of religion.

Mental scanning in auditory imagery for songs

Four experiments examined how people operate on memory representations of familiar songs. The tasks were similar to those used in studies of visual imagery. In one task, subjects saw a one word lyric from a song and then saw a second lyric; then they had to say if the second lyric was from the same song as the first. In a second task, subjects mentally compared pitches of notes corresponding to song lyrics. In both tasks, reaction time increased as a function of the distance in beats between the two lyrics in the actual song, and in some conditions reaction time increased with the starting beat of the earlier lyric. Imagery instructions modified the main results somewhat in the first task, but not in the second, much harder task. The results suggest that song representations have temporal-like characteristics.

Duration discrimination in a series of rhythmic events

Duration discrimination of the last of a series of four clicks was investigated. Examination of psychophysical functions from eight subjects revealed evidence for a Weber’s law model relating discrimination to base interclick interval. Also, the point of subjective equality was seen to change reliably as a function of base rate.
